Abstract

A lane departure prevention apparatus is configured to conduct a course correction in a lane departure avoidance direction when the controller 8 determines that there is a potential for a vehicle to depart from a driving lane. The controller 8 combines yaw control and deceleration control to conduct departure prevention control to avoid lane departure. The yaw control is not actuated if the opposite direction from the steering direction coincides with the lane departure direction (steps S10 and S11). Preferably, the controller 8 sets the timing of yaw moment and the deceleration of the vehicle on the basis of the acceleration or deceleration of the vehicle, and performs braking control so that these settings are achieved (steps S7 to S9). Preferably, the controller 8 calculates the target yaw moment in the lane departure-avoidance direction on the basis of the running state of the vehicle, and calculates the deceleration amount by taking into account the driver braking operation amount.
