Autonomous Driving Controller Temporary Route Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems fail to generate a driving route when obstacles are present, leading to suspended autonomous driving operations until the obstacle is cleared, which can result in insufficient enablement of autonomous driving.
Innovation Solution
The system transitions to an autonomous driving disable mode and generates temporary driving route information by tracking neighboring vehicles' movements using sensors like cameras, lidar, and radar, and updates log information to adapt to changing circumstances, allowing the vehicle to continue moving based on observed neighbor movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system generates driving route information based on rules and traffic regulations, then the driving route meets traffic regulations and avoids contact with surrounding objects, but the autonomous driving operation is suspended when obstacles are present and the driving route cannot be generated
Solution Approach 1:
The system dynamically switches between rule-based autonomous driving mode and temporary driving route generation mode based on the availability of valid driving routes. When obstacles prevent rule-based route generation, the system transitions to tracking neighboring vehicles and generating temporary routes, enabling continuous operation while maintaining safety through mode switching.
Solution Approach 2:
The system introduces neighboring vehicle tracking data as an intermediary source of driving route information. When rule-based route generation fails due to obstacles, the system uses sensed movement data from neighboring vehicles to generate temporary driving routes, serving as a mediator between the failure of primary route generation and the need for continuous driving operation.
2Reliability
If the system suspends autonomous driving until obstacles are eliminated, then the driving route meets traffic regulations, but the autonomous driving functionality is insufficiently enabled in actual driving circumstances
Solution Approach 1:
The system dynamically adapts its operating mode based on environmental conditions. When obstacles make rule-based route generation impossible, the system transitions to a temporary route generation mode that tracks neighboring vehicles, allowing the system to adapt to actual driving circumstances while maintaining safety through continuous monitoring and validation.
Solution Approach 2:
The system changes the parameters of route generation by switching from strict rule-based parameters to temporary route parameters based on neighboring vehicle movements. This parameter change allows the system to operate in circumstances where traditional rule-based parameters would fail, improving adaptability while maintaining safety through the threshold time mechanism.
3Productivity
If the system generates temporary driving route information based on neighboring vehicle movements, then continuous operation is enabled, but additional sensors and processing are required
Solution Approach 1:
The system uses the existing sensor suite already deployed for primary autonomous driving functions to also track neighboring vehicles and generate temporary driving routes. By making the sensor system multi-functional, the system enables continuous operation through temporary route generation without requiring additional specialized sensors, thus avoiding increased device complexity.
Solution Approach 2:
The system uses its own existing sensor capabilities and processing resources to generate temporary driving routes when needed, rather than requiring external assistance or additional dedicated systems. The autonomous driving controller leverages its inherent sensing and computation abilities to provide the temporary route generation function, avoiding additional complexity.
