Abstract
A vehicle stability control method includes collecting steering information from a sensor of a vehicle, calculating a saturation index of a front axle of the vehicle or a rear axle of the vehicle using the steering information, and controlling an application of the vehicle based on the saturation index.
Claims10
A vehicle stability control method performed by a vehicle stability control apparatus, the method comprising:
- collecting steering information from a sensor of a vehicle;
- calculating a saturation index of a front axle of the vehicle or a rear axle of the vehicle using the steering information;
- and
- controlling an application of the vehicle based on the saturation index,
- wherein the calculating includes determining whether the front axle is saturated by using a slip angle and a slip angular velocity of a front wheel tire, and determining whether the rear axle is saturated by using a slip angle and a slip angular velocity of a rear wheel tire, and
- wherein the controlling includes controlling an Active Yaw Control (AYC) for adjustment between agility intervention and stabilizing intervention using the saturation index.

A vehicle stability control apparatus comprising:
- a data collector configured to collect steering information from a sensor of a vehicle;
- a calculator configured to calculate a saturation index of a front axle of the vehicle or a rear axle of the vehicle using the steering information;
- and
- a controller configured to control an application of the vehicle based on the saturation index,
- wherein the calculator is configured to determine whether the front axle is saturated using a slip angle and a slip angular velocity of a front wheel tire and whether the rear axle is saturated using a slip angle and a slip angular velocity of a rear wheel tire, and
- wherein the controller is configured to control an Active Yaw Control (AYC) for adjustment between agility intervention and stabilization intervention using the saturation index.

- and
- controlling an application of the vehicle based on the saturation index,
- wherein the calculating includes calculating the saturation index of the rear axle of the vehicle, and the controlling includes adjusting intervention of an Electronic Stability Control (ESC) or Rear Wheel Steering (RWS) based on the saturation index of the rear axle, and
- wherein the controlling includes controlling the RWS as a master actuator when the saturation index of the rear axle is lower than a reference index and controlling the ESC as the master actuator when the saturation index of the rear axle is higher than the reference index.
