Antiskid braking device
First Claim
1. An antiskid braking device for braking a wheel of a vehicle, comprising:
- a brake pedal,a master cylinder that generates a pressure according to a depression amount of said brake pedal,a wheel cylinder that applies a braking force to said wheel according to the pressure of said master cylinder,means for detecting a rotation speed of said wheel,means for detecting a vehicle speed,means for detecting said braking force,means for computing a target decrease amount of said braking force based on said wheel speed and said vehicle speed,means for selecting a larger value of a predetermined minimum decrease amount and said target decrease amount, andmeans for decreasing said braking force according to the amount selected by said selecting means.

Abstract
In an antiskid braking system for increasing or decreasing a braking force according to a wheel speed and a vehicle speed, an algorithm applied to the determination of a braking force decrease amount is improved. Once a target braking force decrease amount is determined according to the wheel speed and vehicle speed, this is compared with a predetermined minimum decrease amount, and when the target decrease amount is less than the minimum decrease amount, braking force is decreased according to the minimum decrease amount. The minimum decrease amount is preferably determined according to the braking force immediately before the braking force decrease. In this way, braking force reduction insufficiencies in several conditions are prevented.
