Abstract:

Cooperative Adaptive Cruise Control (CACC) provides an intermediate step toward a longer-term vision of trucks operating in closely-coupled automated platoons. One distinction between CACC and automated truck platooning is with CACC, only truck speed control will be automated using Vehicle-to-Vehicle communication. The drivers will still be responsible for actively steering the vehicle, lane keeping, and monitoring roadway and traffic conditions. A CACC system was implemented on three Volvo Class-8 truck tractors and was tested under a variety of conditions to assess its potential impacts. The control system performance has been tested to demonstrate its ability to maintain accurate spacing between the trucks and to respond safely to cut-in maneuvers by drivers of other vehicles. The energy saving potential of the close formation driving of the trucks has been tested through an extensive set of test-track experiments. It showed that the closer separations and trailer aerodynamic improvements make a significant contribution to fuel economy. Truck driver responses to the CACC system were assessed through an on-road experiment with truck drivers, who provided their opinions about the system and about which gap settings they preferred to use while driving in mixed public traffic on California freeways. The larger-scale impacts of truck CACC on traffic flow and energy consumption were done in computer simulation. It showed the potential to relieve traffic bottlenecks and improve the speed and smoothness of traffic for all vehicles on the freeway as well as reducing fuel use and emissions.
