Why NABTESCO Steer-By-Wire?

Traditional steering systems with hydraulics and mechanical connections are becoming a thing of the past. Modern Steer-By-Wire systems eliminate the need for hydraulic oil and mechanical lines, providing: ✅ Oil-free technology – eliminating the hydraulic system means no leaks, lower operating costs, and greater reliability.

✅ Plug & Play – easy integration – Steer-by-Wire systems are modular and can be easily adapted to various vehicle platforms.

✅ Precise motion control – no mechanical backlash, resulting in exceptional steering accuracy and immediate system response.

✅ Digital control and integration with autonomous systems – compatibility with ADAS, AI, and autonomous driving systems.

✅ Improved driving dynamics and driver comfort – optimization of steering force and automatic adjustment to road conditions.

✅ Reduced weight and space savings – removing the hydraulic system allows for more flexible vehicle design.

✅ Increased safety – electrical system redundancy, no risk of hydraulic failure, and immediate lane corrections.
