1. A vehicle speed limiting device, comprising:
an operation unit sensor configured to detect an operation mode of an operation unit to be operated when a driver accelerates an own vehicle;
a speed sensor configured to detect a speed of the own vehicle; and
a control device having a first vehicle speed limiting function of controlling any one or both of a drive device and a braking device of the own vehicle such that the speed does not exceed a first speed, a first cancel function of disabling the first vehicle speed limiting function when a first operation unit condition relating to an operation on the operation unit is satisfied in a situation in which the speed of the own vehicle matches the first speed, a second vehicle speed limiting function of controlling any one or both of the drive device and the braking device of the own vehicle such that the speed of the own vehicle does not exceed a second speed higher than the first speed, and a second cancel function of disabling the second vehicle speed limiting function when a second operation unit condition relating to the operation on the operation unit is satisfied in a situation in which the speed of the own vehicle matches the second speed,
wherein the control device has at least one of:
a first forcible cancel function of forcibly disabling the second vehicle speed limiting function when an elapsed time from a first time point at which the first vehicle speed limiting function is disabled through use of the first cancel function to a second time point at which the speed of the own vehicle reaches the second speed is shorter than a predetermined threshold value and the first operation unit condition is satisfied at the second time point; or
a second forcible cancel function of forcibly disabling the second vehicle speed limiting function when a difference between the first speed and the second speed is smaller than a predetermined threshold value and the first operation unit condition is satisfied at the second time point after the first vehicle speed limiting function is disabled through use of the first cancel function.
