Multitrack curve-tilting vehicle, and method for tilting a vehicle
First Claim
1. Multitrack curve-tilting vehicle having at least three supporting elements for at least the purposes of transmitting a lateral guiding force between the vehicle and a ground, whereinat least two of the at least three supporting elements are laterally disposed on opposite sides of the vehicle'"'"'s longitudinal axis andat least one of the at least three supporting elements can be steered for directional control of the vehicle,withmeans for laterally tilting at least one section of the vehicle about a tilting axis running essentially parallel to the vehicle'"'"'s longitudinal axis, so that while driving, the center of gravity of the vehicle can be displaced in a direction perpendicular to the direction of travel, andat least one vehicle seat disposed on the tiltable section of the vehicle, for a driver steering the vehicle,characterized in thatmeans of detection are provided for capturing a lateral sitting force exerted by the driver'"'"'s body onto at least one vehicle-seat portion of the vehicle seat in a lateral direction perpendicular to the direction of travel,the means of detection are in operative connection with the means for lateral tilting, in such a way thatthe lateral tilting occurs as a function of the detected lateral sitting force andthe tilting speed is a function, at least of the lateral sitting force and the speed of the vehicle, the tilting speed increasing with increasing lateral sitting force, with a factor that decreases with increasing vehicle speed.

Abstract
A curve-tilting vehicle, e.g., a three-wheeled vehicle (30), including a laterally tilting device (4) at least one section (5) of the vehicle by a tilting axis (6) that runs substantially parallel to the longitudinal axis (3) of the vehicle such that the center of gravity of the vehicle can be displaced perpendicular to the direction of travel when driving, especially in curves or on a sloped or uneven ground. The vehicle includes at least one vehicle seat (8a) that is disposed in the tilting section (5) of the vehicle and is allocated to the driver who steers the vehicle. The vehicle further includes a detector (9a) for detecting a lateral force of the seat, which the body of the driver applies at least to one zone of the vehicle seat (8a) in a lateral direction (10a) extending perpendicular to the direction of travel. The lateral force of the seat may be detected using a pivotal spring-centered vehicle seat (8a). The detector (9a) is effectively connected to the lateral tilting includes (4) in such a way that lateral tilting occurs in accordance with the detected lateral force of the seat while the tilting speed is a function at least of the lateral force of the seat and the vehicle speed, the tilting speed increasing as the lateral force of the seat rises at a factor that decreases as the speed of the vehicle goes up. The invention further relates to a method for tilting such a vehicle.
