[Introduction] Zhao Mingyu, director of Renesas Automotive Business Unit, believes that ADAS is the pre-installation focus of the current automotive industry. All new models will be equipped with ADAS systems more or less next year. In response to the trend, Renesas unveiled the ADAS HD 3D surround view, standard definition look-around, and 12.3-inch virtual dashboard solution at the Munich Electronics Show.
The wave of intelligence has also recently entered the automobile manufacturing industry. Smart cars and self-driving cars have clearly become the mainstream development trend in the market. At present, overseas driverless car technology is close to commercialization, but in terms of domestic automobile manufacturing and market, the development potential of the driverless car civilian market is still not clear, and there is still a long way to go in technology.
Zhao Mingyu, director of automotive electronics solutions at Renesas, said: "The driverless car is a direction, but it is still far from the Chinese car manufacturers. At this stage, we are more optimistic about ADAS. By 2017, all new models will be more or more. Or less equipped with the latest ADAS systems, such as 360-degree surround systems, lane departure warnings, reversing aids, virtual dashboards, etc."
At the Shanghai Electronics Show in Shanghai in mid-March, Renesas highlighted the high-definition (720p) 3D surround vision solution, SD 360-degree look-around solution and virtual dashboard solution, as well as development templates and dynamic demo videos, Renesas Zhao Mingyu, director of automotive electronics solutions, personally explained the scene for the author, click to view the video.

Figure 1: Renesas Virtual Dashboard Solution with R-Car RH850/D1x Graphics Processor a that can handle 3D graphics
Renesas' 12.3-inch virtual dashboard solution uses the R-Car RH850/D1 series of graphics processors that can handle 3D graphics. Director Zhao Mingyu said that more and more OEMs are expected to adopt 3D virtual graphic instrumentation systems in the near future.
With the increasing use of color LCD screens in instrumentation systems, small and medium-sized cars are also more likely to combine mechanical hands and graphic displays. In high-end cars, the "no mechanical pointer" display that seeks easy identification and comfort has made great progress. A 3D image that can be beautifully and easily recognized on a large-size, high-resolution screen has been considered an aspect of the car's personality. It is foreseeable that in the future, even in low-end models, the trend of large-size and high-resolution display screens will continue to develop, and the instrument systems currently used for 3D graphics used in high-end cars will be widely used.
In order to better popularize the car virtual dashboard system, it is necessary to have the ability to drive 3D graphics, display rich and realistic images, display the screen of the instrument as quickly as the auxiliary program, and achieve high reliability without unauthorized access to the system. Sexuality to continuously transmit accurate meter information to the driver; in addition, the performance of many electronic equipment units and communication systems in the vehicle needs to be enhanced.
The functionality and performance of the Renesas R-Car RH850/D1x overcome these issues, and because Renesas users can leverage the R-Car ecosystem of more than 170 companies, they will be able to quickly develop 3D graphics cluster systems. . Renesas is currently promoting the use of 3D graphics on a large scale.
The Renesas R-Car Series SoCs provide a high-performance Human Machine Interface (HMI) for high-end automotive cockpit systems. Renesas also provides instrument control support via the RH850/D1X microcontroller, which is ideal for low- and mid-range automotive systems.
The top five reasons to choose Renesas as a 3D virtual dashboard development partner are:
First, it is easy to develop a 3D graphics instrumentation system by working with a Renesas partner. While good visibility and high-quality design are extremely important to improve the recognizability and comfort of a full-graphics instrumentation system, at the same time, if users have insufficient experience in 3D graphics development, the time required for development will be It is a big obstacle. Based on Renesas' extensive experience in HMI solution development and a partner company with expertise in graphics system development, Renesas offers solutions that easily display images created by graphic designers as instrumentation systems, making it easy for system vendors Develop your own 3D instrumentation system.
Second, Renesas can help you quickly start up the instrumentation system, for example, when the driver opens the side door of the cab, or when the auxiliary program is started, the system can immediately display the picture or output the audio at high speed. Renesas, along with a partner in the R-Car ecosystem, offers solutions that support high-speed system startup, fast display of instrument screens and audio output.
Third, to ensure driver safety and prevent car hackers by providing functional safety and security solutions. If the instrument system fails, it can cause serious accidents, so in order to provide the driver with the correct information, these systems need to continuously monitor whether the information being output is correct. If the system fails, it needs to be detected immediately. To achieve a highly reliable system, the R-Car D1 supports the ISO26262 standard for automotive functional safety. Renesas offers a functional safety support program to implement a functionally secure system.
In addition, because it is necessary to prevent hackers from outside the system to ensure the system is safe and reliable, the RH850 32-bit MCU with hardware security function can be combined with the R-Car D1 series to construct a system that ensures data robustness and hacking prevention. become possible.
Fourth, the highest system flexibility and ease of design can be achieved by using R-Car D1 , which supports a wide range of communications and network types . The R-Car D1 contains the various communication interfaces required for the instrumentation system. Since the R-Car D1 supports this range of interfaces, including Ethernet AVB for connecting navigation systems, USB for smartphones, and CAN-FD for in-vehicle infotainment, it delivers maximum system flexibility and ease of use. design.
Fifth, you can make full use of the development assets of Renesas 2D graphics cluster RH850/D1x. The RH850/D1M series MCUs are capable of instrument control and 2D graphics display on a single chip, and are widely used in a variety of vehicles. Since the 2D graphics system in the R-Car D1 SoC is identical to the RH850/D1M, system manufacturers can use these 2D graphics to develop assets and develop 3D graphics systems for R-Car D1. In addition, for instrument control, system manufacturers can also use R-Car D1 in combination with RH850/D1M to perform this system.
Samples of the Renesas R-Car D1 series are available now, with volume production scheduled for March 2017. Production is expected to reach 100,000 units per month by March 2018.
Renesas also exhibited a 0.9L air-cooled 20KW inverter + DC-DC converter + motor integrated system for new energy vehicles at the Munich Electronics Show. The volume is significantly smaller than the liquid-cooled structure. At present, Renesas laboratory engineers can achieve 40KW power and rated power of 80KW. Director Zhao Mingyu pointed out: "This power is enough for domestic EV/HEV car manufacturers." (For physical samples, see Demo video 3).
