Automatic driving method and device

Abstract

The embodiment of the invention discloses an automatic driving method and device. The device comprises an automatic driving module and a monitoring module used for monitoring the automatic driving module. The automatic driving module comprises a positioning sub-module used for positioning a vehicle; an environment sensing sub-module used for sensing the environment where the vehicle is located; a path planning sub-module used for performing path planning according to a positioning result and an environment sensing result; and a motion control sub-module used for performing motion control on the vehicle according to a path planning result. The monitoring module is used for controlling the vehicle to enter a minimum risk state when at least one of a positioning result, an environment sensing result, a path planning result and a motion control result is monitored to be abnormal. According to the embodiment of the invention, positioning, environment perception, path planning and motion control are all monitored, so that the safety of automatic driving can be improved, and the requirement of high-level automatic driving for safety is met.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to an automatic driving method and device. Background technique [0002] Automated driving (also called: automated driving, or driving automation) means that a vehicle continuously performs some or all dynamic driving tasks in an automatic manner. With the increasing electronicization of vehicles and the development of technologies such as artificial intelligence, automatic driving has also evolved from assisted driving to more advanced and intelligent fully automatic driving. For example, in some application scenarios, it has been able to achieve completely unmanned Driving, that is, the automatic driving system completely takes over the control of the vehicle, without the need for a driver in the vehicle. [0003] For the level of automatic driving of automobiles, there are detailed classifications in "Automated Driving Classification of Automobiles" (GB / T 40429...

Problems solved by technology

However, the inventors of the present application have found in practice that for high-level automatic driving, the existing technology only monitors a relatively important single part, which may not be sufficient to ensure the safety requirements of automatic driving, especially for High-level automatic driving, so there is a need for further improvement of existing technologies
