A detection system includes a radar-unit and a controller-circuit. The radar-unit is configured to detect objects proximate a host-vehicle. The controller-circuit is in communication with the radar-unit and is configured to determine a detection-distribution based on the radar-unit. The detection-distribution is characterized by a longitudinal-distribution of zero-range-rate detections associated with a trailer towed by the host-vehicle. The controller-circuit is further configured to determine a trailer-classification based on a comparison of the detection-distribution and longitudinal-distribution-models stored in the controller-circuit. The trailer-classification is indicative of a dimension of the trailer. The controller-circuit determines a trailer-length of the trailer based on the detection-distribution and the trailer-classification.

Detection system and method

Disclosed are systems that include a controller circuit in communication with a ranging sensor configured to detect objects proximate to a host vehicle. In an aspect, the controller circuit is configured to perform a first detection count of the detected objects, determine a first group of objects of the detected objects, determine a first distance to the first group of objects, utilize the first distance to determine a trailer distance between the host vehicle and a front of a trailer, determine a second group of objects of the detected objects, determine a second distance to the second group of objects, utilize the second distance to determine an axle distance between the front of the trailer and a trailer axle, and determine a trailer length based on the trailer distance and the axle distance. Methods are also disclosed.

Detection system

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.

Trailer detection system and method

A detection system includes a ranging-sensor and a controller-circuit. The ranging-sensor is configured to detect objects proximate to a host-vehicle. The controller-circuit is in communication with the ranging-sensor. The controller-circuit is configured to determine that a trailer is being towed by the host-vehicle and determine a trailer-distance between the host-vehicle and a front of the trailer based on a distance to a first-group of objects detected by the ranging-sensor. The first-group is characterized by a first-distance indicated by the ranging-sensor. The controller-circuit determines an axle-distance between the front of the trailer and a trailer-axle based on a second-group of objects. The second-group is characterized by a second-distance indicated by the ranging-sensor. The controller-circuit determines a trailer-length based on the trailer-distance and the axle-distance.
