Abstract: A method is disclosed for improved target grouping of sensor measurements in an object detection system. The method uses road curvature information to improve grouping accuracy by better predicting a new location of a known target object and matching it to sensor measurements. Additional target attributes are also used for improved grouping accuracy, where the attributes includes range rate, target cross-section and others. Distance compression is also employed for improved grouping accuracy, where range is compressed in a log scale calculation in order to diminish errors in measurement of distant objects. Grid-based techniques include the use of hash tables and a flood fill algorithm for improved computational performance of target object identification, where the number of computations can be reduced by an order of magnitude.

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 controlling an adaptive cruise control feature of a vehicle are provided. In accordance with one embodiment, a system includes a sensing unit and a processor. The sensing unit is configured to detect passengers, other than a driver, in a vehicle. The processor is coupled to the sensing unit. The processor is configured to at least facilitate controlling an adaptive cruise control feature of the vehicle using a first profile if no passengers are detected in the vehicle, and a second profile, different from the first profile, if one or more passengers are detected in the vehicle.
