PROBLEM TO BE SOLVED: To effectively determine whether an abnormality occurs or not concerning a motion control device of a vehicle including a control unit on which various actuators for the motion control of the vehicle are loaded. SOLUTION: This abnormality determination device is applied to the motion control device on which a vehicle behavior sensor (yaw rate sensor, etc.) is integrally arranged on an integrated unit constituted by integrating an HU (hydraulic unit) and an ECU. A pattern of vibrating noise existing in output (yaw rate sensor output Yrfilpc, etc.) of the vehicle behavior sensor is provided in the case of actuating the various actuators such as a motor, a solenoid valve, etc. loaded on the HU for primary check of the HU by the previously decided pattern on this abnormality determination device. It is determined in accordance with the abnormal form of the pattern of vibrating noise that abnormality of the vehicle behavior sensor, or working abnormality of the actuators in the HU, etc. occurs when the pattern of this vibrating noise is not within a region of a previously decided normal pattern.
