Dynamic Priority Distribution for Vehicle Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems face challenges in dynamically distributing vehicle information due to fixed priority level calculations and inability to adapt to changes in driving assistance applications or vehicle states, leading to processing delays and inadequate timing for providing assistance.
Innovation Solution
A driving assistance device with environmental information management and dynamic distribution control means that receives and prioritizes vehicle information based on changing environmental conditions and application needs, using a system with communication, environmental information management, and distribution control units to ensure timely and relevant information distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If vehicle information is received simultaneously from multiple peripheral vehicles, then the system can recognize a wider area and more vehicles, but processing delay occurs when attempting to process all vehicle information in the order received
Solution Approach 1:
The patent applies preliminary action by predicting the future proximity of vehicles in advance and pre-establishing priority levels before actual processing is needed. The system calculates predicted positional relationships and pre-assigns priority levels to vehicle information based on anticipated importance, so that when information needs to be processed, it is already organized in the correct order, eliminating processing delays.
2Ease of operation
If a fixed priority level calculation method is used, then distribution control can be implemented, but distribution control in accordance with requirements cannot be carried out when multiple driving assistance applications desire separate vehicle information
Solution Approach 1:
The patent applies dynamics by making the priority level calculation method changeable and adaptable. Instead of a fixed calculation method, the system allows different driving assistance applications to set or influence priority levels according to their specific requirements. The priority levels dynamically adjust based on application needs, vehicle states, and environmental conditions, enabling each application to receive appropriately prioritized information.
Solution Approach 2:
The patent applies parameter changes by allowing the priority level parameters to be modified based on different applications and conditions. The system changes the calculation parameters of priority levels according to the specific needs of each driving assistance application, vehicle state, and environmental context, enabling flexible and adaptive information distribution control.
3Adaptability or versatility
If a region of focus is changed in accordance with cruising state, then priority level can be dynamically changed, but there is no means that sets the region of focus from an exterior of the distribution control unit, so the priority level calculation method cannot be changed when vehicle information to be distributed changes
Solution Approach 1:
The patent applies universality by creating a standardized environmental information management mechanism that serves multiple functions. The same management system handles both the region of focus definition and the priority level calculation, allowing external entities to influence priority levels through environmental information without requiring separate complex control mechanisms for each function.

AI summary
A plurality of items of environmental information, which are used for distribution control of plural items of vehicle information that are received using wireless communication by an external communication device from a plurality of surrounding vehicles, are made into an environmental information list by an environmental information setting mechanism and managed. Based on the environmental information list, for the plural items of vehicle information received by the external equipment communication device, selection is performed using a dynamic filtering part of a dynamic distribution controller and distribution control is performed using the priority level according to a dynamic priority controller. A driving assistance device that receives this information assists a driver in driving, and environmental information set in the environmental information list is generated.
