چکیده
Considerable experimental and theoretical research has been carried out in an attempt to design an automated highway system that can provide more eecient utilization of the highways and at the same time be safer and more comfortable than the current highway system. Here we present a uniied framework for carrying out safety calculations for the automated highway problem. We obtain suucient conditions for a set of continuous controllers to be safe and use these conditions to design a discrete scheme that switches between them. Guarantees of safety for the closed loop, hybrid system follow by design.

Driving/Regeneration and Stability Enhancement of a 4WD Hybrid Vehicles Using Multi-Stage Fuzzy Controller
In front wheels driven vehicles, fuel economy can be obtained by summing torques applied to rear wheels. On the other hand, unequal torques applied to rear wheels provides enhanced safety. In this paper, a model with seven degrees of freedom is considered for the vehicle body. Thereafter, power-train subsystems are modeled. Considering an electrical machine on each rear wheel, a fuzzy controlle...
متن کاملVerified Hybrid Controllers for Automated Vehicles - Automatic Control, IEEE Transactions on
The objective of an Automated Highway System (AHS) is to increase the safety and throughput of the existing highway infrastructure by introducing traffic automation. AHS is an example of a large scale, multiagent complex dynamical system and is ideally suited for a hierarchical hybrid controller. We discuss the design of safe and efficient hybrid controllers for regulation of vehicles on an AHS...

Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...
