Abstract
An automated retractable step system has at least one linkage subassembly for attachment to a vehicle frame. A step is attached to the linkage subassembly and is movable between a stowed position and a deployed position. An actuator is coupled with the linkage subassembly for moving the step between the stowed and deployed positions. A sensor subassembly includes a sensing electrode and a reference electrode disposed adjacent to the sensing electrode and a driven shield electrode extending generally parallel to and in a spaced relationship with the sensing electrode and the reference electrode. A controller is electrically connected to the sensing electrode and to the reference electrode and to the driven shield electrode. The controller is also electrically connected to the actuator for controlling the actuator to move the step between the stowed position and the deployed position in response to the signal from the sensor subassembly.
