Controller Synthesis for String Stability of Vehicle Platoons

Controller synthesis for string stability of vehicle platoons

Cooperative adaptive cruise control (CACC) allows for short-distance automatic vehicle following using intervehicle wireless communication in addition to onboard sensors, thereby potentially improving road throughput. In order to fulfill performance, safety, and comfort requirements, a CACC-equipped vehicle platoon should be string stable, attenuating the effect of disturbances along the vehicl...

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...

Stability of Connected Vehicle Platoons with Delayed Acceleration Feedback

Wireless vehicle-to-vehicle communication technologies such as the dedicated short range communication (DSRC) may be used to assist drivers in sensing and responding to impalpable information such as the precise acceleration of vehicles ahead. In this paper, we investigate the impact of delayed acceleration feedback on traffic flow using a nonlinear car-following model. It is shown that acceler...
