[0042] In order to ensure the safety of the vehicle, the prior art combines the self-monitoring function of the electronic water pump and certain control strategies to ensure the normal operation of the electronic water pump. For example, the water pump is precisely controlled by a non-inductive FOC (Field-Oriented Control) algorithm.

However, the above-mentioned solutions focus on the vehicle starting operation, electronic water pump operation control and problem detection to ensure the performance and safety of the vehicle, and do not consider the technical problem that the electronic water pump cannot work due to the cooling circuit blockage when the vehicle is not used for a long time and the electronic water pump is in a long-term non-operation state.

[0043] In order to solve the above technical problems, the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0044] Embodiment one

[0045] Please refer to Figure 1 An automobile electronic water pump self-starting maintenance method provided by an embodiment of the present application includes S10 to S30, specifically:

[0046] S10: When the vehicle is in OFF mode, the vehicle controller module assembly is awakened by the vehicle-mounted TBOX.

[0047] Preferably, in some embodiments of the present application, OFF mode refers to the power supply or ignition switch of the vehicle being in the off state. For example, in an electric vehicle or hybrid vehicle, OFF mode usually indicates that the high-voltage battery system of the vehicle is turned off, and the electric motor no longer provides power. At this time, the main systems of the vehicle (such as the power system and air conditioning system) usually stop running, but some low-voltage electrical equipment may still be awakened and operated by an external signal (such as a vehicle-mounted TBOX).

[0048] Preferably, in some embodiments of the present application, the vehicle controller module assembly refers to an integrated system of electronic control units or control modules for controlling and managing various systems and functions of the vehicle, including but not limited to: Vehicle Control Unit (VCU), Hybrid Control Unit (HCU), and Power Control Unit (PCU).

[0049] Preferably, in some embodiments of the present application, the vehicle controller module assembly can be awakened by the vehicle TBOX, and a certain preset condition can be set in the TBOX, such as when the vehicle is in OFF gear, or in response to the user sending an instruction to the TBOX through external remote control (such as mobile phone application, remote server, etc.), thereby awakening the vehicle controller module assembly.

[0050] S20: monitoring the downtime of each electronic water pump by the vehicle controller module assembly.

[0051] Preferably, in some embodiments of the present application, the electronic water pump corresponds to a cooling circuit, including but not limited to a motor cooling circuit, a battery cooling circuit, and an engine cooling circuit. Each cooling circuit has a corresponding electronic water pump, and the vehicle controller module assembly needs to monitor all electronic water pumps corresponding to the cooling circuits in real time, and independently calculate the downtime of each electronic water pump, thereby ensuring the smoothness of each cooling circuit.

[0052] Preferably, in some embodiments of the present application, the vehicle controller module assembly maintains a start-stop time point record table for each electronic water pump to calculate the downtime of each electronic water pump.

[0053] S30: When the downtime of the electronic water pump is greater than the first threshold value, the vehicle controller module assembly controls the high voltage on the vehicle and starts the corresponding electronic water pump.

[0054] Further, in some embodiments of the present application, the vehicle controller module assembly controls the high voltage on the vehicle, including:

[0055] When the vehicle is in OFF gear, the battery management system is awakened by the vehicle TBOX;

[0056] The vehicle controller module assembly sends a closed high-voltage switch instruction to the battery management system, so that the battery management system closes the main positive relay and the main negative relay.

[0057] Preferably, in some embodiments of the present application, a battery management system (BMS) is used to manage and monitor the battery pack status and provide power source for the whole vehicle.

[0058] The vehicle-mounted TBOX wakes up the battery management system while waking up the whole vehicle controller module assembly, and controls the battery management system to close the main positive and negative relays through the whole vehicle controller module assembly, thereby providing stable power supply for the subsequent start of the electronic water pump, realizing more flexible maintenance and water pump start control, and improving system reliability.

[0059] Further, in some embodiments of the present application, the starting corresponds to the electronic water pump, comprising:

[0060] Waking up the electronic water pump through the whole vehicle controller module assembly;

[0061] Starting the electronic water pump according to a preset duty ratio through the whole vehicle controller module assembly.

[0062] The method of waking up the electronic water pump through the whole vehicle controller module assembly and starting according to a preset duty ratio can accurately control the water pump start process. In addition, controlling the speed of the electronic water pump through the preset duty ratio can effectively prevent overrunning, improve energy efficiency, and reduce the power consumption and wear of the water pump during start-up.

[0063] Preferably, in some embodiments of the present application, when it is monitored that any cooling loop corresponding electronic water pump has not started for a certain time, if there is other electronic water pump in the starting state at this time, causing the whole vehicle to be in the high pressure state, at this time, the battery management system is avoided from being repeatedly issued with the closing high voltage switch instruction, and the electronic water pump with the stop time longer than the first threshold value is directly started.

[0064] Further, in some embodiments of the present application, after starting the electronic water pump, further comprising:

[0065] When the first preset condition is met, stopping the electronic water pump through the whole vehicle controller module assembly;

[0066] The first preset condition includes that the electronic water pump has met the first preset time length of needing to run, and during the electronic water pump is in the starting state, the whole vehicle controller module assembly monitors other high pressure behaviors.

[0067] By setting the first preset condition to control the stopping behavior of the electronic water pump, when the preset running time is met or other high pressure behaviors are detected, the running state of the water pump is intelligently controlled, unnecessary running or inappropriate running is avoided to cause the whole vehicle state to be abnormal, not only reducing energy waste, but also realizing more intelligent maintenance control.

[0068] Preferably, in some embodiments of the present application, the first preset time length is preferably 1 minute.

[0069] Preferably, in some embodiments of the present application, when all the currently started electronic water pumps have met the first preset time length of required operation, the corresponding electronic water pump is stopped, at the same time, the high-voltage lowering instruction is sent to the BMS through the vehicle controller module assembly, the main positive and main negative relays are disconnected, and the shutdown time length of the electronic water pump of each cooling circuit is continued to be monitored.

[0070] Further, in some embodiments of the present application, the other high-voltage raising behaviors include: the vehicle entering a charging state, the user actively raising high voltage through an integrated brake control system, and the vehicle being in an ON gear.

[0071] When the vehicle enters a charging state or the user actively raises high voltage, the electronic water pump is stopped to avoid the redundant electronic water pump self-maintenance action causing the electronic water pump to wear out, thereby prolonging the service life of the electronic water pump. In addition, when the vehicle is in an ON gear, the resources of the high-voltage system are concentrated for driving and key systems by stopping the operation of the electronic water pump, thereby reducing the load of the high-voltage system, avoiding system problems caused by uneven power distribution during vehicle operation, and improving the safety of the vehicle.

[0072] Preferably, in some embodiments of the application, when the user actively raises high voltage, the Integrated Brake Control (IBC) sends a user remote high-voltage raising request signal or the vehicle key gear is in an ON gear. At this time, the vehicle controller module assembly does not need to send a high-voltage lowering instruction to the BMS, and only needs to control the electronic water pump to stop running through the PWM / LIN (Pulse Width Modulation / Local Interconnect Network) communication channel.

[0073] Further, in some embodiments of the present application, when the vehicle enters a charging state, it further includes:

[0074] The charging state includes a slow charging state and a fast charging state.

[0075] The slow charging state is determined by the vehicle controller module assembly receiving a first connection signal sent by the CDU of the vehicle, and the fast charging state is determined by the vehicle controller module assembly receiving a second connection signal sent by the battery management system.

[0076] By distinguishing between slow charging and fast charging states, and judging the charging mode according to different connection signals, the water pump can be started or stopped flexibly in different charging scenarios. The intelligent degree of electronic water pump maintenance during charging is effectively improved, and the compatibility and power management efficiency of the system are improved.

[0077] Preferably, in some embodiments of the application, when the whole vehicle is in a slow charging state, the CDU (Conversion & Distribution Unit, which refers to a high-voltage "electronic control" system integration of DC / DC converter, on-board charger, high-voltage junction box, etc.) sends a charging connection and charging control connected signal; when the whole vehicle is in a fast charging state, the BMS sends a fast charging gun connected signal.

[0078] Further, in some embodiments of the application, when the whole vehicle ends the charging state, it further includes:

[0079] The battery management system sends a charging completion signal to the whole vehicle controller module assembly;

[0080] The whole vehicle controller module assembly sends a high-voltage lowering instruction to the battery management system and re-monitors the shutdown time of each electronic water pump.

[0081] After charging is completed, the battery management system and the whole vehicle controller module assembly cooperate to complete the transmission of the charging signal, automatically cut off the high voltage, and re-monitor the electronic water pump, so as to ensure that the electronic water pump is effectively maintained, avoid the problem of cooling circuit blockage, and improve the performance and safety of the whole vehicle.

[0082] Preferably, in some embodiments of the application, when charging is completed and the user actively ends the high-voltage behavior, it is necessary to determine whether the whole vehicle needs to be lowered in high voltage according to the shutdown time of the current electronic water pump. During the charging process and the user's high-voltage process, the whole vehicle controller module assembly continues to count the shutdown time of each electronic water pump. When charging is completed and the user actively ends the high-voltage behavior, if there is an electronic water pump whose shutdown time exceeds the first threshold value, no high-voltage lowering instruction needs to be sent to the battery management system, and the corresponding electronic water pump is started according to the preset duty cycle through the PWM / LIN communication channel, so as to avoid unnecessary high-voltage lowering and raising operations.

[0083] Reference Figure 2 Another flowchart of an automobile electronic water pump self-starting maintenance method is provided for embodiments of the application, which includes:

[0084] The vehicle controller module assembly and the BMS are woken up through the vehicle-mounted TBOX, at this time the vehicle controller module assembly starts monitoring the shutdown time length of the electronic water pump; when the shutdown time length of a certain electronic water pump exceeds the preset value, the high-voltage switch closing instruction is issued to the BMS, and the electronic water pump is woken up through the PWM / LIN communication channel at this time, the vehicle is in the high-voltage state, the electronic water pump locally enters the self-maintenance mode, and the electronic water pump starts running at a certain speed; when the electronic water pump self-maintenance ends, the vehicle is plugged in for charging or the user actively turns on the high voltage, the electronic water pump self-maintenance mode is exited, the vehicle is turned off or the charging operation is performed, at this time the BMS performs the relay breaking or switching to the charging state operation.

[0085] In summary, the automobile electronic water pump self-starting maintenance method provided by the embodiments of the present application has the following beneficial effects: when the vehicle is in the OFF gear, the vehicle controller module assembly is woken up through the vehicle-mounted TBOX, and the vehicle controller module assembly is used as the master node to monitor the shutdown time of the electronic water pump in each cooling circuit of the vehicle, when the electronic water pump has not started for a certain period of time, the electronic water pump is forced to start running, thereby preventing the cooling circuit from being blocked due to long-term non-use of the vehicle, further preventing the failure problem that the electronic water pump cannot work normally, and improving the safety of the vehicle. In addition, the TBOX wakes up the vehicle controller module assembly, so that the vehicle has remote wake-up and control capability, thereby performing the electronic water pump automatic maintenance action without completely starting the vehicle, thereby saving the energy consumption of the vehicle.
