Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to a whole vehicle battery charging control method, device, electronic equipment and storage medium. Background Art

[0002] In the case of frequent short-distance driving, such as driving about 2 kilometers each time, the amount of electricity replenished by the generator to the battery is often less than the amount of electricity consumed when starting the engine. This is because the vehicle may not have reached sufficient speed and time to effectively charge the battery for a short distance, and the starting process itself is a power-intensive operation. If this situation continues for a long time, that is, the vehicle is frequently operated in this mode (start-drive a short distance and then stop), the battery will gradually lose its stored energy and eventually become exhausted. When the battery is too low, it will not be able to provide enough power to start the engine again, which means that the vehicle may not start normally due to "battery power loss".

[0027] Combine the following Figure 1-Figure 5 The present invention describes a vehicle battery charging control method, device, electronic device and storage medium provided by an embodiment of the present invention.

[0028] Figure 1 This is one of the flow charts of the vehicle battery charging control method provided by the present invention; Figure 2 This is the second flow chart of the vehicle battery charging control method provided by the present invention; like Figure 1 and Figure 2 As shown, the method comprises the following steps: S110, when power-off and ignition-off are detected, obtaining a battery SOC value and an outdoor temperature; S120, determining a target SOC value based on the outdoor temperature; S130, if the battery SOC value is less than the target SOC value, controlling the generator to operate until the battery SOC value reaches the target SOC value; S140, controlling the vehicle to be powered off and turned off, and controlling the vehicle to be locked.

[0029] In the embodiment of the present invention, the execution subject of the vehicle battery charging control method may be a vehicle battery charging control device, and the voiceprint updating device may include but is not limited to vehicle-mounted electronic equipment, etc. The execution subject of the vehicle battery charging control method may also be a vehicle battery charging control system, and the vehicle battery charging control system belongs to the vehicle battery charging control device.

[0030] Figure 3 It is a structural schematic diagram of the vehicle battery charging control system provided by the present invention, such as Figure 3 As shown, the vehicle battery charging control system includes a battery 1, an EBS 2, an outdoor temperature sensor 3, an engine ECU 4, a start switch 5, a central control host 6, a display screen 7 and a T-BOX 8. For ease of understanding, the vehicle battery charging control system is used as the execution body to illustrate the vehicle battery charging control method provided by the present invention.

[0031] It should be noted that Figure 3 A schematic diagram of an example architecture that can be used is shown. For descriptive purposes, the architecture depicted is only an example of a suitable environment and is not intended to suggest any limitation on the scope of use or functionality of the present application.

[0032] In a specific implementation process, when the user presses the ignition switch and prepares to power off the engine, the engine ECU (Electronic Control Unit) 4 obtains the SOC (State of Charge) value of the battery 1 and the outdoor temperature value.

[0033] Specifically, in S110 , a signal of pressing the ignition switch is sent to the engine ECU 4 , and at the same time, the EBS (Electronic Brake System) collects the battery SOC value. After the outdoor temperature sensor 3 collects the outdoor temperature value, the battery SOC value and the outdoor temperature are also sent to the engine ECU 4 .

[0034] In S120, the target SOC value can be obtained according to the actual vehicle calibration, so as to more accurately determine the relationship between the battery SOC value and the outdoor temperature, and avoid the problem that the vehicle cannot be started even if the determination value is met due to determination failure. For example, the target SOC value of a certain vehicle model (i.e., the battery SOC value in the table) is shown in Table 1 below.

[0035] Table 1 Correspondence between outdoor temperature and target SOC value

[0036] In S130, if the collected battery SOC value is less than the target SOC value corresponding to the outdoor temperature, the generator is controlled to continue to work until the battery SOC value meets the target SOC value. Specifically: EBS2 continuously monitors the battery SOC value until the battery SOC value reaches the target SOC value and charging is completed, and sends information to the engine ECU to inform the engine ECU that the current battery SOC value has reached the preset value, so that the engine ECU can control the engine to shut down.

[0037] In S140 , after the battery SOC value reaches the target SOC value, the power is automatically turned off, the engine is shut down, and the vehicle is locked.

[0038] The vehicle battery charging control method provided by the embodiment of the present invention obtains the battery SOC value and outdoor temperature when power-off is detected; determines the target SOC value based on the outdoor temperature; if the battery SOC value is less than the target SOC value, controls the generator to work until the battery SOC value reaches the target SOC value; controls the vehicle to power off and lock the vehicle. When the user presses the ignition switch and prepares to power off, if it is detected that the battery SOC value is small, the engine is controlled to work until the battery SOC value reaches a preset value, and then the power is automatically turned off, the engine is turned off and the vehicle is locked, so as to charge the battery in time and prevent the battery from running low during short-distance and high-frequency driving.

[0039] In an optional embodiment, controlling the generator to operate until the battery SOC value reaches the target SOC value includes: Displaying an alarm message, wherein the alarm message is used to indicate that the battery SOC value is less than the target SOC value; After receiving the alarm information processing instruction, the generator is controlled to operate until the battery SOC value reaches the target SOC value.

[0040] Specifically, when the engine ECU 4 detects that the battery SOC value is less than the target SOC value, it sends a message to the central control host 6 through the CAN (Controller Area Network) line to inform the central control host 6 that the battery SOC value is low and needs to be charged. After receiving the message, the central control host 6 controls the display screen 7 to display an alarm message to remind the driver that the battery SOC value is low and needs to be charged.

[0041] Optionally, the alarm information is highlighted and flashes once every preset time period to prompt the user.

[0042] Furthermore, after the user chooses to process the alarm information, that is, after receiving the alarm information processing instruction, the generator is controlled to continue working until the battery SOC value reaches the target SOC value.

[0043] The vehicle battery charging control method provided by the embodiment of the present invention controls the generator to continue working to charge the battery only after the user confirms the processing of the alarm information, thereby determining whether to charge the battery according to the actual usage needs of the user.

[0044] In an optional embodiment, controlling the generator to operate until the battery SOC value reaches the target SOC value includes: Controlling the engine speed to change from a first value to a second value, wherein the second value is greater than the first value; Based on the second value, the engine is controlled to operate, and the generator is controlled to operate, until the battery SOC value reaches the target SOC value.

[0045] In the embodiment of the present invention, when the generator is working, the engine idle speed is controlled to increase to improve the charging efficiency. For example, the engine idle speed is controlled to increase from 800 rpm to 1200 rpm.

[0046] The vehicle battery charging control method provided by the embodiment of the present invention controls the engine idle speed to increase when the generator is working, thereby improving the battery charging efficiency.

[0047] In an optional embodiment, after controlling the generator to operate until the battery SOC value reaches the target SOC value, the method further includes: The charging result information is sent to a designated terminal device via the telematics control unit T-BOX, wherein the charging result information indicates that the battery SOC has reached the target SOC value.

[0048] In the embodiment of the present invention, after EBS2 detects that the battery SOC value has reached the target SOC value, the current battery SOC value is transmitted to the engine ECU4. The engine ECU4 determines that the battery SOC has reached the target SOC value, and sends the charging result information to T-BOX (Telematics Box, telematics control unit) 8 through a message. T-BOX8 sends a message to a designated terminal device to notify the vehicle owner that the battery has been fully charged and the vehicle has been automatically powered off and locked.

[0049] It is understandable that the designated terminal device is a terminal device that is bound to communicate with the vehicle, and may specifically include but is not limited to wearable devices, mobile phones, tablet computers, etc.

[0050] The vehicle battery charging control method provided in the embodiment of the present invention notifies the vehicle owner through the T-BOX after the battery charging is completed, so as to inform the vehicle owner that the battery has been charged and the vehicle has been automatically turned off and locked.

[0051] In an optional embodiment, the vehicle battery charging control method further includes: Determine a redundant SOC value based on the quiescent current and the estimated parking time; updating the target SOC value based on the sum of the redundant SOC value and the target SOC value; Based on the updated target SOC value, the generator is controlled to operate.

[0052] In the embodiment of the present invention, a redundant SOC value is calculated based on the static current and the estimated parking time of the vehicle, that is, the difference △SOC added to the target SOC value of the current charge. The battery is controlled to charge to the target SOC value + △SOC, thereby further ensuring that the battery is fully charged.

[0053] It can be understood that when the target SOC value+△SOC>100%, the target SOC value is updated to 100%.

[0054] It should be noted that the method for obtaining the estimated parking time is not limited here. For example, the vehicle parking time input by the user may be obtained, or the vehicle parking time may be determined based on the vehicle's historical driving record, or it may be a pre-set fixed value.

[0055] The vehicle battery charging control method provided in the embodiment of the present invention increases the preset target SOC value, which on the one hand ensures that the battery is charged to a sufficient amount of electricity, and on the other hand prolongs the battery power usage time, thereby extending the battery charging time interval, reducing the number of charging times, and extending the battery service life.

[0056] In an optional embodiment, the redundant SOC value is calculated based on the following formula: △SOC = I * t; Among them, △SOC represents the redundant SOC value, I represents the static current, and t represents the expected parking time.

[0057] The vehicle battery charging control method provided by the embodiment of the present invention determines the redundant SOC value according to the product of the static current and the expected parking time, thereby accurately calculating the chargeable electricity within the parking time.

[0058] Combine the following Figure 3 , the preferred vehicle battery charging control method of the present invention is described.

[0059] like Figure 3 As shown, EBS2 obtains the SOC value of battery 1 and transmits it to engine ECU4 through LIN (Local Interconnect Network) bus. Outdoor temperature sensor 3 transmits outdoor temperature to engine ECU4. When ignition switch 5 is pressed to power off and shut down, engine ECU4 determines whether the battery SOC value and outdoor temperature value meet the preset value. If not, the alarm signal is transmitted to central control host 6 through CAN bus, and the alarm message pops up on display screen 7. After selecting to process the alarm message, the generator continues to work until the battery SOC reaches the target SOC value, then the power is automatically turned off, the engine is shut down and the car is locked, and a message is sent to the owner through T-BOX8.
