When it is detected that a speed limit is changed, an upper-limit vehicle speed setting ECU temporarily switches a control mode from a normal mode to an inquiry mode. An ASL operation unit serves a function for a change operation of upper-limit vehicle speed in the normal mode, and serves a function for a reply operation about whether the speed limit is accepted in the inquiry mode. When the ASL operation unit is operated in the normal mode, the upper-limit vehicle speed setting ECU does not switch the control mode to the inquiry mode, even if a change of a speed limit is detected, until a certain period of time (a certain period during which a mode switching prohibition period is set) has passed since the operation. ## Claims ### Claim 1 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 that is an operation unit for changing said upper-limit vehicle speed to a desired value in accordance with a driver's operation, a function switching means which temporarily switches function of said upper-limit vehicle speed change operation unit from a first function that changes said upper-limit vehicle speed to the desired value in accordance with a driver's operation to a second function that replies whether a change of said speed limit is accepted in accordance with a driver's operation, at a timing when said acquired speed limit is switched, and a function switching prohibition means which prohibits the function of said upper-limit vehicle speed change operation unit from being switched to said second function, even if said acquired speed limit is switched, until a predetermined prohibition release timing comes after said upper-limit vehicle speed change operation unit operates with said first function. ### Claim 2 (depends on 1) The vehicle speed limiting device according to claim 1, wherein: said predetermined prohibition release timing comes when elapsed time after said upper-limit vehicle speed change operation unit operates with said first function reaches predetermined setup time. ### Claim 3 (depends on 1) The vehicle speed limiting device according to claim 1, wherein: said predetermined prohibition release timing comes when running distance of the vehicle after said upper-limit vehicle speed change operation unit operates with said first function reaches predetermined setup distance. ### Claim 4 (depends on 1) The vehicle speed limiting device according to claim 1, wherein: said predetermined prohibition release timing comes when elapsed time after said upper-limit vehicle speed change operation unit operates with said first function reaches predetermined setup time or when running distance of the vehicle after said upper-limit vehicle speed change operation unit operates with said first function reaches predetermined setup distance, whichever comes first. ### Claim 5 (depends on 1) The vehicle speed limiting device according to claim 1, further comprising: a display means which displays a first display screen showing an upper-limit vehicle speed at present during a period when said upper-limit vehicle speed change operation unit operates with the first function, and displays a second display screen showing said switched new speed limit and a reply operation method about whether a change of said speed limit is accepted, in addition to said upper-limit vehicle speed, during a period when said upper-limit vehicle speed change operation unit operates with the second function. ### Claim 6 (depends on 5) The vehicle speed limiting device according to claim 5, wherein: said display means displays only an operation method for accepting a change of said speed limit as the reply operation method displayed in said second display screen, and said vehicle speed limiting device further comprises an automatic reply receipt means which judges that a driver rejects to accept a change of said speed limit when said upper-limit vehicle speed change operation unit is not operated during a period when said upper-limit vehicle speed change operation unit operates with said second function. ### Claim 7 (depends on 1) The vehicle speed limiting device according to claim 1, further comprising: a functional reversion means which reverts the function of said upper-limit vehicle speed change operation unit from said second function to said first function, at a timing when said upper-limit vehicle speed change operation unit operates with said second function. ### Claim 8 (depends on 2) The vehicle speed limiting device according to claim 2, further comprising: a display means which displays a first display screen showing an upper-limit vehicle speed at present during a period when said upper-limit vehicle speed change operation unit operates with the first function, and displays a second display screen showing said switched new speed limit and a reply operation method about whether a change of said speed limit is accepted, in addition to said upper-limit vehicle speed, during a period when said upper-limit vehicle speed change operation unit operates with the second function. ### Claim 9 (depends on 3) The vehicle speed limiting device according to claim 3, further comprising: a display means which displays a first display screen showing an upper-limit vehicle speed at present during a period when said upper-limit vehicle speed change operation unit operates with the first function, and displays a second display screen showing said switched new speed limit and a reply operation method about whether a change of said speed limit is accepted, in addition to said upper-limit vehicle speed, during a period when said upper-limit vehicle speed change operation unit operates with the second function. ### Claim 10 (depends on 4) The vehicle speed limiting device according to claim 4, further comprising: a display means which displays a first display screen showing an upper-limit vehicle speed at present during a period when said upper-limit vehicle speed change operation unit operates with the first function, and displays a second display screen showing said switched new speed limit and a reply operation method about whether a change of said speed limit is accepted, in addition to said upper-limit vehicle speed, during a period when said upper-limit vehicle speed change operation unit operates with the second function.
