[0002] At present, long-distance heavy trucks have large fuel tanks and long lengths due to the need for cruising range. When the vehicle is traveling on uphill or downhill roads, the inclination of the fuel tank will cause the fuel to gather on one side of the fuel tank.

In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0032] At present, long-distance heavy trucks have large fuel tanks and long lengths due to the need for cruising range. When the vehicle is traveling on uphill or downhill roads, the inclination of the fuel tank will cause the fuel to gather on one side of the fuel tank. If the fuel level in the fuel tank is too low at this time, the fuel tank oil inlet will be arranged forward or backward, which will cause the engine to fail to absorb fuel and cause the engine to stall, posing a great threat to the driver's life and property safety.

[0033] In the related art, the fuel tank's oil intake port is arranged in the middle of the fuel tank, but this still causes the fuel to gather on one side of the fuel tank when the vehicle goes uphill or downhill, resulting in the engine being unable to absorb the fuel, making most of the fuel at the bottom of the tank unusable.

[0034] In response to the above problems, an embodiment of the present application provides a control method for a fuel supply system, which can reduce the problem of fuel gathering on one side of the fuel tank when the vehicle goes uphill or downhill, resulting in the engine being unable to absorb fuel, thereby improving fuel utilization efficiency.

[0035] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0036] Figure 1 It is a schematic flow chart of the control of the oil supply system shown in the embodiment of the present application.

[0037] See also Figure 1 , a control method for a fuel supply system, comprising:

[0038] S110: Acquire a first liquid level of a subsidiary fuel tank of the vehicle, a fuel temperature of the subsidiary fuel tank, and a second liquid level of a main fuel tank.

[0039] See also Figure 3 , Figure 4 , Figure 5Specifically, the fuel supply system includes an auxiliary fuel tank 1 and a main fuel tank 2. The auxiliary fuel tank 1 and the main fuel tank 2 can be made of plastic. The auxiliary fuel tank 1 at least includes a first liquid level sensor, a temperature sensor, an electric pump 5 and a fuel filter 4. The volume of the auxiliary fuel tank 1 can be 20L to 50L. The auxiliary fuel tank 1 is provided with an auxiliary fuel tank filling port 101 at the top, and the staff can fill the auxiliary fuel tank 1 with fuel through the auxiliary fuel tank filling port 101. The auxiliary fuel tank 1 is provided with an auxiliary fuel tank drain port 102 at the bottom, which can be used by the staff to drain the fuel in the auxiliary fuel tank 1 from the drain port to improve the utilization rate of the fuel. The first liquid level sensor of the auxiliary fuel tank The level sensor is arranged inside the auxiliary tank 1, and can be used to monitor the liquid level of the fuel in the auxiliary tank 1, and send the fuel level data to the control unit in real time; the temperature sensor can be used to monitor the temperature of the fuel in the auxiliary tank 1 in real time, the fuel filter 4 is arranged inside the auxiliary tank 1, and the fuel filter 4 can filter the refluxed fuel or the fuel transmitted by the main tank 2, and the auxiliary tank 1 is also provided with a fuel outlet 103 at the bottom, and the fuel filter 4 is connected to the fuel outlet 103 through a pipeline, and an oil inlet pipeline is connected between the auxiliary tank 2 and the engine 3, and the fuel can enter the engine 3 from the auxiliary tank through the oil inlet pipeline. The main tank 2 includes at least a second level sensor, and the second level sensor can be used to monitor the liquid level height of the fuel in the main tank 2, and an oil guide pipeline is connected between the auxiliary tank 1 and the main tank 2, and the fuel can be transmitted between the main tank 2 and the auxiliary tank 1 through the oil guide pipeline.

[0040] Specifically, a plurality of one-way valves and TRV valves are also provided in the auxiliary fuel tank 1. The one-way valves and TRV valves are provided on the oil guide pipe between the main fuel tank 2 and the auxiliary fuel tank 1. The fuel can pass through the oil guide pipe, through the one-way valve, TRV valve, fuel filter 4, one-way valve, and electric pump, and enter the auxiliary fuel tank 1; a one-way valve and a steering valve are provided on the oil inlet pipe, and the fuel can pass through the oil inlet pipe, from the auxiliary fuel tank, through the electric pump 5, the one-way valve, and the steering valve, and enter the engine 3; when a problem occurs with the vehicle, such as a failure of the electric pump 5 or the liquid level sensor, and the engine 3 cannot be supplied with fuel in time, a conversion valve is provided on the oil inlet pipe, and the driver can operate the conversion valve to directly supply fuel from the main fuel tank 2 through the oil inlet pipe, and allow the oil to enter the engine 3 through the oil inlet pipe.

[0041] S120: Based on at least one of the first liquid level, the fuel temperature, and the second liquid level, the working state of the electric pump is controlled so that the fuel is transferred between the auxiliary fuel tank and the main fuel tank through the oil guide line, and the fuel is transferred between the auxiliary fuel tank and the engine through the oil inlet line. The working states include forward rotation of the electric pump, reverse rotation of the electric pump, and stop of the electric pump.

[0042] Specifically, the working state of the electric pump can be controlled according to the first liquid level in the auxiliary fuel tank, the fuel temperature in the auxiliary fuel tank and the second liquid level in the main fuel tank. The working state of the electric pump can be controlled according to the first liquid level and the second liquid level, or according to the fuel temperature. There is no limitation here. The working state of the electric pump can include forward rotation of the electric pump, reverse rotation of the electric pump and stop of the electric pump. When the electric pump is running forward, the fuel enters the auxiliary fuel tank from the main fuel tank through the oil guide line between the main fuel tank and the auxiliary fuel tank; when the electric pump is reversed, the fuel can enter the engine from the auxiliary fuel tank through the oil inlet line.

[0043] In one possible implementation, when the vehicle is in a driving state, it is determined whether the first liquid level of the auxiliary fuel tank is less than a first threshold value; if so, it is determined whether the second liquid level of the main fuel tank is higher than the first threshold value; if so, the electric pump is controlled to rotate forward so that the fuel passes through the fuel filter and the oil guide line from the main fuel tank into the auxiliary fuel tank until the first liquid level is greater than the second threshold value, and the electric pump is controlled to stop.

[0044] Specifically, when the vehicle is in a driving state, such as moving forward, turning, etc., especially when the vehicle is driving on uphill and downhill roads, it is possible to monitor whether the first liquid level in the auxiliary fuel tank is less than a first threshold value. The first threshold value can be set to 20%, 10%, etc. of the total liquid level in the auxiliary fuel tank, and there is no restriction here; if the first liquid level is less than the first threshold value, it is determined whether the second liquid level in the main fuel tank is greater than the first threshold value. If the second liquid level in the main fuel tank is greater than the first threshold value, the control unit can control the electric pump to forward the fuel so that the fuel enters the auxiliary fuel tank from the main fuel tank through the oil guide line. When the liquid level in the auxiliary fuel tank reaches a certain height, the control unit can control the electric pump to stop, and the main fuel tank stops supplying oil to the auxiliary fuel tank.

[0045] In one possible implementation, if the vehicle is in a driving state, it is determined whether the first liquid level of the auxiliary fuel tank is greater than a first threshold value; if so, the electric pump is controlled to reverse so that the fuel enters the engine from the auxiliary fuel tank through the oil inlet pipe, and the fuel enters the fuel filter from the engine through the oil return pipe until the first liquid level of the auxiliary fuel tank is less than the first threshold value.

[0046] Specifically, it can be determined whether the first liquid level of the auxiliary fuel tank is greater than a first threshold value. If the first liquid level is greater than the threshold value, it indicates that the amount of fuel in the auxiliary fuel tank is relatively large. The control unit controls the electric pump to reverse, so that the fuel in the auxiliary fuel tank can enter the engine through the oil inlet pipe, and the engine can allow the unused fuel to enter the auxiliary fuel tank through the oil return pipe. A TRV valve is provided on the oil return pipe. If the temperature of the oil is lower than the set value of the TRV valve, the oil passes through the fuel filter and then enters the auxiliary fuel tank. If the temperature of the oil is higher than the set value of the TRV valve, the oil can directly enter the auxiliary fuel tank without passing through the fuel filter. A heater is also provided in the auxiliary fuel tank to heat the fuel.

[0047] In one possible implementation, when the vehicle is in motion, it is determined whether the fuel temperature in the auxiliary fuel tank is greater than a preset temperature; if so, the electric pump is controlled to rotate forward so that the fuel flows from the main fuel tank into the auxiliary fuel tank through the oil guide line until the fuel temperature is lower than the preset temperature.

[0048] Specifically, during the driving of the vehicle, the temperature sensor in the auxiliary fuel tank monitors the temperature of the fuel in real time. If the temperature of the fuel is greater than the preset temperature, such as 70°C, it indicates that the temperature of the fuel in the auxiliary fuel tank is too high. If the fuel at this temperature is input into the engine, it will cause damage to the engine. The control unit can control the electric pump to forward the fuel in the main fuel tank into the auxiliary fuel tank through the oil guide line. The temperature of the fuel in the main fuel tank is generally lower, thereby reducing the temperature of the fuel in the auxiliary fuel tank.

[0049] In a possible implementation, if the fuel temperature of the auxiliary fuel tank is greater than a preset temperature and the first liquid level of the auxiliary fuel tank is greater than a third threshold, the fuel is controlled to flow from the auxiliary fuel tank into the main fuel tank through the overflow line until the fuel temperature is lower than the preset temperature.

[0050] Specifically, when there is too much fuel in the auxiliary fuel tank, but the fuel temperature in the auxiliary fuel tank is still higher than the preset temperature, the fuel in the auxiliary fuel tank can enter the main fuel tank through the overflow pipeline to receive the fuel transmitted from the main fuel tank until the fuel temperature in the auxiliary fuel tank is lower than the preset temperature. The control unit can control the electric pump to stop, so that the main fuel tank stops delivering fuel to the auxiliary fuel tank.

[0051] In a possible implementation, when the vehicle is in driving state, it is determined whether at least one of the second liquid level of the main fuel tank and the first liquid level of the auxiliary fuel tank is less than a fourth threshold; if so, the vehicle issues a warning prompt.

[0052] Specifically, if the second liquid level in the main fuel tank or the first liquid level in the auxiliary fuel tank is less than a fourth threshold value, the fourth threshold value may be 5%, etc., indicating that the fuel levels of the two tanks are too low at this time, an early warning may be issued to the operator, indicating that there is too little fuel in the vehicle's fuel tank, for example, through voice prompts, display screens, etc.

[0053] In one possible implementation, if the engine is turned off, it is determined whether the first liquid level of the auxiliary fuel tank is greater than a fourth threshold value; if so, the electric pump is controlled to rotate forward so that the fuel enters the auxiliary fuel tank from the main fuel tank through the oil guide line until the first liquid level is greater than the fourth threshold value; if the first liquid level is greater than the fourth threshold value, the electric pump is controlled to stop.

[0054] Specifically, when the vehicle is in a parked state, the vehicle starts normally but the engine stops, and it can be determined whether the first liquid level in the auxiliary fuel tank is greater than a fourth threshold value. If the first liquid level in the auxiliary fuel tank is greater than the fourth threshold value, the electric pump can be controlled to rotate forward so that the fuel in the main fuel tank can enter the auxiliary fuel tank through the oil guide line to replenish the amount of fuel in the auxiliary fuel tank. When the fuel level in the auxiliary fuel tank is too high, when the first liquid level is greater than the fourth threshold value, the electric pump is controlled to stop to avoid excessive fuel in the auxiliary fuel tank and overflow.

[0055] Specifically, before starting the vehicle, the operator can manually control the electric pump to reverse, so that the fuel in the auxiliary fuel tank enters the engine through the fuel inlet pipe, thereby shortening the engine starting time.

[0056] Specifically, the second liquid level sensor in the main fuel tank can send the liquid level data to the vehicle's dashboard in real time. The fuel level in the main fuel tank can actually be monitored in real time through the dashboard. When the second liquid level in the main fuel tank is too low, the vehicle can issue an alarm to prompt the driver to refuel the main fuel tank.

[0057] The fuel supply system of the present application includes an auxiliary fuel tank and a main fuel tank, the auxiliary fuel tank includes at least a first liquid level sensor, a temperature sensor, an electric pump and a fuel filter, the main fuel tank includes at least a second liquid level sensor, an oil guide line is connected between the auxiliary fuel tank and the main fuel tank, and an oil inlet line is connected between the auxiliary fuel tank and the engine, and a control method includes: obtaining a first liquid level of the auxiliary fuel tank of the vehicle, a fuel temperature of the auxiliary fuel tank, and a second liquid level of the main fuel tank; according to at least one of the first liquid level, the fuel temperature, and the second liquid level, controlling the working state of the electric pump so that the fuel is transmitted between the auxiliary fuel tank and the main fuel tank through the oil guide line, and the fuel is transmitted between the auxiliary fuel tank and the engine through the oil inlet line, and the working state includes forward rotation of the electric pump, reverse rotation of the electric pump, and stoppage of the electric pump, which can reduce the problem of fuel gathering on one side of the fuel tank when the vehicle goes uphill and downhill, resulting in the engine being unable to absorb oil, thereby improving fuel use efficiency.
