Abstract
An apparatus for measuring the yaw rate of a vehicle, comprising a device for measuring the velocity of the vehicle, a device for measuring the lateral acceleration of the vehicle, and a device for measuring the steering angle of the vehicle, a correction device, and a yaw gyrometer. The correction device acts to remove bias errors from the output of the yaw gyrometer. The correction device also estimates the bias errors when the velocity of the vehicle is within a tolerance of zero or when both the steering angle of the vehicle is within a tolerance of zero and the lateral acceleration of the vehicle is within a tolerance of zero.
