As a significant control component of vehicles, automatic transmissions should have failure protection function. The failure protection function partly is determined by the hydraulic control system. However traditional design could not cover all of failures, and there is no general design method. A design method is proposed for designing the shift control oil circuit of the hydraulic control system with the failure protection function. . The design method is applied to optimize the hydraulic control system of a six-speed automatic transmission. The function of the optimized hydraulic control system is confirmed by the dynamic simulation. The results show that the design method can simplify the hydraulic control system without losing any original functions. The proposed design method is proved to be suitable for all kinds of hydraulic control systems of automatic transmissions.

The objective of this research is to continue development of a system for measuring in-cylinder pressure using a low cost, non-intrusive valve movement sensor as detailed in SAE paper 2009-01-0245. This research should enable the use of cylinder pressure information to be extended into smaller in-service internal combustion engines particularly when “closed loop” control is required to control combustion. This update details the latest development results for this cylinder pressure concept. The conclusions drawn in the original paper are that a system for measuring in-cylinder pressure using a valve movement sensor were possible at the required accuracy and had the potential to be lower cost than the current best technology. This update strengths these conclusions with motoring and firing test results using the signal output from a low cost Hall-effect sensor. The firing results are then used to calculate key combustion metrics for engine control.

Based on their 25 world-wide years’ experience in refining and fuel formulation using Near Infrared technology, the SP3H team has developed an innovative and miniaturized optical fuel quality sensor (SAE 2007-01-1830, SAE 2008-01-2451). The sensor output is based on an HCP matrix (HydroCarbon Profilers) and provides information on the fine chemistry of fuels such as aromatics, olefins, isoparaffins and oxygenates content and information related to the lengths of the Carbon-Carbon bonds Chain. According to this information, the sensor can also provide : - an accurate information on biodiesel content of diesel/biodiesel mixtures, - the rate and the type of oxygenates used in different mixtures of binary and ternary blends of methanol, ethanol and gasoline for emerging market. This paper presents the results of the latest developments of the sensor.

The paper will outline development and test methodologies applied to an intelligent mechatronic actuator. This actuator technology has similar controls architecture and communication interfaces as other powertrain control modules, and in addition, has similar calibration and application optimization requirements. In lieu of leveraging the typically high investment costs associated with the more conventional commercial off-the-shelf (COTS) toolchains for calibration and optimization, this paper will highlight activities to provide a more cost-effective development architecture that offers flexibility, extensibility and customization required to enable automated/unattended testing, as well as mechanisms to acquire, evaluate, and react to actuator performance test results in order to pursue targeted actuator performance optimization. In addition to explaining the elements of the development infrastructure, a roadmap for potential avenues for future improvements will be discussed.

Air intake filter is generally designed to meet the different requirement of engine and vehicle like intake air filtration, air flow rate, engine life, NVH, emission and service requirement. The pressure drop across the air filter increases due to accumulation of dust, metal particles, organic particle etc. during the driving of the vehicle. The service life of the air filter is recommended by the vehicle manufacturer in terms of km covered. The type of dust and its accumulation in the air filter also depend upon traffic condition and environmental condition which may differ from country to country and from region to region especially in Asian countries. Hence, the mileage based service interval of intake air filter may not be optimum for different region to keep the optimum performance of the engine and vehicle for a longer period. An attempt has been made to monitor the condition of the intake air filter in the vehicle.

In recent years, the request for the air flow sensor with the detectability function of reverse-air-flow has increased to monitor the state of the engine intake manifold air because of responding to the enhancement of exhaust emission regulation and improving the fuel efficiency. According to the request, such air flow sensor has been realized and commercialized by using MEMS (Micro Electro Mechanical Systems) technology: formation of a membrane and heaters to the silicon semiconductor chip. In addition to the detectability function of reverse flow, air flow sensors are required to be highly precise, reliable and strong. This paper describes the newly developed MEMS-based air flow sensor, with those properties including the reverse-flow detectability, which is expected to become a key device for vehicle engine control.

Over the last decades, the industry has provided a steady improvement in the safety of automobiles. Advances in modern electronics have accelerated the number and features of safety systems. Semiconductor devices, sensors, actuators and computer controlled systems with complex software are integral to these system designs. This increasing complexity drives the need for a systematic process for safety systems development and engineering to achieve their full operation potential. ISO-26262 "Road vehicles — Functional Safety" provides appropriate standardized requirements, processes and an automotive-specific risk-based approach to determine integrity levels, also known as Automotive Safety Integrity Levels or ASILs. ASILs are used to specify applicable requirements of the ISO-26262 standard so as to avoid unreasonable residual risk; Smart integrated sensors, such as angular position sensors, are used extensively in automotive safety-critical applications.

In the development and optimization of internal combustion engines, simulation tools gain in importance as they are a more cost effective solution in the optimization process than just relying on experimental optimization. An important sub-model in these simulation tools is the heat transfer model that predicts the heat loss from the combustion gases to the chamber walls. This heat transfer has a large effect on the efficiency, emissions and power output. Accurate measurements of the heat flux are essential to build an adequate heat transfer model. These measurements are required to fully understand the heat transfer phenomena in a combustion chamber. The Thin Film Gauge heat flux sensor has been proven to be an adequate sensor for this purpose. This paper reports on the calibration of the TFG sensor for measurements in internal combustion engines. A TFG sensor consists of a platinum thin film which serves as a resistance temperature detector on an insulating substrate (ceramic).

The introduction of the EURO VIC and EPA MY16+ emission regulations for commercial vehicles has brought an increase in the complexity of exhaust gas aftertreatment systems and its On-Board Diagnostics (OBD). Hence, the challenge in the development of OBD algorithms is to keep the calibration effort low and achieve a high robustness against component variation and long term effects, e.g. aging or sensor drifts, at the same time. This implicates approaches without additional sensors or hardware. IAV has developed algorithms meeting these challenges for SCR efficiency monitoring and DPF efficiency monitoring. The SCR efficiency monitoring algorithm is based on a stochastic filter. It removes the outliers in the data depending on stochastic moments like mean-value and standard deviation of a Gaussian distribution. The advantage of the algorithm is an increased robustness and a low calibration effort due to a limited number of release conditions.
