Autonomous Driving Interface Box for Vehicle Anti-Theft Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicles can be stolen when a malicious person enters the driver's seat due to the vehicle being in a Ready-ON state, allowing manual operation.
Innovation Solution
A vehicle configuration that includes an autonomous driving kit and a vehicle control interface box to shift the vehicle mode state to a standby mode when activated, prohibiting driver operation and enabling secure autonomous driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle is activated in Ready-ON state allowing manual operation, then the ease of operation is improved, but the security against theft deteriorates
Solution Approach 1:
The vehicle control interface box dynamically changes the vehicle mode state based on the activation source. When activated by the autonomous driving kit, the system transitions to standby mode prohibiting manual operation, while maintaining the ability to switch to autonomous driving mode. This dynamic state management resolves the contradiction by adapting the operation mode to the activation context.
Solution Approach 2:
The system changes the operational parameter of the vehicle by introducing a standby mode with a specific flag state when activated by the autonomous driving kit. This parameter change (from ready-ON to standby) restricts manual operation while preserving autonomous functionality, thereby improving security without completely sacrificing operability.
2Reliability
If the vehicle mode is restricted to standby mode after activation, then the security against theft is improved, but the ease of operation deteriorates
Solution Approach 1:
The system provides dynamic mode switching capability, allowing transition from standby mode to autonomous driving mode when appropriate conditions are met. This ensures that while security is enhanced through standby mode restriction, legitimate autonomous operation remains accessible through proper authentication channels.
Solution Approach 2:
The autonomous driving kit acts as an intermediary between the vehicle activation and the mode selection. When the kit activates the vehicle, it mediates the transition to standby mode, and subsequently can request transition to autonomous driving mode, thereby controlling the operation flow to balance security and functionality.
3Ease of operation
If the vehicle allows manual mode operation, then the ease of operation is improved, but the vulnerability to unauthorized operation increases
Solution Approach 1:
The system performs preliminary authentication and mode setting before allowing operation. When activated by the autonomous driving kit, the vehicle is preemptively set to standby mode with manual operation prohibited, preventing unauthorized manual operation before it can occur. Legitimate manual operation can only occur when the vehicle is properly activated in ready-ON state.

AI summary
A vehicle includes: a vehicle platform configured to execute a plurality of predetermined functions of the vehicle; an autonomous driving kit that is configured to issue an instruction for autonomous driving and is attachable to and detachable from the vehicle platform; and a vehicle control interface box configured to communicate with the autonomous driving kit and issue a control instruction to the vehicle platform based on an instruction from the autonomous driving kit. A vehicle mode state indicating a state of the vehicle platform includes a manual mode under control of a driver of the vehicle, an autonomous driving mode under control of the autonomous driving kit, and a standby mode in which an operation on the vehicle platform by the driver is prohibited. The vehicle mode state is shifted to the standby mode when the vehicle platform is activated based on a control instruction from the autonomous driving kit.
