Method for assisting the start-up of a vehicle on a slope with hill-start assistance system

摘要

A method for assisting start-up on a motor-driven vehicle having a start-stop system and a hill-start assistance system (HSA) and automatic transmission or automated clutch, comprising the steps of: Braking the vehicle in motion by actuating a brake pedal controlling a brake device on an incline, - the engine is switched off by the start-stop system as soon as the vehicle is at a standstill when the brake pedal is actuated, Inserting an idling stage (N) before or after the vehicle is at a standstill with the engine stopped and the braking device actuated by the start-stop system, The engine is started by the start-stop system as soon as the brake pedal is released when the vehicle is at a standstill and the idling step (N) is engaged, in which - If the hill hold assist system (HSA) fails to take action, a brake lever is temporarily held within the braking device at a standstill of the vehicle within the brake device by actuating the brake pedal at least with the brake pressure built up temporarily for a defined holding period (HT) to keep the vehicle at a standstill on the slope.
