AI Technical Summary

Technical Problem

The existing high-speed navigation autonomous driving technology relies on high-precision maps and positioning, which is susceptible to map update frequency, is costly, and in places where high-precision positioning is inaccurate, lane change control of autonomous driving cannot be achieved.

Method used

The vehicle-mounted camera is used to collect image data, and the vehicle is currently located through the autonomous driving domain controller, and lane path switching control is performed based on the destination information of the navigation map to realize lane change control.

Benefits of technology

Without relying on high-precision maps, it is possible to control and locate the vehicle's roads, reducing cost expenditures and improving the reliability and applicability of autonomous driving.

Abstract

The invention discloses a path control system and method in high-speed navigation automatic driving. The path control system comprises a vehicle-mounted camera, an automatic driving domain controller and a cabin controller, the vehicle-mounted camera is used for collecting image data around a vehicle, and the output end of the vehicle-mounted camera is connected to the automatic driving domain controller; the automatic driving domain controller identifies the current lane position of the vehicle based on the image data; the automatic driving domain controller controls lane path switching control of the vehicle according to destination information of a navigation map of the cabin controller and a current lane position. The method has the advantages that the vehicle changing road line can be controlled and positioned without depending on a high-precision map during high-speed navigation automatic control, and the cost expenditure is reduced.
