    • It is possible to restrain distortions generated in a mixer. A modulator includes a local signal source that generates an in-phase local signal, a multiplier that multiplies an in-phase baseband signal (I) and the in-phase local signal by each other, a phase inverter that receives the in-phase local signal from the local signal source, and inverts the phase thereof, an anti-phase multiplier that multiplies an anti-phase baseband signal (−I) (signal equivalent to a signal obtained by inverting the phase of the in-phase baseband signal (I)) and an output from the phase inverter (anti-phase local signal) by each other, and an adder that adds an output from the multiplier and an output from the anti-phase multiplier to each other. The addition by the adder of a leak component (carrier leak) which is the in-phase local signal leaked from the multiplier, and the signal which is the output from the phase inverter leaked from the anti-phase multiplier to each other results in zero. In other words, the leak component output from the multiplier is cancelled.

    • An oil pressure command value for slip-control of a lock-up clutch of a torque converter is calculated based on a feed-forward oil pressure value calculated by an FF value calculating unit and a feed-back oil pressure value calculated by a feedback value calculating unit. When the feedback oil pressure value is calculated, a deviation out-of-range determining unit determines whether a deviation between actual rotational speed difference and target rotational speed difference is outside of a predetermined range. If the deviation is outside of the predetermined range, a feedback value correcting unit calculates a correction value and corrects the feedback oil pressure value. Therefore, when the deviation is outside of the predetermined range, the actual rotational speed difference is brought into convergence with the target rotational speed difference with rapid response. When the deviation falls within the predetermined range, normal feedback control is adopted to assure stability without overshooting, even in a high engine speed, high engine torque state.
    • 基于由FF值计算单元计算的前馈油压值和由反馈值计算出的反馈油压值,计算用于变矩器的锁止离合器的滑差控制的油压指令值 计算单位。 当计算出反馈油压值时,偏差超出范围确定单元确定实际转速差和目标转速差之间的偏差是否在预定范围之外。 如果偏差超出预定范围,则反馈值校正单元计算校正值并校正反馈油压值。 因此,当偏差超出预定范围时,实际转速差与目标转速差快速响应。 当偏差落在预定范围内时,即使在高发动机转速,高发动机转矩状态下也采用正常反馈控制来确保稳定性而不会过冲。
