Abstract
The present invention relates to an apparatus and method for controlling vehicle motion. More specifically, the invention relates to an apparatus for improving vehicle stability by controlling the brake torque of a vehicle during, for example, cornering manuevers. In accordance with the present invention, vehicle stability is improved by independently controlling brake torque in response to sensed yaw rate.
Claims14
An apparatus for controlling a vehicle comprising:
- means responsive to the influence of destabilizing forces on a vehicle for measuring an actual yaw rate of said vehicle;
- means for determining a dynamically variable target yaw rate of said vehicle and for producing an output signal in response to a comparison of said target yaw rate and said actual yaw rate;
- and,
- brake controlling means, responsive to said output signal, for maintaining stability of the vehicle when said vehicle is in motion.
1 more element
A method for controlling vehicle motion comprising the steps of:
- detecting an actual yaw rate of a vehicle;
- determining a dynamically variable target yaw rate of said vehicle;
- comparing said actual yaw rate with said target yaw rate to produce an output;
- and,
- maintaining vehicle stability in response to said output signal during an influence of lateral forces on said vehicle.

An apparatus for controlling vehicle motion comprising:
- means for measuring an actual yaw rate of a vehicle;
- means for determining a dynamically variable target yaw rate of said vehicle;
- means responsive to said measuring means and said determining means for producing an output signal in response to a comparison of said target yaw rate and said actual yaw rate;
- and
- brake controlling means, responsive to said output signal, for maintaining vehicle stability at least partially in response to said output signal.
