Abstract
An electronic latch system for a motor vehicle includes an electronic latch (e-latch) including an e-latch controller within a door of the vehicle. A plurality of radar sensors are located within the door for performing non-contact detection of objects around the vehicle. The radar sensors include an outside-face sensor adjacent an outside face of the door to sense an object within a first sensing zone extending from the outside face. The radar sensors also include an inner sensor adjacent an inside surface of the door to sense an object within a second sensing zone extending from the inside surface. The radar sensors also include a shut-face sensor adjacent a shut face of the door to sense an object within a third sensing zone extending from the shut face. The e-latch includes a light source for projecting a warning image and an audio source for generating an audible warning.
