In at least one possible implementation manner, the method further includes: and when the front liquid level signal is smaller than the rear liquid level signal, the rear liquid level signal is used for indicating value display of the fuel gauge.
In at least one possible implementation manner, the oil supply from the front part of the oil tank or the oil supply from the rear part of the oil tank is switched by triggering the action of reversing valves respectively connected with the front oil outlet and the rear oil outlet.
In at least one possible implementation manner, the method further includes: and continuously collecting the attitude angle of the whole vehicle, and deciding to supply oil from the front part of the oil tank or supply oil from the rear part of the oil tank according to the attitude angle of the whole vehicle.
The design concept of the invention is that the oil height of the front part and the rear part in the oil tank is judged by detecting two oil signals at the front and the rear of the oil tank, and the fuel oil is sucked from the preset oil outlet at the position with higher liquid level and is supplied to the engine, so that the problem of fuel oil supply of the vehicle during ascending and descending is thoroughly solved, the vehicle body can be ensured to smoothly provide sufficient fuel oil during ascending and descending, flameout caused by air suction is avoided, and the normal work of the engine is ensured.
Furthermore, the read oil signals can be switched in an oil meter circuit through a relay and other devices, so that the oil can be correctly displayed when the vehicle body is in an inclined state.
Furthermore, on the basis of the mode, the front and rear oil supply modes of the oil tank can be directly determined through the attitude angle of the whole vehicle.
