Vehicle speed limiting device

A vehicle speed limiting device which acquires a speed limit of a vehicle in a run way, sets up upper-limit vehicle speed that is an upper limit of vehicle speed based on said acquired speed limit, and controls driving force so that said vehicle speed does not exceed said upper-limit vehicle speed, comprising:

• an upper-limit vehicle speed change operation unit comprising at least one of a lever or a plurality of buttons, the upper-limit vehicle speed change operation unit configured to:
• perform, in response to a driver's first operation to the upper-limit vehicle speed change operation unit during a first mode, a first function that changes said upper-limit vehicle speed to a first desired value,
• perform, in response to a driver's second operation to the upper-limit vehicle speed change operation unit during the first mode, a second function that changes said upper-limit vehicle speed to a second desired value,
• perform, in response to the driver's first operation to the upper-limit vehicle speed change operation unit during a second mode, a third function that accepts a change of said speed limit, and
• perform, in response to the driver's second operation to the upper-limit vehicle speed change operation unit during the second mode, a fourth function that rejects the change of said speed limit,
• a controller that is configured to:
• temporarily switch functions of said upper-limit vehicle speed change operation unit from the first and second functions to the third and fourth functions when switching from the first mode to the second mode at a timing when said acquired speed limit is switched to a new speed limit, and
• prohibits switching of the function of said upper-limit vehicle speed change operation unit from said first and second functions to said third and fourth functions, even if said acquired speed limit is switched to the new speed limit, until a predetermined prohibition release timing comes after said upper-limit vehicle speed change operation unit operates with said first or second functions.
