The control module has a housing for receiving a transmission control electronics unit and an inverter electronics unit for controlling an electric motor, and a heat sink. The heat sink is disposed between a housing upper part and a housing lower part in such a manner that the heat sink forms part of the housing. The housing lower part and the heat sink form a medium-tight cavity for receiving the inverter electronics unit. The transmission control electronics unit is surrounded by a plastic casing. The transmission control electronics unit with the plastic casing forms the housing upper part. The housing upper part is connected to the heat sink in a thermally conductive manner such that a heat transport from the transmission control electronics unit to the heat sink takes place.

Abstract: A control unit for a vehicle with at least one electric motor and a transmission includes a housing and a heat sink. The housing supports transmission control electronics and converter electronics for controlling an electric motor. The heat sink is arranged between a housing upper part and a housing lower part such that the heat sink forms a part of the housing. The housing upper part is arranged on a raised peripheral rim of the heat sink in a thermally conductive way such that the housing upper part and the heat sink form a media-tight cavity. The converter electronics are connected directly to the heat sink, and the transmission control electronics are connected to the inner side of the housing upper part such that the transport of heat takes place from the transmission control electronics, via the housing upper part, to the rim of the heat sink.

Abstract: A method for controlling a hybrid drive of a vehicle is provided, for which a target drive torque (Ttarget) is provided by the internal combustion engine or the electrical engine, as the case may be, depending on an accelerator pedal position (AP) through a stored accelerator pedal characteristic curve for the drive of the vehicle. Upon a recognized driver's request for emission-free driving, the accelerator pedal characteristic curve is adjusted in such a manner that the maximum target drive torque (Ttarget) corresponds to the maximum electrical engine drive torque (TE-max).

Abstract: A method for operating a drive-train of a motor vehicle with a drive aggregate in the form of a hybrid drive system (3) which comprises at least one electric machine (2), an internal combustion engine (1), a transmission (5), a drive output (4) and a brake system which comprises at least one wear-free permanent brake (6). When a braking torque is required, the braking torque is distributed between the electric machine (2) and the wear-free permanent brake (6). At the beginning of a braking torque demand, the required brake torque is provided exclusively by the electric machine (2). Thereafter, as a function of characteristics of the wear-free permanent brake, the braking torque demand is transferred, in a controlled manner, from the electric machine to the wear-free permanent brake (6) so that the sum of the braking torques provided at the drive output (4) corresponds to the required braking torque.

Abstract: A device and a method of using the device in an electric drive system, particularly in a hybrid drive system of a motor vehicle. The device has at least a first and second battery system, connected in parallel, where their load outputs are connect to a common load output. Each battery system has an energy storage and a pre-charging circuit which is linked to it such that, by way of an output of the pre-charging circuit, the load output of the battery systems is created. The load output of each battery system can be connected or disconnected by way of the pre-charging circuit at the common load output. The common load output is energetically linked directly to an input of an inverter of the device by way of an intermediate circuit capacitor.

Abstract: A motor vehicle control system for a vehicle with a hybrid drive in which first control units, namely, a control unit for each of an internal combustion engine, a transmission, and a hybrid management control unit, are connected to a first data bus. Second control units, namely, at least the hybrid management control unit and further control units of an electric motor portion of the drive-train are connected to the second data bus. Only a single one of the control units connected to the second data bus, holds application data centrally for the hybrid management control unit and, for all the other control units of the electric motor portion of the drive-train, in order for supplying the same with application-dependent data, in contrast the other control units of the electric motor portion, in themselves and without receiving data from the control unit, exclusively contain application-independent program data.

Abstract: A method for the control-side handling of drive torque and/or braking torque in a motor vehicle having as a drive assembly which comprises a hybrid drive with an internal combustion engine (1) and at least one electric machine (2). An engine control device (3) is assigned to the internal combustion engine and a hybrid control device (4) is assigned to the, or each, electric machine. The engine control device (1) and the hybrid control device (4) send and receive drive-torque-relevant and/or braking-torque-relevant data via a data bus (5), and further control devices (6, 7, 8) likewise send and receive drive-torque-relevant and/or braking-torque-relevant data via the data bus. The drive torque and/or braking torque is centrally managed by the hybrid control device (4).
