Actuator arrangement for a motor vehicle drive train and method for operating an actuator arrangement
First Claim
1. Actuator arrangement for a motor vehicle drive train, havinga control device,a monitoring device,an actuator,a drive circuit for the actuator, anda power stage arranged between the drive circuit and the actuator,the drive circuit receives at least one nominal signal relating to the actuator from the control device and converts it into a drive signal for the actuator,the control device is checked for control device faults by means of the monitoring device, wherein at least one of the drive circuit and the power stage receives a reset signal when such a control device fault occurs,the control device checks the function of the drive circuit and generates a reset signal for at least one of the drive circuit and the power stage if a drive circuit malfunction occurs, wherein the control device receives a first control signal from the actuator and checks the first control signal to determine whether the drive circuit is functioning correctly, and wherein the control device receives a second control signal from the drive circuit and evaluates the first control signal and the second control signal to determine whether the drive circuit is functioning correctly.

Abstract
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.
