Automated Driving Control Device for Intersection Turn Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving vehicle technologies face complexity in detecting and interpreting gestures for permission to turn right across an intersection, leading to potential improper detection and increased risk of collisions.
Innovation Solution
A control device that activates a travel start button when a vehicle is stopped due to an obstacle, allowing an onboard person to manually initiate a right or left turn, disabling collision damage reduction functions during the turn and re-enabling them after a predetermined period or distance, thereby simplifying the detection process and ensuring safe intersection navigation.

Engineering Contradiction Analysis
1Extent of automation
If gesture detection is used to detect permission for right turn, then automated driving can proceed, but detection complexity increases and reliability decreases
Solution Approach 1:
The patent extracts the gesture detection function from the automated driving control system. Instead of using gesture detection to control automated driving, the system separates these functions: gesture detection remains for driver intent recognition, while a dedicated travel start button handles the permission signal for turning operations, simplifying the overall detection processing.
Solution Approach 2:
The travel start button serves multiple functions: it acts as both the activation signal for automated driving and the permission signal for turning operations at intersections. This multi-functionality eliminates the need for separate detection mechanisms, reducing system complexity while maintaining automated driving capability.
2Extent of automation
If gesture detection is used to detect permission for right turn, then automated driving can proceed, but detection accuracy decreases leading to improper detection
Solution Approach 1:
The patent introduces the travel start button as an intermediary device between the driver and the automated driving system. This physical button provides unambiguous input that is easier to detect accurately than gestures, serving as a reliable mediator that confirms driver intent without the ambiguity inherent in gesture recognition.
3Reliability
If collision damage reduction function is always active, then safety is improved, but it may prevent necessary turns by restricting movement
Solution Approach 1:
The patent applies dynamic control to the collision damage reduction function. The function's activation state changes based on the operational context: it is deactivated when the travel start button is pressed (indicating intentional turning operation) and reactivated after the turning maneuver is completed. This dynamic adjustment allows the system to balance safety with operational flexibility.
Solution Approach 2:
The system performs preliminary action by deactivating the collision damage reduction function before the turning operation begins (when travel start button is pressed) and reactivating it after the turn is completed. This timing ensures that the safety function does not interfere with the intended maneuver while maintaining protection during normal operation.

AI summary
The present disclosure relates to control performed in a case where a vehicle is to turn right or left at an intersection. A control device causes the vehicle to carry out a right turn or left turn when a travel start button for starting travel from a stopped state is manipulated while the vehicle is in a stopped state due to presence of a target to be paid attention to during travel, such as a vehicle in an opposite lane or a pedestrian.
