    capable of receiving, processing and sending information to the device 1. Throughout the memory of the present invention, "information" may include instructions, data, parameters, parameter values, operating errors stored in the ECU and data.
    In the exemplary embodiment shown in Figure 1, the device for monitoring and storing data and remotely modifying vehicle parameters 1 performs centralized information management. For this, the device 1 comprises the connection input interface 4 with the ECU (Electronic Control Unit) 3 of the vehicle 2, the output interface 5, the management module of the connection interface 6 with the ECU 3, the module GPS 7, which measures and records the position of the vehicle 2, the accelerometer module 8, which measures and records the accelerations / decelerations of the vehicle as well as the inclination and turns of the vehicle 2 with respect to the X, Y and Z 29 axes, the module of data management and storage 9, which records and stores the parameters read from the ECU 3, the management module of the connection interface 6, the GPS module 7 and the accelerometer module 8, and the communications module 10. In this way , the device 1 is capable of continuously monitoring the use, condition and behavior of the vehicle by recording in each unit of time the data obtained by the ECU with which the vehicle position, acceleration / deceleration are associated. is suffered at that time along with the date and time at which the reading occurs. This monitoring is especially important when the ECU records errors in one or more vehicle parameters. Once all the parameters have been monitored, the device 1 is able to store the data and send it to a remote server 17 or remote station for storage and analysis, and even for a subsequent modification of the ECU parameters, a firmware update of the device 1 and / or ECU, encryption management, authorization management, etc. To send the recorded data 20 and stored and / or to receive information (instructions 18, parameters 19 and their values and / or firmware), the device 1 has the information stored in the data management and storage module 9 which it sends it to the remote server 17 by means of the communications module 10. The device 1 can send the information only in the moments in which the remote server 17 makes a request, continuously in real time or store the data registered in its memory internal and initiate a communication with the remote server 17 to send the data recorded since the last communication. This last option is especially interesting if the device 1 finds an open Wi-Fi network for example, it initiates a data call and sends the information stored since the last send. This has the advantage that it would be free when not using mobile phone networks. It is also the device
    9
    which, on its own initiative, makes an emergency call using the communication module 10 when it detects an emergency situation through the accelerometer module 8 or when the alarm / panic button 30 is activated. The alarm / panic button 30 is connected to the data management and storage module 9 such that if it is pressed for a time longer than a preset time (for example 6 seconds) and / or decelerations greater than a predetermined value (1.5 times gravity) are detected and / or inclinations greater than a predetermined value (inclinations greater than 60º with respect to at least one of the three axes X, Y, Z), sends an alert to the remote server and / or emergencies in such a way that the location and the latest data are communicated vehicle. This is useful in the event that an accident or a serious problem has occurred that the system itself does not detect and would allow to come to your aid. Ex: a health problem, an accident without a major deceleration, a kidnapping, etc. The button does not have to be on the same device. It may be hidden elsewhere in the vehicle. Clarify that the connections shown in the figures between the internal components of device 1 and even connections with other devices may include data and / or power. The management module of the connection interface 6 comprises its own processor 11, memory 12 and I / O ports 13 for monitoring and modification of the ECU and the exchange of information with the data management and storage module 9. For its In part, the data management and storage module 9 comprises its own processor 14, memory 15 and I / O ports 16.
    In addition to recording the position of the vehicle, the GPS module 7 is responsible for synchronizing the internal clock of the device 1. In the embodiment shown in Figure 1, the GPS module 7 further comprises an electronic compass 7A, which calculates the orientation of the vehicle with respect to the Earth's magnetic field The electronic compass is optional since the vehicle's orientation could be calculated by knowing the GPS positions in two consecutive moments.
    The accelerometer module 8 comprises accelerometer sensors 8A that measures the accelerations / decelerations in the three axes (X, Y, Z) and also comprises one or several gyroscopes 8B that measures or measures the turns of the vehicle on each of the three axes (X ,AND Z). In the event of a collision, it would be known what accelerations the vehicle has suffered, but also whether it has been vertical or not. This data is essential to know if the accident has been serious to be able to transmit it to emergencies.

    On the other hand, the communication module 10 has associated a WiFi module 21 for WiFi / Bluetooth connections, and a 3G / 4G / 5G module 22 for 3G / 4G / 5G connections.
    On the other hand, the device 1 implements security functions by means of the encryption module 23. In this way, the device 1 can send and receive encrypted information that prevents unauthorized manipulations of the device 1.
     The device 1 in addition to saving any vehicle error identified and registered by the OBD system, together with the date and time of said error, saves the data recorded by the ECU at the time of said error, records any access through the OBD to the ECU of the vehicle, it records any change of parameters made to the ECU of the vehicle, whether through authorized access or not, and records the sending and receiving of information made through the communications module.
    Regarding the power of the device 1, the device 1 is powered by the ECU 3 when it provides power, otherwise, the device 1 has a rechargeable battery 24. In the event that the battery 24 remains discharged, it is possible to start the device 1 only with the current delivered by the vehicle. If the battery is damaged, it will be registered on device 1 as an error. The operation of the rechargeable battery 24 is performed by the device 1 in such a way that it decides whether it should be charged or not. The device 1 will try to ensure that the rechargeable battery 24 is always charged. If the device 1 detects that the rechargeable battery 24 is defective it would register it and communicate it to the remote server by any of the mechanisms described above. Optionally, the device 1 may comprise another rechargeable battery supporting the rechargeable battery 24 in order to increase the reliability of the device 1, since it is essential that it does not run out of battery because certain functions are necessary without vehicle power. For example, in the event of an accident, if the vehicle's battery is lost, the device would detect that there has been a collision and that it is necessary to make a (data) call indicating the position, time and inclination of the vehicle with respect to the vertical axis.
    Additionally, the device 1 can comprise a humidity detector 28 which serves to know if the device 1, when it exhibits malfunctions, has been submerged in water or has operated in too humid environments.
    To improve the immunity against electromagnetic radiation of the device 1, preferably the device has a layered configuration as shown in Figure 2. The device is configured in three layers 25A-25B-25C, such that the connector OBD male 26 (input interface 4), the OBD connector

    or send 35, from the device to the remote server, all the data from the moment indicated by the server and record the date error, when the moments are different;
    or send 34, from the device to the remote server, all the data from the moment indicated by the server, when the moments are coincident and update the date of sending and receiving data both on the remote server and on the device.
    The above method is a method of bidirectional identification and synchronized data delivery. That is, they identify each other device and remote server. Additionally, only the data is exchanged since the last data exchange. This method is optional since it is not strictly necessary for there to be identification or synchronization, although it is a preferred way because it increases the security of the set (remote server-device) and optimizes the sending of data.
    Figure 7 illustrates a flow chart of the vehicle data monitoring and storage method. The method comprises the following steps:
    a) read for each time unit defined a data of the ECU 40 of a vehicle by means of a management module of the connection interface with the ECU; b) read for each time unit defined the position of the vehicle 41
    by a GPS module;
    c) read for each time unit defined the accelerations and decelerations of the vehicle in the three axes of the space, as well as its inclination 42 by means of an accelerometer module;
    d) associate 43 in a synchronized way, using the GPS module, the data read from the ECU with those of the vehicle position, acceleration / deceleration, date and time;
    e) record 44 in the internal memory of the device the data indicated in the previous steps;
    f) send 45, at the initiative of the device or at the initiative of the remote server, by the device, the data recorded in the previous step to a remote server by means of a communications module. The ECU data from step a) also includes possible errors
    stored in the ECU. This is especially important because the vehicle position, possible accelerations or decelerations suffered at the time of the error are associated with the stored error, together with the exact moment (date and time) at which the error occurs.
