Patent Images
1. A vehicle door control system for a vehicle having a vehicle body and a vehicle door, comprising:
- a check arm having an end that is mounted to one of the vehicle body and the vehicle door;
a check arm holder at least a portion of which is mounted to the other of the vehicle body and the vehicle door; and
a controller that is configured to receive input from at least one sensor relating to a force being applied to the vehicle door, wherein the controller includes a memory and a processor, wherein the processor is programmed to selectably cause the check arm holder to apply a selected check force to the check arm to hold the vehicle door stationary, and, in at least a selected set of conditions, the controller is programmed to at least partially release the check force when the processor determines that the force being applied to the vehicle door reaches a selected initiation force,wherein the check arm holder includes a first brake member and a second brake member, a motor and a drive train through which the motor is operatively connected to at least one of the first and second brake members,wherein at least one element from the drive train is non-backdrivable.

Abstract
In an aspect, a vehicle door control system for a vehicle having a vehicle body and a vehicle door is provided, and includes a check arm having an end that is mounted to one of the vehicle body and the vehicle door, a check arm holder at least a portion of which is mounted to the other of the vehicle body and the vehicle door, and a controller. The check arm holder is configured to apply at least three different amounts of braking force to the check arm. The controller is programmed to control the operation of the check arm holder based on input from at least one sensor.

the size of a resistive force applied to the check arm during movement of the vehicle door;
the size of the check force applied to the check arm when the vehicle door is stationary;
the profile of a relationship between a resistive force applied to the check arm during movement of the vehicle door and the position of the vehicle door;
a maximum permissible speed of the vehicle door;
a maximum permissible open position for the vehicle door; and
a position of at least one virtual detent for the vehicle door.
