Abstract

An electric vehicle road speed limit control system comprises a detection unit and a speed change unit. When detecting that an electric vehicle enters a speed limit road section, the detection unit monitors the speed of the electric vehicle in the whole road section; if it is monitored that the electric vehicle travels at overspeed, a signal transmission module sends a limited speed to a signal receiving module; when receiving a speed signal received by the signal receiving module, a speed control module controls the electric vehicle at overspeed to reduce the speed to the limited speed; if it is monitored that the electric vehicle does not travel at overspeed, the speed control module does not execute speed regulation. The control system enables the electric vehicle to travel safely on the speed limit road section, and therefore the accident rate of electric vehicles can be effectively reduced.
