The three-year epidemic drew a rest, and Auto Shanghai, the first Class A auto show in 2023, kicked off in the limelight.

　　New forces are springing up like mushrooms after a rain, competing with old car companies on the battlefield; A group of domestic and foreign component manufacturers are also rubbing their hands and showcasing the long dormant "hard core black technology".

　　Looking at the automotive technology and supply chain exhibition area, Deke Intelligent Control, located in the 2.2H Pavilion, fully showcases its latest research and development achievements and innovative solutions in the L2-L4 level intelligent steering and wire controlled steering fields.

　　At the inaugural exhibition of Active Rear Wheel Steering (RWS) technology, it has become a true C-position explosive.

　　Active Rear Wheel Steering (RWS) technology - born for vehicle cornering issues

　　The front wheels actively turn, causing the rear wheels to deform elastically and then follow in steering. During emergency steering, a large center of mass sideslip angle is generated, causing tailspin and other phenomena, reducing the vehicle's handling stability; It is also difficult to navigate narrow road sections and lacks driving flexibility.

　　Active Rear Wheel Steering (RWS) technology is developed to solve the problem of vehicle cornering, and has high applicability in various working conditions such as turning on narrow roads, entering and exiting parking lots, parking on the side, and reversing and entering the vehicle.

　　A B-class sedan with a length of over 5m can reduce the turning radius by 1.03m when equipped with active rear wheel steering, making it as flexible as a compact model and greatly improving the user's driving experience.

　　Unlike passive rear wheel steering, active rear wheel steering achieves active control of rear wheel swing angle by driving a pull rod through a motor.

　　Deke Intelligent Control RWS Active Rear Wheel Steering Technology

　　1) The motor, controller, and mechanical parts are integrated in one, with a volume about 30% smaller than that of parallel rear wheel steering;

　　2) The 720W high-power direct drive motor outputs a super large thrust of 13KN, achieving industry-leading ± 6 ° rear wheel angle swing, and the speed meets the requirement of ≥ 22mm/s;

　　3) To prevent road impact and unexpected steering, the T-shaped screw and nut have self-locking function. The screw can withstand a reverse thrust of ≥ 30000N;

　　4) Meet functional safety ASIL-D level, FTTI meets vehicle safety requirements, and ECU system supports OTA upgrade function.

　　Rear wheel steering technology has entered the homes of ordinary people

　　The emergence of Deke Intelligent Control active rear wheel technology is at a timely time.

　　Based on the demand for comfort and multi child family travel in the C-end market, B-C class sedans and SUV models have seen rapid growth. However, the contradiction between body size and driving flexibility is difficult to solve, and the difficulty of turning and turning vehicles in narrow spaces is becoming increasingly apparent.

　　In China, I think there are still three future opportunities, one of which is to further deepen electrification, "Wang Chuanfu said recently at BYD's 2022 performance meeting.

　　The rear wheel steering technology is based on an electronic and electrical architecture, making it easier to implement on pure electric platforms; In order to address mileage anxiety, electric vehicles have an increasing storage space for chassis batteries and a longer wheelbase compared to traditional passenger cars, making the demand for front and rear steering linkage even more urgent.

　　The rear wheel steering function was only exclusive to millionaire cars for a long time. But in today's era of rapid progress in electrification and consumer upgrading, its supporting models have dropped to within the range of 500000 yuan.

　　The Deke Intelligent Control active rear wheel steering product has completed its first round of customer acceptance and is expected to achieve mass production in the second half of 2024, providing consumers with a more optimized driving experience and providing practical and effective intelligent highlight support for new car marketing.

　　The "Second Entrepreneurship" of the First Batch of EPS Researchers in China

　　The automotive chassis has undergone four transformations, corresponding to the steering system, namely mechanical steering, hydraulic steering, electric power steering, and wire controlled steering.

　　Time can be traced back to 2001, when mechanical steering was still the world, hydraulic steering was in a rapid development period, and the market recognition of electric power steering was very low.

　　In 2001, while pursuing my doctoral degree at Tianjin University, I stumbled upon a lecture by an American engineer and learned about the third-generation electronic power steering. At that time, several of my brothers and I thought this product was very advanced, environmentally friendly, and energy-saving, and wanted to study it as a research topic, "said Dr. Wang Hao, founder of Deke Intelligent Control, in an interview.

　　Cherish simple ideals and water the fruits of scientific research with sweat. In the laboratory of Tianjin University, the first independently developed EPS controller was born in this young and astringent combination of three master's students who were paired with doctoral students.

　　As is well known, the process of advanced technology vector production and productization migration greatly tests the ability of enterprises to scale validation and engineering.

　　In 2009, Tianjin Deke Intelligent Control Co., Ltd. was officially established and embarked on the path of mass production of electric steering assemblies, marking its 14th year to this day; Developed and mass-produced an intelligent steering series for a full range of models including passenger cars, commercial vehicles, and autonomous driving, with a cumulative delivery of over 1.8 million sets of high-quality products to global frontend host customers.

　　Maintaining hunger at all times is not only an attitude, but also an ability

　　Maintaining hunger at all times is not only an attitude, but also an ability. Overreliance on the market dividends brought by existing products, sleeping on the credit card, lacking continuous attention and insight into advanced technology and market demand, will ultimately be drowned out by the tide of the times.

　　In 2011, the autonomous driving market was just beginning to sprout. Driven by vehicle companies and domestic universities, Deke Intelligent Control has launched research on unmanned driving by wire technology, delivering a wire controlled steering product for the first demo model in just 4 months.

　　To be honest, those months were indeed very difficult, but when we see the results, we do feel very relieved. Countless exciting moments in life are composed of countless such small things

　　Mastering the development capability of the entire industry chain of steering system controllers, motors, and sensors, and having complete autonomy in all key software and hardware technologies is the foundation for Deke Intelligent Control to achieve "domestic substitution", which is a strong guarantee for Chinese independent car companies in the face of foreign technology lockdowns.

　　Some people say that starting a second business is "killing" the past self, and this "killing" also means evolution, change, and rebirth. After 20 years of ups and downs, Deke Intelligent Control has embraced every new change in the automotive industry with craftsmanship and strength, deeply rooted in the field of automotive chassis, always young and hungry.

　　epilogue

　　In 22 years, the sea has already become a mulberry field; But in 22 years, for a company, especially in the field of automotive safety critical components such as steering systems, they can only choose to persist in doing one thing well for decades, achieving self revolution and rebirth time and time again.

　　Deke Intelligent Control will tirelessly strive to become a leader in China's intelligent steering industry, achieving the beautiful vision of "applying every vehicle to China's safe intelligent steering system".
