Vehicle Remote Control via Position-Based Touch Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote control systems require the operator to carry an extension unit to maintain control over the vehicle during autonomous travel, which can be inconvenient, especially in tight spaces where getting on or off the vehicle is difficult.
Innovation Solution
A remote control method and device that allow autonomous vehicle travel by setting a command touch operation based on the relative position between the vehicle and the extension unit, enabling operators to control the vehicle from outside while carrying the extension unit, using a touch panel to input commands for autonomous travel control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator places the extension unit in the vehicle or on the roof to operate the remote operation device without carrying it, then the operator can operate the vehicle from a distance, but the system cannot determine whether the operator is within the remote operation distance
Solution Approach 1:
The system continuously monitors the relative position between the extension unit and vehicle, and provides feedback by adjusting the command touch operation requirements. When the extension unit is not carried (detected via position feedback), the system modifies the touch operation thresholds to prevent unauthorized remote operation, ensuring reliable distance determination while maintaining operator convenience.
Solution Approach 2:
The command touch operation parameters are made dynamic rather than fixed. The system adjusts the touch operation sensitivity and recognition criteria based on the real-time relative position between the extension unit and vehicle. This dynamic adaptation allows the system to accommodate different operator scenarios (carrying vs. placing extension unit) while maintaining security against unauthorized operation.
2Reliability
If the command touch operation is set based on relative position between vehicle and extension unit, then the system can prompt the operator to carry the extension unit, but the system complexity increases
Solution Approach 1:
The extension unit serves multiple functions: it acts as both a keyless entry credential and a position reference for authentication. By making the extension unit multi-functional, the system avoids adding separate authentication devices, thereby maintaining reliability while minimizing the increase in system complexity.
Solution Approach 2:
The system uses the existing wireless communication infrastructure between the extension unit and vehicle to automatically determine relative position and authenticate the operator. No additional sensors or complex authentication mechanisms are required - the system leverages the existing components to provide self-service authentication based on position data.
Data Source
AI summary
The relative position between a vehicle and an extension unit located outside the vehicle is detected, and a command touch operation for operating the vehicle with a remote operation device is set in accordance with the detected relative position. The touch operation of an operator is detected by a touch panel of the remote operation device, 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 is controlled to execute autonomous travel control. The vehicle has an autonomous travel control function.
