摘要： The invention is directed to a method for determining the actual torque of an internal combustion engine having gasoline direct injection. In the method, the torque of the engine is computed with a model in dependence upon operating variables. A value for the maximum torque, which would be achieved under standard conditions, is specified from a pregiven characteristic field in dependence upon operating variables which characterize an operating point of the engine. An efficiency is inputted for at least one torque-influencing actuating variable of the engine with the efficiency being formed in dependence upon a current or present value of the actuating variable and a standard value of the actuating variable. The maximum torque is corrected with the efficiency to determine the actual torque. The invention is also directed to an arrangement for determining the actual torque of the engine.

摘要： A method and an arrangement for operating internal combustion engines is suggested which is operated in at least one operating state with a lean air/fuel mixture. The fuel mass, which is to be injected, or the injection time, which is to be outputted, is determined in dependence upon a desired value. For monitoring the operability, the actual torque of the engine is determined on the basis of the fuel mass, which is to be injected, or the injection time, which is to be outputted, or the outputted injection time and compared to a maximum permissible torque and a fault reaction is initiated when the actual torque exceeds the maximum permissible torque. Parallel to the above, a quantity, which represents the oxygen concentration in the exhaust gas, is compared to at least one pregiven limit value and a fault reaction is initiated when this quantity exceeds the limit value.

摘要： The method involves determining the driver type by measuring the fuel consumption. A desired value for the fuel consumption is determined on the basis of the actual operation point of the engine and the fuel consumption required to overcome the travelling resistance, comparing it with an average measured actual value and obtaining a measurement for the driver type or a correction for the parameter. An Independent claim is included for a device for implementing the method.

摘要： A method for adjusting the torque in an internal combustion engine is introduced having the steps: determining a desired torque; determining an operating point from measured values for air charge and rpm; determining a standard torque for this operating point; determining a desired efficiency from standard torque and desired torque; determining the lambda corresponding to this efficiency; determining the fuel quantity from the corresponding lambda and the air charge derived from measurement quantities. The fuel quantity in combination with the air charge yields the corresponding lambda for realizing the desired torque.

摘要： Disclosed is a device for determining rotational speed. Rotational speed is determined from the torque measured on the crankshaft of an internal combustion engine. Since torque fluctuates according to the gas force or combustions dependent upon the angle of rotation, rotational speed (n) is calculated according to periods of time (T), whereby the number of cylinders (Z) is taken into account. Evaluation and calculation of signals is normally carried out in the control unit of the internal combustion engine.

摘要： PURPOSE: A method is provided to determine a driver type without requiring any information from another control device. CONSTITUTION: Whether a constant traveling is present or not is inspected(100). In case of the constant traveling, whether a mark 'constant traveling' is set or not is inspected(102). When no mark is set, the actual range of a traveling resistance characteristic curve to a selected gear step is determined on the basis of actual rotating speed nA and actual torque MdA(104). The target value to absolute fuel consumption is determined(106). The actual value to the absolute fuel consumption is determined(110), and averaged with time or a prescribed traveling distance to provide an average actual value(112). The target value is compared with the average actual value(114), and a parameter(for example, pedal characteristic curve) regulates the gear stage so as to be sportier when the actual value is larger than the target value and to be more comfortable in the reverse case.
