Abstract
According to one aspect, bandwidth associated with a vehicle communication network, such as a controller area network (CAN), is allocated by assigning priorities to systems in an autonomous vehicle which use the vehicle communication network to communicate with a vehicle control unit (VCU). Systems with high priority levels may exchange data or information with a VCU at substantially all times, while systems with lower priority levels may exchange data or information with the VCU substantially only when that data or information is requested or otherwise needed. A significant percentage of the bandwidth of the network may be allocated for the exchange of data between high priority systems and a VCU, while the remaining percentage of the bandwidth may be allocated for the exchange of data between lower priority systems and the VCU when needed. As a result, the bandwidth associated with the network may be used efficiently.
