Abstract

An interface system is presented, which prevents operational interference between a vehicle power door and a ramp of an access system by interrupting power to the motors and actuators responsible for operating the door. The interface system includes a relay system that does not interrupt, read, signal, or otherwise interfere with the communication lines between a body control unit, door control unit, or remote control transmitter or receiver. Thus, the interface system functions without the need to receive and transmit signals on the vehicle'"'"'s communication bus. The interface system enables the ramp controller of the access system to be a separate module, which controls the ramp and kneel functions, because the only input the ramp controller provides to the power door system is to a ground signal that mimics that of a switch included in the vehicle.

Claims

1. An interface system for preventing operational interference between a vehicle door and a ramp installed in the vehicle, the interface system comprising:

a relay configured to provide power to a latch release; and

a relay configured to provide power to a motor configured to move the door;

wherein the relays are configured to provide power when the ramp is stowed.
