In order to achieve energy-saving and emission-reduction of automobiles, vehicle manufacturers are spared no effort to adopt various feasible electronic components, and the effectiveness of these components depends to a large extent on the semiconductor products that make up them. From a global perspective, the average semiconductor content in each car reached 262 US dollars in 2010, 305 US dollars in 2013, and 335 US dollars in 2017. In comparison, China's current average semiconductor content per car is relatively low compared to Europe, America and Japan, so the development prospects are very impressive. As a leading manufacturer dedicated to providing a wide variety of products and solutions, ON Semiconductor has designed distinctive solutions to customer system requirements in its key automotive areas to help customers improve automotive energy efficiency, reduce energy consumption, and achieve environmental Continue to develop.
Automotive market environment and its application requirements
From the perspective of the automotive market environment, the automotive application semiconductor market is huge, and the growth rate is higher than the average growth rate of the semiconductor market. In 2010, China alone produced 18.4 million vehicles. These vehicles have added many new comfort and convenience functions, as well as advanced headlight systems and LED lighting. In addition, due to the impact of hybrid vehicles and future emission regulations, hybrid and pure electric vehicles have begun to be on the development agenda.
ON Semiconductor ’s key automotive applications for the Chinese market include in-vehicle networking (IVN), automotive infotainment systems and automotive LED lighting. Power management and in-vehicle networks achieve fuel economy and emission reduction through engine control, transmission, and hybrid power; power supplies provide power to microcontrollers, infotainment systems, telematics systems, body computers, and gateways; lighting includes external (LED, HID, xenon lamp, advanced headlamp system (AFS)), interior (instrument panel, door, accent lighting). In addition, there are ASICs for power systems to implement engine control, sensors, starting AC motors, and transmission control.
ON Semiconductor's energy-saving and emission-reducing automotive solutions
ON Semiconductor provides a variety of corresponding solutions for automotive applications such as in-vehicle networks, infotainment systems, and LED lighting to help car manufacturers meet the requirements of various standards.
1) Vehicle network solution
In terms of in-vehicle networks, its advantages lie in simplifying wiring harnesses and design, reducing costs and vehicle weight; turning traditional power wiring harnesses into signal wiring harnesses, improving vehicle safety performance and reducing maintenance costs; After-sales is more convenient; it implements complex control functions and provides almost unlimited software upgrades; it is easy to form a unified open electrical platform, adapt to various vehicle models, various configuration changes, and shorten the development cycle. Therefore, at present, international car manufacturers are vigorously introducing CAN network technology. Studies have shown that after using the CAN network technology, the medium-term reduction of carbon dioxide emissions is expected to be about 2.6 g / km, and fuel economy is saved by 0.11 liters per 100 km. The evolution of vehicle network standards is shown in Figure 1.
