Braking force control system for an automotive vehicle
First Claim
1. A braking force control system for an automotive vehicle comprising:
- braking means for applying a braking force to each of front and rear wheels of said vehicle at least in response to depression of a brake pedal;
desired yaw rate setting means for setting a desired yaw rate in accordance with a motion of said vehicle;
actual yaw rate measuring means for measuring an actual yaw rate of said vehicle;
first varying rate calculation means for calculating a varying rate of the desired yaw rate set by said desired yaw rate setting means;
second varying rate calculation means for calculating a varying rate of the actual yaw rate measured by said actual yaw rate measuring means;
deviation calculation means for calculating a deviation between the varying rate of the desired yaw rate and the varying rate of the actual yaw rate; and
limitation means for actuating said braking means to limit the varying rate of the actual yaw rate by applying the braking force to at least one of said wheels, when the deviation calculated by said deviation calculation means exceeds a predetermined value.

Abstract
The present invention is directed to a braking force control system for an automotive vehicle having a hydraulic braking pressure control apparatus which is provided for applying the braking force to each of front and rear wheels of the vehicle at least in response to depression of a brake pedal. A desired yaw rate is set in accordance with a motion of the vehicle, and an actual yaw rate of the vehicle is measured. A varying rate of the desired yaw rate is calculated, and a varying rate of the actual yaw rate is calculated. Then, a deviation between the varying rate of the desired yaw rate and the varying rate of the actual yaw rate is calculated. And, a limitation unit is provided for actuating the hydraulic braking pressure control apparatus to limit the varying rate of the actual yaw rate by applying the braking force to at least one of the wheels, when the deviation exceeds a predetermined value. The limitation unit may be so constituted as to apply the braking force to a front wheel of the wheels which is located on the outside of a curve in the vehicle'"'"'s path.
