Abstract
A vision system for a vehicle includes a camera having a forward field of view to the exterior of the vehicle through the vehicle windshield. 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 and receives vehicle data via a vehicle communication bus. The vehicle data includes a yaw rate sensed by a yaw rate sensor of the vehicle. 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 corrected yaw rate at least one of (i) when the vehicle is stationary and (ii) when the vehicle is moving straight. The control provides the corrected yaw rate to a driver assistance system of the vehicle.
