Abstract: A method and system are disclosed for tracking a remote vehicle which is driving in a lateral position relative to a host vehicle. Target data from two radar sensors are provided to an object detection fusion system. Wheels on the remote vehicle are identified as clusters of radar points with essentially the same location but substantially varying Doppler range rate values. If both wheels on the near side of the remote vehicle can be identified, a fusion calculation is performed using the wheel locations measured by both radar sensors, yielding an accurate estimate of the position, orientation and velocity of the remote vehicle. The position, orientation and velocity of the remote vehicle are used to trigger warnings or evasive maneuvers in a Lateral Collision Prevention (LCP) system. Radar sensor alignment can also be calibrated with an additional fusion calculation based on the same wheel measurement data.

Abstract: A method for monitoring performance of a navigation system onboard a vehicle is provided. The method obtains, at a vehicle electronic control unit (ECU), a triangulated vehicle location and vehicle motion data, the triangulated vehicle location obtained from the navigation system; computes an estimated vehicle location, using the triangulated vehicle location and the vehicle motion data; calculates a probability that the estimated vehicle location exists within an error bound of the triangulated vehicle location; and when the probability indicates that the estimated vehicle location does not exist within the error bound, performs a task onboard the vehicle.

Abstract: A method for assessing operation of a navigation system onboard a vehicle is provided. The method determines a sensor-based lateral offset change using vehicle onboard sensor data; determines a second lateral offset change using navigation system data; computes a difference between the sensor-based lateral offset change and the second lateral offset change; performs secondary calculations using the difference to produce a result; and when the result is greater than a threshold error value, provides an error notification.

Abstract: Methods and systems for determining a misalignment angle for a sensor in a vehicle are provided. The method, for example, may include, but is not limited to determining, by a processor, when an object detected in sensor data acquired by the sensor is a stationary object, and calculating, by the processor, the misalignment angle of the sensor based upon sensor data associated with the stationary object.
