Overtaking Assistance Using Lateral Distance Alerts for Cyclists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in accurately maintaining a safe distance and speed when overtaking vehicles such as bicycles, leading to potential accidents and violations of traffic laws, as existing systems lack precise judgment and adaptive assistance.
Innovation Solution
A system and method that utilizes an image-capturing unit, ECU, and wireless communication to detect vehicles ahead, providing alerts via HUD or AR-HUD to ensure safe overtaking by determining safe distance and speed thresholds, and communicating with other vehicles through DSRC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver makes an approximate guess to maintain safe distance, then the operation is simple, but the accuracy of distance judgment is insufficient leading to potential accidents
Solution Approach 1:
The patent replaces the driver's manual distance judgment (mechanical/visual estimation) with an electronic control unit that automatically calculates lateral distance using sensor data from image-capturing units and vehicle communication systems. This substitution provides precise measurement without requiring complex manual assessment procedures.
Solution Approach 2:
The electronic control unit acts as an intermediary between the image-capturing units/sensors and the driver, processing raw sensor data and converting it into actionable safety alerts. This intermediary layer handles the complexity of distance calculation algorithms and presents simplified information to the driver through alert signals.
2Productivity
If the driver overtakes at high speed, then the productivity is improved, but the safety of the overtaken vehicle rider deteriorates causing intimidation and potential accidents
Solution Approach 1:
The system continuously monitors the lateral distance between the motor vehicle and the overtaken vehicle (bicycle) and provides real-time feedback to the driver through safety alerts. This feedback mechanism allows the driver to adjust overtaking speed and positioning to maintain safe distances, balancing overtaking efficiency with rider safety.
Solution Approach 2:
The electronic control unit calculates predicted lateral distance at the time of overtaking before the actual overtaking maneuver is completed. By providing advance warning signals when the predicted distance falls below safe thresholds, the system enables the driver to take preliminary corrective actions (adjust speed or position) to prevent unsafe overtaking conditions.
3Reliability
If the driver relies on approximate guessing, then the ease of operation is maintained, but the reliability of safe distance maintenance deteriorates leading to violations and accidents
Solution Approach 1:
The electronic control unit performs self-service by automatically acquiring sensor data from image-capturing units and vehicle communication systems, calculating lateral distances using embedded algorithms, and generating safety alerts without requiring manual intervention from the driver. This automation maintains operational simplicity while significantly improving the reliability of safe distance maintenance.

AI summary
Various aspects of a system and method to provide driving assistance to safely overtake a vehicle are disclosed herein. In accordance with an embodiment, an electronic control unit used in a first vehicle is configured to detect a second vehicle in front of the first vehicle. A first position associated with the first vehicle and a second position associated with the detected second vehicle is determined for a first time instance. It may be determined whether a lateral distance between the determined first position and the determined second position is below a pre-defined threshold distance. A first alert is generated when the determined lateral distance is below the pre-defined threshold distance.
