Toyota Camry: LTA (Lane Tracing
Summary of functions
While driving on a road with clear white (yellow) lane lines, the LTA
system warns the driver if the vehicle may deviate from the current
lane or course*, and also can slightly operate the steering wheel to
help avoid deviation from the lane or course*. Also, while the dynamic
radar cruise control with full-speed range or dynamic radar cruise control
is operating, this system will operate the steering wheel to maintain
the vehicle's lane position.
The LTA system recognizes white
(yellow) lane lines or a course*
using the front camera. Additionally,
it detects preceding vehicles
using the front camera and radar.
