The invention provides an auxiliary engine lubricating control method and device. The method comprises the steps that under the situation that an engine controller is in a power-on state, whether thefirst current electric quantity of a battery is in the preset electric quantity allowed range or not is judged; if it is judged that the first current electric quantity of the battery is in the presetelectric quantity allowed range, whether a starter is in a non-start state or not and whether the current rotation speed of an engine is smaller than the rotation speed threshold value or not are judged; if the starter is in the non-start state and/or the current rotation speed is smaller than the rotation speed threshold value, a motor oil pump is controlled to conduct the pre-lubrication operation on the basis of the running state of an engine oil pressure sensor and the current work time duration of the motor oil pump. According to the disclosed method, the pre-lubricating degree can be effectively controlled by utilizing the engine controller state, the battery electric quantity, the starter state, the engine rotation speed, the engine oil pressure sensor state and the motor oil pumpwork duration, and accordingly the problem about insufficient lubricating or electric energy waste due to long-time lubricating is relieved or even solved.
