Packet loss in vehicular networks can undermine the effectiveness of communication-based accident prevention systems. Traditionally, retransmission has been used to combat packet loss in communication networks. However, retransmission overhead is known to increase channel congestion in dense wireless vehicular networks, which increases the likelihood of packet loss due to collisions, limiting the...
Unexpected shift often occurs in the working of an automatic transmission. This paper analyzes the causes of this phenomenon and its influences on the heavy-duty vehicles' AT. The method of setting a reasonable shift delay interval and realtime detection on torque converter speed ration is proposed to solve this problem. The shift control strategy to eliminate unexpected shifts is designed and validated...
Before vehicle-to-vehicle-communication-based road safety becomes a reality, one of the challenges that needs to be resolved is efficient and timely recovery of safety packets that may be lost due to reception failure. Various types of retransmission-based recovery protocols have been proposed in the literature to address this problem. Although, retransmission can help recover some of the lost packets,...
This paper, we propose a new design of linear descriptor discrete time mechanical system control law by using model following control system (MFCS). In previous studies, a method of MFCS was proposed by S. Okubo. In this paper, the method of MFCS will be extended to discrete time descriptor mechanical system. The bounded property of internal states for control system is given and utility of this control...
Inter-vehicle communication (IVC) network has become an important topic in research for its potential advantages in enhancing traffic security and efficiency. This paper investigates the communication performance of IVC networks in two lane bidirectional traffic streams. By changing the transmission range of communication units and penetration rate of equipped vehicles, we studied several performance...
We can design linear predictive model following control system (PMFCS) with commensurate time-delay whose internal states are bounded. Time-delay widely exists among controlled objects in computer control processes, power systems, chemical processing systems, metallurgical processing systems, environmental systems and communication systems transmission systems and other industrial production activities...
The rapid development of wireless communication and information technologies has increased research interests in inter-vehicle communication system. In this paper, we study the throughput and end-to-end delay of an inter-vehicle communication system along a unidirectional dynamic traffic flow with shockwave for different transmission ranges of wireless units. We briefly introduce the traffic flow...
Combined effect of polarization mixing and differential group delay (DGD) on sinusoidal and random jitter tolerance is investigated. Requirements for tolerable DGD, loop bandwidth and loop delay are extrapolated.
