ACTUATOR ARRANGEMENT FOR A MOTOR VEHICLE DRIVE TRAIN AND METHOD FOR OPERATING AN ACTUATOR ARRANGEMENT

摘要

An actuator arrangement for a motor vehicle drive train has a control device, an electric actuator and a drive circuit for the actuator. The drive circuit receives at least one nominal signal relating to an actuator from the control device and converts it into a drive signal for the actuator. The control device is checked for faults by means of a monitoring device. The drive circuit and/or a power stage which is arranged between the drive circuit and the motor receives a reset signal when such a fault occurs. Further, the control device is configured to check the function of the drive circuit and to generate a reset signal for the drive circuit and/or for the power stage if a malfunction occurs.
