Abstract
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.
Highlights
Tire blowout is one of the main factors which cause the fatal traffic accidents
For the situation of urgent tire blowout, the characteristics of vehicle motion will be changed after tire blowout
A tire blowout automatic braking system is developed, which can slow down the vehicle automatically to a safe speed and stop the vehicle before going out of the driver’s control
Summary
The tire pressure monitoring system (TPMS) is popularly equipped on vehicles to prevent low tire pressure and avoid tire failure accidents. It can only remind the driver of slow tire pressure failure [1]. A tire blowout automatic braking system is developed, which can slow down the vehicle automatically to a safe speed and stop the vehicle before going out of the driver’s control. By using this system, it can offset the driver’s delayed braking and help the tire-failed vehicle slow down safely
