Abstract

The present application provides a method and device for determining an automatic driving strategy, which relates to the field of artificial intelligence and is used to make the automatic driving system adjust the driving strategy of the automatic driving vehicle according to the type of road surface. The method includes: the determining device acquires the current vehicle speed and M spectral characteristic curves of the vehicle, and determines the road surface type of the road section to be driven by the vehicle according to the M spectral characteristic curves and all sample curves in the standard sample curve library. Afterwards, the determining device determines the automatic driving strategy according to the current vehicle speed of the vehicle and the road surface type of the road section on which the vehicle is to travel. This application is applied in the process of vehicle automatic driving.

Description

technical field [0001] The present application relates to the field of artificial intelligence, in particular to a method and device for determining an automatic driving strategy. Background technique [0002] Autonomous vehicles, also known as unmanned vehicles, are intelligent vehicles that realize driverless driving through an automatic driving system. The autonomous driving system uses artificial intelligence, visual computing, radar, and global positioning system to enable smart cars to drive automatically and safely without the active operation of the user. [0003] The current automatic driving system mostly uses millimeter-wave radar to perform 3D modeling of things around the vehicle (such as obstacles appearing in front). After that, the automatic driving system adjusts the driving strategy (such as deceleration and avoidance) according to the geometric characteristics of the obstacle (such as the distance between the obstacle and the car, the size of the obstacle...
