In this paper , truck ride performance models were founded based on vehicle dynamic . by comparing the different quarter - car and half - car model which founded by taking the trunnion suspension leaf spring as a whole body and separating the trunnion suspension leaf spring into two dynamic equivalent parts , we gained a more reasonable simplified model which comply with the factual performance 本文根据汽车动力学原理建立平顺性动力学模型,通过对平衡悬架弹簧作为整体的车辆模型和平衡悬架弹簧分开等效处理的1 / 4 、 1 / 2车辆模型作了比较分析,得到与实际情况比较符合的简化模型。
A fuzzy rule tab is formed . in hardware design , choicing 16 bit single - chip computer . designing singal input circuit . output driving circuit , power source circuit and forming an abs fuzzy control circuit . at last , linking the wheel modelling by virtue of 5196 simulation , experiment sesults ar e given 在硬件设计方面，根据系统选择了16位单片机，设计出信号输入回路、输出驱动回路、电源部分，形成控制器电路图并制成防抱死制动控制器，最后用串口通讯与双轮车辆模型连接。
At last , based on vehicle side - slip angle and yaw rate , 3 different kinds of vehicle handling stability controller are designed using variable structure control with sliding mode theory . at simulink simulation flat , do simulation experiment of the concept car model with the direct yaw moment control and without control ; and which control strategy should be apply in different specifically vehicle working conditions , how the vehicle velocity , steer characteristic , control parameters etc . impact the control quality have been studied 最后,运用滑模变结构控制理论,基于质心侧偏角和横摆角速度这两个控制变量分别提出三种具有针对性的控制策略,在simulink仿真平台上,对带有汽车稳定性控制器和不带汽车稳定性控制器的车辆模型进行了仿真研究;对不同工况下汽车稳定性控制策略的具体应用及车速、转向特性和控制参数等因素对控制品质的影响进行了研究。
With the development of virtual prototyping and virtual reality technology , the vehicle virtual experiment system is put forward . with virtual environment simulate complicate real environment , in virtual environment , users can control the vehicle and do experiment , experience vehicle performance and acquire the subjective response . vehicle parameters are modified and the vehicle performance is optimized 用虚拟环境来模拟复杂多变的环境，通过视觉、触觉、听觉等各种传感设备，用户既可以控制车辆模型，也可以体验车辆在各种工况下的性能，根据用户体验调节车辆的参数化模型，对其进行优化。
This paper combine the properties of railway bridge to establish the model of vehicle and three - dimension finite model of wan zhou yangtze river bridge individually , then according to the basic hypothesis and through the relations of geometry displacement compatibility and force and adopting the mode superposition to establish the coupling model of vehicles and bridge 本文结合铁路桥梁的特点，分别建立了车辆模型和万州长江大桥的三维有限元模型，根据桥梁结构的基本假设，采用模态综合法，通过轮对与轮轨之间的几何相容关系和力的关系建立了车桥耦合振动模型。
To improve dynamic performance control effect for air suspension vehicle with half vehicle model as a control object and perpendicular motion and longitudinal acceleration as control indexes , the half - vehicle model fuzzy control simulation was performed by taking grade b road as random input 摘要为了改善空气悬架客车动态性能的控制效果，以空气悬架客车1 / 2模型为控制对象，以车身垂直运动和俯仰运动加速度为控制指标，以b级路面为随机输入，应用模糊控制技术对1 / 2车辆模型进行了计算机控制仿真分析。
In vehicle classification period , because deep information is absent , it ' s a very difficult task to obtain vehicle characters from images . vehicle recognition based model match method is adopted and we can match segmentation edges and model edges with hausdorff distance . this method is not sensitive to deformation and noise 在车型判别阶段，单摄像头摄像丢失了深度信息，很难从图像中获取车辆的特征参数，本文利用车辆边缘和车辆模型相匹配的方法识别车型，匹配的好坏程度用hausdorff距离度量，这种方法对噪声和形变适应性较好。
