用于自适应巡航控制的汽车纵向动力学模型的建立

Setup of vehicle longitudinal dynamic model for adaptive cruise control

为了实现汽车自适应巡航控制(ACC)的目的,在已有制动系模型的基础上,引入发动机二状态模型,给出了驱动与制动的切换标准,建立了汽车纵向动力学模型,并以Santana轿车参数为例建立了模拟仿真程序,对ACC典型工况进行了仿真。仿真结果表明:模型可实现ACC的控制目的,驱动与制动可顺利切换。

To realize the aim of vehicle adaptive cruise control（ACC）, a introduced on the basis of formerly developed vehicle brake system model between the vehicle driving and braking, a vehicle longitudinal dynamic two-states model of engine was , and giving a switch criterion model was constructed. Taking santana car as an example, a simulation program was compiled to simulate the typical ACC condition of the car. The simulation results show that the suggested model can realize the ACC of the car with successful switch between driving and braking.
