Capacitive sensors

The capacitive switch for liftgates and trunk lids makes loading and unloading vehicles with electrically operated liftgates and trunk lids more convenient. A simple foot movement is all that is needed to open and close the trunk.

A capacitive sensor below the bumper responds to a simple foot movement and passes this information to the keyless entry control unit in the vehicle. This checks the key holder's authority, and transmits the signal to the trunk lid control unit to automatically open or close the lid. Nuisance factors such as moisture on the bumper or passers-by who approach the vehicle do not affect the operation.
