Nexteer reveals autonomous-ready steering at NAIAS

Nexteer steering on demand system

Nexteer Automotive unveiled its two latest steering technologies at this week’s North American International Auto Show in Detroit.

The Steering on Demand and Quiet Wheel Steering technologies should, the company hopes, tap into the increasing automation of passenger vehicles.

Steering on Demand enables the transition between driver and automated driving control through safe, intuitive steering transitions for vehicles capable of SAE levels three, four and five automated driving. The system also lets drivers tailor their driving experiences through various driving performance options including a sport, comfort and manual override mode.

Quiet Wheel Steering modifies the steering wheel rotation when a vehicle completes an automated directional change. Because the steering wheel remains still during automated driving, potential hazards of a fast rotating steering wheel are eliminated and the driver's safety and sense of security are enhanced.

Vehicles equipped with Quiet Wheel Steering may also be fitted with a stowable column that automatically retracts into the dashboard when automated driving is engaged, increasing available space for driver comfort and other activities.

"The pace of re-defining mobility has increased exponentially," said Frank Lubischer, chief technology officer at Nexteer Automotive. “Consequently, we're innovating in not just what we do, but how we do it. The traditional automotive development methods have been quite sequential and linear, typically taking an idea to production readiness over several years; whereas, a disruptive, parallel method of rapid prototyping and user tests moves much faster. At Nexteer, we've blended these two methods into our version of an iterative, rapid prototyping and design approach. This lets us quickly develop, prototype, improve and then move an idea on to the next stage of industrialisation."

Lubischer said the two technologies were the results of the company's R&D approach and in-house capabilities.

"These technologies are intended to make the automated driving experience more intuitive and safe as the industry evolves into this enhanced form of mobility," he said.

Both introductions use the firm’s steer-by-wire technology. While steer-by-wire does not require a mechanical link between the road wheels and steering wheel, the company can tune the system for steering feel and responsiveness. Reliable system performance is also enhanced through integration of sensors and mechanical technologies.

Nexteer Automotive has a global workforce of more than 13,000 serving more than 50 customers in every major region of the world. The company has 24 manufacturing plants, five regional engineering centres and 11 customer service centres in North and South America, Europe and Asia. Its customers include BMW, Fiat Chrysler, Ford, GM, PSA Group, Toyota and VW, as well as car makers in India and China.
