Title: Vehicular suspension device
Inventor: KUROKOCHI TAKASHI
IPC: B60G17/015
Filed: 2019-03-04
Abstract: To improve practicality of a vehicular suspension device mounted with a hydraulic damper and an electromagnetic actuator.SOLUTION: A vehicular suspension device: estimates hydraulic pressure P inside a hydraulic damper on the basis of a stroke speed vS which is a relative movement speed between an upper section and a lower section of a spring (S3); and controls actuator force FA in a manner that makes the stroke speed when the estimated hydraulic pressure is equal to or higher than set pressure P0 lower than the stroke speed when the estimated hydraulic pressure is less than the set pressure (S9). Even when a vehicle has a high risk that a significant increase in the hydraulic pressure inside the hydraulic damper causes hydraulic liquid to leak through a sealing section as is the case in traveling on an undulating road, the vehicular suspension device can control the actuator force so as to reduce the stroke speed, thereby curbing the increase in the hydraulic pressure inside the hydraulic damper and preventing the hydraulic liquid from leaking.SELECTED DRAWING: Figure 3
