1. A hierarchical diagnostics electrical architecture for a vehicle, the vehicle comprising a plurality of on-board computing devices for hosting the hierarchical diagnostics electrical architecture, and the hierarchical diagnostics electrical architecture comprising:
a component diagnostic layer comprising a plurality of electronic control units each comprising a diagnostics server module arranged to:
receive sensor output data from one or more on-board vehicle sensors;
perform one or more diagnostic tasks based on the received sensor output data to generate one or more component-level diagnostic notifications;
at least one supervisory diagnostic layer arranged to:
receive the component-level diagnostic notifications from each of a group of the plurality of electronic control units;
aggregate the received component-level diagnostic notifications to generate a supervisory-level diagnostic notification, wherein the generated supervisory-level diagnostic notification is a reaction amendment or inhibition signal sent to one or more of the electronic control units in the component diagnostic layer.
