In today’s update, I would like to discuss about the preparation and how you can layout its foundation for those of you who are planning to get involve or already started in EV business, to be ready for new changes and challenges of electrical engineering systems development for autonomous vehicles. The topics for today will cover 3 systematical strategies of how you can plan out for your company business for this field;

1) E/E Systems in Model Based Systems Engineering

2) E/E Systems for Autonomous’ Architecture Design

3) E/E Systems Development Flow Integration

Let’s investigate industry challenge and complexity in architecture evolution towards autonomous vehicles design.

According to Designed around You information, we can bravely say that the architecture has significantly changed yearly towards autonomous vehicle designs and mostly developed for its own model which is not scalable and reusable. This will cause a major time consumption for production and service. The system in new car required higher electrical power output, now it is changed from 12 V to 48 V due to complex dependencies (new devices, systems, and connections)

Production Development is changing across all industries

1) E/E Systems in Model Based Systems Engineering - PLM, ALM and Simulation & Test – Continuous Engineering

Optimization – Scaling to the full Vehicle

Capital E/E Systems Integration in the MBSE Digital Thread – Continuous Closed-Loop Systems Engineering Context

2) E/E Systems for Autonomous’ Architecture Design
Capital E/E Systems & Architecture Development – Three major concerns need to focus on

Automotive Environment of the Future Autonomous Vehicles – Continuous integration of hardware & software lifecycle

Capital E/E Systems Integration – Electrical Engineering Domain Lifecycle of a network signal

Capital E/E Systems Integration in the MBSE Digital Thread – Software & Network Engineering Lifecycle of a network signal

Capital E/E Systems Integration in the MBSE Digital Thread – End-2-End Traceability across the E/E System Integration

3) E/E Systems Development Flow Integration
Integration Flow
Establishing an Architecture-driven E/E Systems Development Flow – All abstractions & domains natively connected and integrated into ALM & PLM

E/E Systems Development delivers the means to bring sophisticated AV features & products to life

All encompassing advancement of E/E Frameworks, counting electrical, networks and software streams is crucial. These tasks, empowered by a useful safety empowered forms are center to any complex framework plan.

Creating transparency between silos, blurring domain boundaries across the E/E Life Cycle

Capital shapes boundaries across engineering, manufacturing and service to progress quality and quicken product development.

Expansion of Siemens’ Capital portfolio brings new levels of integration for holistic engineering

Section of Siemens Xcelerator portfolio, Capital’s electrical legacy is amplified into an unrivaled portfolio to assist change framework plan for complex items at first focusing on, focusing on car, aviation and adjoining markets.
