Embodiment Construction

[0035] figure 1 A motor vehicle 1 is shown schematically with a drive system 2 which essentially has a drive motor 3 , for example in the form of an internal combustion engine or an electric motor, which is operated via a control unit 4 to provide an output torque or motor power.

[0036] The control device 4 receives data on the driver's desired torque, for example from the accelerator pedal unit 5 , wherein the data on the driver's desired torque can be given by the position of the accelerator pedal of the accelerator pedal unit 5 caused by the driver of the motor vehicle. .

[0037] An auxiliary unit 7 is mechanically coupled to the output shaft 6 of the drive motor 3 , so that mechanical power can be absorbed by the auxiliary unit 7 . In this way mechanical power is supplied to the auxiliary unit 7 . Such an auxiliary unit 7 is, for example, an air-conditioning system which is directly coupled to the drive motor 3 and which converts the mechanical power into cooling pow...

Abstract

A method for operating a drive system for a motor vehicle having an accessory component coupled to a driving motor of the drive system, in particular an air conditioning system, including the following: ascertaining a road resistance of a route section lying ahead in the direction of travel; and adapting a power supplied to the accessory component as a function of the road resistance in the route section ahead of the vehicle; in which the power supplied to the accessory component is adapted as a function of a time period until the route section lying ahead of the vehicle is reached or of a distance from the route section lying ahead of the vehicle.

Description

technical field [0001] The invention relates to a motor vehicle with a drive system, wherein a drive motor of the drive system provides mechanical power for traction of the motor vehicle and for driving auxiliary units, such as an air conditioning system. The invention relates in particular to an operating strategy for operating a drive system with limited available power. Background technique [0002] In conventional vehicles with an internal combustion engine, the torque provided by the internal combustion engine is used not only to tow the vehicle, but also to drive auxiliary units, for example air conditioning by means of an air conditioning system. [0003] During the driving of the vehicle, different driving states occur which require different drive powers of the internal combustion engine for traction of the vehicle. For example, the required drive power is significantly greater when driving uphill than when driving straight ahead or downhill. In the case of an add...
