When a traveling drive system is activated at a time t2 in response to a turning of an ignition switch to an ON state at a time t1, a request of P/N (a park lock release inhibit) from an electrically operated motor controller vanishes. Therefore, originally, according to an execution of a park lock release, the vehicle is started in response to a holding of a D position of a shifter. However, in a case where a park lock release inhibit state occurs at a time immediately before a time t2 and the shifter is at the D position at time t2, a present shift inhibit flag takes over the park lock inhibit state at the time immediately before t2 until a time t3 at which the shifter returns to a home (H) position so that the above-described start of the vehicle is prevented. Since, after time t3, the present shift inhibit flag is in a park lock release allowance state, the shifter is operated to the D position at a time t4 and the park lock release is carried out so that the vehicle is travelable. In this way, without addition of another component, the vehicle is, at a low cost, not started even though a re-activation of the traveling drive system, when the shifter is shifted to the position other than the reference position occurs.
