As the pace of consumer electronics growth slows, the industry is in urgent need of finding the next application to drive development, and cars are expected. Autopilot technology and advanced driver assistance systems (ADAS), which have been widely discussed and paid attention to in recent years, are applications with future prospects in automobiles. Although automatic driving has not yet landed, the ADAS system has been widely used in more and more vehicles.

The advanced driver assistance system uses various sensors installed in the vehicle to collect environmental data inside and outside the vehicle at the first time, and to perform technical processing such as identification, detection and tracking of static and dynamic objects. Active safety technology that allows drivers to detect possible hazards in the shortest time to attract attention and improve safety, usually including navigation and real-time traffic system TMC, electronic police system ISA, car networking, adaptive cruise ACC, lane bias Motion alarm system LDWS, lane keeping system, collision avoidance or pre-crash system, night vision system, automatic parking system, traffic sign recognition, blind spot detection, driver fatigue detection and other systems. Therefore, ADAS is not a single product, but a complete system consisting of different technologies/products to assist drivers in driving safer and more convenient. Each technology has unique requirements and feature sets for image sensors to achieve optimal system performance.

ADAS covers a wide range of functions that are rapidly being applied to new car designs due to government regulations or the natural needs of the market. New car safety assessment programs are being developed in most parts of the world, the most active of which are the European (Euro NCAP) and US (US NCAP) new car safety assessment programs. The development of these safety assessment plans has pushed the ADAS technology to the market, and the product functions such as AEB will become the standard in the market by 2020. At the same time, users' demand for autonomous driving convenience is rapidly increasing, especially for SAE Level 3 and above, which will drive companies to use more advanced ADAS technology in new cars. Just as those technologies that follow the product adoption curve, more advanced systems can occur in markets that can afford to increase costs, while low-cost, cost-effective systems are used in different OEM lines. From this point of view, advanced ADAS systems are expected to grow fastest in North America and Europe, while some mainstream products will grow in all regions. Sensor supplier OmniVision has developed a complete product suite to meet the needs of various regions and markets, and they are deploying a range of new products and technologies to meet future market needs, such as the OV2775 The Reference Design System (ARDS), a reference design that can be used in a wide range of industries, is powerful and helps customers get their products to market quickly through their fully certified automotive-grade design. In other words, this reference design has been tested. And verification, customers can directly apply, reducing the burden of overall design and testing. In addition, the ARDS solution allows customers to eliminate the need to debug the camera design and focus on producing superior products.

Indeed, if the ADAS system is widely used, it will be a huge market for sensor manufacturers. According to the US New Car Evaluation Regulations (US NCAP), all new cars in the United States must be equipped with a rearview camera after 2018. This is a big market opportunity for sensor companies, but it also means that the low-end sensors currently used in the market may be heavily marketized. At the same time, there is an opportunity for differentiation in high-end rearview imaging systems (RVC). At present, most of the new cars sold in the US have installed the RVC system, and there may be no significant demand growth in image sensors, but a performance leap and upgrade is expected, from the existing VGA sensor to higher performance. Higher resolution, feature-rich products such as OV9716, OX01B40 and OX01A10 from Howard Technology. At the same time, they are also expanding the ARDS platform to integrate some new image sensors and SoC/SiP to help customers bring products to market faster and reduce development costs. In general, image sensor companies are developing a variety of products other than RVC, such as the Surround View, Park Assist, etc., to bring additional benefits to automotive OEMs and Tier 1 companies. Values ​​also ultimately benefit customers. Howard Technology has a full range of products and technologies to meet these needs, from its motion-free artifact HDR to the state-of-the-art LFM+HDR technology to flexible architecture design and ARDS platform, providing customers with the best combination of performance and features. ”

In addition to sensor products, Howell Technology has always had outstanding products and rich R&D experience in the automotive industry, such as the industry's low-light imaging benchmarks - OV10642, OV10652 and OV10650, which are now widely used in front-view applications. The LED flashing reduction sensor is also the industry's first LFM sensor to be used in production vehicles. In addition, Howe Technology is constantly innovating to develop new products for multiple markets to meet the needs of various systems, such as the OX02A10 for camera monitoring systems/streaming rearview mirror applications, which has industry-leading LED flicker elimination. It is equipped with HDR performance to eliminate motion artifacts; and the next-generation forward-looking sensor OX03A10, which combines the success of the OV10640 and OV10650 for better performance and features.

In addition to leading technologies and products, it is important to build strong partnerships in the automotive market, as has the ADAS system. In addition to sensors, algorithms are also very important for ADAS systems. ADAS systems and algorithms are highly dependent on the images used, as the algorithms are adjusted around these images. Howe Technology also works closely with the ADAS supplier ecosystem, including hardware, lens, serializer and algorithm providers. Howe Technology can provide a variety of color filter array (CFA) sensors, including RCCC, RCCB and RGGB, to ensure that Howe Technology can cope with all ADAS ecosystem issues, and develop and produce the most advanced with ADAS partners and customers. Reliable, high performance sensors for use in the product market. In addition to the ADAS application, Howe Technology also works closely with Smart Eye, a driving monitoring system partner. They chose the OV2311, a small form factor with excellent NIR performance, low power consumption and ASIL B certification, combined with its next generation of algorithms and hardware solutions. This highlights what it has been emphasizing to help eco-friends bring high-performance, high-quality turnkey solutions to the market.

According to the analysis of the Geshi Automobile Research Institute, with the increasing assembly rate of ADAS technology on new vehicles, China's ADAS market will enter a period of rapid penetration in the next 2-3 years. It is expected that by 2025, high-level self-driving cars will be mass-produced after 2025. The ADAS market will tend to be stable. Undoubtedly, cars will be another important market for sensor applications.
