Abstract

A lane departure prevention device includes a control unit that executes lane keeping control (automatic steering of a steering wheel and/or issuing of a warning) when it is determined that a vehicle may move out of a lane. The control unit withholds execution of the lane keeping control until it is determined that a return-to-control condition is satisfied when it is determined that a driver has gone from showing no intention to move out of the lane to showing an intention to move out of the lane to cross a first lane boundary. The control unit continues, when it is determined that the vehicle is approaching a second white line present in a traveling direction with a speed equal to or faster than a reference value, continues withholding the execution of the lane keeping control even when it is determined that the return-to-control condition is satisfied.
