Meteorological condition prediction method, device, vehicle and controller for automatic driving vehicle

Abstract

The solution relates to a method, device, vehicle and controller for predicting weather conditions of an autonomous vehicle to solve the problem in the prior art that the real weather environment of the vehicle environment cannot be predicted, which leads to safety threats to autonomous driving. The method includes: determining the third initial rainfall level based on wiper information, determining the light level based on light information, determining the light level based on visibility level information and environmental scene information of the vehicle; based on the first initial rainfall level, the second initial rain level and The third initial rainfall level is to determine the final rainfall level; based on the light level, light level, pollution level information and weather type information, the final light level is determined; based on the ambient temperature information, it is determined whether the ambient temperature exceeds the standard; Whether the meteorological conditions of the environment meet the requirements of automatic driving.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a weather condition prediction method, device, automobile 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 autonomous driving. The monitoring of meteorological conditions includes dimensions such as visibility, precipitation, high temperature on the road, wind, low temperature and freezing, snowfall, sandstorms, and illumination. The monitoring accuracy of meteorological conditions is to ensure automatic driving. The prerequisite for safe driving of the vehicle is to ensure that the autonomous vehicle operates within a safe range. The monitoring of current weather conditions generally uses sensors, such as cameras, rainfall and sunlight sensors, and temperature sensors. However, due to the limitations of sensor functions and performance, the...
