Device and method for the autonomous control of motor vehicles

摘要

The invention relates to a device for controlling the braking and/or steering and/or acceleration in a motor vehicle, wherein the device has a number of different sensor components, two diverse sensor fusion components, a man/machine interface component and a preferably intelligent actuator controller component, wherein each of these components constitutes a fault-containment unit and has a TTEthernet communications interface, and wherein all components are connected to a central TTEthernet message distribution unit, and wherein the components communicate with one another exclusively with use of standardized Ethernet messages, and wherein a diagnosis unit for time-correct monitoring of the exchanged messages can be connected to the TTEthernet message distribution unit.

1. A device for controlling at least one of braking, steering, or acceleration in a motor vehicle, the device comprising:
a plurality of different sensor components (111, 112, 113); an interface component (130); and an actuator controller component (150); wherein each of these sensor, interface, and actuator controller components constitutes a fault-containment unit and has a TTEthernet communications interface; wherein the device further comprises two separate and diverse sensor fusion components (121, 122) configured to operate in parallel to construct a model of surroundings using different software to determine a criticality index of a current scenario; and a monitor component (140) for monitoring a driver of the motor vehicle and configured to determine an engagement index of the driver; wherein each of the two diverse sensor fusion components (121, 122) likewise constitutes a fault-containment unit and has a TTEthernet communications interface; wherein all components of the device are connected to a central TTEthernet message distribution unit (100), and wherein the components communicate with one another exclusively with use of standardised Ethernet messages; and wherein the actuator controller component controls at least one of braking, steering, or acceleration in the motor vehicle based on the criticality index and the engagement index.
