Classification: B60T

Abstract:
A yaw moment control system in a vehicle, comprising:torque distributing means for distributing torque between left and right wheels of the vehicle;longitudinal acceleration calculating means for calculating the longitudinal acceleration of the vehicle;lateral acceleration calculating means for calculating the lateral acceleration of the vehicle;torque distribution amount determining means for determining the amount of torque distributed in a direction to inhibit the turning of the vehicle in accordance with a calculated longitudinal acceleration and a calculated lateral acceleration;a steering angle sensor for sensing the steering angle of the vehicle;a yaw rate sensor for sensing the yaw rate of the vehicle;a lateral acceleration sensor for sensing the lateral acceleration of the vehicle; whereinwhen said longitudinal acceleration calculating means calculates a positive longitudinal acceleration, said lateral acceleration calculating means calculates the lateral acceleration in accordance with an output from said steering angle sensor, and when said longitudinal acceleration calculating means calculates a negative longitudinal acceleration, said lateral acceleration calculating means calculates the lateral acceleration in accordance with an output from at least one of said yaw rate sensor and said lateral acceleration sensor.
