The Performance of Electric Hybrid Transmission system is controlled by Electronic control unit (ECU). ECU Casing, which packages Printed circuit board (PCB) with components soldered on both sides, have to protect the PCB and components from • Thermal Damage • Dust and Water ingress • Vibrations in the vehicle • Air-Pressure fluctuations Paper enlightens Product development Architecture of ECU Casing explaining all Phases of product cultivation from processing of inputs till validation of the product. Requirement Analysis being first phase, analyses all PCB requirements, mechanical requirements related to product certification. Architecture Conceptualization being second phase, analyses layout optimization, Material Category, Manufacturing Category, Production Process, Material Grade. Design being third phase, analyses all aspects of Engineering Design, Manufacturing Design, and Feasibility Design.

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.
