High-precision ADAS map data system based on four-level automatic driving

Abstract

The invention relates to the field of vehicle control, and especially relates to a high-precision ADAS map data system based on four-level automatic driving. The method comprises a manufacturing method, a transmission method and a device. The manufacturing method comprises the following steps: S1, acquiring information: acquiring four-level automatic driving high-precision map data and vehicle positioning information in a private format; S2, extracting information: extracting effective information for generating ADAS map data from the map data in the private format according to the vehicle positioning information; and S3, producing: generating standard ADAS map data according to the extracted information and the topological relation of the forward road network of the vehicle. The transmission method comprises the capability of receiving information from the Ethernet and sending the information to the Ethernet, the capability of receiving and processing the vehicle positioning information and the capability of executing the manufacturing method. The ADAS map data manufacturing method based on the HD Map has the advantages that key elements in a real scene can be restored within an extremely small precision error, so similar safety problems can be smoothly solved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a high-precision ADAS map data system based on four-level automatic driving. Background technique [0002] The advanced driving assistance system is a system that uses sensing, communication, decision-making and execution devices installed on the vehicle to monitor the driver, the vehicle and its driving environment and assist the driver through images, lights, sounds, tactile prompts / warnings or controls. The general term for various systems used by the driver to perform driving tasks or actively avoid / mitigate collision hazards. The high-precision map for intelligent driving is the key infrastructure for automatic driving. It contains rich and accurate lane-level scene semantic information. Map elements usually have centimeter-level precision and can be used for local path planning. The main objects of use are intelligent driving vehicles. The combination of real-time road condi...
