Abstract

In a device for actuating vehicle assemblies, vehicle movement data is fed to a central arithmetic unit which generates the actuation signals for the vehicle assemblies. The central arithmetic unit has a plurality of software modules, a longitudinal dynamics software module which processes a component of the predefined vehicle movement data in the longitudinal direction of the vehicle, and a lateral dynamics software module which processes a component of the vehicle movement data in the lateral direction of the vehicle.

Claims

1. A device for actuating vehicle assemblies, comprising a central arithmetic unit coupled to receive vehicle movement data that is converted by means of a plurality of software modules of the central arithmetic unit to form actuation signals for the vehicle assemblies, wherein:

at least one software module of said central arithmetic unit is embodied as a longitudinal dynamics software module and processes a component of the vehicle movement data in the longitudinal direction of the vehicle; and

at least one further software module of said central arithmetic unit is embodied as a lateral dynamics software module in the lateral direction of the vehicle.

2. The device according to claim 1, wherein said central arithmetic unit further comprises at least one vertical dynamics software module that processes a component of the vehicle movement data in a vertical direction of the vehicle.

3. The device according to claim 2, wherein output signals from at least one of the longitudinal dynamics software module, the lateral dynamics software module, and the vertical dynamics software module is fed to a vehicle stability software module which regulates stability of the travel dynamics of the vehicle and generates an assembly signal for each vehicle assembly provided in the vehicle.

4. The device according to claim 3, wherein the assembly signals are transferred directly to the respective vehicle assemblies.

5. The device according to claim 3, wherein at least one of the vehicle assemblies is assigned to a software assembly module which generates actuation signals determined for the assigned vehicle assembly, based on an assembly signal of the vehicle stability software module.

6. The device according to claim 1, wherein said central arithmetic unit comprises a coordinate software module which transforms the vehicle movement data into at least one of longitudinal, lateral and vertical movement data, and transfers it to a respectively assigned longitudinal, lateral or vertical dynamics software module.

7. A device for actuating vehicle assemblies, comprising:

a single central arithmetic unit having an input for receiving vehicle movement command data;

wherein said single arithmetic unit includes,

at least one longitudinal dynamics software module that processes a component of the vehicle movement command data in the longitudinal direction of the vehicle;

at least one lateral dynamics software module that processes a component of vehicle movement command data in the lateral direction of the vehicle; and

a plurality of software modules that process signals from said longitudinal and lateral dynamics software modules to generate actuation signals for controlling respective ones of said vehicle assemblies.

8. The device according to claim 7, wherein said central arithmetic unit further comprises at least one vertical dynamics software module that processes a component of the vehicle movement data in a vertical direction of the vehicle.

9. The device according to claim 8, wherein output signals from at least one of the longitudinal dynamics software module, the lateral dynamics software module, and the vertical dynamics software module is fed to a vehicle stability software module which regulates stability of the travel dynamics of the vehicle and generates an assembly signal for each vehicle assembly provided in the vehicle.

10. The device according to claim 7, wherein said central arithmetic unit comprises a coordinate software module which transforms the vehicle movement data into at least one of longitudinal, lateral and vertical movement data, and transfers it to a respectively assigned longitudinal, lateral or vertical dynamics software module.
