A driving control apparatus of the present invention has a driving road
keeping device for providing a torque to a steering mechanism so as to
keep a vehicle traveling at a predetermined position on a driving road; a
driving road departure warning device for issuing a warning of a
departure from the driving road on the basis of a position of the vehicle
relative to the driving road; and a setting device for setting a need or
no need for execution of a control of the driving road keeping device or
the driving road departure warning device. Where the setting device sets
a need for execution of the control, the control of the driving road
keeping device is executed when an activation condition of the driving
road keeping device is met and when a cruise control device is active.
Where the setting device sets a need for execution of the control, the
control of the driving road departure warning device is executed when the
activation condition of the driving road keeping device is not met or
when the cruise control device is inactive. According to the present
invention, a lane departure warning function and a lane-keep assist
function are selectively executed in conjunction with
activation/deactivation of the cruise control device and the activation
condition of the driving road keeping device, whereby, even with an
automatic stop of operation of either one of the functions, the other
function can prevent the vehicle from departing from the lane.
