Patent ID: 8874341

Claim:
An electronic brake actuator system, comprising: a brake pedal; an electronic booster mechanically coupled to said brake pedal by a pushrod, said electronic booster electrically driven; a master cylinder coupled to said electronic booster; at least one hydraulic brake circuit disposed in fluid communication with said master cylinder; at least one pair of front hydraulic brakes disposed in fluid communication with said at least one front hydraulic brake circuit; at least one pair of rear hydraulic brakes disposed in fluid communication with said at least one rear hydraulic brake circuit; an electronic control unit electrically connected to and configured to control said electronic booster via electrical inputs, said electronic control unit further operably connected to said at least one front and rear hydraulic brake circuits, said at least one front and rear hydraulic brake circuits configured to facilitate flow of hydraulic fluid through said at least one front hydraulic brake circuit to each of said at least one pair of front hydraulic brakes and through said at least one rear hydraulic brake circuit to each of said at least one pair of rear hydraulic brakes; a pedal travel or angle sensor directly mechanically coupled to said brake pedal, said pedal travel or angle sensor electrically connected to said electronic control unit, said pedal travel or angle sensor configured to transmit an activation signal to said electronic control unit, said electronic control unit configured to actuate said at least one pair of front hydraulic brakes and said at least one pair of rear hydraulic brakes through said respective front and rear hydraulic brake circuits responsive to said activation signal; a pedal feel simulator engaged by said brake pedal and electrically connected to said electronic control unit; and said electronic control unit further configured to actuate said electronic booster independent of travel from said brake pedal, wherein means is provided such that said brake pedal is mechanically decoupled from said pushrod and said electronic booster.
