Claim 0:
1. A brake system for selectively actuating at least one of a pair of front wheel brakes and a pair of rear wheel brakes of a vehicle, a selected pair of the front wheel brakes and the rear wheel brakes being hydraulically actuated and an other pair of the front wheel brakes and the rear wheel brakes being electrically actuated, the system comprising:
a reservoir;
a pair of brake motors for selectively electrically actuating respective left and right wheel brakes of the pair of electrically actuated wheel brakes;
a first integrated control unit, in fluid communication with the reservoir and a selected one of the hydraulically actuated wheel brakes, the first integrated control unit having a first power transmission unit connected to a first electronic control unit, the first power transmission unit being configured to selectively generate pressurized hydraulic fluid for actuating the selected one of the hydraulically actuated wheel brakes during a braking event, the first electronic control unit being configured to control the first power transmission unit and a selected one of the electrically actuated wheel brakes, on a contralateral side of the vehicle from the selected one of the hydraulically actuated wheel brakes which is actuated by the first power transmission unit; and
a second integrated control unit, in fluid communication with the reservoir and an other one of the hydraulically actuated wheel brakes, the second integrated control unit having a second power transmission unit connected to a second electronic control unit, the second power transmission unit being configured to selectively generate pressurized hydraulic fluid for actuating the other one of the hydraulically actuated wheel brakes during a braking event, the second electronic control unit being configured to control the second power transmission unit and an other one of the electrically actuated wheel brakes, on a contralateral side of the vehicle from the other one of the hydraulically actuated wheel brakes which is actuated by the second power transmission unit, wherein the first and second electronic control units operate at the same time to control at least one of hydraulically actuating and electrically actuating the wheel brakes.
