Abstract
A vehicular control system includes a camera, a yaw rate sensor, wheel sensors, an accelerometer and a steering sensor. A control includes a processor that estimates the actual yaw rate of the vehicle based on (a) a first yaw rate derived from yaw rate data provided by the yaw rate sensor, and (b) at least one selected from the group consisting of (i) a second yaw rate derived from wheel sensor data provided by the wheel sensors, (ii) a third yaw rate derived from acceleration data provided by the accelerometer, and (iii) a fourth yaw rate derived from steering data provided by the steering sensor. The vehicular control system at least in part controls the vehicle based on (i) image data captured by the camera as the vehicle travels along a road and (ii) the estimated actual yaw rate of the vehicle.
