Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a world where automated driving is being implemented, existing systems often provide insufficient information related to congestion, traffic restrictions, and other vehicle surroundings, limiting the effectiveness of vehicle control systems.
Innovation Solution
A vehicle control system that includes a surroundings information acquisition section, an automated driving controller, a communication section, and a communication controller to share vehicle surroundings information and automated driving status with other devices, enabling the processing and display of traffic information for informed automated driving decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If automated driving control is implemented using only basic traffic information (congestion, traffic restrictions), then automated driving can be executed, but the information utility is insufficient for effective decision-making
Solution Approach 1:
The patent introduces a communication section as an intermediary component that enables vehicles to exchange surrounding environment information and automated driving status with other devices. This mediator allows the system to access additional information sources beyond basic traffic data, thereby improving information utility without requiring fundamental changes to the automated driving controller architecture.
Solution Approach 2:
The communication section is designed with multi-functionality, serving both to transmit automated driving status information and to receive surrounding environment information from other vehicles. This universal component addresses the information insufficiency problem while avoiding the need for separate dedicated systems for each function, thus limiting the increase in system complexity.
2Loss of information
If vehicle surrounding information and automated driving status are shared with other devices, then information utility for automated driving is improved, but communication and data processing requirements increase
Solution Approach 1:
The patent extracts and transmits only the essential elements of surrounding environment information and automated driving status that are most useful for other vehicles' decision-making. By selecting and transmitting only critical data elements rather than complete raw data, the system improves information sharing capability while minimizing communication energy consumption.
3Reliability
If real-time traffic information is processed and displayed for automated driving decisions, then driving safety and efficiency are improved, but system response time and processing load increase
Solution Approach 1:
The system performs preliminary processing of received surrounding environment information and automated driving status data, organizing and filtering them before they are used for automated driving decisions. By preparing the information in advance rather than processing raw data in real-time during critical decision moments, the system improves driving safety while reducing actual response time.

AI summary
A vehicle control system includes: a surroundings information acquisition section configured to acquire vehicle surroundings information; an automated driving controller configured to execute automated driving in which at least one of speed control or steering control is controlled automatically based on the vehicle surroundings information acquired by the surroundings information acquisition section; a communication section configured to directly or indirectly communicate with another device; and a communication controller configured to transmit the vehicle surroundings information and information indicating an execution status of the automated driving to the other device using the communication section.
