PROBLEM TO BE SOLVED: To eliminate a racing run feeling and deceleration feeling in a coast condition of a vehicle, also improve a response at the time of re-acceleration, in a driving gear for the vehicle provided with an automatic transmission. SOLUTION: A driving gear for a vehicle has a drive source comprising an engine 1 and/or motor generator 4 and an automatic transmission 3 speed changing power thereof transmitted to a wheel. In a control device 5 of the driving gear, a coast condition of the vehicle is judged in a coast judge means, by a rotational speed control means controlling a rotational speed of the drive source, so that an input rotational speed of the automatic transmission 3 is a target rotational speed eliminating the coast condition, a rotational speed is controlled. |
