Abstract: A method controls a power train of a vehicle immobilized in a parking position, the vehicle being provided with a parking brake device for immobilizing the vehicle and at least one electric motor. The method includes detecting the slope direction and/or slope data when the parking brake device is in an actuated position, detecting that the parking brake device has switched from the actuated position to a released position, and applying a motor torque setpoint to the electric motor in accordance with the detected slope direction and/or slope data.

Abstract: A method controls regenerative braking of a motor vehicle provided with an electric or hybrid powertrain. The method includes determining that a driver is pressing neither a throttle pedal nor a brake pedal of the vehicle. The method also includes determining a correction coefficient as a function of a torque supplied by a motor of the powertrain, of a speed and an angular velocity at a wheel of the vehicle, of a gradient, of a mass of the vehicle, and of friction. Next, the method includes determining a setpoint for regenerative braking without pressure on the brake pedal as a function of the correction coefficient and of two maps of torque as a function of a rotational speed of the powertrain, for a substantially zero gradient and a vehicle mass substantially equal to a reference mass of the vehicle.

Abstract: An engine control, and in particular a method for controlling an engine including a low-pressure exhaust gas recycling loop. The method adjusts a predetermined engine operating parameter by controlling the position of an exhaust gas recycling valve, which is placed in the loop, for determining whether the predetermined measured quantity of the valve respects a predetermined criteria, and controls the position of an exhaust shutter, which is arranged outside the loop, when the quantity does not respect the criteria.
