Abstract
An electro-hydraulic brake-by-wire system includes a brake pedal, an electronic booster coupled to the brake pedal, a master cylinder coupled to the electronic booster, at least one front hydraulic brake disposed in fluid communication with the master cylinder, at least one electronic control unit connected to the brake pedal and at least one rear electronic brake connected to the at least one electronic control unit.
Claims20
An electro-hydraulic brake system, comprising:
- a brake pedal;
- an electronic booster coupled to said brake pedal and connected to at least one electronic control unit;
- a master cylinder coupled to said electronic booster;
- at least one front hydraulic brake disposed in fluid communication with said master cylinder;
- said at least one electronic control unit connected to said brake pedal;
- at least one rear electronic brake connected to said at least one electronic control unit;
- and
- wherein said at least one electronic control unit is configured to actuate said electronic booster and said at least one rear electronic brake in response to sensed brake pedal travel and wherein said at least one electronic control unit is further configured to actuate at least one of said electronic booster and said at least one rear electronic brake independent of said sensed travel of said brake pedal, said at least one electronic control unit further configured to independently control braking pressure applied to each of said at least one rear electronic brake and said at least one front hydraulic brake.

A vehicle, comprising:
- a chassis;
- a front axle and a rear axle carried by said chassis;
- a front pair of wheels and a rear pair of wheels carried by said front axle and said rear axle, respectively;
- a drive mechanism drivingly engaging at least one of said front axle and said rear axle;
- and
- an electro-hydraulic brake system comprising:
- a brake pedal;
- an electronic booster coupled to said brake pedal and connected to at least one electronic control unit;
- a master cylinder coupled to said electronic booster;
- at least one front hydraulic brake disposed in fluid communication with said master cylinder and adapted to engage at least one of said front pair of wheels;
- said at least one electronic control unit connected to said brake pedal;
- at least one rear electronic brake connected to said at least one electronic control unit and adapted to engage at least one of said rear pair of wheels;
- and
- wherein said at least one electronic control unit is configured to actuate said electronic booster and said at least one rear electronic brake in response to sensed brake pedal travel and wherein said at least one electronic control unit is further configured to actuate at least one of said electronic booster and said at least one rear electronic brake independent of said sensed travel of said brake pedal, said at least one electronic control unit further configured to independently control braking pressure applied to each of said at least one rear electronic brake and said at least one front hydraulic brake.

A method of operating an electro-hydraulic brake-by-wire system, comprising:
- providing a vehicle having a pair of hydraulic front brakes and a pair of electronic rear brakes, at least one electronic booster connected to at least one of said pair of hydraulic front brakes, a brake pedal coupled to said at least one electronic booster, at least one electronic control unit connected to said brake pedal and to said at least one electronic booster and at least one of said pair of electronic rear brakes connected to said at least one electronic control unit;
- configuring said at least one electronic control unit to actuate said electronic booster and said pair of electronic rear brakes in response to sensed brake pedal travel and further configuring said at least one electronic control unit to actuate at least one of said electronic booster and said at least one rear electronic brake independent of said sensed travel from said brake pedal, said at least one electronic control unit further configured to independently control braking pressure applied to each of said at least one rear electronic brake and said at least one front hydraulic brake;
- operating said vehicle;
- applying pressure to said brake pedal;
- actuating said hydraulic front brakes;
- and
- actuating said electronic rear brakes.
