Solution Overview

Problem

Existing vehicle door control systems often result in collisions with obstacles when automatically opening or closing, leading to potential damage and poor comfort due to the lack of adaptive control modes.

Innovation Solution

A method and device that determine the target control mode for a vehicle door based on the distance to an obstacle, employing fully automatic, semi-automatic, and assistive modes to safely open or close the door, preventing collisions and enhancing comfort by adapting control according to detected signals and distances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic door controlling is adopted, then the comfort of the vehicle is improved, but the door might collide with obstacles and be damaged

Engineering Contradiction:
Improvedoor controlling comfortVSAvoiddoor collision safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system dynamically adjusts the door control mode (fully automatic, semi-automatic, or assistive) based on the real-time distance between the door and obstacles. When the distance is large, fully automatic mode provides high comfort; when the distance is small, the system switches to semi-automatic or assistive mode to prevent collision, thus adapting the control strategy to changing conditions

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously detects the distance between the door and obstacles using sensors, and uses this feedback information to determine the appropriate control mode. The controller adjusts the door control strategy based on the detected distance, ensuring safe operation while maintaining comfort when conditions permit

Inventive Principle:
Principle #23Feedback

2Ease of operation

If fully automatic door control is used, then the comfort is improved, but the system complexity increases

Engineering Contradiction:
Improvedoor controlling automationVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The door control function is segmented into three distinct modes (fully automatic, semi-automatic, and assistive mode), each with different levels of automation. The system selects the appropriate mode based on distance conditions, breaking down the complex control problem into manageable segments with clear control logic for each

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed are a vehicle and a controlling method and device therefor. The controlling method includes: acquiring a first distance between a door of the vehicle and an obstacle in an environment where the door is located; determining a target controlling mode of the door according to a first target distance interval to which the first distance belongs, wherein controlling modes of the door include a fully automatic mode, a semi-automatic mode and an assistive mode; and controlling the door according to the target controlling mode. By using the method, in the controlling of the door, different controlling modes are adopted according to the distance between the door and an obstacle, and the door is controlled according to the corresponding controlling mode, whereby the door can be opened or closed safely, and the door can be controlled to be opened or closed in different manners, which improves the comfort.
