What is the vehicle development process?

R & different automobile companies; D process is slightly different. General research and development; For normal development; D process includes 1 stage market research, 2-stage conceptual design, 3-stage engineering design, 4-stage prototype testing and 5-stage mass production.

1. Market research stage:

The research and development of a brand-new model needs hundreds of millions or even billions of dollars, which may be&; Ldquo did not conduct careful market research. Remove the water &; At present, rdquo has a special market research company in China, and auto companies will entrust them to investigate the needs, preferences and habits of domestic consumers, so as to clarify the models and market objectives, that is, the price strategy.

2. Conceptual design stage:

The concept is mainly divided into three stages: general layout, modeling design and sludge model making.

3. Engineering design stage (digital and analog construction):

After the modeling design is completed, it begins to enter the engineering design stage, which is a detailed design process of the whole vehicle, and each common component is sent to relevant departments for design and development respectively.

4. Prototype testing stage:

After the design stage is completed, it will enter the trial production stage of the prototype. The test of prototype includes two aspects: performance test and reliability test.

5. Mass production stage:

The start-up stage includes the establishment of production process chain, the arrival of various production equipment and the laying of production line. The start-up phase takes about half a year. During this period, the stamping, welding, painting and assembly production lines should be improved repeatedly. Under the condition of ensuring the production process and prototype performance, start small-scale production, further verify the reliability of products, and formally start large-scale production to ensure that the products produced in small-scale for three months have no major problems.
