摘要
为提高自动挡车型的驾驶性能,以应对舒适性要求日益严格的汽车消费市场,文章设计了一种基于扭矩模型的汽油机断油逻辑,通过使用此逻辑合理配置标定参数,可以实现断油过程以及断油后恢复供油过程的扭矩平滑过渡,进而可减缓断油引起的传动系扭振,达到优化驾驶舒适性的目的。该控制基于发动机管理系统实现。
To improving the performance of automatic-shift cars driving in response to the comfort requirements of increasingly stringent auto market,this paper designs a model based on torque of gasoline engine oil cut-off logic.It can realize the smooth transition of torque during oil break and the recovery of oil supply after oil break,thus slowing down the torsional vibration of transmission system caused by oil break,in order to optimize driving comfort.The control is based on the engine management system.
