Abstract
An access system for a vehicle includes an interface system that communicates with the vehicle data bus. The interface system also communicates with 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 to open and close a vehicle door in response to data signals sent over the vehicle data bus. When the vehicle door is open and the ramp is deployed, the interface system is configured to send a ramp deployed data signal over the vehicle data bus, which prevents the door control subsystem from closing the door on the deployed ramp.
