Recently, commercialization is advanced to the warning system for the lane deviating prevention because of the progress of the sensor technology of the image processing technology etc. However, it is difficult to forecast departing several seconds after and the time to spare for the risk hedge is short. Therefore, the strategy by which reactive time of the driver is shortened is requested. This time, the torque was given to the steering wheel aiming to shorten reactive time of the driver to warning and the lane departure warning system which used bodily sensation (tactile) was developed. And, the effect was confirmed by a basic experiment with a driving simulator and the real car running experiment.
