Abstract

A damper device comprising a first mode having a first level of damping, a second mode having a second level of damping corresponding to a predetermined function, a sensor system having a first output corresponding to a normal position and a second output corresponding to an end stop approaching position, and a control system operable for receiving the first output and the second output and executing the first mode and the second mode. The damper device is operable in the first mode when the control system receives the first output and is operable in the second mode when the control system receives the second output. A controllable suspension system comprising a damper device, a magnetic probe, a sensor system comprising at least one position sensor operable for sensing the position of the magnetic probe, and a control system electronically connected to the sensor system and the damper device, wherein the control system is operable for receiving an output from the sensor system and executing a predetermined function to control the damper device. Electric signals are supplied to the damper device from the control system during system operation to provide damping sufficient to preven…
