How Weather Affects Self-Driving Cars

Weather conditions have a significant impact on the performance of self-driving cars and their sensors. The ability of LiDAR, radar, and cameras to accurately perceive the environment can be influenced by adverse weather conditions. For instance, heavy fog can severely limit visibility, making it challenging for cameras to detect objects. LiDAR sensors may struggle to differentiate between weather occurrences and solid obstacles, leading to false positives and negatives. On the other hand, radar technology remains relatively unaffected by weather conditions, providing more reliable data even in challenging environments.

In extreme weather situations, self-driving cars rely on a combination of sensors to gather data and inform navigation decisions. While cameras may struggle in low visibility conditions, the collaboration between LiDAR, radar, and cameras allows the software to make informed decisions based on the available information.

Self-driving car companies continuously strive to improve sensor performance and develop advanced algorithms to enhance the vehicles’ ability to navigate safely in various weather conditions.
