摘要：
An environmental sensing system relating to vehicle lane position includes first and second sensors respectively configured to provide first and second signals indicative of a vehicle lane position. A steering system achieves a desired lane position in response to a command from a controller to keep the vehicle in its lane, for example, during autonomous control of the vehicle. The controller uses the first signal if the first sensor provides a desired lane marker confidence. The controller switches to the second sensor and uses the second signal if the first sensor cannot provide the desired lane marker confidence and the second sensor can provide the desired lane marker confidence.
