The invention discloses an intelligent vehicle speed-limiting control system and method according to road segments. Speed-limiting values are not pre-set in a server and vehicle-mounted speed-limiting equipment, a speed-limiting fence is established by a remote service terminal according to requirements, reasonable speed-limiting values stored in the server are updated in real time, and therefore the speed-limiting values are adjusted in real time according to actual environmental information such as a road condition. The matching of the speed-limiting fence and a gridding ID is completed automatically by the server, a speed-limiting fence request and execution of accessing a new gridding are completed automatically by the vehicle-mounted speed-limiting equipment, the speed-limiting fence is sent automatically after the server receives the request information of the vehicle-mounted speed-limiting equipment, an on-demand request and the execution of the speed-limiting fence are achieved by the vehicle-mounted speed-limiting equipment, matching work of vehicle-road segment-road path is not needed to operate frequently, and the usability of segmentation speed-limiting function is improved. Calculation of the gridding ID is distributed in the vehicle-mounted speed-limiting equipment to execute rather than concentrated in a cloud terminal, the instantaneity of the system is improved, and the performance requirement of the server is lowered.
