摘　　要：为了验证汽车纵向避撞系统的安全性和鲁棒性,本文运用Carsim建立了特定参数的车辆动力学模型,经过理论分析并利用Simulink搭建了期望节气门开度和期望制动压力输出模型,充分利用各动力总成现有的标准数据,建立了模拟汽车主动避撞系统中车辆在复杂工况的行驶过程中的纵向避撞动力学模型。在典型工况下进行仿真分析,仿真结果表明在低速和高速条件下,避撞系统都能充分发挥其避撞作用,提高行车安全性。In order to test the car collision avoidance system security and robustness, this paper use the vehicle dynamics model of Carsim was established with specific parameters.Through theoretical analysis, using Simulink to build the throttle opening and expectations desired braking pressure output model, the full use of the powertrain existing standard data, is established to simulate the automobile driving to avoid the vehicle hit systems running complex longitudinal collision dynamics model. Simulation analysis on typical conditions, the simulation results show that in the low and high speed condition, the collision avoidance system can give full play to its collision avoidance action, improve driving safety.
