    Abstract: Provided is a vehicle regenerative speed control device for suppressing undershooting, in which the actual transmission input rotational speed falls below a lower-limit rotational speed, when decreasing the transmission input rotational speed based on a request for a decrease in the regeneration amount during regenerative speed control.
    The present invention has a belt-type continuously variable transmission (6), a motor generator (4), and a main oil pump (14). The FF hybrid vehicle has a hybrid control module (81) which, when there is a request for an increase in the regeneration amount while decelerating, performs a regenerative speed control for downshifting the belt-type continuously variable transmission (6) to the low gear ratio side, and increasing rotational speed of a transmission input shaft to which the motor generator (4) is connected. The hybrid control module (81) also performs a control for making the rotational speed decrease change rate of the Pri end command rotational speed lower than the rotational speed increase change rate of the Pri end command rotational speed, when the Pri end command rotational speed is being decreased based on a request for a decrease in the regeneration amount during regenerative speed control.
