'Independent Rear-Wheel Steering System'
The Only One Among Asian Parts Manufacturers

[Asia Economy Reporter Kiho Sung] Hyundai Mobis's independent rear-wheel steering system has won the Innovation Technology of the Year award from Automotive News, a North American automotive media outlet. Automotive News holds the PACE program awards ceremony annually to announce outstanding innovative technologies from global parts manufacturers.

According to the automotive industry on the 21st, the 28th PACE program this year was held on the 19th (local time) in Detroit, the home of the North American automotive industry, as part of the North American International Auto Show. The PACE program is divided into two categories: the production division called the PACE Award and the advanced division called PACE Pilot. Hyundai Mobis was the final winner in the PACE Pilot category. Hyundai Mobis is the only Asian parts company to win in the advanced technology category.

Hyundai Mobis's independent rear-wheel steering system is a technology developed successfully this year after about two years of research and development. It advances the rear-wheel steering system, mainly installed in large sedans, sport utility vehicles (SUVs), high-performance cars, and electric vehicles, allowing the rear wheels to move in different directions up to nearly 10 degrees. The core of the technology lies in the electromechanical steering system, the controller that manages it, and the software logic.

When this technology is applied, it reduces the turning radius by about 25% when the vehicle turns, significantly enhancing safety and ride comfort during high-speed cornering. It is expected to be useful in domestic and European markets where road widths are narrow or parking spaces are limited.

Currently commercialized technologies allow the two rear wheels to move about 10 degrees in an integrated left-right steering system and about 3 degrees in a separated left-right system. Hyundai Mobis has succeeded in developing technology with performance more than three times greater than these.

Hyundai Mobis's independent rear-wheel steering system is expected to be widely used especially in electric vehicles with extended wheelbases (the distance between the centers of the front and rear wheels) designed exclusively for electric vehicle platforms. The rear-wheel system is advantageous for electric vehicles in terms of vehicle weight and design.

As the large electric vehicle market grows, Hyundai Mobis's proactive development of this technology has reportedly received favorable evaluations from the judges. Pickup trucks, which are popular in the North American market, are also expected to be a major target for Hyundai Mobis's orders.

Byunghoon Lee, Executive Director of Hyundai Mobis Chassis Safety BU, said, "Proactive research and development activities specialized for autonomous driving and electric vehicle markets have led to innovative technology," adding, "We will take the lead in developing new e-corner module technology, where all four wheels move independently, surpassing the independent rear-wheel steering system, to secure a global market position."

Meanwhile, the e-corner module being developed by Hyundai Mobis is a next-generation mobility technology that integrates steering, braking, and suspension by mounting motors on all four wheels. The current electric vehicle drive motor disappears, and the vehicle moves by the power of each of the four wheels. The independent rear-wheel steering system is the core steering technology of the e-corner module.

Applying the e-corner module enables crab driving, which moves like a crab, and 90-degree rotational parking by linking with the electronic steering device called 'steer-by-wire,' instead of the existing hydraulic system.
