Abstract
An object-presence alert is given to a driver by a vehicular side-object detection system in response to a remote sensor for sensing objects in a predetermined zone of interest along side a vehicle. The zone of interest includes a front region and a rear region, and the remote sensor provides sensor data to generate a set of localized detection points. When detection points are sensed in the zone of interest, then a plurality of respective sets of detection points are collected at successive sample times. For each of the sets of detection points, a tracking type of the object within the zone of interest is determined in comparison to a speed of the vehicle and the object is classified as either a moving vehicle or a stationary object in response to the tracking type and in response to locations of the detection points in the zone of interest. If the object first appeared in a region other than the front region, then a short observation period is selected including a first predetermined number of sets of detection points and otherwise a long detection period is selected including a second predetermined number of sets of detection points longer than the first predetermined number. A number of times that the object is classified as a moving vehicle within the selected observation period is compared to a predetermined percentage threshold and the alert is initiated if classified as a moving vehicle for greater than the predetermined percentage threshold.
