Abstract
Provided is a vehicle control device configured to: generate a target trajectory of a vehicle; and determine whether change in speed of a target steering angle in a first period is equal to or larger than a first threshold value and whether change in speed of the target steering angle in a second period is equal to or larger than a second threshold value; and change, in a case where the driving mode of the vehicle is a second driving mode, the driving mode of the vehicle to a first driving mode when the change in speed of the target steering angle in the first period is determined to be equal to or larger than the first threshold value or when the change in speed of the target steering angle in the second period is determined to be equal to or larger than the second threshold value.
