Distributed Formation Control Algorithm for Improved String Stability in Heterogenic 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 Issues in Distributed Systems of Vehicle Platoons

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Direct adaptive longitudinal control of vehicle platoons

An important aspect of an automated highway system design is the synthesis of an automatic vehicle following system. Associated with automatic vehicle following systems is the problem of the stability of a string of vehicles, i.e., the problem of spacing error propagation, and in some cases, amplification upstream from one vehicle to another, due to some disturbance at the head of the string. R...
