| Abstract(in English) | Autonomous driving technologies have dramatically progressed these years. One of the challenges to autonomous driving is disengagement caused by unexpected situations such as occurrences of construction sites, passing of emergency vehicles. In case of disengagements, autonomous vehicles with no driver stall and prevent passage of the other vehicles. Remote control techniques are proposed to resolve stall of autonomous vehicle because of disengagement and can make recovery time of a disengaged autonomous vehicle shorter than the other approaches such as roadside assistance service. Cellular networks are suitable for remote control because of their wide coverage compared with other networks. But they also have disadvantage of unstability of communication quality. In this report, we propose two schemes for remote control of autonomous driving vehicles based on the communication quality of the area where disengagement occurs. Multi-route communication scheme is applied when disengagement occurs in the area where communication quality is high. It aggregates plural carrier’s cellular networks and virtually offer a highly reliable cellular network to the remote driving system where a vehicle sends real time streaming video around it to the remote center and the remote center sends control commands which is input by the operator to the vehicle through the cellular networks. Remote driving support scheme is applied when disengagement occurs in the area where the communication quality is low. In the scheme, a vehicle sends low rate video to the remote center, the remote center sends the path information which is input by the remote operator. The vehicle autonomously drives based on the path information. As the amount of data transmitted between the vehicle and the remote center is small, the remote control can be done in the area where cellular communication quality is low. We prototyped the remote control system which was implemented the proposed schemes, and evaluated the effectiveness of the proposed scheme. |
