A controller determines a target rotation speed of an engine from an operation amount of an accelerator operating member. The controller determines whether a vehicle is in coasting deceleration. The controller decreases a differential pressure between a first circuit and a second circuit of a hydraulic circuit according to a deviation between an actual rotation speed of the engine and the target rotation speed, or the operation amount of the accelerator operating member when the vehicle is in the coasting deceleration.

Provided is a method for changing gear ratio in a gearbox comprising: receiving a signal to change the gear ratio; calculating braking torque that the engine should provide to reduce the rotational speed of the engine to a target rotational speed; phase-shifting a second camshaft in relation to the crankshaft, to a state where the exhaust valve is controlled to be opened during the expansion stroke and closed during the exhaust stroke; disconnecting the engine from the driving wheel; opening and closing the exhaust valve with a decompression device in a transition area between an exhaust stroke and an inlet stroke and also between a compression stroke and an expansion stroke, when the piston is at a top dead center in the cylinder to achieve engine braking through compression in the cylinders during the exhaust stroke and the compression stroke, and f) shifting a gear in the gearbox.

A shift lever is configured to take deceleration-requesting positions through its operation in a specified direction from an M-range position for a manual mode. A control is configured such that vehicle's deceleration is larger when an operational quantity of a one-time operation of the shift lever operated toward the deceleration-requesting positions B1, B2, B3 is larger. For example, when the shift lever is operated to the position B1, one-stage shift down is performed, when the shift lever is operated to the position B2, two-stage shift down is performed, and when the shift lever is operated to the position B3, three-stage shift down is performed.
