Vehicle Obstacle Avoidance Alerts for Distracted Driver Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to provide appropriate notifications to occupants based on the vehicle's situation, particularly when a driver is in a distracted state and an obstacle is present, which can lead to inadequate safety measures.
Innovation Solution
A vehicle control system that includes a recognizer to identify the vehicle's surroundings and driver state, a controller for executing driving controls like steering and deceleration, and a notifier that provides tiered notifications (first and second notifications) based on the vehicle's proximity to an obstacle and the driver's responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If notification control is not implemented before avoidance control, then the system complexity is reduced, but the appropriateness of notifications to occupants deteriorates
Solution Approach 1:
The notification system is segmented into multiple notification stages (first notification, second notification, third notification) with different notification methods and intensities. This segmentation allows the system to provide appropriate notifications for different urgency levels without requiring a completely complex decision-making structure, as each stage has predefined notification characteristics.
Solution Approach 2:
The system performs preliminary notification actions before executing avoidance control. By issuing notifications in advance (first notification before avoidance control, second notification before or during avoidance control), the system prepares the occupant for upcoming maneuvers, improving notification appropriateness without adding complex real-time decision-making requirements.
2Reliability
If multiple notification stages are implemented, then the notification appropriateness is improved, but the device complexity increases
Solution Approach 1:
Different notification methods are applied locally to different stages and situations. The first notification uses gentle methods (display only), the second notification uses stronger methods (display and sound), and the third notification uses the strongest methods (display, sound, and vibration). This local differentiation of notification quality allows appropriate notifications without requiring a single complex notification mechanism.
Solution Approach 2:
The notification system dynamically adapts its characteristics based on the situation. The notification method, intensity, and timing are dynamically adjusted according to whether avoidance control is needed, the urgency of the situation, and the occupant's response. This dynamic behavior allows the system to provide appropriate notifications without requiring a static complex structure.
3Device complexity
If the system waits for avoidance control execution before notifying occupants, then the notification timing is simplified, but the safety effectiveness deteriorates
Solution Approach 1:
The system issues notifications in advance before executing avoidance control. The first notification is issued before avoidance control to alert the occupant of potential danger, and the second notification is issued before or during avoidance control to confirm the maneuver. This preliminary notification approach improves safety effectiveness by giving the occupant advance warning without complicating the timing logic.
Solution Approach 2:
The system takes preliminary anti-action by notifying the occupant before the avoidance maneuver occurs, allowing the occupant to mentally prepare and potentially take additional actions. This preliminary warning prevents the occupant from being surprised by sudden maneuvers, improving overall safety effectiveness without requiring complex timing coordination.

AI summary
A vehicle control device of an embodiment includes a recognizer that recognizes a surrounding situation of a vehicle; a driving state detector that detects a driving state of a driver; a controller that executes, when an obstacle is present in front of the vehicle and the driver is in a distracted driving state, driving control suitable for the obstacle; and a notifier that issues a notification when the driving control is executed. The notifier includes a first notification which is notified at the time of execution of first driving control including steering control, and a second notification which is notified at the time of execution of second driving control executed in a state in which the vehicle has approached further toward the obstacle from in the first driving control. The second notification is issued when a particular driving support function is operated within a predetermined time from the first notification.
