Abstract

A vehicle proximity switch and method are provided having learned sensitivity control. The switch includes a proximity sensor, such as a capacitive sensor, installed in a vehicle and providing a sense activation field. Also included is sense control circuitry processing the activation field to sense user activation of the switch by comparing the activation field to a threshold. The switch further includes sensitivity control circuitry learning a user sensitivity based on user activation of a sensor and controlling the sensitivity of one or more proximity switches.
