Title: IMPROVED DOOR CONTROL SYSTEM
Abstract:
In an aspect, a door control system is provided for a vehicle door and includes a pushrod and a locking device. The pushrod has a first end connected to one of the vehicle body and the vehicle door. At least a portion of the locking device is mounted to the other of the vehicle body and the vehicle door. The locking device includes a leadscrew, a leadscrew nut, a housing, and a brake. The pushrod has a second end connected to the leadscrew nut. The leadscrew nut is constrained against rotation but is slideable along a guide path by movement of the pushrod, which causes rotation of the leadscrew. The brake is positionable in a braking position in which the brake prevents rotation of the leadscrew, and a release position in which the brake permits rotation of the leadscrew.
