    SYSTEM FOR MANAGING AN ETHERNET NETWORK ON AN OPTICAL FIBER
    VEHICLE The invention relates, in general, to the field of on-board communication networks in a vehicle. The invention relates in particular to a system for managing an Ethernet network on optical fiber of a motor vehicle.
    In general, a motor vehicle comprises a plurality of on-board computers allowing the control of the various functions of the vehicle, such as the engine ignition controls, the safety controls, such as the airbags or the signaling lights for example, or even the comfort controls accessible from the passenger compartment of the vehicle, such as heating or closing and opening the windows, for example.
    In known manner, each on-board computer, dedicated to a set of functions (engine functions, safety functions or comfort functions in the example cited above), is connected to a computer designated “master computer”, configured to control each of the other on-board computers, designated “slave computers”.
    To do this, the master computer communicates with all the slave computers via a local communication network, designated the Ethernet network. Such a communication network thus connects the master computer to a plurality of slave computers, all the computers of the vehicle being connected to each other so as to allow the coordination of the actions of each.
    In known manner, such a network of computers is controlled to be put in a "standby" state or a "waking" state according to the needs of the vehicle or the driver, so as to allow energy saving of the vehicle. for example. Such passages in a standby or awake state must be synchronized between all the computers on the network in order to limit data loss.
    As such, there is a known system for managing an Ethernet network of a motor vehicle, enabling the network to wake up and go to standby. Such a system comprises a main computer connected to the Ethernet network via a pair of twisted cables of the 100Base-T1 type, commonly known as Ethernet cables. The main computer is configured to manage the awakening and the standby of secondary computers via a wired link connecting all the computers. However, nowadays, Ethernet cables are more and more replaced by 100Base-TX fiber optic cables, less subject to disturbances. In known manner, communication by optical fiber is in the form of a light signal configured to move along such a fiber. This is commonly referred to as an Ethernet network over fiber optics.
    For such Ethernet networks on optical fiber integrated into a vehicle, the state of the art does not provide a system for managing the network, such as putting all of the computers in the network to standby or waking up. example.
    Indeed, it is known in document FR 3031856, an Ethernet switch for a network on optical fiber comprising a transmitter, configured to transmit a light signal by a fiber optic cable, and a receiver, configured to receive such a signal bright and convert it to an electrical signal. The switch described in document FR 3031856 further comprises a power supply circuit and a wake-up circuit configured to generate an electric wake-up signal on receipt of the light signal. Such a wake-up circuit is connected to the power supply circuit, allowing the ignition of such a transmitter to be started.
    However, such a switch is not applicable to an Ethernet network on optical fiber of a motor vehicle, which has a major drawback.
    The invention therefore aims to at least partially overcome these drawbacks by proposing a simple and effective system for managing the state of a communication network of a vehicle of Ethernet type on optical fiber.
    More specifically, to achieve this result, the present invention relates to a management system of a multiplexed communication network of a vehicle, said management system comprising a plurality of computers connected to said communication network, and a link bidirectional wired connecting said plurality of computers together, said communication network and said plurality of computers having a standby state and an awake state, said plurality of computers comprising a master computer and at least one slave computer, said master computer and said to the at least one slave computer being configured to send and receive a message relating to a requested state of the communication network via said bidirectional wired link, the state of at least one of the plurality of computers being controlled from said message relating to the requested status, so as to control the status of the network communication water, said communication network being of Ethernet type on optical fiber.
    Such a management system advantageously makes it possible to control the standby and the awakening of an Ethernet communication network on optical fiber, thus allowing energy saving of the vehicle systems. Thanks to such a management system, the state of such an Ethernet fiber optic communication network can be controlled from messages received by one of the computers via the bidirectional wired link.
    Advantageously, any computer in the communication network can control the alarm clock by activating the wired link which is bidirectional.
    Advantageously, said message relating to said state of the communication network corresponds to a change of state of a signal sent by the master computer and / or by said at least one slave computer via the bidirectional wired link.
    Preferably, said transmitted signal having a high state and a low state, said high state or said low state of the signal corresponds to the awake state of the communication network and the other of said high state or said low state of the signal corresponds to the standby state of the communication network.
    Advantageously, said master computer and said at least one slave computer are respectively configured to send and receive, via the communication network, a confirmation message relating to said requested state, making it possible not to wake the network when the wake-up request has not been validated by the master computer.
    Advantageously, the system comprising a first slave computer and at least a second slave computer, said at least one second slave computer being connected to the master computer and to said first slave computer by a bidirectional wired link, at least one of the computer master or of the first slave computer comprises a switch configured to connect said at least one second slave computer to the communication network, making it possible to control all the computers of the network.
    The invention also relates to a motor vehicle comprising an Ethernet communication network on optical fiber and a state management system of said communication network as described above.
    The invention finally relates to a method for managing a multiplexed communication network of a vehicle, said vehicle comprising a management system of said communication network having a standby state and an awake state, said management system comprising a master computer and at least a first slave computer, said communication network being of Ethernet over optical fiber type, said method comprising a phase of awakening said communication network comprising:
    - a step of activating said bidirectional wired link,
    a step of sending by said master computer or by said first slave computer of a wake-up message from the communication network via the bidirectional wired link,
    a step of reception by the other of said master computer or of said first slave computer of said wake-up message, and
    a step of awakening said master computer and said first slave computer, causing the communication network to be awakened.
    Advantageously, said step of sending a wake-up message from the communication network being carried out by the first slave computer, the method comprises, after the step of reception by the master computer of said wake-up message, a step of sending by the master computer to said at least one first slave computer of a message confirming the awakening of the communication network via the communication network.
    Preferably, the management method comprises a step of reception by the first slave computer of said confirmation message.
    Advantageously, said management system comprising at least a second slave computer connected to said first slave computer and to said master computer by the bidirectional wired link, the step of receiving said wake-up message is also carried out by said at least one second slave computer, and the wake-up step further causes the second slave computer to wake up.
    Similarly, said management system comprising at least a second slave computer connected to said first slave computer and to said master computer by the bidirectional wired link, the step of sending by the master computer of a wake-up confirmation message of the communication network via the communication network advantageously makes it possible to send said alarm confirmation message to the first slave computer and to said at least one second slave computer.

    In what follows, the embodiments described relate more particularly to the installation of a management system of a communication network according to the invention within a motor vehicle. However, any installation in a different context, in particular in any type of vehicle, is also covered by the present invention.
    As is known, a motor vehicle comprises a plurality of on-board computers, designated slave computers 20, allowing, when activated, to actuate a control of the vehicle. The actuation of an order is carried out for example by the emission of a message, received by the equipment concerned by the order.
    To do this, such slave computers 20 are connected to a master computer 10 via a multiplexed W communication network. Such a master computer 10 is thus configured to control each of the slave computers 20.
    The communication network W described in this invention is an Ethernet type network on optical fiber, having the advantage of being a local area network with very high data transfer speed, making it possible to limit disturbances.
    Referring to Figure 1, a motor vehicle (not shown) comprises a management system 1 according to the invention. Such a management system 1 thus comprises a master computer 10, a plurality of slave computers 20 and a network W of Ethernet multiplexed communication on optical fiber connecting said computers 10, 20 to each other. According to a preferred embodiment of the invention, the Ethernet communication network W on optical fiber further comprises an additional bidirectional wired link L connecting each master computer 10 and slave computer 20 of the network W.
    The master computer 10 is configured to transmit a message via the W Ethernet network on optical fiber, making it possible to manage the state of such a network W. In other words, the master computer 10 is configured to control each slave computer 20 in order to place them in a specific state. Such management of the network W advantageously makes it possible to use the computers 10, 20 connected to the network W only when this is necessary.
    In this example, the management system 1 comprises four slave computers 20, each dedicated to a specific function of the vehicle. However, it goes without saying that the management system 1 could include a different number, in particular a single slave computer 20 or at least two slave computers 20.
    In the remainder of this document, the communication network W connecting the computers 10, 20 to each other is understood by the terms "waking up / putting the communication network W on standby" >>, waking up or putting on standby of all the computers 10, 20 connected by such a communication network W.
    Each computer 10, 20 of the management system 1 is configured to send and receive messages relating to the state of the communication network W via the bidirectional wired link L. Such messages correspond to changes of state aO, a1 of a signal S1, S2, S3, S4, S5 generated via such a bidirectional wired link L. The master computer 10 and the slave computers 20 are further configured respectively to send and receive a confirmation message relating to the state of the communication network W via said communication network W.
    In this example, each computer 10, 20 is thus configured to control the waking up of the network W, with the aim of placing the latter in an "awake" state. Also each computer 10, 20 is configured to send a wake-up message via the bidirectional wired link L. In addition, the master computer 10 is further configured to control the standby of the network W, with the aim of placing the latter in a "standby" state.
    When the wake-up request message is sent by a slave computer 20, on receipt of such a wake-up message, the master computer 10 is also configured to wake up and send a wake-up confirmation message to the set of slave computers 20 via the communication network W. In addition, on receipt of such a wake-up message sent by one of the slave computers 20, each slave computer 20 is configured to wake up and wait for the confirmation message transmitted by the master computer 10.
    Each slave computer 20 is thus connected to the master computer 10 so that said master computer 10 controls the state of the slave computers 20. Also in order to connect each master computer 10 and slave 20 to the communication network W, one of the computers 10, 20, includes a switch 30 (shown in Figure 1), also designated "switch" in English. All the computers 10, 20 are connected to such a switch 30 so as to be linked together by the communication network W.
    In the example illustrated in Figure 1, a first slave computer 20 includes such a switch 30, however it goes without saying that the master computer 10 could, alternatively, include the switch 30.
    The bidirectional wired link L, configured to connect each computer 10, 20 to all the other computers 10, 20 of the management system 1, allows the master computers 10 and slaves 20 to activate the alarm clock (or standby ) of the communication network W.
    To do this, with reference to FIGS. 2 to 4, each computer 10, 20 is configured to generate an electrical signal S1, S2, S3, S4, S5 on the bidirectional wired link L. Such signals S1, S2, S3, S4, S5 include a high state a1, corresponding to the activation of the bidirectional wired link L, and a low state aO, corresponding to the deactivation of the bidirectional wired link L. Each state aO, a1 is thus associated with a communication network state W.
    In this example, the high state a1 of the bidirectional wired link L is associated with the waking state of the network W and the low state aO of the bidirectional wired link L is associated with the standby state of the network W. It goes without saying that the association of the states aO, a1 could be reversed.
    The signal S1, illustrated in FIG. 2, represents the activation by the master computer 10 of the bidirectional wired link L in the case of the wake-up command of the communication network W by the master computer 10.
    The signal S2, illustrated in FIG. 3, represents the activation of the bidirectional wired link L by a slave computer 20. This activation causes the master computer 10 to maintain the activation of the directional wired link L shown by signal S3 as long as the communication network W is awake. The signal s4 represents the result of the electrical signals S2 and S3 on the bidirectional wired link L.
    The signal S5, illustrated in FIG. 4, represents the deactivation of the bidirectional wired link L by the master computer 10 in order to control the standby of the communication network W.
    Thanks to the management system 1 according to the invention, the awakening and the standby of the computers 10, 20, and therefore of the communication network W, can be controlled via the bidirectional wired link L. In addition, such a wired link L being bidirectional, each computer 10, 20 can control the awakening of the other computers 10, 20, and therefore of the communication network W, as will be described later. Likewise, the master computer 10 can also control the standby of the slave computers 20, and therefore of the communication network W, allowing for example an energy saving of the vehicle systems.
    There will now be presented a method for managing the state of the network W of Ethernet communication on optical fiber according to the invention, according to a preferred embodiment of the invention. With reference to FIGS. 2 to 6, such a network W comprises a master computer 10 and a plurality of slave computers 20. In this example, the management method has a wake-up phase and a standby phase.
    FIG. 2 illustrates, in the wake-up phase, the awakening of the communication network W controlled by the master computer 10, as described previously, FIG. 5 describing a method for managing the wake-up of the network W requested by the master computer 10 In this case, the master computer 10 is awakened locally and activates, in a step E1 A , the bidirectional wired link L, allowing the sending of a wake-up message in a step E2 a . For this purpose, the signal S1 emitted by the master computer 10 on the bidirectional wired link L then passes, in this step E1 A , from the low state aO to the high state a1.
    The slave computers 20 detect the change of state aO, a1 of the bidirectional wired link L. The slave computers 20 therefore receive the wake-up message, in a step E3a, and wake up, in a step E6a, causing the awakening of the communication network W, which remains awake.
    Alternatively, in this wake-up phase, the W network can be woken up by a first slave computer 20, as illustrated in FIG. 3 and the method of which is shown in FIG. 6. In this case, a such a first slave computer 20 is awakened locally and activates, in a step E1 B , the bidirectional wired link L, allowing the sending of a wake-up message, in a step E2 B. For this purpose, the signal S2 emitted by the first slave computer 20 on the bidirectional wired link L goes from the low state aO to the high state a1.
    The master computer 10 and the other slave computers 20 then detect the change of state aO, a1 of the bidirectional wired link L. All the computers 10, 20 therefore receive the wake-up message, in a step E3 B , and then wait for a wake-up confirmation message.
    The master computer 10 then sends, in a step E4 B , a wake-up confirmation message, received by all of the slave computers 20, in a step E5 B. The reception of such a message leads to the awakening of all the computers 10, 20 of the network W, in a step E6 B. To do this, the signal S3 goes from the low state aO to the high state a1 in order to keep the communication network W awake. The state of signal S3 is maintained as long as the network W is awake. Thus, the result of the signals S2 and S3 is the signal S4, the change of state of which is detected by all the computers 10, 20.
    Advantageously, maintaining the high state a1 by the master computer 10 of the signal S4 transmitted on the bidirectional wired link L, the computers 10, 20 are kept awake even in the event of loss of the communication network W.
    In a standby phase, the master computer 10 can also control the standby of the communication network W, as illustrated in FIG. 4. In this case, the master computer 10, initially woken up, sends a standby message and thus generates the signal S5 on the bidirectional wired link L which goes from the high state a1 to the low state aO.
    The slave computers 20 detect the change of state aO of the signal S5 via the bidirectional wired link L and receive the standby message via the communication network W. The slave computers 20 then go to standby, which has the effect of putting the communication network W on standby.
    Such a management system 1 advantageously makes it possible to control, via a bidirectional wired link L, the network W of Ethernet communication on optical fiber fitted to a vehicle, thus allowing a standby of such a network W, when this is possible, saving energy for example. Such a network W can also advantageously be woken up either by the master computer 10 or by the slave computer 20, since the wired link L according to the invention fitted to the network is advantageously bidirectional.
