Schaeffler, a German auto parts company, has started series production of its new mechatronic rear-wheel steering system.

An unnamed vehicle manufacturer is using the system in a new electric SUV, and other vehicle models featuring the system will go into production soon, the company said.

Schaeffler’s rear-wheel steering system is made up of two subassemblies: a precision mechanical system with an adaptive planetary roller gear from the company’s Industrial Division; and a powerpack comprising the electronics, electric motor and software. 

The Schaeffler product meets the safety requirements of Automotive Safety Integrity Level D (ASIL D). EV drivers benefit from its precise vehicle motion since it offsets the drawbacks of a larger wheelbase required to accommodate the underfloor battery. A longer wheelbase increases turning radius and decreases maneuverability.

“Thanks to its optimized inner design, our rear-wheel steering system is more compact and requires less installation space in the vehicle,” said Clément Feltz, head of the Chassis business division at Schaeffler. “As a result, automakers can save up to 15% in weight compared to alternative systems.”
