Abstract
A movable running board system which includes a running board which is supported by a movable under carriage. The movable under carriage is coupled to a motor wherein the motor is capable of moving the running board between a fully extended position and a retracted position. The motor is coupled to a motor controller which receives a signal from a door position switch. When the door position switch indicates that the vehicle door is opened, the motor controller commands the motor to manipulate the running board to a fully extended position. Once the vehicle door is closed the door position sensor sends the "closed door" signal to the motor controller which, then in turn, commands the motor to retract the running board into the retracted position.
