ELECTRONIC CONTROL SYSTEM AND METHOD FOR AN AUXILIARY DEVICE INTERLOCK SAFETY SYSTEM
First Claim
1. A control system for an auxiliary vehicular access device, the control system comprising:
- a communication bus for carrying communication signals between a plurality of vehicle components;
a vehicle controller coupled to the communication bus;
a power sliding door subsystem operable to open and close a vehicle door in response to at least one of the communication signals;
an access device moveable between stowed and deployed positions;
an access controller coupled to the access device for controlling movement of the access device between the stowed and deployed positions, and coupled to the communication bus, wherein the access controller delays operation of at least one of the power sliding door subsystem and the access device until the other of the power sliding door subsystem and the access device is in an appropriate state.

Abstract
A controller, control system and method for controlling an auxiliary device comprising a wheelchair lift, ramp, or the like are provided. An exemplary embodiment of the auxiliary device controller is microprocessor-based and communicates with a vehicle'"'"'s OEM controller for receiving a plurality of sensor inputs, which originate from OEM and auxiliary sensors, process the sensor inputs, and control various OEM and auxiliary systems relative to the sensor inputs to effect a number of safety interlocks. The controller may operate to coordinate various OEM and auxiliary subsystems to automate auxiliary device operation to reduce operator error.
