Trajectory control of vehicles during a tyre blowout: A simulation study
In this paper, the experiment of trajectory control of vehicle during a tyre blowout is carried out. Firstly, the evaluation criteria of motion vehicles during a tyre blowout are determined. Then, motion vehicle with a static PID controller in highway is discussed. Simulation results show that the static PID controller determined at a certain speed is not fit for the other speed as well. Instead, a gain scheduling PID controller is adopted to handle the trajectory control problem of vehicles during a tyre blowout, where parameters of the gain-scheduling PID controller are calibrated with the varying speed. It shows that the vehicle can avoid yawing as well as keep the driving stability during the tyre blowout, and drive back to the original path after a small offset.
Theory and experiments of tire blow-out effects and hazard reduction control for automated vehicle lateral control system
This paper concentrates on the scenario of tire blow out and it's effects on lateral control of automobiles in an IVHS environment. A computer model for the tire burst phenomenon was developed to simulate the behavior of a car with a tire blow out. Based on this modeling, a control algorithm to compensate for the tire blow out was designed. Finally the tire burst experiments were conducted on a car to validate the tire burst model.
An Optimization Approach to Occupant Safety and Fuel Economy in Vehicle Design
1. Abstract A major challenge in automotive design is the creation of safe vehicles with minimal environmental impact. This study presents a modeling framework for evaluating and optimizing body designs for improved occupant safety and fuel efficiency. Vehicle body mass is considered as the main link between safety and sustainability. The modeling framework includes frontal crash energy absorption, restraint system design and fuel economy. Preliminary results indicate a Pareto-optimal curve between safety and sustainability may exist when other factors are not taken into account. A more complete modeling framework that includes more sophisticated sustainability and safety metrics, cost and other market considerations, is suggested in order to support better design and regulatory decisions. 2.
