A method and device for tilting a car body of a vehicle in a trackbound train when the train passes through a track curve. The respective vehicles in the train comprise bogies supporting a car body resting thereon, includes devices for tilting the car body in relation to the bogies, for indicating a track curve, and a control system for controlling the tilting of the car body in dependence on the geometry of the track curve. The position of the train along a route is determined point-by-point by the train being equipped with devices for detecting its position and by registering the curve geometry of the track when the train runs over a track section from the determined position, and storing it in real time as a sequence of measured values describing the curve geometry of the track section in an electronic memory. The curve-geometry data about the track section, previously stored in the memory is used for controlling the tilting of the car body during the next passage through curves within the track section.
A method for tilting of a car body of a vehicle in a trackbound train when the train traverses a curved track, the respective vehicle comprising bogies supporting a car body, means for tilting the car body in relation to the bogies, means for indicating a track curve, and a control system for controlling the tilting of the car body in dependence on the geometry of the track curve, the method comprising the steps of:
Means for controlling tilting of at least one car body of a vehicle in a trackbound train when the train transverses a track curve, each respective vehicle in the train comprising bogies and a car body resting thereon, means for tilting the car body in relation to the bogies, means for indicating a track curve, and a control system for controlling the tilting of the car body in dependence on the geometry of the track curve, wherein the train is equipped with means for determining, point-by-point, the position of the train along a route, train borne devices for determining the curve geometry of the track section from a determined position by detecting a sequence of sampled measured values in real time of curve-geometry data for the track section when the train runs over said track section, an electronic memory for storing said sampled sequence of measured values of the curve geometry of the track section, and a second reference-value calculator responsive to at least the latest sequence of the curve-geometry measured values of the track section stored in the memory for calculating a reference value for the tilting of the car body in a vehicle in the train during the next passage of the train, in the same direction, through the curves within the track section.
A method for controlling a car body of a vehicle in a trackbound train passing through a track curve and wherein each respective vehicle in the train comprises bogies supporting a car body thereon, said method comprising the steps of:
