A travel control apparatus for a vehicle includes: a travel environment information acquisition unit that acquires travel environment information on a travel environment where the vehicle travels; a travel information detector that detects travel information on the vehicle; and an overtaking controller that detects an overtaking target vehicle ahead of the vehicle in an identical travel lane on the basis of the travel environment information and the travel information, and overtakes the overtaking target vehicle using automatic driving control. When failures are detected in relation to the travel environment information acquisition and in a steering system of the vehicle during the overtaking control, the overtaking controller modifies the overtaking control by activating required substitute control in accordance with the travel environment information obtained most recently before detecting the travel environment information acquisition failure, information on the overtaking target vehicle, the travel information, and conditions during the overtaking control. |
