Abstract
An actuator controller to controllably supply DC power to a bi-directional electromechanical actuator is provided. The controller includes a first circuit to receive power and direction command signals from a remote electronic control unit through a vehicle-based bus. Control logic is operative to determine a vehicle system failure and to generate a failsafe position command signal in the event of the failure. A failsafe power circuit controllably stores electrical power and supplies the stored electrical power based on the failsafe position command signal. A power switching and supply circuit supplies DC power of a desired polarity to the electromechanical actuator in response to the power and direction command signals in the absence of the failure and supplies the stored electrical power to the electromechanical actuator in the event of the failure.
