Abstract
With the emerging development of intelligent airports or factories, rollover accidents in autonomous heavy-duty trucks outdoors or autonomous heavy-duty forklifts indoors are getting more and more increasing. These outdoor or indoor rollover accidents must be prevented in advance of dangerous situation. This paper develops an automatic Anti-lock Brake System (ABS) to automatically interfere and confine the longitudinal speed and the gravity center of the autonomous vehicles anytime. Through monitoring both vehicle's and wheel's speeds, this proposed automatic ABS makes the autonomous vehicles keep stability control even when the wheels halt or slip on the road. This paper adopts TruckSim to model the vehicle safety dynamics and MATLAB/Simulink to simulate the vehicle stability control. Experimental results show that the elaborate automatic ABS proposed by this paper can smoothly keep the vehicle stable and tractive even under dangerous road conditions of sharp corner or hairpin turn.
