[YesAuto Technology] I took the time to go to Shanghai two days ago to participate in an automobile development conference organized by a semiconductor company. During the speech, I met Zhao Fuquan (who is Zhao Fuquan) who is now a professor at Tsinghua University. Although the automotive engineers who laid the foundation for the technology platforms of Brilliance and Geely withdrew from the front-line development work, the judgment of the development of automotive technology can be said to be a time-based assessment. In his opinion, the development of automobiles will no longer rely on engines, gearboxes, and Breakthroughs in traditional core technologies such as chassis, and automotive electronics will dominate the development of future automobiles.

Seeing the current application of intelligent driving technology and the trend toward autonomous driving in the future, how much role can traditional mechanical structures play in a car? This is a question that every engineer engaged in automotive development is thinking about.

In fact, electronization has made a huge contribution to the development of automobiles in the past 30 years. 70% of technological innovations are the products of automobile electronics or the combination of automobile electronics. The implication is that vehicle engineering with a century of accumulation during this period of time There is almost no essential evolution. There are data showing that by 2020, the cost of electronic systems will account for 50% of the cost of the entire vehicle (40% at this stage).

Take fuel injection technology as an example. Early carburetor and even mechanical injection methods completed the transition to electronic injection technology in China in the 1990s. The development of electronic technology has led this change, and now it has become popular. Gasoline engine in-cylinder direct injection can be regarded as a cycle of technical routes (it has been used for a short time in the 1950s); into the 21st century, ABS anti-lock braking systems began to appear in lower-priced family cars. This means that the electronic and hydraulic systems have been integrated in the braking structure, and the subsequent ECS vehicle stability system has brought a further guarantee for car safety; the power steering system also witnessed the erosion of traditional structures by electronic technology.

Now, electronic technology has fully penetrated into modules such as power control, chassis control, safety technology, and body electronics. The innovation of automobiles will also depend on the development of electronic technology to the greatest extent. Innovation? It's easier said than done!

The advancement of electronic technology has made the development of vehicles simple and difficult. The simplicity is because the use of electronic technology allows the realization of a certain function to be realized without relying on complex mechanical or hydraulic system structures. The difficulty lies in the relative Compared with the former, the integration and verification of electronic technology will consume a lot of development resources. In addition, it is worth noting that the electronic technology based on semiconductor components itself faces great challenges, and it can almost directly determine the feasibility of the technology's application in the automotive industry and the final state of mass production.

To give a simple example, we are now focusing more on autonomous driving technology. In the development and verification phase, the processor and monitoring equipment assembled by the engineering trial car almost occupy the entire trunk. This state obviously does not have the state of mass production. Engineers It is necessary to put these complicated data processing in a traditional-sized control unit, and this needs to start with basic semiconductor components, and complete the data calculation work to maintain the function operation through a smaller processor. For example, in the Audi RS 7 self-driving model we experienced earlier this year, the calculation of the data was completed by the Infineon Aurix processor, which is one of the world's largest semiconductor companies.

Camera imaging technology

Whether it is consumer electronics or automobiles, the expansion of functions based on image capture and analysis technology has great development prospects. In other words, camera applications can support mobile phones or other terminal devices to implement functions such as gesture control, and it is also a self-photographing function. , Another use of the camera. In terms of car safety, the use of cameras has also been around for a long time. In the early days, the goal was to reduce visual blind spots. From reversing images to current holographic images, after the addition of image analysis technology, the function of lane keeping has been realized. Now it is gradually being implemented. Braking is also based on image information.

Transition from planar imaging to stereo imaging

The technical application of the 3D camera has also brought new opportunities for the development of fatigue monitoring. The original technical structure has affected the accuracy of the system’s monitoring of the driver’s condition to a certain extent, especially when it comes to drivers wearing glasses. Coupled with the backlight environment, traditional cameras will be subject to greater interference, which has caused many manufacturers to encounter obstacles in the development of this technology, and thus delays in integrating them with model products.

Of course, in the fatigue monitoring system, the new camera technology still needs to obtain the traditional ToF technology (the near-infrared light emitted by the sensor is reflected after encountering the object, and the processor calculates the time difference between the emitted and received light to obtain the distance information. This is based on the depth calculation. At this stage, the data and the plane image are combined to generate a three-dimensional contour. After using the 3D camera, the calculation accuracy is improved.) The support can play the best effect.

Development environment

Companies like Infineon provide hardware solutions for the development of automotive electronics, but the final technical application has to go through system development, verification, and vehicle matching. Therefore, developers are still facing a huge For OEMs, the resources that can be deployed are relatively rich, and third-party service companies also have certain development and integration capabilities, but for those emerging companies that have just entered the field of car manufacturing, especially those small-scale companies For them, entering the door of electronic system development may still have to step up to a higher threshold.

After seeing this situation, Infineon established an automotive electronics ecosystem 3 years ago by relying on its position in the semiconductor industry and its customer base. In this way, it can help companies seeking outsourcing development and those with development capabilities. The company builds a bridge of communication. This O2O approach not only promotes the cooperative relationship between the supply and demand sides, but for Infineon, it provides opportunities for capturing a larger market, especially through such a platform and some independent scientific research institutions. The achievement of the cooperation means that the domestic electronics industry in China has achieved penetration.

Edit summary:

Ten years ago, Nokia felt that the form of mobile phones would be the same, and there would not be much breakthroughs, but the emergence of Apple has gradually subverted existing cognition, and cars are the same. With the development of electronic technology, smaller sizes and computing Faster processors and the application of miniature high-definition cameras will have richer functions implemented in the automotive field. In the foreseeable future, electric vehicles and autonomous driving are more like a single unit of a huge electronic system. In contrast, the development investment of traditional technology may no longer consume a lot of development resources due to the solidification of the technology.
