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.
