Remote Vehicle Parking Control With Single-Button Key Operation
Find Innovative SolutionsGenerate Solutions
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 unlock the vehicle and permit movement control, eliminating the need for additional buttons and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If parking control functions are added to the terminal device, then the vehicle control functionality is improved, but the number of buttons on the terminal device increases
Solution Approach 1:
The existing terminal device is designed to perform multiple functions using a limited set of buttons. The control unit interprets different button press patterns (single press, long press, combination presses) to execute various vehicle control operations including door locking/unlocking and parking control, allowing one device to serve multiple purposes without adding physical buttons
Solution Approach 2:
The system changes the operational parameters of the existing buttons by introducing different press duration thresholds and press pattern recognition. By detecting whether a button is pressed for a short or long duration, or in combination with other buttons, the system expands the functionality of the terminal device without requiring additional physical buttons
2Reliability
If additional buttons are added to the terminal device for parking control, then the parking control signal transmission is improved, but the manufacturing cost increases
Solution Approach 1:
The terminal device uses existing buttons to transmit multiple types of control signals including parking control commands. The control unit distinguishes between different signal types by analyzing button press patterns, eliminating the need for dedicated buttons for parking control and thereby reducing manufacturing costs
3Ease of operation
If more buttons are provided on the terminal device, then the parking control operation is improved, but the user confusion increases
Solution Approach 1:
The system provides feedback to the user through the vehicle's display device, which shows the current operational state and confirms received commands. This feedback mechanism helps users understand which button press was registered and what action will be taken, reducing confusion despite using existing buttons for multiple functions
Data Source
AI summary
A vehicle control method and a vehicle control device are configured to control the movement of a vehicle based on operation of a terminal device located outside the vehicle. 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 movement control is permitted.
