Example Embodiment

[0028] in figure 1 In the description of the embodiments and the embodiments, only the components important for the understanding of the present invention are discussed.

[0029] figure 1 An embodiment of the microcontroller system according to the present invention is shown, which is implemented as a combination of a multi-core (multi-core) and a multi-chip system on a single chip or silicon substrate. The microcontroller system here includes subsystem A and subsystem B, which can be implemented as single-core or multi-core systems, respectively, and-in addition to coupling based on a common silicon substrate-are physically separated and have separate voltage sources A11 , B11 and system clock supply devices A12, B12. In order to improve functional safety, the two subsystems A and B, for example, implement a two-channel safety architecture, including redundant cores 1A, 2A, 1B, 2B, and storage buses A13-1, A13-2, B13-1, B13-2 , RAM memories A14-1, A14-2, B14-1, B14-2 and comp...

Abstract

The invention relates to a microcontroller system for safety-critical motor vehicle systems, comprising a plurality of subsystems (A, B) arranged on a common chip (1), at least one of said subsystems having more than one channel, and being characterized in that it is designed to carry out a plurality of operating modes. The subsystems (A, B), in a first operating mode, are operated independently of each other and communicate with each other via an on-chip interface (A27, B27). In a second operating mode, at least one of the subsystems (A, B) is operated by means of data transmission means (A25, B26, A26, B26) and using non-local resources (A13-1, B13-1,..., A18) of at least one further subsystem (A, B) and/or at least one of the subsystems (A, B) is operating and at least one further subsystem (A, B) is inactive. The invention further relates to a method for operating such a microcontroller system and to the use thereof.

Description

technical field [0001] The invention relates to a microcontroller system for a safety-critical motor vehicle system according to the preamble of claim 1 , for operating a safety-critical motor vehicle according to the preamble of claim 6 Systematic approach and its application. Background technique [0002] Highly available or accident-proof vehicle systems, such as those required for automated driving applications, place increased demands on the availability and freedom of interaction of the electronic components of the individual motor vehicle systems and, in this case, in particular on the corresponding microcontrollers, The microcontroller executes the basic software of the vehicle systems run by the microcontroller. Accordingly, the aim is to minimize the probability of accidents with these vehicle systems. An example of a vehicle system for high availability or accident prevention is the braking system of a motor vehicle. A failure of such a braking system represent...
