Abstract:
A method of stabilizing a vehicle is provided. The vehicle is travelling at a forward speed and a lateral speed, and comprises a lateral acceleration sensor, a yaw sensor adapted to detect an actual yaw rate of the vehicle around a central axis, a steering mechanism adapted to steer the vehicle by a steered yaw rate, and an electronic stability control system. The method comprises determining the forward speed of the vehicle with the electronic stability control system, determining a yaw error rate based upon a difference between the actual yaw rate of the vehicle and the steered yaw rate, determining the vehicle is in an unstable condition by comparing the yaw error rate to a first predetermined yaw rate, computing a calculated lateral speed based on acceleration data from the lateral acceleration sensor, the forward speed, and the actual yaw rate in response to determining the vehicle is in the unstable condition, calculating a correction factor based on the calculated lateral speed of the vehicle and the forward speed of the vehicle, and adjusting operation of the electronic stability control system by the correction factor.
