Drive Support Device Adapting to Driver Proficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive supporting devices fail to effectively support drivers unfamiliar with local traffic signal systems, leading to misunderstandings and inadequate support when driving in foreign countries due to varying signal cycles and driving rules.
Innovation Solution
A drive supporting device that acquires traffic signal information and adjusts its support based on the driver's proficiency level in the current region, using a proficiency level determining unit to assess the driver's familiarity with local rules and signal systems, thereby providing tailored information and control adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive supporting device uses a fixed method to provide traffic signal information based on the driver's home country traffic signal system, then the driver can understand the information correctly in their familiar environment, but the driver cannot appropriately use the drive support function when driving in a foreign country with different traffic signal systems
Solution Approach 1:
The drive supporting device dynamically adjusts its support method based on the driver's location and proficiency level. When the driver enters a foreign country, the system detects the change in traffic signal system characteristics and modifies its information provision strategy accordingly, transitioning from a static to a dynamic adaptation approach
Solution Approach 2:
The system changes the parameters of drive support by adjusting the proficiency level determination based on geographic location. Different regions have different proficiency level thresholds and information provision methods, allowing the system to adapt to various traffic signal systems by modifying its operational parameters
2Productivity
If the drive supporting device provides detailed traffic signal information assuming the driver is familiar with the local system, then the support is effective for local drivers, but foreign drivers misunderstand the provided information
Solution Approach 1:
The drive supporting device applies different information provision qualities to different driver groups. For drivers with high proficiency in the current region, it provides concise information. For drivers with low proficiency (foreign drivers), it provides more detailed and explanatory information, making the information quality adaptable to the user's background
Solution Approach 2:
The system uses feedback from the proficiency level determination unit to adjust its information provision. By continuously assessing whether the driver is familiar with the current traffic signal system, the system modifies its information delivery to prevent misunderstanding while maintaining effectiveness
3Device complexity
If the drive supporting device uses a single drive support method for all drivers, then the system is simple to implement, but it cannot provide appropriate support for drivers unfamiliar with the local traffic signal system
Solution Approach 1:
The system performs preliminary assessment of the driver's proficiency level with the current traffic signal system before providing drive support. By determining the proficiency level in advance, the system can select the appropriate support method without requiring complex real-time adjustments during driving

AI summary
A drive supporting device includes a GPS, a front camera, and a communication device that acquire traffic signal information related to the time-series on/off state of a traffic signal and an ECU that supports the driving of a vehicle on the basis of the traffic signal information acquired by, for example, the communication device. The ECU changes a driver support aspect on the basis of the level of proficiency of the driver of the vehicle in a region in which the vehicle is currently located. In this way, even when the driver is in a strange place, it is possible to appropriately support the driving of the vehicle.
