Abstract: This control device for a vehicle obtain a cant amount CANT by subtracting, from a detected actual lateral acceleration Gy, an estimated lateral acceleration Gyest corresponding to centrifugal force due to a turning run, calculated based upon the difference between the wheel speed at the left side of the vehicle body and the wheel speed at the right side of the vehicle body, by utilizing the fact that a lateral acceleration sensor 54 that detects the detected actual lateral acceleration Gy according to a component of external force (centrifugal force, gravity or the like) exerted on the vehicle detects, as the detected actual lateral acceleration Gy, the acceleration whose absolute value is greater than the absolute value of the actual lateral acceleration (≠0) actually exerted on the vehicle (based upon the centrifugal force due to the turning run), that is running approximately straight, by the amount according to the cant amount CANT in the body roll direction of the road surface.

Abstract: Suction is applied to a pipe of an article. Then, the interior of the pipe is maintained under vacuum conditions for a period of several seconds. This is checked or monitored by a pressure switch. If the pressure in the pipe is raised from the predetermined level, then a pinhole is formed at a welded portion of the pipe to be examined.
