Method for operating a tilting running gear and an active tilting running gear for a non-rail-borne vehicle
First Claim
1. A method of operating a tilting running gear for a non-rail-borne vehicle having at least one actuator, comprising:
- calculating, via a controller, an angle of tilt of the vehicle around an axis of rotation based on measured values of centrifugal acceleration and gravitational acceleration as the vehicle enters a curve;
accelerating or decelerating a tilt of the vehicle that is provided by the tilting running gear to achieve the calculated angle of tilt, wherein the acceleration or deceleration of the tilt is based at least in part on a comparison between an actual lateral acceleration of the vehicle and a desired lateral acceleration of the vehicle; and
deactivating the actuator via the controller when the calculated angle of tilt has been achieved,wherein the actuator provides acceleration of the tilt and the braking device provides deceleration of the tilt.

Abstract
A method of operating a tilting running gear for a non-rail-borne vehicle having at least one actuator is disclosed. The method includes calculating an angle of tilt of the vehicle around an axis of rotation based on prevailing values of centrifugal acceleration and gravitational acceleration as the vehicle enters a curve. Based on a comparison between an actual lateral acceleration of the vehicle and a desired lateral acceleration of the vehicle, the vehicle is accelerated or decelerated to achieve the calculated angle of tilt. When the calculated angle of tilt has been achieved, the actuator is deactivated. The actuator provides acceleration of the vehicle and a braking device provides deceleration of the vehicle.
