R&D for autonomous driving and platooning (FY2008-FY2012) FY2009 Annual Report
In the second year of the project, experimental vehicles were built and tests were conducted to confirm the functionality of individual key technologies that will undergo an interim evaluation in the third year. Additionally, platoon driving tests were carried out using two large trucks and the intended results were achieved. The various technical results obtained in fiscal 2009 are summarized below. "(1) Overall plan and verification testing" The plan to build three vehicles for use in platoon driving tests and one autonomous test vehicle was completed on schedule. Platoon driving tests involving two large trucks were conducted at a driving speed of 80 km/h and an intervehicle spacing of 20 m. The targeted spacing control accuracy was attained even in sudden braking maneuvers. "(2) Development of autonomous driving technologies" The design of a fail-safe computer prototype was largely completed. Gain adjustments were made to the control parameters of the automatic steering control system, and the targeted frequency response was almost entirely achieved under actual driving conditions. Moreover, a vehicle motion model and a lane-keeping control model were developed for the autonomous driving control model. "(3) Development of driving environment recognition technology" A camera-based white lane marking detection device was installed on a test vehicle for use as a passive sensing system. Automatic steering was successfully accomplished on a test course at a driving speed of 80 km/h. "(4) Development of position recognition technology" The specifications of high-resolution 3D digital road map data were designed, and measurements were made at three locations on a test course. In addition, the real-time self-position location algorithm was developed and incorporated into a position recognition system. "(5) Development of intervehicle communications technology" A communications system was developed for transmitting control signals between vehicles during platoon driving. The results of vehicle driving tests confirmed that the system delivers ample performance. "(6) Development of autonomous driving and platoon driving technologies" An algorithm was developed for intervehicle spacing control in platoon driving that incorporates in the control parameters not only the distance from the vehicle ahead but also the distance to the vehicle behind. This algorithm solved the fluctuation observed in intervehicle spacing. "(7) Development of control technologies for eco-driving" A computational fluid dynamics (CFD) simulation was conducted to investigate the effect of platoon driving on reducing aerodynamic resistance. The effect on reducing driving resistance was then estimated from the result, and a comparison was made with the effect on reducing fuel consumption as measured in platoon driving tests. The results indicated that platoon driving at a speed of 80 km/h and an intervehicle spacing of 8 m could be expected to reduce fuel consumption by approximately 10%.
