Description

Technical Field

[0001] The present invention relates to the field of commercial vehicle power distribution technology, and in particular to a commercial vehicle power management method, device, electronic equipment and storage medium. Background Art

[0002] Current commercial vehicle equipment power consumption is generally divided into regular power and controlled power. Regular power refers to the power consumed by electrical equipment directly connected to the battery charging station, while controlled power refers to the power consumed after the main power switch. With the continuous upgrading of national emission regulations and the continuous development of intelligent connected technology, the number of controllers required in commercial vehicles has increased. At the same time, as drivers pursue greater comfort, high-power household electrical appliances such as parking air conditioners and inverters are gradually being used in commercial vehicles. Amidst technological upgrades and evolving needs, commercial vehicle power distribution has continued to accumulate on an existing basis, without major changes in power distribution solutions and power management. As battery discharge continues to plague drivers and electrical designers, they are also looking for better solutions, such as dual-battery or lithium-ion battery solutions. However, these solutions also result in a significant increase in vehicle costs and a decrease in vehicle competitiveness.

[0003] In practice, the following may be the reasons for battery depletion: due to the increase in the number of controllers, the static current consumption of the entire vehicle is getting larger and larger, which makes it easier for the battery to be depleted unknowingly; due to the increase in household electrical appliances, drivers are more likely to use these high-power electrical appliances when the vehicle is parked, which can easily cause the battery to be depleted; since most drivers do not have a deep understanding of the correct use of power, it is also easy for end users to cause battery depletion or shorten the life of the vehicle during use; when using dual power supply or lithium battery solutions, the cost will increase significantly; all of the above problems will cause the vehicle to fail to start or the vehicle purchase cost to increase, thereby affecting the vehicle's operating efficiency. Summary of the Invention

[0004] In view of this, it is necessary to provide a commercial vehicle power management method, device, electronic device and storage medium to solve the technical problem in the prior art that batteries are prone to power failure due to the conditional limitations of electrical equipment and electricity usage habits.

[0022] When the second rule is not satisfied, determining the power supply on / off status of the household electrical equipment and / or the controlled electrical equipment according to the relationship between the ambient temperature and the temperature threshold;

[0023] When the third rule is not satisfied, all electrical devices of different levels are classified and powered off.

[0027] In a possible implementation, the power protection mechanism includes a highest-level protection mechanism, a high-level protection mechanism, and a low-level protection mechanism determined according to power supply priority;

[0048] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0049] Due to the existing technical solutions, the permanent electrical equipment is directly connected to the battery, such as Figure 1 and Figure 2 As shown, the controlled electrical equipment is connected to the battery after passing through a mechanical power main switch or an electromagnetic power main switch. When the electromagnetic power main switch is used, a power control switch will be arranged in the cab to control the opening and closing of the electromagnetic power main switch. When the mechanical power main switch is used, the controlled electrical equipment is turned on and off by directly manually operating the power main switch. According to the power management requirements of commercial vehicles, when the driver leaves the vehicle, he should manually turn off the mechanical power main switch or the electromagnetic power main switch to reduce static current consumption. However, the above existing solutions have the following problems:

[0050] 1. The driver may forget to turn off the power switch. If the main power switch is not turned off, the battery will be depleted in 1-2 days, causing the engine to fail to start.

[0051] 2. Even if the main power switch is turned off, the vehicle will still have a static current of about 20mA-80mA, depending on the vehicle design status, which will still consume a lot of battery power. If the time is long enough, the battery will also be depleted;

[0052] 3. Due to the installation of high-power parking electrical equipment such as parking air conditioners, whether it is the receiving power control or the normal power end, if the driver operates it improperly, it is easy to cause the battery to run out of power.

[0053] Therefore, a specific embodiment of the present invention discloses a commercial vehicle power management method, see Figure 3 ,include:

[0054] S301. Classify the electrical equipment of the entire vehicle according to the electrical properties and electrical priorities of the equipment to obtain a plurality of electrical equipment classifications of different levels;

[0055] S302: according to preset rules, start or shut down the power supply to different types of electrical equipment;

[0056] S303: Obtain the number of passive power-offs for each category of electrical equipment, and determine a corresponding power protection mechanism according to the number of passive power-offs.

[0057] In this embodiment, the electrical equipment of the entire vehicle is first classified according to the power usage attributes and power usage priorities of the equipment, resulting in multiple different levels of electrical equipment classification; this ensures that the vehicle's critical systems always have sufficient power support, improving safety and reliability. Subsequently, the power supply and power outage of each electrical equipment classification is controlled according to preset rules; the system can automatically power off some non-critical equipment according to the rules to extend the use time of the remaining power and avoid excessive discharge of the battery. Finally, the number of passive power outages for each electrical equipment classification is obtained, and the corresponding power protection mechanism is determined based on the number of passive power outages. By recording the number of passive power outages for each electrical equipment classification, it is possible to understand which devices are frequently powered off, and then identify possible power management issues. Based on these records, the system can adjust the power protection mechanism to avoid excessive power outages of the battery, thereby reducing damage to the equipment and improving the durability of the battery and equipment.

[0058] In step S301, the device's power usage attributes refer to its power requirements and usage. These include the power required during normal operation and its current characteristics, specifically the potential for a higher current (startup current) required during startup and the stable current required during operation. These characteristics influence the device's power management strategy, including the device's operating status and duty cycle.

[0059] Furthermore, power priority means that when the power supply is limited, the equipment that still needs power after the vehicle is turned off will be given priority to be powered, based on the requirements of the vehicle system and the properties of the power-consuming equipment, and the power will be cut off for the equipment that can be selectively powered.

[0060] Furthermore, power distribution is intelligently adjusted based on device power requirements and urgency, ensuring that critical devices receive priority power support. In the event of insufficient power, non-critical devices are automatically powered off to extend battery life. This ensures that critical devices receive a stable power supply in all circumstances, thereby improving system security and reliability.

[0061] In step S302, the power supply and power outage of electrical equipment of different levels are controlled through preset rules, so that power management is more intelligent and efficient. Under different power states, power distribution can be automatically optimized according to the set rules to improve the stability and security of the system.

[0062] In step S303, determining a power protection mechanism based on the number of passive power outages can help the system identify and prevent potential power issues. For example, the system can set a higher protection level to prevent battery overdischarge or power system failure. This improves the reliability and stability of the power system and reduces the incidence of failures.

[0063] This intelligent power management eliminates the need for manual intervention in power system management and protection. The system automatically adjusts and optimizes power distribution, providing a better user experience. For example, when power is scarce, the system automatically ensures power supply to critical devices while reducing power consumption on non-critical devices.

[0064] In some embodiments, the multiple different levels of electrical equipment classification include:

[0065] Normally powered equipment directly connected to the positive pole of the battery, controlled electrical equipment that draws power from the main power switch, and household electrical equipment that draws power from the main power switch and can be powered off at any time when the vehicle is running or parked.

[0066] Specifically, permanent electrical equipment is equipment that needs to be powered continuously, or for a certain period of time, after the vehicle is parked and turned off. These include anti-theft systems, passive safety systems, key annunciators, and emergency power systems. Controlled electrical equipment is equipment that can be immediately powered off when the engine stops. Controlled electrical equipment includes interior lighting, seat heating and ventilation systems, and USB charging ports. Household electrical equipment is equipment that is added to increase vehicle comfort and is unrelated to vehicle operation. Household electrical equipment includes vehicle refrigerators, air conditioners, and audio systems. Permanent electrical equipment needs to be powered continuously under specific conditions (for a certain period of time after the vehicle is parked and turned off, depending on component requirements or regulatory requirements). Controlled electrical equipment cannot be powered off while the vehicle is running, but can be powered off after the vehicle is parked and turned off. Household electrical equipment can be powered off under any circumstances.

[0067] In order to maintain the battery's starting capability and automatic control functions, an electromagnetic main power switch needs to be added in front of each type of equipment. According to changes in environmental factors and intelligent network big data, the power manager can cut off the power supply of any circuit at any time according to the set power control strategy.

[0068] In a specific embodiment, see Figure 4 Electrical equipment is divided into three levels based on their importance: regular power equipment III-9, controlled power equipment III-7, and household power equipment III-4. When the vehicle needs to be powered off, household power, controlled power, and regular power are disconnected in that order. These three types of electrical equipment are collectively referred to as devices that share the same power supply properties.

[0069] Furthermore, the power manager III-10 and the IBS battery capacity sensor III-1 are directly connected to the battery and are not controlled by other devices. Only when the negative or positive terminal of the battery is disconnected will the power supply of these two devices be disconnected.

[0070] The power of electromagnetic main power switch #1 (III-5) is selected based on the total power of household electrical equipment #3-4. Electromagnetic main power switch #2 (III-6) is selected based on the total power of controlled electrical equipment #3-7. Electromagnetic main power switch #3 (III-8) is selected based on the total power of mains electrical equipment #3-9. Furthermore, to enhance the reliability of power connections to mains electrical equipment, electromagnetic main power switch #3 can also be replaced with an electronic relay.

[0071] The electromagnetic power main switch III-8 No. 3 is controlled by the power manager III-10 to be turned on or off. When the power manager III-10 outputs a low level, the electromagnetic power main switch No. 3 is turned on. Before the set power cut-off condition is met, the electromagnetic power main switch No. 3 remains in the on state.

[0072] Electromagnetic main power switches III-5 and III-6 are controlled by both power manager III-10 and power control switch III-3. When power control switch III-3 is on and power manager III-10 outputs a low level, electromagnetic main power switches III-1 and III-2 are turned on. If either condition is not met, electromagnetic main power switches III-3 and III-6 are turned off. Power control switch III-3 is manually turned on and off, while power manager III-10 determines whether to turn on the electromagnetic main power switches based on the voltage signal from the IBS battery charge sensor III-1 and the ambient temperature and speed signals from the EECU engine controller III-13. Before the set power-off condition is met, power control switch III-3 can be used to manually cut off the power supply to reduce power consumption under these conditions.

[0073] In some embodiments, the power supply to different types of electrical equipment is started or disconnected according to the preset rules. Figure 5 ,include:

[0074] S501, obtaining ambient temperature and engine speed;

[0075] S502, determining a first rule based on the relationship between the ambient temperature and the preset temperature;

[0076] S503, determining a second rule based on the relationship between the engine speed and the preset speed;

[0077] S504, and determining a third rule according to the magnitude relationship between the real-time voltage of the battery and the preset voltage;

[0078] S505: Start or shut down the power supply to different types of electrical equipment according to the first rule, the second rule, and the third rule.

[0079] In this embodiment, ambient temperature and engine speed parameters are introduced to optimize commercial vehicle power management by setting a series of rules and policies. For example, when the ambient temperature is below A, or when the engine speed is detected to be greater than B (indicating normal engine operation, this value can be calibrated), household electrical appliances are powered; otherwise, household electrical appliances remain powered off. When the battery voltage is below C, or when the engine speed is detected to be greater than B (indicating normal engine operation, this value can be calibrated), all devices are powered on.

[0080] Furthermore, the first rule is that the ambient temperature is greater than a preset temperature;

[0081] The second rule is that the engine speed is greater than a preset speed;

[0082] The third rule is that the real-time voltage of the battery is greater than the preset voltage;

[0083] When the second rule is met, power is supplied to all electrical equipment of different levels in a classified manner;

[0084] When the second rule is not satisfied, determining the power supply on / off status of the household electrical equipment and / or the controlled electrical equipment according to the relationship between the ambient temperature and the temperature threshold;

[0085] When the third rule is not satisfied, all electrical devices of different levels are classified and powered off.

[0086] Based on the judgment logic of the above-mentioned different rules, it should be noted that the preset speed represents the speed of normal engine operation. The preset temperatures include a first preset temperature and a second preset temperature. When the second rule is not met, the power supply on / off status of the household electrical equipment and / or the controlled electrical equipment is determined based on the relationship between the ambient temperature and the temperature threshold. When the speed is lower than the preset speed (i.e., the engine is in an abnormal operating state), the first preset temperature and the second preset temperature are used to determine whether to disconnect the controlled electrical equipment and the household electrical equipment simultaneously, or only the household electrical equipment.

[0087] Furthermore, the preset voltage includes multiple voltage levels. Under different voltage levels, the power supply start and stop conditions of normal power equipment, controlled power equipment and household power equipment are different, such as Figure 4 As shown, in a specific embodiment, the power management principle of the power manager III-10 is:

[0088] When the power manager III-10 detects that the engine speed is ≥500rpm, the pins connected to the power manager III-10 and the three electromagnetic power switches can output a low level;

[0089] When the engine speed is 0, the ambient temperature < -25°C (this value can be calibrated), and it lasts for 1 minute, the pin of the power manager III-10 connected to the No. 1 electromagnetic main power switch cannot output a low level, and the domestic electrical equipment is powered off.

[0090] When the engine speed is 0, the ambient temperature < -40°C (this value can be calibrated), and it lasts for 1 minute, the pins of the power manager III-10 connected to the No. 1 and No. 2 electromagnetic main power switches cannot output a low level, and the domestic electrical equipment and the controlled electrical equipment are powered off.

[0091] When the power manager III-10 detects that the battery voltage ≥ X1V and it lasts for 1 minute, the pins of the power manager III-10 connected to the 3 electromagnetic main power switches can all output a low level;

[0092] When the power manager III-10 detects that the battery voltage ≥ X2V and it lasts for 1 minute, the pins of the power manager III-10 connected to the No. 2 and No. 3 electromagnetic main power switches can all output a low level;

[0093] When the power manager III-10 detects that the battery voltage ≥ X3V and it lasts for 1 minute, the pin of the power manager III-10 connected to the No. 3 electromagnetic main power switch can output a low level;

[0094] When the power manager III-10 detects that the battery voltage < X3V and it lasts for 1 minute, the pins of the power manager III-10 connected to the 3 electromagnetic main power switches cannot output a low level. That is, at this time, all electrical equipment except the power manager III-10 and the IBS battery charge sensor III-1 will be powered off to avoid the vehicle from not starting due to the battery being discharged.

[0095] When the above conditions are met, the on or off action is executed; otherwise, the reverse action is executed. In this description, X1 > X2 > X3 (this value can be calibrated).

[0096] In some embodiments, obtaining the passive power-off times of each electrical equipment classification and determining the corresponding power protection mechanism according to the passive power-off times includes:

[0097] Determining the protection mechanisms of each electrical equipment classification under different passive power-off times according to the influence degree of the passive power-off times of the electrical equipment classification on vehicle operation and battery management;

[0098] Determining the control strategy according to the protection mechanisms of each electrical equipment classification under different passive power-off times.

[0099] In this embodiment, the power manager collects and records the number of passive power outages for each type of electrical device, sends the data to the T-BOX, and then uploads it to the cloud. When the number of passive power outages reaches a specified threshold, the power manager takes appropriate action and pushes relevant information and commands to the driver via a mobile app in the form of a message.

[0100] In a specific embodiment, Figure 4 As shown, the power manager is connected to the T-BOX via the CAN bus. The power manager monitors and records the number of forced power outages (when the trigger voltage is less than X, causing the power manager to proactively shut down) for each device. The power manager then sends this data to the T-BOX via the CAN bus, which then uploads it to the cloud. The power manager triggers the power protection mechanism based on the number of power outages for each device over a period of time.

[0101] Further, such as Figure 4 As shown, before each electrical device automatically powers off, the Power Manager III-10 issues an alarm and text prompt via the bus. Voice alarms can be heard via the right-turn warning tone III-11, and buzzer and text prompts can be heard via the instrument panel III-12, reminding the driver to start the engine or connect an external power source immediately. To prevent unforeseen power outages, the alarm function should last approximately two minutes (this value is calibrable). In certain circumstances, if the Power Manager shuts off all power, power to the starting circuit is also cut off. To prevent the driver from starting the engine, a power reset switch III-14 can be configured. By pressing this reset switch III-14, the Power Manager III-10 forcibly restores power to the electromagnetic main power switches No. 2 and No. 3 for a period of five minutes (this value is calibrable), ensuring sufficient time for the driver to start the engine.

[0102] In a specific embodiment, the specific logic of the power protection mechanism is shown in Table 1:

[0103] Table 1: Power protection mechanism trigger logic table

[0104]

[0105] It should be noted that the first preset time is N+20 days, the second preset time is N+10 days, and the third preset time is N+5 days.

[0106] Based on the above commercial vehicle power management method, the embodiment of the present invention also provides a commercial vehicle power management device, see Figure 6 ,include:

The memory 720 is used to store application software installed in the electronic device and various types of data, such as program code installed in the electronic device.

In one embodiment, the memory 720 stores a commercial vehicle power management program 740, which can be executed by the processor 710 to implement the commercial vehicle power management method of each embodiment of the present application.
