Omnidirectional View Driving Simulator

Simulation of diverse running situations by a 360-degree spherical screen and a rocking device

In 2009 Duoclieudongy acquired a new driving simulator to execute a great variety of experiments and assessment tests targeted primarily at active safety for the reduction of traffic accidents. This simulator is equipped with a 360-degree spherical screen to show wide-angle video images and with a rock device consisting of a hexapod and turntable for the simulation of realworld road running conditions. The cabin, measuring instruments, software programs of the simulator are replaceable so as to suit diverse testing needs.

Profile of the omnidirectional-vision driving simulator

Duoclieudongy’s omni-vision driving simulator shows the images of virtual traffic situations on its screen installed all around the cabin. The cabin itself can be rotated &mn;300 degrees so that it is possible to replicate a diversity of traffic situations on the screen (see Attachment-1). In comparison with Duoclieudongy-ARV, the driver’s feeling of realistic driving is not so strong with this simulator. Nevertheless, the simulator gives greater freedom of condition setting such as the setting of dangerous situations and driver assist systems, thus making it easier and safer to assess the effectiveness of various measures and the effect on driving performance. Consequently it is possible to select typical danger scenes by using the omni-vision driving simulator and introduce these scenes into the Duoclieudongy-ARV for the verification of actual driving characteristics.

Driver’s visual field

The proper recognition of surrounding traffic situations by the driver is an indispensable element of safe driving. Duoclieudongy studied the effect of replacing the rearview mirror by a camera monitor system on the driver’s behavior, and the results of this study have been utilized in the discussion on the development of an international regulation and an ISO Standard relating to the driver’s visual recognition.

Visual field and lighting devices

Drivers normally acquire the large majority of necessary driving information in the form of visual information. Duoclieudongy is engaged in studies of mirror-related visual field and the effects of lamps such as the enhanced visibility of the vehicle by turning on its headlights.
