Shared Steering Control of Tire Blowout for Ground Vehicles

As a significant threat to vehicle stability and road safety, tire blowout, which is still inevitable nowadays as an emergent situation, needs to be properly controlled for vehicle stabilization. This paper proposes a novel shared control strategy to stabilize vehicles with active safety systems (e.g. SAE driving automation Level 2 and 3) after a tire blowout event, which enables a human driver to cooperate with a normal automatic controller for path following under a dynamic control authority allocation strategy. Driver-related and safety-related factors in the event of tire blowout are explicitly considered in a dynamic control authority allocation function. Matlab/Simulink and CarSim^® co-simulation results validate that the proposed shared control is promising in enhancing vehicle directional stability and driving safety after tire blowout even with a bad (panicked) driver input.
