Fault tolerant power liftgate obstruction detection system
A system and method detects an obstruction in the path of a vehicle access control member moving from an open position to a closed position. The method includes transmitting a detection signal along an edge of the member towards a reflective surface mounted on the member. The detection signal includes a sequence of pulses having different amplitudes with the amplitudes varying linearly moving from a first pulse to a final pulse of the sequence of pulses. The method further includes receiving a detection response signal corresponding to the detection signal following reflection of the detection signal by one of the reflective surface and the obstruction. The detection response signal includes another sequence of pulses and the method further includes generating an obstruction signal indicating whether the obstruction is in the path of the access control member responsive to differences in amplitude between adjacent pulses in the sequence of pulses.
