Solution Overview

Problem

The addition of parking control functions to a terminal device increases the number of buttons, leading to higher manufacturing costs and potential user confusion.

Innovation Solution

A vehicle control method and device that utilize a single button on a terminal device to initiate vehicle movement control, allowing for the integration of parking control functions without increasing the number of buttons.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple buttons are added to the terminal device for parking control functions, then the functionality for vehicle control is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improveparking control functionVSAvoidnumber of buttons
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single button on the terminal device is designed to perform multiple functions: it can initiate parking control, lock/unlock vehicle doors, and permit movement control. By making this single button universal, the patent avoids adding multiple buttons while still providing comprehensive vehicle control functionality, directly resolving the contradiction between adaptability and device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple control functions (parking control, door locking, movement permission) into a single button operation. Instead of having separate buttons for each function, the system merges these functions into one unified control mechanism, reducing the number of physical buttons while maintaining full functionality

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple buttons are added to the terminal device for parking control functions, then the functionality for vehicle control is improved, but the ease of operation deteriorates due to potential user confusion

Engineering Contradiction:
Improveparking control functionVSAvoiduser confusion
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The single button serves as a universal control for multiple vehicle functions. Instead of presenting users with multiple separate buttons that could cause confusion about which button to press for which function, the system uses one clear, unambiguous button that performs all necessary control operations, thereby improving ease of operation while maintaining full functionality

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A vehicle control method and a vehicle control device are configured to control the movement of a vehicle based on the operation of a terminal device located outside the vehicle, wherein the vehicle receives from the terminal device a first signal indicating that a first button of the terminal device has been pressed, the vehicle doors are unlocked based on the reception of the first signal, and the vehicle is placed in a state in which the movement control is permitted.
