The invention discloses an electric carrying equipment drive-by-wire chassis multi-domain collaborative anti-rollover control method, which comprises the following steps of: 1, constructing a rollover risk assessment and control strategy selection method, and calculating key parameters such as yaw velocity and lateral acceleration of a vehicle in real time; step 2, based on the rollover risk index model and the rollover critical threshold in the step 1, establishing a multi-domain collaborative rollover prevention control model, and performing collaborative scheduling on independent steering, hub motor differential steering and an ESP brake control system; step 3, based on the multi-domain collaborative anti-rollover control model in the step 2; and 4, based on the priority dynamic allocation and control strategy execution result in the step 3, the central control unit coordinates the complex interaction relationship among the subsystems by using a fuzzy logic control algorithm. The invention provides a reliable control strategy priority and use frequency method, and provides a more reliable anti-rollover solution for the electric carrying equipment under a complex dynamic working condition.
