A pure electric autonomous driving system

Abstract

The pure electric automatic driving system provided by the present invention includes: a sequentially connected environmental information collection system, a perception fusion unit, an intelligent decision-making unit, a vehicle motion coordination controller and a vehicle execution system. Among them, the intelligent decision-making unit outputs the local path that the vehicle can travel and the corresponding driving behavior instructions to the vehicle motion coordination controller; the vehicle motion coordination controller realizes the lateral motion control and longitudinal motion control of the vehicle, so that the automatic driving system function is divided into modules ization and standardization of information interfaces will help expand the application scenarios of autonomous driving functions and improve the safety experience of autonomous vehicles, such as safe and comfortable autonomous driving at higher speeds and under fault conditions; in addition, due to the vehicle motion coordination controller monitoring The real-time status of the entire autonomous driving system can identify fault conditions in a timely manner and take reasonable countermeasures to ensure the driving safety of autonomous driving under various conditions.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a pure electric automatic driving system. Background technique [0002] As the future development direction of traditional fuel vehicles and new energy vehicles, autonomous driving technology has been vigorously promoted by the industry. Major automakers and high-tech companies around the world have invested a lot of energy in the research and development, testing and verification of autonomous driving related technologies. [0003] Such as figure 1 As shown, it is a schematic structural diagram of an automatic driving system in the prior art. The automatic driving system collects environmental information such as lane lines, traffic lights, and obstacles by setting various sensors, and uses the perception fusion unit to calculate and fuse the environmental information and output the global path. The intelligent decision-making unit is used to calculate and outp...
