[0086] This disclosure provides a method for vehicle control, wherein the subject executing the method can be the target vehicle. Figure 1 This is a schematic diagram of the structure of a target vehicle provided in an embodiment of this disclosure. From a hardware perspective, the structure of the target vehicle can be as follows: Figure 1 As shown, it includes a processor 110, a memory 120, a low-voltage load 130, and a display unit 140.

[0087] The processor 110 can be a central processing unit (CPU) or a system on chip (SoC), etc. The processor 110 can be used to process various operation instructions, such as obtaining the remaining power percentage of the low-voltage battery.

[0088] The memory 120 may include various volatile or non-volatile memories, such as solid-state disks (SSDs) and dynamic random access memory (DRAM). The memory 120 can be used to store initial data, intermediate data, and result data used in related processing, such as pre-storing the initial correspondence between limit levels and low-voltage load control information.

[0089] Low-voltage load 130 refers to various low-voltage loads of the target vehicle. The target vehicle supplies power to low-voltage load 140 via a low-voltage battery. Low-voltage load 140 may include speakers, blowers, heated steering wheels, heated seats, etc.

[0090] The display component 140 can be a standalone screen, or a screen integrated with the user equipment body, a projector, etc. The screen can be a touch screen or a non-touch screen (which can be displayed remotely), for example, displaying the upper limit of the low-voltage load 130.

[0091] This disclosure provides a method for vehicle control, such as... Figure 2 As shown, it includes the following steps:

[0092] 201, Obtain the remaining power percentage of the low-voltage battery.

[0093] The target vehicle may be equipped with a battery sensor to determine the remaining charge percentage of the low-voltage battery.

[0094] First, obtain the battery capacity error. When the capacity error is less than a threshold, obtain the remaining battery capacity percentage. For example, the capacity error threshold could be 10%. When the capacity error is less than 10%, obtain the remaining battery capacity percentage.

[0095] 202. Based on the correspondence between the range of remaining power percentage and the restriction level, determine the target restriction level corresponding to the target range of remaining power percentage.

[0096] The target vehicle can pre-store the correspondence between the range of remaining battery percentage and the restriction level. For example, as shown in Table 1, after obtaining that the remaining battery percentage of the low-voltage battery is 90%, the target restriction level corresponding to 90% can be found in Table 1 to be 1.

[0097] Table 1

[0098] Range of values ​​for remaining battery percentage Restriction Level [95,100] 0 [85,94] 1 …… ……

[0099] 203. Based on the first correspondence between the restriction level and the low-voltage load control information, determine the first low-voltage load control information corresponding to the target restriction level.

[0100] In the first correspondence, different low-voltage load control information is used to perform different energy-saving controls on the low-voltage load in the target vehicle.

[0101] The low-voltage load control information includes sub-control information for each low-voltage component. This sub-control information includes switch control information and / or gear limit, where the switch control information includes whether to allow or deny activation. Heated steering wheels and heated seats only have on / off operation, while blowers and speakers have multiple gear levels when activated; therefore, the low-voltage load control information for blowers and speakers includes gear limit.

[0102] The target vehicle can pre-store the first correspondence between the restriction level and the low-voltage load control information. For example, as shown in Table 2, restriction level 0 means that there is no need to control the low-voltage load for energy saving, and restriction level 1 means that the heated steering wheel and heated seats are turned on, and the blower and speaker are set to the maximum level of 3.

[0103] Table 2

[0104]

[0105] When the low-voltage load of the target vehicle includes a speaker, the first sub-control information corresponding to the speaker in the first correspondence includes switch control information and application information. The application information includes the applications that are allowed to use the speaker and the maximum allowed volume for each application.

[0106] 204. Based on the first low-voltage load control information, perform whole-vehicle control on the target vehicle.

[0107] Based on the first low-voltage load control information, the various low-voltage loads of the target vehicle are controlled. For example, if the first low-voltage load control information includes turning off the heated steering wheel and heated seats, and setting the blower and speaker settings to a maximum of level 2, then the control of the target vehicle is to turn off the heated steering wheel and heated seats, and set the blower and speaker settings to a maximum of level 2.

[0108] In one possible implementation, the instrument display processing flow can be as follows: Figure 3 As shown, it includes the following steps:

[0109] 301, The instrument panel display switch control information and / or gear limit of the target vehicle.

[0110] The target vehicle can display switch control information and / or gear limit on the instrument panel. For example, the instrument panel can display speaker switch control information and / or gear limit as follows: Figure 4 As shown, setting 0 indicates that the speaker is off, the pointer indicates the current setting of the speaker, and the "5" in the center of the pointer indicates the upper limit of the current setting.

[0111] 302. When the switch control information included in the first sub-control information in the first low-voltage load control information is refused to be turned on, determine the first low-voltage component corresponding to the first sub-control information and display the refused-to-turn-on indication information corresponding to the first low-voltage component.

[0112] When the first sub-control information includes switch control information that prohibits the opening of low-voltage loads, the instrument can display a prohibition indication message. This prohibition indication message can be achieved by dimming the indicator icon corresponding to the low-voltage load, changing the color of the indicator icon, etc. For example, to prohibit the speaker from being turned on, the instrument can display a prohibition indication message. Figure 4 The icon shown has dimmed.

[0113] 303. When the first low-voltage load control information contains second sub-control information including the gear limit, determine the second low-voltage component corresponding to the second sub-control information and display the gear limit indication information corresponding to the second low-voltage component.

[0114] Among them, the gear limit indication information is used to indicate the upper limit of the gears included in the second sub-control information.

[0115] When the second sub-control information includes the upper limit of the gear position, the instrument panel can display gear limit indication information. This information can include dimming the icon corresponding to gears exceeding the upper limit, changing the color of the icon corresponding to gears exceeding the upper limit, and so on. For example, when the upper limit of the speaker gear position is 3, it can... Figure 4 The icons corresponding to levels 4, 5, and 6 shown are dimmed.

[0116] In one possible implementation, the third sub-control information in the first low-voltage load control information includes switch control information indicating a refusal to open. This third sub-control information corresponds to a third low-voltage component. Upon receiving an open command, the corresponding processing flow can be as follows: Figure 5 As shown, it includes the following steps:

[0117] 501. When an opening command for the third low-voltage component is received, the opening command is refused to be executed.

[0118] 502 indicates a low battery alarm signal.

[0119] For example, the third low-voltage component is a heated seat. When a command to turn on the heated seat is received, if the switch control information included in the current low-voltage load control information indicates that the seat should not be turned on, the command to turn on will not be executed, and a low battery alarm signal may be issued. The alarm signal may be a flashing red light on the corresponding battery icon in the instrument panel, or an alarm sound from the speaker, etc.

[0120] In one possible implementation, the fourth sub-control information in the first low-voltage load control information includes the gear upper limit. This fourth sub-control information corresponds to the fourth low-voltage component. When a gear control command for the fourth low-voltage component is received, the corresponding processing flow can be as follows: Figure 6 As shown, it includes the following steps:

[0121] 601. When a gear control command for the fourth low-pressure component is received, if the gear corresponding to the gear control command is greater than the gear limit, the gear control command is refused to be executed, and the gear of the fourth low-pressure component is set in the fourth sub-control information including the gear limit.

[0122] 602, a low battery alarm signal is issued.

[0123] For example, the fourth low-pressure component is the blower. When a speed control command is received for the blower (the speed control command corresponds to speed 3), if the upper limit of the speed range included in the current low-pressure load control information is speed 2, the speed control command is rejected, the blower speed is set to speed 2, and a low battery alarm signal can be issued. The alarm signal can be a flashing red light on the corresponding battery icon on the instrument panel, or an alarm sound from the speaker, etc. If the upper limit of the speed range included in the current low-pressure load control information is speed 4, the speed control command is executed, and the blower speed is set to speed 3.

[0124] In one possible implementation, when the battery error exceeds a battery error threshold, the process for controlling the target vehicle can be as follows: Figure 7 As shown, it includes the following steps:

[0125] 701, obtain the voltage of the low-voltage battery.

[0126] The target vehicle may be equipped with a battery sensor to determine the voltage of the low-voltage battery.

[0127] 702. Based on the correspondence between voltage and limit level, determine the target limit level corresponding to the voltage of the low-voltage battery.

[0128] The target vehicle can pre-store the correspondence between voltage range and restriction level. For example, as shown in Table 3, after obtaining that the voltage of the low-voltage battery is 12 volts, the target restriction level corresponding to 12 volts can be found in Table 3 as 1.

[0129] Table 3

[0130] Voltage range Restriction Level [13,15] 0 [10,12] 1 …… ……

[0131] 703. Based on the second correspondence between the limit level and the low-voltage load control information, determine the second low-voltage load control information corresponding to the target limit level.

[0132] In the second correspondence, different low-voltage load control information is used to perform different energy-saving controls on the low-voltage load in the target vehicle.

[0133] The target vehicle can pre-store a second correspondence between the restriction level and the low-voltage load control information. For example, as shown in Table 4, restriction level 0 means that there is no need to control the low-voltage load for energy saving, and restriction level 1 means that the heated steering wheel and heated seats are turned on, and the blower and speaker are set to the maximum level of 3.

[0134] Table 4

[0135]

[0136] 704. Based on the second low-voltage load control information, perform whole-vehicle control on the target vehicle.

[0137] Based on the second low-voltage load control information, the various low-voltage loads of the target vehicle are controlled. For example, if the second low-voltage load control information includes turning off the heated steering wheel and heated seats, and setting the blower and speaker settings to a maximum of level 2, then the control of the target vehicle is to turn off the heated steering wheel and heated seats, and set the blower and speaker settings to a maximum of level 2.

[0138] In one possible implementation, the process for determining the operating power of each low-voltage load can be as follows: Figure 8 As shown, it includes the following steps:

[0139] 801. Based on the correspondence between the restriction level and the restriction power, determine the target restriction power corresponding to the target restriction level.

[0140] The target vehicle can pre-store the correspondence between the restriction level and the restricted power (the third correspondence). For example, as shown in Table 5, the target restricted power corresponding to the target restriction level can be determined in the third correspondence.

[0141] Table 5

[0142] Restriction Level Power limiting 0 90 watts 1 70 watts 2 50 watts …… ……

[0143] 802, determine the operating power of each low-voltage load currently in operation.

[0144] Obtain the voltage and current of each low-voltage load currently in operation, and calculate the operating power of each low-voltage load based on the voltage and current.

[0145] 803, calculate the sum of the operating power of each low-voltage load currently in operation to obtain the total operating power.

[0146] Sum the operating power of each low-voltage load to obtain the total operating power of all currently operating low-voltage loads. For example, A, B, and C are three currently operating low-voltage loads with operating power of 10 watts, 20 watts, and 30 watts, respectively. The total operating power is 60 watts.

[0147] 804. If the total operating power is greater than the target limit power, and the difference between the total operating power and the target limit power is greater than the difference threshold, then determine the ratio of the target limit power to the total operating power, calculate the product of the operating power of each low-voltage load currently in operation and the ratio, and obtain the adjusted operating power of each low-voltage load currently in operation.

[0148] For example, if the target limit level is 2, then the target limit power can be found in Table 5 to be 50 watts. The total operating power is greater than the target limit power, the difference between the total operating power and the target limit power is greater than the difference threshold, and the ratio of the target limit power to the total operating power is 5 / 6. The adjusted operating power for A, B, and C are 50 / 6, 50 / 3, and 25 watts, respectively.

[0149] 805 controls each low-voltage load currently in operation to operate at the adjusted operating power.

[0150] In this embodiment of the disclosure, the restriction level of the target vehicle is determined based on the current remaining power ratio. Different restriction levels have different power-saving controls for each low-voltage load. In this way, when the remaining power ratio of the low-voltage battery reaches a certain range, the power consumption of the low-voltage battery can be reduced by controlling the power saving of each low-voltage load, thereby reducing the possibility of the remaining power ratio becoming too low and reducing the situation of insufficient power supply from the low-voltage battery, thereby increasing the service life of the low-voltage battery and each low-voltage load.

[0151] All of the above-mentioned optional technical solutions can be combined in any way to form optional embodiments of this disclosure, and will not be described in detail here.

[0154] The determining module 920 is used to determine the target limit level corresponding to the target value range of the remaining power percentage based on the correspondence between the value range of the remaining power percentage and the limit level; and to determine the first low-voltage load control information corresponding to the target limit level based on the first correspondence between the limit level and the low-voltage load control information. In the first correspondence, different low-voltage load control information is used to perform different power-saving controls on the low-voltage loads in the target vehicle. Specifically, it can implement the processing functions of steps 202 and 203 above, as well as other implicit steps.

When the first low-voltage load control information includes second sub-control information that includes a gear limit, the device determines the second low-voltage component corresponding to the second sub-control information and displays the gear limit indication information corresponding to the second low-voltage component, wherein the gear limit indication information is used to indicate the gear limit included in the second sub-control information. Specifically, the processing functions of steps 301, 302, and 303 above, as well as other implicit steps, can be implemented.

[0158] In one possible implementation, the third sub-control information in the first low-voltage load control information includes switch control information indicating a refusal to enable, and this third sub-control information corresponds to a third low-voltage component.

[0167] In this embodiment of the disclosure, the restriction level of the target vehicle is determined based on the current remaining power ratio. Different restriction levels have different power-saving controls for each low-voltage load. In this way, when the remaining power ratio of the low-voltage battery reaches a certain range, the power consumption of the low-voltage battery can be reduced by controlling the power saving of each low-voltage load, thereby reducing the possibility of the remaining power ratio becoming too low and reducing the situation of insufficient power supply from the low-voltage battery, thereby increasing the service life of the low-voltage battery and each low-voltage load.
