First Claim
1. A method of controlling a door of a motorized vehicle to move to an open position, the vehicle including a body frame supported by a chassis, a powertrain mounted to the chassis, and a door assembly including a first member defining a first axis, a first support member pivotally coupled to the door and defining a second axis, a linkage assembly including a first arm and a second arm, the first arm and the second arm being pivotally coupled to one another, a cross member having a first end and a second end, the first end having a first pin for slidably engaging the first slot and the second end being coupled to the first member, a drive mechanism, and a cinching assembly including an actuator, the method comprising:
- providing a controller having a plurality of inputs and a plurality of outputs, a signal receiver, a door actuator, a solenoid, and a plurality of sensors including an actuator position sensor, a PRNDL sensor and a pivot arm sensor;
storing an open door process in a memory of the controller, the open door process being executable by a processor of the controller;
receiving a first signal from the signal receiver, the first signal being an instruction to execute the open door process;
receiving a second signal from the PRNDL sensor, the second signal being indicative of a powertrain position;
detecting a position of the actuator with the actuator position sensor and communicating the actuator position to the controller;
sending a command to the door actuator to unlatch the door;
operably controlling the drive mechanism to pivot the first member about the first axis only if the PRNDL sensor detects the powertrain position being a park position; and
controllably moving the door to the open position.

Abstract
A door assembly for a motorized vehicle includes a door configured to move between an open position and a closed position, a first member defining a first axis, and a first support member pivotally coupled to the door and defining a second axis. A linkage assembly includes a first arm and a second arm. The first arm and the second arm are pivotally coupled to one another, where the first arm is coupled to the first member at a location offset from the first axis and the second arm defines a first slot. A cross member has a first end and a second end. The first end has a first pin for slidably engaging the first slot and the second end being coupled to the first member. The door is movable between the open and closed positions as the first member pivots about the first axis.
