Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic driving vehicles, the existing technologies face challenges in accurately determining the sensing range of Road Side Units (RSUs) in real-time due to varying installation locations and environments, leading to reduced communication efficiency and safety.
Innovation Solution
A method and apparatus that actively measure the sensing range by determining the target RSU based on its identifier, calculating vehicle positioning information when receiving a road-side message, and defining the sensing range using the first and last receiving positions within a target lane, which can include dividing the lane into sub-sections based on intersections or RSU locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a preset fixed communication range is used for RSU, then the system complexity is reduced, but the measurement precision of sensing range deteriorates
Solution Approach 1:
The patent implements dynamic sensing range measurement by continuously tracking the vehicle's position when receiving road-side messages and calculating the actual communication range based on real-time positioning data, transforming the static preset range into a dynamic measured value that adapts to environmental changes
Solution Approach 2:
The patent replaces the mechanical/predefined communication range setting with an electronic measurement system that uses vehicle positioning information and message reception detection to automatically calculate and determine the actual sensing range
2Ease of operation
If passive reception of road-side messages is used, then the ease of operation is improved, but the reliability of automatic driving deteriorates
Solution Approach 1:
The patent introduces feedback mechanisms by detecting message reception status and using vehicle positioning information to continuously measure and update the sensing range, providing real-time feedback about the actual communication environment to improve driving reliability
Solution Approach 2:
The system performs self-measurement of its own sensing range by utilizing its message reception capability and positioning system, automatically determining the communication range without external intervention while maintaining operational simplicity
3Loss of time
If sensing range measurement is not performed in real-time, then the loss of time is reduced, but the adaptability to environment changes deteriorates
Solution Approach 1:
The patent implements periodic sensing range measurement by continuously detecting message reception and updating position information at regular intervals during vehicle operation, ensuring the system adapts to environmental changes without excessive time consumption

AI summary
The present disclosure provides a method for measuring a sensing range of a vehicle, an apparatus, a device and a medium. The method includes: determining a target road side unit to be measured according to a road side unit identifier; when it is detected that the vehicle receives a road-side message from the target road side unit, determining vehicle positioning information when the road-side message is received; and determining a sensing range of the vehicle to the target road side unit in a lane in which the vehicle travels according to the vehicle positioning information. Therefore, a traditional way of passively receiving road-side messages is changed into actively sensing the action range to avoid neglecting sensing range changing with time, which provides a basis for reliable operation of automatic driving vehicles on specific road sections, thereby improving the safety of the automatic driving vehicles.
