The invention provides a motor-driven vehicle longitudinal and transverse coupling control method and system, and a storage medium. The method comprises the following steps: acquiring a road adhesioncoefficient and a lateral vehicle speed parameter; generating a driving anti-skid control strategy according to the lateral vehicle speed parameter, and performing preliminary distribution of a vehicle longitudinal driving torque; obtaining a target yawing moment according to the road adhesion coefficient and the lateral vehicle speed parameter; and performing longitudinal and transverse couplingcontrol according to the result of the preliminary distribution of the longitudinal driving torque, the driving anti-skid control strategy and the target yawing torque. According to the method, aimingat the longitudinal and transverse coupling characteristics of the vehicle, longitudinal and transverse nonlinearity of the vehicle can be effectively overcome through centralized coordination control and longitudinal and transverse coordination control laws formed by the longitudinal driving torque and the target yawing torque, and a high coupling characteristic of the vehicle is exerted; and the method is simple in implementation mode, small in calculation amount, high in calculation speed, suitable for being used by a real vehicle, capable of achieving a multi-target coordination optimal effect and capable of being widely applied to the technical field of hub motor driving vehicle control.
