A bus ride comfort adjustment

某匹配国四发动机的长轴轻型客车市场反馈有4、5档急加减速驾驶冲击强烈并有异响现象,针对此问题通过对发动机电控系统里的ASD(主动减振)功能进行优化调校,使油门控制的发动机输出扭矩平稳,降低减油门时产生的冲击和顿挫感,使车辆尽可能平稳,提高驾乘舒适性。

A matching the country four engine the long axis of the light-duty bus market feedback 4,5 files urgent acceleration and deceleration driving shocks are strong and have a stable phenomenon of abnormal noise. To solve this problem by optimal adjustable fimction of ASD（active vibration reduction） in the engine electronic control system, the control of accelerator engine output torque, reduce the throttle reduces shock and frustration feeling, make the vehicle as smooth as possible, improve the driving comfort.
