The invention provides a vehicle electro-hydraulic suspension control method based on event triggering and a finite frequency domain. The vehicle electro-hydraulic suspension control method comprises the following steps that S1, a quarter vehicle electro-hydraulic suspension system simulation model is constructed; s2, initializing an initialization parameter, an initial state and an initial control signal of an electro-hydraulic actuator in the quarter vehicle electro-hydraulic suspension system simulation model; s3, acquiring state information x of the electro-hydraulic suspension system in real time; s4, calculating a control gain K and an event triggering weight matrix phi which meet constraint conditions; s5, outputting the state information of the electro-hydraulic suspension system meeting the event triggering condition; s6, calculating target force Fad (ts) under the event triggering condition; and S7, the main power tracking controller drives the electro-hydraulic actuator to act. By means of the method, the suspension control system can be more robust under excitation of different road surfaces, the riding comfort of the vehicle can be improved, and the communication load can be reduced.
