Abstract
A system and method for providing fault mitigation in a vehicle system having high side drivers (HSDs) and low side drivers (LSDs) are provided. The system includes a first HSD and a plurality of first LSDs. The system also includes a selected first plurality of actuators, with each actuator connected to the first HSD and connected to a respective one of the first LSDs to operate in a first operational mode. The system further includes a second HSD and a plurality of second LSDs. The system also includes a selected second plurality of actuators, with each actuator connected to the second HSD and connected to a respective one of the second LSDs to operate in a second operational mode. When a failed component sets a fault, the corresponding HSD is turned off and the other HSD is turned on, enabling the vehicle system to operate in the non-faulted operational mode.
