Automobile modularization is the domain-controlled differentiation core under the vehicle system

The direction of the future of automotive electronics is done through refactoring and customization. The industry has seen that Bosch is recommending the implementation of the distribution of the entire domain controller, which is also a strategic change in the development and deployment of global automotive OEMs. This article mainly wants to talk about the domain control differentiation under the vehicle strategy, first of all from the core point of the domain controller distribution implementation - car modularization.

Talking about car modularization

Overview of the original platform of the car: The original is to build a single Segement based on the platform.

The sales volume is actually concentrated on the platform. The bigger the car model platform, the competitive advantage is very strong.

In fact, according to the current situation, auto manufacturers face many problems. For example, China's rapidly changing market demand, the original planning, design, engineering and manufacturing can't keep up, and needs to change. In fact, in the early years, the automobile industry has begun to go in this direction, modularization to achieve strategic goals.

The goal of automotive modularity is:

• Shorten product development time and get to market quickly.

• Reduce product quality risk by reducing the number of modules.

• Enhance line flexibility to respond quickly to market changes.

• Integrate the original platform to achieve vehicle development and agglomeration, reducing the overall investment (mold, production, etc.).

• Reduce development costs and component costs by enabling component versatility across vehicle models.

• Outsourcing of non-core components, focusing on core values ​​and reducing management costs.

Take Chrysler as an example. To some extent, use fewer people as core-uniform components to supply different models.

The problem with its own double-edged sword is:

• 1. The deficiencies and recall risks caused by generalization will increase.

• 2. A lot of resources must be invested in making product design changes.

• 3. The strict requirements of auto companies for parts manufacturers.

1) The supply volume should be very flexible.

2) The supply area needs to radiate multiple areas and is supported by a strong logistics system.

3) The cost of the product should be reduced.
