    [0014] STATEMENT OF THE INVENTION
    [0015]
    [0016] The object of the invention is to provide an automatic start and stop module configured to be integrated into a vehicle and an associated method, as defined in the claims.
    [0017]
    [0018] The automatic stop and start module of the invention comprises a supercapacitor to generate the necessary intensity to start the vehicle. In the automatic start and stop module of the invention, the supercapacitor comprises an aqueous electrolyte. Furthermore, the automatic start and stop module of the invention is configured to be installed in a conventional vehicle, converting it after installation into a micro-hybrid vehicle.
    [0019]
    [0020] The automatic start and stop module of the invention is suitable for use in motor vehicles that require high starting power and have very high starting resistance torques. These are large vehicles with thermal engines of gasoline, diesel, CNG (Compressed Natural Gas), LPG (mixture of butane and propane) or biogas, which can use from 6 to 12 cylinders, and with displacements of between 10,000 and 20,000 cubic centimeters, such as urban mass transit vehicles, industrial vehicles and heavy vehicles.
    [0021]
    [0022] On the other hand, the automatic stop and start module of the invention is integrable in conventional vehicles by means of a simple installation, understanding as a conventional vehicle that which is not a micro-hybrid vehicle, converting the conventional vehicle into a micro-hybrid vehicle. In conventional vehicles, the engine compartment does not have enough free space to install an automatic start and stop module comprising a supercapacitor. The module of the invention can be installed without any problem in the passenger compartment because the aqueous electrolyte is a harmless substance for humans. Furthermore, the supercapacitor presents no risk of explosion, combustion, or spillage when subjected to large temperature changes or strong vibrations, and does not require closed-loop control.
    [0023]
    [0024] The control method associated with the automatic start and stop module of the invention comprises an initial stage of checking the battery charge level and the external temperature of the vehicle. The method then comprises a stage of starting the vehicle from the battery if the battery charge level is greater than or equal to a threshold level and if the outside temperature is greater than or equal to a minimum temperature, or a vehicle starting stage using the supercapacitor if the battery charge level is below this threshold level or if the outside temperature of the vehicle is lower at a minimum temperature. In the step of starting the vehicle using the supercapacitor, a sub-stage of charging the supercapacitor from the battery is executed, and then a sub-stage of starting the vehicle from the supercapacitor. The vehicle start stage is understood to be the stage of the first start of the vehicle, whether it is carried out using a key, or any other means known in the state of the art that allows the first start of the vehicle to be carried out.
    [0025]
    [0026] The method of the invention allows the replacement of the vehicle battery to be delayed, allowing the first start of the vehicle to be carried out using the supercapacitor. Also, the method of the invention allows the vehicle to be started from the supercapacitor when the outside temperature is very low, a situation in which the battery probably could not start the vehicle on its own. The method of the invention allows the vehicle to be started from the supercapacitor when the outside temperature is very low even if the battery is capable of starting the vehicle on its own, thereby avoiding accelerated deterioration of the battery, since the intensity that the Supercapacitor demand of the battery for its charge is minimal, and it hardly supposes charge for the battery.
    [0027]
    [0028] These and other advantages and characteristics of the invention will become apparent in view of the figures and the detailed description of the invention.

    [0030] DESCRIPTION OF THE DRAWINGS
    [0031]
    [0032] Figure 1 shows a simplified electrical schematic of part of the connections to be made in the installation of an embodiment of the stop and start module of the invention.
    [0033]
    [0034] DETAILED EXHIBITION OF THE INVENTION
    [0035]
    [0036] Figure 1 shows an embodiment of the automatic stop and start module for a Motor vehicle.
    [0037]
    [0038] The automatic start and stop module of the invention comprises a supercapacitor 1 to generate the intensity necessary to start the vehicle. In the automatic stop and start module of the invention, the supercapacitor 1 comprises an aqueous electrolyte. Furthermore, the automatic start and stop module of the invention is configured to be installed in a conventional vehicle, converting it after installation into a micro-hybrid vehicle.
    [0039]
    [0040] In the automatic stop and start module of this embodiment, the aqueous electrolyte of supercapacitor 1 is based on potassium hydroxide or sodium hydroxide. Both potassium hydroxide and sodium hydroxide are harmless to humans. In addition, a supercapacitor using potassium hydroxide or sodium hydroxide as the aqueous electrolyte does not present a risk of explosion, combustion, or spillage when subjected to large temperature changes or strong vibrations, and does not require closed-loop control. That is why the supercapacitor 1 can be installed in the passenger compartment of the vehicle.
    [0041]
    [0042] The supercapacitor 1 of the automatic stop and start module of this embodiment is an active carbon based supercapacitor 1. A supercapacitor based on activated carbon and with potassium hydroxide or sodium hydroxide as aqueous electrolyte, has an equivalent series resistance or ESR lower than that of other supercapacitors known in the state of the art, which allows the supercapacitor to heat up less and also have a greater capacity to deliver power.
    [0043]
    [0044] Supercapacitors based on activated carbon, and with potassium hydroxide or sodium hydroxide as aqueous electrolyte, have a high power density, which makes it possible to occupy less space than supercapacitors manufactured by other technologies. Also, for the same power supplied as supercapacitors made by other technologies they have less weight.

    [0092]
    [0093] In the control method associated with the automatic start and stop module of the invention, automatic stop and start are disabled if a measured engine temperature is not within a previously defined temperature range for said engine temperature. It is not advisable for the vehicle to start and stop automatically after the vehicle is started for the first time or to start from the key until the engine temperature has not reached a level, preferably between 70 and 80 ° C, and until the engine is lubricated. The method of the invention enables the automatic stopping and starting of the vehicle to be disabled, until the optimal conditions for it exist, thus avoiding accelerated deterioration of the vehicle's engine. By disabling the automatic stop and start of the vehicle, the vehicle behaves as if it did not have the stop and start module of the invention installed.
    [0094]
    [0095] In the control method associated with the automatic start and stop module of the invention, automatic stop and start are disabled if the difference between a temperature measured inside the vehicle and a previously defined temperature range for said vehicle exceeds a certain threshold. The previously defined temperature range for the vehicle is stored in the data storage media of the digital controller.
    [0096]
    [0097] In urban public transport vehicle fleets, it is common to define comfort conditions for the vehicle, which define, among others, a range of acceptable temperatures for the interior of the vehicle.
    [0098]
    [0099] In the control method associated with the automatic stop and start module of the invention, the stop and automatic start are disabled if the difference between a temperature measured outside the vehicle and validated by the digital controller, and a temperature measured inside the vehicle exceeds a certain threshold. If the vehicle comprises several exterior temperature sensors, or several interior temperature sensors, the interior and exterior temperatures are calculated as the average of the temperatures measured by the interior and exterior temperature sensors respectively. The digital controller has external vehicle reference temperatures stored in the data storage media, which the digital controller uses to validate if the measured temperature outside the vehicle is correct. Reference outside temperatures vary based on vehicle location, date, and time.
    [0100]
    [0101] When the automatic stop of the vehicle is activated, the vehicle engine stops, however, a plurality of elements of the vehicle such as the music system and the lights continue to operate normally, obtaining the necessary energy for this from the battery 3. The The air conditioning compressor demands a quantity of energy that can, after continuous automatic stops of the vehicle, affect the charge level of the battery 3. That is why every time an automatic stop of the vehicle is made, the digital controller sends a signal to the interior lights of the vehicle through the outputs of the control board in which it is indicated to lower their intensity. Also, the digital controller sends a signal to the vehicle's air conditioning compressor through another output on the control board indicating that it stops. Finally, the digital controller sends a signal to the vehicle's air conditioning fans through the outputs on the control board, indicating that they slow down.
    [0102]
    [0103] By means of the control method associated with the automatic start and stop module of the invention, it is possible to disable the automatic stop and start of the vehicle when it is expected that the comfort conditions defined for the vehicle cannot be guaranteed, thus preventing the vehicle air conditioner to stop during vehicle stops.
    [0104]
    [0105] In the control method associated with the automatic start and stop module of the invention, automatic stop and start are disabled if the pressure of the vehicle's pneumatic system does not exceed a threshold value. It is necessary that the pressure of the pneumatic system exceed this threshold value to guarantee the correct operation of the brake system of the vehicle, such as opening and closing doors. If this threshold value is not exceeded, the stop and automatic start are disabled, and the vehicle starts operating as if it did not have an automatic stop and start module installed.
    [0106]
    [0107] In the control method associated with the automatic start and stop module of the invention, the digital controller electronically acts on the vehicle's gearbox when automatically stopping, changing the gearbox gear to a neutral position. The digital controller then stores in memory the vehicle gear in which the gearbox was located before the automatic stop was made, and changes the gearbox gear to the previously memorized gear when the vehicle is started automatically.
    [0108]
    [0109] In the control method associated with the automatic start and stop module of the invention, the automatic stop is carried out if the vehicle wheels are stopped and in addition a stop brake, a parking brake is activated, or the central door is opened and / or rear of the vehicle. For the purposes of the present invention, a stop brake shall be considered to be the brake that the vehicle driver activates when performing a stop in which the driver does not get off the vehicle, such as a stop for loading or unloading passengers to the vehicle, or a stop at a traffic light. For the purposes of the present invention, a parking brake is a brake that, when activated by the driver, applies pressure to a plurality of wheels of the vehicle, thereby blocking their movement. The parking brake is normally used at uphill stops.
    [0110]
    [0111] In the control method associated with the automatic start and stop module of the invention, automatic start is performed by pressing the accelerator.
    [0112]
    [0113] In the control method associated with the automatic stop and start module of the invention, the automatic start is performed by closing at least one of the vehicle doors, passing the vehicle to a state in which all its doors are closed, if none of the doors are closed. the stop and parking brakes are not activated.
    [0114]
    [0115] In the control method associated with the automatic start and stop module of the invention, an automatic stop of the vehicle will be carried out if, after a previously established period of time to carry out the automatic start of the vehicle, no action on the vehicle. The previously established period of time may be extended by additional periods of previously established duration if the vehicle's accelerator is depressed before the last active period of time is exhausted. The previously established time period will preferably be 30 seconds, and each of the additional time periods will preferably be 30 seconds.
