Vehicle Door Control Modes for Assisted Opening and Anti-Slam Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle doors require manual operation, which can be cumbersome, especially when both hands are occupied, and lacks intelligence in handling obstacles or user assistance.
Innovation Solution
A vehicle door system with a controller and actuating mechanism that operates in multiple modes, including electric, suspended, and manual modes, using sensors to control door movement, provide assistance, and prevent slamming, allowing for automatic operation, obstacle detection, and user-friendly interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used for vehicle door, then device complexity is reduced, but ease of operation deteriorates when hands are occupied
Solution Approach 1:
The patent replaces the purely mechanical door operation system with an electromechanical system. The actuating mechanism includes a motor driver that can be controlled electronically through the controller, substituting manual mechanical operation with an automated electromechanical system that responds to control signals.
Solution Approach 2:
The door system performs self-service by automatically detecting obstacles and adjusting its operation accordingly. The controller monitors the door's movement and automatically activates the actuating mechanism to prevent slamming or damage, without requiring user intervention or complex additional controls.
2Ease of operation
If automatic electric mode is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The actuating mechanism serves multiple functions: it can drive the door to open, drive the door to close, and hold the door suspended, all controlled by the same motor driver and controller. This multi-functionality reduces the need for separate mechanical systems for each operation mode.
Solution Approach 2:
The system dynamically switches between different operation modes (electric mode, suspended mode, manual mode) based on real-time conditions. The controller adjusts the actuating mechanism's behavior dynamically, allowing the door to be driven, held suspended, or operated manually depending on the situation.
3Reliability
If obstacle detection and protection modes are added, then reliability is improved, but device complexity increases
Solution Approach 1:
The system implements feedback control by monitoring the door's movement and external forces acting on it. The controller receives information about obstacles and external forces, and automatically adjusts the actuating mechanism's operation to prevent damage or slamming, improving reliability without requiring complex additional hardware.

AI summary
A vehicle has a vehicle door system, and the vehicle door system includes a vehicle door, an actuating mechanism, and a controller. The actuating mechanism is connected to the vehicle door and is configured to control a state of the vehicle door. The controller is configured to control, according to a current working mode of the vehicle door system, the actuating mechanism to control the state of the vehicle door. In the electric mode, the controller is configured to control the actuating mechanism to drive the vehicle door to open or close; a suspended mode. In the suspended mode, the controller is configured to control the actuating mechanism to keep the vehicle door suspended; and a manual mode. In the manual mode, the controller is configured to control, according to an external force acting on the vehicle door, the actuating mechanism to drive the vehicle door to move.
