1. A vehicle equipped with an autonomous driving system that executes speed control that causes an actual speed to follow a target speed, wherein:
the autonomous driving system includes
at least one memory that stores at least one program, and
at least one processor connected to the at least one memory; and
the at least one processor executes, through execution of the at least one program,
a control mode switching process of switching a control mode of the speed control between a first control mode and a second control mode in accordance with a driving condition, the first control mode being a mode in which the actual speed is caused to follow the target speed through active use of a brake, and the second control mode being a mode in which the actual speed is caused to follow the target speed while use of the brake is suppressed,
a notification process of providing a notification to a driver when a speed error between the target speed and the actual speed exceeds a threshold value while the speed control is being executed,
a first threshold value change process of changing the threshold value to a value larger than a value in the first control mode when the control mode is switched from the first control mode to the second control mode, and
a second threshold value change process of changing the threshold value to a value smaller than a value in the second control mode when the control mode is switched from the second control mode to the first control mode.
