Embodiment Construction

[0029] figure 1 A simplified operating range of an internal combustion engine, in particular a diesel motor, is shown, which is stored, for example, in a combined characteristic curve. from in figure 1 The operating point can be read out in the operating range shown in . The x-axis shows the rotational speed and the y-axis shows the torque or load. exist figure 1 The gray area 2 shown in and the hatched area 3 are operating ranges in which the regeneration process of the exhaust gas catalytic converter cannot be carried out without the use of an electric motor, because there are in particular the temperature of the exhaust gas The condition was not met.

[0030] The use of the electric motor as part of the hybrid drive shifts the operating point of the diesel motor towards higher loads by converting the excess mechanical power of the diesel motor into electrical power. This electrical energy is then buffered, for example in a battery. This displacement of the working poi...

Abstract

The invention relates to a method for operating a hybrid drive device comprising a renewable catalytic converter in a motor vehicle. In order to operate the hybrid drive device (37) in the motor vehicle (30), the hybrid drive device (37) comprises at least one internal combustion engine (31) and at least one motor (36), wherein the motor vehicle (30) comprises a renewable exhaust gas catalytic converter (35) in the operating process of the motor vehicle (30), a proposal is provided herein, a following method is adopted to operate the motor (36) in the regeneration process of the exhaust gas catalytic converter (35): the motor genrates extra load, an operating mode capable of realizing power temporary provide capacity and a following way are adopted to operate the motor (36) in a limit duration at least before the start of the regeneration process: the temperature of the motor (35) and / or the temerature of an element for controlling the motor (36) do not over a pregiven temperature value when the regeneration process starts.

Description

technical field [0001] The invention relates to a method for operating a hybrid drive in a motor vehicle, wherein the hybrid drive comprises at least one internal combustion engine and at least one electric machine, and wherein the motor vehicle has Regenerated exhaust gas catalytic converter. [0002] Furthermore, the invention relates to a control and / or regulating device for a hybrid drive in a motor vehicle. The invention also relates to a computer program for a control and / or regulating device for a hybrid drive in a motor vehicle. Background technique [0003] In order to improve the efficiency of motor vehicles during operation, hybrid drives are used in series vehicle construction, which mainly use electric drives in addition to internal combustion engines. This is achieved by reducing fossil fuel consumption and increasing power in the lower rev range. [0004] In order to reduce the pollutants in the exhaust gas of internal combustion motors which are part of hy...
