A method for eliminating hydrocarbon vapors generated in a fuel tank of a vehicle powertrain including at least one heat engine, by a canister adapted to absorb the vapors. The method includes detecting movements of the hydrocarbon vapors from the tank to the canister, increasing a counter value when the vapors move from the tank to the canister, and calculating a number of gas volumes passing through the canister when the heat engine is started so as to reduce the value of the counter by purging the gasoline vapors in a direction of the engine.

Method and device for eliminating hydrocarbon vapours for a vehicle

A device for generating a radiofrequency plasma, that includes a voltage generator, and at least one ignition assembly that includes an ignition plug and a switch provided between a supply terminal of the plug and an output of the generator adapted for electrically connecting the output of the voltage generator to the plug upon reception of a control signal, and an electronic control unit generating the control signal. The electronic control unit measures values representative of evolution in time of the output voltage of the generator. The device further includes a mechanism varying the voltage and/or the frequency of the electric current applied to the supply terminal of the plug based on measured values. The evolution of the generator output voltage is representative of the condition of the plug (new or used).

Device for generating radiofrequency plasma

A method for controlling a motor vehicle. According to the method, a volumetric filling efficiency for air in the motor is determined using a network of artificial neurones.
