Vehicle-to-vehicle (V2V) communication is an important part of intelligent transportation system. With the vigorous development of expressway construction, it is of great significance to study the propagation characteristics of V2V communication channels in the scene of expressway under construction. This paper describes in detail the V2V broadband channel measurement activity carried out on the A96 expressway in the suburb of Munich, Germany. Based on the measured data, the variation of signal receiving power while the vehicle was moving is analyzed. We focus on the small-scale fading characteristics of expressway sections under construction in the C-band. The results show that the magnitude of received signal varies rapidly while vehicles are moving. Comparing the measurement data with theoretical distributions, it has been found that the magnitudes of measurement data on the expressway under construction fit the best to the Rice distribution.

With the advent of autonomous vehicles, the human driver’s attention will slowly be relinquished from the driving task. It will allow drivers to participate in more non-driving related activities, such as engaging with information and entertainment systems. However, the automated driving system would need to notify the driver of upcoming points-of-interest on the road when the driver’s attention is focused on their screen rather than on the road or driving display. In this paper, we investigated whether providing directional alerts for an upcoming point-of-interest (POI) in or around the user’s active screen can augment their ability in relocating their visual attention to the POI on the road when traveling in a vehicle with Conditional Driving Automation. A user study (N = 15) was conducted to compare solutions for alerts that presented themselves in the participants’ central and peripheral field of view.

The adhesion control is the basic technology of active safety for the four-wheel driven EV. In this paper, a novel adhesion control method based on fuzzy logic control is proposed. The control system can maximize the adhesion force without road condition information and vehicle speed signal. Also, the regulation torque to prevent wheel slip is smooth and the vehicle driving comfort is greatly improved. For implementation, only the rotating speed of the driving wheel and the motor driving torque signals are needed, while the derived information of the wheel acceleration and the skid status are used. The simulation and road test results have shown that the adhesion control method is effective for preventing slip and lock on the slippery road condition.
