Vehicle braking control system

摘要

A vehicle braking control system includes a wheel cylinder which applies a braking force in accordance with a fluid pressure to a vehicle wheel and a control device which controls the fluid pressure of the wheel cylinder based on the vehicle wheel acceleration. Then, the control device applies the predetermined fluid pressure to the wheel cylinder so as to acquire a return level of the vehicle wheel acceleration and calculates a control target value of the fluid pressure based on a behavior of the vehicle wheel acceleration after starting a sudden braking operation and before starting ABS control.

1. A vehicle braking control system comprising:
wheel cylinders configured to apply a braking force in accordance with a fluid pressure to vehicle wheels; and a control device configured to control the fluid pressure of the wheel cylinders based on a vehicle wheel acceleration, wherein when a change amount of the vehicle wheel acceleration is called a return level of the vehicle wheel acceleration while maintaining the fluid pressure of the wheel cylinders or increasing the fluid pressure at a predetermined gradient, the control device obtains the return level of the vehicle wheel acceleration while maintaining or increasing the fluid pressure of the wheel cylinders after starting a sudden braking operation and before starting an antilock brake control, and calculates a control target value of the fluid pressure based on the return level of the vehicle wheel acceleration.
