Abstract
A frictional engagement element () that disconnects power between an engine () and a drive wheel () in a vehicle, and a control unit () that controls a transmission ratio of a continuously variable transmission () and the frictional engagement element (), are provided. When the transmission ratio is not a maximum transmission ratio at a vehicle stop when a vehicle speed is 0, the control unit () operates the transmission ratio to the maximum transmission ratio while controlling the frictional engagement element () into a slip state. Further, at this time, when a road is an upward slope, the control unit () sets an engagement pressure of the frictional engagement element () and an engine torque according to the road slope, prevents slide-down of the vehicle.
