Patent attributes
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 mounted on the leadscrew, a housing including a guide path, 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 the 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.
