基于虚拟样机技术的汽车ABS性能研究

Study on the ABS Performance Based on Virtual Proto Type Technology

在虚拟样机技术的基础上,采用基于逻辑门限值控制算法的ABS控制策略,进行了汽车ABS性能的分析和研究。首先利用ADAMS软件,建立了某轿车的14自由度虚拟样机仿真模型;再在Matlab/Simulink环境下,建立ABS制动器及其控制模型;将虚拟样机模型与ABS的控制模型相结合,从而构成研究ABS性能的联合仿真模型。最后,分别在高、低附着系数路面上分析了ABS的性能。仿真得出的结果说明了ABS联合仿真模型的可行性与有效性。该联合仿真模型的建立为加速ABS的研究和开发提供了便利和基础。

Based on the virtual proto type technology,the ABS performance was investigated with the application of logical threshold control strategy in this paper. Firstly, the virtual proto type model with 14 DOFs was built with the help of ADAMS platform. The brake system and the ABS control algorithm were developed in Matlab/Simulink. The co- simulation model was realized with the conjunction of the above models and the ABS performance could be studied. Finally, the ABS performance was obtained on the road of high and low adhesion coefficients by the simulation results. The results show that the co -simulation model is feasible and effective. The application of co - simulation technology can provide much convenience and basis for the development and research on ABS.
