Über dieses Buch

This book offers first a short introduction to advanced supervision, fault detection and diagnosis methods. It then describes model-based methods of fault detection and diagnosis for the main components of gasoline and diesel engines, such as the intake system, fuel supply, fuel injection, combustion process, turbocharger, exhaust system and exhaust gas aftertreatment. Additionally, model-based fault diagnosis of electrical motors, electric, pneumatic and hydraulic actuators and fault-tolerant systems is treated. In general series production sensors are used. It includes abundant experimental results showing the detection and diagnosis quality of implemented faults.

Written for automotive engineers in practice, it is also of interest to graduate students of mechanical and electrical engineering and computer science.

Chapter 1. Introduction
Abstract
The increasing electrification and electronification is a dominant feature of modern automotive developments. This is demonstrated by an increasing part of electrics/electronics (E/E) of the manufacturing costs from about 20 % in 1995 to 35 % in 2014. The electrics comprise primarily the electrical energy flows to the consumers through the energy board net.

Supervision, Fault Detection and Diagnosis Methods

Frontmatter
Chapter 2. Supervision, fault-detection and fault-diagnosis methods – a short introduction
Abstract
Fault detection and fault diagnosis belong to the general area of supervision or condition monitoring of technical processes. The task is to indicate undesired or not permitted states and to take appropriate actions to avoid damage, accidents or environmental pollution. This includes states of the powertrain and the chassis which are dangerous (e.g. spinning vehicle), not economic (e.g. high fuel consumption or high wear and tear) or not ecologic (e.g. too high emissions).

Diagnosis of Internal Combustion Engines

Frontmatter
Chapter 3. On the control and diagnosis of internal combustion engines
Zusammenfassung
As the supervision and diagnosis functions of internal combustion engines are strongly connected with the control functions, this chapter briefly presents the basic control tasks and some control functions. This is followed by a short discussion of present on-board diagnosis (OBD) requirements and realized approaches. Because of the complexity of the sensors, actuators and ECU control functions, the controloriented structure of the engines from Isermann (2014) is used, which also helps to structure the supervision and diagnosis functions.

Chapter 4. Diagnosis of gasoline engines
Abstract
The model-based approach for the fault diagnosis of gasoline engines follows a modular structure. The engine is divided in engine parts and their components, actuators, standard sensors and additional sensors.
Rolf Isermann
Chapter 5. Diagnosis of diesel engines
Abstract
In order to develop advanced fault-detection and diagnosis systems for diesel engines a modular structure is used, which is based on the available input and output signals from the ECU and comprises the actuators and engine components and their sensors, compare Tables 3.3.1 to 3.3.4 and Fig. 3.1.7. Then, so called detection modules are defined which allow the fault detection of the interacting components by using their signal readings.

Diagnosis of Electric Drives, Motors and Actuators

Frontmatter
Chapter 6. Diagnosis of electric motors
Zusammenfassung
The increasing electrification of the powertrain, the chassis and the body means a strong enlargement of electric drives and electric actuators, as discussed in Chap. 1. Important electric motors at the internal combustion engine are, for example, the auxiliary drives, like the electrical generator, starter and cooling fan and several electric actuators, like for the electrical throttle, the exhaust-gas recirculation valve and the variable geometry turbocharger.
Rolf Isermann
Chapter 7. Diagnosis of actuators
Abstract
Actuators usually transform low-powered manipulated variables (e.g. analog voltages 0…12V, applied DC currents 0…20 mA or 4…20 mA, pneumatic pressures 0.2…1 or 1…8 bar, or hydraulic pressures 0…150 bar) into process (engine) input variables of a much higher power level. Frequently the process input variable is a flow of energy or matter, or a force or torque.
Rolf Isermann

Fault-Tolerant Systems

Frontmatter
Chapter 8. Fault-tolerant components
Abstract
Partially and highly automated driving automobiles are characterized by automatic controlled longitudinal and lateral movement and at least a reduced, permanent acting driver. This requires an increased supervision of all active systems and a faulttolerant design of the safety-relevant components of the chassis and the powertrain.
Rolf Isermann

Chapter 9. Terminology in fault detection and diagnosis
Abstract
The following definitions are the result of a coordinated action within the IFAC Technical Committee SAFEPROCESS, published in Isermann and Ballé (1997). Some basic definitions can also be found in IFIP (1983), Omdahl (1988) and in German standards like DIN and VDI/VDE-Richtlinien, see references at the end of this section and Isermann (2006).
