Fail-safe EE architecture for automated driving

摘要

A system with a first computer unit and with a second computer unit, wherein the first computer unit comprises a first interface to enable connection to at least one sensor and to at least one actuator, wherein the second computer unit comprises a second interface to enable connection to at least one sensor and to at least one actuator, wherein the first and the second computer units can be connected to each other by means of a further interface, wherein the actuator comprises an interface, wherein depending on the first or on the second operating state the interface determines whether a control command for a driving function is adopted by the first or the second computer unit, so that in the first operating state only the first computer unit can activate the actuator and in a second operating state only the second computer unit can activate the actuator.

1. A system comprising:
a first computer unit having a first interface configured to connect to a sensor and to an actuator; a second computer unit having a second interface configured to connect to the sensor and to the actuator; a third interface configured to connect the first computer unit and the second computer unit to each other; and a human-machine interface configured to transfer a handover request for performance of an automated driving function by means of separate interfaces to the first computer unit and the second computer unit, the first computer unit and the second computer unit being configured to mutually and separately indicate a takeover of the automated driving function to the human-machine interface, the human-machine interface being configured to only transfer the automated driving function to the first computer unit if each of the first computer unit and the second computer unit indicate that they are operating correctly and can perform the automated driving function, wherein at least one of the first computer unit, the second computer unit, and the actuator are configured to control which of the first computer unit and the second computer unit can effectively activate the actuator.
