APPARATUS AND METHOD FOR DETERMINING THE CLOSING VELOCITY OF A VEHICLE DOOR
An apparatus for measuring a closing velocity of a door of a vehicle having a body is provided. The apparatus includes a base, a door-closing member, an actuator, and a sensor assembly. The door-closing member is movably coupled to the base. The actuator is coupled to the base and the door-closing member and is configured to move the door-closing member.

9 . The apparatus of claim 7 , wherein the sensor assembly includes at least one ultrasonic sensor and the second sensor assembly includes at least one infrared sensor.
10 . The apparatus of claim 7 , wherein the second sensor assembly further comprises a vehicle position sensor coupled to the base and in operable communication with the controller, the vehicle position sensor being configured to detect when the door of the vehicle is within a predetermined distance of the door-closing member and generate a signal representative thereof, and wherein the controller is configured to actuate the actuator system when the vehicle is in the first location and the door is within the predetermined distance of the door-closing member.
11 . An apparatus for measuring a closing velocity of a door of a vehicle having a body, the apparatus comprising:
a base;
a door-closing member movably coupled to the base;
an actuator coupled to the base and the door-closing member and configured to move the door-closing member;
a vehicle position sensor assembly coupled to the base and configured to detect a position of the vehicle relative to the base and generate a signal representative thereof,
a door position sensor assembly coupled to the base and configured to detect a position of the door of the vehicle relative to a selected portion of the vehicle and generate a signal representative thereof,
a controller in operable communication with the actuator, the vehicle sensor assembly, and the door position sensor assembly, the controller being configured to:
cause the actuator to move the door-closing member in response to the vehicle being in a first position relative to the base, the movement of the door-closing member causing the door of the vehicle to move at a predetermined velocity; and
generate an alert signal representative of the position of the door of the vehicle relative to the selected portion of the vehicle in response to the vehicle being in a second position relative to the base.
12 . The apparatus of claim 11 , wherein the detected position of the door of the vehicle relative to the selected portion of the vehicle is indicative of at least one of the door of the vehicle being completely closed the door of the vehicle being at least partially opened.
13 . The apparatus of claim 11 , wherein the door position sensor assembly is configured to measure a first distance between the door position sensor assembly and the selected portion of the vehicle and a second distance between the door position sensor assembly and the door of the vehicle, and wherein a difference between the first and second distances being greater than a predetermined threshold is indicative of the door of the vehicle being at least partially opened.
14 . The apparatus of claim 11 , wherein the vehicle position sensor assembly comprises a first sensor configured to detect a position of a wheel of the vehicle relative to the base and a second position configured to detect a position of the door relative to the base.
15 . The apparatus of claim 11 , wherein the vehicle position sensor assembly comprises at least one infrared sensor and the door position sensor assembly comprises at least one ultrasonic detector.
16 . A method for measuring a closing velocity of a door of a vehicle having a body, the method comprising:
moving the vehicle between first and second positions;
automatically actuating a door-closing member during the movement of the vehicle when the vehicle is in the first position, the actuation of the door-closing member causing the door of the vehicle to move relative to the body of the vehicle at a predetermined velocity;
automatically detecting a position of the door of the vehicle relative to a selected portion of the vehicle during the movement of the vehicle when the vehicle is in the second position; and
generating a signal representative of the position of the door of vehicle relative to the selected portion of the vehicle after the vehicle is moved into the second position.
