    摘要: It is an object of the present invention to achieve stabilization of clutch transmission torque at the point of half clutch completion during a garage shift upon vehicle start up, and to thereby achieve smooth clutch engagement. In a vehicle power transmission device in which a fluid coupling and a wet friction clutch are provided in series at points on a power transmission path which extends from an engine to a transmission, and which performs engagement/disengagement control of the clutch by varying the pressure of operating fluid used for engagement/disengagement driving the clutch in accordance with duty pulse signals outputted from an electronic control unit, clutch engagement control is begun at the same time as (t1) the transmission is put into gear in a state of clutch disengagement when a vehicle is about to start up from a standstill. When the difference in rotation between the input and output sides of the fluid coupling reaches or exceeds a predetermined value (t3) during this clutch engagement control, a duty Dc corresponding to full clutch engagement is outputted from the electronic control unit.

    摘要: The present invention aims to enable the accurate learning of a true torque point in a wet friction clutch (3), prevent the clutch connection shock by absorbing the response delay upon an ordinary clutch connection control, and to successfully combine the time lag and shock. In the present invention, the value (D) itself of the duty ratio of the duty pulse output from the ECU (16) is learned as the torque point (Dm). In a power transmission device of a vehicle having a fluid coupling (2) and the wet friction clutch (3)provided in series between the engine (E) and transmission (T/M), the value (Dm) of the duty ratio at the time when the clutch input side revolution (Nt) decreases to a value lower than the engine revolution (Ne) by a prescribed revolution (Nm) during the process of gradually connecting the clutch 3 is learned as the torque point. Preferably, learning is conducted after the elapse of a prescribed waiting time (&Dgr;t1). During an ordinary clutch connection control, a prescribed start duty (Dst0) for connecting the clutch (3) broadly up to a point close to the torque point (Dtb) is initially output from the ECU (16), and a gradual duty (Dk) is output after retaining such start duty (Dst0) for a prescribed time (&Dgr;t3). Preferably, a first gradual duty (Dk1) for gradually connecting the clutch quickly is output, and a second gradual duty (Dk2) for gradually connecting the clutch slowly is output thereafter.

    摘要: The present invention provides a clutch connection method which controls the disconnection/connection of a wet friction clutch on the basis of a duty pulse outputted from an electronic control unit. When the clutch is connected, the electronic control unit initially outputs a start duty (Dst) for largely connecting the clutch as far as the vicinity of a torque point, and, thereafter, outputs, at prescribed time intervals (Δt), a gradual connection duty (Dk) for gradually connecting the clutch, and determines a gradual connection duty value on the basis of a clutch input/output side revolution difference ΔN. Since the clutch is gradually connected while monitoring the clutch connection state, variations between connection times and connection shock, resulting from individual clutch differences or the like, can be eliminated, whereby it is possible to achieve a stable feel. Further, in control which connects the clutch in sync with completion of a transmission gear shift, a plurality of clutch connection modes (an engine plus mode, an in-shaft plus mode, and a synchro mode) are preset, and the clutch connection modes are selected in accordance with the size of clutch input-side and output-side revolution numbers upon completion of a gear shift. Clutch connection is performed which conforms to actual conditions since a clutch connection mode is selected in accordance with the size of clutch input/output side revolution numbers rather than with respect to a shift-up or a shift-down.

    摘要: Construction of a continuously variable transmission device for a vehicle is achieved that, when a shift lever is shifted to a selection position for a direction opposite the traveling direction at that time, it is capable of preventing the vehicle from continuing to travel at high speed in a direction opposite the direction intended by the operator. When the shift lever is shifted to a selection position of a direction opposite the traveling direction at that time, and the vehicle speed is faster than a specified speed (V1), the connection of a clutch device that transmits power between a continuously variable transmission mechanism and a differential gear mechanism is disconnected, and the drive force from the drive source is prevented from being further transmitted to the wheels. As a result, it is possible to cause the vehicle to decelerate without accelerating even when the operator tries to move faster in the opposite direction, or when the operator steps on the accelerator pedal with the intention of accelerating in the opposite direction, and thus it is possible to prevent the vehicle from continuing to travel at high speed in the direction opposite the intended direction of the operator.

    摘要: Construction is achieved that is capable of ensuring reliability of a learned value for a step position of a stepping motor 24 which becomes the criterion for the transmission gear ratio control of a toroidal continuously variable transmission 4 without losing opportunities for learning more than necessary even when the ignition switch is turned OFF during learning of the step position. The controller 11 determines the ON/OFF state of the ignition switch 33, and when it is determined that the ignition switch 33 is in the OFF state, the controller 11 prevents learning control from being executed. The state in which the rpm of the engine 1 is dropping from after the ignition switch 33 is turned OFF is eliminated from being an object of learning control for learning the step position, such that erroneous learning is prevented, while the state in which the rpm of the engine 1 becomes stable after the ignition switch 33 is turned ON is not eliminated.
