Abstract
A vehicle body inclination controller includes an air spring, an air reservoir, valve devices, an acquisition section, and a determination section. The determination section compares, with a predetermined threshold, at least one of a value of a ratio between supply control information of a supply valve and exhaust control information of an exhaust valve in the same valve device among the valve devices, a value of a ratio between pieces of the supply control information of the supply valves of different valve devices among the valve devices, or a value of a ratio between pieces of the exhaust control information of the exhaust valves of different valve devices among the valve devices, and determines that a failure occurs in the same valve device or at least one of the different valve devices when the value of the ratio exceeds the predetermined threshold.
