Embodiment Construction

[0014] The invention relates to a vehicle control system for a vehicle with a hybrid drive. The hybrid drive has an internal combustion engine, an electric machine and an electrical energy store, wherein the electric machine of the hybrid drive can be operated as a motor and as a generator. During motor operation of the electric machine, the electric machine converts electrical energy into mechanical energy when the electrical energy store is discharged. In generator operation of the electric machine, the electric machine converts mechanical energy into electrical energy while charging the electrical energy store.

[0015] figure 1 The basic structure of a vehicle control system for a vehicle with a hybrid drive is shown, wherein first control devices 2 , 3 , 4 and 5 are coupled to first data bus 1 . The control devices 2 , 3 , 4 and 5 are control devices that can also be built in vehicles with a conventional drive, thus for example an engine control device 2 for controlling...

Abstract

The invention relates to a motor vehicle control system for a motor vehicle having a hybrid drive system, wherein first control devices, namely at least one engine control device associated with a combustion engine of the hybrid drive system, a transmission control device (7) associated with a transmission, and a hybrid management control device (6), are connected to a first data bus (1), wherein two control devices, namely at least the hybrid management control device (6) and further control devices (9, 10, 11, 12) of an electric motor drivetrain component, are connected to a second data bus (8)and wherein exclusively a single one of the control devices for the hybrid management control device (6) connected to the second data bus (8) and all further control devices of the electric motor drivetrain component provide central application data for supplying application-specific data, while the other control devices of the electric motor drivetrain components integrally comprise exclusively non-application-specific program data without data supply via said control device.

Description

technical field [0001] The invention relates to a vehicle control system according to the preamble of claim 1 for a vehicle with a hybrid drive comprising an internal combustion engine and an electric machine. Background technique [0002] In conventional vehicles with only an internal combustion engine as drive unit, all control units of the vehicle are connected to at least one common data bus, wherein a plurality of control units send and / or receive data via one or each common data bus . This data bus is also designated as the CAN data bus. In this case, the control units, in particular the engine control unit, the transmission control unit, the diagnostic control unit, the brake management control unit and the control unit for driving speed regulation, are connected to one or each common data bus. [0003] In modern vehicles, which have a hybrid drive with an internal combustion engine and an electric machine as the drive unit, there are further control units besides t...
