The invention discloses an axial and radial coupling magnetic flux motor, a control method, a power control system and a vehicle. The control method comprises the following steps that at least one axial magnetic flux motor and at least one radial magnetic flux motor are separated and coaxially arranged on a rotating shaft in a shell; the actual rotating speed of the rotating shaft is n, and obtaining a working rotating speed demarcation point nc and a transition rotating speed nt; when n is smaller than or equal to nc-nt, the axial magnetic flux motor is set to be in a main driving mode, the radial magnetic flux motor is set to be in a driving mode, an idling mode or a power generation mode, enough torque needed by the load at the actual rotating speed is provided, and the axial magnetic flux motor is always kept in a high-efficiency interval; and when n is greater than or equal to nc + nt, setting the radial magnetic flux motor to be in a main driving mode, setting the axial magnetic flux motor to be in a driving mode, an idling mode or a power generation mode, and providing enough torque required by the load at the actual rotating speed, so that the radial magnetic flux motor is always kept in a high-efficiency interval. The invention has the advantages of small rotational inertia, strong power and certain fault-tolerant capability.
