Abstract

The authors are developing a "Next-Generation Tilt Control System" aimed at mitigating motion sickness specific to tilting vehicles. To suppress low-frequency lateral acceleration, identified as a primary cause of motion sickness, precise control of the tilt angle in response to track curvature is essential. A method for generating target tilt angles has already been proposed to achieve this goal. The authors introduce a control algorithm for a pneumatic actuator that can follow these continuous target values. This algorithm combines displacement feedback control of the actuator with velocity and acceleration feedback, as well as feedforward control. The effectiveness of the proposed control algorithm is demonstrated through bench tests and running tests. Furthermore, the results in the “Next-Generation Tilt Control System” show an improvement in ride comfort compared to the ones in the conventional system.
