摘要： PROBLEM TO BE SOLVED: To control torque of an engine with high accuracy by calculating torque of an internal combustion engine by a model as a function of an operation variable, deciding a value to maximum torque from a prescribed characteristic curve group, and correcting the maximum torque by deciding efficiency to a controlled variable of the internal combustion engine. SOLUTION: A characteristic curve group 100 for maximum illustrated high pressure torque is used to determine the maximum illustrated high pressure torque Miopt as a function of an engine speed Nmot and relative air filling quantity r1 by considering a dynamic chracteristic of an intake pipe from an actual air mass flow rate. A deviation from a standard value of the oxygen concentration at that time is determined by a comparing stage 104 to decide efficiency ηλ at that time of the air-fuel ratio according to a characteristic curve 106. The Miopt is desirably corrected at a joining point 102 by multiplication by using this efficiency ηλ. A corrected maximum value is corrected by an exhaust gas return rate at that time, a camshaft position, the injection timing, an ignition angle position and corresponding efficiency of an air supply movable valve by correcting stages 108 to 116 to form actual torque Mi.

摘要： PROBLEM TO BE SOLVED: To easily and surely determine a characteristic value by obtaining measurement data to an operation variable of a drive unit for a vehicle by an automatic processing, and optimizing a deviation with respect to the operation variable calculated based on the data and the characteristic value. SOLUTION: Operation of an engine at various operation poins in performed at a test base on table then an effective torque is obtained at each operation point according to a specified program, and a traction torque in noncombustion operation at the same operation point is determined. Thereafter, measurement data is processed according to an optimizing program. Namely, optimization is made by using, as a quality standard, a square sum of a difference between measurement torque (effective torque + traction torque) and a model torque value to each operation point calculated from a known torque model (torque during high pressure process). The optimizing program changes a model parameter by the minimum square method so that the difference may be minimized, and gives it the optimum fitting to the measurement value. Accordingly, a characteristic value is automatically determined in a simple and sure manner.

摘要： PROBLEM TO BE SOLVED: To compensate suitable compatibility for a demand of an internal combustion engine in the case where an ignition angle is decided by calculating additional torque interposing toward the ignition angle found out by a control device, in the case where the ignition angle is calculated. SOLUTION: In a first treatment stage 10 in a control device, after a map ignition angle ZW (KF) is found out on the basis of an operation parameter of an internal combustion engine, it is corrected by a correction rate of an additional ignition angle found out by a knocking control part KR, and a fundamental ignition angle ZW (base) to be obtained is supplied to an input side of a target torque interface 11. A target ignition angle ZW (soll) which is optimized to a torque is fed out to a control stage 12 together with the fundamental ignition angle ZW (base), an output of the control stage 12 is outputted through a control stage 13 so as to prevent the target ignition angle ZW (soll) from exceeding a prescribed ignition angle for securing a knockingless operation.

摘要： PROBLEM TO BE SOLVED: To correct a driver's steering intention to individually and flexibly execute the driver's intention by computing the target hand torque of the driver to be the base of hand torque transmitted to a steering wheel through a steering wheel actuator. SOLUTION: Hand torque is computed through torque measurement, or current measurement of a steering actuator and processed. Hand torque can also be computed from existing vehicle data (v, μ, δv, and the like) through model formation. A: Hand torque is simulated by model support (by a feedback simulator). B: Hand torque is obtained by measurement. Reset torque is computed through measurement of front wheel torque Mv or measurement of steering actuator current Iv and converted. Reset torque reaches a steering column model after adaptive processing and filter processing, so that hand torque of a steering wheel is computed.

摘要： PROBLEM TO BE SOLVED: To optimize a load of a computer by processing at least one of driving quantity and a controlled variable of a performing driving method of a driving sequence by a first time pattern, and processing at least one of driving quantity and a controlled variable of an unperformed driving method by a second time pattern. SOLUTION: When a system is started, first of all, a controller 16 judges, whether or not combustion operation BA1 (for example, stratified charge combustion operation) is performed, and when it is judged as YES, a calculation on driving quantity or target quantity of the combustion operation BA1 is made by a judging or estimating method of a sensor signal. While, when it is judged as NO, whether or not to adjust the same combustion operation BA1 is judged, and when a judgement here is YES, driving quantity or target quantity of the combustion operation BA1 is calculated. While, when it is judged as NO, a similar inquiry and a calculation on combustion operation BA2 (for example, homogeneous combustion operation) is made. The driving quantity is determined by the other combustion operation method at transitional operation time.

摘要： PROBLEM TO BE SOLVED: To use a known charging amount control even for a supercharged internal combustion engine by limiting charging amount to a maximum tolerance. SOLUTION: A basic value (zwbase) on ignition angle, a basic value (λ base) on setting of a mixture, and/or a basic value (redbase) on the number of cutoff cylinders are supplied to a program 36. As a function of other operation variables supplied through these values and a line 22b or 24b, a target value MIsoll derived in a program 34 is converted to a control input for fuel supply amount and an ignition angle, and a target charging amount is derived and converted to a control input for air feeding amount and/or supercharging pressure to an internal combustion engine. A basic ignition angle is determined from a characteristic curve group 38 based on engine speed and charging amount at that time. A characteristic curve group or calculation step with which a basic value for composition of a mixture and/or cutoff of individual cylinder is created is provided.

摘要： PROBLEM TO BE SOLVED: To further optimize a fuel supply amount signal and avoid the formation of leaning and richening which are not intended in the formation of the fuel supply amount signal to be performed by correcting a basic value by various kinds of correction values so as to be compatible to an operation state. SOLUTION: A first signal rl showing air quantity flowing into an internal combustion engine is formed (2.1). Based on the first signal rl, a second signal te λ1 is formed. Thus, when the second signal te λ1 is used as a fuel supply amount signal, a first λ target value is set (2.5 to 2.7). As functions of operation parameters of the internal combustion engine, various kinds of second λ target values are formed (2.9 to 2.12). The second λtarget value having top priority is selected (2.13). By weighting the second signal te λ1 by the second λ target value having top priority, the fuel supply amount signal is formed (2.14).

摘要： PROBLEM TO BE SOLVED: To regulate only a filling rate, and regulate a real moment to a target moment by considering the setting of a mixture composition and the number of a shut-out cylinder, when a target filling value is calculated from a target moment value. SOLUTION: A target moment MIso11 , a rotational speed Nmot , a load r1 are read in S200, and referential values in relation to a referential ignition angle zwbase, a mixture composition and/or the number of shut-out cylinders are decided in S202. Moment correcting values (etazwbase), (etalambase), (etaredbase) in relation to an ignition angle, a mixture composition, and the number of the shut-out cylinders are decided from a prescribed efficiency characteristic curvature in S204, it is judged whether fuel is shut-out or not by coasting operation in S206, a minimum filling rate rlmin is decided from first and second characteristic curvatures f1, f2 in the case of 'YES' or 'NO' in S208, 210, and the product P of a moment correcting value is formed in S212. The quotient of the product P of a target moment and the moment is decided in $214, and the quotient is converted into a filling target value rlsolll by rotational sped and a prescribed characteristic curvature.
