A method for determining a corrected yaw rate for a vehicle includes receiving a first yaw rate input from a yaw rate sensor of the vehicle and determining if the vehicle is moving or stationary. If the vehicle is determined to be moving, the method includes determining a steering angle of the vehicle, and determining an offset correction value based at least in part on a determined speed of the vehicle and the determined steering angle. A yaw rate offset is determined based at least in part on the determined offset correction value and the received first yaw rate input. A second yaw rate input is received from the yaw rate sensor of the vehicle, and a corrected yaw rate value is determined based at least in part on the received second yaw rate input and the determined yaw rate offset.

The method of claim 1, wherein, if the vehicle is determined to be moving below a threshold speed and the steering angle is determined to be less than a threshold level, the yaw rate offset is not changed from a previously determined yaw rate offset. 4. The method of claim 1, wherein, if the vehicle is determined to be moving at a determined speed that is above a threshold speed or the steering angle is determined to be greater than a threshold level, the yaw rate offset is determined based at least in part on the determined speed or the determined steering angle. 5. The method of claim 1, wherein, if the vehicle is determined to be moving at a determined speed that is above a threshold speed and the steering angle is determined to be greater than a threshold level, the yaw rate offset is determined based at least in part on the determined speed and the determined steering angle. 6. The method of claim 1, wherein determining the offset correction value is based at least in part on determination of lane markers on the road being traveled by the vehicle. 7.

The method of claim 13, wherein, if the vehicle is determined to be moving at a determined speed that is above the second threshold speed and the steering angle is determined to be greater than the second threshold level, the yaw rate offset is determined based at least in part on the determined speed and the determined steering angle. 16. The method of claim 13, wherein determining the offset correction value is based at least in part on determination of lane markers on the road being traveled by the vehicle. 17. The method of claim 13, wherein determining the yaw rate offset comprises using a first selected proportion of the received first yaw rate input and a second selected proportion of a previously determined yaw rate offset. 18. A method for determining a corrected yaw rate for a vehicle, said method comprising: receiving a first yaw rate input from a yaw rate sensor of the vehicle;determining, by a processor, if the vehicle is moving or stationary;if the vehicle is determined to be moving, determining a steering angle of the vehicle;determining, by the processor, an offset correction value based at least in part on a determined speed of the vehicle and the determined steering angle;determining lane markers on the road being traveled by the vehicle via processing of image data captured by a vehicle-mounted camera;wherein determining the offset correction value is based at least in part on determination of lane markers on the road being traveled by the vehicle;determining, by the processor, a yaw rate offset based at least in part on the determined offset correction value and the received first yaw rate input;receiving a second yaw rate input from the yaw rate sensor of the vehicle; anddetermining, by the processor, a corrected yaw rate value based at least in part on the received second yaw rate input and the determined yaw rate offset. 19.
