Provided is a driver state assessment device in which, when a driver model identification means (M2) identifies a driver model indicating a input/output relationship of a driver, wherein the input of the driver is a difference between a target azimuth angle and an actual azimuth angle, and the output of the driver is an actual steering angle; a driver model operation amount acquisition means (M3) acquires a driver model steering angle by inputting a current azimuth angle deviation to the driver model; a driver state assessment means (M4) calculates the difference between the current actual steering angle and the driver model steering angle as a residual; and a driver state is assessed on the basis of the residual. Thereby, the residual is a measure representing a fluctuating component, a noise component, a nonlinear component, etc., obtained from the driver model, and thus, the state of the driver, particularly, a low awareness state of the driver, can be precisely assessed, on the basis of the residual. |
