Cooperative Adaptive Cruise Control (CACC) for Truck Platooning: Operational Concept Alternatives

Background

The goal of the Cooperative Adaptive Cruise Control (CACC) for Truck Platooning project is to demonstrate that truck CACC is an important step toward full truck automation. This report reviews alternative operational concepts for managing the formation and operation of truck CACC strings. While the results of the project are intended to be applicable in many circumstances, the area studied in this report is I-710 in California. This phase of truck CACC research is a partnership between Volvo North America and the California Partners for Advanced Transportation Technology at the University of California – Berkeley.

Lessons Learned

There are some key considerations in the deployment of CACC:

  • Coordination strategies for CACC should be based on local conditions. What works in one corridor may not work in another.
  • Mitigation of negative effects of cut-ins is important. These events are an issue with steady-state cruising because they cause a temporary string split maneuver and cause a disruption.
  • System states, fault conditions, and emergency kill switches must be designed to keep the DSRC broadcast active while indicating what is occurring as all following trucks will be impacted.
  • CACC systems must incorporate an ability for the lead truck driver to send instructions (e.g., lane change) or warnings (e.g., road hazards) to following trucks.
