Description

Technical Field

[0001] This application relates to the field of automotive electronics and electrical technology, and in particular to a method, device, vehicle, and storage medium for controlling vehicle load. Background Technology

[0002] During vehicle operation, the load power consumption varies depending on the usage scenario. If the vehicle is to meet the extreme high power consumption scenarios that may occur, the generator matched with the vehicle will need to be very large, which will increase the cost of the vehicle and reduce its cost-effectiveness. If the vehicle is not to meet the extreme high power consumption scenarios, the generator may not be able to meet the power demand during operation, resulting in battery depletion and breakdown.

[0003] In related technologies, a power level warning system can promptly notify users of the current power level, allowing them to adjust the vehicle's power consumption accordingly.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] The following description, with reference to the accompanying drawings, outlines a vehicle load control method, apparatus, vehicle, and storage medium according to embodiments of this application. Addressing the issues raised in the background section regarding related technologies where users are distracted by adjusting the load of vehicle electrical components after a battery warning, which is detrimental to driving safety and requires users to expend energy identifying activated electrical components, thus impacting the driving experience, this application provides a vehicle load control method. This method monitors the vehicle's onboard battery status in real time, collects current battery data to match the vehicle's actual load level, and determines the optimal load control strategy based on the actual load level. This limits the power consumption of vehicle electrical components without requiring user intervention to adjust their load, ensuring stable power supply and safe driving even under extremely high power consumption. Therefore, this method solves the technical problems in related technologies where users are distracted by adjusting the load of vehicle electrical components after a battery warning, which is detrimental to driving safety and requires users to expend energy identifying activated electrical components, thus impacting the driving experience.

[0030] Specifically, Figure 1 This is a flowchart illustrating a vehicle load control method provided in an embodiment of this application.

[0031] like Figure 1 As shown, the vehicle load control method includes the following steps:

[0032] In step S101, the current battery data of the vehicle's on-board battery is collected.

[0033] In actual implementation, the embodiments of this application can use vehicle sensors to collect real-time battery data of the vehicle battery, including the power battery and the storage battery, so as to facilitate subsequent power adjustment of electrical devices based on the current battery data.

[0034] Optionally, in one embodiment of this application, the battery data includes the battery state of charge, state of charge error, battery charge / discharge current, and / or battery charge / discharge voltage.

[0035] The battery data can include the battery state of charge, state of charge error, battery charging and discharging current and / or battery charging and discharging voltage, thereby allowing information such as the battery's current state, load status and power level to be obtained based on the battery data.

[0036] In step S102, the actual load level of the vehicle is matched according to the current battery data, and the optimal load control strategy of the vehicle is determined according to the actual load level.

[0037] As one possible implementation, embodiments of this application can match the actual load level of the vehicle based on the obtained current battery data, thereby determining the optimal load control strategy for the vehicle based on the actual load level. For example, embodiments of this application can limit the power consumption of most electrical devices when the actual load level is high, and limit the power consumption of a small number of electrical devices when the actual load level is low. The division of the actual load level and the optimal load control strategy will be described below.

[0038] Optionally, in one embodiment of this application, determining the optimal load control strategy for the vehicle based on the actual load level includes: when the battery state of charge (SBC) is greater than or equal to a first preset lower limit and the SBC error is within a first preset range, the current load level of the vehicle is Level 1; when the battery SBC is lower than the first preset lower limit, the battery is in a continuous discharge state for a first preset duration and the SBC error is within a first preset range, the current load level of the vehicle is Level 2; when the battery SBC is lower than a second preset lower limit, the battery is in a continuous discharge state for a first preset duration and the SBC error is within a first preset range, the current load level of the vehicle is Level 3, wherein the second preset lower limit is less than the first preset lower limit; when the battery SBC is lower than a third preset lower limit, the battery is in a continuous discharge state for a first preset duration and the SBC error is within a first preset range, the current load level of the vehicle is Level 4, wherein the third preset lower limit is less than the second preset lower limit.

[0039] In some embodiments, when the battery state of charge is greater than or equal to a first preset lower limit and the state of charge error is within a first preset range, such as within ±10%, it indicates that the current battery load of the vehicle is good and can maintain the normal operation of the vehicle and ensure the vehicle's range. At this time, the current load level of the vehicle is level one.

[0040] When the battery state of charge is lower than the first preset lower limit, and the battery is in a continuous discharge state for a first preset time period, such as 120 seconds, that is, the current value emitted by the battery sensor is negative for 120 seconds, and the state of charge error is within the first preset range, such as ±10%, the current load level of the vehicle is level two.

[0041] When the battery state of charge is lower than the second preset lower limit, if the battery is in a continuous discharge state for 120 seconds within the first preset time period, that is, the current value emitted by the battery sensor is negative for 120 seconds, and the state of charge error is within the first preset range, such as within ±10%, the current load level of the vehicle is level three.

[0042] When the battery state of charge is lower than the third preset lower limit, if the battery is in a continuous discharge state for 120 seconds within the first preset time period, that is, the current value emitted by the battery sensor is negative for 120 seconds, and the state of charge error is within the first preset range, such as within ±10%, the current load level of the vehicle is level four.

[0043] Wherein, the first preset lower limit is less than the second preset lower limit, the second preset lower limit is less than the third preset lower limit, and the first preset lower limit, the second preset lower limit, the third preset lower limit, the first preset duration, and the first preset range can all be set by those skilled in the art based on data such as the actual capacity of the battery, the battery charging and discharging current, and / or the battery charging and discharging voltage, without any specific restrictions here.

[0044] Optionally, in one embodiment of this application, determining the optimal load control strategy for the vehicle based on the actual load level further includes: when the state of charge error is within a second preset range and the battery is in a charging state, if the battery voltage is continuously higher than a preset voltage threshold for a second preset duration, the current load level of the vehicle is level one; when the state of charge error is within a second preset range and the battery is in a discharging state, if the battery voltage is continuously lower than a preset voltage threshold for a second preset duration, the current load level of the vehicle is level four.

[0045] In other embodiments, when the state of charge error is within a second preset range, such as when the state of charge error is greater than 15% and the battery is in a charging state, if the battery voltage is continuously higher than a preset voltage threshold for a second preset duration, the current load level of the vehicle is level one.

[0046] When the state of charge error is within the second preset range, such as when the state of charge error is greater than 15% and the battery is in a discharging state, if the battery voltage remains below the preset voltage threshold for a second preset duration, the current load level of the vehicle is level four.

[0047] The second preset range, the second preset duration, and the preset voltage threshold can be set by those skilled in the art based on data such as the actual capacity of the battery, the battery charging and discharging current, and / or the battery charging and discharging voltage, and no specific restrictions are imposed here.

[0048] In step S103, based on the optimal load control strategy, at least one electrical component of the vehicle is controlled to consume power under the power consumption limit corresponding to the actual load level.

[0049] In actual implementation, the embodiments of this application can control the power consumption of the electrical components of the vehicle under the power consumption limit corresponding to the actual load level based on the optimal load control strategy, thereby automatically limiting the power consumption of the electrical components, extending the vehicle battery range, eliminating the need for user distraction, ensuring vehicle driving safety, and improving the user experience.

[0050] Optionally, in one embodiment of this application, based on an optimal load control strategy, controlling at least one electrical component of the vehicle to consume power under the power consumption limit corresponding to the actual load level includes: when the current load level is Level 1, maintaining the current load state of the electrical component; when the current load level is Level 2, controlling the load of the electrical component to be lower than or equal to a first percentage of the full load of the electrical component; when the current load level is Level 3, controlling the load of the electrical component to be lower than or equal to a second percentage of the full load of the electrical component; and when the current load level is Level 4, controlling the load of the electrical component to be lower than or equal to a third percentage of the full load of the electrical component.

[0051] As one possible implementation, this application embodiment can determine that the vehicle battery's range is good when the current load level is Level 1, without needing to limit the power consumption of currently operating electrical components. In this case, the electrical components maintain their current load state.

[0052] This application embodiment can control the load of electrical devices to be lower than or equal to a first percentage of the full load of the electrical devices when the current load level is level two. For example, it can limit the electrical devices related to comfort: seat heating and PTC (Positive Temperature Coefficient) will be adjusted to a low level. If they were originally at a low level or not turned on, they will remain unchanged. The air conditioning module controls the blower air volume to 75%. If it was originally at 75% or lower, it will remain unchanged. At the same time, the instrument panel will prompt the user with "Friendly reminder: Comfort and entertainment functions are limited. They will be automatically restored after the battery is charged".

[0053] This application embodiment can control the load of electrical devices to be lower than or equal to a second percentage of the full load of the electrical devices when the current load level is three. For example, it can limit or turn off electrical devices related to comfort: seat heating, PTC and steering wheel heating will be adjusted to the off position, and if they were originally off, they will remain unchanged; the air conditioning module will control the blower air volume to 50%, and if it was originally 50% or lower, it will remain unchanged; the amplifier or audio entertainment module will reduce the speaker volume to 50%, and if the volume was originally 50% or lower, it will remain unchanged. At the same time, the instrument panel will prompt the user with "Friendly reminder: comfort and entertainment functions are limited and will be automatically restored after the battery is charged".

[0054] This application embodiment can control the load of electrical devices to be lower than or equal to the third percentage of the full load of the electrical devices when the current load level is level four. For example, it can limit or turn off electrical devices related to comfort: seat heating, PTC and steering wheel heating will be adjusted to the off position, and if they were originally off, they will remain unchanged; the air conditioning module will control the blower air volume to 25%, and if it was originally 25% or lower, it will remain unchanged; the amplifier or audio entertainment module will reduce the speaker volume to 25%, and if the volume was originally 25% or lower, it will remain unchanged. At the same time, the instrument panel will prompt the user with "Friendly reminder: comfort and entertainment functions are limited and will be automatically restored after the battery is charged".

[0055] The first percentage, the second percentage, and the third percentage can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0056] Optionally, in one embodiment of this application, after controlling at least one electrical component of the vehicle to consume power under the power consumption limit corresponding to the actual load level based on the optimal load control strategy, the method further includes: acquiring the battery state of charge every third preset time interval; determining whether the battery state of charge meets preset change conditions based on the amount of change in the battery state of charge; and if the battery state of charge meets the preset change conditions, then re-matching the actual load level of the vehicle.

[0057] Furthermore, embodiments of this application can monitor the vehicle battery in real time so that the actual load level of the vehicle can be readjusted after the battery state of charge changes.

[0058] Specifically, in this application embodiment, battery state of charge (SOC) data can be acquired at each third preset time interval. Then, based on the amount of change in SOC, such as changes in SOC caused by charging or discharging, it can be determined whether the battery SOC meets preset modification conditions. If the preset modification conditions are met, the actual load level of the vehicle can be rematched. For example, if the SOC increases due to charging, the load level can be increased if the preset modification conditions are met. If the SOC decreases due to discharging, the load level can be decreased if the preset modification conditions are met.

[0059] For example, when the current load level is level 2, if the battery state of charge recovers to 2% above the first preset lower limit, this embodiment of the application can adjust the load level to level 1; when the current load level is level 3, if the battery state of charge recovers to 2% above the second preset lower limit, this embodiment of the application can adjust the load level to level 2; when the current load level is level 4, if the battery state of charge recovers to 2% above the third preset lower limit, this embodiment of the application can adjust the load level to level 3.

[0060] Combination Figure 2 and Figure 3As shown, the working principle of the vehicle load control method of this application embodiment is explained in detail with reference to one embodiment.

[0061] like Figure 2 As shown, taking a storage battery as an example, this application embodiment can use a storage battery sensor to obtain the battery's SOC (State of Charge), SOC state (SOC error), current, and voltage, and use a load control module to limit the power consumption of electrical devices such as instruments, steering wheel heating modules, seat heating modules, PTC, air conditioning modules IHU / amplifiers.

[0062] Specifically, such as Figure 3 As shown, embodiments of this application can classify the load levels of vehicles, wherein, Figure 3 In this application, level 0 is the first level, level 1 is the second level, level 2 is the third level, and level 3 is the fourth level.

[0063] When the battery SOC is not lower than the first lower limit and the SOC error range is within ±10%, the load control module issues a load limit level of 0, at which point all loads are unrestricted.

[0064] When the battery's State of Charge (SOC) is below the first lower limit and the SOC error range is within ±10%, and the battery is continuously discharging for 120 seconds (i.e., the current value emitted by the battery sensor is negative for 120 seconds), the load control module sends a load limitation level of level 1 via CAN (Controller Area Network) signal. Upon receiving this signal, the relevant comfort load modules adjust the seat heating and PTC functions to a lower setting (if they were already at a lower setting or not activated, they remain unchanged). The air conditioning module controls the blower airflow to 75% (if it was already at 75% or below, it remains unchanged). Simultaneously, the instrument panel displays a message: "Friendly reminder: Comfort and entertainment functions are limited; they will automatically recover after battery charging." If the SOC recovers to 2% above the first lower limit, the limitation level reverts to level 0.

[0065] When the battery's State of Charge (SOC) falls below the second lower limit and the SOC error range is within ±10%, and the battery remains in a discharging state for 120 seconds, the load control module sends a load limitation level of 2 via CAN signal. Upon receiving this signal, the relevant comfort load modules will adjust the seat heating, PTC, and steering wheel heating to the off position (if they were already off, they will remain unchanged). The air conditioning module will control the blower fan speed to 50% (if it was already at or below 50%, it will remain unchanged). The amplifier or audio entertainment module will reduce the speaker volume to 50% (if it was already at or below 50%, it will remain unchanged). Simultaneously, the instrument panel will display a message: "Friendly reminder: Comfort and entertainment functions are limited; they will automatically recover after the battery is charged." If the SOC recovers to 2% above the second lower limit, the limitation level will revert to level 1.

[0066] When the battery's State of Charge (SOC) falls below the third lower limit and the SOC error range is within ±10%, and the battery remains in a discharging state for 120 seconds, the load control module sends a load limitation level of 3 via CAN signal. Upon receiving this signal, the relevant comfort load modules will adjust the seat heating, PTC, and steering wheel heating to the off position (if they were already off, they will remain unchanged). The air conditioning module will control the blower fan speed to 25% (if it was already at or below 25%, it will remain unchanged). The amplifier or audio entertainment module will reduce the speaker volume to 25% (if it was already at or below 25%, it will remain unchanged). Simultaneously, the instrument panel will display a message: "Friendly reminder: Comfort and entertainment functions are limited; they will automatically recover after the battery is charged." If the SOC recovers to 2% above the third lower limit, the limitation level will revert to level 2.

[0067] When the battery SOC error range is greater than 15% and the battery is in a charging state, the load control module determines the limit level based on the battery voltage. If the battery voltage continues to be higher than the threshold for 120 seconds, the load control module sends a load limit level of level 0 via CAN signal, at which point all loads are unrestricted.

[0068] When the battery's State of Charge (SOC) error is greater than 15% and the battery is discharging, the load control module determines the limitation level based on the battery voltage. If the battery voltage remains below the threshold for 120 seconds, the load control module sends a load limitation level of level 3 via CAN signal. Upon receiving this signal, the relevant comfort load modules will adjust the seat heating, PTC, and steering wheel heating to the off position (if they were already off, they will remain unchanged). The air conditioning module will control the blower fan speed to 25% (if it was already at or below 25%, it will remain unchanged). The amplifier or audio entertainment module will reduce the speaker volume to 25% (if it was already at or below 25%, it will remain unchanged). Simultaneously, the instrument panel will display a message: "Friendly reminder: Comfort and entertainment functions are limited; they will automatically recover after the battery is charged." If the voltage recovers above the threshold, the limitation level will revert to level 0.

[0069] The vehicle load control method proposed in this application can monitor the vehicle's on-board battery status in real time, collect the current battery data of the vehicle's on-board battery to match the actual load level of the vehicle, and thus determine the optimal load control strategy for the vehicle based on the actual load level. This limits the power consumption of the vehicle's electrical components without requiring the user to adjust the load of these components, ensuring the stability of the vehicle's power supply and safe driving under extremely high power consumption conditions. Therefore, this solves the technical problems in related technologies where users need to be distracted to adjust the load of vehicle electrical components after a battery warning, which is detrimental to driving safety, and where users need to expend energy to identify activated electrical components, affecting the user's driving experience.

[0073] Specifically, the acquisition module 100 is used to acquire the current battery data of the vehicle's on-board battery.

The second preset lower limit is less than the first preset lower limit.

[0081] The fourth determining unit is used to determine the current load level of the vehicle as level four when the battery state of charge is lower than the third preset lower limit, the battery is in a continuous discharge state for a first preset time period, and the state of charge error is within the first preset range. The third preset lower limit is less than the second preset lower limit.

[0082] Optionally, in one embodiment of this application, the matching module 200 further includes a fifth determining unit and a sixth determining unit.

[0083] The fifth determining unit is used to determine the current load level of the vehicle as Level 1 when the state of charge error is within a second preset range and the battery is in a charging state, and the battery voltage is continuously higher than a preset voltage threshold for a second preset time period.

[0084] The sixth determining unit is used to determine the current load level of the vehicle as level four when the state of charge error is within a second preset range and the battery is in a discharging state, and the battery voltage is continuously lower than a preset voltage threshold for a second preset time period.

[0085] Optionally, in one embodiment of this application, the control module 300 includes: a first control unit, a second control unit, a third control unit, and a fourth control unit.

[0086] The first control unit is used to maintain the current load state of the electrical components when the current load level is level one.

[0087] The second control unit is used to control the load of the electrical device to be lower than or equal to a first percentage of the full load of the electrical device when the current load level is level two.

[0088] The third control unit is used to control the load of the electrical device to be lower than or equal to a second percentage of the full load of the electrical device when the current load level is level three.

[0089] The fourth control unit is used to control the load of the electrical device to be lower than or equal to the third percentage of the full load of the electrical device when the current load level is level four.

[0090] Optionally, in one embodiment of this application, the vehicle load control device 10 further includes: an acquisition module, a judgment module, and a rematching module.

[0091] The acquisition module is used to acquire the battery state of charge every third preset time interval.

[0092] The judgment module is used to determine whether the battery state of charge meets the preset change conditions based on the amount of change in the battery state of charge.

[0093] The re-matching module is used to re-match the vehicle's actual load level when the battery state of charge meets preset change conditions.

[0094] It should be noted that the foregoing explanation of the vehicle load control method embodiment also applies to the vehicle load control device of this embodiment, and will not be repeated here.

[0095] The vehicle load control device proposed in this application can monitor the vehicle's on-board battery status in real time, collect the current battery data of the vehicle's on-board battery to match the actual load level of the vehicle, and thus determine the optimal load control strategy for the vehicle based on the actual load level. This limits the power consumption of the vehicle's electrical components without requiring the user to adjust the load of these components, ensuring the stability of the vehicle's power supply and safe driving under extremely high power consumption conditions. Therefore, this solves the technical problems in related technologies where users need to be distracted to adjust the load of vehicle electrical components after a battery warning, which is detrimental to driving safety, and where users need to expend energy to identify activated electrical components, affecting the user's driving experience.
