Detection system

A detection system, comprising:

• a ranging-sensor, the ranging-sensor configured to detect objects proximate to a host-vehicle;
• and
• a controller-circuit in communication with the ranging-sensor, the controller-circuit configured to 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, said first-group characterized by a first-distance indicated by the ranging-sensor, and determine a trailer-type being towed by the host-vehicle based on the trailer-distance.

A detection method, comprising:

• detecting, with a ranging-sensor, objects proximate to a host-vehicle;
• and
• determining, with a controller-circuit in communication with the ranging-sensor, 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, said first-group characterized by a first-distance indicated by the ranging-sensor, determining an axle-distance between the front of the trailer and a trailer-axle based on a second-group of objects, said second-group characterized by a second-distance indicated by the ranging-sensor, and determining a trailer-length based on the trailer-distance and the axle-distance.
