Roll Stability Early Warning System Based on Tilt Sensor

Abstract

In view of the over-speed phenomenon of heavy haul vehicles at high speed, the estimation of the effective range of the dynamic stability and inclination angle of the truck was carried out a rollover stability alarm system based on liquid pendulum angle sensor and virtual instrument software was developed. The working principle and data processing module of tilt sensor are discussed, through the data lines to output analog voltage signal transmitted to the vehicle electronic control unit. A control command is sent by the electronic control unit and sent to the driver via an alarm device, which enables the driver to control the speed in time, and so it reduces the risk of a rollover accident. The results show that the warning system is of good accuracy. The early warning system preventing malignant road traffic accidents has important social significance and actual application value for a safe vehicle.
