Emergency Lane Keeping
A
ssist (ELKA)
The emergency lane keeping assist
(ELKA) system identi󽗉es lane lines ahead
through a multi-purpose camera and
identi󽗉es vehicles approaching from
behind on the adjacent lanes through
rear corner mmWave radars. It comes
to work within the 50 km/h-150 km/h
vehicle speed range when the vehicle
drifts out of solid lane lines, is about
to cross a road edge, or has a risk
of colliding with oncoming vehicles or
vehicles that are passing it on adjust
lines. The system activates EPS system
to provide reverse torque, keeping the
vehicle in the current lane.
