Embodiment Construction

[0043] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in the drawings, the same symbols are used for the same or corresponding parts. In addition, the same reference numerals are attached to the same elements in each figure, and overlapping descriptions are omitted.

[0044] First, use figure 1 The configuration of the shift control device 1 of the continuously variable transmission according to the embodiment will be described. figure 1 It is a block diagram showing the configuration of the speed change control device 1 of the continuously variable transmission, and the continuously variable transmission 30 to which the speed change control device 1 of the continuously variable transmission is applied.

[0045] The engine 10 may be in any form, for example, a horizontally opposed 4-cylinder gasoline engine with in-cylinder injection. In the engine 10, the air taken in from th...

Abstract

When a stepped shift control mode has been selected by a selection operation accepting unit and an acquired value of an indicator acquired by an indicator value acquisition module is greater than a required value of the indicator calculated from a required driving force calculated by a drive assist device, a shift control module executes shift control in the stepped shift control mode. If the acquired value is smaller than the required value, the shift control module executes shift control in the stepless shift control mode.

Description

technical field [0001] The present invention relates to a speed change control device for a continuously variable transmission, and more particularly to a speed change control device for a continuously variable transmission that is mounted on a vehicle equipped with a driving support device and that can switch a speed change control mode according to a driver's operation. Background technique [0002] In recent years, a variety of driving modes can be selected (switched) according to the driver's preference, for example, the output characteristics (output mode) of the engine, and the speed change characteristics of the continuously variable transmission, the vehicle of the speed change mode has been put into practical use (for example, refer to Patent Document 1 ). [0003] As such a vehicle, for example, it is possible to respond from three output modes, that is, a standard mode suitable for normal driving, an eco mode (or economy mode) in which the output torque is suppres...
