With the development of new energy vehicles, driverless technology, and the increasing demand for comfort and safety, various safety control systems such as safe driving assistance systems and collision prediction systems will be concentrated and more widely distributed. Applications. From the perspective of the automotive electronics segment, in-vehicle electronics is no longer a “gimmickâ€, but a down-to-earth and more user-focused experience.
In the automotive chip industry, Renesas Electronics' MCUs and SOCs are recognized by many automotive product suppliers and OEMs, and are widely used in, for example, body electronic control systems, instrument panels, navigation multimedia infotainment systems, chassis and security systems. , power engine control systems, and new energy vehicles and ADAS related applications. In view of this, electronic enthusiasts interviewed Lin Zhien, Minister of Automotive Electronics of Renesas Electronics Application Technology Center, for the vehicle ADAS system.
Lin Zhien, head of automotive electronics at Renesas Electronics Application Technology Center, said that Renesas Electronics' R-Car series products have been widely used in navigation multimedia infotainment systems, and have accumulated nearly 200 million pieces of shipments and developed for ADAS related applications.
ADAS is the advanced driving assistance system, also known as the active safety system, which mainly includes the body electronic stability system ESC, adaptive cruise system ACC, lane departure warning system LDW, lane keeping system LKA, forward collision warning system FCW, automatic emergency braking system AEB. Traffic sign recognition TSR, blind spot detection BSD, night vision system NV, automatic parking system APS, etc.
In view of the current application status of the ADAS system, Lin Zhien said that the automotive ADAS is mainly based on the 360 ​​surround system. Renesas Electronics is now mass-produced with the standard camera standard definition scheme, and the standard of the high-end car is slowly extended to the low-end. Model. The digital camera HD solution will also become popular in one or two years, and the HD solution will integrate more ADAS functions, such as pedestrian detection, lane detection, and moving object detection, which will be combined with other sensors such as radar and V2X. The technology enables automatic parking and other functions.
In this regard, Lin Zhien further stated that Renesas Electronics' R-Car series products have been widely used in navigation multimedia infotainment systems, and have accumulated nearly 200 million pieces of shipments and developed applications for ADAS, especially In terms of vision, R-Car products have a high-performance image processor, built-in camera deformation correction IMR processor, and an IMP processor dedicated to ADAS image recognition, which can support up to 8 video inputs and 3 video outputs. The new generation of R-Car series adopts the 16nm process, which has the advantages of high performance, low power consumption and low performance, and also meets ASIL B requirements for functional safety ISO26262.
Of course, the more automotive electronic functions, the more ECU control will become more complex, the HMI interface will be more abundant, and the Internet of Vehicles, cloud services and user experience have become important factors for the success of the product. In this regard, Lin Zhien said that Renesas Electronics will usher in more business opportunities in the future, from MCU to SOC, in addition to continuing to develop new products that meet new functions and meet relevant standards, and also provide solutions for more product applications. To the user, the products that help them can be launched as soon as possible.
The ultimate goal of smart cars is to achieve driverlessness, that is, through the integration of sensors (cameras, radars, etc.), with the V2X system of cars and cars, cars and people, and cloud services, for short, medium and long distances. The objects and conditions are analyzed and processed to provide effective and safe control of the vehicle. For the driver assistance system, Lin Zhien added that the camera cooperates with the radar to achieve the relevant functions. The recognition capability of the system to join the ADAS application will be more, and the V2x system of the vehicle network will be the next development direction.
It is not difficult to find that the growth of the automotive electronics market and technological innovation will bring better development opportunities for automotive electronics related manufacturers. Lin Zhien emphasized that the current related auto-driving technology has been realized and measured. In the future, more efforts will be made with OEMs, product suppliers and semiconductor manufacturers to develop related technologies and promote the rapid development of the ADAS industry. To better create a new generation of smart cars.
