摘要：

为降低重型车辆液压转向系统 (HPS) 的能耗，改善高速工况转向驾驶员路感、提出一种节能
型电磁离合器电控液压转向系统(E-ECHPS)，该系统采用电磁离合器控制转向泵转矩和转速。运用有
限元分析法，建立电磁离合器主、副电机仿真模型，研究主、副电机的动力特性；研究电磁离合器功
率输入输出的关系，分析该E-ECHPS 的节能性；对E-ECHPS 转向工况下的助力性能和直行工况下的
能耗进行了仿真分析。结果表明：在转向工况，电磁离合器的输出转矩随车速增大而减小；在直行工况，
在车速为10、40、80 km/h 的时段内，该E-ECHPS 的总能耗相比HPS 减少71%。该E-ECHPS 可实现
随车速可变的助力特性，并具有明显优于HPS 的节能性。

Abstract:

An energy-saving Electromagnetic clutch Electronically Controlled Hydraulic Power Steering System
(E-ECHPS) was proposed with an electromagnetic clutch to control the steering pump for reducing the energy
consumption of hydraulic power steering system (HPS) and improve driver’s feel on high speed road for heavyduty
vehicles. FEA (finite-element analysis) models were established to investigate the dynamical characteristic
curves of main and vice motor in electromagnetic clutch. Based on power changes in electromagnetic clutch,
an energy-saving of the E-ECHPS was analyzed. Energy dissipation and assist characteristic of the E-ECHPS
under steering situation and straight road condition were simulated. The results show that electromagnetic
clutch torque decreases with vehicle speeds increase under steering situation; the E-ECHPS saves energy
consumption more than 71% compared to HPS in the time interval with the vehicle speeds of 10, 40, 80 km/h
under straight road condition. The results indicate that the E-ECHPS can realize the variable assist characteristic
and have significantly better energy efficiency than that of the HPS.

Key words: heavy-duty vehicles, Electronically Controlled Hydraulic Power Steering (E-ECHPS) system, electromagnetic clutch, energy saving, assist characteristic
