Recent years have witnessed rapid advancement of automated driving technologies. In this context, driver-vehicle cooperation as a new interaction paradigm offers an opportunity to improve the driving performance through the exploitation of human-automation synergy. This paper presents the implementation and evaluation of a new cooperation principle between the driver and the automated driving system. Within a use case concerning highway merging management, we describe the scenario modelling, system functional and HMI design. We evaluate the cooperation principle and the designed HMI through a user study on driving simulator. Based on test results, we discuss user’s perception of the cooperation principle and the potential of this principle to handle highway merging situations. Through this paper, we also aim to demonstrate the strengths of driving simulation in terms of interaction design for automated driving systems.

The simulation workshop CHORALE of the French DGA is used by government services and industrial companies for weapon system validation and qualification trials in the infrared domain, and detection of moving vehicles in the acoustic domain. Recently, acoustic simulation tests were performed on the 3D geometrical database of the DGA/DCE/ETBS proving ground. Results have been compared to the acoustic measurements of the NATO-TG25 trials. This article describes the trials, the modeling of the 3D geometrical database and the comparison between acoustic simulation results and measurements. The 3D scene is described by a set of polygons. Each polygon is characterized by its acoustic resistivity or its complex impedance. Sound sources are associated with moving vehicles and are characterized by their spectra and directivities. A microphone sensor is defined by its position, its frequency band and its directivity. For each trial, atmospheric profiles (air temperature, pressure and humidity according to altitude), trajectories and sound spectrum of moving objects were measured. These data were used to prepare the scenario for the acoustic simulation.
