A characteristic selection/current upper limit value calculation section 64 selects a cranking upper limit characteristic map MP2 in the case where a cranking state is detected by a cranking state supposition section 63, and selects a non-cranking upper limit characteristic map MP1 in the case where the cranking state is not detected. Upper limit limitation on a current caused to pass through a motor 20 is relaxed in a cranking upper limit characteristic as compared with a non-cranking upper limit characteristic. Consequently, it is possible to prevent excessive current limitation during cranking.
