摘　　要：考虑实际坡度条件下,提出了基于压力传感器的汽车重心与安全车速实时监测系统的多元力学模型.建立了考虑车辆重心高度、路面纵横双向坡度及路面半径等因素的车辆安全车速控制力学模型,并在三维模型分析的基础上提出监测与报警机理,可为汽车安全系统提供安全车速与重心计算的多维力学模型,为研制汽车安全车速实时监测系统提供了必要参数与依据.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 influence 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.
