[0002] The electronic water pump is a core component of the thermal management system in new energy vehicles. The electronic water pump is used to circulate coolant, thereby regulating the temperature of the motor cooling circuit, battery cooling circuit, and engine cooling circuit to ensure that the vehicle does not overheat and to ensure the performance and safety of the entire vehicle.

[0003] In order to ensure the safety of the entire vehicle, the existing technology combines the electronic water pump's own monitoring function with a certain control strategy to ensure the normal operation of the electronic water pump. For example, the water pump is precisely controlled through the sensorless FOC (Field-Oriented Control) algorithm. Some other technologies adjust the water pump flow in real time according to changes in the cooling circuit temperature and driving conditions to achieve better temperature control effects. In addition, some electronic water pump systems have fault diagnosis capabilities, which can detect abnormal problems of the electronic water pump in real time and send alarms to users. However, the above solutions focus on the operation control and problem detection of the electronic water pump when the vehicle is started to ensure the performance and safety of the vehicle.

When the electronic water pump has not been started within a certain period of time, the electronic water pump is forced to start running, thereby preventing the cooling circuit blockage caused by long-term non-use of the vehicle, further preventing the failure of the electronic water pump to work normally, and improving the safety of the vehicle. In addition, TBOX awakens the vehicle controller module assembly, so that the vehicle has the ability to remotely wake up and control, so that when performing the automatic maintenance action of the electronic water pump, there is no need to fully start the vehicle, saving the energy consumption of the vehicle.

In addition, when the vehicle is in the ON gear, by stopping the operation of the electronic water pump, the resources of the high-voltage system are concentrated for driving and key systems, the load of the high-voltage system is reduced, and system problems caused by uneven power distribution during vehicle operation are avoided, thereby improving the safety of the vehicle.

[0042] In order to ensure the safety of the whole vehicle, the existing technology combines the self-monitoring function of the electronic water pump with a certain control strategy to ensure the normal operation of the electronic water pump. For example, the water pump is precisely controlled through the sensorless FOC (Field-Oriented Control) algorithm. Some other technologies adjust the water pump flow in real time according to the changes in the cooling circuit temperature and driving conditions to achieve better temperature control effects. In addition, some electronic water pump systems have fault diagnosis capabilities, which can detect abnormal problems of the electronic water pump in real time and send alarm prompts to users. However, the above solution focuses on the operation regulation and problem detection of the electronic water pump when the whole vehicle is started to ensure the performance and safety of the whole vehicle, and does not consider the technical problem that the electronic water pump cannot work due to blockage of the cooling circuit when the electronic water pump has not been used for a long time.

[0043] In order to solve the above technical problems, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Embodiment 1

[0045] Please refer to Figure 1 , is a method for maintaining an automotive electronic water pump self-starting provided by an embodiment of the present application, including S10 to S30, specifically:

[0046] S10: When the vehicle is in the OFF position, the vehicle controller module assembly is awakened through the on-board TBOX.

[0047] Preferably, in some embodiments of the present application, the OFF position refers to that the power supply or ignition switch of the entire vehicle is in the off state. For example, in an electric vehicle or a hybrid vehicle, the OFF position usually means 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 entire vehicle (such as the power system, air-conditioning system, etc.) usually stop running, but some low-voltage electrical equipment may still be awakened by external signals (such as the on-board TBOX) and perform certain operations.

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

[0049] Preferably, in some embodiments of the present application, when the vehicle controller module assembly is awakened by the on-board TBOX, certain preset conditions can be set in the TBOX, such as when the vehicle is in the OFF gear, or in response to instructions sent by the user to the TBOX through external remote control (such as a mobile phone application, a remote server, etc.), thereby waking up the vehicle controller module assembly.

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

[0051] Preferably, in some embodiments of the present application, the cooling circuits corresponding to the electronic water pumps include but are 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. The vehicle controller module assembly needs to monitor the electronic water pumps corresponding to all cooling circuits in real time, and independently count the downtime of each electronic water pump, so as to ensure the smooth flow of each cooling circuit.

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

[0053] S30: When the shutdown time of the electronic water pump is greater than a first threshold, 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, controlling the high voltage on the vehicle through the vehicle controller module assembly includes:

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

[0056] Through the vehicle controller module assembly, a high-voltage switch closing instruction is sent 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 status of the battery pack and provide a power source for the entire vehicle.

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

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

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

[0061] The corresponding electronic water pump is started according to a preset duty cycle through the vehicle controller module assembly.

[0062] By waking up the electronic water pump through the vehicle controller module assembly and starting it according to the preset duty cycle, the water pump startup process can be accurately controlled. In addition, controlling the speed of the electronic water pump by the preset duty cycle can effectively prevent over-operation, improve energy efficiency, and reduce power consumption and wear of the water pump during startup.

[0063] Preferably, in some embodiments of the present application, when it is monitored that the electronic water pump corresponding to any cooling circuit has not been started for a certain period of time, if other electronic water pumps are already in the started state, causing the entire vehicle to be in the upper high-voltage state, then it is avoided to repeatedly send the closing high-voltage switch command to the battery management system, and the electronic water pump whose shutdown time has exceeded the first threshold is directly started.

[0064] Furthermore, in some embodiments of the present application, after starting the corresponding electronic water pump, the method further includes:

[0065] When a first preset condition is met, the corresponding electronic water pump is stopped by the vehicle controller module assembly;

[0066] The first preset condition includes: the electronic water pump has met the first preset time required to run and the vehicle controller module assembly monitors other high-voltage behaviors during the period when the electronic water pump is in the startup state.

[0067] By setting the first preset condition to control the stopping behavior of the electronic water pump, when the preset operating time is met or other high-pressure behaviors are detected, the operating state of the water pump is intelligently controlled to avoid unnecessary or inappropriate operation that may cause abnormal status of the entire vehicle. This not only reduces energy waste, but also achieves more intelligent maintenance control.

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

[0069] Preferably, in some embodiments of the present application, when all currently started electronic water pumps have satisfied the first preset running time required, the corresponding electronic water pump is stopped and a high-voltage command is sent to the BMS through the vehicle controller module assembly to disconnect the main positive and main negative relays, while continuing to monitor the shutdown time of the electronic water pumps of each cooling circuit.

[0070] Furthermore, in some embodiments of the present application, the other high-voltage behaviors include: the entire vehicle enters a charging state, the user actively increases the high voltage through an integrated braking control system, and the entire vehicle is in the ON gear.

[0071] When the vehicle is in the charging state or the user actively turns on the high voltage, the electronic water pump is stopped to avoid redundant electronic water pump self-maintenance actions that lead to increased wear of the electronic water pump and extend the life of the electronic water pump. In addition, when the vehicle is in the ON gear, by stopping the operation of the electronic water pump, the resources of the high-voltage system are concentrated on driving and key systems, reducing the load of the high-voltage system, avoiding system problems caused by uneven power distribution during vehicle operation, and improving vehicle safety.

[0072] Preferably, in some embodiments of the application, when the user actively turns on the high pressure, the integrated brake control system (IBC) sends a user remote high pressure request signal or the vehicle key gear is in the ON gear. At this time, the vehicle controller module assembly does not need to send a high pressure 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] Furthermore, in some embodiments of the present application, when the vehicle enters the charging state, it also includes:

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

[0075] Among them, the slow charging state is determined by the vehicle controller module assembly receiving a first connection signal sent by the CDU of the vehicle; 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 based on different connection signals, the water pump can be flexibly started or stopped in different charging scenarios. This effectively improves the intelligence of electronic water pump maintenance issues during the charging process and improves the system's compatibility and power management efficiency.

[0077] Preferably, in some embodiments of the present 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 integrating functions such as a DC / DC converter, an on-board charger, and a high-voltage junction box) sends a charging connection and charging control connection signal; when the whole vehicle is in a fast charging state, the BMS sends a fast charging gun connected signal.

[0078] Furthermore, in some embodiments of the present application, after the vehicle ends the charging state, it further includes:

[0079] Sending a charging completion signal to the vehicle controller module assembly through the battery management system;

[0080] A high-voltage instruction is sent to the battery management system through the vehicle controller module assembly, and the shutdown time of each electronic water pump is re-monitored.

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

[0082] Preferably, in some embodiments of the present application, when charging is completed and the user actively turns on the high voltage, it is necessary to determine whether the high voltage needs to be lowered for the entire vehicle based on the downtime of the current electronic water pump. During the charging process and the process of the user turning on the high voltage, the vehicle controller module assembly still continues to count the downtime of each electronic water pump. When charging is completed and the user actively turns on the high voltage, if there is an electronic water pump whose downtime exceeds the first threshold, there is no need to send a high voltage lowering instruction to the battery management system. The corresponding electronic water pump is started directly through the PWM / LIN communication channel according to the preset duty cycle, thereby avoiding unnecessary high voltage upper and lower operations.

[0083] refer to Figure 2 , another flow chart of a method for self-starting and maintaining an automotive electronic water pump is provided in the embodiment of the present application, which includes:

[0084] The vehicle controller module assembly and BMS are woken up through the on-board TBOX through the network respectively. At this time, the vehicle controller module assembly starts monitoring the downtime of the electronic water pump; when the downtime of a certain electronic water pump exceeds the preset value, a command to close the high-voltage switch is sent to the BMS, and the electronic water pump is woken up through the PWM / LIN communication channel. At this time, the whole vehicle is in the high-voltage state, and the electronic water pump enters the self-maintenance mode locally, and the electronic water pump starts and runs at a certain speed; when the electronic water pump self-maintenance is completed, the whole 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 whole vehicle turns off the high voltage or performs charging operations, and the BMS correspondingly executes the operation of disconnecting the relay or switching to the charging state.

[0085] In summary, the self-starting maintenance method for an automobile electronic water pump provided in the embodiment of the present application has the following beneficial effects: when the vehicle is in the OFF gear, the vehicle controller module assembly is awakened by the on-board TBOX, and the vehicle controller module assembly is used as the main control node to monitor the downtime of the electronic water pumps of each cooling circuit in the vehicle. When the electronic water pump has not been started within a certain period of time, the electronic water pump is forced to start and run, thereby preventing the cooling circuit blockage caused by long-term non-use of the vehicle, further preventing the failure of the electronic water pump to work normally, and improving the safety of the vehicle. In addition, TBOX awakens the vehicle controller module assembly, so that the vehicle has the ability to remotely wake up and control, so that when performing the automatic maintenance action of the electronic water pump, there is no need to fully start the vehicle, saving the energy consumption of the vehicle.
