Solution Overview
Problem
There is a high likelihood of collision accidents between vehicles on curved roads, particularly when oncoming two-wheeled vehicles run off into the traveling lane of another vehicle.
Innovation Solution
A wireless communication device is mounted on vehicles, equipped with an input circuit to connect with a lean angle detection circuit and an output circuit to repeatedly transmit wireless signals containing the vehicle's position, speed, and lean angle at predetermined intervals.

Engineering Contradiction Analysis
1Reliability
If conventional sensor-based detection is used to monitor surrounding vehicles, then basic presence detection is achieved, but collision risk on curved roads cannot be effectively suppressed
Solution Approach 1:
The patent introduces wireless communication as an intermediary between vehicles to exchange lean angle and position information. This mediator enables vehicles to share critical state data that conventional sensors cannot detect, allowing receiving vehicles to predict potential collisions on curved roads by analyzing the lean angles and positions of oncoming vehicles.
Solution Approach 2:
The system performs preliminary detection of collision risk by continuously monitoring and exchanging lean angle information before actual collisions occur. By analyzing lean angle data in advance, the system can predict when a vehicle might run off the road on a curve and take preventive measures, rather than reacting after the collision has already happened.
2Reliability
If lean angle detection and wireless transmission are implemented, then collision risk on curved roads is reduced, but device complexity increases
Solution Approach 1:
The wireless communication device performs multiple functions: it detects lean angle through the connected detection circuit, determines vehicle position based on lean angle data, transmits this information wirelessly to other vehicles, and receives similar data from incoming vehicles. By consolidating these functions into a single multi-functional device, the patent reduces overall system complexity compared to having separate components for each function.
