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: Purdue University has played a leading role in providing the engineers who designed, built, tested, and flew the many aircraft and spacecraft that so changed human progress during the 20th century. It is estimated that Purdue has awarded 6% of all BS degrees in aerospace engineering, and 7% of all PhDs in the United States during the past 65 years. The University's alumni have led significant advances in research and development of aerospace technology, have headed major aerospace corporations and government agencies, and have established an amazing record for exploration of space. More than one third of all US manned space flights have had at least one crew member who was a Purdue engineering graduate (including the first and last men to step foot on the moon). The School of Aeronautics & Astronautics was founded as a separate school within the College of Engineering at Purdue University in 1945. The first edition of this book was published in 1995, at the time of the school's 50th anniversary. This corrected and expanded second edition brings the school's illustrious history up to date, and looks to Purdue's future in the sky and in space.

This book was released on 2019-04-15 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Essay from the year 2018 in the subject Engineering - Automotive Engineering, grade: 1,3, Ingolstadt University of Applied Sciences, language: English, abstract: This paper analyses ESP/ESC in vehicles. Electronic stability control (=ESC) as active safety system is getting more and more common in todays vehicles. First established in 1995 by Bosch and Daimler under the well known brand ESP it has obviously prevented many accidents all around the world. Many studies show that the main target of ESC which is preventing fatal side crashes into the less resistant side components of vehicles was reached. It shows that average skilled drivers are just not able to perform the necessary measures to escape riskful lateral driving conditions on their own. This evidence and the fact that ESC is rather cheap to implement into an existing vehicle structure due to the usage of Antilock-System (=ABS) and Anti Slip Control (=ASC) hardware components led to the fact that many states passed laws which makes an ESC system mandatory in every vehicle sold in their territory. ESC is based on fundamental control engineering, vehicle dynamics, fluidmechanics as well as the combination of different energy domains (electric, mechanic, hydraulic) and is using the vehicle brakes as well as reducing engine power to stabilize vehicle behaviour in critical driving situations like over- and understeering. These circumstances can be measured, predicted and processed by several sensors and the control unit itself in order to initiate the appropriate actor reactions. Parameters that are necessary for the control algorithm but are hardly measurable with sensors like the effective friction coeffient between road and tire need to be calculated via other auxiliary variables e.g. rotational speeds. Since ESC is always in it’s overall component structure the same but in its specific reaction (=control) and modeling differing due to the desired driving behaviour of a particular manufacturer, tests need to be performed to prove the stabilizing effectiveness of its output signals which are represented as brake torques and reduction of engine power. In order to perform these tests engineers need to understand the systems general behaviour (=transfer function) which makes it then possible to design different test scenarios stimulating the system, determining crucial measurement variables and analyzing their results. There are many tests concerning vehicle stability established in the industry already. These verifications can be virtually and/or physically conducted.
