Automated Passing Control Adjusting Conditions for Route Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems often fail to perform passing control in a manner that aligns with the occupant's intentions, as they may attempt to pass a preceding vehicle when the occupant does not want to or vice versa, leading to a disconnect between the system's actions and the occupant's preferences.
Innovation Solution
A vehicle control apparatus that recognizes the surrounding environment and performs passing control based on specific conditions related to the relative speed and type of the preceding vehicle, while adjusting these conditions when the continuity of the host vehicle's route decreases, such as approaching a branch point, to curb passing control and align with the occupant's likely preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If passing control is performed based on relative speed and vehicle type conditions, then the host vehicle can efficiently overtake preceding vehicles, but the system may attempt to pass when the occupant does not want to or vice versa
Solution Approach 1:
The system incorporates feedback by detecting occupant operations (accelerator depression, brake operation, steering input) and using this information to adjust passing control conditions. The driving controller monitors occupant actions in real-time and modifies passing control execution based on detected operations, creating a feedback loop that aligns automated decisions with occupant intentions.
Solution Approach 2:
The passing control conditions are made dynamic rather than fixed. The system adjusts passing control thresholds and parameters based on real-time detection of occupant operations. When aggressive operations are detected, the system becomes more willing to pass; when cautious operations are detected, the system becomes more conservative, creating a dynamic adaptation to occupant state.
2Productivity
If the host vehicle changes lanes to pass a preceding vehicle, then the host vehicle can overtake the preceding vehicle, but the host vehicle cannot return to the previous lane when the road environment or travel situation does not permit
Solution Approach 1:
The system performs preliminary assessment of lane change conditions before executing passing maneuvers. The driving controller evaluates road environment and travel situation in advance, checking whether returning to the previous lane is possible. This preliminary action prevents unsafe lane changes by verifying conditions beforehand.
Solution Approach 2:
The system continuously monitors lane change conditions and provides feedback on whether passing control should be executed. The driving controller detects current road environment and adjusts passing control based on this feedback, ensuring that lane changes are only performed when safe and appropriate conditions exist.
3Stability of the object's composition
If the host vehicle is caused to keep the current lane when it cannot return to the previous lane, then the host vehicle maintains stable travel, but the occupant's desire to pass the preceding vehicle cannot be fulfilled
Solution Approach 1:
The system provides feedback to the occupant when passing control is curbed due to road environment constraints. The driving controller communicates lane keeping decisions back to the occupant, explaining why passing cannot be executed. This feedback maintains occupant awareness while ensuring stable travel.
Solution Approach 2:
The system takes preliminary anti-action by preventing passing maneuvers when road environment conditions indicate it would be unsafe. The driving controller proactively curbs passing control before the occupant can initiate an unsafe lane change, preventing potential hazards while maintaining stable travel.

AI summary
A vehicle control apparatus includes a recognizer which is configured to recognize a surrounding environment of a host vehicle and a driving controller which is configured to perform automated driving on the basis of a recognition result of the recognizer, wherein the driving controller is configured to perform passing control of causing the host vehicle to pass a preceding vehicle if at least one of a first condition according to a relative speed of the host vehicle with respect to the preceding vehicle and a second condition according to a type of the preceding vehicle is satisfied when the recognizer recognizes the preceding vehicle, and is configured to curb the passing control by changing at least one of the first condition and the second condition when a continuity of a first route on which the host vehicle is traveling decreases.
