“…Ruch ten bywa zakłócony brakiem ciśnienia w oponie, który może być spowodowany jej uszkodzeniem albo zsunięciem się z obręczy. Brak ciśnienia jest szczególnie niebezpieczny w ruchu krzywoliniowym, ponieważ powoduje przechylenie pojazdu, obniżenie sztywności wzdłużnej, poprzecznej i promieniowej opony oraz wzrost oporów toczenia (Lozia, 2005; Blythe, Day, Grimes, 1998). Reakcja poprzeczna jezdni na oponę początkowo ją przesuwa, a następnie częściowo lub całkowicie zsuwa z obręczy.…”

“…No pressure in the tire is particularly dangerous in the curvilinear motion as reduction of the longitudinal, lateral and radial stiffness of the tire can lead to vehicle yaw. The lateral stiffness playing the most significant role, together with an increase of rolling resistance (Lozia, 2005;Blythe, Day, Grimes, 1998). The lateral response of the road on the tire first makes it shift relative to the rim, and next slip off the rim partly or completely.…”

The possibility of modelling in the PC-Crash program of the motion on curved trajectory of a car whose rear wheel tire got unsealed, which resulted in the pressure drop to the atmospheric pressure, which was followed by the tire bead slipping off the rim, is analysed. The authors, using the results of the road tests they performed, reconstructed in the PC-Crash program the actual movement of the car. Next, they performed a number of simulations applying a bilinear model of a tire of default and modified characteristics as well as a TMeasy model. The effect of the change of wheel-to-road surface friction coefficient was also analysed. To compare the simulation results, the function of quality was employed whose value is the measure of the difference between the vehicle position and orientation obtained in simulation and the real ones. The most favourable results were reached when the TMeasy tire model was applied and the friction coefficient of the deflated tire on the distance between the point of the tire slipping off the rim and stopping was reduced.

“…Therefore, a reliable analysis may not be made without considering a blowout in traffic accidents involving tyre damage. In this paper, regular passenger vehicle tyre force test results 9,15–20 were collected to estimate the related coefficients such as the rolling resistance, the longitudinal stiffness and the lateral stiffness. Based on this, the input coefficients associated with tyre blowouts were determined, and a reliable method of simulation analysis of the movement of vehicles with blowouts is proposed.…”

This paper proposes a modified bilinear tyre force model for simulations of the vehicle dynamics, which is the core part in reconstruction analysis of vehicle collision accidents. The physical parameters involved were estimated using a statistical method based on experimental test results of the tyre forces. With an appropriate setting of the input data related to a tyre blowout, a simulation analysis of the dynamics of the vehicle which had suffered the tyre blowout was performed. The developed simulation analysis results for the dynamic behaviour of a vehicle with normal tyres with total locks or with a one-wheel lock and for vehicles with tyre blowouts when driving straight or turning corresponded well to the results of other commercial programs. The reliability of these results was proved by comparing them with the corresponding data for many vehicles involved in blowout-related accidents and in particular the path travelled by those vehicles as recorded on black-box footages.

“…It is easy to cause the driver's rush irritability operation [2]; once the driver is operating improperly, the vehicle will be severely side slipped, drifted, and even overturned. So it is useful to develop an emergency braking system to slow down the velocity of the vehicle automatically and smoothly [3][4][5].…”

For the stability control and slowing down the vehicle to a safe speed after tire failure, an emergency automatic braking system with independent intellectual property is developed. After the system has received a signal of tire blowout, the automatic braking mode of the vehicle is determined according to the position of the failure tire and the motion state of vehicle, and a control strategy for resisting tire blowout additional yaw torque and deceleration is designed to slow down vehicle to a safe speed in an expected trajectory. The simulating test system is also designed, and the testing results show that the vehicle can be quickly stabilized and kept in the original track after tire blowout with the emergency braking system described in the paper.
