AI Technical Summary
Technical Problem
Existing control unit systems in vehicles, such as electronic braking systems, suffer from functional deterioration due to improper replacement of components, leading to potential brake failures and operational hazards.
Method used
Incorporation of an ASIC with cryptographic functions in the control unit to authenticate and verify the identity of connected system components, restricting vehicle function if an unauthorized component is detected, and implementing a limp-home mode to ensure safe operation.
Benefits of technology
Prevents functional deterioration by ensuring only authorized components are used, reducing operational hazards and ensuring safe vehicle operation by shutting down or limiting functionality if unauthorized components are detected.

Abstract
The invention relates to a controller, to a controller system, and to a vehicle, in particular the invention relates to a controller, to a controller system, and to a vehicle in which unauthorized replacement of controller system components is more difficult. In particular, a controller for a utility vehicle is disclosed, comprising: a microcontroller and an ASIC, wherein the controller has an interface by means of which the controller can be connected to a data communication means such that the microcontroller and the ASIC can transmit data via the data communication means, the ASIC provides cryptographic functions via which the configuration or the identity of a system component connected to the data communication means such that data can be transmitted between the system component and the ASIC can be determined, the ASIC has stored information by means of which it can be determined whether the configuration or the identity of the system component belongs to an approved system component, and the ASIC comprises means for restricting the function of the utility vehicle if it is determined, by the ASIC, that the identity of the system component or the configuration thereof does not belong to an approved component.
