Abstract:To realize vehicle stability control after tire blowout, an emergency automatic braking system was developed. After the system received a signal of tire blowout, the automatic braking system worked to decelerate vehicle to a safe speed or to stop before out of control. The breaking system could remedy the delay of driver responding and assist the tire blowout vehicle to stop safely. The fuzzy control strategy of additional yaw torque of the tire blowout vehicle was designed according to the position of target tire. The balanced torque was provided by electrical hydraulic braking(EHB) system, and the antideviating control was carried out according to the dynamic situation of vehicle. The simulating test system was also designed. The testing results show that the vehicle can be quickly stabilized and keep in original track after tire blowout with the proposed emergency braking stability control system.
