[0024] In order to make the personnel in the technical field better understand the present application scheme, the technical scheme in the embodiment of the present application will be described clearly and completely in the following with reference to the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all. Based on the embodiment in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0025] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0026] According to an embodiment of the present application, an embodiment of a vehicle control method is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0027] Figure 1 is a flowchart of a vehicle control method according to an embodiment of the present application, as shown in Figure 1 The method comprises the following steps:

[0028] Step S102, obtaining a first cap state of a fuel cap in the vehicle, wherein the first cap state is used to represent whether the fuel cap is opened.

[0029] The fuel cap can be a cap installed on the upper part of the fuel tank of a fuel vehicle or a hybrid vehicle, which is used to seal the fuel tank and is one of the important safety devices in the vehicle refueling process. It is usually designed with a locking mechanism to prevent accidental opening during vehicle driving, so as to ensure the safety of the vehicle fuel system.

[0030] The first cap state can be whether the fuel cap is in an open state before the vehicle enters the preset control mode, and is used to preliminarily determine whether the vehicle is being refueled.

[0031] In an optional embodiment, considering that when the fuel cap is in an open state, the vehicle can be about to or is being refueled, the first cap state can be used as a basis for determining whether the vehicle will be refueled. By obtaining the first cap state of the fuel cap in the vehicle, the vehicle control system (hereinafter referred to as the control system) can automatically determine whether subsequent vehicle driving parameter or driving state acquisition is needed, and further determine whether safety measures need to be taken for the vehicle to ensure the safety of the vehicle during refueling.

[0032] For example, in order to improve the accuracy of obtaining the first cap state, one or more sensors can be installed in or around the fuel cap of the vehicle in advance. These sensors can be position sensors, proximity sensors, etc., which are used to detect the opening and closing state of the fuel cap. Specifically, the position sensor can be a microswitch-based device. When the fuel cap is opened, the state of the microswitch changes, so that the opening state of the cap can be detected. The proximity sensor can indirectly determine whether the cap is open by sensing whether there is a metal object (such as a refueling gun) near the fuel cap. When the sensor detects the opening and closing state of the fuel cap, a corresponding electrical signal is generated. This electrical signal can be transmitted to the control system through the electronic circuit of the vehicle, so that the control system can accurately obtain the first cap state in a timely manner.

[0033] Step S104: In a case where the first cap state indicates that the fuel cap is open, obtaining a first driving state of the vehicle.

[0034] The first driving state can be the driving state of the vehicle obtained when the first cap state indicates that the fuel cap is closed. The first driving state can include, but is not limited to, the vehicle speed, the gear position, and the state of charge of the power battery of the vehicle.

[0035] In an optional embodiment, considering that when the first cap state indicates that the fuel cap is open, the vehicle can need to be refueled, in order to more accurately determine whether the vehicle is about to or is being refueled, the control system can further obtain the first driving state of the vehicle, and can determine whether the vehicle is about to or is being refueled according to the state, and further determine whether safety measures need to be taken for the vehicle to avoid misjudgment and cause negative effects on the normal driving of the vehicle.

[0036] For example, when the first cap state is the oil cap closed, the control system can obtain the current vehicle speed information based on the pre-deployed wheel speed sensor, and can obtain the current gear information based on the transmission control unit, in addition, the control system can also obtain the state of charge of the power battery at the current time by using the battery management system, finally, the control system can construct the above-mentioned first driving state based on the vehicle speed information, gear information and state of charge.

[0037] Step S016, based on the first driving state, control the vehicle to enter a preset control mode, wherein the preset control mode is used to represent the mode of shielding the start request, and the start request is a request to start the engine in the vehicle.

[0038] The above-mentioned preset control mode can be a mode of automatically starting to shield any start request of the engine when it is identified that the vehicle is refueling, so as to ensure that the engine will not be started accidentally and avoid the risk of possible fuel vapor ignition.

[0039] The above-mentioned start request can be an instruction received by the control system, which requires to start or restart the vehicle.

[0040] In an optional embodiment, considering that if the first driving state also indicates that the vehicle is about to or is refueling, the control system can control the vehicle to shield the start request of the engine, so as to control the vehicle to enter the preset control mode, avoid engine ignition during refueling, and thus improve the safety of the vehicle during refueling.

[0041] For example, the control system can monitor the vehicle speed, gear, state of charge of the power battery and other information after the oil cap is opened, and once it is monitored that the vehicle speed is less than a preset value, or the gear is in N (neutral) or P (parking), or the state of charge meets the starting condition of the engine, the engine starting control loop can be immediately locked, and any start request from any source will be prevented, so that the vehicle enters the above-mentioned preset control mode.

[0042] In the embodiment of the present application, the first cap state of the oil cap in the vehicle is obtained, in the case that the first cap state represents that the oil cap is opened, the first driving state of the vehicle is obtained, and based on the first driving state, the vehicle is controlled to enter a preset control mode. By obtaining the first driving state after the oil cap is opened, it can be determined whether the vehicle is about to or is refueling in time and accurately, so that the vehicle can be controlled to enter the preset control mode when the vehicle is about to or is refueling, to avoid the engine starting during refueling, so as to achieve the purpose of intelligent and safe control of the vehicle during refueling, thereby realizing the technical effect of improving the control safety of the hybrid vehicle, and solving the technical problem of low control safety of the hybrid vehicle during refueling in the related art.

[0043] Further, based on the first driving state, the vehicle is controlled to enter a preset control mode, including: analyzing the first driving state to obtain a first analysis result, wherein the first analysis result is used to indicate whether the first driving state meets a first preset condition, and the first preset condition is used to indicate a condition for the vehicle to enter the preset control mode; and in a case where the first analysis result indicates that the first driving state meets the first preset condition, the vehicle is controlled to enter the preset control mode.

[0044] The first analysis result can be a conclusion obtained by the control system after monitoring and analyzing the current first driving state of the vehicle. Specifically, the first analysis result can be a binary judgment result, which is used to explicitly indicate whether the first driving state of the vehicle meets the first preset condition set by the system.

[0045] The first preset condition can be a series of rules or standards set to activate the preset control mode. Only when all related parameters of the first driving state meet the corresponding conditions in the first preset condition, the vehicle can enter the preset control mode.

[0046] In an optional embodiment, considering that when the first filler cap state is that the filler cap is open, it is still not enough to determine whether the vehicle is refueling, therefore, the control system needs to make further judgment on whether the vehicle is refueling based on the first driving state, to improve the accuracy of the control system for vehicle control. Therefore, the control system can make in-depth analysis of the first driving state to obtain the first analysis result, which is directly related to whether the first preset condition is met. The first preset condition specifically defines the necessary condition for the vehicle to enter the preset control mode. After the first analysis result confirms that the first driving state meets the first preset condition, the control system immediately executes the control strategy to guide the vehicle to smoothly transition to the preset control mode. This intelligent control process ensures the safe operation of the vehicle during refueling, and through accurate condition judgment and timely mode switching, efficient management and risk control of the vehicle operation are realized.

[0047] Specifically, the analysis of the first driving state can involve comprehensive consideration of multi-dimensional data such as vehicle speed, acceleration, position, and environmental parameters. The control system can form the first analysis result by real-time monitoring and intelligent analysis of these data, to effectively identify whether the vehicle is in a condition suitable for entering the preset control mode.

[0048] For example, in the scenario of refueling at a gas station, the control system can receive a first flap state from the vehicle body control unit that the flap is open. At this time, the control system can further monitor whether the vehicle speed is lower than a preset threshold, or the transmission gear is in N or P, or the state of charge of the power battery is higher than a preset state of charge, which together constitute the first driving state described above. The control system can analyze the first driving state to obtain a first analysis result. If the result indicates that the first driving state of the vehicle meets the first preset condition for entering the preset control mode, the control system can immediately control the vehicle to enter the preset control mode, execute the engine shutdown process, and lock the starting control loop to ensure that the engine does not start unexpectedly during refueling.

[0049] Further, the first driving state includes a first vehicle speed and a current gear of the vehicle, and a first state of charge of the power battery in the vehicle; and the first preset condition includes at least one of the following: the first vehicle speed is less than a first vehicle speed threshold; the current gear is a preset gear; and the first state of charge is greater than a first preset state of charge.

[0050] The first vehicle speed can be the driving speed of the vehicle at the current time before the vehicle enters the preset control mode.

[0051] The current gear can be the gear of the vehicle at the current time before the vehicle enters the preset control mode.

[0052] The first state of charge can be the ratio of the remaining capacity to the total capacity of the power battery of the vehicle at the current time before the vehicle enters the preset control mode.

[0053] The first vehicle speed threshold can be a preset speed value for determining whether the vehicle is in a stationary or near-stationary state. A speed lower than the first vehicle speed threshold can be considered as a stationary state, and a speed higher than the first vehicle speed threshold can be considered as a driving state.

[0054] The preset gear can be a gear that the vehicle needs to be in for safety or operational convenience during refueling, including but not limited to N gear and P gear.

[0055] The first preset state of charge can be a preset battery state of charge value for ensuring that the vehicle has sufficient power to avoid starting difficulties or limited functions.

[0056] In an optional embodiment, it is considered that by monitoring the first driving state of the vehicle, including the current speed of the vehicle, the gear position and the state of charge of the power battery, it can be determined whether the first driving state meets the first preset condition, thereby helping the control system to make a decision to determine whether to control the vehicle to enter the preset control mode. Specifically, the above-mentioned first preset condition can include: the vehicle speed is less than a first preset speed threshold, or the gear position is in a safe gear position N or P, or the state of charge of the power battery is greater than a first preset state of charge. When any of the above conditions is met, the control system will enable the safety measures in the refueling scenario, that is, control the vehicle to enter the preset control mode, to ensure the safety of the vehicle during refueling, and significantly reduce the safety risk caused by accidental start of the engine.

[0057] For example, in the scenario of refueling at a gas station, it can be assumed that the above-mentioned first speed threshold is 1 km / h. When the hybrid vehicle enters a stationary state, the vehicle speed is zero, which is less than 1 km / h, and the condition that the first speed is less than the first speed threshold is met. Therefore, the control system can immediately control the vehicle to enter the preset control mode.

[0058] For another example, the gear position of the vehicle is in P gear, which meets the condition that the current gear position is the preset gear position, and the first state of charge of the power battery is 60%, which is greater than the first preset state of charge of 40% that is preset, which meets the condition that the first state of charge is greater than the first preset state of charge. At this time, since the above-mentioned at least one preset condition is met, the control system automatically controls the vehicle to enter the preset control mode, thereby preventing the engine from accidentally starting during refueling.

[0059] It should be noted that the above-mentioned vehicle speed, first speed threshold, vehicle gear position, first state of charge and first preset state of charge are only exemplary, and the staff can set them according to actual needs, which are not limited here.

[0060] Further, after controlling the vehicle to enter the preset control mode, the method further comprises: monitoring the vehicle to obtain a second driving state of the vehicle; analyzing the second driving state to obtain a second analysis result, wherein the second analysis result is used to represent whether the second driving state meets a second preset condition, and the second preset condition is used to represent a condition for the vehicle to exit the preset control mode; and in the case that the second analysis result represents that the second driving state meets the second preset condition, controlling the vehicle to exit the preset control mode.

[0061] The above-mentioned second driving state can be the driving state of the vehicle obtained by the control system by monitoring the vehicle after the vehicle enters the preset control mode, which can include but is not limited to: the state of the fuel filler cap, the speed of the vehicle, the driving distance, and the state of charge of the power battery in the vehicle, etc.

[0062] The second analysis result can be a result obtained by analyzing the second driving state, and is compared with a second preset condition to determine whether the vehicle can safely exit the preset control mode.

[0063] The second preset condition can be a series of rules or standards set for the vehicle to safely exit the preset control mode, and only when all relevant parameters of the second driving state simultaneously satisfy the corresponding conditions in the second preset condition, the vehicle can exit the preset control mode.

[0064] In an optional embodiment, considering that the control system also needs to accurately determine when the vehicle can exit the preset control mode after the vehicle enters the preset control mode, the control system can further monitor the dynamic state of the vehicle after the vehicle enters the preset control mode, i.e., the engine is forcibly stopped and the start request is locked in the refueling scenario. Specifically, the control system can accurately obtain the second driving state information of the vehicle by continuously tracking key parameters such as the vehicle speed signal, the driving distance of the vehicle, the state of the fuel filler cap switch, and the state of charge of the power battery. Subsequently, the control system can analyze the second driving state and generate a second analysis result, which can indicate whether the vehicle has met the second preset condition, and further determine whether the vehicle has completed refueling. Once it is monitored that the second driving state meets the second preset condition, the control system can immediately release the engine stop lock state in the refueling scenario, i.e., control the vehicle to exit the preset control state, so as to restore the normal start-stop management logic of the vehicle, and ensure that the driver can seamlessly switch to the normal driving mode under the premise of safety. This dynamic monitoring and intelligent judgment exit mode not only enhances the overall safety of the vehicle in the refueling station environment, but also improves the driving experience, avoids unnecessary operation redundancy or waiting time, and realizes the dual improvement of safety and convenience.

[0065] For example, in the refueling scenario at the refueling station, after the vehicle enters the preset control mode, the control system can continuously monitor the vehicle state to obtain the second driving state of the vehicle, such as the vehicle speed, the gear change, and the state of charge of the power battery. If any one of the conditions that the vehicle speed exceeds a preset acceleration threshold, the fuel filler cap is closed, the driving distance of the vehicle exceeds a preset safety distance, or the state of charge of the power battery is lower than a warning threshold is met, the control system can control the vehicle to exit the preset control mode and restore the normal engine start-stop control logic.

[0066] Further, the second driving state comprises a second cap state of the fuel filler cap, a second vehicle speed and a driving distance of the vehicle, and a second state of charge of the power battery in the vehicle, the second cap state being used to represent whether the fuel filler cap is closed or not; the second preset condition comprises at least one of the following: the second cap state is that the fuel filler cap is closed; the second vehicle speed is greater than a second vehicle speed threshold, wherein the second vehicle speed threshold is greater than the first vehicle speed threshold; the driving distance is greater than a preset distance threshold; and the second state of charge is less than a second preset state of charge, wherein the second preset state of charge is less than the first preset state of charge.

[0067] The second cap state described above can be a state of whether the fuel filler cap is closed at the current time after the vehicle enters the preset control mode.

[0068] The second vehicle speed described above can be a driving speed of the vehicle at the current time after the vehicle enters the preset control mode.

[0069] The driving distance described above can be a moving distance of the vehicle from when the vehicle enters the preset control mode to the current time.

[0070] The second state of charge described above can be a ratio of a remaining amount of power to a total amount of power of the power battery of the vehicle at the current time after the vehicle enters the preset control mode.

[0071] The second vehicle speed threshold described above can be a preset vehicle speed value, which is higher than the first vehicle speed threshold, and is used to determine whether the vehicle has entered a normal driving state from a low-speed or stationary state.

[0072] The preset distance threshold described above can be a preset driving distance value, which is used to determine whether the vehicle has traveled far enough to be away from the flammable environment of the gas station.

[0073] The second preset state of charge described above can be a preset battery state of charge value, which is lower than the first preset state of charge, and is used to determine whether the state of charge of the power battery has been lowered to a degree that can affect the normal operation of the vehicle when the vehicle is refueling.

[0074] In an optional embodiment, considering that the second driving state of the vehicle is monitored, including the second cap state of the vehicle, the current vehicle speed, the driving distance, and the second state of charge of the power battery, it can be determined whether the second driving state meets the second preset condition, thereby helping the control system to make a decision to determine whether to control the vehicle to exit the preset control mode. Specifically, the above-mentioned second preset condition can include: the vehicle speed is greater than a preset second vehicle speed threshold, wherein the second vehicle speed threshold is greater than the first vehicle speed threshold, or the driving distance is greater than a preset distance threshold, or the state of charge of the power battery is less than a second preset state of charge, wherein the second preset state of charge is less than the first preset state of charge. When any of the above conditions is met, the control system will control the vehicle to exit the preset control mode to ensure that the vehicle can be switched to the normal driving mode in time to meet the power demand of the driver.

[0075] For example, after refueling at the gas station is completed, when the staff closes the fuel cap, the second cap state of the fuel cap becomes the fuel cap closed, which meets the second cap state of the second preset condition being the fuel cap closed. At this time, the control system can immediately control the vehicle to exit the preset control mode.

[0076] For another example, when the vehicle accelerates to be greater than the second vehicle speed threshold after leaving the gas station, which meets the second vehicle speed being greater than the second vehicle speed threshold in the second preset condition, at this time, the control system can immediately control the vehicle to exit the preset control mode.

[0077] For another example, even if the fuel cap of the vehicle is open, but the driving distance of the vehicle exceeds the preset distance threshold, which meets the driving distance being greater than the preset distance threshold in the second preset condition, at this time, the control system can still immediately control the vehicle to exit the preset control mode.

[0078] For another example, if the second state of charge of the power battery in the vehicle continues to decrease to be lower than the second preset state of charge, which meets the second state of charge being less than the second preset state of charge in the second preset condition, in order to avoid the second state of charge being too low to affect the normal start of the vehicle, the control system can control the vehicle to exit the preset control mode.

[0079] Further, after the vehicle enters the preset control mode, the method further comprises: monitoring the state of charge of the power battery of the vehicle to obtain a target state of charge; and outputting a target warning information in a case where the target state of charge is less than a third preset state of charge, wherein the third preset state of charge is greater than the second preset state of charge, and the third preset state of charge is less than the first preset state of charge, and the target warning information is used to prompt charging of the power battery.

[0080] The above-mentioned target state of charge can refer to the actual state of charge of the power battery of the vehicle at any time, i.e. the ratio of the remaining capacity to the total capacity of the battery.

[0081] The third preset state of charge can be a state of charge threshold of the vehicle power battery preset based on safety and functional requirements, smaller than the first preset state of charge and larger than the second preset state of charge. When the target state of charge is lower than the third preset threshold, the vehicle can trigger a response measure to prompt the driver that the state of charge of the power battery has dropped to a range that needs attention.

[0082] The target warning information can be a warning signal or prompt information to inform the driver that the target state of charge has dropped below the third preset state of charge, that is, the power of the power battery can be insufficient to support the normal operation of the basic functions of the vehicle or to ensure the response capability of the vehicle in an emergency.

[0083] In an optional embodiment, considering that if the state of charge of the power battery in the vehicle is too low, the normal functions of the vehicle will be affected, thereby affecting the driving safety of the vehicle, in order to timely remind the driver to charge the power battery before the state of charge of the power battery is too low, the control system can set a third preset state of charge, which can be smaller than the first preset state of charge and larger than the second preset state of charge. On the one hand, unnecessary prompt information can be avoided when the state of charge of the power battery is relatively sufficient, and on the other hand, a pre-warning function can be realized, that is, prompt information is output before the state of charge of the power battery is reduced to affect the normal starting of the vehicle. Based on this, the control system can monitor the state of charge of the power battery in the vehicle to obtain a target state of charge. When the target state of charge is monitored to be smaller than the third preset state of charge, the control system can immediately output target warning information to pre-warn the driver that the power of the power battery will reach a level insufficient to support the normal operation of the vehicle, so as to timely charge and avoid affecting the performance or safety of the vehicle due to insufficient power at an important moment.

[0084] For example, in the scenario of refueling at a gas station, when the target state of charge of the power battery of the vehicle is monitored to be 40%, which is smaller than the third preset state of charge 45%, the vehicle control system can output target warning information to prompt the driver to consider charging the power battery. In this case, the vehicle display screen will pop up a warning notice to inform the driver that the current battery power is low, and it is recommended to find a charging facility to supplement the power battery after refueling to ensure the stability and reliability of the power system in the subsequent journey.

[0085] It should be noted that the specific values of the target state of charge, the third preset state of charge, etc. are only exemplary and can be set by the staff according to actual needs, which are not limited herein.

[0086] Further, the output target alarm information includes: constructing the target alarm information based on the target state of charge; and outputting the target alarm information to the driver by using the graphical interactive interface.

[0087] The graphical interactive interface can be an interface capable of providing various information to the driver in the form of graphics, text or icons, and can include but not limited to a display screen in a vehicle information entertainment system, a head-up display device, etc.

[0088] In an optional embodiment, in order to intuitively let the driver know that the target state of charge of the vehicle is low, the control system can first construct the target alarm information based on the target state of charge, and can output the target alarm information to the driver in an intuitive way through the graphical interactive interface of the vehicle information entertainment system or the head-up display device, so as to remind the driver that the power battery is close to the lower limit and suggest taking appropriate measures, such as finding a charging facility. This alarm mechanism not only enhances the driver's perception of the vehicle state, but also pre-tips the possible functional limitation, so that the driver can make reasonable decisions in the refueling scenario, avoid subsequent problems caused by insufficient power battery, such as engine starting difficulty or vehicle function limitation, and thus ensure driving safety and user experience are not affected.

[0089] For ease of understanding, Figure 2 is a schematic diagram of an optional vehicle control method according to an embodiment of the present application, as shown in Figure 2 The interaction process involves ESC (Electronic Stability Control), BCM (Body Control Module), VCU (Vehicle Control Unit), BMS (Battery Management System) and IVI (In-Vehicle Infotainment), wherein a represents a vehicle speed signal sent by the ESC to the VCU, b represents a refueling door signal sent by the BCM to the VCU, c represents a low refueling power prompt signal sent by the VCU to the IVI, and d represents an actual SOC (State of Charge) sent by the BMS to the VCU.

[0090] Figure 3 is a schematic diagram of an optional dual-motor hybrid power system according to an embodiment of the present application, as shown in Figure 3As shown, the system includes an engine 301, a generator 302, a torque converter damper 303, a transmission gear 304, a disconnect clutch 305, a drive motor 306, and a main reducer 307. Among them, the engine 301 is connected with the torque converter damper 303, the torque converter damper 303 and the generator 302 are connected with the transmission gear 304, the transmission gear 304 is connected with the disconnect clutch 305, the disconnect clutch 305 is connected with the drive motor 306, and the drive motor 306 is connected with the main reducer 307. The above-mentioned components form a complete power transmission chain. In different operating modes, the control system can adjust the working state of the above-mentioned components according to the actual demand, so as to realize efficient energy utilization and driving mode switching. For example, when the vehicle is in pure electric driving mode, the engine 301 is stopped, and the disconnect clutch 305 is in a disconnected state. When the vehicle is in the starting mode, the drive motor 306 provides the driving force required for the vehicle to move forward to ensure that the vehicle does not stop, and the generator 302 works in the electric mode to drag the engine 301 to run to the oil injection ignition speed. When the engine 301 successfully injects oil and ignites, the generator 302 works in the power generation mode, and at this time, the engine 301, the generator 302 and the vehicle battery jointly provide power demand for the drive motor 306 to drive the vehicle. When the vehicle is in the stopping mode, after the generator 302 controls the engine 301 to reduce the speed to a preset threshold, the control system generates an instruction to stop the engine 301 from injecting oil, and the engine 301 runs by inertia until the engine 301 reduces to 0.
