Vehicle access control system

A method for an access system in a vehicle, the vehicle including a power door movable between an open position and a closed position, and a door motor operable to move the power door between the open and closed positions in response to electrical power carried by a door power wire, the method comprising:

• installing a ramp in the vehicle, the ramp movable between a stowed position and a deployed position and providing access to the vehicle when the ramp is in the deployed position and the door is in the open position;
• coupling a ramp control system to the ramp, the ramp control system operable to move the ramp between the stowed position and the deployed position;
• operably associating a current detector with the door power wire, the current detector operable to detect initiation of electrical current flowing through the door power wire;
• installing an access system controller in the vehicle;
• coupling the access system controller with the ramp control system for communication therewith;
• and
• coupling the access system controller to the current detector for communication therewith.

An access system for a vehicle, the access system comprising:

• a power door movable between an open position and a closed position;
• a door motor for moving the door between the open and closed positions;
• a door power wire for supplying electrical power to the door motor;
• a current sensor for detecting initiation of current flowing through the door power wire;
• a ramp movable between a stowed position and a deployed position;
• and
• a controller for coordinating operation of the ramp and the door in response to signals received from the current sensor.
