Abstract

The invention discloses an automatic speed limiting device for electric vehicles based on the Internet of Things, which includes a speed limit code transmitter embedded on a speed limit road sign and a speed control mechanism installed on the electric vehicle. Networked coded receiver for communication with speed limit coded transmitter, speedometer for real-time detection of vehicle speed, PLC module for processing signals and issuing control instructions, and controller for real-time speed regulation of automobile motors according to control instructions , the input end of the PLC module is connected to the output end of the encoding receiver and the speedometer respectively, and the output end of the PLC module is connected to the automobile motor through the controller. The application of the present invention can forcibly decelerate an overspeeding electric vehicle, thereby avoiding the occurrence of traffic accidents caused by the high speed of the vehicle, and providing reliable guarantee for traffic safety.

Description

technical field [0001] The invention relates to an auxiliary facility in traffic management, in particular to a device for limiting the speed of an electric vehicle. Background technique [0002] At present, in the technical lines of various new energy vehicles, zero-pollution vehicles represented by pure electric vehicles have become the main direction for the transformation and development of future automotive energy and power systems. Pure electric vehicles are powered by vehicle-mounted power supplies, drive wheels with electric motors, and meet various requirements of road traffic and safety regulations. However, due to the influence of the driver's control habits, electric vehicles often experience overspeeding during driving, and the driver does not know it, which will invisibly bring harm to the driver, others around the electric vehicle, and road traffic. a great safety hazard. In addition, during the driving of electric vehicles, when passing through the speed-li...
