Description

Technical Field

[0001] This application relates to the field of vehicle power management technology, and in particular to a vehicle power management method, system, device and medium for commercial vehicles. Background Technology

[0002] With the development of electronics and intelligence in commercial vehicles, the number of vehicle controllers is also increasing. There are cases where users use vehicle electrical appliances improperly when the vehicle is stationary and the engine is not running, which leads to the vehicle battery being depleted and affects the vehicle's starting.

[0003] Traditional methods to avoid non-standard use of vehicle electrical appliances include: (1) reminding users of the standard operating procedures in the user manual to ensure that after the vehicle is parked and turned off, the user effectively shuts off the vehicle power supply or keeps it on for a short period of time according to the vehicle's usage. (2) using the wake-up method of the PEPS (Passive Entry Passive Start) controller, for example, the vehicle remote control method, the vehicle and the readable storage medium (CN202010524123.0) receive control commands and authentication information sent by the external terminal through the TBOX control system; the TBOX control system sends the authentication information to the PEPS controller through the vehicle CAN network, and the TBOX control system and the PEPS controller verify the authentication information respectively; if both the TBOX control system and the PEPS controller pass the verification, the PEPS controller controls the vehicle according to the control command.

[0004] However, in practical applications, users may forget to turn off the main power switch when parking for extended periods, causing the vehicle to remain in a state of high static power consumption for a prolonged time. Furthermore, after turning off the main power switch, some operations are unavailable when the vehicle is stationary, requiring a power cycle to perform these operations, resulting in a poor user experience. Additionally, the PEPS controller primarily uses a TBOX for wake-up, making the PEPS wake-up strategy rather simplistic. Summary of the Invention

[0005] To address the aforementioned shortcomings of the existing technology, this application provides a vehicle power management method, system, device, and medium for commercial vehicles, in order to solve the problem that some operations cannot be performed when the vehicle is stationary and require a power cycle to perform the relevant operations; in addition, the PEPS controller has a single wake-up strategy.

[0006] In a first aspect, this application provides a vehicle power management method for commercial vehicles, the method comprising: acquiring the current power status of the vehicle power supply when a preset action command is triggered; acquiring the status of the PEPS ECU in the vehicle PEPS controller when the power status is OFF; determining a wake-up procedure to be executed based on the status of the PEPS ECU to wake up the PEPS ECU; controlling the electromagnetic power switch to remain closed after waking up the PEPS ECU; and sending a disconnect request to the PEPS controller through the body control module (BCM) if no power-on command is received within a preset waiting time, so that the PEPS controller disconnects the electromagnetic power switch upon receiving the request.

[0007] Furthermore, triggering preset action commands specifically includes: obtaining a remote control command from the remote key or sensing the vehicle door handle switch to complete the door opening action, or triggering the position light or triggering the hazard warning light.

[0008] Furthermore, the PEPS ECU's state includes a dormant state and a non-dormant state. Based on the PEPS ECU's state, a wake-up procedure is determined to wake up the PEPS ECU. Specifically, when the PEPS ECU is in a dormant state, an activation request is sent to the electromagnetic power switch via the Body Control Module (BCM) to control the electromagnetic power switch to engage, thereby waking up the PEPS ECU. When the PEPS ECU is in a non-dormant state, an activation request is sent to the electromagnetic power switch via the BCM to control the electromagnetic power switch to remain engaged, thereby continuously waking up the PEPS ECU.

[0009] Furthermore, after the PEPS controller disconnects the electromagnetic power main switch upon receiving a request, the method also includes: determining whether the PEPS controller should go into sleep mode based on the network status of the entire vehicle.

[0010] Secondly, this application provides a vehicle power management system for commercial vehicles. The system includes: an acquisition unit, used to acquire the current power status of the vehicle power supply when a preset action command is triggered; a control unit, used to acquire the status of the PEPS ECU in the vehicle PEPS controller when the power status is OFF; based on the status of the PEPS ECU, determine the wake-up procedure to be executed to wake up the PEPS ECU; after waking up the PEPS ECU, control the electromagnetic power switch to remain closed; and a disconnection unit, used to send a disconnection request to the PEPS controller through the body control module (BCM) if the body control module (BCM) does not receive a power-on command within a preset waiting time, so that the PEPS controller disconnects the electromagnetic power switch upon receiving the request.

[0011] Furthermore, the acquisition unit includes an acquisition subunit, used to acquire the remote control command of the remote key or sense the vehicle door handle switch to complete the door opening action or trigger the position light or trigger the hazard alarm light.

[0012] Furthermore, the control unit includes a wake-up subunit, which is used to send an activation request to the electromagnetic power switch via the body control module (BCM) when the PEPS ECU is in a dormant state, so as to control the electromagnetic power switch to be engaged and thus wake up the PEPS ECU; when the PEPS ECU is not in a dormant state, it sends an activation request to the electromagnetic power switch via the body control module (BCM) to control the electromagnetic power switch to remain engaged, so as to continuously wake up the PEPS ECU.

[0013] Furthermore, the system also includes a controller control unit: used to determine whether the PEPS controller should go into sleep mode based on the network status of the entire vehicle.

[0014] Thirdly, this application provides a vehicle power management device for commercial vehicles, the device including: a processor; and a memory storing executable code thereon, which, when executed, causes the processor to execute a vehicle power management method for commercial vehicles as described above.

[0015] Fourthly, this application provides a non-volatile computer storage medium storing computer instructions thereon, which, when executed, implement a vehicle power management method for commercial vehicles as described above.

[0016] Those skilled in the art will understand that this application has at least the following beneficial effects: The vehicle's power on / off functionality is automated, requiring no external operation. Users trigger preset action commands, which are completed from inside the driver's cab, preventing repeated power cycles and potential misuse of the in-vehicle controller. Preset action commands include activating position lights and hazard warning lights, ensuring PEPS (Power Equipped Surround Control System) is activated and powered continuously even when the vehicle is powered off. To leave the cab, the PEPS controller can be activated in the OFF state, allowing commands to be sent to lock the doors. Conversely, when the doors are locked in the OFF state, commands can be sent via the PEPS controller to unlock them. Attached Figure Description

[0020] Those skilled in the art should understand that the embodiments described below are merely preferred embodiments of this disclosure and do not imply that this disclosure can only be implemented through these preferred embodiments. These preferred embodiments are merely used to explain the technical principles of this disclosure and are not intended to limit the scope of protection of this disclosure. Based on the preferred embodiments provided by this disclosure, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of this disclosure.

[0021] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0022] The technical solutions proposed in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] This application provides a vehicle power management method for commercial vehicles, such as... Figure 1 As shown in the embodiments of this application, the method mainly includes the following steps: Step 110: When the preset action command is triggered, obtain the current power status of the vehicle's power supply.

[0024] It should be noted that triggering preset action commands can be a remote control command obtained from the remote key, a door opening action completed by sensing the vehicle door handle switch, or the activation of the position light or hazard warning light. Power states include OFF, ACC, IGNON (Engine on / off), and Cranking, which are common knowledge in the art and will not be elaborated upon here.

[0025] Step 120: When the power supply is in the OFF state, obtain the status of the PEPS ECU in the vehicle PEPS controller; based on the status of the PEPS ECU, determine the wake-up procedure to be executed to wake up the PEPS ECU; after waking up the PEPS ECU, control the electromagnetic power switch to remain continuously engaged.

[0026] It should be noted that the PEPS ECU (Electronic Control Unit) is an electronic control unit and the core component of the PEPS controller. This is common knowledge in the field and will not be elaborated upon here. The PEPS ECU has two states: a dormant state and a non-dormant state.

[0027] Specifically, based on the state of the PEPS ECU, the wake-up procedure to be executed is determined to wake up the PEPS ECU, which can be as follows: When the PEPS ECU is in a dormant state, an activation request is sent to the electromagnetic power switch via the Body Control Module (BCM) to activate the electromagnetic power switch and wake up the PEPS ECU. When the PEPS ECU is not in a dormant state, an activation request is sent to the electromagnetic power switch via the BCM to keep the electromagnetic power switch activated and continuously wake up the PEPS ECU.

[0028] Step 130: If the Body Control Module (BCM) does not receive a power-on command within the preset waiting time, the BCM sends a disconnection request to the PEPS controller so that the PEPS controller disconnects the electromagnetic power main switch upon receiving the request.

[0029] After the PEPS controller receives a request and disconnects the electromagnetic main power switch, the method further includes determining whether the PEPS controller should go into sleep mode based on the network status of the vehicle.

[0030] It should be further explained that, specifically, when the key signal, hard-wired signal shutdown, or network wake-up signal cessation is detected, the PEPS controller requests the drive control unit (DCU) to exit operating mode and reduce power. Subsequently, the PEPS controller requests the DC / DC converter to exit operating mode and then requests the BMS to disconnect the high-voltage relay. After the BMS completes its response, the PEPS controller disconnects the high-voltage interlock circuit and the low-voltage relay, and each node enters the power-down sleep process. The BMS determines whether to enter sleep mode based on the bus current and voltage. If the bus current is less than a certain current, the main positive relay and the main negative relay are disconnected sequentially. When the voltage drops to a certain preset value, the BMS sends a power-down command to the PEPS controller and enters the power-down Afterrun state. Finally, after the BMS sends the power-down completion command, it enters sleep mode after a period of time.

[0031] besides, Figure 2 This application provides a vehicle power management system for commercial vehicles. For example... Figure 2As shown in the embodiments of this application, the system mainly includes: The acquisition unit 210 is used to acquire the current power status of the vehicle power supply when a preset action command is triggered.

[0032] The acquisition unit 210 includes an acquisition subunit, which is used to acquire the remote control command of the remote key or sense the door handle switch of the vehicle to complete the door opening action or trigger the position light or trigger the hazard alarm light.

[0033] The control unit 220 is used to acquire the status of the PEPS ECU in the vehicle PEPS controller when the power supply is in the OFF state; determine the wake-up program to be executed based on the status of the PEPS ECU to wake up the PEPS ECU; and control the electromagnetic power switch to remain closed after waking up the PEPS ECU.

[0034] The control unit 220 includes a wake-up subunit, which is used to send an activation request to the electromagnetic power switch via the body control module (BCM) when the PEPS ECU is in a dormant state, so as to control the electromagnetic power switch to be engaged and thus wake up the PEPS ECU; and to send an activation request to the electromagnetic power switch via the body control module (BCM) when the PEPS ECU is not in a dormant state, so as to control the electromagnetic power switch to remain engaged and continuously wake up the PEPS ECU.

[0035] The disconnection unit 230 is used to send a disconnection request to the PEPS controller through the body control module BCM after the body control module BCM does not receive a power-on command within a preset waiting time, so that the PEPS controller disconnects the electromagnetic power main switch upon receiving the request.

[0036] The system also includes a controller control unit: used to determine whether the PEPS controller should go into sleep mode based on the network status of the entire vehicle.

[0037] The above are method embodiments of this application. Based on the same inventive concept, this application also provides a vehicle power management device applied to commercial vehicles. Figure 3 As shown, the device includes: a processor; and a memory storing executable code thereon, which, when executed, causes the processor to perform a vehicle power management method for commercial vehicles as described in the above embodiments.

[0038] Specifically, when the server triggers a preset action command, it obtains the current power status of the vehicle's power supply; when the power status is OFF, it obtains the status of the PEPS ECU in the vehicle's PEPS controller; based on the status of the PEPS ECU, it determines the wake-up procedure to be executed to wake up the PEPS ECU; after waking up the PEPS ECU, it controls the electromagnetic power switch to remain closed; if the body control module (BCM) does not receive a power-on command within a preset waiting time, it sends a disconnection request to the PEPS controller through the body control module (BCM), so that the PEPS controller disconnects the electromagnetic power switch upon receiving the request.

[0039] In addition, embodiments of this application also provide a non-volatile computer storage medium storing executable instructions, which, when executed, implement the vehicle power management method for commercial vehicles as described above.
