DETAILED DESCRIPTION

[0019] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0020] Figure 1 This is a flow chart of a method for preventing fuel expiration provided by this embodiment. This embodiment is applicable to the scenario of detecting and preventing fuel expiration in a hybrid electric vehicle. The method can be executed by an electronic device. The electronic device can be integrated in the vehicle computer or can be independent of the vehicle computer.

[0021] like Figure 1 As shown, this embodiment provides a method for preventing fuel from expiring, comprising the following steps: S110: If it is detected that the fuel in the vehicle is at risk of expiration, the operation mode of the vehicle is switched to a fuel priority mode.

[0022] The fuel in the vehicle refers to the fuel in the vehicle tank, and the risk of expiration refers to the time that the fuel stays in the tank close to the expiration date. Different types of fuel have different shelf lives, and the shelf life can be determined based on the type of fuel in the tank, and the fuel is determined to be at risk of expiration when it is close to the expiration date. Exemplarily, a third time period T3 is defined in advance based on the fuel type. If the current time is more than the third time period T3 from the last valid refueling time, it is considered that the fuel is at risk of expiration. Among them, the "last valid refueling time" is the time when a certain amount of fuel was last added to the tank, and the "last valid refueling time" can be determined in the following way.

[0023] When the fuel filler cap is detected to be open, the remaining fuel volume in the fuel tank before the fuel filler cap is opened is memorized as A liters. Then, fuel is added to the fuel tank. When the fuel filler cap is closed, the remaining fuel volume in the fuel tank is read as B liters. If the amount of fuel added exceeds the set ratio of the remaining fuel volume in the fuel tank, for example, 30%, that is, (BA) / A≥30%, then this refueling is judged to be effective, and the effective refueling time is memorized.

[0024] When it is detected that the current time is more than the third time T3 from the last effective refueling time, it is judged that the fuel in the tank is at risk of expiration. It should be noted that 30% is a calibration amount, which needs to be calibrated according to the actual vehicle status; T3 is also a calibration amount, which is generally considered to be 12 months according to relevant information.

[0025] The operating modes of hybrid vehicles include at least a fuel priority mode and a pure electric priority mode. In the fuel priority mode, when the battery power is low, the vehicle will give priority to using fuel for driving. The vehicle will be directly driven by the engine, and the battery will also be charged. This mode is suitable for long-term high-speed driving or when the battery power is too low. In the pure electric priority mode, when the power battery has a certain amount of power, the battery is used for driving first, and the engine is not started. In this embodiment, when there is a risk of expiration of the fuel, the operating mode of the vehicle is actively switched to the fuel priority mode. Of course, if the vehicle is currently in the fuel priority mode, there is no need to switch; if the vehicle is currently in the pure electric priority mode or other operating mode, it needs to automatically switch to the fuel priority mode.

[0026] Optionally, after switching to the fuel priority mode, the user is prompted: To avoid fuel expiration, automatically switch to the fuel priority mode.

[0027] S120: According to the remaining fuel amount, increase the first upper limit of the remaining battery power when starting the engine to obtain updated rules for the fuel priority mode.

[0028] The "increase" in this step means that compared with the normal situation, that is, when there is no risk of fuel expiration, the upper limit of the remaining battery power when starting the engine in the fuel priority mode is increased. Under normal circumstances, when the vehicle mode is fuel priority, the vehicle will start the engine when the remaining power of the power battery is ≤70%. In this embodiment, according to the remaining fuel in each segment, the first upper limit of the remaining power of the power battery corresponding to each segment of the remaining fuel is increased, for example, higher than 70%.

[0029] Exemplarily, multiple first intervals of remaining fuel are set; in each first interval, the first upper limit value of the remaining battery power when starting the engine is increased to obtain updated rules for the fuel priority mode; wherein, the more remaining fuel, the larger the first upper limit value, see the table below.

[0030] Table 1 Rules for fuel priority mode

[0031] Refer to Table 1. In the fuel priority mode, if the remaining fuel tank is ≥15L and the remaining power is ≤85%, the engine is started; if the remaining fuel tank is ≥10L and the remaining power is ≤80%, the engine is started; if the remaining fuel tank is ≥5L and the remaining power is ≤75%, the engine is started; if the remaining fuel tank is <5L and the remaining power is ≤70%, the engine is started.

[0032] The updated fuel priority mode rules are stored.

[0033] S130: If the current remaining fuel level and the current remaining power level of the vehicle meet the rules of the fuel priority mode, start the engine.

[0034] The current remaining fuel level of the vehicle and the current remaining power level of the power battery are compared in the updated rules of the fuel priority mode. If one of the rules (i.e., a column in Table 1) is matched, the updated rules of the fuel priority mode are met and the engine is started.

[0035] Optionally, if the vehicle's current remaining fuel level and current remaining battery power do not match any of the updated fuel priority mode rules, for example, the current remaining fuel level ≥ 15L, but the remaining battery power ≥ 90%, the battery can continue to be used as the power source.

[0036] It should be noted that the rules of the fuel priority mode will be updated only when the "fuel is at risk of expiration and is switched to fuel priority mode" provided in the present embodiment, that is, the remaining fuel amount is divided into segments and the first upper limit value is increased, so that when the battery has a high remaining power, the engine will still be started and fuel will be used as the power source to drive the vehicle.

[0037] Compared with the prior art, the beneficial effects of the embodiments of the present application are: This embodiment detects that there is a risk of expiration of the fuel in the vehicle, switches the operation mode of the vehicle to the fuel priority mode, and prepares to start the engine first; by adjusting the first upper limit of the remaining battery power when starting the engine according to the remaining fuel, and starting the engine when the current remaining fuel and the current remaining power of the vehicle meet the rules of the fuel priority mode, so that when the battery has a high remaining power, the engine will still be started, which is conducive to timely consumption of fuel and avoids the problem of vehicle damage and excessive exhaust gas caused by expired fuel. Moreover, this embodiment sets multiple first intervals of remaining fuel and first upper limit values ​​of remaining power for the rules of the fuel priority mode, and different first upper limit values ​​can be set according to different remaining fuel amounts, that is, different engine starting conditions can be set according to different remaining fuel amounts, and the consumption of battery power is taken into account while consuming fuel in a timely manner, which is conducive to improving the comprehensive endurance performance of the vehicle.

[0038] In some cases, after the vehicle's operating mode is switched to the fuel priority mode, if the user switches the operating mode back to the pure electric priority mode, for example, by selecting the pure electric priority mode on the vehicle's large screen, the rules of the pure electric priority mode need to be adjusted. Optionally, after the vehicle's operating mode is switched to the fuel priority mode, if the user switches the vehicle's operating mode to the pure electric priority mode, the second upper limit of the remaining battery power when starting the engine is adjusted up according to the remaining fuel, to obtain the updated rules of the pure electric priority mode. The "increase" in this step means that compared to the normal situation, that is, when there is no risk of expiration of the fuel, the upper limit of the remaining battery power when starting the engine in the pure electric priority mode is increased. Normally, when the vehicle mode is the pure electric priority mode, the vehicle will start the engine when the remaining power of the power battery is ≤20%. In this embodiment, the second upper limit of the remaining power of the power battery corresponding to each segment of the remaining fuel is increased, for example, higher than 20%.

[0039] Exemplarily, multiple second intervals of the remaining fuel amount are set; in each second interval, the second upper limit value of the remaining battery power when starting the engine is increased to obtain the updated rules of the pure electric priority mode; wherein, the more the remaining fuel amount, the larger the second upper limit value, see the table below.

[0040] Table 2 Rules for pure electric priority mode

[0041] Refer to Table 2. In pure electric priority mode, if the remaining fuel tank is ≥15L and the remaining power is ≤50%, start the engine; if the remaining fuel tank is ≥10L and the remaining power is ≤40%, start the engine; if the remaining fuel tank is ≥5L and the remaining power is ≤30%, start the engine; if the remaining fuel tank is <5L and the remaining power is ≤20%, start the engine. Store the updated rules of pure electric priority mode. Comparing Table 1 and Table 2, for the same first interval and second interval, the first upper limit value is greater than the second upper limit value. For example, when the remaining fuel amount is ≥10L, the first upper limit value is 80% and the second upper limit value is 40%.

[0042] If the vehicle's current remaining fuel and current remaining power meet the rules of the pure electric priority mode, the engine is started. The vehicle's current remaining fuel and the current remaining power of the power battery are compared in the updated rules of the fuel priority mode. If one of the rules (i.e., a column in Table 1) is matched, the updated rules of the fuel priority mode are met and the engine is started.

[0043] Optionally, if the vehicle's current remaining fuel level and current remaining battery power do not match any of the updated rules of the pure electric priority mode, for example, the current remaining fuel level ≥ 15L, but the remaining battery power ≥ 55%, the battery can continue to be used as the power source.

[0044] It should be noted that the rules of the pure electric priority mode will be updated only when "the fuel is at risk of expiration and is switched to fuel priority mode, and the user switches the vehicle's operating mode back to pure electric priority mode" provided in the present embodiment, that is, the remaining fuel amount is segmented and the second upper limit value is increased, so that when the battery has a high remaining power, the engine will still be started and fuel will be used as the power source to drive the vehicle.

[0045] This embodiment fully takes into account the user's desire to give priority to pure electric power. After the user switches back to the pure electric priority mode, multiple second intervals of remaining fuel and second upper limits of remaining power are set. Different second upper limits can be set according to different remaining fuel amounts, that is, different engine starting conditions are set according to different remaining fuel amounts. This consumes fuel in a timely manner while also taking into account battery power consumption, which is beneficial to improving the comprehensive endurance performance of the vehicle.

[0046] Figure 2 This is another method for preventing fuel expiration provided by the embodiment of the present application. Different methods are used to prevent fuel expiration based on the length of time the fuel has been in the tank (i.e., the time from the current time to the last effective refueling). Figure 2 , the method provided in this embodiment includes the following operations: S210: Obtain the last valid refueling time.

[0047] S220, determining whether the current time is longer than the last effective refueling time by a third duration T3, if yes, executing S221, if no, executing S230.

[0048] S221. Switch the operation mode of the vehicle to a fuel priority mode; and continue to execute S222.

[0049] Optionally, if the current time is more than a third time period T3 from the last effective refueling time, the current operating mode is recorded, so that after the vehicle is refueled, the operating mode of the vehicle is switched to the operating mode of the historical record to improve the user experience.

[0050] S222: Determine whether the user switches the operation mode back to the pure electric priority mode. If yes, execute S223; otherwise, execute S224.

[0051] S223. According to the remaining fuel amount, increase the second upper limit value of the remaining battery power when starting the engine to obtain the updated rules of the pure electric priority mode; if the current remaining fuel amount and the current remaining battery power of the vehicle meet the rules of the pure electric priority mode, start the engine.

[0052] S224. According to the remaining fuel amount, increase the first upper limit value of the remaining battery power when starting the engine to obtain the updated rules of the fuel priority mode; if the current remaining fuel amount and the current remaining battery power of the vehicle meet the rules of the fuel priority mode, start the engine.

[0053] S230, determining whether the current time is greater than the second time duration T2 from the last effective refueling time, if so, executing S231, if not, executing S240.

[0054] S231. Switch the vehicle's operating mode to a fuel priority mode.

[0055] The second time period T2 is obtained through calibration and may be 6 months. If the current time from the last effective refueling time exceeds the second time period T2, the current operating mode is recorded, so that after the vehicle is refueled, the operating mode of the vehicle is switched to the operating mode of the historical record, thereby improving the user experience.

[0056] In this embodiment, if the current time is longer than the second time length T2 from the last effective refueling time, it is also necessary to actively switch the vehicle's operating mode to the fuel priority mode; at the same time, a set reminder message is sent to the user to inform the user: In order to avoid damage to the engine caused by expired fuel, the vehicle mode will be actively switched to the fuel priority mode.

[0057] After the vehicle mode is actively switched to the fuel priority mode, if the user does not want to use the fuel priority mode, the user can select other vehicle modes through the vehicle mode interface of the vehicle computer, but the selection of other modes is only valid for a single driving cycle. For example, if the user switches the vehicle's operating mode to the pure electric priority mode, the pure electric priority mode will be maintained during this power-on cycle. The vehicle will still actively switch to the fuel priority mode after the next power-on.

[0058] Optionally, if the current time is longer than the second time duration T2 from the last valid refueling time, when switching to the fuel priority mode, the rules of the fuel priority mode can be maintained under normal circumstances; when the user switches back to the pure electric priority mode, the rules of the pure electric priority mode can be maintained under normal circumstances.

[0059] S240, determine whether the current time is longer than the first time duration T1 from the last effective refueling time, if yes, execute S241, if not, return to S210.

[0060] T1 is the calibration amount, which is usually considered to be 3 months based on relevant information. If the first time period T1 is exceeded, it is considered that the fuel has a relatively small risk of expiration, and the current remaining fuel volume is further obtained.

[0061] S241. Obtain the current remaining fuel level of the vehicle; if the current remaining fuel level exceeds the fuel level reference value, send a set reminder message to the user.

[0062] For example, if the current remaining fuel level does not exceed the fuel level reference value, such as 5L, it is considered that there is less fuel or even no fuel in the fuel tank, and it is considered that the user may refuel recently or will not use fuel, so no reminder is given to the user. On the contrary, if the current remaining fuel level exceeds the fuel level reference value, it is considered that there is still a lot of fuel in the fuel tank, and a set reminder message needs to be sent to the user.

[0063] For "sending a setting reminder message to the user", this embodiment adopts different sending methods according to different states of the vehicle. First, determine the current state of the vehicle, and determine whether the vehicle is in a running state or a parking state through the vehicle speed sensor and the gear state. If the current state is in a running state, a setting reminder message is sent to the user through the vehicle computer. The electronic device is connected to the vehicle computer through a cloud network, and a setting reminder message is sent to the vehicle computer based on the communication link. The vehicle computer informs the user through voice or visual means that the fuel is about to expire, and please use fuel first to drive and switch to the fuel priority mode. If the current state is in a parking state, a setting reminder message is sent to the user's portable terminal. Specifically, the electronic device is connected to the user's portable terminal (such as a mobile phone, a smart watch or a tablet computer, etc.) through a cloud wireless network, and a setting reminder message is sent to the portable terminal based on the communication link, for example: vehicle mode recommendation: fuel priority; fuel expiration impact: it will cause certain damage to the engine, spark plugs, fuel injectors and other components. The content of the "setting reminder message" provided in this embodiment is only an example, and those skilled in the art or users can set the content of the "setting reminder message" in the electronic device in advance.

[0064] In this embodiment, when "sending a set reminder message to the user", in order to avoid frequent reminders to the user, which brings unnecessary troubles to the user. In this embodiment, when the current time is more than the fourth time length T4 from the last effective refueling time, a set reminder message is sent to the user. Among them, T4 can be calibrated, for example, 2.5 months. If the user still does not refuel after this, a set reminder message is sent to the user when the current time is more than the first time length T1 from the last effective refueling time. If the vehicle is not refueled within the set time period (for example, 10 days), a set reminder message is sent to the user according to the set frequency (for example, once a month). When the current time is more than the second time length T2 from the last effective refueling time, the vehicle's operating mode is actively switched to the fuel priority mode, but the rules of the fuel priority mode under normal circumstances can be maintained. When the current time is more than the third time length T3 from the last effective refueling time, the vehicle's operating mode is actively switched to the fuel priority mode; at the same time, the rules of the fuel priority mode and the pure electric priority mode are updated, and the engine is started when the corresponding rules are met.

[0065] The embodiments of the present application take into account that the most direct impact of expired fuel on a car is insufficient engine power, and then the engine runs roughly, which will cause blockage, carbon deposition and other problems over time, affecting vehicle power. The method provided by the present application can avoid the above problems caused by expired fuel to the engine as much as possible.
