Abstract: A system and method for coordinating movement of a powered sliding door module and an access ramp for a vehicle is shown in FIG. 5 An OEM key fob (26a) is modified to send a non-OEM signal when a passenger side sliding door button is pressed A non-OE controller (70) receives the non-OEM signal and, depending on whether the passenger side sliding door is opened or closed, and whether the access ramp is stowed or deployed, sends the OEM signal to open the door before deploying the ramp, or delays sending the OE signal until the ramp is stowed In another embodiment, an OEM receiver is modified to receive a non-OEM signal and the control configured to receive the OEM signal and send or delay sending of the non-OEM signal depending on the condition of the door and ramp.

Abstract: A system and method for coordinating movement of a powered sliding door module and an access ramp for a vehicle. A system control board communicates with a current detector that can detect current on the power wires for the sliding door's motor. The current detector signals the system control board when it detects current and the system control board determines whether the ramp is stowed or deployed. If the ramp is deployed, the system control board stops and reverses the door so that the door remains open. The system control board then stows the ramp and closes the door. If the ramp is stowed, the system control board waits for the current in the door motor to return to zero and then determines if the door is completely open. If the door is not completely open the system control board does nothing. If the door is completely open, the system control board deploys the ramp.

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.

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.

Abstract: A wheelchair lift having a pivot and a platform. A rotary position sensor is mounted at the pivot and configured to generate an output signal. A controller is configured to receive the output signal of the rotary position sensor and determine the position of the platform based on the output of the rotary position sensor.

Abstract: A ramp deployment control system includes a controller, a kneeling motor operatively coupled to the controller and a ramp motor operatively coupled to the controller. The controller energizes the kneeling motor to kneel or stand a vehicle and energizes the ramp motor to deploy or stow a ramp. The controller is operatively coupled to a communication pathway, and a door control system is operatively coupled to the controller. The door control system is operable to monitor and control operation of a door. A standard control module is operatively coupled to the communication pathway and is operable to send door operation commands on the communication pathway. The controller selectively delays execution of the door operation commands by the door control system while operating the ramp motor to deploy or stow the ramp.
