Solution Overview
Problem
Existing vehicle control systems face challenges in smoothly switching from automatic steering mode to manual steering mode due to the limited detection range of autonomous sensors, which requires hasty driver intervention and may lead to unsafe transitions.
Innovation Solution
A vehicle control device that utilizes information from a wireless communication system, such as ITS, to determine when to switch from automatic steering mode to manual steering mode, allowing for earlier and smoother transitions by considering a wider range of information beyond the autonomous sensor's detection limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous sensors are used to detect driving conditions for automatic steering mode switching, then the system can operate autonomously, but the limited detection range causes hasty switching requirements and reduces safety
Solution Approach 1:
The patent combines autonomous sensor detection with wireless communication system information to create a hybrid detection approach. The wireless device provides additional vehicle state and environmental information that complements the autonomous sensor data, enabling more reliable automatic steering mode switching decisions while maintaining automation.
Solution Approach 2:
The system performs preliminary determination of mode switching necessity by receiving and processing wireless communication information in advance. This allows the system to prepare for mode transitions earlier and more smoothly, reducing hasty switching requirements and improving transition safety.
2Device complexity
If autonomous sensors operate independently without external communication, then the system structure is simple, but the detection range is limited and mode switching timing is delayed
Solution Approach 1:
The wireless communication system acts as an intermediary that provides additional information about vehicle state and environment. This intermediary enables earlier detection of conditions requiring mode switching, reducing response time delays without significantly complicating the overall system structure.
3Device complexity
If the system relies solely on autonomous sensor data, then information processing is straightforward, but the detection accuracy and awareness of surrounding conditions are insufficient
Solution Approach 1:
The patent merges autonomous sensor data with wireless communication information to enhance detection accuracy. The combination of these information sources provides more comprehensive awareness of surrounding conditions and vehicle state, improving measurement precision without excessive complexity increase.

AI summary
A method for controlling an apparatus for a first vehicle includes: receiving first positional information including a current position of the first vehicle, a traveling direction of the first vehicle, and a traveling speed of the first vehicle; receiving second positional information including a current position of a second vehicle, a traveling direction of the second vehicle, and a traveling speed of the second vehicle; estimating a future position of the first vehicle on the basis of the first positional information; estimating a future position of the second vehicle on the basis of the second positional information; determining whether a distance between the future position of the first vehicle and the future position of the second vehicle is shorter than a threshold value, and notifying a driver of the first vehicle of a result of the determination when the distance is shorter than the threshold value.
