Vehicle Risk Communication for Hazardous Load Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-everything communication technologies do not adequately address the risk of accidents caused by vehicles transporting dangerous objects, as drivers may not be aware of the contents being transported, leading to potential collisions and fires.
Innovation Solution
A vehicle system that determines the degree of risk based on the type or weight of the object being transported, communicates this risk to nearby vehicles, and controls driving assistance functions to prevent accidents by adjusting speed, inter-vehicle distance, collision warning time, and lateral position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X communication technology is applied to enable information exchange between vehicles, then driving safety can be improved through awareness of surrounding conditions, but drivers still cannot know the specific contents (dangerous objects) being transported by other vehicles
Solution Approach 1:
The patent introduces an intermediary system consisting of a camera mounted on the transporting vehicle and a communication unit that transmits captured images to nearby vehicles. This intermediary mechanism enables other drivers to visually identify dangerous objects being transported without requiring direct access to the transporting vehicle's cargo area, thereby resolving the information asymmetry problem while maintaining driving safety improvements from V2X communication.
2Productivity
If a vehicle transports dangerous objects without communicating risk information, then the transporting vehicle can maintain normal speed and route, but nearby vehicles may collide with falling objects or the transporting vehicle due to lack of awareness
Solution Approach 1:
The patent implements preliminary action by having the transporting vehicle proactively capture images of dangerous objects with a camera and transmit risk information to nearby vehicles before any accident can occur. This advance warning system allows other drivers to take preventive measures such as increasing following distance or avoiding the area, thereby eliminating collision risks and fire hazards while the transporting vehicle maintains its normal operation.
Solution Approach 2:
The system establishes a feedback loop where the transporting vehicle continuously monitors its surroundings and communicates risk information to nearby vehicles through the communication unit. This real-time feedback enables dynamic adjustment of driving behavior by nearby vehicles in response to the transported dangerous objects, preventing accidents while allowing the transporting vehicle to maintain productivity.
3Reliability
If risk information is transmitted to nearby vehicles, then accidents can be prevented, but the system requires additional components (camera, communication unit) and processing
Solution Approach 1:
The patent applies universality by designing a system where the camera and communication unit can serve multiple functions: capturing images for risk assessment, transmitting information to multiple nearby vehicles simultaneously, and potentially recording evidence for accident investigation. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while achieving comprehensive accident prevention.

AI summary
Disclosed herein is a vehicle including: a communication unit configured to communicate with a nearby vehicle; a memory configured to store at least one piece of degree-of-risk information of first degree-of-risk information corresponding to each type of a pre-designated load or second degree-of-risk information corresponding to each weight of a pre-designated load; and a processor communicatively or electrically connected to the communication unit and the memory, wherein the processor determines a degree of risk of an object loaded in the vehicle based on information on at least one of a type or weight of the object loaded in the vehicle and the at least one piece of degree-of-risk information stored in the memory and controls the communication unit such that information including the determined degree of risk is transmitted to the nearby vehicle.
