The invention provides a vehicle condition sensing system based on roadside LED equipment and Internet of Vehicles. The vehicle condition sensing system comprises the roadside LED equipment and a vehicle-mounted terminal, the roadside LED equipment comprises an LED unit, an LED drive circuit, an encoder, a microprocessor and a radar detector; the radar detector is used for detecting road surface vehicle condition information, and the microprocessor sends vehicle condition data to the encoder to be encoded into a control signal of the LED drive circuit; the LED drive circuit drives the LED unit to emit a light signal carrying road surface vehicle condition information according to the control signal; the vehicle-mounted terminal comprises an optical signal receiving circuit, a decoder, a processor and a communication module; wherein the optical signal receiving circuit is used for receiving an optical signal emitted by roadside LED equipment and converting the optical signal into an electric signal; the decoder decodes the converted electric signals to obtain road surface vehicle condition information, and then the road surface vehicle condition information is broadcasted to a vehicle network where the vehicle is located through the communication module. According to the invention, the road condition information collected in a local region can be quickly transmitted to the vehicle, and the feedback speed of the vehicle condition information is greatly improved.
