1. A lane departure prevention apparatus comprising:
- a holding state detection section configured to detect whether a driver is holding the steering wheel steady;
a warning output section configured to output a warning;
a lane departure tendency detection section configured to detect a lane departure tendency of a host vehicle from its driving lane; and
a lane departure-avoidance control section configured to output the warning from the warning output section prior to performing lane departure avoidance braking control when the lane departure tendency detection section detects the lane departure tendency and the holding state detection section detects that the driver is not holding the steering wheel steady.

Abstract
A lane departure prevention apparatus is provided to improve safety while preventing lane departure. The lane departure prevention apparatus determines whether or not the driver is holding the steering wheel steady, determines whether or not the host vehicle has a tendency to depart from its driving lane, and, on the basis of these determination results, outputs a warning and performs braking control for avoiding the lane departure of the host vehicle when the host vehicle has a tendency to depart from its driving lane, and the driver is not holding the steering wheel steady.
