Patent number: 4821188Abstract: In this vehicle height adjustment system, a plurality of actuator assemblies are provided, one corresponding to each one of the vehicle wheels and resiliently suspending it from the vehicle body. These actuator assemblies have pressure chambers, and each is adapted to increase or decrease the vehicle height at a location corresponding to its corresponding wheel as respective results of supplying or discharging of working fluid to or from its pressure chamber. Working fluid supply/discharge means are provided corresponding to the actuator assemblies and supply and discharge working fluid to and from their pressure chambers. Vehicle height detection means are provided for sensing the heights of the vehicle above the wheels. A means detects the rate of change of the steering angle of the vehicle.Type: GrantFiled: October 22, 1986Date of Patent: April 11, 1989Assignees: Toyota Jidosha Kabushiki Kaisha, Toyota Central Research and Development Laboratories, Inc.Inventors: Hiroyuki Ikemoto, Nobutaka Oowa, Yasuji Arai, Osamu Yasuike, Shunichi Doi

Patent number: 4809176Abstract: In this system for vehicle roll control, a plurality of duty radio controlled actuator assemblies are provided, one corresponding to each one of the vehicle wheels, and resiliently suspended from the vehicle body. These actuator assemblies have pressure chambers, and each is adapted to increase or decrease the vehicle height at a location corresponding to its corresponding vehicle wheel as a result of the supplying or discharging of working fluid to or from its pressure chamber. Working fluid supplying and discharging means supply working fluid to and discharge working fluid from the pressure chambers of the actuator assemblies. The system further includes means for sensing the road speed of the vehicle, and means for sensing the steering angle of the vehicle. Vehicle height detection means are also provided for sensing the heights of the vehicle above the vehicle wheels.Type: GrantFiled: October 22, 1986Date of Patent: February 28, 1989Assignees: Toyota Jidosha Kabushiki Kaisha, Toyota Central Research and Development Laboratories, Inc.Inventors: Nobutaka Oowa, Yasuji Arai, Osamu Yasuike, Hiroyuki Ikemoto, Shunichi Doi

Patent number: 4797823Abstract: In this roll control system, suspension means are provided for resiliently suspending the vehicle wheels with variable hardness/softness characteristics, each suspension means including an actuator with a pressure chamber which increases or decreases wheel suspension height according to the supply or discharge of working fluid. Working fluid supply/discharge means are provided for the actuators, to supply and discharge working fluid to and from actuator pressure chambers. The road speed, the steering angle, and the actual body roll angle are detected. Means for computing and control computes a steady state vehicle body roll angle .phi..sub..infin. from the vehicle speed and steering angle, advances the phase of a signal indicative of .phi..sub..infin. to compute a compensating roll angle value .PHI..sub..infin., and then computes a difference value .phi. based upon a desired roll angle .phi..sub.a, .PHI..sub..infin., and the actual roll angle .phi..sub.t, according to the equation:.phi.=.phi..sub.a -(k1.PHI..Type: GrantFiled: October 21, 1986Date of Patent: January 10, 1989Assignees: Toyota Jidosha Kabushiki Kaisha, Toyota Central Research & Development Laboratories, Inc.Inventors: Hiroyuki Ikemoto, Nobutaka Oowa, Yasutaka Hayashi, Shunichi Doi
