Transmission schedule segmentation and prioritization

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• receive sensor data from one or more sensors of a vehicle;
• determine, based on the received sensor data, that a speed of the vehicle satisfies a predetermined criterion;
• alter a length of a transmission cycle of a communication network of the vehicle from a current length, based on the determination that the speed of the vehicle satisfies the predetermined criterion, wherein the transmission cycle comprises one or more scheduled time periods dedicated for transmitting data from respective first nodes in the communication network and one or more unscheduled time periods for transmitting data from one or more second nodes in the communication network, wherein altering the length of the transmission cycle comprises configuring the communication network of the vehicle by altering a first total length of the scheduled time periods and a second total length of the unscheduled time periods, and wherein the first total length of the scheduled time periods and the second total length of the unscheduled time periods are kept proportional;
• determine a priority value for each of the second nodes of the vehicle;
• configure the communication network based at least in part on the determined priority value of each of the second nodes;
• and
• receive data from the second nodes during the unscheduled time periods in an instance of the transmission cycle, wherein the data from the second nodes are ordered based on the determined priority value of each of the second nodes.

A method comprising, by a computing system:

• receiving sensor data from one or more sensors of a vehicle;
• determining, based on the received sensor data, that a speed of the vehicle satisfies a predetermined criterion;
• altering a length of a transmission cycle of a communication network of the vehicle from a current length, based on the determination that the speed of the vehicle satisfies the predetermined criterion, wherein the transmission cycle comprises one or more scheduled time periods dedicated for transmitting data from respective first nodes in the communication network and one or more unscheduled time periods for transmitting data from one or more second nodes in the communication network, and wherein the altering the length of the transmission cycle comprises configuring the communication network of the vehicle by altering a second total length of the unscheduled time periods and keeping a first total length of the scheduled time periods constant;
• determining a priority value for each of the second nodes of the vehicle;
• configuring the communication network based at least in part on the determined priority value of each of the second nodes;
• and
• receiving data from the second nodes during the unscheduled time periods in an instance of the transmission cycle, wherein the data from the second nodes are ordered based on the determined priority value of each of the second nodes.
