A recently granted patent (Publication Number: US11847833B2) discloses a powered door system designed to enhance safety by incorporating a noncontact sensor with an obstacle detection zone. The system includes an electronic control unit that receives data from the sensor to identify objects within the sensor's field-of-view. If an object is detected within the obstacle detection zone, the system automatically initiates actions such as issuing an alarm, stopping or reversing the door's movement to prevent contact with the object. The sensor's placement inside the vehicle, behind the window, ensures accurate detection and timely response to potential obstacles, improving overall safety.

Furthermore, the patent details various configurations of the powered door system, including applications for sliding doors, swinging doors, tailgates, and liftgates of vehicles. The system's ability to dynamically adjust the obstacle detection zone based on the door's movement, ignore sensor data during specific door operations, and even detect human gestures for door operation highlights its advanced functionality. With features like communication over a serial data bus and the use of millimeter wave radar sensors, the powered door system aims to provide a comprehensive solution for obstacle detection and automatic response, enhancing safety and convenience for vehicle users.
