Summary:PROBLEM TO BE SOLVED: To provide a device and the like capable of measuring angular velocity and the like about the three-axis of a vehicle with a high degree of accuracy, while attempting for curbing the rise of manufacturing cost of vehicles and for downsizing without using triaxial gyro sensors. SOLUTION: According to a vehicle attitude estimating device 100, based on time varying aspect of an attitude vector psti(k) (i=x, y, z) expressing attitude of a vehicle 1 in the global coordinate system, angular velocity vector ω(k) expressing angular velocity about the three-axis of the vehicle 1 is measured, while attempting for curbing the rise of manufacturing cost of the vehicle 1 and for downsizing without using comparatively expensive triaxial gyro sensors of large in size.
