Autonomous Driving Device Driver Detection Travel Plan Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles traveling without a driver are at risk of theft, as existing technologies do not effectively prevent unauthorized access or track the vehicle's location.
Innovation Solution
An autonomous driving device that detects the presence or absence of a driver and generates travel plans with restrictions, such as lane change prohibition and speed reduction, to limit the vehicle's movement when no driver is present, and includes features like door locking and unmanned stop control to prevent unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle travels autonomously without driver presence detection and without travel restrictions, then the vehicle can operate efficiently and freely, but the risk of vehicle theft increases and the vehicle becomes harder to locate
Solution Approach 1:
The system performs preliminary detection of driver presence before autonomous travel begins. Based on this detection, it pre-establishes appropriate travel plans with or without restrictions. This preliminary action prevents theft risk before it can materialize during unrestricted autonomous operation.
Solution Approach 2:
The system dynamically adjusts travel plan restrictions based on real-time driver presence detection. When no driver is detected, restrictive travel plans are automatically applied; when a driver is present, normal travel plans are used. This dynamic adaptation resolves the contradiction between operational freedom and theft prevention.
2Loss of time
If the vehicle travels autonomously without driver presence detection and without travel restrictions, then the vehicle can reach destinations quickly, but it becomes difficult to locate the vehicle if theft occurs
Solution Approach 1:
The system pre-establishes different travel plans based on driver presence detection before autonomous travel begins. Restrictive travel plans that limit vehicle movement and make it easier to locate are prepared in advance for scenarios where no driver is present, preventing the need for rapid response if theft occurs.
Solution Approach 2:
The system changes key travel parameters such as speed limits, route restrictions, and lane change permissions based on driver presence detection. When no driver is detected, parameters are adjusted to reduce speed and restrict maneuvers, making the vehicle easier to locate and control in case of theft.
3Object-affected harmful factors
If the system adds travel restrictions when no driver is present, then the vehicle becomes easier to locate and theft risk is reduced, but the vehicle's operational flexibility and speed are limited
Solution Approach 1:
The system dynamically switches between restrictive and normal travel plans based on driver presence detection. This dynamic adaptation allows the vehicle to maintain high operational flexibility when drivers are present while automatically applying restrictions only when necessary for theft prevention, thus resolving the contradiction between security and flexibility.
Solution Approach 2:
The system applies different quality levels of travel plan restrictions to different operational contexts. Normal travel plans with full flexibility are used when drivers are present, while restrictive travel plans are applied only when no driver is detected. This localized application of restrictions maintains overall operational versatility while providing targeted theft prevention.

AI summary
An autonomous driving device for a vehicle includes: an actuator; and an electronic control unit configured to detect presence or absence of a driver, generate a first travel plan for causing the vehicle to travel autonomously, and generate a second travel plan by adding, to the first travel plan, a restriction including at least one of a lane change restriction and a vehicle speed restriction. The electronic control unit is configured to perform manned autonomous driving control for causing the vehicle to travel autonomously, by using the actuator, with the driver in the vehicle according to the first travel plan when the presence of the driver is detected, and perform unmanned autonomous driving control for causing the vehicle to travel autonomously, by using the actuator, with the driver not in the vehicle according to the second travel plan when the absence of the driver is detected.
