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.
