Abstract:
A vehicle stability control apparatus, comprising:a yaw rate sensor to detect a yaw rate of a vehicle;a physical amount detector to detect a physical amount input in the vehicle;a yaw momentum control apparatus to control yaw momentum of the vehicle in response to a control signal; anda control unit operatively coupled with the yaw rate sensor, the physical amount detector, and a yaw momentum control apparatus; whereinthe control unit calculates a first desired yaw rate for the vehicle from the physical amount;the control unit sets the first desired yaw rate as a desired yaw rate;the control unit judges that the vehicle is in an emergency evasion condition when the difference between the yaw rate and the first yaw rate is larger than a first value;the control unit sets 0 or nearly 0 as a desired yaw rate when the control unit judges that the vehicle is in the emergency evasion condition; andthe control unit applies the control signal to the yaw momentum control apparatus to reduce the difference between the yaw rate and the desired yaw rate.
