Patent ID: 8386142

Claim:
A motor vehicle control system for controlling a motor vehicle with a hybrid drive comprising an internal combustion engine and an electric motor, the vehicle control system comprising: a plurality of functional components, each divided into at least three sub-components, and the three sub-components comprising a strategy sub-component ( 8 ), a control sub-component ( 9 ) and an actuator sub-component ( 10 ); the plurality of the functional components including at least an internal combustion engine functional component ( 2 ) for controlling the internal combustion engine, a transmission functional component ( 3 ) for controlling a transmission, and a dedicated hybrid functional component ( 4 ) for controlling only the electric motor and a clutch connected between the internal combustion engine and the electric motor; the strategy sub-component ( 8 ) of the hybrid functional component ( 4 ) comprises an operating status prescription module which determines a prescribed value for the operating status of the hybrid drive and transmits the prescribed value to the control sub-component ( 9 ) of the hybrid functional component ( 4 ); and the control sub-component ( 9 ) of the hybrid functional component ( 4 ) comprises a first module ( 18 ), a second module ( 23 ), and at least one operative function module ( 24 ); wherein the first module ( 18 ) generates a target value for a drivetrain condition of the hybrid drive from the value for the operating status of the hybrid drive prescribed by the operating status prescription module; the second module ( 23 ) selects at least one operative function module, which contains control sequences for implementing the target value for the drivetrain condition, on the basis of the value prescribed for the drivetrain condition; the strategy sub-component of each other functional component determines at least one prescribed value for the control sub-component of the respective functional component, and determines data for influencing the strategy sub-component of at least one other functional component and the control sub-component of at least one other functional component; the control sub-component, of each other functional component, checks each prescribed value provided by the strategy sub-components of the respective functional components and determines at least one target value for the respective functional components, and determines data for influencing one of the strategy sub-component for the respective functional component and the control sub-component of at least one other functional component, and the sub-component serves to feed back at least one current actual parameter value to the strategy sub-component of the respective functional component; and the actuator sub-component, of each functional component, implements each target value, and feeds back at least one current actual parameter value to the control sub-component of the respective functional component.
