Obstacle Detection Relay Between Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers may fail to detect obstacles in their lane due to restricted visibility, leading to potential collisions, especially when the sight of a following vehicle is blocked by a leading vehicle.
Innovation Solution
A method and apparatus for obstacle-in-lane warning, where a first vehicle detects an obstacle and transmits information to a second vehicle, enabling the second vehicle to perform an early warning and prevent collisions by alerting the driver to the presence of the obstacle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a driver relies on direct visual detection of obstacles, then the detection is straightforward and requires no additional systems, but the driver cannot spot obstacles fast enough when line-of-sight is hindered by the leading vehicle
Solution Approach 1:
The patent introduces an intermediary detection system consisting of sensors on the leading vehicle and communication modules that transfer obstacle information to the following vehicle. This intermediary system bridges the visibility gap created by the leading vehicle, allowing the following driver to detect obstacles without direct line-of-sight while maintaining system reliability.
Solution Approach 2:
The patent replaces the purely mechanical/visual detection method with an electronic information transmission system. Instead of relying on the driver's physical line-of-sight, the system uses sensors, processors, and communication modules to electronically transmit obstacle information, substituting mechanical visual detection with electronic sensing and data transmission.
2Loss of information
If the following vehicle uses its own sensors to detect obstacles, then it has independent detection capability, but it cannot detect obstacles in the blind area blocked by the leading vehicle
Solution Approach 1:
The patent merges the detection capabilities of the leading vehicle with the following vehicle through information sharing. The sensor data from the leading vehicle is combined with the following vehicle's own sensor data, creating a merged information set that provides comprehensive obstacle detection coverage that neither vehicle could achieve alone.
Solution Approach 2:
The patent makes the leading vehicle's detection system serve multiple functions: it detects obstacles for its own safety while simultaneously providing detection data to following vehicles. This multi-functionality allows the same sensor system to benefit multiple vehicles, reducing the need for redundant sensor installations on each vehicle.
3Reliability
If obstacle detection is performed only when the driver has direct visibility, then the system is simple and responsive, but collisions cannot be prevented when the driver's sight is blocked
Solution Approach 1:
The patent performs preliminary obstacle detection using the leading vehicle's sensors before the following vehicle's driver would even become aware of the obstacle. The system detects and transmits obstacle information in advance, providing early warning that allows the following driver to prepare for potential hazards before direct visibility is needed.
Solution Approach 2:
The patent establishes a feedback loop where obstacle detection information flows from the leading vehicle to the following vehicle in real-time. This continuous feedback mechanism ensures that the following driver receives updated obstacle information dynamically, allowing for timely responses to changing road conditions even when direct visibility is blocked.

AI summary
Provided are a method, an apparatus and a device for obstacle in lane warning. The method includes receiving information of an obstacle in a front lane of a first vehicle, where the first vehicle is in front of a second vehicle; and performing an obstacle warning on the second vehicle according to the information of the obstacle. The second vehicle receives the information of the obstacle, and performs the obstacle warning on the second vehicle according to the information of the obstacle to prevent the second vehicle from failing to detect the obstacle in a blind area when the sight of the second vehicle is blocked by the first vehicle; the front vehicle notifies the subsequent vehicle of the obstacle in the lane immediately, which facilitates the driver to handle the situation in advance, improves the vehicle's ability to sense the obstacle and prevents the collision from occurring.
