1. A vehicle control unit for a vehicle, the vehicle control unit comprising:
one or more processors;
one or more communication interfaces for communicating over a vehicle communication network; and
one or more memory resources storing instructions that, when executed by the one or more processors of the vehicle control unit, cause the vehicle control unit to:
periodically obtain high priority messages over the vehicle communication network from a plurality of electronic control units;
determine, based on a first high priority message received from a first electronic control unit of the plurality of vehicle control units, to request a set of lower priority data from the first electronic control unit;
transmit, over the vehicle communication network to the first electronic control unit, a request to cause the first electronic control unit to transmit the set of lower priority data to the vehicle control when it is determined to request the set of lower priority data from the first electronic control unit; and
obtain the set of lower priority data over the vehicle communication network from the first electronic control unit while periodically obtaining the high priority messages over the vehicle communication network.
