Abstract
An ECU increases an engine rotation speed when the ECU determines that an inclination angle of an uphill is larger than or equal to a predetermined value, an accelerator is off and a vehicle speed in a direction opposite to a travelling direction of a vehicle, indicated by a specified range, is increasing. Subsequently, the ECU acquires an engine stall predicted vehicle speed, and calculates a predetermined value used in an immediate engine stall determination condition from a current rate of increase per unit time of a turbine rotation speed. Then, the ECU determines that immediate engine stall determination is affirmative when a rotation speed difference between the engine rotation speed and the turbine rotation speed becomes smaller than the predetermined value, and executes engine stall prevention control.
