无级变速车辆起步液力变矩器分段滑差控制
|
摘要
本文中针对无级变速器车辆液力变矩器起步过程存在的加速性能差、发动机转速偏高和转速波动大的问题,提出了一种基于发动机恒转速控制的闭锁离合器起步滑差分段控制策略,并基于Amesim和MATLAB/Simulink搭建整车联合仿真平台,进行验证。仿真结果表明,在50%油门开度下,本文中提出的控制策略可将液力变矩器的闭锁时间提前1.2s左右,同时也可将50%油门开度起步阶段的燃油消耗节省5.385%,为进一步挖掘动力传动系统节油潜力提供了新的方法。
To solve the problems of slow acceleration response, high engine speed and engine speed fluctuations in the starting process of CVT vehicle torque converter, a segmented slip control strategy of lock-up clutch at starting conditions is brought forward based on constant engine speed control and a vehicle co-simulation platform based on Amesim and Matlab/Simulink is established to verify the proposed strategy. The simulation results show that the proposed control strategy can advance the locking time of the torque converter by about 1.2 s and reduce the fuel consumption by 5.385% at the start stage of 50% throttle opening. The proposed strategy provides a new method for further tapping the fuel-efficient potential of the powertrain.
