TORQUE DETERMINATION IN AUXILIARY CONSUMERS

Abstract

The present disclosure relates to an arrangement comprising a motor, a transmission, a transmission control unit and an auxiliary user, the motor being rotatably connected to the transmission and the auxiliary user. The transmission control unit is designed to determine a torque applied to the transmission by using a parameterisable function, wherein the function maps rotational speeds of the motor to a torque applied to the auxiliary user at the rotational speed.

Claims

1. An arrangement comprising: an engine, a gearbox, a gearbox control unit and an auxiliary consumer; wherein the engine is rotationally connected to the gearbox and the auxiliary consumer; and wherein the gearbox control unit is designed to determine a torque applied to the gearbox using a parameterizable function; and wherein the function maps rotational speeds of the engine to a torque applied to the auxiliary consumer at the respective rotational speed.

2. The arrangement as claimed in claim 1 further comprising: a further control unit; wherein the further control unit sends information relating to the activation status of the auxiliary consumer; and wherein the gearbox control unit is designed to receive the information and to determine the torque applied to the gearbox using the function when the auxiliary consumer is activated.

3. The arrangement as claimed in claim 1 further comprising: a further control unit; wherein the further control unit is designed to determine the torque applied to the auxiliary consumer and to transmit this periodically to the gearbox control unit; and wherein the gearbox control unit is designed to determine the torque applied to the gearbox using the function when the transmission of the torque applied to the auxiliary consumer does not occur.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A preferred exemplary embodiment of the present disclosure is illustrated in FIG. 1.

[0034] Specifically, FIG. 1 shows a drive train.

DETAILED DESCRIPTION

[0035] The drive train 101 illustrated in FIG. 1 comprises an engine 103, a gearbox 105 and an auxiliary consumer 107. The engine 103 drives both the gearbox 105 and the auxiliary consumer 107. The output power of the engine 103 is branched accordingly.

[0036] An output torque provided by the engine 103 is divided into a first torque 109a and a second torque 109b. The first torque 109a is applied to an input shaft of the gearbox 105. Accordingly, the second torque 109b is applied to an input shaft of the auxiliary consumer 107. The output torque of the engine is derived from the sum of the first torque 109a and the second torque 109b.

[0037] To determine the first torque 109a from the output torque provided by the engine 103, the second torque 109b must be known. The second torque 109b is therefore determined by means of a function which maps the rotational speed of the engine 103 and the second torque 109b to one another.
