Abstract: Considering the real gradient conditions, a multi-real-time mechanics model for monitoring vehicle's safe travel speed and center of gravity based on the pressure sensor is proposed. The safe travel speed mechanical model is established based on the inffiuence of the center of gravity of the vehicle, the road vertical gradient, the horizontal gradient and the radius of curvature of the road. The mechanism of monitoring and warning the safe travel speed is studied based on the multi-dimensional mechanical model. This model can be used to calculate the safe travel speed and the center position in real time of the motor vehicles, and provide important parameters for developing the monitoring system in real time for the safe travel speed of automobiles.

Key words: a mechanics model|safe travel speed|center of vehicle's gravity|real-time monitor
