The invention discloses a road condition pre-identifying system based on Internet of Things and suitable for vehicle suspension control. The system is composed of a vehicle terminal and a server. The vehicle terminal includes a GPS module, a road information collecting module, a vehicle information module, an ECU and a vehicle control module. The server is composed of an information exchange module, a database and an information processing module. Road information collected by vehicles moving on a road ahead is obtained through the Internet of Things and the required road condition information is collected and uploaded to a server through the vehicle terminal, so that necessary data including front road information and the like is sent to a control part of a vehicle suspension. A road condition identification result is obtained through computation by the server based on a large amount of uploaded data. The identification result in the server is sent to a target vehicle before the target vehicle reaches a target area. Therefore, a function of pre-identifying front road condition is realized and inevitable hysteretic nature of the suspension control system is improved, so that vehicle suspension control is enhanced.
