ABSTRACT:
A fail-operational control system utilizes low current switches for controlling vehicle high current loads. In a normal mode of operation, the control system utilizes a CPU to control the loads in response to input signals provided to the CPU by the low current switches. In a fail-operational mode of operation, during failure or removal of the CPU, certain high current loads are switched directly by corresponding low current switches to provide continued operation of the certain high current loads.
