[0002] The electricity used by existing commercial vehicle equipment is generally divided into normal electricity and controlled electricity. Normal electricity refers to the electricity used by electrical equipment directly connected to the battery pile, and controlled electricity refers to the electricity used after passing through the main power switch. With the continuous upgrading of national emission regulations and the continuous development of intelligent network technology, the number of controllers required for commercial vehicles is increasing. At the same time, with the pursuit of comfort by drivers, high-power household electrical equipment such as parking air conditioners and inverters are gradually being applied to commercial vehicles. In the process of technological upgrading and demand evolution, commercial vehicle power distribution has continued to accumulate on the previous basis, without taking a major change in the design of power distribution solutions and commercial vehicle power management. When the problem of battery power loss continues to bother drivers and electrical designers, they are also looking for better solutions, such as dual battery solutions or lithium battery solutions, but these solutions have also caused a significant increase in vehicle costs and a decline 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 vehicle is getting larger and larger, which makes it easier to cause the battery to deplete without knowing it; due to the increase in household electrical appliances, drivers are more likely to use these high-power electrical appliances when parking, which can easily cause the battery to deplete; 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 their life during the use of the vehicle; when using dual power or lithium battery solutions, the cost will increase significantly; all of the above problems will cause the vehicle to fail to start or the cost of purchasing the vehicle to increase, thereby affecting the vehicle's operating efficiency. Summary of the invention

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are 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, but are not used to limit the scope of the present invention.

[0018] Due to the existing technical solutions, the permanent electrical equipment is directly connected to the battery, such as Figure 1 and Figure 2As 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 an 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 a 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, the mechanical power main switch or the electromagnetic power main switch should be manually turned off to reduce static current consumption. However, the above existing solutions have the following problems: 1. The driver tends to 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; 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 lose power; 3. Due to the installation of high-power parking electrical equipment such as parking air conditioners, whether it is the receiving control power or the normal power end, if the driver operates it improperly, it is easy to cause the battery to run out of power.

[0019] Therefore, a specific embodiment of the present invention discloses a commercial vehicle power management method, see Figure 3 ,include: S301, classifying the electrical equipment of the vehicle according to the electrical properties and electrical priorities of the equipment to obtain a plurality of electrical equipment classifications of different levels; S302, according to preset rules, starting or disconnecting the power supply to different types of electrical equipment; S303: Obtain the number of passive power-offs of each electrical equipment category, and determine a corresponding power protection mechanism according to the number of passive power-offs.

[0020] In this embodiment, the electrical equipment of the whole vehicle is first classified according to the power consumption attributes and power consumption priorities of the equipment to obtain multiple different levels of electrical equipment classification; thereby ensuring that the key systems of the vehicle always have sufficient power support to improve safety and reliability. Subsequently, according to the preset rules, the power supply and power off of each electrical equipment classification are controlled; 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 offs of each electrical equipment classification is obtained, and the corresponding power protection mechanism is determined according to the number of passive power offs. By recording the number of passive power offs of each electrical equipment classification, it is possible to understand which devices are frequently powered off, and then identify possible power management problems. Based on these records, the system can adjust the power protection mechanism to avoid excessive and frequent power off of the battery, thereby reducing damage to the equipment and improving the durability of the battery and the equipment.

[0021] In step S301, the power usage attributes of the device refer to the power demand characteristics and usage of the device. They include: the power required by the device during normal operation, the current characteristics of the device, specifically, the device may require a higher current (start-up current) when starting up and the stable current required during operation. These characteristics will affect the power management strategy of the device. The operating status and working cycle of the device.

[0022] 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 powered first, based on the requirements of the vehicle system and the properties of the power-consuming equipment, and the equipment that can be selectively powered will be powered off.

[0023] Furthermore, according to the power demand and urgency of the equipment, the power distribution is intelligently adjusted to ensure that important equipment is given priority in power support. In the case of insufficient power, non-critical equipment is automatically powered off to extend battery life. This ensures that critical equipment can obtain stable power in any situation, thereby improving the safety and reliability of the system.

[0024] In step S302, 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. Power distribution can be automatically optimized according to set rules under different power states to improve system stability and security.

[0025] In step S303, determining the power protection mechanism based on the number of passive power outages can help the system identify and prevent potential power problems. For example, the system can set a higher protection level to prevent excessive battery discharge or power system failure. In this way, the reliability and stability of the power system can be improved and the failure rate can be reduced.

[0026] Through intelligent power management, users do not need to manually intervene in the management and protection of the power system. The system can automatically adjust and optimize power distribution to provide a better user experience. For example, when power is tight, the system will automatically ensure the power supply of key devices while reducing the power consumption of non-key devices.

[0027] In some embodiments, the multiple different levels of electrical equipment classification include: 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.

[0028] Specifically, the permanent electrical equipment refers to the equipment that needs to be powered on all the time or for a certain period of time after the vehicle is parked and turned off, including anti-theft systems, passive safety systems, key annunciators, and emergency power supply systems. Controlled electrical equipment refers to the equipment that can be powered off immediately when the engine stops, including interior lighting, seat heating and ventilation systems, and USB charging ports. Daily electrical equipment refers to the equipment that is added to increase the comfort of the vehicle and is not related to the operation of the vehicle, including vehicle refrigerators, air conditioners, and audio systems. The permanent electrical equipment needs to be powered on all the time under specific conditions (all the time or for a certain period of time after the vehicle is parked and turned off, according to parts requirements or regulatory requirements). The controlled electrical equipment cannot be powered off when the vehicle is running, but can be powered off after the vehicle is parked and turned off. Daily electricity can be powered off under any circumstances.

[0029] In order to maintain the battery's starting capability and automatic control function, an electromagnetic main power switch must 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 consumption of any circuit at any time according to the set power control strategy.

[0030] In a specific embodiment, see Figure 4 According to the importance of electrical equipment, electrical equipment is divided into three levels: normal electrical equipment III-9, controlled electrical equipment III-7, and life electrical equipment III-4. When the vehicle needs to be powered off, the life power, controlled power, and normal power are disconnected in turn. The three types of electrical equipment are a general term for a class of equipment that uses the same power source attribute.

[0031] 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 pole of the battery is disconnected, the power supply of these two devices will be disconnected.

[0032] The power of the No. 1 electromagnetic power main switch III-5 is selected according to the total power of the household electrical equipment III-4, the No. 2 electromagnetic power main switch III-6 is selected according to the total power of the controlled electrical equipment III-7, and the No. 3 electromagnetic power main switch III-8 is selected according to the total power of the normal electrical equipment III-9. Furthermore, in order to enhance the power connection reliability of the normal electrical equipment, the No. 3 electromagnetic power main switch can also be replaced by an electronic relay.

[0033] The electromagnetic power main switch No. 3 III-8 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 conditions are met, the electromagnetic power main switch No. 3 remains in the on state.

[0034] Electromagnetic power main switch No. 1 III-5 and electromagnetic power main switch No. 2 III-6 are controlled by power manager III-10 and power control switch III-3 at the same time. When power control switch III-3 is turned on and power manager III-10 outputs a low level, electromagnetic power main switches No. 1 and No. 2 will be turned on. When any one of the conditions is not met, electromagnetic power main switches No. 1 and No. 2 will be disconnected. Power control switch III-3 is manually controlled on and off, and power manager III-10 comprehensively judges whether to turn on the electromagnetic power main switch based on the voltage signal sent by IBS battery power sensor III-1 and the ambient temperature and speed signal sent by EECU engine controller III-13. Before the set power cut-off condition is reached, the power can be manually cut off through the power control switch III-3 to reduce the power consumption under this working condition.

[0035] In some embodiments, the power supply to different types of electrical equipment is started or disconnected according to the preset rules. Figure 5 ,include: S501, obtaining ambient temperature and engine speed; S502, determining a first rule according to the magnitude relationship between the ambient temperature and the preset temperature; S503, determining a second rule according to the magnitude relationship between the engine speed and the preset speed; S504, and determining a third rule according to the magnitude relationship between the real-time voltage of the battery and the preset voltage; S505: According to the first rule, the second rule and the third rule, start or disconnect the power supply to the different categories of electrical equipment.

[0036] In this embodiment, ambient temperature and engine speed parameters are introduced, and a series of rules and strategies are set to optimize the power management of commercial vehicles. For example, when the ambient temperature is lower than A, for example, when the engine speed is detected to be > B (i.e., the engine is running normally, this value can be calibrated), the household electrical appliances can be powered, otherwise the household electrical appliances are always in a power-off state. When the battery voltage is lower than C, for example, when the engine speed is detected to be > B (i.e., the engine is running normally, this value can be calibrated), all devices can be powered.

[0037] Furthermore, the first rule is that the ambient temperature is greater than a preset temperature; The second rule is that the engine speed is greater than a preset speed; The third rule is that the real-time voltage of the battery is greater than the preset voltage; When the second rule is met, all electrical equipment of different levels are classified and supplied with power; 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; When the third rule is not satisfied, all electrical equipment of different levels are classified and powered off.

[0038] Based on the judgment logic of the above different rules, it should be noted that the preset speed is the speed representing the normal operation of the engine. The preset temperature includes a first preset temperature and a second preset temperature, wherein when the second rule is not satisfied, the power supply on / off status of the household electrical equipment and / or the controlled electrical equipment is determined according to the relationship between the ambient temperature and the temperature threshold, and when the speed is lower than the preset speed (i.e., when the engine state is in an abnormal operating state), the controlled electrical equipment and the household electrical equipment are disconnected at the same time according to the first preset temperature and the second preset temperature of different temperature levels, or only the household electrical equipment is disconnected.

[0039] Furthermore, the preset voltage includes multiple voltage levels. Under different voltage levels, the power supply start and stop conditions of the normal power equipment, the controlled power equipment and the life 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: 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 main switches can output a low level; When the engine speed is 0 and the ambient temperature is <-25℃ (this value can be calibrated) and lasts for 1 minute, the pin connected to the No. 1 electromagnetic power main switch of the power manager III-10 cannot output a low level, and the power of household electrical appliances is cut off.

[0040] When the engine speed is 0 and the ambient temperature is <-40℃ (this value can be calibrated) and lasts for 1 minute, the pins connected to the No. 1 and No. 2 electromagnetic power main switches of the power manager III-10 cannot output a low level, and the power of household electrical appliances and controlled electrical equipment is cut off.

[0041] When the power manager III-10 detects that the battery voltage is ≥X1V and lasts for 1 minute, the pins connected to the three electromagnetic power switches of the power manager III-10 can output low level; When the power manager III-10 detects that the battery voltage is ≥X2V and lasts for 1 minute, the pins connected to the No. 2 and No. 3 electromagnetic power main switches of the power manager III-10 can output low level; When the power manager III-10 detects that the battery voltage is ≥X3V and lasts for 1 minute, the pins connected to the No. 3 electromagnetic power main switch of the power manager III-10 can output a low level; When the power manager III-10 detects that the battery voltage is <X3V and 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 being unable to start due to the battery being discharged.

[0042] When the above conditions are met, perform the on or off action. Otherwise, perform the reverse action. In this description, X1>X2>X3 (these values can be calibrated).

[0043] In some embodiments, obtaining the number of passive power-off times for each electrical equipment classification and determining the corresponding power protection mechanism according to the number of passive power-off times includes: Determine the protection mechanism for each electrical equipment classification under different numbers of passive power-off times according to the impact degree of the number of passive power-off times of the electrical equipment classification on vehicle operation and battery management; Determine the control strategy according to the protection mechanism for each electrical equipment classification under different numbers of passive power-off times.

[0044] In this embodiment, the power manager collects and records the number of passive power-off times of each type of electrical equipment. After sending the relevant data to the T-BOX, the T-BOX uploads it to the cloud. When the number of passive power-off times of the equipment reaches the regulated value, the power manager performs corresponding actions. And push the relevant information and commands to the driver in the form of messages through the mobile APP.

[0045] In a specific embodiment, as Figure 4 shown, the power manager is connected to the T-BOX through the CAN bus. The power manager monitors and records the number of times each electrical equipment is forced to power off (actively cut off by the power manager due to the trigger voltage being less than X), and sends the relevant data to the T-BOX through the CAN bus. The T-BOX uploads it to the cloud. The power manager triggers the power protection mechanism based on the number of times each electrical equipment is cut off within a period of time.

[0046] Furthermore, as Figure 4As shown, before each electrical device is automatically powered off, the power manager III-10 will issue an alarm and text prompt through the bus. The voice alarm can be played through the right turn prompt sound III-11, and the buzzer alarm and text prompt can be broadcast through the instrument III-12 to remind the driver to start the engine or connect the external power supply in time. In order to avoid power failure without warning, the alarm function should last for about 2 minutes (this value can be calibrated). When the power manager turns off all power supplies in certain specific circumstances, the power supply of the starting circuit is also cut off. In order not to affect the driver's normal engine start, a power reset switch III-14 can be set. When the driver presses the power reset switch III-14, the power manager III-10 forces the restoration of power supply to the No. 2 and No. 3 electromagnetic power main switches and lasts for 5 minutes (this value can be calibrated) to ensure that the driver has enough time to start the engine.

[0047] In a specific embodiment, the specific logic of the power protection mechanism is shown in Table 1: Table 1: Power protection mechanism trigger logic table

[0048] 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.

[0049] Based on the above commercial vehicle power management method, the present invention also provides a commercial vehicle power management device, see Figure 6 ,include: The classification module 610 is used to classify the electrical equipment of the vehicle according to the electrical properties and the degree of urgency of the electrical use of the equipment, and obtain a plurality of different levels of electrical equipment classification; The power supply and power-off module 620 is used to control the power supply and power-off of each power-consuming device classification according to preset rules; The protection module 630 is used to obtain the number of passive power-offs of each power-consuming device category and determine a corresponding power protection mechanism according to the number of passive power-offs.

Further, the memory 720 may also include both an internal storage unit of the electronic device and an external storage electronic device. The memory 720 is used to store application software and various types of data installed in the electronic device, such as program codes installed in the electronic device.
