摘要： A process determines the torque transmitted by the gas forces to the crankshaft of an internal-combustion engine. The rotational speed data which is detected by determining the angular speed of a component fixedly connected with the crankshaft is analyzed, and the rotating moment is computed from the angular speed correlated with the rotational speed by way of the moment of inertia of the engine. In addition to the rotational moment of the engine, the torques of the oscillating masses, the torsional moments of the crankshaft and the static torques resulting from all slowly variable friction moments, effective moments and load moments are determined. From a balance of these individual torques, the torque resulting form the gas forces is determined. Subsequently, the work delivered by the individual cylinders per working cycle is determined from this torque. The thus determined operating parameters is used for the engine control and/or for the on-board diagnosis.

摘要： Method and device for counting clock pulses for the purpose of determining period length works in accordance with an absolute time measuring principle, provides at least a single main counter which runs uninterruptedly from the start of measurement to the end of measurement and a channel counter for each of a number n of measuring channels. By stopping a channel counter at the associated measurement period end and reading out the counter reading thereof as well as that of a supplementary upper main counter part which contains the higher-order count positions, a determination is made of the total time elapsed from the start of measurement up to the respective detected period end, and thereafter the target period lengths are determined by forming the difference of successive count values. The invention can be used, for example, for the high-precision measurement of the speed of a system rotating about an axis.

摘要： A method for performing shifting operations in an automated, mechanical transmission, which is coupled via an automated clutch to an internal combustion engine, in particular a diesel engine. The setpoint engine torque (MDsoll) is essentially predefinable by a gas pedal (10) and/or by a vehicle-speed controller or limiter (17, 18). The setpoint engine torque is varied in response to gear shifting operations through the intervention of an electronic control device, as follows: The area of the electronic control device that is designated for the transmission control is continually supplied with the setpoint engine torque MDsoll1. In response to manually or automatically introduced gear shifting operations, a switch is made to the setpoint engine torque being input by the electronic transmission control, which calculates this setpoint engine torque (GW-MD) as a function of gear-change parameters and/or extracts it from gear-change characteristics maps or curves. After completion of the shifting operation, a switch is made, in turn, to the setpoint engine torque (MDsoll1) being input by the gas pedal (10) or the speed controller or limiter (17, 18). An especially smooth and lurch-free shifting can be achieved through the close "cooperation" between transmission control and engine timing, as well as on the basis of the specific feedback information when working with automated, manual transmissions, particularly in conjunction with diesel engines.
