    摘要: The method for controlling operation of a vehicle having at least two possible operating modes includes calculating and/or determining the operating variables and/or control variables of at least one active one of at least two possible operating modes in a first continually repeated predetermined time interval and calculating and/or determining the operating variables and/or control variables of at least one inactive one of the at least two possible operating modes in at least one other continually repeated predetermined time interval. The first predetermined time interval is shorter than any of the one or more other predetermined time interval(s). A device for performing the method is also described.

    摘要: A method for operating an internal combustion engine of a motor vehicle with the engine developing a torque during the operation thereof includes deriving a desired value of the torque of the engine from operating variables. The desired value of the torque is made available by at least adjusting the air supply and the ignition angle of the engine. The efficiency of the engine is deteriorated in at least one operating state of the engine compared to the efficiency in operating states outside of the one operating state by retarding the ignition angle and increasing the air supply whereby the torque developed by the engine remains essentially constant. The presence of the one operating state is detected when a startup intent of the driver of the vehicle is recognized.

    摘要: A method and an arrangement for controlling an internal combustion engine of a vehicle wherein a desired torque value is pregiven, this desired torque value being separated into at least two desired values. The desired values serve to adjust the charge of the internal combustion engine and at least one further power parameter, which effects a rapid torque change. The at least two desired values assume different values at least in one operating state.

    摘要: A process for determining the combustion pressure of an internal combustion engine is proposed. Conventional processes of this type have the disadvantage that the determination methods are very costly. Furthermore, stringent requirements are made of the sensors to be used. By comparison, the process proposed here is distinguished in that the combustion pressure is calculated from the combustion chamber pressure (p(.alpha.)) determined with simple sensors, by determining the compression pressure (p.sub.k (.alpha.)). These values for the compression pressure are subtracted from the combustion chamber pressure in order to calculate the combustion pressure p*(.alpha.)). Preferably, the course of the compression pressure is obtained by measuring the combustion chamber pressure values during the compression until top dead center in the working phase and storing them in a memory. The compression values occurring after top dead center are obtained by reflection at an axis extending through top dead center, resulting in a symmetrical curve course for the compression pressure. In this way, the combustion pressure can be calculated particularly simply.
