基于制动距离的载货汽车制动安全状态辨识方法研究

Identification Method Research of Truck Braking Safety Status Based on Braking Distance

为了研究载货汽车制动安全状态辨识方法,从载货汽车制动减速度的影响因素分析入手,建立了载货汽车的制动距离理论模型。以解放赛龙载货汽车为例,通过滑行试验对试验车辆的空气阻力和滚动阻力参数进行标定,进一步简化了该模型。继而开展实车应用研究,提出了一种新的基于制动距离的载货汽车制动安全状态的辨识方法,为载货汽车制动安全状态预警技术开发奠定了理论基础。

After the main analysis of the influence facts of truck braking deceleration,a theoretical model of truck braking distance is established.Then the model parameters is calibrated and a real applied research using a truck which is produced by FAW as a sample is conducted.Finally a new identification method of truck braking safety status based on braking distance is proposed,laying a theoretical foundation for the development of the truck braking safety warning technology.
