Abstract
A detection system includes a ranging sensor and a controller circuit. The ranging sensor is configured to detect range rates of objects proximate a host vehicle. The controller circuit is in communication with the ranging sensor. The controller circuit is configured to determine a search area extending from the host vehicle. The controller circuit is further configured to determine a first histogram comprising counts of occurrences of the range rates detected within the search area. The controller circuit is further configured to determine a second histogram comprising the counts of occurrences of a portion of the range rates detected within the search area. The controller circuit is further configured to determine that a trailer is being towed by the host vehicle based on the first histogram and the second histogram.
