Abstract:
1. A lane departure prevention system for a host vehicle, comprising: a detector configured to detect a driving lane, a judgment device configured to determine whether there is a departure tendency of the host vehicle from the driving lane detected by said detector, a yaw moment computing device configured to compute a target yaw moment in a departure-avoidance direction when said judgment device determines that there is a lane departure tendency, wherein the yaw moment computing device is configured to correct said target yaw moment by decreasing the target yaw moment when an estimated lateral acceleration predicted for the host vehicle is lower than a threshold, wherein the threshold is based on an estimated deceleration predicted for the host vehicle, and a controller configured to apply a different braking force to at least one left wheel and at least one right wheel of the host vehicle based on the target yaw moment computed by said yaw moment computing device.
