At present, the proportion of original electrical and electronic products used in automobiles to total vehicle costs has increased from 25% to 40%. In the future, this proportion will definitely increase. Statistics show that the market is showing an annual growth rate of 7%. Take the telematics system as an example, its market will reach 20 billion US dollars.
What is automotive electronics?
Automotive electronics can be divided into visible and non-visible parts, in-vehicle devices are visible parts and automotive electronic controllers are non-visible parts. From the point of view of use, it can be divided into automotive electronics, power control systems, safety control systems, body control systems, driving control systems, and information systems.
Power control system: including engine management control system, power steering, AT control and ACC
Safety control system: including airbags, ABS/ASR and SAFE-BY-WIRE
Body control system: including body control of switch control, lighting control, anti-theft system, door lock control, window control, wiper, etc.
Travel control system: including instrumentation, air conditioning and chassis control system
Information system: including entertainment, mobile communications, GPS navigation and information processing systems
As we all know, the car consists of four parts, namely the body, chassis, engine, electronic system, and the car electronics are basically contained in the body, chassis and engine. From the comfort, safety and entertainment of the car, all aspects of the car need to adjust the role of automotive electronics. Among the cars of different grades and technologies, the proportion of automotive electronics in the cost of complete vehicles is as follows.
In general, automotive electronics is a combination of electronic technology, automotive technology, information technology, computer technology and network technology, including the basic technology layer, electronic control system layer and human-car environment interaction layer, and has experienced discrete electronic elements. There are three development stages of device control, component independent control, and intelligent, networked integrated control applications.
In the wave of global semiconductor acquisitions, automotive electronics companies have become the most sought-after toon. In 2016, there were many acquisitions related to automotive electronics. NavInfo's 3.875 billion yuan acquired Jiefa Technology to fill the key link of unmanned driving. Qualcomm's more than 30 billion US dollars to acquire Dutch NXP Semiconductors became the biggest acquisition. Samsung acquired Kazakhstan. Man is also interested in automotive electronics. Although Siemens' acquisition of Mentor is stupid, it is analyzed that it has a far-reaching relationship with automotive electronics.
Today, the rapid development of the automotive electronics industry, what are the key words of automotive electronics technology?
Keyword 1: Autopilot
Automated driving is sweeping the global auto industry with strong momentum. Many automakers, auto parts companies, IT communication companies and other forces are involved in autonomous driving and participate in R&D and manufacturing. Unmanned driving will solve the problems in urban development such as congestion and parking difficulties. Unmanned technology can also be used in logistics, shared travel and other fields, with high social and economic benefits.
Unmanned driving is not simply a competition between enterprises. Now it has risen to the level of national strategy. The "national competition" for the leadership of the unmanned industry has been fully opened. Yes, this is a battle that is related to national competitiveness. From sensor supply to software technology integration to hardware creation, autonomous driving is becoming a big cake in the automotive industry chain.
The US Department of Transportation released the first draft of a driverless car regulation issued by a sovereign state on the earth; the Japanese government’s strategic goal is to achieve complete unmanned driving at the L4 level at the 2020 Tokyo Olympics, and the Japanese government hopes to rely on The strategic opportunity of “driving people†has regained its leading position in the Asian region; the Chinese government has released a roadmap for driverless technology in Shanghai, and plans to achieve 15% of new cars with unmanned capabilities by 2025. The German Ministry of Transport, Bavaria and Audi jointly launched the driverless program.
Since Tesla’s driverless car accident, unmanned driving has stood on the cusp of the cusp. Can drone really replace people’s driving? I believe that this is definitely inevitable, but it takes time to wait for the technology to mature. Now all companies that develop unmanned vehicles are actively promoting the development of AI systems. Yes, AI will make cars learn, think, and judge.
In 2020, many people in the industry regard it as a watershed in the development of autonomous driving. In 2020, the automatic driving technology will be more mature and perfect, and some highly self-driving vehicles will appear. According to Morgan Stanley, by 2030, the size of the driverless industry will reach 6 trillion US dollars.
Keyword 2: lithium battery
With the rapid development of new energy vehicles, the demand for power batteries is driven by the market. The power batteries are basically divided into two types: batteries (mainly lithium-ion batteries) and fuel cells, but the fuel cell research and development costs and maintenance costs are too high (fuel cells). The maintenance cost is about three to four times that of the battery. It is not very suitable for the development of electric vehicles at this stage. In the face of the upcoming "blowout" of new energy vehicles, lithium batteries seem to be a magic weapon to win.
At present, lithium battery companies are facing the predicament of insufficient raw materials and rising costs. The lithium battery of electric vehicles has fatal problems such as slow charging, short cruising range and short life.
Lithium batteries have an average service life of 8 years on ordinary electronic products, while the service life on electric vehicles is only 3-5 years. When the battery capacity on electric vehicles is reduced to less than 80%, the cruising range of electric vehicles will be Significantly reduced, when the battery capacity is reduced to less than 70%, the battery must be replaced, but the battery portion accounts for about 40% of the total cost of the car. Replacing the battery is a big expense. Why is the lithium battery of an electric car so "weak"? The impact of the working environment and large-scale charge and discharge lead to the problem of short service life, and this is also an issue that cannot be changed.
Thanks to strong market demand, China's lithium battery industry has entered the first camp in the world, initially forming four major industrial areas in the Pearl River Delta, Yangtze River Delta, Beijing-Tianjin-Hebei and Central Plains. Qinghai, which accounts for 80% of the country's reserves, is trying to build another lithium industry base with national influence, relying on abundant lithium resources to take a share in the lithium battery market.
Although it is part of the first camp, in terms of technical level, there are still differences between China and the top companies in Korea and Japan. For example, there is still a big gap in product consistency.
For the lithium battery industry, improving battery recycling and reducing environmental pollution is an important factor in ensuring sustainable development of the industry. However, the recycling cost of used power batteries is high, and the level of recycling of enterprises is not high. This is the pain point of China's lithium battery industry and one of the major gaps with developed countries.
