Abstract

A multi-processor architecture for automated driving systems can be used to improve performance and provide design flexibility. For example, a multi-processor architecture can be used to implement command generation and safety functionality in different processors. The command generation processor can be a high performing processor compared with the safety processor. The safety processor can verify the safety of commands output from the command generation processor and provide additional I/O channels that are typically absent on high performing processors. Additionally, processing of some sensor data can be moved to expansion modules with additional processors to reduce bottlenecks and provide design flexibility for systems with different sensing requirements.

Claims19

Dependent claims

A system comprising:

a first processor configured to:
receive first data from a first plurality of sensors;
and
generate one or more automated driving commands;
a second processor coupled to the first processor and configured to:
receive the one or more automated driving commands from the first processor;
receive second data from a second plurality of sensors;
and
verify the one or more automated driving commands received from the first processor based on the second data;
a first power supply coupled to the first processor;
and
a second power supply coupled to the second processor;
wherein the first processor is configured to generate a first reset signal to reset the second power supply when a first reset condition is detected at the first processor, and the second processor is configured to generate a second reset signal to reset the first power supply when a second reset condition is detected at the second processor.

A vehicle comprising:

one or more sensors;
a plurality of processors coupled to the one or more sensors, the plurality of processors including at least a first processor and a second processor, the first processor configured to generate one or more automated driving commands based on first data received from a first plurality of the sensors, and the second processor coupled to the first processor and configured to verify the one or more automated driving commands received from the first processor based on second data received from a second plurality of the sensors;
a first power supply coupled to the first processor;
and
a second power supply coupled to the second processor;
wherein the first processor is configured to generate a first reset signal to reset the second power supply when a first reset condition is detected at the first processor, and the second processor is configured to generate a second reset signal to reset the first power supply when a second reset condition is detected at the second processor.
