Analysis of cooperative driving operation of a car by two humans for the application to automatic driving system

Abstract

Automatic driving technology of cars is rapidly developed now. The driving sovereignty moves from self-driving system to a human driver under certain conditions in the level 3 of the automatic driving technology. The transfer has to perform smoothly and not to give incongruity to the human driver. Otherwise the driving behavior of the human after the transfer becomes unstable. For the development of the self-driving system, the cooperative driving behavior by two humans is analyzed from the viewpoint of energy flow in this paper. An experimental device with two steering wheels, two accelerator pedals and two break pedals were developed for the experiment of two humans cooperative driving. The experimental results show that the switching number of the energy flow direction is small in the smooth transfer operation.
