The first decoupling mechanism (11) is closed to couple the torque transmitting means (8) to the torque generating machine (4) and is opened to decouple the torque transmitting means (8) from the torque generating machine (4). A second decoupling mechanism (12) is operable to decouple the torque transmitting means (8) from the one or more driven wheel. The second decoupling mechanism (12) is closed to couple the torque transmitting means (8) to the one or more driven wheel and is opened to decouple the torque transmitting means (8) from the one or more driven wheel.

A vehicle control device comprising: a balance gradient calculation unit configured to calculate a balance gradient that is a gradient at which a propulsive force of the vehicle and a resistance force applied to the vehicle are balanced when the vehicle travels in a gear-in coasting state in which an engine is connected to a gear and the vehicle travels without supplying fuel to the engine, in a case where a traveling state of the vehicle is a neutral coasting state; and a traveling control unit configured to: switch, based on the calculated balance gradient and a specified road gradient, the traveling state of the vehicle from the neutral coasting state to the gear-in coasting state in a case where the traveling state of the vehicle is the neutral coasting state; and end, the gear-in coasting state when determining that an end condition is satisfied.

An automatic travel control unit (120) of this travel control device (100) makes a vehicle travel according to a travel schedule including driven travel and inertial travel. When an accelerator opening degree output from an accelerator sensor (31) exceeds a first threshold value, an inertial travel control unit (110) prohibits inertial travel, and when the accelerator opening degree is smaller than a second threshold value that is less than the first threshold value, the automatic travel control unit (120) performs a control operation so as to cancel the prohibition of inertial travel.

A method of controlling engine restart may include selecting, by a start controller, a first start situation and a second start situation for restarting an engine; determining a current possible start-up through the first and second start situations; prioritizing possible start-ups; and attempting to restart the engine by setting the first and second start situations as first start control and second start control, respectively, based on the priorities of the start-ups.
