    Abstract: A vision system for a vehicle includes a camera disposed at or proximate to an in-cabin portion of a windshield of the vehicle. The camera has a forward field of view to the exterior of the vehicle through the windshield of the vehicle. The camera is operable to capture image data. A control includes an image processor that is operable to process captured image data to determine lane delimiters present in the field of view of the camera. The control connects to a vehicle communication bus of the vehicle and receives vehicle data via the vehicle communication bus. Responsive at least in part to processing of captured image data by the image processor and to vehicle data received via the vehicle communication bus, the control determines a yaw rate. The control provides the determined yaw rate to a driver assistance system of the vehicle.

    Abstract: A control system or method for a vehicle references a camera and sensors to determine when an offset of a yaw rate sensor may be updated. The sensors may include a longitudinal accelerometer, a transmission sensor, a vehicle speed sensor, and a steering angle sensor. The offset of the yaw rate sensor may be updated when the vehicle is determined to be stationary by referencing at least a derivative of an acceleration from the longitudinal accelerometer. The offset of the yaw rate sensor may be updated when the vehicle is determined to be moving straight by referencing at least image data captured by the camera. Lane delimiters may be detected in the captured image data and evaluated to determine a level of confidence in the straight movement. When the offset of the yaw rate sensor is to be updated, a ratio of new offset to old offset may be used.
