Abstract

To secure the drivability of an electric vehicle mounted with a mechanical automatic transmission.SOLUTION: A control device 1 of a vehicle 10 mounted with a mechanical automatic transmission 5 and a brake 7 comprises a prediction unit 1A and a control unit 1B. The prediction unit 1A predicts vehicle speeds Va, Vb at a time point at which the shift-down of the mechanical automatic transmission 5 is complete in a case where the vehicle 10 is decelerating on an uphill road and an accelerator opening degree AP is equal to or greater than a predetermined value Xo. The control unit 1B executes shift-down when the vehicle speed Va predicted by the prediction unit 1A before execution of the shift-down is equal to or less than a first threshold Xa, and operates the brake 7 when the vehicle speed Vb predicted by the prediction unit 1A during execution of the shift-down is equal to or less than a second threshold Xb smaller than the first threshold Xa.SELECTED DRAWING: Figure 1
