Problems solved by technology

Therefore, if the above-mentioned speed change allowable rotational speed is set according to the technology of the above-mentioned Patent Document 1, the time from the stop of the engine to the stop of the transmission belt wound on the drive side pulley is very short, so there is a problem that it is difficult to return the speed change ratio to the low ratio side. question

Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a side view showing an embodiment of a scooter-type hybrid vehicle to which the present invention is applied.

[0035] The hybrid vehicle has a front fork 1 pivotally supporting a front wheel WF at the front of the vehicle body, the front fork 1 is pivotally supported by a head pipe 2 and can be manipulated by an operating handle 3 . A down tube 4 is attached rearward and downward from the head tube 2 , and an intermediate frame 5 extends substantially horizontally from the lower end of the down tube 4 . In addition, a rear frame 6 is formed from the rear end of the middle frame 5 toward the rear and upward.

[0036] On the vehicle frame 10 constructed in this way, one end of a power unit 11 is pivotally connected, and the power unit 11 includes an engine as a power source and a driving motor. At the other end behind the power unit 11 ...

Abstract

The invention provides a variable speed control device of a variable speed case, which can lead the variation ratio to stably return to a low ratio side even in a hybrid vehicle that an engine is stopped when in deceleration. The variable speed control device comprises a control unit (7); wherein, according to detecting signals from a variation ratio sensor (38) and a belt pulley revolution transmitter at a driving side (37), a control chart logged in a controlling chart registration part (7c) ensures the starting running speed of a belt pulley at the driving side after being returned and thedutyfactor of an actuator, and a control instruction is sent to the actuator (77) which changes the variation ratio through changing the groove width of the belt pulley at the driving side. The control instruction is set to be sent after an engine stopping instruction from a driving control part, the closer to a high ratio side the variation ratio is drew, the higher the starting running speed ofthe actuator is. Based on the control, the variation ratio is closer to the high ratio side, and the rotary speed change rate of the belt pulley at the driving side is higher, thus a big dutyfactor isprovided until the rotation of the belt pulley at the driving side stops, to lead the variation ratio to return to the low ratio side.

Description

technical field [0001] The present invention relates to a speed change control device of a continuously variable transmission, and in particular to a hybrid vehicle in which the engine is stopped during deceleration or the like, capable of stably returning the gear ratio of the continuously variable transmission to the low ratio side during deceleration or the like The variable speed control device of the continuously variable transmission. Background technique [0002] In a transmission mechanism that transmits driving force of an engine to drive wheels through a belt-type continuously variable transmission, there is known a vehicle having an actuator that changes a gear ratio by changing a groove width of a driving side pulley. In the normal running state of the above vehicle, the groove width of the drive side pulley is narrower on the high ratio side than on the low ratio side. In the vehicle in which the centrifugal starting clutch is provided on the input side (drive ...
