[0026] In the related art, at present, family cars have become an indispensable means of transportation in our daily lives. Common family cars with dual fuel tanks are equipped with two separate switch buttons in the cab, and the corresponding gasoline pumps are controlled by the two separate switch buttons to achieve switching between the dual fuel tanks. However, using the dual switch buttons to switch between the dual fuel tanks is prone to switching failure due to improper operation, which in turn causes the vehicle to malfunction and be unable to drive normally.

[0027] In response to the problems existing in the above-mentioned related technologies, the present application proposes a vehicle dual fuel tank switching method and device, computer storage medium and vehicle, which can at least switch the dual fuel tanks according to the vehicle's operating parameters, thereby reducing the probability of failure due to improper operation to a certain extent.

[0028] Figure 1A schematic flow chart of a dual fuel tank switching method for a vehicle provided according to an embodiment of the present application is shown. The execution subject of the dual fuel tank switching method for a vehicle may be a computing device with computing and processing functions, such as an EMS (Engine Management System) of a vehicle. The dual fuel tank switching method for a vehicle includes steps S101 to S102. The dual fuel tank switching method for a vehicle in an exemplary embodiment is described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figure 1 As shown, in step S101, in response to a fuel tank switching instruction, the operating parameters of the vehicle are obtained.

[0030] In an example embodiment, the operating parameters include: one or more of: power mode, engine status, current fuel supply tank, and whether a target fuel supply tank system fails; the tank switching instruction is generated by the vehicle's display operation console based on the target fuel supply tank request information input by the user.

[0031] In a specific embodiment, the vehicle's display operation console receives target fuel supply tank request information input by a user to generate a tank switching instruction, the vehicle's EMS receives the tank switching instruction, and in response to the tank switching instruction, obtains the vehicle's power mode, engine status, current fuel supply tank, and whether the target fuel supply tank system has a fault.

[0032] It should be noted that the fuel tank switching command is input by the user to the display operation console through buttons or touch screen when the power mode of the vehicle is in the start gear.

[0033] Step S102: determining whether to switch the current fuel supply tank to the target fuel supply tank based on the operating condition parameters.

[0034] In an example embodiment, the vehicle has two fuel tanks, one of which is defined as the main fuel tank and the other as the auxiliary fuel tank. In one embodiment, if the current fuel supply tank is the main fuel tank, the target fuel supply tank may be the auxiliary fuel tank; in one embodiment, if the current fuel supply tank is the auxiliary fuel tank, the target fuel supply tank may be the main fuel tank; in other embodiments, if the current fuel supply tank is the main fuel tank or the auxiliary fuel tank, and the switch fails and needs to be switched back to the current fuel supply tank, the target fuel supply tank may also be the current fuel supply tank.

[0035] In a specific embodiment, in combination with the above embodiments, the vehicle's EMS receives a fuel tank switching instruction and, in response to the fuel tank switching instruction, obtains the vehicle's power mode, engine status, current fuel supply tank, and whether a target fuel supply tank system failure occurs, and determines whether to switch the current fuel supply tank to the target fuel supply tank.

[0036] according to Figure 1According to the technical solution in the example embodiment, in response to a fuel tank switching instruction, operating parameters of the vehicle are obtained, the operating parameters including: one or more of: power mode, engine status, current fuel supply tank, and whether a target fuel supply tank system fails; based on the operating parameters, it is determined whether to switch the current fuel supply tank to the target fuel supply tank; by obtaining the operating parameters of the vehicle, it is determined whether the vehicle meets the switching conditions, and the dual fuel tanks are switched when the switching conditions are met, which reduces the probability of switching failures caused by improper operation to a certain extent, thereby ensuring the normal driving of the vehicle to a certain extent.

[0037] In addition, through the technical solution in this embodiment, the vehicle's EMS controls the operation of the oil pump through the low-pressure oil pump control module integrated in the chip. After the engine is turned off, there will not be too much oil return, thereby avoiding the oil cross-talk phenomenon, and there is no need to add an oil return switching valve. When the main tank or auxiliary tank is supplying oil, the vehicle's EMS controls the oil pump to supply oil on demand according to the oil supply request of the vehicle's display operation console HUT, that is, the actual required injection amount of the engine is determined according to the engine speed and intake volume, and the size of the oil circuit opening is adjusted, which can effectively reduce the vehicle's fuel consumption and save energy and reduce emissions.

[0038] It should be noted that the above steps S101 to S102 are a brief introduction to the technical solution provided in the embodiment of the present application. The technical solution provided in the embodiment of the present application will be described in more detail below with reference to some examples.

[0039] In a specific embodiment, in step S101, in response to the fuel tank switching instruction, the vehicle operating parameters including the power mode, the engine state, the current fuel tank and the target fuel tank system are obtained without fault; then in step S102, according to the power mode, the engine state, the current fuel tank and the target fuel tank system, it is determined whether to switch the current fuel tank to the target fuel tank, that is, the current fuel tank is successfully switched to the target fuel tank, including the following situations:

[0040] In the first case: if the power mode is the start gear, the engine state is the stop state, the current fuel supply tank is the auxiliary fuel tank and the target fuel supply tank system has no faults, the auxiliary fuel tank is switched to the target fuel supply tank, wherein the target fuel supply tank is the main fuel tank.

[0041] In an example embodiment, in conjunction with Figure 2 As shown, if the current fuel supply tank is an auxiliary fuel tank, when the auxiliary fuel tank is switched to the main fuel tank, the vehicle's EMS determines that the power mode is the start gear ON gear; determines whether the current fuel supply tank is an auxiliary fuel tank and whether to switch manually; if so, determines whether the engine status is started, if it is in a stopped state, determines whether there is a fault in the target fuel supply tank system, and if there is no fault, switches the auxiliary fuel tank to the main tank.

[0042] It should be noted that the above-mentioned sequence of determining the operating parameters of the vehicle is only for illustration and does not impose any limitation on the present embodiment. The above-mentioned sequence of determining the operating parameters of the vehicle can be performed simultaneously or adjusted according to actual needs.

[0043] In the second case: if the power mode is in the start gear, the engine state is in the stop state, the current fuel supply tank is the main fuel tank and the target fuel supply tank system has no faults, the main fuel tank is switched to the target fuel supply tank, and the target fuel supply tank is the auxiliary fuel tank.

[0044] In an example embodiment, in conjunction with Figure 2 As shown, if the current fuel supply tank is the main tank, when the main tank is switched to the auxiliary tank, the vehicle's EMS determines that the power mode is the start gear ON gear; determines whether the current fuel supply tank is the main tank and whether to switch manually; if so, determines whether the engine state is started, if it is stopped, determines whether the target fuel supply tank system has a fault, if not, switches the main tank to the auxiliary tank. That is, the current fuel supply tank fails to switch to the target fuel supply tank, including the following situations:

[0045] The first case: if the power mode is the start gear, the engine state is the stop state, the current fuel supply tank is the auxiliary tank, and the target fuel supply tank system has a fault, the fault of the target fuel supply tank system is identified and a switching error is sent to the display operation console.

[0046] In the example embodiment, if the current fuel supply tank is an auxiliary fuel tank, when the auxiliary fuel tank is switched to the main fuel tank, the power mode is determined to be the start gear ON gear; it is determined whether the current fuel supply tank is an auxiliary fuel tank and whether it is switched manually; if so, it is determined whether the engine status is started, if it is in a stopped state, it is determined whether the target fuel supply tank system has any faults, and if the main tank fuel supply tank system has any faults, the fault of the main tank fuel supply tank system is identified, and the switching error is sent to the display operation console.

[0047] The second situation: if the power mode is the start gear, the engine state is the stop state, the current fuel supply tank is the main fuel tank and the target fuel supply tank system has a fault, then the fault of the target fuel supply tank system is identified and a switching error is sent to the display operation console.

[0048] In an exemplary embodiment, reference Figure 2As shown, if the current fuel supply tank is the main tank, when the main tank is switched to the auxiliary tank, the vehicle's EMS determines that the power mode is the start gear ON gear; determines whether the current fuel supply tank is the main tank, whether to switch manually; if so, determines whether the engine state is started, if it is stopped, determines whether the target fuel supply tank system has a fault, if the auxiliary tank fuel supply tank system has a fault, identifies the fault of the auxiliary tank fuel supply tank system, and sends a switching error to the display operation console. For example, send the text "failed to switch the auxiliary tank, please check and repair".

[0049] It should be noted that in the embodiment of the present application, when the vehicle is hit, the vehicle's EMS receives a collision signal, the main tank and the auxiliary tank both stop supplying fuel, the engine cylinders stop spraying fuel, the vehicle's EMS identifies the faults of the main tank supply tank system and the auxiliary tank supply tank system, and the switching fails. When identifying the fault of the target fuel supply tank system, for non-on-demand fuel supply models, the vehicle's EMS performs drive-level diagnosis on the fuel pump relays of the main tank and the auxiliary tank respectively; for on-demand fuel supply models, the vehicle's EMS diagnoses the fuel systems related to the main tank and the auxiliary tank respectively.

[0050] In addition, in this example embodiment, when the vehicle's EMS determines that the vehicle has entered the transport mode, in order to prevent the low-pressure oil pump from being damaged under the condition of too little oil, the vehicle's EMS determines whether it is necessary to enter the protection strategy of the main oil pump and the auxiliary oil pump according to the operating condition parameters. Under the protection strategy of the main oil pump and the auxiliary oil pump, switching failure may occur. When the vehicle's EMS determines that the vehicle is in the oil pump protection mode, the vehicle's EMS exits the main oil pump and the auxiliary oil pump protection strategy when the oil is sufficiently replenished or the transport mode is exited.

[0051] In combination with the above embodiments, in some other embodiments, after identifying the fault of the target fuel supply tank system and sending the switching error to the display operation console, it also includes: at an interval of a preset time period, in response to a tank switch back instruction, switching the target fuel supply tank back to the current fuel supply tank.

[0052] In an exemplary embodiment, reference Figure 2 As shown, in combination with the above embodiments, for example, when the current fuel supply tank is the auxiliary fuel tank and the auxiliary fuel tank is switched to the main fuel tank, the power mode is determined to be the start gear ON gear; it is determined whether the current fuel supply tank is the auxiliary fuel tank and whether it is switched manually; if so, it is determined whether the engine state is started, and if it is in the stopped state, it is determined whether the target fuel supply tank system has any faults, and if the main fuel tank fuel supply tank system has any faults, the fault of the main fuel tank fuel supply tank system is identified, and a switching error is sent to the display operation console, and after a preset time period, the vehicle's EMS receives the tank switch back instruction and switches back to the auxiliary fuel tank from the failed switching state.

[0053] In addition, in one embodiment, within the preset time interval, after the vehicle's EMS receives the fuel tank switching instruction first, and then receives the fuel tank switching back instruction, the vehicle's EMS sends a switching error to the display operation console, restarts the timing, and responds to the fuel tank switching back instruction again after the preset time interval, and switches the current fuel supply tank back to the auxiliary fuel tank. In other embodiments, if the fuel tank switching fails, it switches back to the auxiliary fuel tank after a preset time period. If the auxiliary fuel tank also fails, then the main fuel tank supply tank system and the auxiliary fuel tank supply tank system are both faulty, and the engine cannot be started because it cannot inject fuel.

[0054] It should be noted that in this example embodiment, the above example is taken as an example when the current fuel supply tank is the main fuel tank and the main fuel tank is switched to the auxiliary fuel tank. If the current fuel supply tank is the auxiliary fuel tank, the auxiliary fuel tank is switched to the main fuel tank, which is essentially the same as the above embodiment, and this example embodiment will not be repeated. In addition, the specific value of the preset time period involved in this example embodiment is not limited, and it shall be subject to the actual situation.

[0055] The third case: the above step S102 further specifically includes: if the power mode is the start gear, the engine state is the start state, and the current fuel supply tank is the main tank or the auxiliary tank, then sending an engine state non-compliance message to the display operation console so that the display operation console reminds the user to turn off the engine before switching.

[0056] In an exemplary embodiment, reference Figure 2 As shown, for example, when the current fuel supply tank is the main fuel tank and the main fuel tank is switched to the auxiliary fuel tank, the power mode is determined to be the start gear ON gear; it is determined whether the current fuel supply tank is the main fuel tank and whether it is switched manually; if so, it is determined whether the engine status is started, and if it is in the started state, a signal is sent to the display operation console that the engine status does not match, reminding the user to turn off the engine before switching; for example, the text is "Please turn off the engine before switching".

[0057] It should be noted that in this example embodiment, the above description is made by taking the current fuel supply tank as the main fuel tank and switching the main fuel tank to the auxiliary fuel tank as an example. If the current fuel supply tank is the auxiliary fuel tank and the auxiliary fuel tank is switched to the main fuel tank, the above embodiments are essentially the same and will not be repeated in this example embodiment.

[0058] The fourth situation: if the power mode is in the start gear, the engine state is in the stop state or the start state, the current fuel supply tank is the auxiliary fuel tank or the main fuel tank, and the target fuel supply tank system has a fault, the switching fails and continues to receive the tank switching command.

[0059] In an exemplary embodiment, reference Figure 2As shown, for example, when the current fuel supply tank is the main fuel tank and the main fuel tank is switched to the auxiliary fuel tank, the power mode is determined to be the start gear ON gear; it is determined whether the current fuel supply tank is the main fuel tank and whether it is switched manually; if so, it is determined whether the engine state is started, and if it is in the stopped state, it is determined whether there is a fault in the target fuel supply tank system. If there is a fault, the switch from the main fuel tank to the auxiliary fuel tank fails, and remains in the state of switching to the auxiliary fuel tank, and will not switch back to the main fuel tank. The fuel tank switching command is continuously received, and it is determined that the target fuel supply tank system fault is cleared before successfully switching to the auxiliary fuel tank.

[0060] It should be noted that in this example embodiment, the above description is made by taking the current fuel supply tank as the main fuel tank and switching the main fuel tank to the auxiliary fuel tank as an example. If the current fuel supply tank is the auxiliary fuel tank and the auxiliary fuel tank is switched to the main fuel tank, the above embodiments are essentially the same and will not be repeated in this example embodiment.

[0061] In other specific embodiments, in step S101, obtaining the operating parameters of the vehicle also includes whether the vehicle is powered on for the first time; then in step S102, determining whether to switch the current fuel supply tank to the target fuel supply tank is based on the power mode, engine status, the current fuel supply tank, whether the target fuel supply tank system has no faults, and whether the vehicle is powered on for the first time.

[0062] In an example embodiment, in conjunction with Figure 2 , determine whether the vehicle is powered on for the first time. If the vehicle is powered on for the first time, when the power mode is in the start gear, determine that the current fuel supply tank is the main fuel tank; if the vehicle is not powered on for the first time, determine whether to switch the current fuel supply tank to the target fuel supply tank based on the operating condition parameters. That is, if the vehicle is powered on for the first time, the EMS of the vehicle determines that the current fuel supply tank is the main fuel tank when the power mode of the vehicle is in the start gear. If the vehicle is not powered on for the first time, determine whether to switch the current fuel supply tank to the target fuel supply tank based on the operating condition parameters of the vehicle.

[0063] It should be noted that, in one embodiment, after the vehicle is powered on, the EMS of the vehicle does not receive the switching instruction sent by the display operation console HUT. At this time, the EMS switches the current fuel supply tank according to the switching instruction sent by the display operation console HUT after the last power-on. For example, when the vehicle is powered on for the second time, the EMS of the vehicle recognizes that the message sent by the display operation console HUT to switch the main fuel tank or the auxiliary fuel tank is lost. The EMS of the vehicle switches the current fuel supply tank according to the switching instruction sent by the display operation console HUT after the last power-on.

[0064] In another embodiment, after power-on, the vehicle's EMS receives a switching instruction sent by the display operation console HUT, and then the vehicle's EMS fails to receive the switching instruction. In this case, the current fuel tank is switched according to the switching instruction sent by the display operation console HUT before it goes offline. In addition, in other embodiments, a judgment may be made as to whether the vehicle is powered on for the first time after the vehicle leaves the production line, and no judgment is made thereafter. For example, after power-on, after the vehicle's EMS receives a switching instruction sent by the display operation console HUT, it recognizes that the switching message sent by the display operation console HUT is lost, and the vehicle's EMS processes the message according to the last frame sent by the display operation console HUT.

[0065] It should be noted that the vehicle drive types include fuel drive mode, hybrid drive mode and pure electric drive mode, and the technical methods in the above embodiments are applicable to fuel drive mode and hybrid drive mode. In pure electric drive mode, the vehicle's EMS controls the vehicle to enter transport mode, and strategically protects the main fuel tank or auxiliary fuel tank according to the working state of the engine to prevent damage to the low-pressure fuel pump under the condition of reduced fuel volume.

[0066] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application. For details not disclosed in the embodiment of the device of the present application, please refer to the embodiment of the method of the present application.
