Abstract
Method of aiding shifting operations in motor vehicles with automated manual or automatic transmissions. The current operating conditions are detected and analyzed in an analyzing unit. In the event of an operation of the motor vehicle which indicates an imminent shifting operation, a precontact switch, which is arranged in an operating device for the gear selection, switches into an active mode. This precontact switch emits a signal when the driver approaches to grip the operating device for the gear shifting. In the event of the occurrence of the precontact switch signal, the shifting operation is initiated by a reduction of the engine torque while the driver has not yet gripped the operating device. This clearly shortens the shifting time.
