5.4.7 Lanekeepingaid(LKA)
system*
The lane keeping aid system is designed to
reduce accidents caused by unconscious lane
departure.
The lane keeping aid system detects the lane
markings on the road and curbs through the
intelligent front camera installed on the front
windshield, and detects the road guardrails
through the millimeter wave radar installed
in the front of the vehicle.In addition, it
analyzes the driver’s driving behavior and
vehicle movement status. When the driver
unconsciously departures from the lane due to
fatigue, distraction, or a phone call, the AEB
issues a warning or intervenes in turning of
steering wheel to assist in corrective steering
adjustment.Generally, a warning will be issued
or turning of steering wheel will be intervened
in when the front wheels cross a lane marking

When the driver selects “Steering assist” or
“Steering assist and warning” as the LKA
mode and the operating conditions of the
lane departure aid system have been met,
the system monitors the torque applied to the
steering wheel.When the driver keeps hands
off the steering wheel for a long time, the
system will alert the driver.
