Embodiment Construction

[0037] To first specifically illustrate the functional relationship, figure 1 A microcontroller system 34 is shown for controlling an electronic control unit of at least one motor vehicle system, for example a motor vehicle brake system. The microcontroller system here comprises a first dual-core microcontroller unit 1 , wherein the processors of the microcontroller unit are designed redundantly.

[0038]The microcontroller unit 1 controls, for example, the braking system of a motor vehicle and includes the control software required for this and an interface 4 for connecting peripheral devices (such as analog-to-digital converters, PWM, timers, FlexRay, CAN), wherein the microcontroller unit 1 The operating system 5 included in the controller unit 1 can communicate with corresponding peripheral devices via the interface 4 . The operating system 5 complies with standards for embedded real-time operating systems in the automotive field, for example the operating system standard...

Abstract

The invention relates to an electronic control unit (30) for controlling and / or regulating at least one motor vehicle system, comprising at least one integrated microcontroller system (34) which is intended to execute software and has at least two microcontroller units (1, 1') which each execute at least one independent operating system (5, 5'), wherein at least one interface (2) for interchanging information between the microcontroller units (1, 1') is provided, and is also distinguished by the fact that a first microcontroller unit (1) is designed to control and / or regulate a first motor vehicle system, in particular a motor vehicle brake system, and a second microcontroller unit (1') is designed to be able to provide the first microcontroller unit (1) with specifications for controlling and / or regulating the first motor vehicle system using the interface (2). The invention also comprises the use of the electronic control unit.

Description

technical field [0001] The invention relates to an electronic control unit according to the preamble of claim 1 and to the use of the electronic control unit. Background technique [0002] The complexity of the systems in modern motor vehicles is also increasing, in particular with the increasing integration of assistance functions which relieve the driver while driving the vehicle. To implement these functions, more components are required, such as sensors, which overall lead to an increased amount of information and a wide range of interconnections inside and / or outside the vehicle. Problems arising from this are, for example, ensuring fail-safety with increasing system complexity, increased system and integration costs, quality requirements to be met, increased product introduction times and production times per vehicle. For this purpose, modern multi-core microcontroller systems are usually used, which use a master-slave communication scheme. Here, the host-entity incl...
