Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detection range of radar-sensing equipment in autonomous vehicles is insufficient due to limitations in spectrum and power, leading to inadequate detection capabilities.
Innovation Solution
A radar-sensing detection method and apparatus based on radar-sensing communication integration, where the position of a receiving end is determined using radar-sensing or communication signals, and beam control signals are sent to optimize data transmission, allowing for the fusion of detection results from both the sending and receiving ends to enhance detection range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If radar-sensing equipment uses higher power and spectrum to extend detection distance, then detection range is improved, but energy consumption and device complexity increase
Solution Approach 1:
The patent combines radar-sensing equipment and communication equipment into an integrated system where the communication equipment's transmitted signals are reused for sensing purposes. This merging allows the system to achieve extended detection range without proportionally increasing energy consumption, as the same transmission serves dual functions.
Solution Approach 2:
The communication equipment is designed to serve multiple functions: both communication and sensing. By making the sensing system universal (capable of both communicating and detecting), the patent avoids the need for separate dedicated sensing transmitters, thereby reducing overall energy consumption while maintaining extended detection capability.
2Length of stationary object
If radar-sensing equipment uses higher power and spectrum to extend detection distance, then detection range is improved, but device complexity increases
Solution Approach 1:
The patent merges radar-sensing equipment and communication equipment into a single integrated system. This combination reduces device complexity by eliminating redundant components and simplifying the overall system architecture, while still achieving extended detection range through the coordinated use of both equipment types.
Solution Approach 2:
The integrated system is designed with multi-functionality, where the same hardware components perform both communication and sensing tasks. This universality reduces device complexity by avoiding the need for separate dedicated systems, while maintaining the capability for extended detection range.
3Length of stationary object
If radar-sensing equipment operates independently with limited detection range, then device complexity is reduced, but detection range is insufficient
Solution Approach 1:
The patent introduces communication equipment as an intermediary that bridges the gap between independently operating radar systems. The communication equipment relays detection information between vehicles, effectively extending the detection range of each individual radar system without requiring each radar to independently achieve long-range detection, thus managing system complexity.
Solution Approach 2:
The patent combines independently operating radar-sensing equipment with communication equipment into an integrated system. This merging allows each vehicle to maintain relatively simple individual radar systems while achieving collective extended detection range through the coordinated networked operation of multiple vehicles.
4Loss of information
If detection information from multiple sources is stored separately, then data completeness is improved, but data storage requirements increase
Solution Approach 1:
The patent merges detection information from multiple sources (own radar and other vehicles' radar via communication) into a unified detection result. This consolidation reduces data storage requirements by eliminating redundant information while maintaining detection information completeness, as the fused result contains the essential detection data without duplicating raw sensor inputs.
Solution Approach 2:
Instead of storing complete raw detection data from multiple sources, the system uses communication to transmit compressed or summarized detection information (effectively a copy or representation of the full data). This approach maintains detection information completeness while significantly reducing the storage volume required, as only essential detection results need to be stored rather than all raw sensor data.

Function Achieved in This Case
This approach enables autonomous vehicles to detect vehicles within a broader range by integrating radar-sensing and communication systems, overcoming the limitations of individual radar-sensing equipment and reducing data storage needs by fusing detection information.
Implementation Method 1
The radar-sensing equipment sends electromagnetic wave to irradiate the target and receives its echo, so as to obtain information such as a distance between the target and the electromagnetic wave sending point, change rate of distance (radial velocity), azimuth, altitude and other information
