Control system dependent on an error in the engine control system

Abstract

A device for controlling a driving force which is mounted between a vehicle motor and the wheels of a motor vehicle controls at least to reduce the force flow between the vehicle motor and the wheels in response to a drive signal. The vehicle motor is controlled by the device of a motor control. The drive signal is formed in dependence upon a detected fault in the motor control. The force flow between the vehicle motor and the wheels is especially then interrupted when an emergency shutoff of the motor can cause a high drag torque on the wheels and therefore a driving situation critical with respect to safety. The device for controlling the driving force is comprising a clutch downstream of the motor, an automatic or automated transmission, and a converter bridge clutch which can bridge the torque converter downstream of the vehicle motor.

Dependencies are inferred from the claim text.
