[0002] With the rapid development of electronic intelligent technology in commercial vehicles, the number of electronic components integrated in vehicles is increasing, which not only improves the functionality and intelligence level of vehicles, but also puts forward more stringent requirements on the vehicle power management system. The on-board battery, as the core component of vehicle starting, is directly related to whether the vehicle can start smoothly.

[0003] However, when the battery is idle for a long time, it will discharge naturally. In addition, some users may use the vehicle electrical appliances improperly when the engine is not started, which will accelerate the consumption of the battery power. In serious cases, the battery power may be exhausted, thus affecting the vehicle's starting ability. In the prior art, the user manual is mainly used to guide users to standardize operations, and users are advised to start the vehicle regularly to charge the battery to ensure that the vehicle can start normally.

[0004] However, when the user is on a business trip or the vehicle is not used frequently, the user may forget to start the vehicle regularly to charge the battery, which causes the battery to be exhausted and ultimately causes the vehicle to fail to start normally. Summary of the invention

[0073] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0074] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0075] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0076] In the prior art, a user manual is needed to guide users in standardized operations, and users are advised to start the vehicle regularly to charge the battery. However, when traveling or using the vehicle infrequently, users may forget to start the vehicle regularly to charge the battery, resulting in battery depletion and ultimately the inability to start the vehicle normally.

[0077] Based on this, the inventive concept of this application is to provide a vehicle power management method, which does not require the user to start the vehicle regularly to charge the battery. Instead, the user can remotely start the vehicle to charge the battery by reminding the user that the battery needs to be charged. Based on this, the power monitoring module is set to continuously detect the battery power, and then when the battery power is too low, a message is sent to the user terminal to remind the user that the vehicle needs to be started to charge the battery. When the user agrees to charge the battery at the user terminal, the PEPS controller control will automatically control the vehicle's engine to start to charge the battery. Therefore, the user does not need to start the vehicle regularly to charge the battery, which results in the battery being exhausted due to forgetting to start the vehicle regularly when the vehicle is not used frequently, and the vehicle cannot be started normally.

[0078] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0079] Figure 1 Schematic diagram of an application scenario of the vehicle power management method applicable to the embodiment of the present application, such as Figure 1 As shown, the power monitoring module is responsible for continuously monitoring the battery power, and when the battery power is less than or equal to the first power threshold and greater than or equal to the second power threshold, the PEPS controller is awakened and a message is sent to the PEPS controller indicating that the vehicle needs to be started to charge the battery. After receiving the message, the PEPS controller will send it to the user terminal via the central gateway controller, TBOX, and cloud server for the user to view. After the user receives the message that the vehicle needs to be started to charge the battery, the user will enter a charging instruction in the user terminal, and then the charging instruction will be sent to the PEPS controller via the cloud server, TBOX, and central gateway controller in sequence. After receiving the charging instruction, the PEPS controller will control the vehicle transmitter to start to charge the battery.

[0080] Figure 2 A flow chart of a vehicle power management method embodiment 1 provided in this application, such as Figure 2 As shown, the method comprises the following steps:

[0081] S201: The power monitoring module detects the pre-charging power of the battery on the vehicle, and when the pre-charging power is less than or equal to a first power threshold and greater than or equal to a second power threshold, wakes up the PEPS controller to send a first message to the PEPS controller, the first message is used to request an intelligent start of the vehicle to charge the battery, and the second power threshold is less than the first power threshold.

[0082] In an embodiment of the present application, the vehicle power management method is applied to the vehicle power management system, which includes: a power monitoring module, a keyless system PEPS controller, a central gateway controller, a car black box TBOX, a cloud server and a user terminal.

[0083] Among them, the power monitoring module is responsible for continuously or periodically detecting the pre-charge power of the battery on the vehicle, and the pre-charge power refers to the remaining power of the battery before starting the vehicle for charging. When the power monitoring module detects that the pre-charge power of the battery is less than or equal to the first power threshold, and greater than or equal to the second power threshold, optionally, the first power threshold is 30% of the battery capacity, and the second power threshold is 10% of the battery capacity, the power monitoring module wakes up the PEPS controller through the local interconnect network bus LIN line, and sends a first message to the PEPS controller through the local interconnect network bus LIN line, for requesting an intelligent start of the vehicle to charge the battery.

[0084] For example, the power monitoring module sends a specific wake-up frame through the local interconnect network bus LIN line to wake up the PEPS controller. After receiving the wake-up frame, the PEPS controller exits the sleep mode and enters the working state. Then the power monitoring module constructs a message frame containing a first message according to the specification of the LIN protocol. When the PEPS controller receives the message frame containing the first message, it parses it and then requests to intelligently start the vehicle according to the first message to charge the battery.

[0085] S202: The PEPS controller sends the first message to the user terminal via the central gateway controller, TBOX, and cloud server in sequence.

[0086] In the embodiment of the present application, after receiving the first message, the PEPS controller sends it to the user terminal via the central gateway controller, TBOX, and cloud server in sequence. Specifically, when the PEPS controller sends the first message to the user terminal, the PEPS controller first sends it to the central gateway controller via the local area network CAN line, and the central gateway controller then sends it to the TBOX via the local area network CAN line. After receiving the first message, the TBOX will send it to the cloud server, which is the central node for the vehicle to exchange and store data with the outside world. After receiving the first message, the cloud server will forward the first message to the user terminal by SMS, email, or APP push, etc., to inform the user of the status of the vehicle battery. Optionally, the TBOX communicates with the cloud server using a cellular network or other wireless communication technology, and the cloud server can also communicate with the user terminal using a cellular network or other wireless communication technology. Among them, the PEPS controller and the central gateway controller, as well as the central gateway controller and the TBOX, transmit information through the CAN line after mutual authentication.

[0087] S203: When the PEPS controller receives a charging instruction sent by the user terminal via the cloud server, TBOX, and the central gateway controller in sequence, it unlocks the electronic steering column lock of the vehicle.

[0088] In an embodiment of the present application, after the user terminal receives the first message sent by the PEPS controller, the user terminal can send a charging instruction to the PEPS controller. After receiving the charging instruction, the PEPS controller will first verify the legality and validity of the instruction. If the verification passes, the PEPS controller will send an unlocking instruction to the electronic steering column lock (Electronic Steering Column Lock, ESCL). After receiving the unlocking instruction, the electronic steering column lock will perform an unlocking operation to allow the steering wheel to be turned, thereby starting the engine.

[0089] Among them, the path for the user terminal to send the charging instruction to the PEPS controller is: the user terminal sends the charging instruction to the cloud server via the cellular network or other wireless communication technologies. After the cloud server receives the charging instruction, it also sends it to the TBOX via the cellular network or other wireless communication technologies. When the TBOX receives the charging instruction, it sends the charging instruction to the central gateway controller via the local area network CAN line. When the central gateway controller receives the charging instruction, it sends the charging instruction to the PEPS controller via the local area network CAN line.

[0090] When the power monitoring module does not receive the charging instruction, the power monitoring module returns to the step of detecting the pre-charging power of the battery on the vehicle.

[0091] In an embodiment of the present application, when the power monitoring module does not receive the charging instruction in the first message, the power monitoring module returns to step S201, that is, the power monitoring module continues to perform its function of detecting the pre-charging power of the battery on the vehicle, ensuring the continuous operation of the vehicle power management system and real-time monitoring of the battery power, providing users with a more reliable and safe vehicle use experience.

[0092] S204: When the electronic steering column lock is unlocked successfully, the PEPS controller controls the vehicle's engine to start to charge the battery.

[0093] In the embodiment of the present application, when the electronic steering column lock is unlocked successfully, (check whether other conditions are met: whether the vehicle is in a safe state, the PEPS controller controls the engine of the vehicle to start to charge the battery.

[0094] When the electronic steering column lock fails to unlock, it also includes:

[0095] When the electronic steering column lock fails to be unlocked, the PEPS controller sends a third message to the user terminal via the central gateway controller, TBOX, and cloud server in sequence, and controls the electronic steering column lock to be locked. The third message is used to indicate that the reason for the charging failure is the failure to unlock the electronic steering column lock.

[0096] In an embodiment of the present application, when the electronic steering column lock fails to be unlocked, the PEPS controller sends a third message to the user terminal to prompt the user that charging has failed, so that the user can manually start the vehicle for charging, and the PEPS controller will control the electronic steering column lock to remain locked to prevent the vehicle from being stolen or misoperated, and ensure the safety of the vehicle and personnel. Among them, the third message is used to indicate to the user that the reason for the charging failure is the failure to unlock the electronic steering column lock. The path for the PEPS controller to send the third message to the user terminal is: the third message is sent to the user terminal via the central gateway controller, TBOX, and cloud server in sequence.

[0097] In an embodiment of the present application, the power monitoring module detects the pre-charging power of the battery on the vehicle, and when the pre-charging power is less than or equal to the first power threshold and greater than or equal to the second power threshold, wakes up the PEPS controller to send a first message to the PEPS controller, the first message is used to request an intelligent start of the vehicle to charge the battery, the second power threshold is less than the first power threshold, the PEPS controller sends the first message to the user terminal via the central gateway controller, TBOX, and the cloud server in sequence, and then the PEPS controller unlocks the electronic steering column lock of the vehicle when receiving the charging instruction sent by the user terminal via the cloud server, TBOX, and the central gateway controller in sequence, and finally when the electronic steering column lock is unlocked successfully, the PEPS controller controls the vehicle's engine to start to charge the battery. Compared with the prior art, which requires users to start the vehicle regularly to charge the battery, the power monitoring module of the present application continuously detects the power level of the battery on the vehicle, and when the battery power is less than or equal to a first power threshold and greater than or equal to a second power threshold, sends information to the user terminal to remind the user that the vehicle needs to be charged. When the user receives the instruction to charge, the user will send a charging instruction to the PEPS controller, so that the PEPS controller controls the vehicle's engine to start to charge the battery. This makes it unnecessary for the user to go to the vehicle to start the vehicle regularly to charge the battery. Instead, the user can actively detect the battery power and then actively remind the user that the battery needs to be charged. After obtaining the user's permission, the vehicle can be remotely started to charge the battery.

[0098] Figure 3 This is a flow chart of a second embodiment of a vehicle power management method provided by this application. Figure 2 Based on the illustrated embodiment, a specific implementation of step S204 is as follows:

[0099] S301: During the charging process, the power monitoring module continuously monitors the charging progress and sends the charging progress to the PEPS controller. The charging progress includes at least one of the following information: charging time and charging power.

[0100] In an embodiment of the present application, when the engine is charging the battery, the power monitoring module continuously monitors the charging progress, which is the charging time and / or the amount of electricity being charged. The power monitoring module also sends the charging time and / or the amount of electricity being charged to the PEPS controller via the local interconnect network bus LIN line.

[0101] S302: When the charging progress meets the preset conditions, the PEPS controller controls the engine to continue running, and the preset conditions include at least one of the following conditions: the charging time is less than or equal to the preset time threshold, the charging power is less than or equal to the third power threshold, and the third power threshold is greater than the first power threshold.

[0102] In an embodiment of the present application, when the charging progress meets the preset conditions, the PEPS controller controls the engine to continue running to complete the charging process. Optionally, the preset conditions are: the charging time is less than or equal to the preset time threshold, and the charging power is less than or equal to the third power threshold, where the third power threshold is greater than the first power threshold. In other words, the charging time can be set to ensure that the charging is completed, or the charging power can be monitored to ensure that the charging is completed. The preset charging time threshold can be determined based on the average of the general charging time, and the third power threshold is greater than 30% of the battery capacity. Optionally, the third power threshold is 100% or 90% of the battery power.

[0103] S303: When the charging progress does not meet the preset conditions, the PEPS controller controls the engine to stop running.

[0104] In an embodiment of the present application, when the charging progress does not meet the preset conditions, that is, the charging time is greater than the preset time threshold, and / or the charging power is greater than the third power threshold, the PEPS controller controls the engine to stop running to cut off charging of the battery.

[0105] When the charging progress does not meet the preset conditions and the PEPS controller controls the engine to stop running, the following steps are also included:

[0106] When the engine is stopped, the PEPS controller controls the electronic steering column lock to be locked and switches the main switch of the battery to the off state. When the main switch of the battery is in the off state, the battery stops supplying power to the vehicle's electrical equipment.

[0107] In the embodiment of the present application, when the engine stops running and the battery is no longer charged, the PEPS controller will control the electronic steering column lock to lock to prevent the vehicle from being stolen or misoperated after the engine stops. Then the PEPS controller will switch the battery's main switch KL30 electromagnetic power main switch to the off state. At this time, the battery will stop supplying power to the vehicle's electrical equipment to prevent the battery from continuing to discharge when the engine is not running, ensuring that the battery is fully charged, thereby extending the battery's service life.

[0108] Optionally, the PEPS controller can also control the switching of the ACC relay, IGN1 relay, and IGN2 relay. For example, during ignition, due to the large power consumption during ignition, the PEPS controller controls the ACC relay and IGN1 relay to be closed to stop supplying power to devices such as large screens, and only turns on the IGN2 relay to only supply power to the ignition device.

[0109] In the embodiment of the present application, during the charging process, the power monitoring module continuously monitors the charging progress and sends the charging progress to the PEPS controller. The charging progress includes at least one of the following information: charging time, charging power. When the charging progress meets the preset conditions, the PEPS controller controls the engine to continue running. The preset conditions include at least one of the following conditions: the charging time is less than or equal to the preset time threshold, the charging power is less than or equal to the third power threshold, and the third power threshold is greater than the first power threshold. When the charging progress does not meet the preset conditions, the PEPS controller controls the engine to stop running. During the charging process, the power monitoring module continuously monitors the charging progress to ensure that the battery can reach the target state when charging, and when the target state is reached, the PEPS controller controls the engine to stop running, so as to save energy and avoid damage to the battery caused by overcharging, thereby ensuring the efficiency and safety of the battery charging process.

[0110] Figure 4 This is a flow chart of a third embodiment of a vehicle power management method provided by this application. Figure 3 Based on the illustrated embodiment, a specific implementation of step S303 is as follows:

[0111] S401: The PEPS controller sends a second message to the user terminal via the central gateway controller, TBOX, and cloud server in sequence. The second message is used to request whether to end charging, and the second message includes the charging progress.

[0112] In the embodiment of the present application, during the charging process, the power monitoring module continuously monitors the charging progress, and after sending the charging progress to the PEPS controller, the PEPS controller can send the charging progress to the user terminal through the central gateway controller, TBOX, and the cloud server. Specifically, when the PEPS controller receives the charging progress sent by the power monitoring module, the PEPS controller sends it to the central gateway controller via the local area network CAN line, and the central gateway controller sends it to the TBOX via the local area network CAN line. After receiving the charging progress, the TBOX will send it to the cloud server. After receiving the charging progress, the cloud server will forward the charging progress to the user terminal to inform the user of the charging progress of the vehicle.

[0113] Optionally, the PEPS controller may periodically send a second message to the user terminal to remind the user whether the battery charging process needs to be terminated.

[0114] S402: When the user terminal receives the charging control instruction input by the user, it sends the charging control information to the PEPS controller via the cloud server, TBOX, and central gateway controller in sequence.

[0115] In the embodiment of the present application, after the user terminal receives the charging progress, it will display the current charging progress to the user and wait for the user to input the charging control instruction. The charging control instruction is used to indicate the charging control information according to the user's needs. The charging control information will be sent to the PEPS controller via the cloud server, TBOX, and the central gateway controller. Specifically, after the user terminal generates the charging control information according to the charging control instruction input by the user, the user terminal sends the charging control information to the cloud server via the cellular network or other wireless communication technology. After the cloud server receives the charging control information, it also sends it to the TBOX via the cellular network or other wireless communication technology. When the TBOX receives the charging control information, it sends the charging control information to the central gateway controller via the local area network CAN line. When the central gateway controller receives the charging control information, it sends the charging instruction to the PEPS controller via the local area network CAN line.

[0116] S403: When the charging control information is charging end information, the engine is controlled to stop running.

[0117] In the embodiment of the present application, when the charging control information is charging end information, the PEPS controller will control the engine to stop running to end charging the battery.

[0118] S404: When the charging control information is charging continuation information, the engine is controlled to continue running until the charging power of the vehicle is fully charged, and then the engine is controlled to stop running.

[0119] In the embodiment of the present application, when the charging control information is the charging continuation information, the PEPS controller will control the engine to continue running until the charging power of the vehicle is fully charged, and then the PEPS controller will control the engine to stop running to end the charging of the battery.

[0120] In the embodiment of the present application, the PEPS controller sends a second message to the user terminal via the central gateway controller, TBOX, and cloud server in sequence. The second message is used to request whether to end charging. The second message includes the charging progress. When the user terminal receives the charging control instruction input by the user, it sends the charging control information to the PEPS controller via the cloud server, TBOX, and central gateway controller in sequence. When the charging control information is the charging end information, the engine is controlled to stop running. When the charging control information is the charging continuation information, the engine is controlled to continue running until the vehicle is fully charged. The engine is controlled to stop running. By sending the charging progress to the user terminal, the user can flexibly decide whether to end charging according to his own time and power requirements, thereby improving the convenience of charging. In addition, the user can reasonably plan the charging time according to the charging progress, choose to charge in a time period with lower electricity charges, reduce the charging cost, and also reduce the load pressure of the power grid.

[0121] Figure 5 A schematic diagram of a vehicle power management method embodiment 4 provided in this application, such as Figure 5 As shown, the method comprises the following steps:

[0122] S501: When the power level before charging is less than or equal to the second power threshold, the power monitoring module wakes up the PEPS controller to send a fourth message to the PEPS controller. The second power threshold is less than the first power threshold. The fourth message is used to indicate that the battery power is insufficient to start the vehicle intelligently.

[0123] In an embodiment of the present application, when the power monitoring module detects that the power level before charging is less than or equal to the second power threshold, that is, the power level before charging is less than or equal to 10% of the battery power, the power monitoring module will wake up the PEPS controller. After the PEPS controller is awakened, it will send a response to the power monitoring module to indicate that the PEPS controller is ready to receive messages. The power monitoring module then sends a fourth message to the PEPS controller to indicate that the battery power is insufficient to intelligently start the vehicle.

[0124] S502: The PEPS controller sends the fourth message to the user terminal via the central gateway controller, TBOX, and cloud server in sequence, and adjusts the battery status to the off status.

[0125] In the embodiment of the present application, after receiving the fourth message, PEPS will send the fourth message to the user terminal via the central gateway controller, TBOX, and cloud server in sequence, and the PEPS controller will adjust the battery status to the off state, that is, cut off the KL30 electromagnetic power main switch of the battery to reduce unnecessary power consumption, and then wait for the user to go to the vehicle and start the vehicle with the physical key.

[0126] In the embodiment of the present application, when the power before charging is less than or equal to the second power threshold, the power monitoring module wakes up the PEPS controller to send a fourth message to the PEPS controller, the second power threshold is less than the first power threshold, and the fourth message is used to indicate that the battery power is insufficient to start the vehicle intelligently. Then the PEPS controller sends the fourth message to the user terminal via the central gateway controller, TBOX, and cloud server in sequence, and adjusts the battery state to the off state, which can avoid battery damage or vehicle failure to start due to power exhaustion. By sending a notification to the user terminal when the battery power drops to a lower level but is not exhausted, when the vehicle cannot be intelligently started, the user goes to the location of the vehicle and uses the physical key to start the vehicle, avoiding the embarrassing situation that the user is in trouble because the vehicle cannot start when the battery power is exhausted.

[0127] Figure 6 A schematic diagram of a vehicle power management method embodiment 5 provided in this application, such as Figure 6 As shown, the method comprises the following steps:

[0128] S601: The user terminal receives setting information input by the user, and the setting information includes at least one of the following information: a first control parameter of the power monitoring module, or a second control parameter of the PEPS controller, the first control parameter includes at least one of the following: a first power threshold, a second power threshold, and the second control parameter includes at least one of the following: a preset duration threshold, a third power threshold, and one or more information templates, where the information template is used to indicate the format of any information in the first message, the second message, the third message, or the fourth message.

[0129] In an embodiment of the present application, a user can input setting information through a user terminal, and the setting information is used to adjust relevant parameters of the vehicle power management system. The setting information includes: a first control parameter of the power monitoring module and / or a second control parameter of the PEPS controller. Among them, the first parameter includes: a first power threshold and / or a second power threshold, and the first power threshold and the second power threshold are used to trigger the alarm mechanism of the power monitoring module. The second parameter includes: a preset duration threshold, a third power threshold, one or more information templates, and the information template is used to determine the first message, the second message, the third message, or the fourth message format sent to the user.

[0130] S602: The user terminal sends the setting information to the PEPS controller via the cloud server, TBOX, and central gateway controller in sequence.

[0131] In an embodiment of the present application, the user terminal will send the setting information to the PEPS controller through the cloud server, TBOX, and central gateway controller, so that the PEPS controller adjusts the relevant parameters of the vehicle power management system according to the setting information.

[0132] S603: When the setting information includes the first control parameter, the PEPS controller forwards the first control parameter to the power monitoring module.

[0133] In an embodiment of the present application, when the PEPS controller receives the setting information input by the user terminal, it determines whether the setting information includes the first control parameter. If the setting information includes the first control parameter, the PEPS controller forwards the first control parameter to the power monitoring module so that the power monitoring module can trigger the alarm mechanism of the power monitoring module according to the first power threshold and the second power threshold in the first parameter.

[0134] In the embodiment of the present application, the user terminal receives the setting information input by the user, and the setting information includes at least one of the following information: the first control parameter of the power monitoring module, or the second control parameter of the PEPS controller, and then the user terminal sends the setting information to the PEPS controller through the cloud server, TBOX, and central gateway controller in sequence. When the setting information includes the first control parameter, the PEPS controller forwards the first control parameter to the power monitoring module. This allows the user to customize the relevant parameters of the power management system through the user terminal according to their own needs and preferences, so that it can adapt to the usage habits and vehicle usage scenarios of different users.
