2014年9月1日 · An EHPS system has the potential to dramatically increase overall system efficiency, dependent on the actual driving cycle undertaken by the truck. With the advent of increased hybridisation and hence a more robust electrical system, increased electrification of truck ancillaries are now more realistic.

2022年11月15日 · HPS和EHPS由于动力十足、价格低廉，在绝大部分商用车，尤其是重型车辆上得到广泛应用。 2020年，中国商用车汽车转向系统依旧以HPS和EHPS为主，其中EHPS占比40.1%。 不过，随着环保趋严，HPS、EHPS不仅功耗大，且存在液压油泄露问题，不符合环保要求，二者市场份额未来将逐步被EPS所取代。 汽车转向系统的发展路径： 【机械转向】 -- > 【助力转向】（液压助力转向HPS --> 电控液压助力转向EHPS --> 电动助力转向EPS）-- >【全动 …

Power Steering (EHPS) entails using typically a three-phase motor driving the hydraulic pump, rated at around 500 W. The motor only provides power on demand to pressurize an accumulator rather than the belt driven pump, which is turning constantly. On the EHPS, enhancements can be added such as sensors

The Servotwin electro-hydraulic steering system for heavy commercial vehicles is the innovative combination of the Servocom recirculating ball and nut power steering system with a steering control unit (electric motor and electronic control unit).

Infineon’s solutions for fuel efficiency, lower emissions, safety, and connectivity will revolutionize the automated driving market. Discover our different variants of electric/electro-hydraulic power steering (EPS/EHPS) solutions for 24 V commercial vehicles like trucks and busses.

2015年5月7日 · Researchers from Tsinghua University propose a new type of EHPS system suitable for heavy-duty commercial vehicles, with the purpose of reducing the power demand of an electric motor while guaranteeing sufficient power assist. The motor is only activated on-demand, which also helps to improve fuel economy.

The developed electrical hydraulic power steering (EHPS), using a high-voltage traction battery, is found to drastically reduce the consumed energy over a drive cycle by optimal operation of the pump over the driving cycle. Empirical data from a prototype HET with EHPS confirms the simulation results from Dymola. 1 Introduction

At Brogen, we offer EHPS systems with rated power ranging from 1.5 kW to 5.5 kW and more, designed for a wide range of commercial vehicles, including buses, trucks, vans, tractors, and more. We offer integrated dual-power source electro-hydraulic power steering solutions. The system employs a dual-system approach to provide steering assistance.

The electro-hydraulic power steering pump is a product developed by ECS and offers a wide range of benefits such as fuel savings, reduced CO 2 emissions, increased steering system efficiency and demand-based steering support. This makes our steering pump the perfect match for both, conventional and electric powertrains.

2015年4月14日 · In this paper, a new type of electro-hydraulic power steering (EHPS) system is described. It has two main advantages. First, it can significantly decrease the demand on the motor so that it can be used for a wider range of vehicles.
