Driving Assistance Apparatus Traffic Light Timing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems fail to provide comfortable and effective driving operation support, as drivers may struggle to follow recommended driving operations due to varying traffic situations, leading to potential adverse effects on traffic flow and driver comfort.
Innovation Solution
A driving assistance apparatus equipped with a notification system, including a display and an electronic control unit, acquires traffic light information and vehicle position data to derive recommended driving instructions, such as target vehicle speed ranges and deceleration instructions, and determines if the driver performs the operations accordingly, displaying remaining time until traffic light changes to enhance driver understanding and compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the timing of deceleration operation is notified to the driver, then the vehicle can pass through the intersection in a non-stop manner, but the driver may not be able to perform the driving operation due to various traffic situations
Solution Approach 1:
The system continuously monitors actual driving operations and compares them with recommended operations. When the driver deviates from recommended operations due to traffic situations, the system provides feedback by displaying remaining green light time information, enabling the driver to adjust operations accordingly while maintaining intersection throughput efficiency
Solution Approach 2:
The notification system dynamically adapts its behavior based on driver response. When recommended operations are not followed, the system activates additional notifications about remaining green light time, making the system flexible and adaptive to varying driver capabilities and traffic conditions
2Productivity
If driving operation assistance is provided to ensure non-stop passage through intersection, then productivity is improved, but driver comfort may be reduced due to inability to perform operations
Solution Approach 1:
The remaining green light time information acts as an intermediary element between the traffic light control system and the driver. It provides drivers with additional contextual information that mediates the conflict between maintaining high intersection throughput and ensuring driver comfort, allowing drivers to make informed decisions without feeling constrained by rigid recommendations
3Ease of operation
If information on recommended driving is notified to the driver, then driving operation guidance is provided, but the driver may not understand the timing and urgency of operations
Solution Approach 1:
The system displays remaining green light time information in advance before the green light expires. This preliminary information provision allows drivers to plan and execute deceleration or acceleration operations at appropriate times, understanding the urgency and timing requirements without needing to react to last-minute notifications

AI summary
A driving assistance apparatus including a notification part including a display portion and a microprocessor. The microprocessor is configured to perform deriving a recommended driving recommended to a driver based on traffic light information and position information, controlling the notification part so as to notify the driver of information on the recommended driving, and determining whether the driver performs a driving operation according to the information on the recommended driving after the information on the recommended driving is notified. The microprocessor is configured to perform the controlling including controlling the notification part so that the information on a remaining time for switching of the traffic light included in the traffic light information is displayed on the display portion, when it is determined that the driver performs the driving operation according to the information on the recommended driving.
