Setup speed area is 72−180 km/h (45−112 mph).

If functions from straight line to 230R when car runs 80 km/h (50 mph).

This system detects a slight movement of a steering wheel.

This system turns on and off according to operation of the LKAS switch.

Line width, length, and continuousness detected as a feature of the line from the image captured by the LKAS camera, in order to judge and evaluate whether it is a lane, and recognized as a lane on the road.

Lateral direction control to maintain a lane consists of recognizing a lane on the road correctly by the image process system. This system can recognize complicated lanes such as broken lines, double broken lines, and blanches.

Data obtained from the image process system is calculated with a control unit and compute the steering torque necessary to assist the LKAS and realizes the LKAS using the EPS current control.

Driver's steering operation to maintain the driving lane is widely decreased thanks to this system and driving stability against disturbance such as abrupt cross wind is increased.
