Abstract

In one aspect of the present invention, a method for detecting an electrical fault condition of a driver circuit is disclosed. The driver circuit is used to energize an electrohydraulic device that regulates fluid pressure. The method detects the fault condition, and responsively switches from a normal fluid pressure control strategy to a fault mode fluid pressure control strategy in order to continue to control the fluid pressure during the fault condition.
