Abstract

A vehicle control system for a motor vehicle includes functional modules for controlling elements of the vehicle, a fault management module generating confirmed fault signals from fault data, and a global management module for the operating modes of the vehicle. The global management module generates a mode signal when it detects at least one confirmed fault signal and distributes, to the functional modules, the mode signal including an instruction to the functional modules to switch the elements of the vehicle to a restricted operating mode in relation to the confirmed fault signal or signals detected.

Claims

1-10. -10. (canceled)

11. A vehicle control system for a motor vehicle, comprising:

functional modules for controlling elements of the vehicle;

a fault management module generating confirmed fault signals from fault data; and

a global management module for the operating modes of the vehicle, the global management module being configured to generate a mode signal when it detects at least one confirmed fault signal and to distribute, to the functional modules, said mode signal comprising an instruction to the functional modules to switch the elements of the vehicle to a restricted operating mode in relation to said confirmed fault signal or signals detected.

12. The vehicle control system as claimed in claim 11, further comprising:

a module for processing inputs designed to generate quantifying and/or logical data for the functional modules and fault data for the fault management module.

13. The vehicle control system as claimed in claim 11, wherein at least one of the functional modules is designed to generate quantifying and/or logical data for other functional modules and fault data for the fault management module.

14. The vehicle control system as claimed in claim 11, wherein at least two of the functional modules each include a management submodule dedicated to restricted modes to respond to said instruction in the mode signal in order to control the elements of the vehicle controlled by the functional module accordingly.

15. The vehicle control system as claimed in claim 14, wherein the management submodule dedicated to restricted modes includes at least two components for controlling the elements of the vehicle controlled by the functional module that includes the management submodule dedicated to restricted modes, and the management submodule dedicated to restricted modes includes a selector for activating one of the components as a function of the mode signal.

16. The vehicle control system as claimed in claim 11, further comprising:

a control component to control said elements in a thermal-only operating mode of the vehicle.

17. The vehicle control system as claimed in claim 11, further comprising:

a control component to control said elements in an electric-only operating mode of the vehicle.

18. A vehicle control method for a motor vehicle, comprising:

generating confirmed fault signals from fault data relating to elements of the vehicle controlled by functions; and

generating and distributing a mode signal containing an instruction to switch the elements of the vehicle to a restricted operating mode relating to said confirmed fault signal or signals detected such that several functions share the same restricted operating mode of the vehicle.

19. The vehicle control method as claimed in claim 18, further comprising:

selecting the restricted operating mode as a function of at least one element state of the vehicle.

20. A non-transitory computer readable medium storing program code instructions that, when executed by a computer, cause the computer to execute the method according to claim 18.
