Pure electric automatic driving system

Abstract

A pure electric automatic driving system provided by the present invention comprises an environmental information acquisition system, a perception fusion unit, an intelligent decision unit, a vehiclemotion coordination controller and a vehicle execution system which are connected orderly, wherein the intelligent decision unit outputs the local paths that a vehicle can drive and the correspondingdriving behavior instructions to the vehicle motion coordination controller, and the vehicle motion coordination controller realizes the transverse motion control and the longitudinal motion control of the vehicle, so that the automatic driving system is modular in function division and normalized in information interfaces, the application scenes of the automatic driving functions are helpful to be expanded, and the riding safety experiences of the automatic driving vehicles, for example, the safe and comfortable automatic driving at a faster vehicle speed and on a faulted working condition, are improved. In addition, the vehicle motion coordination controller monitors the real-time state of the whole automatic driving system, so that the fault states can be identified timely, the reasonable countermeasures can be made, and the driving safety of the automatic driving under various states is guaranteed.

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...
