Introducing Next Generation Steering

YOKOHAMA, Japan – A conventional steering system directs tire movements by transmitting steering inputs to the tires via a mechanical link. Nissan Motor Co.'s next-generation steering technology, unveiled at its Advanced Technology Briefing last week, reads the driver's intentions from steering inputs and controls the vehicle's tire movements via electronic signals.

The system controls and insulates the vehicle from unnecessary road-generated disturbances to deliver only the necessary performance feel to the driver.

For example, even on a road surface with minor ridges or furrows, the driver no longer has to grip the steering wheel tightly and make detailed adjustments, so traveling on the intended path becomes easier.

Accompanying this next-generation steering technology, Nissan has also developed a camera-based straight-line stability system to further enhance on-center driving capability.

This system is a world-first technology that improves vehicle stability by making small input angle adjustments so the vehicle will accurately trace and continue as planned in the lane it is traveling.

If the vehicle direction changes due to road surface or crosswinds, the system acts to minimize the effect of these conditions resulting in reduced steering input from the driver.

This next-generation steering technology's high reliability is achieved by multiple ECUs. In the event a single ECU malfunctions, another ECU will instantly take control, and in extreme circumstances such as the power supply being disrupted, the backup clutch will act to connect the steering wheel and wheels mechanically, ensuring continued safe travel.
