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.

Available in PDF, EPUB and Kindle. Book excerpt: In the last few decades, electric drives have found their place in a considerable number of diverse applications. They are successfully replacing some other traditional types of drives owing to their better performance and excellent controllability. The introduction of electric drives is in most cases also beneficial from the ecological point of view as they are not directly dependent on fossil fuels and an increasing part of electric energy they consume is generated in renewable energy sources. This book focuses on applications of electric drives that emerged only recently and/or novel aspects that appear in them. Particular attention is given to using electric drives in vehicles, aircraft, non-road mobile machinery, and HVAC systems.

Book excerpt: In spite of all the assistance offered by electronic control systems, the latest generation of passenger car chassis still relies on conventional chassis elements. With a view towards driving dynamics, this book examines these conventional elements and their interaction with mechatronic systems. First, it describes the fundamentals and design of the chassis and goes on to examine driving dynamics with a particularly practical focus. This is followed by a detailed description and explanation of the modern components. A separate section is devoted to the axles and processes for axle development. With its revised illustrations and several updates in the text and list of references, this new edition already includes a number of improvements over the first edition.

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.
