One Electric Motor System for Steering Hydraulic Pump and Braking Air Pump in HEV BuS

Abstract:

The pure electric vehicles and hybrid electric vehicles are being developed and used wildly to save energy and reduce air pollution. In pure electric vehicles and hybrid electric vehicles, most of the steering hydraulic pump and braking sir pump have one electric motor to drive its pump. A new system with one electric motor for these two bumps was developed for application in pure electric vehicles（EVs） and hybrid electric vehicle ( HEVs). Comparison with conventional configuration, this new method can reduce cost and mounting space with compact size and higher energy efficiency. And the test results show that the new system can meet the requirements of HEV operation quite well.
