Abstract

A speed control device can execute continuous deceleration control and speed setting change control. In the continuous deceleration control, a vehicle is decelerated over a period of time that a first operation is effective. In the speed setting change control, upon reception of a second operation, one set speed is selected out of a plurality of set speeds that are set in advance, and a target speed of the vehicle is changed to the selected set speed. When 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.

First claim

What is claimed is:

1. An automated driving control system, comprising:
a button configured to accept a first operation and a second operation performed by an operator while a vehicle is traveling in an automated driving mode, the first operation is a long-press operation for continuously pressing the button for more than a prescribed threshold period; 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;

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; and
the speed control device completes the deceleration of the vehicle immediately after releasing the pressing of the button in the first operation.

2. The automated driving control system according to claim 1 , wherein when the deceleration completion speed is less than the slowest set speed, the speed control device is configured to set the slowest set speed as the new target speed.

3. The automated driving control system according to claim 1 , wherein:
the second operation is a short-press operation for continuously pressing the button for the threshold period or less; and
the speed control device is configured to change the target speed when the short-press operation on the button is detected.
