Effects of communication delay on string stability in vehicle platoons

Fuel-saving potentials of platooning evaluated through sparse heavy-duty vehicle position data

“…Studies using probe data have been conducted for map-matching algorithms [5]- [7], path inference [8], [9], and travel time estimations and predictions [10]- [12]. Many aspects in platooning has been studied, such as string stability [13]- [15], vehicle control [16], vehicle-to-vehicle (V2V) communication [17], and fuel savings [18], [19]. For surveys of vehicle platooning and architectures, see [20], [21].…”

A guaranteed cost control for autonomous vehicle platoon with communication constraints

“…Corresponds to this case in [7], the system is unstable in Fig.2. The maximum absolute spacing error and acceleration are 2.7m and 6.5 2 s m which are much higher than in Fig.3.…”

“…Up to now, there have been several researches in this field. For example, in [7] examined the robustness of current longitudinal controller designs to communication delays; in [8] proposed an H optimal controller and derived necessary and sufficient LMI conditions for the H controller with packet-losses during communication. However, the quantization and time-delay were not considered.…”

“…In this section, we use a five-vehicle platoon to synthesize the control law which is designed in previous section and compares the result to a PID controller [7] …”

Evaluation of a low-overhead forwarding algorithm for platooning

“…Communication delays can seriously compromise string stability [4]. In 2010, IEEE 802.11p [5] at 5.9 GHz was proposed as the wireless standard for ITS applications, including data exchange between vehicles travelling on the road and the infrastructure.…”
