The 2014 Infiniti Q50 is a luxury car with a sleek, curvy that will hit dealers in and America this summer.

The first brand new technology in the Q50 is called Direct Adaptive which involves sensors in the car monitoring the position of the steering A second technology, called Lane Control, nudges you back into a lane on camera readings and sensors.

The system, fundamentally, has a goal to a wide range of steering beyond a conventional steering says Brooks. It uses an feedback loop between the and steering rack.

Previous Infiniti models, and Mercedes and BMW vehicles, nudged you into your lane.

the system starts up and everything out OK, an electric clutch, which is in the shaft between the the steering and the steering rack, disengages. At point you are in the by wire mode. As the hands move the steering the sensor reads whatever they’re commanding and then a unit calculates the required movement for the tyres.

A set of actuators on the rack then move the to that angle. As that the current draw by those motors is measured and calibrated to for different road surfaces and conditions, he says.

After all this it provides a feedback to the driver’s hands. says: Because this is many times over and again you have a continuous loop feedback system. The between the car and the road service back to the driver’s hands.


One critical point is there is a mechanical back-up that can kick in if the digital fails, but the system does what’s been used in cars for decades.

On a smooth pavement, the current to the motors is low, says There’s not the same level of feedback and the steering effort is If there is a slip on a gravel or on snow-packed highways, the motors are to a greater sensitivity.

We can filter and augment as needed. High feedbacks can be filtered out, low inputs that give you a of more control can be enhanced, Brooks.

It’s an interesting and one that he says is not necessarily to the future of autonomous driving. The is to give the driver more not less. The steering system is a force feedback controller in a where precise control precise feedback.
