The mathematic model of vehicle rollover is introduced in the paper,and the factors leading rollover are analyzed.The angle measurement circuit is designed using ADXL203,and the data is processed by the microcontroller.A protable vehicle rollover warning system is designed based on dual-axis accelerometer,which can remind the driver of the vehicle running status dynamically.The experi-mental results show that the system’s running speed is high,the measurement is accuracy,and the rollover warning function is achieved. This circuit has simple structure,high accuracy,the advantages of small volume,it can be widely used in all kinds of motor vehicle run-ning status monitoring field.
