The invention provides a vehicle perception performance evaluation method and system, and the method comprises the steps: carrying out the qualitative analysis of a perception system of a vehicle, so as to obtain a performance index representing the capability of the perception system, and environment factors related to the performance index; establishing a mathematical model between the performance indexes of the sensing system and the environmental factors through quantitative analysis; detecting whether the precision of the mathematical model meets a preset requirement or not; if not, obtaining the mathematical model again; and if yes, evaluating the sensing system according to the mathematical model. By means of the mode, the mathematical model between the capacity of the vehicle sensing system and the external environment factors can be established, and the mathematical model can evaluate the capacity of the sensing system in real time in the operation process of the sensing system.
