The invention provides an intelligent driving expected function safety risk assessment method and device. The method comprises the steps of obtaining a first-level function and a second-level function of an intelligent driving system; determining an insufficient function mode of each primary function and each secondary function; determining an insufficient interaction mode among the functions; determining a personnel misuse mode existing in the intelligent driving system; obtaining an intelligent driving system operation design domain; determining a plurality of hazardous events caused by a first-level function deficiency mode, a second-level function deficiency mode, a first-level function interaction deficiency mode, a second-level function interaction deficiency mode and a personnel misuse mode in each scene of the operation design domain; calculating the risk degree of each hazard event in each scene of the operation design domain according to the severity, the occurrence frequency, the detectability and
