新型多段金属带传动汽车发动机制动控制策略研究

Study on the Control Strategy of Engine Brake of Vehicle with New Type Multi Pieces Metal Belt Drive

针对汽车在长期制动过程中发动机辅助制动能力和调速平稳性差等问题,通过将多段金属带传动引入汽车传动系,建立一种新型多段金属带式汽车传动系统数值模型,对汽车长下坡行驶工况多段金属带传动发动机制动控制策略及其可行性和对制动特性影响的规律进行研究。

For the long process of automobile engine braking capacity and speed brake assist stabil- ity poor problems, by introducing multi pieces metal belt drive into vehicle transmission system, the numerical model of a new type multi pieces metal belt vehicle transmission system is established, under the long downhill course conditions, the multi pieces metal belt drive engine brake control strategy, its feasibility and the influence law on brakin- characteristic are studied.
