The invention relates to an intelligent automobile grading early warning system based on driver risk perception reliability. Comprising a driver risk area judgment module based on eye movement information, an objective environment anisotropy risk field calculation module, an objective environment anisotropy risk field view conversion module and an intelligent automobile risk area judgment module based on driver intention. A human-vehicle risk perception result representation module based on a risk perception cumulative effect and a decline effect; a driver risk perception reliability quantification module; and a grading early warning module based on driver risk perception reliability. According to the invention, through the construction of an anisotropic driving risk field, the division of a driving visual field area, the capture of visual focus points of a driver, space-time convolution operation and the like, longitudinal and lateral combined early warning is realized from the risk perception level of the driver; the problems of inaccurate traffic environment risk description, difficulty in quantitative description and evaluation of driver risk perception conditions, longitudinal and lateral early warning splitting, early warning lagging and the like are effectively solved, and the performance of an early warning system is improved.
