Available in PDF, EPUB and Kindle. Book excerpt: Today, the hydraulic or fluid power systems on a car, such as brakes and power steering, are strictly using fluid power. In the future, these systems may become totally electric, without any hydraulic or fluid power. Until then, the industry is using a combination of electronics and hydraulics, thus the name electrohydraulic. Through decades of research and experience, BOSCH has developed comprehensive knowledge in the field of electrohydraulics. Electrohydraulic Proportional and Control Systems conveys the state-of-the-art in electrohydraulics by presenting modern proportional control valves and servo solenoid valves, as well as open-loop and closed-loop control concepts. The operating principles of hydraulic and electronic components are described clearly and systematically in this book.Contents include: Proportional Control Valves Servo Solenoid Valves Servovalves Servo Cylinders Measurement Systems Proportional Technology Applications in Industrial Hydraulics Control Technology Applications in Industrial Hydraulics Proportional Control Valve Applications in Mobile Hydraulics Servo Solenoid Valve Applications in Mobile Hydraulics Field Bus Connection of Hydraulic Components Commissioning and Maintenance. Also includes various color pictures and charts. Published by Robert Bosch GmbH. Distributed by SAE.

This book was released on 2012-12-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Force and motion control systems of varying degrees of sophistication have shaped the lives of all individuals living in industrialized countries all over the world, and together with communication technology are largely responsible for the high standard ofliving prevalent in many communities. The brains of the vast majority of current control systems are electronic, in the shape of computers, microprocessors or programmable logic controllers (PLC), the nerves are provided by sensors, mainly electromech anical transducers, and the muscle comprises the drive system, in most cases either electric, pneumatic or hydraulic. The factors governing the choice of the most suitable drive are the nature of the application, the performance specification, size, weight, environ mental and safety constraints, with higher power levels favouring hydraulic drives. Past experience, especially in the machine tool sector, has clearly shown that, in the face of competition from electric drives, it is difficult to make a convincing case for hydraulic drives at the bottom end of the power at fractional horsepower level. A further, and frequently range, specifically overriding factor in the choice of drive is the familiarity of the system designer with a particular discipline, which can inhibit the selection of the optimum and most cost-effective solution for a given application. One of the objectives of this book is to help the electrical engineer overcome his natural reluctance to apply any other than electric drives.

Download or read book On Electrohydraulic Pressure Control for Power Steering Applications written by Alessandro Dell'Amico and published by Linköping University Electronic Press. This book was released on 2016-02-04 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with the Electrohydraulic Power Steering system for road vehicles, using electronic pressure control valves. With an ever increasing demand for safer vehicles and fewer traffic accidents, steering-related active safety functions are becoming more common in modern vehicles. Future road vehicles will also evolve towards autonomous vehicles, with several safety, environmental and financial benefits. A key component in realising such solutions is active steering. The power steering system was initially developed to ease the driver's workload by assisting in turning the wheels. This is traditionally done through a passive open-centre hydraulic system and heavy trucks must still rely on fluid power, due to the heavy work forces. Since the purpose of the original system is to control the assistive pressure, one way would be to use proportional pressure control valves. Since these are electronically controlled, active steering is possible and with closed-centre, energy efficiency can be significantly improved on. In this work, such a system is analysed in detail with the purpose of investigating the possible use of the system for Boost curve control and position control for autonomous driving. Commercially available valves are investigated since they provide an attractive solution. A model-based approach is adopted, where simulation of the system is an important tool. Another important tool is hardware-in-the-loop simulation. A test rig of an electrohydraulic power steering system, is developed. This work has shown how proportional pressure control valves can be used for Boost curve control and position control and what implications this has on a system level. As it turns out, the valves add a great deal of time lag and with the high gain from the Boost curve, this creates a control challenge. The problem can be handled by tuning the Boost gain, pressure response and damping and has been effectively shown through simulation and experiments. For position control, there is greater freedom to design the controller to fit the system. The pressure response can be made fast enough for this case and the time lag is much less critical.
