Vehicle rollover is a fatal accident which occurs rapidly.To get accurate information of vehicle rollover timely

a dynamic rollover warning system is presented for a sport utility vehicle（SUV）.From the motion law of vehicle rollover

a three degree of freedom model is established and the dynamic rollover warning algorithm is studied for SUV.A 16-bit microcomputer is used to design the test bench of vehicle dynamic rollover warning. Some typical experimental cases are applied to analyze the system performance.The results show that the system can accurately obtain the time to rollover（TTR） in super real-time and improve vehicle anti-rollover safety.
