Vehicle Activation Code Verification for Safe Remote Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote vehicle operations, there is a risk of accidents during start-up due to operators mistakenly controlling the wrong vehicle, as they cannot visually confirm the vehicle they are operating, leading to potential damage to the vehicle, property, or people.
Innovation Solution
An on-board control unit and off-board control station system that uses wireless communication to verify the activation code, embedding the code in camera images transmitted to the operator, ensuring that the video feedback corresponds to the intended vehicle, thus preventing incorrect control inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator remotely operates the vehicle without visual confirmation, then the operator can operate the vehicle from a distance, but the operator cannot verify the vehicle identity, leading to potential control of the wrong vehicle
Solution Approach 1:
The system displays camera images captured by the vehicle to the operator, providing visual feedback that confirms the vehicle identity before remote operation begins. This feedback mechanism allows the operator to verify they are controlling the correct vehicle, resolving the contradiction between remote operation capability and identification accuracy.
Solution Approach 2:
The system requires the operator to visually confirm the vehicle through camera images before initiating remote operation. This preliminary verification action ensures correct vehicle identification is established before the actual remote control begins, preventing control of the wrong vehicle while maintaining remote operation capability.
2Ease of operation
If the operator aggressively moves controls to obtain a reaction, then the operator can test the vehicle response, but this may cause damage to the vehicle or harm to people if the wrong vehicle is controlled
Solution Approach 1:
The camera image feedback displayed to the operator provides visual confirmation of the vehicle's actual state and surroundings before the operator tests vehicle response. This allows the operator to safely test controls knowing they are controlling the correct vehicle, eliminating the need for aggressive control movements and preventing potential damage or harm.
Solution Approach 2:
The system requires preliminary visual verification of the vehicle through camera images before the operator begins testing vehicle responses. This preliminary action ensures the operator is controlling the correct vehicle, allowing safe and gentle control testing without risk of damage or harm to people.
3Adaptability or versatility
If multiple remote controlled machines operate within the same system, then the system can control multiple vehicles, but it becomes critical to ensure the operator is controlling the intended vehicle
Solution Approach 1:
The system displays unique camera images from each vehicle to the operator, providing visual feedback that allows the operator to distinguish and verify the identity of each vehicle in the multi-vehicle system. This feedback mechanism ensures the operator controls the intended vehicle while maintaining the ability to operate multiple vehicles.
Solution Approach 2:
Before operating any vehicle in the multi-vehicle system, the operator must perform preliminary visual verification by viewing the vehicle's camera images. This preliminary action ensures correct vehicle identification and selection, maintaining control accuracy while enabling versatile multi-vehicle operation.
