Cost effective auto-actuation door check

A system for controlling movement of a vehicle door relative to a primary vehicle structure, the system comprising:

• at least one ultrasonic sensor configured to detect a distance from a vehicle to an object in the vicinity of a vehicle and to provide input to a vehicle automatic parallel parking system;
• a door brake configured to prevent a vehicle door from opening beyond a variable maximum distance;
• the system utilizes a plurality of detected distances to a detected object taken at different times before a vehicle stops and a plurality of vehicle positions or velocities at different times before a vehicle stops corresponding to the times at which the detected distances are taken to determine a location of the detected object relative to the vehicle;
• and wherein:
• the system selectively actuates the door brake to prevent the vehicle door from contacting the detected object as the door is opened.
