METHOD FOR ASSISTING WITH HILL MANEUVERS

摘要

A method for assisting with hill maneuvers for a vehicle, including a propulsion unit connected to the drive wheels by a gearbox and a clutch or torque converter, and an assisted parking brake. In the method a threshold breakaway torque is determined as a function of longitudinal forces between the wheels of the vehicles and the ground. During a degraded operation, when a signal corresponding to a characteristic of the slope is received that cannot be used and/or when a computer does not have available a signal characteristic of an engaged gear ratio, a threshold value for the breakaway torque is determined without taking account of an actual value of the characteristic of the slope and/or of the characteristic of the gear ratio.
