Abstract
A vehicle door latch assembly includes a first proximity sensor on a first side of a door handle and a second proximity sensor on a second side of the door handle. The assembly also includes a latch operative to latch the door closed and to unlatch the door to allow the door to open. The assembly further includes control circuitry for activating the latch to unlatch the door based on an object such as an operator's hand sensed with both the first and second proximity sensors.
