Vehicle Overtaking Control Using Front-Vehicle Visibility Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In situations where a rear vehicle needs to overtake a front vehicle on a narrow road, the rear vehicle may not be aware of oncoming vehicles due to limited field of view, leading to potential accidents.
Innovation Solution
A vehicle control method and device that determines whether a rear vehicle intends to overtake by analyzing road conditions, approach conditions, intention conditions, and risk conditions, and then provides the rear vehicle with information on safe overtaking points through displayed content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the rear vehicle crosses the center line to overtake the front vehicle, then the rear vehicle can pass the front vehicle, but the rear vehicle may collide with an oncoming vehicle due to limited field of view
Solution Approach 1:
The front vehicle performs preliminary actions by detecting the rear vehicle's overtaking intention through sensors (cameras, radar) before the actual overtaking occurs. The front vehicle then transmits advance warning information about oncoming vehicles and road conditions to the rear vehicle, allowing the rear vehicle to make informed decisions about whether to proceed with overtaking.
Solution Approach 2:
The front vehicle acts as an intermediary between the oncoming vehicle (which the rear vehicle cannot see) and the rear vehicle attempting to overtake. Through V2V communication, the front vehicle relays critical information about the front situation, including the presence of oncoming vehicles, to the rear vehicle, thereby mediating the safety of the overtaking maneuver.
2Reliability
If the rear vehicle maintains a safe distance from the front vehicle, then the risk of collision is reduced, but the rear vehicle cannot overtake efficiently
Solution Approach 1:
The system implements feedback by continuously monitoring the rear vehicle's position, speed, and behavior through sensors. When the rear vehicle exhibits overtaking intentions (such as moving toward the center line or increasing speed), the front vehicle receives this feedback and responds by transmitting appropriate warning or guidance information about the front situation, enabling dynamic adjustment of the rear vehicle's overtaking decision.
3Loss of information
If the front vehicle provides continuous information to the rear vehicle, then the rear vehicle can make informed overtaking decisions, but the communication system becomes more complex
Solution Approach 1:
The system extracts only the most critical information needed for safe overtaking decisions, such as the presence of oncoming vehicles, road conditions, and safe overtaking zones, rather than transmitting all possible data. This selective extraction of essential information reduces communication overhead and system complexity while still providing the rear vehicle with sufficient data to make informed decisions.

AI summary
An embodiment vehicle control device includes one or more processors and a non-transitory storage device storing a program to be executed by the one or more processors, the program including instructions to receive information for determination, determine, based on the received information, whether an overtaking condition is satisfied, whether yielding is possible, whether there is an oncoming vehicle, or whether a rear vehicle attempts to overtake a vehicle, control a display device to output content determined based on a determination result for providing a front situation and a vehicle control state to the rear vehicle and an occupant of the vehicle, and control a maneuver of the vehicle based on the determination result.
