A current increase-decrease amount (”I ³ * ) computed by a command current increase-decrease amount computing unit (61) is added to an immediately preceding value (I ³ * (n-1)) of a command current value (I ³ * ) in an adder (62). The command current value (I ³ * ) obtained by the adder (62) is given to a high/low limit limiter (63). The high/low limit limiter (63) limits the command current value (I ³ * ), obtained by the adder (62), to a value between a low limit value (¾ min (¾ min ‰¥ 0)) and a high limit value (¾ max (¾ max > ¾ min )). A high limit value setting unit (64) obtains the high limit value (¾ max ) corresponding to the vehicle speed detected by the vehicle speed sensor (6), from a vehicle speed-vs.-high limit value map set by a map creating/updating unit (39), and sets the obtained high limit value (¾ max ) in the high/low limit limiter (63). |
