  • Method of braking force distribution control for a vehicle hydraulic device
    Patent number: 6280003
    Abstract: It is an object of this invention to provide a method for when and on which wheel to initiate braking force distribution. In a brake hydraulic device for a motor vehicle, a rear wheel subject to control is an inner or outer wheel is checked; if the outer wheel is to be controlled, deceleration threshold value is increased according to the lateral acceleration, and if the absolute value of the vehicle deceleration exceeds the deceleration threshold value, the braking distribution control is operated on the rear wheel; and if the inner wheel is to be controlled, deceleration threshold value is decreased according to the lateral acceleration, and if the absolute value of vehicle deceleration exceeds the deceleration threshold value, the braking distribution control is operated on the rear wheel.

  • Braking force distribution control system and method
    Patent number: 6276767
    Abstract: A system and method for initiating a braking force distribution control are disclosed. In one embodiment the deceleration of a front wheel and rear wheel are determined. When the front wheel deceleration is less than the rear wheel deceleration, the braking force distribution control is initiated.
