Effects of Communication Delay on String Stability in Vehicle Platoons
The throughput of vehicles on highways can be greatly increased by forming vehicle platoons with small inter-vehicle spacings. The control law that maintains stable operation of a platoon is dependent on the lead and preceding vehicle’s position, velocity and acceleration profiles. These profiles guarantee string stability of a platoon and are transmitted via wireless communication networks. Th...
متن کاملEvaluation of CACC string stability using SUMO, Simulink, and OMNeT++
Recent development in wireless technology enables communication between vehicles. The concept of cooperative adaptive cruise control (CACC)–which uses wireless communication between vehicles–aims at string stable behavior in a platoon of vehicles. “String stability” means any non-zero position, speed, and acceleration errors of an individual vehicle in a string do not amplify when they propagat...
متن کاملInternal and string stability analyses of longitudinal platoon of vehicles with communication delay and actuator lag under constant spacing policy
This paper studies the longitudinal control of a group of vehicles following a lead vehicle. A neighbor based upper level controller is proposed by considering communication delay and actuator lag. Constant spacing policy is used between successive vehicles. Two different approaches based on Lyapunov-Razumikhin and Lyapuniv-Krassovski theorems are presented to stability analysis...
متن کاملString-stable CACC design and experimental validation
The design, analysis and experimental validation of a Cooperative Adaptive Cruise Control (CACC) system are presented. Focussing on the feasibility of the implementation, vehicle-to-vehicle communication with the directly preceding vehicle only is considered. This communication structure is known as semi-autonomous ACC and enables ad-hoc platooning and dealing with non-CACCeqquipped vehicles in...
متن کاملFast Communication a Constrained String Method and Its Numerical Analysis∗
A constrained string method is developed to solve the saddle-point problem with constraints. Based on the intrinsic description of the string method, Lagrange multipliers are employed for treating the constraints. Various mathematical properties are established such as the conservation of the constraints and the energy dissipation law. We also investigate time discretization schemes for the con...
