TRW has developed a new commercial vehicle steering technology that will enable trucks to perform some semi-autonomous driving. Presented at the 2014 IAA in Hanover, Germany TRW says the ReAX system will be ready for production in 2017 and is already working with a major vehicle manufacturer to research and develop semi-autonomous vehicle functions using the technology.
Called ‘ReAX’, it merges proven steering systems – hydraulic power steering (HPS) for commercial vehicles and electrically powered steering (EPS) belt drive for passenger cars. The combination improves driver control and stability.
ReAX can also enable semi-automated driving functions and advanced driver assist systems including lane departure warning and lane keeping assist. These systems can further enhance safety and comfort. TRW has been demonstrating its semi-automated driving capabilities to automakers in recent weeks as well.
TRW’s global commercial steering systems vice president, Andreas Weller, said: “Safety, comfort and efficiency are as important in commercial vehicles as in passenger cars, even more so when you consider that trucks workplaces where drivers spend long periods of time every day. This new technology focuses on making the driving task as safe and comfortable as possible.”
How ReAX works
ReAX uses proven hydraulic power steering to provide the torque required to steer large commercial vehicles, while an EPS belt drive provides the precision and control. Together they reduce steering efforts at low speeds and improve stability at higher speeds.
“TRW has more than a decade of experience in combining these two technologies,” said Weller. “A column drive variant has long been used for bus and motor home applications. Building on our experience, ReAX now leverages belt drive EPS to offer trucks an ideal solution.”
TRW has an extensive range of commercial vehicle steering technologies and has just signed a long-term supply agreement with Daimler Trucks.
