Abstract

The present disclosure relates generally to a perception sensor, including but not limited to an absolute position sensor, for detecting the angle of a wheelchair access device in a wheelchair accessible vehicle. The subject technology improves the safety of wheelchair access devices, such as wheelchair lifts and ramps, in traditional wheelchair accessible vehicles during ingress and egress of a passenger by alerting a vehicle operator or caretaker of unsafe angles and conditions. The subject technology may also be useful in autonomous vehicles (AV) for enabling automatic operation of a wheelchair access device, such as a ramp or lift, and facilitate the safe loading and unloading of a passenger seated in a wheelchair.
