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.

Method for assisting with hill starts

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.
