Abstract: A method of releasing brakes of a motor vehicle including: if no vehicle start command takes place, after manual application of the vehicle brakes in a position to immobilize the vehicle when at rest is over, an assistance device progressively releases the brakes according to a suitable control scheme configured to make the vehicle move under its own weight, generally tending towards predetermined non-zero speed and acceleration conditions, and then, when the predetermined conditions are considered to have been reached, the assistance device stops releasing the brakes.

Abstract: A method for assisting a motor vehicle with a hill start, the motor vehicle having previously been held stationary when parked by a brake. The method measures inclination of the vehicle, previously establishes a map between engine torque and engine speed, defines, within the map, an authorized zone and a forbidden zone, provides a vehicle engine speed value, provides a vehicle engine torque value, deduces from these coordinates of the engine operating point within the map, and releases the brake automatically only if the coordinates of the operating point lie within the authorized zone of the map.

Abstract: A method for hill start assistance for a motor vehicle and to an associated device that includes a clutch and a transmission between the clutch and driving wheels of the vehicle. The method determines the torque of the clutch for maintaining the vehicle in an immobile position based on a known engine torque, wherein the torque of the clutch is determined by taking into account a portion of the engine torque dedicated to operation of constituent mechanisms of the vehicle other than the clutch.

Abstract: A driving method considering driving situations using at least one effective control signal of a member or group of members of an automobile, the method: making an arbitration between different control strategies each corresponding to a driving context, each control strategy being marked with an identifier continuously calculating an optimal control signal corresponding to each of the strategies; continuously transmitting a value representative of the identifier of the selected strategy; detecting if a strategy identifier change has occurred; when a change is detected, generating a time function x(t) increasing from 0 to 1 over a finite time interval starting when the strategy change has been detected; when a strategy identifier change has been detected, transmitting, during at least one time interval following the identifier change, an effective control signal which is the sum of the optimal signal of the control strategy following the last identifier change weighed by the value x(t) and of the optimal signa
