摘要： PROBLEM TO BE SOLVED: To provide a variable valve timing device capable of reducing electric power consumption by valve timing control when stopping an engine. SOLUTION: A convergence determination of intake valve phase control is performed by a comparison between a phase deviation ¾ΔIV(θ)¾ and a convergence determining value θj of an intake valve to a target phase (S140). In convergence (when determining as YES of S140), a determination is made that an intake valve phase reaches the target phase, and since a phase variation in a required camshaft is set to zero, an actuator operation quantity is also set to zero (S160). Thus, when stopping the engine when the target phase is a fixed value, after convergence of the intake valve phase control, operation of an actuator is stopped. When further stopping the engine, the convergence determining value is set by switching when stopping the engine and when operating the engine so that the convergence determination of the intake valve phase control becomes gentler than when operating the engine (S120 and S130).

摘要翻译：要解决的问题：提供一种可变气门正时装置，其能够在停止发动机时通过气门正时控制来降低电力消耗。解决方案：通过相位偏差¾ΔIV（θ）¾与进气门到目标相位的会聚判定值θj（S140）之间的比较来进行进气门相位控制的收敛判定。收敛时（当S140为“是”时），判断为进气门相达到目标相位，并且由于所需凸轮轴的相位变化为零，所以致动器运转量也为零（S160 ）。因此，当目标相位为固定值时停止发动机时，在进气门相位控制收敛后，停止执行器的动作。当进一步停止发动机时，通过在停止发动机时和在操作发动机时切换来设定收敛确定值，使得进气门相位控制的收敛确定比操作发动机时变得更温和（S120和S130）。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a variable valve timing system using an electric motor as an actuator, capable of appropriately detecting the overheated state of the electric motor and a drive unit so as to protect the system and improve the controlling performance. SOLUTION: An actuator operation quantity setting portion 6000 generates a rotational speed command value Nmref for the electric motor 2060 so that the phase of an intake valve is changed to match a target phase. An electric-motor EDU 4100 controls electric power PWm supplied to the electric motor so that the electric motor 2060 operates in accordance with the rotational speed command value Nmref. An overheat judgment portion 6200 judges whether it is necessary to restrict heat generation or not based on comparison between information showing the electric power PWm supplied to the motor and a criterion of judgment DTYj. A command value restricting portion 6300 restricts the rotational speed command value Nmref fed to the electric-motor EDU 4100 within a predetermined range when it is judged that the restriction of heat generation is required. A judgment criterion setting portion 6100 sets the judgment criterion DTYj to be variable according to the rotational speed of the electric motor 2060. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an air-conditioner for a vehicle capable of collecting the energy at deceleration sufficiently. SOLUTION: An air-conditioning control device for this air-conditioner for the vehicle corrects the target cooling temperature TEO of an evaporator to γ°C lower than the value before deceleration when the vehicle is in deceleration (Step S140), and controls a compressor to the maximum displacement irrespective of the target cooling temperature TEOS in case the sensed temperature TE of an evaporator blowout temperature sensor is equal to or above the corrected target cooling temperature TEOS (Step S170). Since the displacement of the compressor does not increase gradually, but attains the maximum displacement quickly, it is possible to collect the deceleration energy sufficiently and perform cold accumulation to the maximum limit.

摘要： PROBLEM TO BE SOLVED: To provide an air-conditioner for a vehicle capable of exerting a still higher fuel-saving effect while the cooling feeling of the occupant is secured. SOLUTION: The air-conditioner for the vehicle accumulates the cold in an evaporator upon correcting the target cooling temperature TEO of the evaporator to γ°C lower than the value before deceleration when the vehicle is in deceleration (Step S130), and when the vehicle has stopped, sets the higher corrected target temperature TEOK obtained by correcting the target cooling temperature TEC to some higher value and stops the compressor until the sensed temperature TE of an evaporator blowout temperature sensor exceeds TEOK (Step S180). Thereby the calorific value cold accumulated in the evaporator 6 at deceleration can be utilized effectively while the cooling feeling of the occupant is secured during the stop.

摘要： PROBLEM TO BE SOLVED: To enhance the stability of a valve timing control by properly setting a control signal for operational instruction to an actuator. SOLUTION: An ECU 4000 provides pulse wave-like operation instruction signals SGI for indicating the operational instruction of an electric motor 2060 as a VVT actuator to an electric motor EDU 4100. The electric motor EDU 4100 recognizes the operating direction of the actuator and the combination of control modes by the duty ratio of the operation instruction signals SGI and also recognizes a rotational speed instruction value from the frequency of the operation instruction signals SGI, and drivingly controls the electric motor 2060 according to the operational instruction. The duty ratio by each of the combinations of the operation instruction signals SGI is so determined that, even if the duty ratio is erroneously recognized, the erroneous recognition in the operating direction of the actuator that the changing direction of a valve phase is reverse to an intended one is prevented from occurring, and even if the erroneous recognition occurs, the phase change rate at that time can be suppressed.

摘要： PROBLEM TO BE SOLVED: To prevent instability of rotation of an internal combustion engine when changing in an auxiliary machine load generating state in idle speed control.
SOLUTION: When an auxiliary machine load is changed to a generation state from a non-generation state on the basis of a signal of an air conditioner switch in idling ([YES] in S152, and [YES] in S154), both throttle opening, a working angle of an intake valve and a lift quantity are increased by an adjusting quantity resistible to the generated auxiliary machine load (S158). Thus, a suction air quantity supplied to a combustion chamber can be quickly increased, and instability is not caused by reduction in an engine speed.
