Meteorological condition prediction method and device for self-driving vehicle, vehicle and controller

Abstract

The invention relates to a meteorological condition prediction method and device for a self-driving vehicle, a vehicle and a controller, and aims to solve the problem that in the prior art, the real meteorological environment of the environment where the vehicle is located cannot be predicted, so that safety threats exist in vehicle driving. The method comprises the steps of determining a third initial rainfall level based on windscreen wiper information, determining a light level based on lamplight information, and determining an illumination level based on visibility information and information of an environment scene where a vehicle is located; determining a final rainfall level based on the first initial rainfall level, the second initial rainfall level and the third initial rainfall level; determining a final illumination level based on the illumination level, the light level, the pollution level information and the weather type information; determining whether the environment temperature exceeds the standard or not based on the environment temperature information; and according to the result, determining whether the meteorological condition of the current environment of the vehicle meets automatic driving or not.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a weather condition prediction method, device, vehicle and controller for an automatic driving vehicle. Background technique [0002] The monitoring of meteorological conditions is one of the important conditions for the design and operation of automatic driving. The monitoring of meteorological conditions includes dimensions such as visibility, precipitation, high temperature on the road surface, wind force, low temperature freezing, snowfall, sandstorms, and light. The monitoring accuracy of meteorological conditions is to ensure that the automatic driving The prerequisite for driving a vehicle safely is to ensure that the autonomous vehicle operates within a safe range. The monitoring of current meteorological conditions generally uses sensors, such as cameras, rainfall and sunlight sensors, and temperature sensors. However, due to the limitations of sensor functions and perfo...
