Translation of "Momentenanforderung" in English

The rate of air flow may be determined from the torque requirement.

For this purpose, the engine is controlled via a torque command, namely, the shift torque Mshift.

Finally, the torque requirement is sent to the drivetrain by the vehicle supply system M_mot_anf.

Subsequent torque coordinations receive no information as to the source of the torque request.

The result of this decentral coordination is then a torque request to the drive unit.

In addition, the torque demand to the driving machine can be made uniform and can be standardized.

In FIG. 1(a) the arrows represent the direction of transmission of the torque request.

In the extreme case, it is only possible to check whether transmission control device 24 is requesting a torque.

Method according to claim 1, wherein the rate of air flow is determined from a torque demand.

As reaction to the positive torque request, a specific fuel quantity can be allocated to the engine 101 for a more rapid increase in rpm.

The torque interface merely provides a desired torque and information on the dynamics with which this torque requirement is to be adapted to control the engine.

In the characteristic field, the maximum torque requirement of the pedal, which is permissible at a specific rpm, is stored while considering torque-increasing functions such as, for example, the idle control.

The controller analyzes signal N of a rotational speed sensor and/or signal M of a pedal sensor and/or a torque request, among other things.

First, it should be noted that the module 10 close to the vehicle transmits to the digital engine control DME an engine predefinition M_v in the form of a torque request, which is used by the digital engine control DME to determine the regulated variables of the engine 13 (such as ignition, filling).

As a result, the driver assist system is then forced to transmit a torque demand to the engine to terminate the overrun cutoff, because the speed should be reduced less quickly.

The aforementioned “jerk effect” can then be quite pronounced and cause oscillations, because the engines frequently provide excessively high torques, which may then lead to an undesirable undue speed increase, so that the control function of the forward-guiding driver assist systems must then again severely reduce the torque demand or in extreme cases even apply the brake following the torque conversion.

Both connections serve to transmit a torque request (for example in the form of a signal) to internal combustion engine 10 and to electric motor 30 (preferably via a corresponding control circuit).

According to one specific embodiment, the expected driving state is detected, for example, via an accelerator pedal position or a torque request or an acceleration request by the driver or an acceleration measurement.

Of course, other and/or additional operating parameters describing the dynamics or the torque requirement of the vehicle may be considered so that, for example, the speed or an engaged gear can also be taken into consideration.

Here, the distance to the control object can be decreased or a value may be added to an acceleration or torque demand on the engine or braking system, wherein specifically the control distance may be reduced and/or the acceleration value may be selected as a function of the current distance to the preceding vehicle, and/or the pulling-out probability.

Alternatively or in addition, a load impact risk may occur for larger jumps in the setpoint torque, when the driver suddenly sets a high torque demand.

It should be noted here that the term torque requirement to the hybrid drive within the present invention refers to the actually required torque to bring the engine to its firing position, meaning that it may also refer to the torque required by the combustion engine from the electric machine and the starter, respectively, in order to make the final selection, which will be discussed in more detail below.
