TL;DR: In this paper, a hydraulic suspension system with a plurality of actuators having working fluid chambers is presented, where cut-off valves and pressure control devices are provided in the supply passages and the discharge passages.
Patent
Fluid pressure type active suspension responsive to change of rate of change of vehicle height or change of acceleration of vehicle body
Takashi Yonekawa,Shuuichi Buma,Toshio Aburaya,Kunihito Sato,Masaki Kawanishi,Kouichi Kokubo,Takami Sugiyama,Toshiaki Hamada +7 more
TL;DR: In this article, a fluid pressure type active suspension in a vehicle such as an automobile is described, where an actuator supporting a vehicle body from a wheel is operated by a pressure control means which controls the fluid pressure supplied in the fluid chamber of the actuator according to certain control parameters including at least a rate of change of vehicle height or an acceleration of the vehicle body.
Patent
Apparatus for estimating vehicle speed based on detected wheel speed, without influence of noise included in the detected wheel speed
TL;DR: In this paper, a vehicle speed detecting device was proposed, where the speeds of vehicle wheels are detected by wheel speed detecting devices, and the vehicle running speed is estimated by a speed estimating device, on the basis of the detected wheel speeds, and according to a predetermined estimation rule.
Patent
Fluid pressure type active suspension with bypass control for working fluid pressure operative with variable target value
Takashi Yonekawa,Shuuichi Buma,Toshio Aburaya,Kunihito Sato,Masaki Kawanishi,Kouichi Kokubo,Yutaka Iguchi +6 more
TL;DR: In this paper, a fluid pressure type active suspension in a vehicle such as an automobile is described, where the vehicle body is supported by an actuator supporting a vehicle body from a wheel so as to be able to vary a height relative to the wheel in accordance with the fluid pressure supplied to its fluid chamber.
