PURPOSE:To prevent lowering of durability to be caused by a failure and an over-load of an actuator by prohibiting the drive of a range switching valve by the actuator at the time of an extreme low temperature or an extreme high temperature. CONSTITUTION:A range control unit 20 for outputting the driving signal to an actuator 34, which drives a range switching valve 34 in response to the range signal output from a range selecting switch 10, cancels the output of the driving signal to the actuator 34 when a temperature detected near the actuator 34 by a temperature detecting unit 52 exists in a range, which is not appropriate for the operation of the actuator 34. |
