Lane Departure Warning Systems which indicate inadvertent lane departure with a simple chame, were introduced on cars more than 3 years ago.
All manufacturers are working on systems which keeps a car drifting out of lane, typically using computer-controlled steering.
The new Infiniti system is simpler: When the vehicle drifts towards the lane marking, the warning chime sounds and in addition, the vehicle’s dynamic stability control system pulses the brakes on the opposite side.
The system needs a four-wheel steering in the engineering arsenal but nevertheless, it is a lower cost and a gentler effectiveness.
A camera just above the interior rearview mirror and the computer with which it communicates, assume greater importance with this active addition to a warning chime.
The camera and its computer are produced by Valeo using some technology licensed from Iteris.
