A guardrail estimation method based on multi-sensor data fusion is provided. The guardrail estimation method comprises acquiring multi-sensor data and vehicle information, determining a traveling track of the vehicle based on the vehicle information, determining multiple guardrail sample points based on the multi-sensor data and the traveling track, and estimating guardrail information based on the multiple guardrail sample points. When the vehicle is controlled laterally, the guardrail information is used for correcting a lane line of poor quality; and when the lane line cannot be detected, the guardrail information is used for a lateral control downgrade processing, and the guardrail information also facilitates aided realization of fast and accurate expressway lane-level localization and realization of a higher-level aided driving function.
