摘要： PURPOSE:To improve speed change control by correcting a prescribed speed change instruction signal only in the case when a throttle is perfectly closed within a prescribed time after the reduction speed of the throttle opening-degree corresponding signal becomes over a judgment value determined according to the operation condition immediately before the start of closing operation. CONSTITUTION:When the throttle opening-degree 303 is reduced according to the step motor-control routine accommodated into the CPU 313 of a speed change controller 300, and the quantity of variation of the turottle opening- degree 303 is larger than a prescribed quantity, and a throttle is perfectly closed within a prescribed time, speed change control is carried-out on the basis of the L-range speed change pattern even if the shift position 304 is in D-range. Therefore, speed change ratio can be favorably controlled, and the operation of engine brake over necessary quantity can be prevented.

摘要： PURPOSE:To reduce a select shock by means of a clutch pressure regulating valve to regulate pressure fed to a clutch, and a solenoid valve to change the regulating action of the clutch pressure regulating valve according to given signal. CONSTITUTION:A clutch pressure regulating valve 116 ordinarily regulates a fixed oil pressure corresponding to the force of a spring 208 through well- known pressure regulating action, but when oil pressure acts from an oil path 189 onto a port 204a, the regulated oil pressure is reduced by the above acting oil pressure. A solenoid valve 118 has a solenoid 224, which is controlled on duty ratio by a speed change controlling unit 300, and discharges oil in an oil path 190 inversely proportional to its passing electric current. In an idling state, regulated pressure produced by the solenoid valve 118 acts on the regulating valve 116 through a switching valve 108 for regulated pressure to slightly couple the clutch, and a select shock can be therefore reduced.

摘要： PURPOSE: To make efficiency in an oil pump improvable so better, by limiting line pressure to only the quantity leaked through a clearance between a clearance in a fitting part between a land at one side and a valve hole, and lessening an oil leakage quantity so exceedingly.
CONSTITUTION: A line pressure regulating valve 102 regulates line pressure in making this line pressure a pressure regulating signal's hydraulic pressure. A part of the line pressure fed to a port 146b is leaked to a port 146c or a drain port through a clearance between an outer diametral part of a plug spool 149 and an inner diametral part of a retainer 147, but this leaked quantity is as negligible as small. That is to say, the leaked spot is confined to this part, and the outer diameter of the plug spool 149 is small enough so that its peripheral length is short, thus oil is hard to leak out. Thus, since the leakage quantity is little, wasteful discharge flow in an oil pump is well reduced so that efficiency is improved.

摘要： PURPOSE:To make a shock reducible in case of shifting a shift lever from a neutral range to a running one, by controlling clutch feed hydraulic pressure with a solenoid valve according to a position a regulated pressure selector valve, while securing the specified creep torque. CONSTITUTION:On the condition that a car speed is low, the specified quantity of energizing to a solenoid 224 takes place with a continuous ration current, and throttle pressure in an oil passage 140 is controlled to be adjusted to the specified value being relatively low. When this relatively low throttle pressure acts on a forward clutch 40 or a backward brake 50, it clamps them together and comes to be a value having the specified creep torque transmitted. Therefore, for example, in case of selecting from a N range to a D range, the throttle pressure set to the relatively low value acts the forward clutch 40 or the backward brake 50 so that a shock in time of selection also comes to be very small.

摘要： PURPOSE: To make a transmission gear ratio controllable in an accurate manner, by controlling the ratio on the basis of the turbine rotational frequency of a hydraulic power transmission system directly related to the rotational frequency of a driving pulley of a stepless transmission mechanism.
CONSTITUTION: A signal out of a turbine rotational frequency sensor accords with rotational frequency of a driving pulley 16 when a forward-backward selector mechanism 15 is in a forward state, while a signal out of a car speed sensor primarily corresponds to rotational frequency of a driven pulley 26. Therefore, a transmission gear ratio calculated on the basis of each signal out of the turbine rotational frequency sensor 301 and the car speed sensor is always congruous with the actual transmission gear ratio so accurately, and on the basis of this, control over the transmission gear ratio is carried out so that such shift control as being excellent in accuracy takes place in case of a stepless transmission which the shift control is regularly carried out.

摘要： PURPOSE: To improve efficiency in a stepless transmission ever so better, by making a minimum value of line pressure accord with the irreducible minimum pressure of a hydraulic power transmission system, while reducing an oil pump loss to the smallest possible extent.
CONSTITUTION: In the line pressure to be obtained by a line pressure regulating valve 102, the larger a transmission gear ratio is, the higher it becomes, the higher the throttle pressure acting on a port 146b is, the higher it becomes. Therefore, the minimum value of the line pressure is 2kg/cm&u2 when the transmission gear ratio is the smallest, and the coupling pressure to be obtained by a coupling pressure regulating valve 120 is always constant in the hydraulic pressure irrespective of the transmission gear ratio and throttle opening, that is to say, it is set to 2kg/cm
2 . Accordingly, the line pressure generally comes to a low characteristic whereby volumetric efficiency in an oil pump is improved.
