VEHICLE DRIVE ASSIST APPARATUS

A vehicle drive assist apparatus for a vehicle includes a surrounding-condition-information acquiring unit that acquires surrounding condition information, a vehicle-state-information acquiring unit that acquires vehicle state information, a traveling control processor that executes traveling control in accordance with traffic lane designation, a DDI detector, and a control switch. The DDI detector detects a DDI in a front region of the vehicle on the basis of the surrounding condition information and determines whether the vehicle is entering or exiting from the DDI on the basis of the surrounding condition information and the vehicle state information. The control switch switches the traveling control from standard traveling control to non-standard traveling control when the vehicle entering the DDI is detected, and from the non-standard traveling control to the standard traveling control when the vehicle exiting from the DDI is detected on the basis of the result of the DDI determination.
