PROBLEM TO BE SOLVED: To accurately detect wheel alignment status of a vehicle. SOLUTION: Front and back force F<SB>x</SB>and side force F<SB>y</SB>working on each tire are detected with tire force sensors 12. When the vehicle is running straight without drive force and braking force working to the vehicle, an alignment status judgment part 41b judges whether the synthetic force of the front and back force F<SB>x</SB>and the side force F<SB>y</SB>detected with the tire force sensor has a direction and magnitude of judging range. When the direction or the magnitude of the synthetic force of each tire is not within the judging range as the results of the judgment, anomaly is reported from an alarm output part 14.
