An autonomous driving control apparatus executes an autonomous driving control of a vehicle. The autonomous driving control apparatus includes: a first determination unit configured to determine whether the autonomous driving control can be engaged or not; an autonomous driving control engage trigger input unit; a triggered engage mode configured to engage the autonomous driving control when an autonomous driving control engage trigger is input by a driver to the autonomous driving control engage trigger input unit after the first determination unit determines that the autonomous driving control can be engaged; an automatic engage mode configured to automatically engage the autonomous driving control when the first determination unit determines that the autonomous driving control can be engaged; and a switching unit configured to switch between the triggered engage mode and the automatic engage mode.
