    • A control device for a variable valve timing apparatus that changes valve timing of at least one of an intake valve and an exhaust valve of an internal combustion engine includes an actual valve timing computing unit and a valve timing controlling unit. The actual valve timing computing unit computes actual valve timing. The valve timing controlling unit controls the variable valve timing apparatus to maintain present valve timing during starting of the internal combustion engine before the actual valve timing computing unit becomes capable of computing the actual valve timing. The valve timing controlling unit controls the variable valve timing apparatus such that the actual valve timing becomes target valve timing during the starting of the internal combustion engine after the actual valve timing computing unit becomes capable of computing the actual valve timing.
    • 用于改变内燃机的进气门和排气门中的至少一个的气门正时的可变气门正时装置的控制装置包括实际气门正时计算单元和气门正时控制单元。 实际气门正时计算单元计算实际气门正时。 气门正时控制单元控制可变气门正时装置,以在实际气门正时计算单元能够计算实际气门正时之前维持内燃机启动期间的当前气门正时。 气门正时控制单元控制可变气门正时装置,使得在实际气门正时计算单元能够计算实际气门正时之后,实际气门正时成为内燃机起动期间的目标气门正时。

    • A required valve timing change rate Vreq is calculated so as to make a deviation D between a target valve timing VTtg and an actual valve timing VT small and then a required speed difference DMCRreq between a motor 26 and a camshaft 16 is calculated on a basis of the required valve timing change rate Vreq. When the deviation D is larger than a predetermined value, a required motor speed Rmreq is calculated by adding the required speed difference DMCRreq to a camshaft speed RC and a motor control value is calculated so as to control the motor speed RM to the required motor speed Rmreq. When the deviation D is not larger than the predetermined value, the camshaft speed RC is set as the required motor speed Rmreq and the motor control value is calculated so as to control the motor speed RM to the camshaft speed RC.
    • 计算所需的气门正时变化率Vreq,以使目标气门正时VTtg与实际气门正时VT之间的偏差D小,然后根据电动机26与凸轮轴16之间的所需速度差DMCRreq计算 所需气门正时变化率Vreq。 当偏差D大于预定值时,通过将所需的速度差DMCRreq与凸轮轴速度RC相加来计算所需的电动机速度Rmreq,并且计算电动机控制值,以便将电动机速度RM控制为所需的电动机速度 Rmreq。 当偏差D不大于预定值时,凸轮轴速度RC被设定为所需的电动机速度Rmreq,并且计算电动机控制值,以将电动机速度RM控制到凸轮轴速度RC。
