An improved system for detecting the presence of an object in the path of a liftgate relies upon the sensor and transmitters those used for collision avoidance systems to detect the presence of an object when the tailgate is closed in auto-mode. The sensors are actuated when the liftgate is moved to its closed position. When an object is detected, further movement of the liftgate stops rearward accordingly. Now a day, the capacitive sensors are widely used for the anti-pinch system considering the production cost and adaptability. Pedestrians are in at risk of meeting with fatal accidents or tailgate get mal-function due to the presence of the hard object. Car manufacturers have initiated to support by offering collision avoidance systems that detect pedestrians and objects on the powered tailgate.
