Title: Select shock reducing device in automatic speed reduction gear
Inventor: NIIKURA YASUHIRO
IPC: F16H61/04
Filed: 1985-04-23
Abstract: PURPOSE:To reduce select shock, by carrying out a feed-back control of the operating hydraulic pressure of a starting frictional element in such a way that upon change-over into a running range the hydraulic pressure is increased at a desired rate which is required to prevent select shock. CONSTITUTION:Outputs from a hydraulic pressure detecting means (g) for detecting the hydraulic pressure of a starting frictional element (d) and a pressure increasing rate setting means (h) for setting a desired rate of pressure increase required to prevent select shock of hydraulic pressure, are delivered to a pressure regulating means (i) to carry out the feed-back control of hydraulic pressure. With this arrangement, the hydraulic pressure may be always raised at a desired rate without being affected by manufacturing errors of an automatic speed reduction gear (e), the temperature of hydraulic oil and variations in the drive voltage of the pressure regulating means, thereby it is possible to reduce select shock.

Title: Vehicle suspension system
Inventor: TAKAHASHI SATORU
IPC: B60G17/015
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To improve controllability through correction of dispersion in damping force characteristics actually generated by performing variable control of each shock absorber to a damping force characteristic position set by damping force characteristic position set means. SOLUTION: In the vehicle suspension system, a three-dimensional correction map is obtained by an experiment preliminarily using a relation among a control signal, a sprung-unsprung relative speed Vp, and damping force characteristics generated at each damping force characteristic position. Each shock absorber is controlled to a damping force characteristic position corrected by the three- dimensional map to correct dispersion thereof, thus, improving controllability. Using the three-dimensional map for correcting the dispersion makes it possible to easily obtain a predetermined correction function. Also, control accuracy is improved using the spring-unsprung relative speed Vp signal at a low frequency that contains spring resonance frequency so as to be processed through band pass filter(BPF).
