DOOR CONTROL SYSTEM
First Claim
1. A vehicle door control system for a vehicle having a vehicle body and a vehicle door, comprising:
- a pushrod having a first end that is connected to one of the vehicle body and the vehicle door; and
a locking device at least a portion of which is mounted to the other of the vehicle body and the vehicle door, wherein the locking device includes a locking device leadscrew, a locking device leadscrew nut mounted on the locking device leadscrew, a locking device housing including a locking device leadscrew nut guide path, and a locking device leadscrew brake,wherein the pushrod has a second end that is connected to the locking device leadscrew nut, wherein the locking device leadscrew nut is constrained against rotation but is slideable along the locking device leadscrew nut guide path by movement of the pushrod, which causes rotation of the locking device leadscrew, wherein the locking device leadscrew brake is positionable in a braking position in which the locking device leadscrew brake prevents rotation of the locking device leadscrew, and a release position in which the locking device leadscrew brake permits rotation of the locking device leadscrew.

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 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.

13. A vehicle door control system, comprising:
-
a check arm having a first end that is connected to one of the vehicle body and the vehicle door; and a check arm keeper, at least a portion of which is mounted to the other of the vehicle body and the vehicle door, wherein the check arm keeper includes at least one plunger having a plunger cam surface, a plunger drive cam having a plunger drive camming surface that is engaged with the plunger cam surface, wherein rotation of the plunger drive cam in a first rotational direction increases a brake force applied by the at least one plunger on the check arm, and rotation of the plunger drive cam in a second rotational direction decreases a brake force applied by the at least one plunger on the check arm. - View Dependent Claims (14)

15. A vehicle door control system for a vehicle having a vehicle body and a vehicle door, comprising:
-
a pushrod having a first end that is connected to one of the vehicle body and the vehicle door; a locking device at least a portion of which is mounted to the other of the vehicle body and the vehicle door, wherein the locking device includes a locking device traveler that is movable along a locking device traveler guide path, and a locking device brake, wherein the pushrod has a second end that is connected to the locking device traveler, wherein the locking device traveler is movable along the locking device traveler guide path by movement of the pushrod, wherein the locking device brake is positionable in a braking position in which the locking device brake prevents movement of the locking device traveler, and a release position in which the locking device brake permits movement of the locking device traveler; a motor that is operable to move the locking device brake between the braking and release positions; a controller that controls operation of the motor; and a door force sensor that includes a first target path, and a second target path, and a first target that is connected to a first portion of the locking device traveler and movable along the first target path and a second target that is connected to a second portion of the locking device leadscrew nut and movable along the second target path, wherein the first portion of the locking device traveler is constrained for movement along a traveler path, and the second portion of the locking device traveler is movable relative to the first portion of the locking device traveler and is operatively connected to the first portion of the locking device traveler via a traveler spring, wherein the second end of the pushrod is connected to the second portion of the locking device traveler, wherein the first target is connected for movement with the first portion of the locking device traveler and wherein the second target is connected for movement with the second portion of the locking device traveler, wherein, when the locking device brake is positioned in the braking position, movement of the vehicle door drives relative movement between the first portion of the locking device traveler and the second portion of the locking device traveler via the pushrod, so as to generate relative movement between the first target and the second target, and wherein the door force sensor is connected to the controller so as to send signals to the controller that are indicative of the positions of the first and second targets, and wherein the controller is programmed to control operation of the motor based at least in part on a difference in the positions of the first and second targets relative to one another.
