設けてなることを特徴とする車両用制動装置。[Scope of Claim for Utility Model Registration] When the brake pedal 1 is operated, the fluid pressure generated in the master cylinder 3 is applied to each wheel cylinder 5, 6 for the front wheel brake and the rear wheel brake.
The master cylinder 3 and the wheel cylinders 5 and 6 are connected to a fluid communication passage 15 so as to be transmitted to the master cylinder 3 and the wheel cylinders 5 and 6.
, 16, and is configured such that the break point pressure of the brake distribution line can be arbitrarily set by driving the break point setting member 41 by the external actuator 9. A valve 4 is disposed between the master cylinder 3 and the rear brake wheel cylinder 6, and a load sensor 7 for detecting the load applied to the rear axle 17 is further provided. A control unit 8 is provided for calculating an optimum corner pressure value of the variable corner setting type proportioning valve 4 according to the rear wheel axle load, and the external actuator 9 is controlled based on the calculation result of the control unit 8. In the vehicle braking system, the corner point pressure value of the corner point setting variable proportioning valve 4 is controlled to be an optimum value commensurate with the rear wheel axle load. A sensor 13 is provided, and when the acceleration sensor 13 detects that a sudden acceleration/deceleration is applied to the vehicle, the corner point pressure value of the variable corner point setting type proportioning valve 4 is set to detect a sudden acceleration/deceleration on the vehicle. A braking device for a vehicle, characterized in that it is provided with a function of controlling the speed so that it is maintained at the value immediately before the braking device is applied.
