Abstract:
A vehicle active brake control having sensors for detecting vehicle speed and a driver steering input, wherein the control differentially brakes the vehicle wheels to impart a commanded yaw to the vehicle, the improvement wherein the commanded yaw is determined according to a method comprising the steps of:determining a desired yaw rate as a function of the detected vehicle speed and driver steering input;determining a first yaw command component in proportion to the desired yaw rate when such desired yaw rate is outside a first predefined dead-band window, said first yaw command component being limited to a first saturation threshold outside said first dead-band window;determining a second yaw command component in proportion to a rate of change of said desired yaw rate when such rate of change is outside a second predefined dead-band window, said second yaw command component being limited to a second saturation threshold outside said second dead-band window;summing said first and second yaw command components to form said commanded yaw.
