Devices, systems, and methods for transmitting vehicle data

A method for communicating information between vehicles, comprising:

• receiving first vehicle data from a first vehicle at a platooning electronic control unit (PECU) included in a second vehicle, wherein the first vehicle data contains at least in part torque data, and wherein the first vehicle data comprises data provided by a first vehicle engine electronic control unit (EECU), a first vehicle brake electronic control unit (BECU), a first vehicle transmission electronic control unit (TECU), and a first vehicle retarder electronic control unit (RECU), and wherein the PECU included in the second vehicle is remote from an EECU included in the second vehicle;
• and
• determining at least one action at the second vehicle based in part on the received first vehicle data.

A system for maintaining a target gap between a plurality of vehicles, the system comprising:

• a first vehicle configured to transmit data, wherein the data is at least in part provided by an engine electronic control unit (EECU) included in the first vehicle, a brake electronic control unit (BECU) included in the first vehicle, (3) a transmission electronic control unity (TECU) included in the first vehicle, and (4) a retarder electronic control unit (RECU) included in the first vehicle, and wherein the data is at least in part associated with an amount of torque;
• and
• a second vehicle configured to receive the data at a platooning electronic control unit (PECU) included in the second vehicle, wherein the PECU included in the second vehicle is remote from an EECU included in the second vehicle, and wherein the second vehicle performs an action based at least in part on the transmitted data and information associated with a target gap.
