Intervehicle Sensor Sharing for Beyond-Range Hazard Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems lack the ability to facilitate direct communication between vehicles, limiting the sharing of sensor data and notifications beyond immediate proximity, and do not provide comprehensive awareness of objects or events outside the vehicle's sensory range.
Innovation Solution
A system and method for intervehicle communication that enables the sharing of sensor data, driver actions, and notifications between vehicles using wireless communication links, including graphical, haptic, and audio interfaces to display information from other vehicles and static objects, allowing for enhanced situational awareness and interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor equipment is used to detect objects, then collision detection capability is improved, but detection range is limited to immediate proximity
Solution Approach 1:
The patent uses wireless communication signals as an intermediary to extend detection range. Instead of relying solely on direct sensor detection, the system receives sensor data from other vehicles via wireless communication, allowing a vehicle to detect objects beyond its own sensor range by using other vehicles as intermediaries.
Solution Approach 2:
The patent merges sensor data from multiple vehicles to create a comprehensive situational awareness picture. By combining detection data from various sources (own sensors + received sensor data from other vehicles), the system achieves both precise collision detection and extended detection range.
2Loss of information
If communication equipment is added to vehicles, then information sharing between vehicles is enabled, but direct vehicle-to-vehicle communication capability is lacking
Solution Approach 1:
The patent implements a universal communication system that handles multiple types of information exchange (sensor data, collision notifications, parking space information) through a single wireless communication interface. This multi-functional approach enables comprehensive information sharing while maintaining system simplicity and adaptability.
3Loss of information
If sensor data from other vehicles is received, then situational awareness beyond sensory range is achieved, but system complexity increases
Solution Approach 1:
The patent segments the information processing system into distinct functional modules: wireless communication interface for receiving data, processing unit for analyzing sensor data, and notification system for alerting drivers. This segmentation manages complexity by organizing functions into separate, manageable components while achieving comprehensive situational awareness.

AI summary
Technologies are shown for intervehicle communication involving notification messages sent from one vehicle to another vehicle. Sensor event data from one vehicle can be sent in a wireless message to another vehicle and information from the wireless message displayed to a driver of the other vehicle providing the driver with information that may not be detectable by the sensors in the driver's vehicle. The information from the wireless message can be displayed to the user on a user interface and can include a representation of an object detected by the other vehicle along with information about the position, speed, type or direction of the detected object. User interfaces can include graphical user interfaces, haptic devices and audio devices.
