Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle control method, a control device, a vehicle and a readable storage medium. Background Art

[0002] At present, cars have become an important means of transportation. However, if a car is not started for a long time, the battery will continue to discharge during the static process, resulting in battery depletion. Battery depletion will cause the entire car to fall into an undervoltage state, and the entire car may not even be awakened when it is depleted. With the development and rapid popularization of automobiles, the number of cars in use is increasing, resulting in an increasing number of vehicles with depletion problems, which greatly reduces the user experience of using the vehicle.

[0003] After a power failure occurs, the common method for reviving the vehicle is to jump-start the vehicle. After the jump-start is successful, the charging device can be started to put the vehicle into normal working condition. However, users often think that after the charging device is started, the vehicle can operate normally and the jump-start is ended. In fact, due to the different charging devices, the time required for the output power to meet the normal working state of the vehicle is different. If the jump-start is ended during the charging period, the vehicle may fall into an undervoltage state again, and the abnormal shutdown of the charging device will cause certain damage. Summary of the invention

[0004] The present application provides a vehicle control method, a control device, a vehicle and a readable storage medium, which are used to predict the charging time of a charging device to charge a battery after determining that the vehicle is awakened by a jump start, and display the countdown of the charging time, so as to avoid the problem that the vehicle falls into an undervoltage state again due to artificial interruption of the jump start. The technical solution of the present application is as follows:

[0005] According to a first aspect of the present application, a vehicle control method is provided, comprising: after determining that the vehicle is awakened by a jump-start, obtaining the stock of an energy medium in a charging device; if the stock of the energy medium is greater than or equal to a preset stock, starting the charging device to charge the battery, the preset stock is related to the operating power of the vehicle; predicting the charging time of the charging device; and displaying a countdown of the charging time.

[0006] According to the above technical means, the present application can determine whether the vehicle's energy medium inventory is greater than or equal to the preset inventory after determining that the vehicle is awakened by jumping power, that is, after the vehicle recovers from an undervoltage state, that is, whether the vehicle's energy medium inventory can maintain the vehicle running at normal power for a period of time. If the vehicle's energy medium inventory can maintain the vehicle running at normal power for a period of time, the charging time of the charging device to charge the battery is predicted, and the countdown of the charging time is displayed. That is to remind the user that the vehicle still needs some time to charge and cannot leave the vehicle immediately, which can avoid the problem of the vehicle falling into an undervoltage state again due to artificial interruption of jumping power. At the same time, it can avoid damage caused by abnormal shutdown of the charging device after the vehicle falls into an undervoltage state.

[0007] In a possible implementation, before starting the charging device to charge the battery, the method also includes: judging whether to start the power device based on the stock of the energy medium; if the power device is not started, the charging time is the time from when the power battery starts charging to when the output power of the DC converter device reaches a first preset power.

[0009] In a possible implementation, when the power device is started, the charging time of the charging device is predicted, specifically: the charging time from the start of the power device to the output power of the power device reaching the second preset power is predicted.

[0010] According to the above technical means, the present application can accurately predict the charging time of the power device to charge the battery according to the state of the vehicle and the parameters of the power device when it is necessary to start the power device.

[0012] According to the above-mentioned technical means, the present application can prompt the user to replenish the energy medium when the energy medium stock of the vehicle is less than the preset stock, that is, when the energy medium stock of the vehicle cannot maintain the vehicle running at normal power for a period of time, and at the same time give the location of the charging facility near the vehicle, so that the user can replenish the energy medium at the charging facility, which can improve the user's experience.

[0013] In a possible implementation, before obtaining the energy medium stock of the charging device, the control method also includes: obtaining a first voltage value and a second voltage value; the first voltage value is the voltage value of the battery before the vehicle enters an undervoltage state, and the second voltage value is the voltage value of the battery after the vehicle is awakened; when the difference between the second voltage value and the first voltage value is greater than a preset voltage difference, if the DC converter device is in a non-working state, it is determined that the vehicle is awakened by a jump power supply.

[0014] According to the above technical means, the present application can judge whether the vehicle is awakened by a jump battery according to the voltage value of the battery, and can more accurately judge the vehicle's awakening method, providing a reliable basis for the control process of the vehicle after awakening.

[0015] In a possible implementation, after displaying the countdown of the charging time, the control method further includes: after the countdown of the charging time ends, if the DC converter device is in a working state and the output current of the DC converter device is greater than a preset current value, outputting a second prompt message, and the second prompt message is used to prompt the user that the vehicle can start driving.

[0016] According to the above technical means, the present application can further judge the state of the vehicle after the countdown of the predicted charging time ends. If the DC-DC device is in working state and the output current of the DC-DC device is greater than the preset current value, indicating that the vehicle can be started normally, a second prompt message is output to prompt the user to drive the vehicle normally. This further prevents the user from starting the vehicle too early, causing the vehicle to fall into an undervoltage state again.

[0017] According to the second aspect provided by the present application, a vehicle control device is provided, including: an acquisition module, used to obtain the stock of an energy medium in a charging device after determining that the vehicle is awakened by a jump-start; a start module, used to start the charging device to charge the battery when the stock of the energy medium is greater than or equal to a preset stock, and the preset stock is related to the operating power of the vehicle; a prediction module, used to predict the charging time of the charging device; and a display module, used to display the countdown of the charging time.

[0018] In a possible implementation, the vehicle control device further includes: a judgment module, configured to judge whether to start the power device according to the amount of the energy medium. If the power device is not started, the charging time is the time from when the power battery starts charging to when the output power of the DC converter device reaches the first preset power.

[0019] In a possible implementation, when the power device is started, the prediction module is specifically configured to predict the charging time from when the power device is started to when the output power of the power device reaches a second preset power according to the state of the vehicle and the parameters of the power device.

[0020] In a possible embodiment, the acquisition module is also used to obtain the location of a charging facility within a preset distance from the vehicle based on the location information of the vehicle when the stock of the energy medium is less than the preset stock; the vehicle control device also includes: an output module, used to output a first prompt information, the first prompt information includes the location of the charging facility, and is used to prompt the user to replenish the energy medium at the charging facility.

[0021] In a possible implementation, the acquisition module is further used to acquire a first voltage value and a second voltage value; the first voltage value is the voltage value of the battery before the vehicle enters the undervoltage state, and the second voltage value is the voltage value of the battery after the vehicle wakes up. The vehicle control device also includes: a determination module, which is used to determine that the vehicle is woken up by a jump start when the difference between the second voltage value and the first voltage value is greater than a preset voltage difference and the DC converter device is in a non-working state.

[0022] In a possible implementation, the output module is also used to output a second prompt message after the countdown of the charging time ends, if the DC converter device is in a working state and the output current of the DC converter device is greater than a preset current value, and the second prompt message is used to prompt the user that the vehicle can start driving.

[0023] According to the third aspect provided by the present application, a vehicle is provided, comprising: a processor; a memory for storing processor executable instructions; wherein the processor is configured to execute instructions to implement the method of the above-mentioned first aspect and any possible implementation manner thereof.

[0024] According to the fourth aspect provided by the present application, a computer-readable storage medium is provided. When the instructions in the computer-readable storage medium are executed by the processor of the vehicle, the vehicle is enabled to execute the method in the above-mentioned first aspect and any possible implementation method thereof.

[0025] According to the fifth aspect provided by the present application, a computer program product is provided, the computer program product comprising computer instructions, and when the computer instructions are executed on a vehicle, the vehicle executes the method of the above-mentioned first aspect and any possible implementation manner thereof.

[0026] Therefore, the above technical features of the present application have the following beneficial effects:

[0027] (1) After determining that the vehicle is awakened by jumping power, that is, after the vehicle recovers from an undervoltage state, it can be determined whether the vehicle's energy medium inventory is greater than or equal to the preset inventory, that is, whether the vehicle's energy medium inventory can maintain the vehicle's operation at normal power for a period of time. If the vehicle's energy medium inventory can maintain the vehicle's operation at normal power for a period of time, the charging time of the charging device to charge the battery is predicted, and the countdown of the charging time is displayed. In other words, it reminds the user that the vehicle still needs some time to charge and cannot leave the vehicle immediately, which can avoid the problem of the vehicle falling into an undervoltage state again due to human interruption of jumping power. At the same time, it can avoid damage caused by abnormal shutdown of the charging device after the vehicle falls into an undervoltage state.

[0028] (2) Whether to start the power device can be determined based on the amount of energy medium stored. Without starting the power device, the charging time of the power battery to charge the storage battery can be accurately predicted.

[0029] (3) When the power device needs to be started, the charging time of the power device to charge the battery can be accurately predicted based on the vehicle status and the parameters of the power device.

[0030] (4) When the energy medium reserve of the vehicle is less than the preset reserve, that is, when the energy medium reserve of the vehicle cannot maintain the vehicle running at normal power for a period of time, the user can be prompted to replenish the energy medium and the location of the charging facility near the vehicle can be given at the same time, so that the user can replenish the energy medium at the charging facility, thereby improving the user's experience.

[0031] (5) It is possible to determine whether the vehicle is awakened by a jump start based on the battery voltage value. This can more accurately determine the vehicle's wake-up method, providing a reliable basis for the vehicle's control process after wake-up.

[0032] (6) After the countdown of the predicted charging time ends, the vehicle status can be further determined. If the DC-DC device is in working condition and the output current of the DC-DC device is greater than the preset current value, indicating that the vehicle can be started normally, a second prompt message is output to prompt the user to drive the vehicle normally. This further prevents the user from starting the vehicle too early, causing the vehicle to fall into an undervoltage state again.

[0033] It should be noted that the technical effects brought about by any implementation method in the second to fifth aspects can refer to the technical effects brought about by the corresponding implementation method in the first aspect, and will not be repeated here.

[0034] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and control methods consistent with some aspects of the present application as detailed in the attached claims.

[0045] As described in the background technology, jump-charging after a vehicle runs out of power is a commonly used technical means. For example, the related technology discloses a system and method for recharging a car battery. This method solves the problem that when solving the problem of battery power failure by external jump-charging, it is necessary to lead out the battery jumper wire, jump-charging has many requirements and is inconvenient to operate. However, it also ignores the problem that the vehicle falls into undervoltage again due to some human or non-human reasons. However, this problem cannot be ignored in the jump-charging process, and after the jump-charging interruption causes the vehicle to fall into undervoltage again, users often think that it is caused by other problems of the vehicle, so they can only wait for rescue on the spot and wait for the tow truck to transport it to a professional maintenance agency for inspection, which is time-consuming, labor-intensive and resource-intensive, and greatly reduces user satisfaction with the car.

[0046] Based on this, the vehicle control method provided by the present application determines whether the energy medium stock of the vehicle is greater than or equal to the preset stock after the vehicle is awakened by jump-starting, that is, after the vehicle recovers from an undervoltage state, that is, whether the energy medium stock of the vehicle can maintain the vehicle running at normal power for a period of time. If the energy medium stock of the vehicle can maintain the vehicle running at normal power for a period of time, the charging time of the charging device to charge the battery is predicted, and the countdown of the charging time is displayed. That is to remind the user that the vehicle still needs some time to charge and cannot leave the vehicle immediately, which can avoid the problem of the vehicle falling into an undervoltage state again due to artificial interruption of jump-starting. At the same time, it can avoid damage caused by abnormal shutdown of the charging device after the vehicle falls into an undervoltage state.

[0047] For ease of understanding, the vehicle control method provided in the present application is described in detail below with reference to the accompanying drawings.

[0048] Figure 1 is a flow chart of a vehicle control method according to an exemplary embodiment. Figure 1 As shown, the vehicle control method includes the following steps:

[0049] S101. After determining that the vehicle is awakened by a jump battery, obtain the energy medium stock of the charging device.

[0050] Since the vehicle control system wakes up after being powered on, the low-voltage controller of the vehicle can work normally, the system re-reads vehicle data, user information, etc., and the vehicle charging system uploads real-time data of the charging device to the vehicle control system, including but not limited to the fuel tank oil level, power battery power, fuel cell energy and other energy medium stocks.

[0051] S102: If the energy medium stock is greater than or equal to the preset stock, start the charging device to charge the battery.

[0052] The preset stock is related to the operating power of the vehicle. As a feasible implementation method, the preset stock S bat≥P NR T NR , P NR is the power required for normal vehicle operation, T NR The preset time is the preset amount of energy required to meet the normal operation of the vehicle for the preset time.

[0053] If the energy medium stock is greater than or equal to the preset stock, it indicates that the vehicle's energy medium stock can meet the normal operation of the vehicle for a period of time. The vehicle control system sends a start command to the charging device, allowing the charging device to charge the battery.

[0054] As a feasible implementation method, when starting the charging device to charge the battery, turn off other loads of the vehicle except for charging and emergency alarm related functions to reduce the load as much as possible to shorten the charging time.

[0055] S103: predicting the charging time of the charging device.

[0056] In some embodiments, since the energy medium stock includes but is not limited to the oil level in the fuel tank, the power level of the power battery, the energy level of the fuel cell, etc., the energy medium stock is different, and the charging method of the charging device to the battery is also different, so before charging the battery, it is necessary to determine the charging method.

[0057] As a feasible implementation method, before starting the charging device to charge the battery, it is necessary to determine whether to start the power device based on the stock of the energy medium.

[0058] It should be understood that the power device includes but is not limited to an electric motor and an engine. In a pure electric vehicle, the power device is an electric motor; in a hybrid vehicle, the power device is an electric motor and an engine; in a fuel vehicle, the power device is an engine.

[0059] For example, if the power battery in the energy medium inventory is greater than the preset inventory, it indicates that there is no need to start the power device, and only the power battery can be used for charging. If the power battery is insufficient, the power device needs to be started to drive the generator to run and convert the energy in other devices into electrical energy.

[0060] As a feasible implementation method, without charging the power device, the power battery system can be directly started to charge the whole vehicle. At this time, the charging time is the time T from the start of the power battery system to the output power of the direct current-direct current (DC-DC) device that can meet the normal operation power consumption of the whole vehicle. BatNR .

[0061] As another feasible implementation method, if the power unit needs to be started for charging, the vehicle control system and the power unit controller need to calculate the time T from the start of the power unit to the power unit generating the power required for the normal operation of the vehicle according to the current vehicle state and power unit parameters. E_NR , T E_NR As charging time.

[0062] S104: Display the countdown of charging time.

[0063] After the charging time is obtained, the countdown is displayed on the vehicle screen to remind the user. After the charging device is started, the countdown to the end of the jump-start mode is displayed on the vehicle, and the user is prompted to count down by voice. It should be understood that the control logic and reminder countdown time are different depending on the vehicle model, and the embodiment of the present application does not make any limitation on this.

[0064] It should be understood that the jump-starting mode described in the embodiment of the present application is to obtain the energy medium stock of the charging device; and perform corresponding operations according to the relationship between the energy medium stock and the preset stock.

[0065] Users usually think that the jump-start can be completed after the vehicle is successfully started, but in fact, the power device has not yet issued a stable power that meets the power consumption of the entire vehicle. The output power of the power device is less than the power consumption of the normal operation of the entire vehicle. If the user ends the jump-start and drives away from the vehicle, it is easy to cause the vehicle to fall into an undervoltage state again. The control method provided in the embodiment of the present application can predict the charging time of the vehicle and display it, preventing the user from starting the vehicle before charging is completed, causing the vehicle to fall into an undervoltage state again.

[0066] In some embodiments, after a vehicle has been stored for a long time, the amount of energy medium in the vehicle's charging device may be small and cannot meet the preset time for normal operation of the vehicle. That is, the vehicle may run out of energy medium after charging for a period of time. Figure 2 As shown, the vehicle control method provided in the embodiment of the present application, after obtaining the energy medium stock of the charging device, further includes the following steps:

[0067] S201. If the energy medium stock is less than a preset stock, obtain the location of a charging facility within a preset distance from the vehicle based on the location information of the vehicle.

[0068] If the energy medium storage of the charging device is less than the preset storage, it indicates that the energy medium storage of the vehicle cannot meet the normal operation of the vehicle for a period of time, and the vehicle may run out of energy medium after charging for a period of time. In this case, the amount of energy medium to be replenished is determined, that is, the amount of energy medium that the user needs to replenish.

[0069] S202: Output first prompt information.

[0070] The first prompt information includes the location of the charging facility, which is used to prompt the user to replenish the energy medium at the charging facility.

[0071] If the energy medium stock is less than the preset stock, it cannot meet the system setting of the normal operation time T of the vehicle control system after the power-on is completed. NR If the energy of the vehicle is insufficient, the vehicle screen will remind the user that the energy medium needs to be replenished, and the location of the charging facility near the vehicle will be given. This will allow the user to replenish the amount of energy medium at the charging facility, which can improve the user experience.

[0072] As a feasible implementation method, when the energy medium stock is less than the preset stock, the amount of energy medium that needs to be replenished can be determined based on the energy medium stock and the preset stock, and the amount of replenished energy medium can be output to facilitate users to replenish the energy medium.

[0073] In some embodiments, since there are many ways to wake up the vehicle, before obtaining the energy medium inventory of the charging device, it is necessary to determine whether the vehicle wakes up after being powered on. Figure 3 As shown, the vehicle control method provided in the embodiment of the present application further includes the following steps before obtaining the energy medium stock of the charging device:

[0074] S301. Obtain a first voltage value and a second voltage value.

[0075] The first voltage value is the voltage value of the battery before the vehicle enters the undervoltage state, and the second voltage value is the voltage value of the battery after the vehicle wakes up.

[0076] S302: When the difference between the second voltage value and the first voltage value is greater than a preset voltage difference, if the DC-DC device is in a non-operating state, it is determined that the vehicle is powered on and awakened.

[0077] Get the first battery voltage value Udown a few seconds before the vehicle falls into the undervoltage shutdown state, the second battery current voltage value Uup after the control system wakes up, and the working state of the DC-DC device. If the difference between Uup and Udown is greater than or equal to the preset voltage difference Uwarn set by the system to trigger this mode, and the DC-DC device is in a non-working state, the system determines that the vehicle is awakened by a jump start and automatically enters the jump start mode.

[0078] According to the above technical means, the present application can judge whether the vehicle is awakened by a jump-start according to the voltage value of the battery and the working state of the DC-DC device. It can more accurately judge the vehicle's awakening method and provide a reliable basis for the control process of the vehicle after awakening.

[0079] In some embodiments, since the charging time is predicted by the system, in actual application, the predicted charging time may not be accurate. In order to avoid the problem of inaccurate system prediction, the control system provided in the embodiment of the present application, after displaying the countdown of the charging time, the control method also includes: after the countdown of the charging time ends, if the DC-DC device is in a working state and the output current of the DC-DC device is greater than the preset current value, a second prompt message is output.

[0080] The second prompt information is used to prompt the user that the vehicle can start driving.

[0081] After the countdown of the charging time ends, the system collects the vehicle's power on and off status, the DC-DC device's working status, the DC-DC output current IDC-DC_OUT, and the charging system's operating status. If the DC-DC device is in working status and the DC-DC output current IDC-DC_OUT meets the normal operating power consumption of the vehicle, the user is reminded to end the jump-start and restore the vehicle.

[0082] According to the above technical means, the present application can further judge the state of the vehicle after the countdown of the predicted charging time ends. If the DC-DC device is in working state and the output current of the DC-DC device is greater than the preset current value, indicating that the vehicle can be started normally, a second prompt message is output to prompt the user to drive the vehicle normally. This further prevents the user from starting the vehicle too early, causing the vehicle to fall into an undervoltage state again.

[0083] In some embodiments, in order to reduce the load and shorten the charging time, other loads of the vehicle except for charging and emergency alarm related functions need to be turned off during charging. As a feasible implementation method, after the second prompt message is output, the functions turned off to reduce the load are restored, the charging mode is automatically exited, and the vehicle resumes normal use.

[0084] In some embodiments, see Figure 4 After the vehicle is awakened, the vehicle control method provided by the embodiment of the present application includes the following steps:

[0085] S401、U up -U down ≥U warn , and C DC-DC In non-working state.

[0086] That is, determine whether the difference between the first battery voltage value Udown a few seconds before the vehicle falls into the undervoltage shutdown state and the second battery current voltage value Uup after the control system wakes up is greater than or equal to U warn , and the working state of the DC-DC device is C DC - DCIs it in a non-working state? If yes, execute S4011; if no, execute S4021.

[0087] S4011. The vehicle automatically enters the jump-start mode and shuts down vehicle loads except for charging-related and emergency alarm functions.

[0088] S4012, the vehicle status data and vehicle energy status data are transmitted to the vehicle control module.

[0089] Determine the energy medium inventory of the charging device.

[0090] S4013. Determine whether energy medium needs to be supplemented.

[0091] If not, execute S4014; if so, execute S4022.

[0092] S4014, the vehicle control module calculates the normal operation time T of the vehicle system NR Required power S NR , and calculate the electric energy S generated by the charging device after operation NR Time required.

[0093] S4015. Start the charging system to charge, and display the countdown to the end of charging on the vehicle screen and give a voice prompt to the user.

[0094] S4016. After the countdown ends, the vehicle control module collects the operating parameters of the charging system, and reminds the user to end the charging process when the power consumption balance is met for normal system operation, and restores the functions that were previously turned off to reduce power consumption.

[0095] S4021, do not enter the jump-start mode.

[0096] If U up -U down Less than U warn , or C DC -DC is in working state, which means the vehicle is not awakened by jump-starting. The vehicle does not need to enter jump-starting mode and can be used normally.

[0097] S4022, the vehicle control module calculates the normal operation time of the vehicle system T NR , the car screen displays the amount of energy medium that needs to be replenished.

[0098] When the energy medium needs to be replenished, the amount required is calculated. At the same time, the car screen can also display the location of nearby charging facilities to facilitate charging for users.

[0099] For example, usually after jump-starting, the user needs to press the key to wake up the vehicle. However, the control method provided in this application does not require user operation. It is completely controlled by the vehicle control system to determine whether to enter the jump-start mode and when to exit the jump-start mode after entering. Figure 5 The jump-start mode requires the vehicle status monitoring module 51, the energy management module 52, the vehicle control module 50, the charging system 53, and the smart cockpit module 54 to work together in coordination. The vehicle control module 50 collects the voltage value after recovery and the voltage value before entering the power-deficient shutdown state through the vehicle status monitoring module 51 and the energy management module 52, and compares them with the working state of the DC-DC device to determine whether the vehicle is revived by jump-starting.
