Motorization in vehicles is expanding rapidly for fuel efficiency, customer comfort, convenience, and safety features. These
new electric loads represent an increase in the required electric power. This has generated interest in new, higher power
systems such as the 42V Power Net. The electro-hydraulic power steering (EHPS) system is one of these systems. This paper
presents the development of the electric motor-driven pump unit for the EHPS system using a 42V power-Net. The interior type
permanent magnet synchronous motor (IPMSM) can be applied to this system with more power density per volume for compactness
of the EHPS. In order to improve the system, the IPMSM and its control method was optimized for improved torque characteristics
and electric power consumption. The performances of both the pump unit and the IPMSM have been verified by experimental results.
Finally, all in one type the electric motor-driven pump unit are developed from the experiment verification. 相似文献

This paper focuses on fuel economy improvement according to the type of power steering system. Usually, a conventional power
steering system is directly driven by the crankshaft of the engine with a belt, known as HPS (hydraulic power steering). However,
there is some inefficiency with this system at high engine speeds. To improve this inefficiency, automobile makers have developed
two power steering systems: EHPS (electro-hydraulic power steering) and MDPS (motor-driven power steering) or EPS (electric
powered steering). However, there has been insufficient study of effects of the type of power steering system on fuel economy.
In this paper, the effect of the type of power steering system on fuel economy is studied experimentally, and calculations
of the effect on vehicle fuel economy are presenting using computer simulation with AVL cruise software. The results demonstrate
that a 1% vehicle fuel economy improvement can be achieved in a vehicle with an electro-hydraulic power steering system compared
to a vehicle with a hydraulic power steering system. In addition, a 1.7% vehicle fuel economy improvement can be achieved
using a full electric power steering system in a FTP-75 driving cycle. These results could be used to choose a power steering
system. 相似文献

This paper pursues two objectives: Firstly, to review the state-of-the-art of general purpose vehicle system dynamics software and secondly, to describe two representatives, the program MEDYNA and the program NEWEUL. The general modeling requirements for vehicle dynamics software, the multibody system approach and a comparative discussion of multibody software are given. The two programs NEWEUL and MEDYNA are described with respect to modeling options, computational methods, software engineering as well as their interfaces to other software. The applicability of these programs is demonstrated on two selected examples, one from road vehicle problems and the other from wheel/rail dynamics. It is concluded that general purpose software based on multibody formalisms will play the same role for mechanical systems, especially vehicle systems, as finite element methods play for elastic structures. 相似文献
