摘要： PROBLEM TO BE SOLVED: To improve realizing accuracy in a torque request attainable by the suction air volume, in a control device of an internal combustion engine capable of controlling torque of the internal combustion engine by the suction air volume and the ignition timing. SOLUTION: A torque summarizing part 2 and a torque arbitrating part 4 set target torque required by the internal combustion engine by selecting any one of a torque request (future torque) to be realized by the suction air volume and a torque request (just near torque) to be realized by the ignition timing. An intake system control part 10 calculates the target air volume for attaining the target torque, and controls the suction air volume based on the target air volume. An ignition timing calculating part 30 delays the ignition timing so as to compensate for its torque difference when torque (estimated torque) attained by control of the suction air volume exceeds the target torque. A guard part 6 arranges a guard with the future torque as an upper limit in the target torque input to a target torque correction part 8 when the ignition timing is delayed.

摘要： PROBLEM TO BE SOLVED: To minimize retarding of ignition timing by using control of a valve lift amount while improving responsiveness of engine speed control. SOLUTION: The internal combustion engine 10 is equipped with a valve lift amount calculating part 80 controlling an idle engine speed by changing a lift amount and an operating angle of an air inlet valve 32, and calculation elements 60-76 carrying out torque reserve control. In a target efficiency correction part 84, a retarding amount of the ignition timing is controlled by reducing reserve torque in an area with high responsiveness of torque of a setting area of the valve operating angle. In an area with low responsiveness of torque, the reserve torque is secured as is conventional. By this, in a situation wherein it is all right that the reserve torque is small, additional retarding of the ignition timing for securing excessive reserve torque can be avoided. Accordingly, engine efficiency and fuel economy performance can be improved. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To prevent an unnecessary delay in ignition timing caused by a timelag between estimated torque and required torque. SOLUTION: The ignition timing is set based on torque efficiency as a ratio of the required torque to the estimated torque. A required torque change rate is compared with responsiveness of torque with respect to operation of a throttle, and it is determined whether or not it is possible to achieve the requested torque change rate by the operation of the throttle. When it is possible to achieve the requested torque change rate, the torque efficiency is fixed to the maximum efficiency. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To inhibit generation of shock due to a torque step in fuel cut or recovery from fuel cut. SOLUTION: When fuel cut permission conditions are satisfied, a target torque is gradually reduced to the minimum torque. During that time, a target efficiency is fixed to the maximum. Then, fuel supply is stopped after an output torque of an internal combustion engine drops to the predetermined minimum torque. In recovery form fuel cut, fuel supply is restarted when fuel cut recovery conditions are satisfied, and the target torque is gradually increased from the minimum torque. During that time, the target efficiency is fixed to the maximum. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine preventing a control state of a throttle valve from hunting between full admission control and usual control based on demand torque under the influence of a discretely operated actuator. SOLUTION: Demand torque being maximum torque or more is set as full admission conditions of the throttle valve. When the full admission conditions are established, the valve opening of the throttle valve is controlled to full admission, and when the full admission conditions are not established, the valve opening of the throttle valve is controlled according to the demand torque. The demand torque is set on the basis of maximum torque at the present engine speed. The maximum torque is computed on the assumption that an ACIS (acoustic control induction system) is on if the ACIS is switched from off to on at the higher rotating speed than the present engine speed. If the ACIS is left on or off or switched from on to off, maximum torque is computed assuming the present ACIS state. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供一种内燃机的控制装置，其在离散操作的致动器的影响下，基于需求扭矩，防止节气门的控制状态在完全进入控制和通常控制之间的摆动。
解决方案：将最大扭矩或更大扭矩设定为节流阀的完全进入条件。当完成入场条件建立时，节流阀的阀门开度被控制为完全入场，当完全准入条件不成立时，根据需求扭矩控制节流阀的阀门开度。基于目前发动机转速下的最大转矩设定需求转矩。如果ACIS以比现在的发动机转速更高的转速将ACIS从关闭切换到接通，则假设ACIS（声学控制感应系统）被打开，则计算最大扭矩。如果ACIS打开或关闭或从开启切换到关闭，则假定当前的ACIS状态计算最大扭矩。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a control device for a vehicle, controlling the engine torque of an internal combustion engine driving the vehicle with high accuracy.
SOLUTION: When the internal combustion engine is operated within an operating range outside of a data range serving as the basis of a statistical model, acceleration applied to the vehicle is measured, and a measured value is compared with a reference value equivalent to the case that a target torque is properly output. When the measured value is deviated from the reference value, a relation between an engine parameter and the engine torque is corrected by extrapolation in a direction of reducing deviation.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine, suppressing a remarkable reduction in achievability of a plurality of requirements even if an error is caused between the adjustment result of the plurality of requirements output from a requirement output section and the actual control result. SOLUTION: The plurality of requirements output from the requirement output section is defined within the range of a required value and the distribution of an expected value representing the degree of expectation of each required value within the range of the required value, respectively.
