In-Vehicle Display Overlaying Hazard Warning Indicia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle display systems lack effective methods to alert drivers to potential hazards such as vehicles in blind spots, fast approaching vehicles, and tailgating situations, which can lead to accidents due to inadequate information about surrounding objects.
Innovation Solution
A computer-implemented method and system that overlays warning indicia on an in-vehicle display by determining the position, speed, and time of detected vehicles using proximity sensors or dedicated short-range communication, alerting the driver with visual and auditory signals when a potential hazard is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional mirrors are used for rear and side views, then the device structure is simple, but the driver lacks information about potential hazards such as vehicles in blind spots and fast approaching vehicles
Solution Approach 1:
The patent combines multiple functions into a single in-vehicle display system: traditional rear/side view display, hazard detection, and warning indication are merged into one integrated display that shows camera images overlaid with hazard information from proximity sensors and DSRC data
Solution Approach 2:
The in-vehicle display serves multiple purposes: it displays standard rear and side views for general monitoring, simultaneously detects potential hazards using sensor data, and provides specific warnings for identified threats, making the system universally applicable for both routine monitoring and hazard alerting
2Reliability
If no hazard detection system is implemented, then the device complexity is low, but the driver safety is compromised due to inadequate information about surrounding objects
Solution Approach 1:
The patent uses intermediary systems to bridge the gap between raw sensor data and driver awareness: proximity sensors and DSRC receivers gather data, the processing system analyzes this data to identify hazards, and the display system presents processed hazard information to the driver, creating an intermediary layer that enhances safety without requiring direct driver interaction with raw sensor data
Solution Approach 2:
The system performs preliminary hazard detection and classification before presenting information to the driver, using proximity sensors and DSRC data to identify potential threats in advance, allowing the driver to take preventive action before hazards become critical situations
3Measurement precision
If comprehensive hazard detection is implemented using multiple sensors, then the measurement precision of hazard identification is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The patent segments the hazard detection function across multiple independent sensors (proximity sensors for close objects, DSRC receivers for communication with other vehicles), each sensor handling specific detection tasks, allowing the system to achieve comprehensive coverage while maintaining modular complexity that can be managed independently

AI summary
Examples of techniques for overlaying on an in-vehicle display road objects associated with potential hazards are disclosed. In one example implementation, a method may include: responsive to detecting a presence of a detected vehicle in proximity to the local vehicle, determining, by a processing device, a position of the detected vehicle, a speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; determining, by the processing device, whether the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle based on the position of the detected vehicle, the speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; and responsive to determining that the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle, overlaying, by the processing device, a warning indicium on the in-vehicle display.
