DOOR AND RAMP INTERFACE SYSTEM
First Claim
1. An access system for a vehicle having a door control system that opens and closes a vehicle door, the door control system coupled to a vehicle data bus, the access system comprising:
- a ramp control system including a ramp that is movable between a stowed position and a deployed position;
an interface system coupled to and communicating with the ramp control system to initiate movement of the ramp between the stowed and deployed positions, and to receive ramp status signals indicating whether the ramp is stowed or deployed;
a gateway module coupled to the vehicle data bus for communication thereon; and
a gateway bus coupled to the gateway module and the interface system for carrying data signals therebetween, wherein the interface system relays the ramp status signals to the gateway module via the gateway bus, and wherein the gateway module relays the ramp status signals to the door control system via the vehicle data bus.

Abstract
An access system for a vehicle includes a gateway module that connects to the vehicle data bus, and an interface system coupled to the gateway module via a gateway bus. The interface system is also coupled to a ramp control subsystem that operates to stow and deploy a ramp for providing wheelchair access to the vehicle. A door control subsystem is coupled to the vehicle data bus and operates in response to data signals sent over the vehicle data bus. The gateway module is configured to relay signals relating to the status of the ramp from the gateway bus to the vehicle data bus to coordinate operation of the door and the ramp.

21. A method for coordinating the operation of a vehicle power door with a ramp of an access system that provides wheelchair access to the vehicle when the door is open and the ramp is deployed, the vehicle including a vehicle data bus that carries data signals to control operation of the door, the method comprising:
-
coupling a gateway module to the vehicle data bus for communication on the vehicle data bus; coupling an interface system to the gateway module via a gateway bus; coupling the interface system to a ramp control subsystem that operates to stow and deploy the ramp and that sends a signal to the interface system indicating when the ramp is stowed; locating an activation indicator in the vehicle that operates in response to a request to open or close the door; coupling the interface system to an activation indicator to detect operation of the activation indicator; and moving the ramp in response to detecting operation of the activation indicator. - View Dependent Claims (22, 23, 24)
