[0001] This invention relates to the field of thermal management technology for new energy vehicles, and particularly to an exhaust method and system, electronic equipment, and medium for PHEV vehicles. Background Technology

[0002] New energy vehicles are becoming increasingly popular. PHEV (Plug-in Hybrid Electric vehicle) is a type of new energy vehicle.

[0003] In PHEV vehicles, if the cooling system cannot be completely purged during vacuuming and then coolant is added, abnormal issues such as unusual noises during coolant circulation when the air conditioning is running may occur. Furthermore, this problem can occur not only when the vehicle is newly delivered but also after additional coolant has been added during later maintenance.

[0004] How to effectively bleed the cooling system of PHEV vehicles after adding coolant to avoid problems such as abnormal noises in the coolant circulation is a technical challenge that urgently needs to be solved. Summary of the Invention

[0064] Figure 1 This is a structural block diagram of a PHEV vehicle cooling system provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the overall process of a PHEV vehicle exhaust method provided in an embodiment of the present invention. Figure 1 and Figure 2 As shown, after adding coolant during maintenance, activating the venting mode using the method provided in this embodiment can accelerate the removal of air from the coolant, ensuring the normal operation of the vehicle's cooling system.

[0065] For vehicles to activate the exhaust mode for one-button exhaust, the following conditions must be met: a) The vehicle is in the ON position; b) The vehicle is not Ready; c) The vehicle is in a high-voltage state; d) The charging gun is not plugged into the vehicle; e) The discharge gun is not plugged into the vehicle.

[0066] The method flow provided in this embodiment includes:

[0067] 1) Users can access one-button exhaust via factory mode, diagnostic tool, or central control screen;

[0068] 2) If both the prerequisites and triggering conditions are met, the user is displayed a message (e.g., a pop-up reminder on the central control screen) stating: "After adding coolant during maintenance, activating the exhaust mode can accelerate the expulsion of internal air and ensure the normal operation of the vehicle's cooling system. Do not activate this function under normal driving conditions, as it may cause abnormal temperature control of the vehicle's air conditioning, battery, electric drive, and other temperature-controlled components. When adding coolant for the first time, it is recommended to continue the exhaust process for more than one hour. After the vehicle has been driven normally, it is still necessary to check intermittently and replenish the coolant in a timely manner." If the user selects "Confirm," the IVI sends a one-button exhaust activation request signal. If the user selects "Cancel" or there is no operation for more than a predetermined time (e.g., 5 seconds), the activation is canceled. If the prerequisites are not met, the process exits.

[0069] 3) The PDCU receives the one-button exhaust start request signal from the IVI, determines that the preconditions and trigger conditions are met, and sends a one-button exhaust status feedback signal: 0x1 Exhaust in progress. According to Table 1, the PDCU controls the opening of the control board switch three-way (electronic expansion valve on the board switch side) and the duty cycle of the engine side three-way (heater three-way water valve), controls the duty cycle of the heater water pump, front motor water pump, rear motor water pump, and battery water pump, and sends a one-button exhaust start signal to the EMS: Request received. The PDCU sends a one-button exhaust switch status feedback signal to the IVI: On.

[0070] 4) During the exhaust process, the PDCU shields the thermal management requests of the air conditioner (AC), power battery, motor, etc.

[0071] 5) When the EMS receives the one-button exhaust start signal from the PDCU, it controls the duty cycle of the engine water pump and intercooler water pump according to Table 1 and reports the fault status of the engine water pump and intercooler water pump to the PDCU.

[0072] 6) Fault status of PDCU receiver board replacement T-connector, engine side T-connector, heater water pump, front motor water pump, rear motor water pump, battery water pump, engine water pump, and intercooler water pump; if the relevant water pump valve malfunctions during the exhaust process and the exhaust ends (meeting the exit conditions), send a one-key exhaust status feedback signal: 0x2 exhaust fault, the signal lasts for 1 minute, and then returns to 0x0 not started.

[0073] 7) If the relevant water pumps and valves are functioning properly during the venting process and venting is completed (meeting the exit conditions), send a one-key venting feedback signal: 0x3 Venting completed. The signal lasts for 1 minute, after which the feedback signal returns to 0x0 Not started.

[0074] 8) IVI receives one-touch exhaust feedback signals from the PDCU: Signal 0x1 Exhaust in progress, "Exhaust in progress" is constantly displayed next to the one-touch exhaust soft switch; Signal 0x2 Exhaust fault, displays information to the user (e.g., a pop-up reminder on the central control screen) "Conditions not met, cannot start the coolant exhaust mode for maintenance", the display disappears after a predetermined time (e.g., 3 seconds); Signal 0x3 Exhaust completed, displays information to the user (e.g., a pop-up reminder on the central control screen) "Exhaust execution closed, exhaust effect needs to be confirmed on the actual vehicle", the user confirms or closes the pop-up to exit, the display disappears after a predetermined time (e.g., 3 seconds);

[0075] 9) One-key exhaust shutdown conditions include: a) the vehicle is in OFF position; b) the vehicle is Ready; c) vehicle status: the vehicle is in a non-high voltage state; d) the vehicle is plugged into the charging gun; e) the vehicle is plugged into the discharge gun; f) the IVI one-key exhaust shutdown request is received; g) the exhaust time has reached 1 hour.

[0076] Table 1 Component Control During Exhaust Mode

[0077]

[0078] Note: During the initial venting stage, the duty cycle can be appropriately increased to improve the pump's flow rate and speed, and quickly expel the gas from the system. When venting is nearing completion, the duty cycle can be gradually decreased to reduce the pump's flow rate and speed, avoiding excessive impact or damage to the system.

[0079] In this embodiment of the invention, for ease of description, the following description uses the vehicle's PDCU power domain controller as the execution subject, but it can also be other electronic devices, vehicle controllers, etc. that can achieve the same function.
