ABSTRACT:
A motor vehicle includes a drive system consisting of an engine and an electrohydraulically actuatable automatic transmission connected to the vehicle body by resilient mounts. To reduce stationary vibration of the vehicle and engagement and disengagement shock, the engagement pressure of a clutch in the transmission is controlled so that the clutch begins to slip when the strain between the drive system and the vehicle body reaches a selected value. The strain is determined by detecting the displacement of the drive system with respect to the body or the torque in the drive system or the stress in the resilient mounts.
