Nexteer Automotive has introduced its Direct Drive Hand Wheel Actuator (DD-HWA), marking a significant step forward in its Steer-by-Wire (SbW) development. This new solution raises the bar for steering precision, system integration, and vehicle design adaptability—empowering carmakers to create next-gen driving experiences in software-driven vehicles and across all stages of assisted and autonomous driving. Designed for both 12V and 48V electrical systems, DD-HWA is built to support conventional, hybrid, and electric platforms on a global scale.
At the heart of Nexteer’s Motion-by-Wire suite, DD-HWA replaces the traditional mechanical steering link with an all-electronic system. This shift enables greater flexibility in interior layout, improved vehicle dynamics, and new safety features.
The DD-HWA system marks a significant advancement in automotive steering technology, designed to elevate the driving experience for both manufacturers and consumers. It delivers a refined steering feel characterized by confidence, smoothness, and precision across all driving conditions. The system’s high-frequency responsiveness enables quick, agile handling, ensuring a seamless and controlled experience behind the wheel.
Engineered for comfort, DD-HWA minimizes torque ripple, resulting in smoother feedback and a more natural driver touch. Its advanced control system maintains consistent performance even during demanding maneuvers, enhancing overall stability and driver confidence. This makes it especially suitable for modern vehicles that demand both precision and comfort in equal measure.
A key highlight of the DD-HWA system is its flexible packaging. It is available in both compact low-mount and high-mount configurations, giving automakers greater design freedom. The low-mount setup fits neatly under the dashboard, while the high-mount option places the actuator directly behind the steering interface—enabling new possibilities in cabin design and interior space optimization for next-generation vehicles.
The technology is fully adaptable to all powertrain types, particularly electric and hybrid vehicles, where it helps optimize space utilization and improve energy efficiency. Safety is also a core focus: the system’s robust mechanical design ensures precision and reliability, while redundant architectures safeguard against failures, guaranteeing dependable operation under all conditions.
Furthermore, DD-HWA incorporates a proprietary high-performance motor, developed in-house to ensure top-tier quality, supply chain control, and cost-effectiveness. Its streamlined design reduces component count, improving durability, ease of assembly, and system integration. With multi-channel angular sensors and precision gear architecture, it offers accurate position sensing and advanced diagnostic capabilities. Operating seamlessly on both 12V and 48V electrical systems, DD-HWA provides flexibility across various vehicle platforms—setting a new benchmark for next-generation steering systems.
“Our Direct Drive Hand Wheel Actuator is another milestone in our by-wire journey, helping automakers deliver advanced features and adaptable vehicle platforms,” said Robin Milavec, President, Chief Technology Officer, Chief Strategy Officer, and Executive Board Director at Nexteer Automotive. “By bringing together high-end mechanical systems, intelligent control software, and flexible design, we’re enabling carmakers to offer standout user experiences while preparing for the future of mobility.”
