摘要： An air fuel ratio control apparatus for an internal combustion engine can achieve control behavior with good stability and response that is appropriate for a delay in an oxygen storage operation of a catalyst, and can always keep the state of purification of the catalyst adequately. The apparatus includes an upstream oxygen sensor (13), a downstream oxygen sensor (15), a first air fuel ratio feedback control section (130) that adjusts an amount of fuel to be supplied so as to make an air fuel ratio in an upstream exhaust gas and an upstream target air fuel ratio (AFobj) coincide with each other, and a second air fuel ratio feedback control section (150) that operates the upstream target air fuel ratio (AFobj) in accordance with an air fuel ratio deviation between an air fuel ratio detected by the downstream oxygen sensor (15) and a downstream target air fuel ratio so as to make the detected air fuel ratio of said downstream oxygen sensor (15) and the downstream target air fuel ratio coincide with each other. The second air fuel ratio feedback control section (150) sets an integral gain of integral calculation to be larger in accordance with an increasing flow rate of the exhaust gas, and also sets a proportional gain of proportional calculation so as not to be changed with respect to a change in the flow rate of the exhaust gas.

摘要： A control system which is capable of avoiding an overloaded state of an actuator without using sensors or the like. An ECU 2 of the control system 1 calculates a lift control input U_Liftin to a variable valve lift mechanism 50 with an algorithm expressed by equations (2) to (5), such that the valve lift Liftin follows up a target valve lift Liftin_cmd, calculates a cumulative value Simot by cumulative calculation of the product of the value Imot of electric current flowing through the variable valve lift mechanism 50 and a sampling time period Stime, and when SImot≧Simot_J1 holds, sets two parameters pole_f_lf and ploe_lf to respective predetermined failure-time parameters pole_f_lf_J1 and ploe_lf_J1 which cause the lift control input U_Liftin to become smaller than when Simot

摘要： A driving amount controller is provided for a vehicle. An ECU on the vehicle reduces a damping output Udamp when the deviation e between the target opening DTHR of the throttle valve and the actual opening DTH is near zero or when a switching function value σ is near zero. This makes it possible to reduce the damping output Udamp immediately after the start of, or immediately before the end of, the control of the opening of the throttle valve when the deviation e or the switching function value σ is near zero, and to realize a high response performance as to the control of the actual opening DTH of the throttle valve.

摘要： In a method of controlling an exhaust gas turbocharger of an internal combustion engine charged by a compressor wherein as guide value for the control an operating point of the compressor is used, the operation of each cylinder bank of the internal combustion engine is controlled by dividing the total air mass flow by the number of cylinder banks and an equal amount of desired air mass flow is assigned to each cylinder bank and if the air mass flow to any of the cylinder banks is smaller than that to the other or others air from the other cylinder bank or banks is supplied to the one cylinder bank via a compensation arrangement so that the air mass flows to all cylinder banks are essentially equal.

摘要： A closed-loop control for a cam phase adjustment mechanism includes gain terms that are adaptively adjusted to optimize the rate of response of the control to changes in the desired cam phase. The rate of response of the cam phase adjustment mechanism is sampled under specified operating conditions or during certain repeated engine events that involve a change in the desired cam phase, and the deviation of the measured rate of response from the nominal rate of response is determined and used to adjust the closed-loop control gains for restoring the nominal response.

摘要： One embodiment includes an internal combustion engine, a sensor signal representative of an observed engine speed, and a controller. This controller is responsive to the sensor signal to determine a control input representative of a difference between the observed engine speed and a desired engine speed. The controller defines a compensator that is one or more of a proportional-integral type, a proportional-derivative type, and a proportional-integral-derivative type. The controller determines at least one gain factor of the compensator with a signal corresponding to engine load. The compensator is responsive to the control input to generate an output signal to adjust engine fueling as a function of the control input and the gain factor.
