Anti-skid control system for automotive vehicle
First Claim
1. An anti skid control system for an automotive vehicle comprising:
- means provided independently for each wheel of the vehicle, for controlling brake fluid pressure on each wheel in response to a control signal;
means for detecting a vehicle speed and a rotation speed of said wheel and deriving slip ratio of said wheel on the basis of the detected values;
means for detecting actual yawing angular acceleration on the vehicle;
setting means for setting a target value of the slip ratio on the wheel based on said yawing angular acceleration for each wheel independently of the other; and
control signal means for providing said control signal to said brake fluid pressure controlling means so as to adjust the derived slip ratio toward said target value.

Abstract
The invention relates to an anti-skid control system for an automotive vehicle, which includes devices provided independently for respective wheels of the vehicle and for controlling the brake fluid pressure of respective wheels, device for detecting a vehicle speed and a rotation speed of the wheel and deriving slip ratio on the wheel on the basis of the detected values, device for detecting actual yawing angular acceleration on the vehicle, device for setting a target value of the slip ratio on the wheel based on the yawing angular acceleration for each wheel independently of the other, and control signal unit for providing the control signal to the brake fluid pressure controlling unit so as to adjust the derived slip ratio toward the target value.

21. An anti skid control method for an automotive vehicle comprising the steps of:
-
controlling brake fluid pressure on each wheel of the vehicle in response to a control signal by a brake fluid pressure controlling device; detecting a vehicle speed and a rotation speed of said wheel and deriving slip ratio on said wheel on the basis of the detected values; detecting actual yawing angular acceleration on the vehicle; setting a target value of the slip ratio on the wheel based on said yawing angular acceleration for each wheel independently of the other; and providing said control signal to said brake fluid pressure controlling device so as to adjust the derived slip ratio toward said target value.
