Abstract

The present invention provides driveaway assistance for a motor vehicle having braking equipment which, in the standstill condition of the motor vehicle, automatically or under the control of a vehicle driver summons up braking forces needed for the standstill condition. To assist start-up (driveaway) of the motor vehicle through a reduction of the braking forces generated in the standstill condition, a driveaway request or a vehicle driver is determined when defined conditions, which are to be met for driveaway of the motor vehicle, exist in the standstill condition. Once a driveaway request has been recognized, the operating state of the motor vehicle is checked until an operating condition required for driveaway exists. Once such an operating condition is reached, the braking equipment of the motor vehicle is controlled in such a way that its braking forces generated in the standstill condition are reduced to allow driveaway of the vehicle.
