Mazda’s Lane-Keep Assist System (LAS) promotes safer driving by providing appropriate steering assistance. The system allows drivers to choose between Lane-Trace, which provides steering assistance early in order to help keep the vehicle centered in the lane and Lane Departure Avoidance, which only comes into play if the vehicle begins to leave its lane. LAS uses a windshield-mounted camera to recognize lane-markings on the road and activates at speeds above 60 km/h.
LAS in action (Lane Departure Avoidance)
Helping to avoid unintentional lane departures
When Lane Departure Avoidance is selected, the system works to prevent unintentional lane departures due to driver inattention. If the system predicts that the vehicle is about to stray from its lane, it provides steering assistance to return the car toward the center of the lane.
When Lane Trace is selected the system reduces the burden of driving by providing continuous steering assistance to help keep the vehicle centered in its lane. On bends the systems help the driver to drive more safely by guiding them toward a steering angle that matches the curvature of the road. Lane Trace is achieved simply by having LAS provide steering assistance from an earlier stage than with Lane Departure Avoidance.
