Abstract
An obstruction detection device for a motor vehicle having a door assembly movably connected to a vehicle body is provided. The device controls the vehicle door's opening angle to prevent inadvertent contact with an object foreign to the vehicle, while providing the largest opening for vehicle ingress and egress. The obstruction detection device includes a controller that is operatively connected to at least one sensor configured to actively monitor and transmit signals to the controller indicative of the presence and corresponding proximity of the object relative to the door assembly. An actuator is operatively connected to and controlled by the controller. The actuator is configured to apply a selectively variable force that restricts the movement of the vehicle door assembly with respect to the vehicle body when the door is a predetermined distance from the object.
