Host Vehicle Warning System for Tailgating Collision Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems for vehicles cannot effectively warn drivers of third-party vehicles without such systems of impending collisions, as they rely on communication between vehicles, which is not possible when the third-party vehicle lacks a driver assistance system.
Innovation Solution
A method where a host vehicle with a driver assistance system uses environmental sensors to detect an imminent collision and alerts the third-party vehicle driver through visual or acoustic signals, such as flashing lights or sounds, without requiring communication between the vehicles, allowing the third-party driver to take preventive measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance systems use vehicle-to-vehicle communication to warn of collisions, then the warning system can provide precise collision information, but the system cannot warn drivers of third-party vehicles without such communication capabilities
Solution Approach 1:
The patent uses the host vehicle's existing communication infrastructure as an intermediary to transmit collision warning information to the third-party vehicle driver. Instead of requiring direct communication between the detection system and the third-party vehicle, the host vehicle's driver assistance system acts as a mediator, receiving sensor data and relaying warning information through visible or audible signals that any driver can perceive, thereby bridging the communication gap between equipped and unequipped vehicles.
2Measurement precision
If the host vehicle uses existing sensor systems to detect collisions, then the system can identify imminent collision risks, but it cannot effectively warn third-party drivers who lack driver assistance systems
Solution Approach 1:
The patent segments the warning function from the detection function. The host vehicle's driver assistance system performs the complex sensor processing and collision prediction, while the warning output is segmented into simple, universally perceptible signals such as visual indicators or audible alerts. This segmentation allows the sophisticated detection capabilities to remain in the equipped vehicle while the warning mechanism becomes accessible to any driver regardless of their vehicle's technical specifications.
3Loss of information
If driver assistance systems require communication infrastructure between vehicles, then the system can exchange detailed collision data, but the system becomes inapplicable to vehicles without such infrastructure
Solution Approach 1:
The patent extracts the essential collision warning information from complex vehicle-to-vehicle communication protocols and presents it in a simplified format that does not require communication infrastructure. The system takes out only the critical data elements needed for warning (collision imminence, direction, severity) and transmits them through basic sensory channels that any driver can perceive, eliminating the need for sophisticated communication hardware in the third-party vehicle.

Function Achieved in This Case
This approach enhances accident safety by directly warning third-party vehicle drivers of potential collisions, even if their vehicle lacks a driver assistance system, preventing accidents without the need for vehicle-to-vehicle communication.

AI summary
A method for warning a vehicle driver of a third party vehicle, in particular of a motor vehicle, of a collision, the vehicle driver of the driving third party vehicle being warned by the host vehicle of an imminent collision with a correspondingly front host vehicle, and the vehicle driver of the tailgating third party vehicle is signaled the imminent collision with the host vehicle by a driver assistance system of the host vehicle. Also described is a computer program product, an arithmetic unit, or a processing device, which may be a control device or a control unit for a vehicle, as well as to a driver assistance system for a vehicle, in particular a motor vehicle.
