Implementation and Test of DSRC Standard on a Wireless Communication-Based Active Safety System

In this paper, we study the effect of the dedicated short range communication (DSRC) system on the stability of an articulated heavy vehicle that is using active trailer steering to improve the lateral stability under a double lane change maneuverability test. Several design parameters of the communication system such as modulation, quantization, channel estimation algorithm and transmit diversity have been studied and the effect of each parameter on the active control system is illustrated through simulations. The numerical evaluations show that, by adopting proper configurations, the wireless communication system can perform as good as the wired system it replaces in terms of successfully stabilizing the vehicle.
