Embodiment Construction

[0024] [24] Referring to the drawings, wherein like reference numerals refer to like parts throughout the several views. An obstacle detection device according to a first embodiment of the present invention is illustrated generally at 10 . Figure 1a is a partially exploded view of a motor vehicle 12 having a body 14 with a door assembly 16 rotatably mounted thereto.

[0025] [25] The door assembly 16 is illustrated as a side door, specifically a rear passenger door, however, any vehicle door is contemplated within the spirit and scope of the present invention, including swing or deck lids, hoods, sliding side doors, lift gates, transoms, wing gates or similar.

[0026] [26] The door assembly 16 includes a door frame 18, for example via a door hinge 20 ( Figure 1b shown) is pivotally connected to the body 14 about a pivot A. Door assembly 16 also includes a door locking mechanism 22 to secure the door in a closed position thereby eliminating opening 24, which is defined as ...

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.

Description

technical field [0001] [1] The present invention relates to an obstacle detection device for a vehicle door. Background technique [0002] [2] Vehicle doors or door assemblies have been incorporated into vehicle designs since the early days of automobiles (also known as motor vehicles) to protect the contents of the vehicle and to allow vehicle entry and exit. The door assembly is typically hinged to the vehicle body so that the door can pivot toward an open position and toward a closed position, and the door assembly typically includes a locking mechanism to secure the door in the closed position. The size, weight, geometry and opening track of the door assembly will vary from vehicle to vehicle. [0003] [3] A standard motor vehicle door assembly includes a frame having an inner front frame member to form the front edge of the door assembly; an inner rear frame member to form the rear edge of the door assembly; a waist reinforcement member to connect the front frame membe...
