Effects of introducing a cloud-based environment that provides integrated support from design to manufacturing and maintenance with Capital X, which DXs the increasingly complex design of electrical and electronic systems

With the advancement of EVs and automated driving technology, the design of electrical and electronic systems for automobiles is becoming more complex than ever before.
For example, the number of wirings, which used to be around 1,200 to 1,500 for conventional compact cars, has increased to around 1,800 with the advent of EV and hybrid vehicles and the introduction of driver assistance systems and collision prevention functions.

For large sedans, the number of wires has increased from about 2,500 to more than 3,000, and the man-hours required for design and verification work have increased significantly accordingly.
In addition, the management of vehicle specification configurations has become multifaceted, with as many as 1 million different combinations for different domestic and overseas markets, driver assistance systems, anti-collision features, and so on.
There are limits to conventional manual and Excel-based design management, and issues such as the risk of design errors, rework, and lack of coordination between departments have become apparent.

What we would like to focus on is an initiative to connect the entire process from upstream development to manufacturing and after-sales service through a consistent digital thread.
Mazda was facing a problem in the coordination of circuit design and harness design in the design of electrical and electronic systems, but by building a digital thread, Mazda was able to achieve a consistent flow of data.

Combined with vehicle configuration information, this dramatically reduces man-hours by replacing manual harness wiring work with rule-based automatic wiring.
These efforts are being deployed outside the automotive industry, including by aircraft manufacturer Airbus, as well as in agricultural machinery and space probes.

This presentation will explain the approach to streamline the increasingly complex design of electrical and electronic systems through DXing.
We also introduce the specific benefits of the solutions that support these efforts.
