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.
Drag and Steering Effects From Disablements of Run Flat Tires
This paper is the third part of a series of vehicle tests designed and conducted in order to further the understanding of vehicle handling and responses associated with a tire disablement event. Under inflated or deflated tires are known to cause increased forward drag and lateral steering effects on vehicles. These effects are commonly suggested to be the cause of driver loss of control and subsequent vehicular accidents. The increased drag and induced steering effects of under inflated and deflated tires are frequently an issue in an accident reconstruction. This publication addresses a series of tests which were conducted to obtain comparative drag and lateral steering effects after the disablement of current generation zero pressure, or run flat, type of tires such as those equipped on some upper end vehicles in recent years. These tests were conducted in accordance with the test protocol defined in SAE 970954. Vehicle handling and response characteristics were evaluated during and after a disablement of a zero pressure run flat tire. (A) For the covering abstract see ITRD E106540.
