Patent ID: 8204661

Claim:
A method of operating an electric brake system in different power consumption modes, the method comprising: operating the electric brake system in a full power mode corresponding to a first maximum brake performance capability, said full power mode powering all operational actuators, said full power mode comprising all of said operational actuators independently actuated with respect to at least one wheel to achieve 100 percent braking clamping force potential; detecting a condition that triggers a reduced power mode for the electric brake system; in response to said detecting switching from the full power mode to the reduced power mode, said reduced power mode powered only by a back-up power supply, said reduced power mode comprising powering said operational brake actuators with lower power consumption compared to said full power mode; and while in the reduced power mode, operating the electric brake system in a low power mode comprising a second maximum brake performance capability that is less than the first maximum brake performance capability.
