Abstract

The present invention refers to a method for controlling an electronically adjustable steering damper in a two-wheeled vehicle or motor vehicle, and to an apparatus implementing it, in which the steering damper is able to exert a damping torque on a steering assembly (45) of the two-wheeled vehicle (40) that can be adjusted according to a steering speed (s'). The control method comprises the steps of calculating an instantaneous damping coefficient ( cin(t) ) of the electronically adjustable steering damper based on the at least one controlled variable (s, s') and is characterized in that the at least one controlled variable comprises a yaw rate (s) of the two-wheeled vehicle. Correspondingly, the control apparatus comprises processing means connected to at least one measuring means being suitable for calculating an instantaneous damping coefficient value ( cin(t)) of the steering damper and is characterized in that at least one measuring means comprises a means for measuring a yaw rate ( s) of the two-wheeled vehicle (40) and / or a means for measuring a steering angle (sdelta).

Description

technical field

[0001] The invention relates to a method for controlling an electronically adjustable steering damper in a two-wheeled vehicle or a motor vehicle and a device for implementing the method. Background technique

[0002] Research in the field of motorcycles is increasingly aimed at making vehicles that are more powerful and lighter, and thus have a high degree of natural instability that can be partially mitigated by adapting the steering damper to reduce the modes of vibration it is subjected to restricted.

[0003] Specifically, at low speeds, there are mainly three modes of vibration in a two-wheeled vehicle: the pitch of the vehicle, the hop of the tires, and the wobble mode. The tilt mode is caused by the rotation of the vehicle about a transversal axis through the center of gravity, which causes one suspension to be compressed and the other to be elongated; this mode of vibration usually occurs at low frequencies because of its dynamics ) is controlled b...
