Remote Vehicle Control via Position-Based Touch Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote control methods do not effectively prompt operators to carry the extension unit for remote operation, leading to potential misuse or ineffective remote control of vehicles.
Innovation Solution
A vehicle remote control method and device that set command touch operations based on the relative position between the vehicle and the extension unit, ensuring the operator carries the unit by matching the input touch operation with the predetermined command touch operation, thus enabling autonomous travel control only when the operator is correctly positioned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle allows remote operation without verifying extension unit carrying status, then the ease of operation is improved, but the reliability and safety deteriorate due to potential misuse
Solution Approach 1:
The system performs preliminary verification of the extension unit's carrying status before allowing remote operation to commence. The determination unit checks whether the operator is carrying the extension unit prior to enabling touch operations, ensuring that only authorized operators can control the vehicle remotely.
Solution Approach 2:
The system continuously monitors and detects the relative position between the vehicle and the extension unit during operation. This feedback mechanism allows the determination unit to verify in real-time whether the operator remains in the correct position, and to suspend operations if the extension unit is misplaced, thereby maintaining safety throughout the remote control process.
2Reliability
If the system requires strict verification of extension unit carrying status, then the reliability is improved, but the ease of operation deteriorates due to additional constraints
Solution Approach 1:
The extension unit itself serves as the verification mechanism. By detecting the relative position between the vehicle and the extension unit, the system uses the extension unit's own position information to determine whether the operator is carrying it, eliminating the need for separate verification devices or complex authentication processes.
3Reliability
If the command touch operation is set based on relative position, then the reliability is improved by preventing misuse, but the device complexity increases due to position detection and determination mechanisms
Solution Approach 1:
The extension unit serves multiple functions: it acts as both the keyless entry device and the position verification tool. The same extension unit used for vehicle access also provides the position information needed for remote operation authorization, eliminating the need for separate verification hardware and reducing overall system complexity.
Solution Approach 2:
The determination unit acts as an intermediary that processes the relative position information between the vehicle and extension unit, and translates this spatial relationship into operational authorization decisions. This mediator simplifies the control logic by centralizing the verification process in a dedicated component rather than distributing complexity across multiple systems.

AI summary
The relative position between a vehicle (V) and an extension unit (22) located outside the vehicle (V) is detected, and a command touch operation for operating the vehicle (V) with a remote operation device (21) is set in accordance with the detected relative position. The touch operation of an operator (U) is detected by a touch panel of the remote operation device (21), and a determination is made as to whether or not the detected touch operation is the command touch operation. When the touch operation is the command touch operation, the vehicle (V) is controlled to execute autonomous travel control. The vehicle (V) has an autonomous travel control function.
