Abstract

A shift control device for an electrically driven vehicle, which is installed in the electrically driven vehicle including a motor as a drive source and an automatic transmission coupled to an output shaft of the motor, has a shift controller that performs shifting of the automatic transmission using a previously set shift line. The shift controller has, as the shift line, an electricity consumption prioritized shift line with priority placed to improve electricity consumption rate, and a driving force prioritized shift line with priority placed to suppress the frequency of shifting. The driving force prioritized shift line is used for a predetermined time after completion of the shift control using the electricity consumption prioritized shift line.
