The invention relates to a method for controlling a hybrid drive train (10) of a motor vehicle, comprising: - at least one motor member (11, 12) mounted on a first wheel assembly (14); - an electric drive motor (20) mounted on a second wheel assembly (21); - a battery (26); - a device (23) for coupling and decoupling the electric drive motor (20); and - a cooling circuit in which a coolant fluid flows. Said method comprises a step of controlling the device (23) selectively into a locked state or into an unlocked state on the basis of the following thermal criteria: - a temperature of the heat-transfer fluid; - a temperature of the battery; and - a capacity of the cooling circuit to maintain a target temperature of the heat-transfer fluid determined on the basis of an outside temperature and of a speed of the motor vehicle.
