Abstract
Safe operation of vehicle controllers is described. In one or more implementations, a system includes a vehicle network, a plurality of edge devices in communication with the vehicle network and operable to implement vehicle operations, and a vehicle control system in communication with the vehicle network and having at least two processors configured to redundantly control the vehicle operations implemented by the edge devices. Each of the processors is operable to self-report a respective processor health to the vehicle network for enabling each edge device to independently arbitrate to be controlled by a healthiest processor.
Claims20
A system comprising:
- a vehicle network;
- a plurality of edge devices in communication with the vehicle network and operable to implement vehicle operations;
- and
- a vehicle control system in communication with the vehicle network and having at least two processors configured to redundantly control the vehicle operations implemented by the edge devices, each of the processors executes as a continuously operating unit with executive control of the system and self-reports a respective processor health to the vehicle network, and each edge device independently arbitrates control to a healthiest processor that the edge device independently determines based on the respective processor health of each of the processors.
A vehicle control system comprising:
- at least two processors configured to redundantly control vehicle operations by communicating over a vehicle network to independently manage a same group of edge devices that implement the vehicle operations, each of the processors executes as a continuously operating unit with executive control of the vehicle control system and self-reports a respective processor health to the vehicle network, and each edge device independently arbitrates control to a healthiest processor that the edge device independently determines based on the respective processor health of each of the processors.
A non-transitory computer-readable storage medium comprising instructions that, when executed, cause a vehicle control system to redundantly control vehicle operations by independently managing a group of vehicle edge devices using at least two processors, each of the processors executes as a continuously operating unit with executive control of the system and being operable to:
- receive edge device information from the edge devices;
- receive processor information from the processors;
- determine a respective processor health based on the edge device information and the processor information;
- and
- self-report, to the edge devices, the respective processor health, and each edge device independently arbitrates control to a healthiest processor that the edge device independently determines based on the respective processor health of each of the processors.
