Vehicle Microcomputer Traffic Violation Severity Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle systems fail to effectively manage a wide range of traffic regulations and provide flexible, location-dependent warnings for drivers, limiting their understanding of the severity of violations and potential consequences, which can lead to unsafe driving practices.
Innovation Solution
A motor vehicle device equipped with a computing unit that compares driving behavior data with stored traffic rules, determines the severity of violations, and generates control signals to alert drivers or assist systems, incorporating a database of fines and user-defined limit values, allowing for flexible adaptation to various traffic regulations and location-specific rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor vehicle system monitors and warns about traffic regulations, then driver awareness of violations is improved, but the system complexity increases due to multiple sensors and processing units
Solution Approach 1:
The system integrates multiple monitoring functions (speed, distance, traffic sign recognition, lane keeping) into a single comprehensive traffic rule monitoring device that can handle various types of violations uniformly through a centralized evaluation process
Solution Approach 2:
The system introduces an intermediary evaluation unit that receives data from multiple sensors and translates them into traffic rule compliance assessments, acting as a mediator between raw sensor data and driver warnings
2Loss of information
If the system provides detailed information about violation severity and consequences, then driver understanding is improved, but the information processing load increases
Solution Approach 1:
The system pre-stores catalog of fines and consequence information in memory, preparing all possible violation details in advance so that when a violation occurs, the information can be immediately retrieved and presented without real-time processing delays
Solution Approach 2:
The system provides continuous feedback to the driver about their compliance status, violation severity, and potential consequences, creating a closed-loop information system that helps drivers understand and adjust their behavior
3Reliability
If the system automatically transfers control signals to driver assistance systems, then safety is improved, but the loss of driver control increases
Solution Approach 1:
The system applies partial automation by providing warnings and information first, and only transfers control to driver assistance systems when violations are severe or persistent, maintaining driver control for minor infractions while ensuring safety for serious violations

AI summary
A microcomputer (10) produces a parameter (18) related to the gravity of traffic violation based on data e.g. traffic rules, geographical location, maximum speed limit, traffic routes, stored in a database. The microcomputer then produces signals for motor vehicle driving control or driving assist based on the parameter. A signal unit (22) alerts the driver of possible consequences resulting from traffic violation. The parameter may be in form of traffic fines using a penalty catalog in the database.
