摘要： When a change in an output voltage of a main power supply is a decrease, and a degree of the decrease is larger than a reference value, a power supply control portion decreases a boosted voltage of a voltage-boosting circuit according to the degree of the decrease. When the change in the output voltage of the main power supply is an increase, and a degree of the increase is larger than the reference value, the power supply control portion increases the boosted voltage of the voltage-boosting circuit according to the degree of the increase.

摘要： An actual detected current value and a target voltage value of an electric motor are subjected to a low-pass filter process (S10), and amounts of change dlfx, dVf* per time in the filtered actual current value Ifx and the filtered target voltage value Vf* are calculated (S11). If the amount of change dlfx in the actual current value on the increase side is greater than a criterion value and the amount of change dVf* in the target voltage value on the decrease side is greater than a criterion value (S12, S15), it is judged that the stroke end has been reached. Then, the upper limit value I*lim of the target current value is set at the actual current value Ifxold obtained in the immediately previous cycle of the feedback control (S21), so as to prevent generation of unnecessary torque.
