Lane departure prevention apparatus
First Claim
1. A lane departure prevention apparatus comprising:
- a system operating-switch to selectively turn the lane departure prevention apparatus between an OFF position corresponding to a non-operating state, in which lane departure avoidance of a host vehicle will not be performed even though the host vehicle is departing from a driving lane, and an ON position corresponding to an operable state in which lane departure avoidance is performed by a braking control operation for avoiding lane departure of the host vehicle from the driving lane when the host vehicle is tending to depart from the driving lane, based on a driver'"'"'s selection of the system operating-switch;
a driver condition detection section configured to detect that a driver condition tending to indicate a driver may not perceive that the host vehicle is tending toward lane departure; and
a lane departure avoidance control section configured to forcibly switch from the non-operating state to the operable state, when the non-operating state is selected by the system operating-switch being in the OFF position and when the driver condition detection section detects that the driver condition is tending to indicate that the driver may not perceive that the host vehicle is tending toward lane departure.

Abstract
A lane departure prevention apparatus is configured to avoid lane departure even when the driver is not focused on driving operations, in a state in which the system-operating switch is OFF. The lane departure prevention apparatus has a driver condition detection section or device for detecting that the condition of the driver which is a condition in which the driver cannot perceive that the host vehicle is tending toward departure, and a lane departure avoidance control device for setting the braking control for avoiding departure in an operable state when the system-operating switch for the driver to instruct the operation of control braking for avoiding the lane departure is OFF, the braking control for avoiding departure is OFF, and the driver condition detection section or device has detected that the condition of the driver is a condition in which the driver cannot perceive that the host vehicle is tending toward departure.

13. A lane departure prevention apparatus comprising:
-
lane departure avoidance control activation means for selectively turning the lane departure prevention apparatus between an OFF position corresponding to non-operating state, in which lane departure avoidance of a host vehicle will not be performed even though the host vehicle is departing from a driving lane, and an ON position corresponding to an operable state in which departure avoidance is performed by an automatic vehicle control operation for avoiding lane departure of the host vehicle from the driving lane when the host vehicle is tending to depart from the driving lane, based on a driver'"'"'s selection of the lane departure avoidance control activation means; driver condition detection means for detecting that a driver condition tending to indicate a driver may not perceive that the host vehicle is tending toward lane departure; and lane departure avoidance control means for forcibly switching from the non-operating state to the operable state, when the non-operating state is selected by the lane departure avoidance control activation means being in the OFF position and when the driver condition detection means detects that the driver condition is tending to indicate that the driver may not perceive that the host vehicle is tending toward lane departure.

14. A lane departure prevention apparatus comprising:
-
a system operating-switch to selectively turn the lane departure prevention apparatus between an OFF position corresponding to a non-operating state and an ON position corresponding to an operable state of an automatic vehicle control operation for avoiding lane departure of a host vehicle from a driving lane when the host vehicle is tending to depart from the driving lane based on a driver'"'"'s selection of the system operating-switch, in which the automatic vehicle control operation is not performed when the non-operating state is selected by the system operating-switch being in the OFF position even though the host vehicle is tending to depart from the driving lane; a driver condition detection section configured to detect that a driver condition tending to indicate a driver may not perceive that the host vehicle is tending toward lane departure; and a lane departure avoidance control section configured to forcibly switch from the non-operating state to the operable state, when the non-operating state is selected by the system operating-switch being in the OFF position and when the driver condition detection section detects that the driver condition is tending to indicate that the driver may not perceive that the host vehicle is tending toward lane departure. - View Dependent Claims (15, 16, 17, 18, 19)
