Vehicle Speed Control Using Accident-Risk Area Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle speed control solutions rely on predetermined speed limits prescribed by traffic laws, making it difficult to adjust vehicle speed according to the actual safety situation of the road, thereby failing to effectively improve travel safety.
Innovation Solution
A method where a speed control device identifies accident-prone areas based on historical accident data and sends speed limit commands to vehicles traveling through these areas, reducing their speed below a predetermined limit via a 5G communication network, ensuring speed adjustments are made according to real-time safety conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speed control devices are installed throughout the entire road network, then vehicle travel safety can be continuously monitored and controlled, but infrastructure costs and maintenance requirements increase significantly
Solution Approach 1:
The patent applies local quality by deploying speed control devices only in specific accident-prone areas rather than uniformly across the entire road network. The system identifies high-risk locations based on historical accident data and concentrates monitoring resources where they are most needed, thereby maintaining safety effectiveness while reducing overall infrastructure complexity and costs.
2Device complexity
If speed control devices are deployed only in accident-prone areas, then infrastructure costs are reduced, but the ability to control vehicle speed according to actual safety situations is limited
Solution Approach 1:
The system performs preliminary action by pre-identifying accident-prone areas using historical accident data before deploying speed control devices. This advance preparation allows the system to proactively place monitoring equipment in high-risk locations, ensuring that safety control capabilities are concentrated where they will have the greatest impact while minimizing unnecessary infrastructure deployment.
3Ease of operation
If navigation devices provide speed limit information, then drivers can control vehicle speed, but the speed limits are based on traffic laws rather than actual road safety conditions
Solution Approach 1:
The patent implements feedback by using historical accident data to identify accident-prone areas and dynamically adjusting speed control requirements based on actual road safety conditions rather than static legal speed limits. The system continuously monitors accident patterns and uses this feedback to refine its identification of high-risk areas, ensuring that speed control measures are tailored to actual safety needs and communicated to drivers through navigation devices.

AI summary
A vehicle speed control method, an apparatus, a device and a storage medium applied to a vehicle. The method includes: receiving (S210) a speed limit command sent by a speed control device, where the speed limit command includes a speed limit, and the speed limit command is generated by the speed control device when it is determined a position of the vehicle is in an area where an accident occurrence rate is greater than or equal to a preset threshold; reducing (S220) a travelling speed of the vehicle to less than the speed limit in response to the speed limit command. According to the vehicle speed control method, vehicle speed can be controlled according to actual safety situation on a road, thereby improving safety of vehicle travelling.
