The invention provides an economical type transverse stability control method for a distributed-drive electric vehicle, and belongs to the technical field of vehicle control. The transverse stabilitycontrol method constitutes a kinetic model of an AFS and DYC integrated system containing economy coordination factors I, optimizes a proportion between an additional yawing moment and the AFS system,and improves work efficiency of a hub motor, thus improving economical indexes of the distributed-drive electric vehicle. The method further designs a self-trigger type model predicating control scheme based on an AMHE and NEA mode switching strategy, reduces influences, on AFS and DYC integrated control effect, by disturbance, and improves accuracy of vehicle lateral stability control on the premise of guaranteeing real-time property of the control system.
