Seven characteristics of automotive electronic products

The Taiwan Institute of Industrial Technology said that due to factors such as the oil crisis and global warming, energy conservation and environmental protection issues have received global attention. In order to meet the needs of subjective and objective factors such as slowing economic growth, the gradual decline in the proportion of world car ownership growth, and the arrival of an aging society, the development of the automotive industry has been jointly affected by addressing the issues of aging and transportation vulnerability, as well as the stimulation of the development of the automotive industry.
As the 3C electronics industry enters a mature period, the decline in product demand has led to a decline in gross profit margins, and the electronics industry is caught in price reduction competition. Manufacturers are seeking business opportunities for sustainable operation. The global automotive market demand has been diversified and customized, and the traditional mechanical model can no longer meet people’s desire for safe, environmentally friendly, and comfortable cars. In recent years, the technology has gradually matured, and automotive electronic products supporting electronic control technology mainly include various sensors, microcomputer controllers, video entertainment machines, satellite navigation machines
Automotive electronics can be divided into two meanings. One is the automotive electronic control device. The combination of electronic control devices and mechanical systems on vehicles is an integrated application of electromechanical systems, including engine power, sensor system control (such as image, acceleration, pressure, or temperature), electromechanical system control (such as electronic fuel injection) systems, anti-lock systems, vehicle anti-skid control, electronically controlled suspension, electronically controlled automatic transmissions, etc.); The other is an electronic device that can be used independently and has no direct relationship to the performance, safety, or control of the vehicle itself, such as satellite navigation systems, video entertainment services, and other on-board devices.
There are a wide range of automotive electronic products. The broad automotive electronic industry covers six systems, including engine/transmission system (such as electronic ignition system, automatic transmission, etc.), suspension/chassis system (including power steering wheel, chassis control, vehicle anti-skid control, etc.), body system (including lights, air conditioning, sunroof, etc.), on-board information and communication, driving safety system (such as airbag, anti-collision radar, etc.) and anti-theft protection system, It also includes power electronic components supporting six systems.
Characteristics of automotive electronic products (I)
(1) The product application environment is harsh
Compared with ordinary electronic products or even aircraft, the application environment of automotive electronics is very harsh, and the requirements for temperature, climate and other adaptability are very high. Different car manufacturers have different requirements for automotive electronics. The complexity of vehicle functional requirements increases, and a high proportion of automotive electronic products belong to sensors. Automotive products belong to global products, which need to pass strict mechanical performance or physical verification, including dust, humidity, salt, fuel additives, vibration and severe impact. Generally, sensors must be able to withstand the temperature range of – 40 ℃ – 120 ℃, and maintain a considerable degree of accuracy.
(2) Careful division of labor and product modularization
Automotive electronic products are developing in the direction of systematization and modularization of manufacturing. For example, at present, the all-in-one lights, the near/far lights, the small lights and the parking lights of automobiles are presented in a modular way, which is not only beautiful, but also provides considerable cost economy and convenience for module manufacturing and maintenance. The current popular LED lights have the characteristics of beauty, brightness, energy saving and durability. LED light products and semiconductor, electronic components Power control and other industries are carefully divided and highly relevant.
(3) Variety of products
For more than one hundred years since the development of automobile, automobile parts and components are characterized by less samples, more quantities and standardization. However, with the development and integration of communication, electronics, optoelectronics and other technologies, the proportion of automobile electronic components and products used in automobiles is increasing, and the demand for products has no common standard and presents customization characteristics. The automobile factory is based on the principle of separating the degree of price difference, and the diversity of automobile electronic products is small, the cost of automobile electronic products is high, and the compatibility is low, At the initial stage of product introduction, most of them are applied to specific advanced vehicles, and reducing the production cost of products will be the key factor for whether they can be introduced into the market in large quantities.

(4) Product validation time
Due to the close relationship between automobiles and human life safety, automotive electronic products are very different from ordinary 3C products. The operating temperature range, power consumption, size, and electromagnetic interference noise resistance of automotive electronic products are all special specifications required by various automotive manufacturers, and must meet strict standards of automotive manufacturers. They are also basic requirements for automotive electronic products.
Automotive electronic components or products usually need to go through several years of research and development and test verification. Automotive electronic products have been extended from single component products in the past to systematic products. Combined with mechanical, optical, system and electronic control, the associated technology and scope are quite extensive. The development process must be coordinated with the mechanical system or control parameters of the vehicle. Automotive electronic products have special properties and must have excellent shock resistance, weather resistance and reliability, And most of the automotive electronic products are closely related to the driving control safety, and the development cost is high and the product validation time is long. The automotive electronic products need to be tested continuously on the vehicle, tens of thousands of kilometers or even a long time of real vehicle test, so as to find problems in the continuous test process. Once problems are encountered in the test process, appropriate troubleshooting should be carried out. Repeated functional test verification and time consumption are the biggest characteristics of automotive electronic products.
(5) High entry threshold for the industry
Currently, the development of the automotive electronics industry is mostly led by world-class manufacturers, with the United States, Japan, and Germany as the main technology leaders, such as Visteon, Japan Seiji, Delphi, etc., Bosch, Siemens VDO, Dianzhuang, and even major automotive semiconductor manufacturers such as Motorola, Infineon, STM, Reiza, Toshiba, etc., all have accumulated considerable R&D experience and experience. The entry threshold for automotive electronics products is high, and in terms of systems, Taiwan manufacturers such as Huanlong Electric Appliance, Guangbao, Taida Electric Appliance, Dunyang, Comrade, Elion, and others have examples of automotive electronics applications and listings. https://forum.stoneitech.com/ (6)
Special Product Supply Chain
In order to reduce the procurement costs of direct and indirect materials, major automotive companies have accelerated the procurement pace. International procurement and even joint procurement are gradually emphasized for automotive electronic products. After the re integration and alliance merger of the international automotive industry, the global automotive supply chain will inevitably face problems such as restructuring and reshuffling. It can be predicted that the procurement focus of international automobile enterprises will shift to Chinese Mainland, Asia Pacific and other demand growth regions.
(7) Long product life cycle
Automobile is a durable and consumable product with a long service life. Generally, the development period of 3C consumer electronics products is 3 months, and the product life cycle is even 6 months. The relative life cycle of automotive electronics products is long, and the durability is harsh. The development and verification time is several years, and the product life cycle is more than 10 years.
