Abstract
This paper describes examination including the correspondence to abnormal and a failed state about an autonomous driving of the truck which aims at CO2 reduction and energy saving, and the human machine interface on a platoon system. As HMI for a platoon system, it proposes showing information inside and outside vehicles, and the contents are described. HMI is constructed based on them and validity is verified by the driving experiment of the early stage. Furthermore, a HMI screen is improved and the questionnaire by test-riding for the verification is described.
