AI Technical Summary

Technical Problem

In the autonomous driving function, when relying on high-precision maps to regulate the vehicle speed, the data volume is large, the processing resources are consumed, and the map update and maintenance costs are high, and the real-time performance may lead to inconsistent speed limit information and cause safety hazards.

Method used

By obtaining road-level electronic horizon data and visual data in the vehicle's driving direction, the original speed limit value and actual speed limit value of the target speed limit section are obtained, the original speed limit value is corrected based on the actual speed limit value, the target speed limit value is obtained, and the vehicle speed is adjusted before reaching the target speed limit section, so that it is less than or equal to the target speed limit value.

Benefits of technology

It realizes that the vehicle speed is accurately adjusted without relying on high-precision maps, reduces data loading and processing resource consumption, reduces map update and maintenance costs, improves the speed of speed limit information, and ensures the safety of the vehicle.

Abstract

The invention relates to a vehicle speed adjusting method, device and equipment, a medium and a vehicle. The road-level electronic horizon line data of the road in the vehicle driving direction and the visual data of the road in the vehicle driving direction are acquired; acquiring an original speed limit value of the target speed limit road section from the road-level electronic horizon line data, and acquiring an actual speed limit value of the target speed limit road section from the visual data; based on the actual speed limit value, correcting the original speed limit value to obtain a target speed limit value; based on the target speed limit value, before the vehicle arrives at the target speed limit road section, the driving speed of the vehicle is adjusted to be the target speed, the target speed is smaller than or equal to the target speed limit value, the speed of the vehicle can be adjusted according to the road-level electronic horizon line data and the visual data of the road, the road-level electronic horizon line data is easy to obtain, the cost is low, and the data loading amount is small. The cost can be reduced, the updating speed of the speed limiting information is improved, and accurate vehicle speed regulation can be achieved without depending on a high-precision map.
