AI Technical Summary

Problems solved by technology

However, compared with traditional maps, high-definition maps contain a lot of additional information, so their data volume is also very large
Therefore, sending high-precision map information of all lanes at the same time requires a large system bandwidth, and the requirements for receiving, storing and processing capabilities of the lane change control system are also high, which restricts the effective realization of automatic driving.

Abstract

The invention relates to a high-precision map processing method and device for automatic driving lane change. In one embodiment, the high-precision map processing device for automatic driving lane change includes: a determination unit configured to determine the road change position according to the navigation route and the current vehicle position; Multiple lane change units are required, each lane change unit corresponds to at least one lane change, and each lane change unit has a corresponding variable lane range; and the sending unit is configured to, when driving to a certain lane change unit Before the starting position of the lane change range, if the lane change unit is not the last one among the multiple lane change units, send the high-precision map information of the target lane of the lane change unit to the lane change control system.

Description

technical field [0001] The present invention generally relates to automatic driving technology, and more specifically relates to a high-precision map processing method and device for automatic driving lane change. Background technique [0002] Autonomous driving technology can reduce people's burden of driving vehicles, improve traffic safety and improve traffic efficiency, so it is a research and development hotspot in recent years. Generally, according to the degree of automation, automatic driving technology can be divided into L0-L4 levels, where L0 level means no automation, that is, there is no automatic driving function, and all functions of the vehicle are completely controlled by the driver; L1 level Indicates driving support, that is, to provide basic technical assistance to the driver, such as adaptive cruise control system, etc.; L2 level indicates partial automation, which realizes automatic control of various functions, such as automatic cruise control, lane ke...
