Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a vehicle control method, control device, vehicle, and readable storage medium. Background Technology

[0002] Currently, automobiles have become an important means of transportation. However, if a car is not started for an extended period, the battery will continue to discharge, leading to a depleted battery. A depleted battery can cause the entire vehicle to fall into an undervoltage state, and in some cases, the car may even be unable to be started. With the development and rapid popularization of automobiles, the number of cars on the road is constantly increasing, resulting in a growing number of vehicles experiencing battery depletion issues, significantly diminishing the user experience.

[0003] When a vehicle experiences a power outage, the common method for recovery is jump-starting. Once the jump-start is successful, the charging device can be activated to bring the vehicle back to normal operation. However, users often assume that once the charging device is activated, the vehicle can run normally and thus end the jump-starting process. In reality, due to differences in charging devices, the time required for their output to meet the vehicle's normal operating power requirements varies. If the jump-start is terminated during charging, the vehicle may fall back into a low-voltage state, and an abnormal shutdown of the charging device can cause damage. Summary of the Invention

[0004] This application provides a vehicle control method, control device, vehicle, and readable storage medium. After determining that the vehicle has been jump-started, the method predicts the charging time for the charging device to charge the battery and displays a countdown timer, thus preventing the vehicle from falling back into an undervoltage state due to manual interruption of the jump-start. The technical solution of this application is as follows:

[0005] According to a first aspect of this application, a vehicle control method is provided, comprising: after determining that the vehicle is jump-started, obtaining the amount of energy medium stored in a charging device; if the amount of energy medium is greater than or equal to a preset amount, activating the charging device to charge the battery, wherein the preset amount is related to the vehicle's operating power; predicting the charging time of the charging device; and displaying a countdown of the charging time.

[0006] Based on the aforementioned technical means, this application can determine whether the vehicle's energy medium reserve is greater than or equal to a preset reserve after the vehicle has been jump-started, i.e., after the vehicle has recovered from an undervoltage state. In other words, it can determine whether the vehicle's energy medium reserve can sustain the vehicle's normal power operation for a period of time. If the vehicle's energy medium reserve can sustain the vehicle's normal power operation for a period of time, the charging time for the charging device to charge the battery is predicted, and a countdown timer is displayed. This serves as a reminder to the user that the vehicle still needs some time to charge and should not be driven away immediately, thus avoiding the problem of the vehicle falling back into an undervoltage state due to manual interruption of the jump-start. It also prevents damage caused by abnormal shutdown of the charging device after the vehicle has fallen into an undervoltage state.

[0007] In one possible implementation, before activating the charging device to charge the battery, the method further includes: determining whether to activate the power device based on the amount of energy medium; if the power device is not activated, the charging time is the time from the start of charging of the power battery to the time from the output power of the DC-DC converter device reaching a first preset power.

[0008] Based on the aforementioned technical means, this application can determine whether to start the power device based on the amount of energy medium available, and accurately predict the charging time of the power battery to charge the storage battery when the power device does not need to be started.

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

[0010] Based on the aforementioned technical means, this application can accurately predict the charging time of the power unit to charge the battery when the power unit needs to be started, according to the vehicle's status and the parameters of the power unit.

[0011] In one possible implementation, after obtaining the energy medium storage of the charging device, the method further includes: if the energy medium storage is less than a preset storage, obtaining the location of the charging facility within a preset distance from the vehicle based on the vehicle's location information; and outputting a first prompt message, the first prompt message including the location of the charging facility, to prompt the user to replenish the energy medium at the charging facility.

[0012] Based on the aforementioned technical means, this application can prompt the user to replenish the energy medium when the vehicle's energy medium inventory is less than the preset inventory, that is, when the vehicle's energy medium inventory cannot sustain the vehicle to operate at normal power for a period of time. At the same time, it can provide the location of charging facilities near the vehicle so that the user can replenish the energy medium at the charging facilities, thereby improving the user experience.

[0013] In one possible implementation, before acquiring the energy medium storage of the charging device, the control method further includes: acquiring 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 woken up; if the difference between the second voltage value and the first voltage value is greater than a preset voltage difference, and the DC-DC converter device is in a non-operating state, then it is determined that the vehicle is being woken up by jump-start.

[0014] Based on the aforementioned technical means, this application can determine whether a vehicle is being woken up by jump-starting based on the battery voltage. This allows for a relatively accurate determination of the vehicle's wake-up method, providing a reliable basis for the vehicle's control procedures after wake-up.

[0015] In one 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-DC converter is in operation and the output current of the DC-DC converter is greater than a preset current value, outputting a second prompt message, the second prompt message being used to prompt the user that the vehicle can be driven.

[0016] Based on the aforementioned technical means, this application can further determine the vehicle's status after the countdown of the predicted charging time has ended. If the DC-DC device is in working condition and its output current is greater than the preset current value, indicating that the vehicle can start normally, a second prompt message is output to remind the user to drive the vehicle normally. This further prevents the user from starting the vehicle too early, causing the vehicle to fall back into an undervoltage state.

[0017] According to a second aspect provided in this application, a vehicle control device is provided, comprising: an acquisition module for acquiring the amount of energy medium stored in a charging device after determining that the vehicle is being jump-started; a start module for starting the charging device to charge the battery when the amount of energy medium is greater than or equal to a preset amount, wherein the preset amount is related to the vehicle's operating power; a prediction module for predicting the charging time of the charging device; and a display module for displaying a countdown of the charging time.

[0018] In one possible implementation, the vehicle control device further includes a determination module for determining whether to start the power unit based on the available energy medium. If the power unit is not started, the charging time is the time from the start of charging of the power battery to the time when the output power of the DC-DC converter reaches a first preset power.

[0019] In one possible implementation, when the power unit is started, the prediction module is specifically configured to predict the charging time from the start of the power unit to the output power of the power unit reaching a second preset power, based on the vehicle's state and the parameters of the power unit.

[0020] In one possible implementation, the acquisition module is further configured to, when the energy medium is less than a preset amount, acquire the location of a charging facility within a preset distance from the vehicle based on the vehicle's location information; the vehicle control device further includes: an output module, configured to output first prompt information, the first prompt information including the location of the charging facility, to prompt the user to replenish the energy medium at the charging facility.

[0021] In one possible implementation, the acquisition module is further configured to acquire a first voltage value and a second voltage value; the first voltage value is the battery voltage value before the vehicle enters an undervoltage state, and the second voltage value is the battery voltage value after the vehicle is woken up. The vehicle control device further includes a determination module, configured to determine that the vehicle is being jump-started when the difference between the second voltage value and the first voltage value is greater than a preset voltage difference and the DC-DC converter is in a non-operating state.

[0022] In one possible implementation, the output module is further configured to, after the countdown of the charging time has ended, if the DC-DC converter is in operation and the output current of the DC-DC converter is greater than a preset current value, output a second prompt message, the second prompt message being used to prompt the user that the vehicle can be driven.

[0023] According to a third aspect provided in this 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 first aspect described above and any possible implementation thereof.

[0024] According to a fourth aspect provided in this application, a computer-readable storage medium is provided that, when the instructions in the computer-readable storage medium are executed by a processor of a vehicle, enables the vehicle to perform the methods described in the first aspect and any possible implementation thereof.

[0025] According to the fifth aspect provided in this application, a computer program product is provided, the computer program product including computer instructions that, when executed on a vehicle, cause the vehicle to perform the method described in the first aspect and any possible implementation thereof.

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

[0027] (1) After confirming that the vehicle has been jump-started, i.e., after the vehicle has recovered from an undervoltage state, it can determine whether the vehicle's energy medium reserve is greater than or equal to the preset reserve, i.e., whether the vehicle's energy medium reserve can sustain the vehicle's normal power operation for a period of time. If the vehicle's energy medium reserve can sustain the vehicle's normal power operation 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. This reminds the user that the vehicle still needs a period of time to charge and should not be driven away immediately, which can avoid the problem of the vehicle falling back into an undervoltage state due to human interruption of jump-start. At the same time, it can avoid the damage caused by the abnormal shutdown of the charging device after the vehicle falls into an undervoltage state.

[0028] (2) It can determine whether to start the power device based on the amount of energy medium. If the power device does not need to be started, it can accurately predict the charging time of the power battery to charge the storage battery.

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

[0030] (4) When the energy medium of the vehicle is less than the preset amount, that is, when the energy medium of the vehicle cannot maintain the vehicle running at normal power for a period of time, the user is prompted to replenish the energy medium. At the same time, the location of the charging facility near the vehicle is given so that the user can replenish the energy medium at the charging facility, which can improve the user experience.

[0031] (5) The vehicle can be woken up by jump-starting based on the battery voltage. This can accurately determine the vehicle's wake-up method and provide a reliable basis for the vehicle's control process after wake-up.

[0032] (6) The vehicle's status can be further assessed after the countdown of the predicted charging time has ended. If the DC-DC device is in operation and its output current is greater than the preset current value, it indicates that the vehicle can start normally, and a second prompt message is output to remind 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 of any of the implementation methods in aspects two through five can be found in the technical effects of the corresponding implementation methods in aspect one, and will not be repeated here.

[0043] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0044] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and control methods consistent with some aspects of this application as detailed in the appended claims.

[0045] As described in the background section, jump-starting a vehicle after it has run out of power is a common technical method. For example, related technologies disclose a system and method for replenishing a car battery. This method solves the problem of needing to run jumper cables when externally jumping to solve a battery drain issue, which has many requirements and is inconvenient to operate. However, it also overlooks the problem of jump-start interruptions due to human or non-human factors, causing the vehicle to fall back into a low-voltage state. This problem is unavoidable during jump-starting, and when a jump-start interruption causes the vehicle to fall back into a low-voltage state, users often assume it's due to other vehicle problems, leaving them with no choice but to wait for roadside assistance and a tow truck to transport the vehicle to a professional maintenance facility for inspection. This is time-consuming, labor-intensive, and resource-intensive, significantly reducing user satisfaction.

[0046] Based on this, the vehicle control method provided in this application, after the vehicle is jump-started and woken up (i.e., after the vehicle recovers from an undervoltage state), determines whether the vehicle's energy medium reserve is greater than or equal to a preset reserve, that is, whether the vehicle's energy medium reserve can sustain the vehicle's normal power operation for a period of time. If the vehicle's energy medium reserve can sustain the vehicle's normal power operation for a period of time, the charging time of the charging device to charge the battery is predicted, and a countdown of the charging time is displayed. This reminds the user that the vehicle still needs a period of charging and should not be driven away immediately, thus avoiding the problem of the vehicle falling back into an undervoltage state due to manual interruption of jump-starting. At the same time, it can prevent damage caused by abnormal shutdown of the charging device after the vehicle has fallen into an undervoltage state.

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

[0048] Figure 1 This is a flowchart illustrating a vehicle control method according to an exemplary embodiment, such as... Figure 1 As shown, the vehicle control method includes the following steps:

[0049] S101. After determining that the vehicle is being jump-started, obtain the energy medium storage of the charging device.

[0050] After the vehicle control system is powered on, the low-voltage controllers of the vehicle can work normally. The system rereads 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 amount of fuel in the tank, the power battery charge, the energy of the fuel cell, and other energy media.

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

[0052] The pre-set inventory is related to the vehicle's operating power. As a feasible implementation method, the pre-set inventory S... bat≥P NR T NR P NR T represents the power required for the vehicle to operate normally. NR This is a preset time. In other words, the preset energy level is the energy required to ensure the vehicle operates normally for the preset time.

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

[0054] As a feasible approach, when the charging device is activated to charge the battery, all other loads on the vehicle except for charging and emergency alarm-related functions are turned off, so as to reduce the load as much as possible and shorten the charging time.

[0055] S103, Predict the charging time of the charging device.

[0056] In some embodiments, the energy medium includes, but is not limited to, fuel tank level, battery charge, and fuel cell energy. Since different energy medium quantities require different charging methods, it is necessary to determine the charging method before charging the battery.

[0057] As a feasible approach, before activating the charging device to charge the battery, it is necessary to determine whether to activate the power unit based on the available energy medium.

[0058] It should be understood that the power unit includes, but is not limited to, electric motors and engines. In pure electric vehicles, the power unit is an electric motor; in hybrid electric vehicles, the power unit is both an electric motor and an engine; and in gasoline-powered vehicles, the power unit is an engine.

[0059] For example, if the power battery's charge in the energy storage is greater than the preset amount, it means that there is no need to start the power unit; the power battery alone can provide energy. If the power battery's charge is insufficient, the power unit needs to be started to drive the generator, converting energy from other devices into electrical energy.

[0060] As a feasible approach, without requiring a power unit to charge the vehicle, the power battery system can be directly started to charge the entire vehicle. In this case, the charging time is the time T from the start of the power battery system, as assessed by the system, to the output power of the direct current-to-direct current (DC-DC) converter being sufficient to meet the normal operating power consumption of the vehicle. BatNR .

[0061] As another feasible approach, if the power unit needs to be started for charging, the vehicle control system and the power unit controller need to calculate, based on the current vehicle status and power unit parameters, the time T from when the power unit starts until it delivers the power required for the vehicle to operate normally. E_NR , will T E_NR As charging time.

[0062] S104, Displaying a countdown timer for charging time.

[0063] After the charging time is obtained, a countdown timer is displayed on the vehicle's infotainment screen to remind the user. Once the charging device is activated, a jump-start completion reminder countdown begins, displaying the jump-start mode countdown timer on the vehicle's infotainment system and providing voice prompts to the user to indicate the countdown. It should be understood that the control logic and reminder countdown timer may differ depending on the vehicle model, and this application embodiment does not impose any limitations on them.

[0064] It should be understood that the jump-start mode described in the embodiments of this application is to obtain the energy medium storage of the charging device and perform corresponding operations according to the relationship between the energy medium storage and the preset storage.

[0065] Users typically believe that jump-starting is complete once the vehicle starts successfully. However, in reality, the power unit has not yet delivered a stable power output sufficient for the vehicle's overall power consumption. The power unit's output power is less than the vehicle's normal operating power consumption. If the user ends the jump-start and drives away from the vehicle at this time, it can easily cause the vehicle to fall back into an undervoltage state. The control method provided in this application can predict and display the vehicle's charging time, preventing the user from starting the vehicle before charging is complete, thus preventing the vehicle from falling back into an undervoltage state.

[0066] In some embodiments, after a vehicle has been stored for an extended period, the amount of energy medium stored in the vehicle's charging device may be insufficient to meet the vehicle's preset normal operating time. In other words, the vehicle may run out of energy medium after charging for a certain period. Figure 2 As shown, the vehicle control method provided in this application embodiment, after obtaining the energy medium storage of the charging device, further includes the following steps:

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

[0068] If the energy medium in the charging device is less than the preset amount, it indicates that the vehicle's energy medium supply is insufficient to meet the vehicle's normal operating needs for a period of time. The vehicle may run out of energy medium after charging for a certain period. In this case, the amount of energy medium to be replenished is determined, i.e., the amount of energy medium the user needs to replenish.

[0069] S202, Output the first prompt message.

[0070] The first notification includes the location of the charging facility, which prompts the user to replenish the energy medium at the charging facility.

[0071] If the energy medium inventory is less than the preset inventory, that is, if it cannot meet the system's set normal operating time T of the vehicle control system after the power jump-start is terminated. NR If the vehicle's energy level is low, the infotainment system will display a notification on the screen indicating the need to replenish the energy medium, along with the location of nearby charging stations. This allows users to easily replenish the energy medium at designated charging points, enhancing the user experience.

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

[0073] In some embodiments, since there are multiple ways to wake up a vehicle, it is necessary to determine whether the vehicle is woken up via jump-start before obtaining the energy medium storage of the charging device. For example... Figure 3 As shown, the vehicle control method provided in this application embodiment further includes the following steps before obtaining the energy medium storage of the charging device:

[0074] S301, Obtain the first voltage value and the second voltage value.

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

[0076] S302. If the difference between the second voltage value and the first voltage value is greater than the preset voltage difference, and the DC-DC device is not in operation, then the vehicle is determined to be in a jump-start state.

[0077] The system acquires the battery's first voltage value (Udown) a few seconds before the vehicle enters an undervoltage shutdown state, the battery's current voltage value (Uup) after the control system is woken up, and the operating status of the DC-DC device. If the difference between Uup and Udown is greater than or equal to the preset voltage difference value (Uwarn) set by the system to trigger this mode, and the DC-DC device is not in operation, the system determines that the vehicle is being jump-started and automatically enters jump-start mode.

[0078] Based on the aforementioned technical means, this application can determine whether a vehicle is being woken up by jump-starting based on the battery voltage and the operating status of the DC-DC device. This allows for a relatively accurate determination of the vehicle's wake-up method, providing a reliable basis for the vehicle's control procedures after wake-up.

[0079] In some embodiments, since the charging time is predicted by the system, the predicted charging time may not be accurate in actual application. In order to avoid the problem of inaccurate system prediction, the control system provided in this application embodiment further includes the following control method after displaying the countdown of the charging time: after the countdown of the 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, outputting a second prompt message.

[0080] The second notification message is used to inform the user that the vehicle is ready to be driven.

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

[0082] Based on the aforementioned technical means, this application can further determine the vehicle's status after the countdown of the predicted charging time has ended. If the DC-DC device is in working condition and its output current is greater than the preset current value, indicating that the vehicle can start normally, a second prompt message is output to remind the user to drive the vehicle normally. This further prevents the user from starting the vehicle too early, causing the vehicle to fall back into an undervoltage state.

[0083] In some embodiments, to reduce the load and shorten the charging time, it is necessary to turn off all vehicle loads except for charging and emergency alarm-related functions during charging. As a feasible implementation, after outputting the second prompt message, the functions that were turned off to reduce the load are restored, the jump-start mode is automatically exited, and the vehicle returns to normal use.

[0084] In some embodiments, please refer to Figure 4 After the vehicle is activated, the vehicle control method provided in this application includes the following steps:

[0085] S401, U up -U down ≥U warn And C DC-DC In non-working status.

[0086] Specifically, it determines whether the difference between the battery's first voltage value Udown a few seconds before the vehicle enters an undervoltage shutdown state and the battery's current voltage value Uup after the control system is activated is greater than or equal to U. warn And the operating state C of the DC-DC device DC - DCIs the system in a non-working state? If yes, execute S4011; otherwise, execute S4021.

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

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

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

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

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

[0092] S4014, The vehicle control module calculates the required normal operating time T for the entire vehicle system. NR Required electrical energy S NR And calculate the electrical energy S generated after the charging device is running. NR Time required.

[0093] S4015: Start the charging system to charge the battery, and display a countdown timer for the end of the jump start on the vehicle's infotainment screen, along with a voice prompt to the user.

[0094] S4016. After the countdown ends, the vehicle control module collects the operating parameters of the charging system. If the power consumption balance is met during normal system operation, the user is reminded to end the jump-start and the functions that were previously turned off due to reduced power consumption are restored.

[0095] S4021, Do not enter jump start mode.

[0096] If U up -U down Less than U warn , or C DC If the DC is in working condition, it indicates that the vehicle was not woken up by jump-start, and the vehicle does not need to enter jump-start mode and can be used normally.

[0097] S4022, The vehicle control module calculates the required normal operating time T for the entire vehicle system. NR The vehicle's infotainment screen displays the amount of energy medium that needs to be replenished.

[0098] When energy needs to be replenished, the system calculates the amount required and displays the location of nearby charging facilities on the vehicle's screen to facilitate charging.

[0099] For example, typically after a jump start, the user still needs to press the key to wake the vehicle. However, the control method provided in this application requires no user operation; it is entirely controlled by the vehicle's control system, which determines whether to enter jump start mode and when to exit it. Please refer to [link to relevant documentation]. Figure 5 The jump-start mode requires the coordinated operation of the vehicle status monitoring module 51, energy management module 52, vehicle control module 50, charging system 53, and smart cockpit module 54. The vehicle control module 50, through the vehicle status monitoring module 51 and energy management module 52, compares the voltage value after recovery with the voltage value before entering the low-voltage shutdown state, as well as the operating status of the DC-DC device, to determine whether the vehicle was recovered via jump-start. If so, it automatically enters jump-start mode, controlling the operation of the charging system 53 and smart cockpit module 54 to prevent the vehicle from falling back into low voltage due to non-force majeure factors.
