Automated driving control system

An automated driving control system, comprising:

• an operation input device configured to accept a first operation and a second operation performed by an operator while a vehicle is traveling in an automated driving mode;
• and
• a speed control device configured to control speed of the vehicle in accordance with the first operation and the second operation, wherein:
• the speed control device executes
• continuous deceleration control for decelerating the vehicle over a period of time that the first operation is effective, and
• speed setting change control for selecting, upon reception of the second operation, one set speed out of a plurality of set speeds that are set in advance and changing a target speed of the vehicle to the selected set speed;
• and
• when, upon completion of the continuous deceleration control, a deceleration completion speed, which is a speed at completion of the continuous deceleration control, is equal to or above a slowest set speed among the set speeds, the speed control device is configured to set as a new target speed the set speed that is equal to or below the deceleration completion speed and that is closest to the deceleration completion speed.
