Abstract: A method is provided for controlling operation of a hybrid automotive vehicle equipped with at least an internal combustion engine and an electric machine, each adapted to deliver torque to a driveline of the vehicle. This method includes at least the following steps: a) determination of the ability of the engine to deliver torque to an output shaft and allotment of a value to a first parameter on the basis of this determination, b) determination of the ability of the electric machine to deliver torque to its output shaft and allotment of a value to a second parameter on the basis of this determination, d) computation of a value of a global parameter, on the basis of the respective values of the first and second parameters, and e) generation of an electric or electronic signal representative of the value of the global parameter. The hybrid automotive vehicle of the invention includes means to generate an electronic signal depending on the ability of the engine and/or the electric machine to move the vehicle.

Abstract: The invention relates to a method of controlling the power supply to an electric starter that drives heat engine of a vehicle, in which the starter power supply is stopped after each supply phase for a first pre-determined period TOFF. According to the invention, the starter power supply is inhibited for a second pre-determined period TREP which is longer than the first period TOFF, when the number NON of consecutive starter supply phase ON1, ON2, ON3, ON4 exceeds a pre-determined value NMAX without the heat engine reaching an autorotation state.
