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.

Abstract: A control device for a vehicle comprising: a sensor that acquires information on a driving direction and a speed of the vehicle; a first calculator that calculates a slip angle of front wheels and a slip angle of rear wheels of the vehicle based on the information acquired by the sensor; a second calculator that calculates a saturation index of the front wheels and a saturation index of the rear wheels using a phase plane related to the slip angle of the front wheels and the slip angle of the rear wheels; and a controller that distributes traction torque to a front wheel axle and a rear wheel axle based on the phase plane and the saturation index of the front wheels and the saturation index of the rear wheels.

Abstract: A vehicle having two forwardly positioned steerable road wheels and first and second rearwardly positioned wheels disposed on opposing lateral sides of the vehicle has first and second independently controllable electric motors to apply driving and braking torque to respective rearwardly positioned wheels. An angle sensor indicates a steering angle of the steerable road-wheels, and a speed sensor indicates vehicle longitudinal speed. A yaw-rate sensor indicates the vehicle's measured yaw-rate. The vehicle has control means to determine a target yaw-rate from the steering angle of the steerable road wheels and the longitudinal velocity; determine a yaw rate error by comparing the vehicle's measured yaw-rate with said target yaw-rate, and determine an amount of yaw torque to correct or reduce the yaw-rate error; and control the electric motors to apply an amount of differential torque to the respective first and second rearwardly positioned wheels to generate said amount of yaw torque.

Abstract: A vehicle with at least two forwardly positioned steerable road wheels and at least first and second rearwardly positioned wheels disposed on opposing lateral sides of the vehicle is provided with first and second electric motors adapted to apply driving and braking torque to the respective rearwardly positioned wheels. The first and second electric motors are independently controllable. At least one angle sensor is configured to provide an output indicative of a steering angle of the steerable road-wheels. At least one speed sensor configured to provide an output indicative of the vehicle longitudinal speed. A vehicle yaw-rate sensor is configured to provide an output indicating the vehicle's measured yaw-rate.
