The ever increasing requirements for vehicle performance, fuel economy and emission have been driving the development and adoption of various types of hybrid powertrains. Hybrid powertrains are of many different configurations and may include such components as hybrid controller, engine, transmission, generator, battery and battery management system, ultracapacitor, traction motor and inverter etc. A Hardware-in-the loop (HiL) testing solution that is flexible and can be used for different types of hybrid powertrain configurations is greatly desired. This paper describes the design and implementation of a HiL testing system that can be used for testing various hybrid powertrain configurations and as few or as many of the powertrain components. The system is centered on a high performance real time controller that runs necessary driver, powertrain, driveline, and vehicle models.

ARP1533C
SAE Aerospace Recommended Practice ARP1533 is a procedure for the analysis and evaluation of the measured composition of the exhaust gas from aircraft engines. Measurements of carbon monoxide, carbon dioxide, total hydrocarbon, and the oxides of nitrogen are used to deduce emission indices, fuel-air ratio, combustion efficiency, and exhaust gas thermodynamic properties. The emission indices (EI) are the parameters of critical interest to the engine developers and the atmospheric emissions regulatory agencies because they relate engine performance to environmental impact. While this procedure is intended to guide the analysis and evaluation of the emissions from aircraft gas turbine engines, the methodology may be applied to the analysis of the exhaust products of any hydrocarbon/air combustor.

ARD6888
The purpose of this document is to specify the functional requirements for a miniature connector to be used for health monitoring purposes on aircrafts (including harsh environment such as the powerplant). It is actually a family of miniature connectors that is specified in this document for various uses (e.g. pin counts) and environments. This specification will be used by the SAE connector committee to work on a dedicated connector standard.

ARP6320
This Aerospace Recommended Practice (ARP) consists of methodologies for the measurement of non-volatile particulate matter (nvPM) emissions at the exit plane of aircraft gas turbine engines. The methods describe means of sampling and measuring particle mass concentration, particle number concentration and reporting of emissions indices through the use of an appropriate sampling system and instrumentation that goes beyond the measurements of visible obscuration as described in ARP 1179 for Smoke Number (SN).

Model-Based Design allows early verification of embedded controls during development such that errors can be detected and fixed when the cost of correction is comparatively lower. With the advent of electrified powertrain applications, design complexity and amount of new content are driving engineers to build a comprehensive model-based verification workflow. However, due to the impact on many aspects of the development process and different engineering roles, such model-based verification can be challenging to create and implement. Companies doing Rapid Prototyping (RP) often try to extend RP directly into a production verification workflow by incrementally improving individual verification activity as oppose to take a holistic view of the entire process.

In response to demand for increased engine fuel economy and lower emissions, engine hardware must be re-designed and improved frequently. Engine designs also need to be adapted for electrified powertrain applications. Engine designers use high fidelity engine models to simulate and assess the changes to engine hardware design. To assess the impact of hardware changes correctly, the engine control software calibration for variables such as spark advance, throttle position, air-fuel ratio, and turbocharger wastegate position must be re-adjusted so that the benefits of hardware changes can be realized. Unfortunately the re-calibration step in the design process currently requires approximately 2 days of expert manual labor, so re-calibration is rarely done for every engine hardware design change in simulation.

The global trend to reduce CO2 emission in automotive industry is unchangeable. And the way to reach different level of CO2 reduction has various approach, from tradition powertrain enhancement for gasoline & diesel to new energy solution like electrification (Stop-Start, Hybrid and pure EV),CNG, fuel cell, etc. Semiconductors were, are and will be the key innovative factors to enable the change. The presentation will give you the overview on Fuel Efficient Powertrains in Traditional and in New Energy Vehicles and this will help the automotive industry to select the semiconductors to fulfill the targeted fuel efficiency which cover 12V/48V of low voltage board nets and xEV of high voltage board nets.
