Metod och anordning för start i uppförsbacke

摘要

Method and arrangement for facilitating hill-starting of a stationary motor vehicle. The method includes applying at least one braking device using a brake pedal and estimating the traveling resistance of the vehicle using a control unit ( 30 ). The control unit ( 30 ) determines a starting gear, a starting torque and a starting speed with regard to the estimated traveling resistance. The driver releases the brake pedal and the brakes are kept applied for a certain time. The driver operates an accelerator pedal to a position at least corresponding to the minimum transmitted torque and a clutch device ( 2 ) for a gearbox ( 3 ) is activated by the control unit ( 30 ) when the starting speed has been achieved. The control unit ( 30 ) releases the braking devices as a function of the increase in the transmitted driving torque of the clutch.
