The invention discloses a multi-working-condition suspension previewing system based on intelligent networking and a control method for the multi-working-condition suspension previewing system. The multi-working-condition suspension previewing system comprises a database unit, a sensor unit, an ECU, a vehicle working condition adjusting module and an expert system. Through the intelligent networking technology, the road condition in front of a vehicle can be previewed, and the vehicle is intelligently switched among a comfort working condition, a standard working condition and an energy storage working condition. Under the comfort working condition, the parameters of a suspension can be automatically changed, so that the suspension is suitable for the current road condition; and under the energy storage working condition, energy can be recycled to supply power to vehicle-mounted electrical equipment, and therefore the purposes of energy conservation, emission reduction and environment-friendly travel are achieved. Meanwhile, information sharing is achieved through the system, and the accuracy and the validity of data in a database are guaranteed. By the adoption of the system, the taking comfort and the operation stability of the vehicle can be effectively improved, the requirements for the sensing distance and the accuracy of a sensor and the performance of a vehicle-mounted computer are low, practicality is high, and the system has the important significance in development of medium-high-grade vehicles and intelligent transportation.
