Title: Front and rear distribution control device for vehicle brake force
Inventor: MATSUDA TOSHIRO
IPC: B60T8/28
Filed: 1990-12-21
Abstract: PURPOSE:To prevent the occurrence of under-steering tendency during a vehicle's turn under a strong brake force, or oversteering tendency during the turn under a weak brake force by controlling the brake force for distribution to front and rear wheels. CONSTITUTION:A controller 18 causes an increase in the set load (split point of fluid pressure control valve 6) of a pressure regulation spring 10 via the operation of a motor 17, according to the state of turning, when the turn of a vehicle is detected with a lateral acceleration sensor 20. Brake fluid pressure is thereby distributed to front and rear wheels, so that the rear wheel is locked before the front wheel under the application of a strong brake force, thereby correcting under-steering tendency. Also, the controller 18 causes a drop in the set load of the spring 10 via the operation of the motor 17, while a brake force detected with a longitudinal acceleration sensor 21 is weak. As a result, brake fluid pressure is distributed to the front and rear wheels, so that the front wheel is locked before the rear wheel via a drop in the aforesaid split point, thereby correcting over-steering tendency. According to this construction, the locus of the vehicle's turn under a brake force can be properly maintained.
