Embodiment Construction

[0033] FIG. 1 shows in a schematic illustration a schematic flow diagram of the control of a drive system of a vehicle according to the prior art, wherein the drive system together with its control unit is marked with the reference numeral 10 . The vehicle is a conventional motor vehicle, which is not shown in the figures. The vehicle has a first and a second axle, which are each equipped with wheels at their ends. FIG. 1 shows a pedal 14 , which is currently designed as a foot pedal and is intended to be actuated by the driver in order to predetermine a desired drive torque. The pedal 14 is thus an electromechanical converter which generates a signal corresponding to the user's actuation and provides this signal in the drive system. This signal represents the drive torque specified by the driver of the vehicle. The drive torque M FW It is marked with reference numeral 16 and serves to control a first electric machine 12 which drives a first axle of the vehicle in a regulat...

Abstract

The invention relates to a method for controlling a drive (40) of a vehicle with at least one first axle which is occupied by at least one wheel. A drive torque (16) is specified by a driver of the vehicle, and the first axle is driven by means of a first electric machine (12) dependent on the drive torque (16). A second electric machine (26) which is coupled to at least one internal combustion engine (30) provides electric energy for the purpose of driving the first axle by means of the first electric machine (12). A respective control or target torque (28) assigned to the second electric machine (26) and the internal combustion engine (30) is calculated while taking into consideration the drive torque (16) and machine parameters of at least the second electric machine (26), and the second electric machine (26) and the internal combustion engine (30) are each regulated with respect to the assigned control torque or with respect to the assigned target torque (28).

Description

technical field [0001] The invention relates to a method for controlling a drive train of a vehicle having at least one first axle with at least one wheel, a drive torque being predetermined by a driver of the vehicle and by means of a first electric machine according to the specified The drive torque drives the first axle, and a second electric machine coupled to the at least one internal combustion engine provides electrical energy for driving the first axle via the first electric machine. Furthermore, the invention relates to a vehicle with a drive system and a computer program product. Background technique [0002] Vehicles of the type mentioned at the outset are already known in principle, so that no separate documentation is required for this purpose. Vehicles, also known as motor vehicles, are used for locomotion on land. If an internal combustion engine is additionally provided as a drive system in addition to an electric machine as a drive system, such a vehicle i...
