Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving, existing technologies fail to effectively manage situations where vehicles deviate from controlled behavior, leading to potential safety hazards due to inadequate prediction and responsibility determination for accidents.
Innovation Solution
A vehicle control apparatus and method that includes a running planning unit, an action prediction unit, and a responsibility determination unit to predict deviations in vehicle behavior and determine potential accident responsibility, enhancing safety by adjusting safe distances and preventing collisions.

Engineering Contradiction Analysis
1Reliability
If autonomous driving control is implemented without action prediction, then device complexity is reduced, but reliability deteriorates due to inability to predict deviation behaviors and determine accident responsibility
Solution Approach 1:
The action prediction unit performs preliminary prediction of deviation behaviors before actual accidents occur. By predicting potential actions of the subject vehicle and other moving bodies in advance, the system prepares for safety issues proactively, enabling responsibility determination and preventive control before harmful events happen.
Solution Approach 2:
The control system is segmented into distinct functional units: running planning unit, action prediction unit, and responsibility determination unit. Each unit handles specific tasks independently - the running planning unit calculates candidate routes, the action prediction unit predicts deviation behaviors, and the responsibility determination unit assesses accident responsibility, allowing modular complexity management while improving overall reliability.
2Reliability
If action prediction and responsibility determination are added to autonomous driving control, then reliability improves through better safety management, but device complexity increases due to additional prediction and determination units
Solution Approach 1:
The action prediction unit serves multiple functions simultaneously: it predicts deviation behaviors of the subject vehicle, predicts actions of other moving bodies, provides input for responsibility determination, and supports running plan optimization. This multi-functionality reduces the need for separate dedicated components for each function, managing complexity while improving reliability.
Solution Approach 2:
The responsibility determination unit feeds back accident responsibility assessments to the running planning unit, which adjusts candidate routes and running plans accordingly. This feedback loop enables continuous improvement of safety management by learning from predicted scenarios and adjusting control strategies, enhancing reliability without requiring completely separate control systems.

AI summary
A vehicle control apparatus is mounted in a subject vehicle provided with a running planning unit configured to calculate one or more candidate routes on which the subject vehicle is to travel. The vehicle control apparatus predicts an action of a prediction target moving body that includes the subject vehicle and at least one moving body present in a vicinity of the subject vehicle.
