To provide a driver load measuring method, device, and program, and a stora ge medium for storing the program which can accurately measure a load on a driv er driving a vehicle accompanied by attitude changes. The driver load measuring device includes a yaw rate detecting section for detecting a yaw rate y as a n example of the angular velocity of a vehicle accompanied by attitude changes , a storing section for storing the results of detection of the yaw rate y, a predicting section for predicting an n-th yaw rate according to an actual [n-1]-th yaw rate y[n-1], an actual [n-2]-th yaw rate y[n-2], and an actual [n-3]-th yaw rate y[n-3] each detected previously, an error calculating section for calculating an error a between a predicted result yp[n] of the n-th yaw rate and an actual n-th yaw rate y[n], a frequency distribution recording section for recording a frequency distribution of the errors a in a predetermined time period, a cell setting section for obtaining a % tile value a according to the above frequency distribution and setting a plurality of ranges (cells) discrete from this % tile value a at a predetermined rate, an error classifying section for classifying all the errors a into the plural cells, and a calculating section for calculating a yaw rate entro py Hp according to the resultsof classification of the errors e.
