ABSTRACT:
Methods and apparatus are provided for reducing the occurrence of vehicle door bumps against an adjacent object facing the door. The apparatus comprises one or more distance sensors mounted on the vehicle for measuring distance D from the door to the object, a brake for inhibiting outward movement of the door toward the object, a warning system and a controller coupled to the distance sensors, warning system and brake for applying the brake to inhibit further outward movement of the door when D≦D(MIN), a predetermined minimum distance away from the object. In a preferred embodiment, a first driver warning is activated when the initial door-to-object spacing D(INIT)≦D(SAFE), the maximum outward door reach. A second warning is desirably added when the door begins moving toward the object or has reached about (D(INIT))/2 and a third warning is activated when the brake is engaged.
