Abstract: A method for starting a combustion engine fitted to a hybrid or dual-mode motor vehicle includes starting an additional motor upon a setpoint torque demanded by a driver of the vehicle, with a view to accelerating the vehicle beyond a threshold speed at which the combustion engine is driven beyond a stalling speed threshold when the combustion engine is mechanically coupled to wheels of the vehicle.

Abstract: A method controls a motor vehicle including an internal combustion engine coupled to a first axle set and to at least two electric machines each one coupled to one wheel of a second axle set. The method includes determining the speed of at least one of the electric machines; comparing the determined speed against a threshold; and altering, if the determined speed is above the threshold, the maximum torque of the electric machines so as to limit the rotational speed of the machines.

Abstract: A vehicle control system for a motor vehicle includes functional modules for controlling elements of the vehicle, a fault management module generating confirmed fault signals from fault data, and a global management module for the operating modes of the vehicle. The global management module generates a mode signal when it detects at least one confirmed fault signal and distributes, to the functional modules, the mode signal including an instruction to the functional modules to switch the elements of the vehicle to a restricted operating mode in relation to the confirmed fault signal or signals detected.

Abstract: A method and device for coupling an electric motor shaft with a wheel shaft of a vehicle includes measurement of rotation speed of the electric motor and measurement of rotation speed of the wheels. The method also includes formulating via a closed-loop control a first operating setpoint for the electric motor based on the measured rotation speed of the electric motor and the measured rotation speed of the wheels; formulating a second operating setpoint based on the measured rotation speed of the wheels to which at least one coefficient is applied; controlling the operation of the motor around a final operating setpoint formulated based on adding together the first and second operating setpoints; and coupling, if the measured speed of the wheels to which the at least one coefficient is applied is equal to the measured speed of the motor, the electric motor shaft with the wheel shaft.
