Automatic Driving System Route Segmentation for Control Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high volume of detail information required for automatic driving control increases the cost of the automatic driving control device, and reducing this information may restrict desirable automatic driving control.
Innovation Solution
An automatic driving system that divides the route into block regions and outputs only the detail information currently required for automatic control to the automatic driving control device, allowing for efficient storage and processing while maintaining appropriate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detail information of the entire route is output to the automatic driving control device, then appropriate automatic driving control can be performed, but the storage capacity and processing requirements of the automatic driving control device are increased, leading to higher cost
Solution Approach 1:
The route is divided into multiple block regions, and detail information is segmented by block region. The automatic driving control device receives and processes detail information for only the current block region, not the entire route. This segmentation reduces the storage capacity and processing requirements while maintaining the ability to perform appropriate automatic driving control for the current segment.
2Device complexity
If the amount of detail information output to the automatic driving control device is decreased, then the cost of the automatic driving control device can be suppressed, but desirable automatic driving control may be restricted
Solution Approach 1:
The system dynamically adjusts the amount of detail information provided to the automatic driving control device based on the vehicle's current position and the block region being traversed. Instead of providing a static large amount of information for the entire route or a small fixed amount, the system provides the appropriate amount of information for the current block region, optimizing both cost and control quality dynamically throughout the journey.

AI summary
An automatic driving system mounted on a vehicle includes a navigation device that searches for a route from a current position of the vehicle to a destination, a high precision map unit that generates detail information of the route based on the searched route and map information, and an automatic driving control device that performs automatic control of acceleration and deceleration and steering of the vehicle using at least the detail information. The high precision map unit divides the route into a plurality of block regions and, out of the detail information corresponding to the block regions, outputs the detail information currently required for the automatic control to the automatic driving control device in a unit of block region.
