Determination of Reliability of Vehicle Control Commands via Redundancy

A vehicle, comprising:

• a control element;
• at least two computing devices having redundant functions in generating commands during autonomous driving of the vehicle, the command to be effectuated by the control element of the vehicle;
• a command controller coupled between the control element and the two computing devices, wherein in response to receiving two commands from the two computing devices, the command controller:
• determines whether the two commands match with each other;
• and
• based on a result of determining whether the two commands match with each other, performs one of:
• initiating memory tests on the computing devices in response to a determination that the two commands do not match with each other;
• and
• forwarding one of the two commands for execution via the control element of the vehicle without the memory tests in response to a determination that the two commands match with each other.

A non-transitory computer storage medium storing instructions which when executed by a controller of a vehicle causes the controller to perform a method, the method comprising:

• receiving, in the controller, two commands respectively from two computing devices configured on the vehicle, the two commands configured to adjust operations of a control element of the vehicle, wherein each of the two computing devices having a memory, at least one processor, and firmware stored in the memory and executed in the at least one processor to generate a respective one of the two commands;
• determining, by the controller, whether the two commands match with each other;
• and
• based on a result of the determining, performing one of:
• initiating memory tests on the computing devices in response to a determination that the two commands do not match with each other;
• and
• forwarding one of the two commands for execution via the control element of the vehicle without the memory tests in response to a determination that the two commands match with each other.
