Abstract
A method for efficiently decelerating a vehicle having front and rear wheel brakes by isolating the rear wheel brakes and applying pressurized brake fluid only to the front wheel brakes.
Claims16
A method for decelerating a vehicle comprising the steps of:
- (a) providing a hydraulic braking system having at least one brake circuit for supplying pressurized brake fluid to vehicle brake actuators that are each associated with a wheel brake;
- (b) sensing braking forces being applied to each of the wheels by the vehicle brake actuators during a brake activation;
- (c) comparing the sensed braking forces;
- (d) isolating the vehicle brake actuator associated with a lowest braking force upon detection of a need for rapid vehicle speed reduction;
- and
- (e) generating a flow of pressurized brake fluid to the non-isolated vehicle brake actuator.

A method for decelerating a vehicle comprising the steps of:
- (a) providing a hydraulic braking system having at least one brake circuit for supplying pressurized brake fluid to front and rear vehicle brake actuators associated with respective front and rear brakes, wherein an output of the front brakes is higher than an output of the rear brakes;
- (b) isolating the rear vehicle brake actuator upon detection of a need for rapid vehicle speed reduction;
- and
- (c) generating a flow of pressurized brake fluid to the front vehicle brake actuator.

A vehicle stability control system for decelerating a vehicle, the vehicle stability control system comprising:
- a braking circuit for braking a set of brake actuators associated with respective front and rear brakes coupled to a set of wheels that include respective front and rear vehicle wheels, wherein an output of the front brakes is higher than an output of the rear brakes;
- a brake fluid pressurization system coupled to said braking circuit;
- a brake control module for controlling hydraulic pressure to each brake actuator;
- at least one sensor for generating a signal indicative of a need for rapid vehicle speed reduction;
- and
- a controller for the brake fluid pressurization system, the controller connected to the at least one sensor and operative, upon receiving a signal indicative of a need for rapid vehicle speed reduction, to first isolate the brake actuators associated with the rear vehicle wheels and then to apply pressurized brake fluid to the brake actuators associated with the front vehicle wheels.
