Embodiment Construction

[0014] Referring now to the figures, and particularly FIG. 1, a control system for an auxiliary device is shown. The control system may include an after-market type controller 100 (i.e., not OEM equipment) that is provided with an auxiliary device such as a wheelchair lift or ramp for controlling the auxiliary device. One exemplary auxiliary device is illustrated in FIG. 2 as a vehicle wheelchair lift 10, but the auxiliary device may be a wheelchair ramp or other device that helps a mobility-challenged person enter and exit a vehicle, building or other structure. As shown in FIG. 2, by way of example, the wheelchair lift 10 is installed in vehicle V such as a bus, van, or other suitable vehicle. Wheelchair lift 10 is installed in a doorway D and is bolted or otherwise fixedly attached to the vehicle floor F. With reference to the axis shown in FIG. 2, a direction closest to or toward the vehicle V shall be referred to as inboard (IB), whereas the direction away from or farthest from...

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.

Description
