Vehicle speed limiting device, vehicle speed limiting method, and vehicle speed limiting program
A vehicle speed limiting device includes a control device with first and second speed limiting functions, and a first cancel function for disabling the first speed limiting function when a first condition is satisfied and the vehicle speed matches a first speed. The control device has a first cancel function canceling the second speed limiting function when an elapsed time from a first time at which the first speed limiting function is disabled by the first cancel function to a second time when the vehicle speed reaches a second speed lower than a predetermined threshold and the first condition is satisfied at the second time; or a second cancel function for disabling the second speed limiting function when a difference between the first and second speeds is smaller than a predetermined threshold and the first condition is satisfied at the second time after the first speed limiting function is disabled.
