Book excerpt: Automotive Vehicle Strategies and ECM Modes(Diagnostic Strategies of Modern Automotive Systems)By Mandy ConcepcionThis book is divided into two sections, “Vehicle Operational Strategies”, which detail what's needed for and engine to start. In other words, this section concentrates on the signals needed for a particular manufacturer to make the engine run. These signal strategies are true regardless of the system and the section simply zeros in on the actual signal, whether it's a distributor, DIS, COP, etc. The second section is the "ECM operational modes" and goes into details on why and how the ECM does what it needs to do to run the engine. In other words, this section has to do with the behavior of the ECM according to outside conditions.VEHICLE OPERATIONAL STRATEGIESThis section is designed to serve as a functional guide to some of the more difficult to diagnose faults. It basically came about from the trial and error experimentation with different systems, during the diagnostic process. It is not a study section per se, but will definitelyenlighten the technician as to the logics of different systems on the market today. Hopefully, it will serve to pinpoint the source of an actual problem.ECM OPERATIONAL MODES In this section, we'll take a look at automotive OPERATIONAL MODES. The section deals with the specifics of internal ECM programming strategies. The knowledge gained here will aide the modern technician is deciphering why is the ECM functioning in a specific way. This section, as in other parts of this book, helps to answer the technician's diagnostic basic question “What is the ECM seeing, that's causing it to do what it does?”Table of ContentsVEHICLE OPERATIONAL STRATEGIES- HONDA IGNITION & INJECTION STRATEGY- MAZDA IGNITION STRATEGY- MAZDA EEC IV IGNITION STRATEGY- MITSUBISHI/HYUNDAI IGNITION STRATEGY- NISSAN IGNITION STRATEGY- NISSAN COP IGNITION STRATEGY- TOYOTA IGNITION STRATEGYECM OPERATIONAL MODES• CRANKING ENRICHMENT MODE• ENGINE WARM-UP MODE• OPEN-LOOP MODE• CLOSE-LOOP MODE• ACCELERATION ENRICHMENT MODE• DECELERATION ENLEANMENT MODE• IDLE SPEED CONTROL MODE• LOW VOLTAGE CORRECTION MODE• CLEAR FLOOD MODE• SELECTIVE FUEL INJECTOR CUT-OFF MODE• LIMP-HOME MODE• EXHAUST VARIABLE VALVE TIMING/EGR CONTROL MODE

Available in PDF, EPUB and Kindle. Book excerpt: Automotive Scan Tool PID Diagnostics (Diagnostics Strategies of Modern Automotive Systems ) By Mandy Concepcion In this section, the different techniques of scan tool parameter (PID) analysis will be exposed. Techniques involving PID analysis are quickly catching on, due to their speed and accuracy. By properly analyzing the different scanner PIDs, the technician can arrive at the source of the problem much faster and accurately. These procedures give rise to the new term “driver seat diagnostics”, since most of the preliminary diagnostic work is done through the scanner. However, these techniques will in no way replace the final manual tests that are a part of every diagnostic path. They are simply geared to point the technician in the right direction.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper, the need to develop a control strategy and test apparatus for nextgeneration hybrid vehicles was realized. The complexity of today's and future hybridvehicles necessitates the need for an equally advanced method of control that can extractthe optimal fuel economy from the system as a whole. A review of existing hybrid vehicle control strategies was performed. Overall, muchresearch has been done on the optimization of series and parallel type vehicles, butvirtually no information was found on the optimal use of advanced powersplit drivetrains. However, the control strategy concepts explored in the literature are useful, and can beextended to complex architectures like the General Motors Two-Mode design. Theequivalent consumption minimization strategy (ECMS) method developed by Rizzoni etal at the Ohio State University has proven to be a well developed control strategy that hasseen much progress over the last decade. Although it has been only demonstrated onparallel-type vehicles, it was chosen as the basis for the control strategy methodology. An in-depth analysis on the Two-Mode transmission operation was performed. Thefundamental equations for each of its range states were derived for future use indeveloping a plant model, and for use in control strategy development. The torque andspeed capabilities of each of its modes and gears were analysed. A detailed plant model was created to form a virtual test bed for control strategy development purposes. The models use empirical data provided by manufactures, which ensures a reasonable level of accuracy in portraying component constraints and efficiencies. Building on the ECMS, a similar hybrid vehicle control strategy was developed forTwo-Mode transmission based vehicles. It was modified to handle two degrees offreedom as required by the system. Its objective is to constantly minimize the totalequivalent power use in the system which is defined as the sum of the chemical power inthe fuel and the power used by the battery multiplied by an equivalency factor. Overall, the control strategy provides a strong basis for the optimal control of nextgenerationhybrid vehicles incorporating powersplit transmissions. It is suggested thatfurther research be explored in combining rule-based control methods with the developedoptimization based method since rule-based methods can add the stability required forenhanced drivability.

Available in PDF, EPUB and Kindle. Book excerpt: Integrated Vehicle Health Management (IVHM) is the unified capability of a system of systems (SoS) to assess the current or future state of the member system health, and integrate it within a framework of available resources and operational demand. As systems complexities have increased, so have system support costs, driven by more frequent and often enigmatic subsystem failures. IVHM strategies can be used to mitigate these issues by taking a Systems of Systems view. Combined with advanced decision support methods, this approach can be used to more effectively predict, isolate, schedule, and repair failed subsystems, reducing platform support costs and minimizing platform down time. Integrated Vehicle Health Management- System of Systems Integration brings together ten seminal SAE technical papers addressing the challenges and solutions to maintaining highly complex vehicles. The strategy requires that the IVHM system must provide actionable decision support to operators and maintainers, informing platform operational capabilities and maintenance procedures. The goal is to prevent a given component from degrading to the point of failure or predictable impending failure. Specifications should also reflect a common means for communicating this information to other health- ready IVHM system components.

Download or read book Automotive Sensory Systems written by C. Nwagboso and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapidly growing need for mobility has brought with it a major challenge for improvement in the operation and utilization of automotive systems. The economical, environmental and safety constraints imposed by the increase in the number of road vehicles and subsequent government policies also require substantial product development through the application of infor mation technology. This involves the enhancement of vehicle informatics and telematic systems with additional sensors and systems. The advance in the design and development of automotive sensory systems is so rapid that there is urgent need for the experts involved in the technology to work together to provide a reference book for the engineer of today and tomorrow. This motivated me to spend two years researching the topics and the basis on which such a book should be written. The result is the present compilation of the work of international experts on the state-of-the-art in the field of automotive sensory systems. Thus, a unique collection has been created for the reference of all those concerned with, or interested in, the design and development of modern, safe and intelligent vehicles. Although this book is intended for engineers, managers, scientists, academicians and policy makers, students should also find it valuable. To meet the requirements of students the basics are explained in simple terms; however, it is hoped that others will appreciate this approach, since most of us are well aware that gaps remain in our knowledge of the elements of our profession.
