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.
Claims15
A method for efficiently decelerating a vehicle having a braking circuit for braking a set of brake actuators, the method comprising the steps of:
- (a) providing an electronic vehicle braking system having at least one brake circuit for supplying pressurized brake fluid to vehicle brake actuators, each of the brake actuators associated with a wheel brake;
- (b) sensing braking forces being applied to the wheels associated with the vehicle brake actuators during a bake activation;
- (c) comparing the sensed forces;
- (c) isolating the brake actuator associated with the lowest braking force with at upon detection of a need for rapid vehicle speed reduction;
- and
- (c) generating a flow of pressurized brake fluid for the brake actuators associated with the non-isolated vehicle brakes.

A vehicle stability control system for efficiently decelerating a vehicle, the vehicle stability control system comprising:
- a braking circuit for braking a set of brake actuators coupled to a set of wheels that include front and rear vehicle wheels;
- 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 senor 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 the brake actuators associated with the front vehicle wheels.
