  • Patent number: 9890743
    Abstract: 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.

  • Patent number: 9874588
    Abstract: A method for determining an average value of a periodic or quasi-periodic voltage signal that can be transmitted on a communication bus with a transmission period greater than the period of the signal. The method includes acquiring measurements of the signal with a measurement period corresponding to the transmission period of the average value on the bus, obtaining the average value from the acquired measurements, applying, for each measurement, a variable delay, defining a time of measurement within the measurement period, relative to a reference time, and obtaining the average value from the result of the measurement made at each time of measurement and from the results of the measurements made previously.

  • Patent number: 9862380
    Abstract: A method for automatically controlling a vehicle includes giving a reference local path and a potential speed of the vehicle. The method also includes calculating a stirring angle automatic setpoint that makes it possible to calculate a lateral acceleration proportional to the square of the potential speed of the vehicle, making the vehicle describe an arc of a circle including a point of intersection with the reference local path at a distance from the vehicle. A speed setpoint is generated and set to a value equal to that of the potential speed when the lateral acceleration has a value lower than a maximum permissible lateral acceleration value and the value of the potential speed is decreased when the lateral acceleration has a value higher than or equal to the maximum permissible lateral acceleration value so as to calculate a reduced lateral acceleration by repeating the calculating.

  • Publication number: 20170369048
    Abstract: A method manages a state of charge of a traction battery of a rechargeable hybrid vehicle including a hybrid power train to provide propulsion. The battery being capable of operating according to a first operating mode over a state of charge range, of which an amplitude is bounded by predefined maximum and minimum state of charge values, in which the battery supplies substantially all power necessary for propulsion, and a second operating mode, in which the state of charge of the battery is kept substantially constantly around an equilibrium state of charge value. The method includes estimating an ageing state of the battery, comparing the estimated ageing state of the battery in relation to a given ageing state threshold, and reducing the amplitude of the state of charge range linked to the first operating mode when the ageing state of the battery rises above the given ageing state threshold.
