Lane departure prevention apparatus

A lane departure prevention apparatus is configured for improving safety of a host vehicle (100) while preventing lane departure. The lane departure prevention apparatus basically comprises a lane departure tendency determining section (step S4), a running condition determining section (step S3) and a braking force control section (step S9). The lane departure tendency determining section (step S4) determines a lane departure tendency of the host vehicle (100) from a driving lane. The running condition determining section (step S3) determines a running condition of the host vehicle (100). The braking force control section (step S9) controls a braking force to selectively produce at least one of a yaw moment on the host vehicle (100) in accordance with the lane departure tendency of the host vehicle (100) to avoid departure of the host vehicle (100) from the driving lane, and a deceleration on the host vehicle (100) in accordance with the running condition of the host vehicle (100).
