PROBLEM TO BE SOLVED: To solve the problem of a conventional shift control device for an electric vehicle in which, engagement clutch connection request is transmitted after the rotational frequencies on an input side and an output side of an engagement clutch are synchronized; however, as an operation speed of the engagement clutch is not regulated, time until the completion of engagement can become long, and quick response to an acceleration request from a driver cannot be achieved.SOLUTION: A shift control device for an electric vehicle includes: a drive motor MG2 for generating a driving torque transmitted to a driving wheel; and an accelerator opening sensor for detecting an accelerator opening. Also, the shift control device includes a transmission 3 which has a low speed stage in which an engagement clutch 3b is provided for transmitting the driving torque when an input side and an output side are engaged and a high speed stage, and which is provided between the drive motor and the driving wheel 10. Furthermore, the shift control device includes clutch control means, and the clutch control means engages the engagement clutch after the rotational frequencies on the input side and the output side of the engagement clutch are synchronized. In the case of engaging the engagement clutch, the larger the accelerator opening is, the larger the operation speed of the engagement clutch becomes.SELECTED DRAWING: Figure 1 |
