Vehicle Sensor Reference Matching for Autonomous Route Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous and partially autonomous vehicle control systems require elaborate setup and additional sensors for precise navigation, which is inefficient and costly.
Innovation Solution
A control method that uses stored sensor data from manual vehicle operation to enable autonomous driving by comparing recorded sensor data with the stored data, allowing the vehicle to replicate the learned journey without additional sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional sensors are installed for precise navigation in autonomous vehicle control, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes existing vehicle sensors serve dual purposes: their original functions plus navigation reference functions. The sensor data serves both operational control and trajectory reference, eliminating the need for dedicated navigation sensors
Solution Approach 2:
The vehicle uses its own existing sensor system to generate and store reference trajectory data during manual operation, then uses this self-generated data for autonomous navigation, making the system self-sufficient without external infrastructure or additional sensors
2Measurement precision
If elaborate setup work is performed to establish reference trajectories, then navigation accuracy is improved, but loss of time and productivity decrease
Solution Approach 1:
The system performs preliminary trajectory learning during normal manual vehicle operation, storing sensor data for later autonomous use. This preliminary data collection happens naturally during regular work, avoiding separate setup phases
Solution Approach 2:
The system continuously collects and stores sensor data during manual operation that can be used for autonomous navigation. The same sensor data serves both real-time control and future autonomous reference, maintaining continuous useful action without interruption
