Abstract: Aspects of this disclosure relate to controlling one or more vehicle systems based on a determined weather condition. In some embodiments, a radar system can be mounted on a vehicle and can collect weather data by receiving electromagnetic signals. A weather condition can be determined based on the collected weather data, and a vehicle system can be controlled based on the determined weather condition, such as vehicle lighting, windscreen wipers, or cruise control. In some embodiments, weather conditions can include fog, sleet, or smog. The weather condition can be determined by analyzing scattered reflections from incident microwaves and/or radio waves to determine a level of attenuation of the scattered electromagnetic energy indicative of a presence or absence of particles. A map can be displayed displaying the weather condition and controlling vehicle navigation systems. The collected weather data can be compared with data from a LiDAR or camera system for reliability.
