Driving Assist Apparatus Adapting to Regional Traffic Rule Deviations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assist systems are ineffective when a mobile object around the host-vehicle violates traffic rules, as they rely on predefined rules that may not be observed in specific regions, leading to safety deterioration.
Innovation Solution
A driving assist apparatus that acquires and adapts to the probability of traffic rule observation in each region, using a traffic rule acquisition unit, region acquisition unit, and traffic rule correction unit to prioritize the rule most likely observed, thereby performing appropriate assistive control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving assist control is performed on the basis of predefined traffic rules, then the host-vehicle can observe traffic rules, but the control becomes ineffective when mobile objects around the host-vehicle violate traffic rules, leading to safety deterioration
Solution Approach 1:
The system dynamically adjusts traffic rules based on the probability that mobile objects will actually observe them in specific regions. Instead of using fixed predefined rules, the system modifies traffic rules according to regional characteristics and observed behavior patterns, allowing the control system to adapt to actual traffic conditions where rules may be violated.
Solution Approach 2:
The system changes the parameters of traffic rules by introducing probability values that reflect the likelihood of mobile objects observing rules in different regions. This allows the driving assist control to account for regional variations in rule compliance, transforming static traffic rules into probabilistic, region-specific guidelines that better predict actual mobile object behavior.
2Reliability
If driving assist is performed on the basis of probability that traffic rules are observed in each region, then appropriate assist can be provided even when rules are violated, but the system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing probability values for traffic rule observation in different regions before actual driving assist control is needed. This allows the complex probability-based adjustments to be prepared in advance, reducing the computational burden during real-time control operations and simplifying the overall system architecture.

AI summary
A driving assist apparatus 1 that performs driving assist on the basis of a traffic rule of a mobile object includes a traffic rule acquisition unit 11, 12, and 13 acquiring a traffic rule which a mobile object is highly likely to observe in an arbitrary region, and performs driving assist on the basis of the traffic rule acquired by the traffic rule acquisition unit. In particular, the driving assist apparatus includes a region acquisition unit 13 acquiring a traffic rule deviation region where a defined traffic rule in an arbitrary region does not conform to the traffic rule acquired by the traffic rule acquisition unit, or a traffic rule correction unit correcting the traffic rule acquired by the traffic rule acquisition unit when a defined traffic rule in an arbitrary region does not conform to the traffic rule acquired by the traffic rule acquisition unit.
