[0002] With the gradual tightening of fuel consumption and emission regulations and the implementation of subsidy policies for new energy vehicles, the market share of hybrid vehicles has gradually increased. When charging conditions permit, users may not use the fuel in the vehicle tank for a long time, resulting in a significant drop in fuel utilization. Fuel will deteriorate if not used for a long time, which will have an adverse effect on engine performance. For example, fuel gelling will clog the injector, and the volatilization of fuel combustion components will cause the engine to work poorly, which will cause engine failure when the engine is used, resulting in user complaints. Therefore, how to prevent fuel deterioration is an urgent problem that needs to be solved. Summary of the invention

[0027] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0028] Reference below Figure 1-Figure 3 A method, device, vehicle and storage medium for preventing fuel deterioration according to an embodiment of the present invention are described.

[0029] Figure 1 FIG. 1 is a flow chart of a method for preventing fuel deterioration according to an embodiment of the present invention. Figure 1 A method for preventing fuel deterioration is shown, the method comprising the following steps:

[0030] Step S1: When the vehicle is powered on, the storage time of the fuel in the fuel tank of the vehicle is obtained.

[0031] Specifically, if the fuel in the vehicle's fuel tank is not used for a long time, it will deteriorate and affect the engine performance. Therefore, each time the vehicle is powered on, the storage time of the fuel in the tank is obtained so that when the fuel in the tank is stored for too long, the vehicle can be controlled to enter the fuel consumption mode and consume the fuel in the tank in time.

[0032] Step S2: Determine whether the placement time is greater than a first preset time.

[0033] Specifically, when the fuel storage time is greater than the first preset time, it is considered that the fuel storage time is too long and there is a risk of deterioration. It is necessary to control the vehicle to enter the fuel consumption mode to consume the fuel in the fuel tank in time. It is understandable that the first preset time can be determined according to the type of fuel. In a specific embodiment, the shelf life of E0 gasoline is generally 3-6 months, so the first preset time can be set to 2 months, and the shelf life of E10 ethanol gasoline is generally 1-3 months, so the first preset time can be set to half a month, so that when the fuel storage time exceeds the first preset time, the vehicle is controlled to enter the fuel consumption mode and the fuel in the fuel tank is consumed in time.

[0034] Step S3: When the idle time is greater than the first preset time and less than the second preset time, a first prompt message is issued, and when a control instruction to trigger the fuel consumption mode is received, the vehicle is controlled to enter the fuel consumption mode.

[0035] Specifically, in order to reduce user complaints and improve user experience, when the fuel storage time is greater than the first preset time and less than the second preset time, a first prompt message is issued to remind the user that the fuel in the tank has been stored for too long and there is a risk of deterioration. The user determines whether to control the vehicle to enter the fuel consumption mode. For example, the first prompt message is "The fuel of your car has been stored for too long and there is a risk of deterioration. Do you want to start the fuel consumption mode?" In a specific embodiment, the first prompt message can be displayed by the vehicle's instrument, that is, when the fuel storage time is greater than the first preset time and less than the second preset time, the vehicle's instrument is controlled to display the first prompt message to wait for the user's setting operation, that is, to solicit user opinions through the first prompt message, which can effectively reduce user complaints. When the user determines to start the fuel consumption mode through the instrument, that is, when the controller of the vehicle hybrid system receives a control instruction to trigger the fuel consumption mode, the vehicle is controlled to enter the fuel consumption mode to consume the fuel in the tank in time; when the user determines not to start the fuel consumption mode through the instrument, that is, when the controller of the vehicle hybrid system receives a control instruction not to trigger the fuel consumption mode, the instrument is controlled to exit the first prompt message, and the vehicle continues to travel in the original mode.

[0036] Step S4: When the standing time is greater than the second preset time, a second prompt message is issued, and the vehicle is controlled to enter a fuel consumption mode to consume the remaining fuel in the fuel tank.

[0037] Specifically, when the fuel storage time is greater than the second preset time, the controller of the vehicle hybrid system sends a second prompt message and controls the vehicle to enter the fuel consumption mode. It should be noted that the second prompt message is different from the first prompt message. The second prompt message is used to remind the user that the fuel in the vehicle tank has been stored for too long and there is a risk of deterioration, and the fuel consumption mode has been activated. That is, when the fuel storage time is greater than the second preset time, the controller of the vehicle hybrid system directly controls the vehicle to enter the fuel consumption mode without the user's setting. This is because when the fuel storage time is greater than the second preset time, it is considered that the fuel in the vehicle has a greater risk of deterioration and must be consumed as soon as possible to prevent the performance of the engine from being affected. That is, the second prompt message is used to remind the user that the vehicle has entered the fuel consumption mode, thereby avoiding the user from misjudging the vehicle's operating status. Exemplarily, the second prompt message is "The fuel of your car has been stored for too long, there is a risk of deterioration, and the fuel consumption mode has been activated." It can be understood that the second preset time can also be determined according to the type of fuel. In order to prevent fuel deterioration, the second preset time can be set before the fuel expiration date. For example, the shelf life of E0 gasoline is generally 3-6 months, so the second preset time can be set to 2 months or 3 months.

[0038] In one embodiment of the present invention, obtaining the storage time of fuel in the fuel tank of a vehicle includes: obtaining a first fuel storage time after the last fueling before the vehicle is powered on, the power-on time of the vehicle, and the time of the last fueling of the vehicle; calculating the difference between the power-on time and the time of the last fueling of the vehicle; and taking the sum of the difference and the first fuel storage time as the storage time of the fuel in the fuel tank of the vehicle.

[0039] Specifically, each time the vehicle is refueled, the controller of the vehicle hybrid system obtains a fuel placement time. After the last refueling before the vehicle is powered on, the controller of the vehicle hybrid system obtains the first fuel placement time. The sum of the time from the last refueling before the vehicle is powered on to the power-on of the vehicle and the first fuel placement time is the placement time of the fuel in the vehicle tank when the vehicle is powered on.

[0040] In one embodiment of the present invention, obtaining a first fuel standing time after the last fueling before the vehicle is powered on includes: obtaining a first fuel remaining amount before the last fueling before the vehicle is powered on and a second fuel remaining amount after the last fueling before the vehicle is powered on; and determining the first fuel standing time based on the first fuel remaining amount and the second fuel remaining amount.

[0041] Specifically, the remaining amount of fuel in the vehicle's fuel tank can be obtained through a fuel level sensor, and a first remaining amount of fuel is obtained before the last fueling before the vehicle is powered on, and a second remaining amount of fuel is obtained after the last fueling before the vehicle is powered on. The average fuel standing time after the last fueling before the vehicle is powered on can be determined based on the first remaining amount of fuel and the second remaining amount of fuel, and the average fuel standing time is used as the first fuel standing time, which has the advantage of accurate calculation.

[0042] In a specific embodiment, Figure 2 As shown, after the fuel level sensor obtains the first remaining fuel amount and the second remaining fuel amount, the first remaining fuel amount and the second remaining fuel amount are sent to the engine controller, and the engine controller determines the first fuel placement time based on the first remaining fuel amount and the second remaining fuel amount, and transmits the first fuel placement time to the controller of the vehicle hybrid system, and the controller of the vehicle hybrid system determines whether to trigger the fuel consumption mode to control the engine and control the instrument to output prompt information.

[0043] In one embodiment of the present invention, determining the first fuel standing time based on the first fuel remaining amount and the second fuel remaining amount includes: judging whether the ratio of the second fuel remaining amount to the first fuel remaining amount is greater than a preset ratio; if so, setting the first fuel standing time to zero; otherwise, determining the first fuel standing time based on the second fuel standing time before the vehicle was last refueled, the first fuel remaining amount, and the second fuel remaining amount.

[0044] Specifically, when the ratio of the second remaining fuel amount to the first remaining fuel amount is greater than a preset ratio, it is considered that the last fuel filling amount before the vehicle is powered on is large, and the influence of the remaining fuel in the fuel tank before the last fuel filling on the first fuel placement time can be ignored, that is, the first fuel placement time after the last fuel filling before the vehicle is powered on is zero. When the ratio of the second remaining fuel amount to the first remaining fuel amount is not greater than a preset ratio, it is considered that the remaining fuel in the fuel tank before the last fuel filling will affect the first fuel placement time. At this time, the first fuel placement time is determined based on the second fuel placement time before the last fuel filling of the vehicle, the first fuel remaining amount, and the second fuel remaining amount. It can be understood that the second fuel placement time before the last fuel filling of the vehicle can be determined based on the fuel remaining amount before the second to last fuel filling before the vehicle is powered on and the fuel remaining amount after the second to last fuel filling of the vehicle. The principle is the same as the above-mentioned determination of the first fuel placement time based on the first fuel remaining amount and the second fuel remaining amount, and will not be repeated here.

[0045] In a specific embodiment, the first remaining fuel amount is, for example, L 加油前 , the second remaining fuel quantity is, for example, L 加油后 , the preset ratio is, for example, K, the first fuel storage time is, for example, t1, and the second fuel storage time before the last fuel filling of the vehicle is, for example, t2. 加油后 / L 加油前 >K, t1=0.

[0046] In one embodiment of the present invention, determining the first fuel storage time according to the second fuel storage time before the last fuel filling of the vehicle, the first fuel remaining amount, and the second fuel remaining amount includes:

[0047] t = t1*L1 / L2;

[0048] Wherein, t is the first fuel storage time, t1 is the second fuel storage time before the vehicle is last refueled, L1 is the first fuel remaining amount, and L2 is the second fuel remaining amount.

[0049] In a specific embodiment, the second fuel placement time before the last fuel filling of the vehicle is, for example, t1, and the preset ratio is, for example, K. Then, when L1 / L2<=K, that is, when the ratio of the second remaining fuel amount to the first remaining fuel amount is not greater than the preset ratio, the first fuel placement time is t1*L1 / L2. It should be noted that the second fuel placement time before the last fuel filling of the vehicle can be determined based on the remaining fuel amount before the second-to-last fuel filling before the vehicle is powered on and the remaining fuel amount after the second-to-last fuel filling of the vehicle. The principle is the same as that of determining the first fuel placement time based on the first remaining fuel amount and the second remaining fuel amount as described above, and will not be elaborated here.

[0050] In one embodiment of the present invention, controlling a vehicle to enter a fuel consumption mode includes: adjusting a battery power maintenance range of the vehicle; and controlling an engine of the vehicle according to the battery power maintenance range to consume fuel in a fuel tank.

[0051] Specifically, the working modes of plug-in hybrid electric vehicles usually include charge depletion mode (i.e. CD mode: Charge Depleting) and charge retention mode (i.e. CS mode: Charge Sustaining). When the power battery has a high charge (generally higher than 20%), the vehicle works in charge depletion mode, and when the power battery has a low charge (generally lower than 20%), the vehicle works in charge retention mode. When the vehicle works in charge depletion mode, the vehicle's power system works in pure electric mode, that is, it is powered only by the power provided by the power battery, and when the vehicle works in charge retention mode, the power system uses hybrid power mode, that is, the engine and the power battery provide power together, and the battery charge is maintained within a predetermined range. When the fuel in the vehicle's fuel tank is left for too long, the controller of the vehicle's hybrid system controls the vehicle to enter the fuel consumption mode. In this mode, the controller of the vehicle's hybrid system adjusts the battery charge retention range of the vehicle and controls the vehicle's engine through the engine controller to consume the fuel in the tank in a timely manner, avoiding the risk of engine damage caused by the long-term storage of fuel in hybrid vehicles.

[0052] In one embodiment of the present invention, adjusting the battery power retention range of the vehicle includes: increasing the lower limit value of the battery power retention range to a first preset power, and increasing the upper limit value of the battery power retention range to a second preset power, wherein the second preset power is greater than the first preset power.

[0053] Specifically, since the lower limit of the battery power retention range is increased, when the battery power is higher than the original lower limit, the vehicle can be operated in the power retention mode, that is, the fuel in the fuel tank is consumed in time by the engine, thereby avoiding the risk of engine damage caused by long-term storage of fuel in hybrid vehicles. Furthermore, since the upper limit of the battery power retention range is increased, when the battery power is higher than the original upper limit, the vehicle can be operated in the power consumption mode, thereby further consuming the fuel in the fuel tank in time by the engine, thereby avoiding the risk of engine damage caused by long-term storage of fuel in hybrid vehicles.

[0054] In one embodiment of the present invention, the vehicle engine is controlled according to the battery power maintenance range, including: when the battery power is lower than a first preset power, issuing an engine start command to consume fuel in the fuel tank.

[0055] Specifically, when the battery power is lower than the first preset power, the controller of the vehicle hybrid system controls the engine to start and charge the battery until the battery power reaches the second preset power, so that the power is within the battery power maintenance range to consume the fuel in the tank. It should be noted that the embodiment of the present invention charges the battery only when the power is lower than the first preset power, rather than charging when the power is lower than the second preset power, in order to charge the battery when the power is lowered to a relatively lower level, thereby avoiding frequent start and stop of the engine.

[0056] According to the method for preventing fuel deterioration of an embodiment of the present invention, by obtaining the storage time of the fuel in the fuel tank of the vehicle when the vehicle is powered on, and setting the first preset time and the second preset time to control the vehicle to enter the fuel consumption mode, the fuel in the fuel tank can be consumed in time before the fuel deteriorates, effectively avoiding the risk of engine damage caused by the long-term storage of the fuel of the hybrid vehicle. Further, when the storage time of the fuel is greater than the first preset time and less than the second preset time, a first prompt message is issued to solicit user opinions through the first prompt message, which can effectively reduce user complaints and improve user experience; when the storage time of the fuel is greater than the second preset time, the controller of the vehicle hybrid system directly controls the vehicle to enter the fuel consumption mode without the need for user settings, and issues a second prompt message to remind the user that the vehicle has entered the fuel consumption mode through the second prompt message, thereby avoiding the user from misjudging the vehicle's operating status.

[0057] A further embodiment of the present invention also discloses a device for preventing fuel from deteriorating. Figure 3 FIG. 1 is a schematic diagram of a device for preventing fuel deterioration according to an embodiment of the present invention. Figure 3 As shown, the device 10 includes: an acquisition module 11, a judgment module 12, a first control module 13 and a second control module 14.

[0058] In one embodiment of the present invention, the acquisition module 11 acquires the storage time of the fuel in the vehicle's fuel tank, including: acquiring the first fuel storage time after the last fueling before the vehicle is powered on, the vehicle's power-on time and the time of the last fueling of the vehicle; calculating the difference between the power-on time and the time of the last fueling of the vehicle; and taking the sum of the difference and the first fuel storage time as the storage time of the fuel in the vehicle's fuel tank.

[0059] In one embodiment of the present invention, the acquisition module 11 acquires the first fuel storage time after the last fueling before the vehicle is powered on, including: acquiring the first fuel remaining amount before the last fueling before the vehicle is powered on and the second fuel remaining amount after the last fueling before the vehicle is powered on; determining the first fuel storage time according to the first fuel remaining amount and the second fuel remaining amount.

[0060] In one embodiment of the present invention, the device also includes a first determination module for determining the first fuel placement time based on the first fuel remaining amount and the second fuel remaining amount, including: judging whether the ratio of the second fuel remaining amount to the first fuel remaining amount is greater than a preset ratio; if so, setting the first fuel placement time to zero; otherwise, determining the first fuel placement time based on the second fuel placement time before the vehicle was last refueled, the first fuel remaining amount, and the second fuel remaining amount.

[0061] In one embodiment of the present invention, the first determination module determines the first fuel storage time according to the second fuel storage time before the last fuel filling of the vehicle, the first fuel remaining amount, and the second fuel remaining amount, including:

[0062] t = t1*L1 / L2;

[0063] Wherein, t1 is the second fuel storage time before the vehicle is last refueled, L1 is the first fuel remaining amount, and L2 is the second fuel remaining amount.

[0064] In one embodiment of the present invention, the first control module 13 or the second control module 14 controls the vehicle to enter a fuel consumption mode, including: adjusting the battery power maintenance range of the vehicle; controlling the vehicle's engine according to the battery power maintenance range to consume the fuel in the tank.

[0065] In one embodiment of the present invention, the first control module 13 or the second control module 14 adjusts the battery power retention range of the vehicle, including: increasing the lower limit value of the battery power retention range to a first preset power, and increasing the upper limit value of the battery power retention range to a second preset power, wherein the second preset power is greater than the first preset power.

[0066] In one embodiment of the present invention, the first control module 13 or the second control module 14 controls the vehicle's engine according to the battery power maintenance range, including: when the battery power is lower than a first preset power, issuing an engine start command to consume the fuel in the tank.

[0067] It should be noted that when the device 10 for preventing fuel deterioration in the embodiment of the present invention is used to prevent fuel deterioration, its specific implementation method is similar to the specific implementation method of the method for preventing fuel deterioration in the embodiment of the present invention.
