[0049] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0050] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0051] The embodiment of the present invention provides a vehicle heat dissipation control method, referring to Figure 1 , Figure 1 It is a flow chart of the first embodiment of the vehicle heat dissipation control method of the present invention.

[0052] In this embodiment, the vehicle heat dissipation control method includes the following steps, step S10 to step S30:

[0053] Step S10: Obtain the SOC core temperature and PCB board temperature of the vehicle, and determine whether there is a heartbeat signal that meets preset requirements.

[0054] It should be noted that the execution subject of this embodiment can be a computer server device with data processing, network communication and program running functions used in the vehicle, such as a vehicle controller (VCU), or an electronic device capable of realizing the above functions, a vehicle heat dissipation control device, etc. The following takes a vehicle heat dissipation control device including a vehicle controller as an example to illustrate this embodiment and the following embodiments.

[0055] It should be understood that the above SOC core temperature T SOC It can be that the SOC transmits the SOC core temperature T through a communication interface (such as IIC, SPI, etc.) SOC To MCU, MCU transmits it to PDCU through vehicle CAN, and PDCU executes different liquid cooling strategies according to the situation. PCB board temperature T board It can be the PCB board temperature T obtained by MCU from the sensor chip through the communication interface (such as IIC, SPI, etc.) board .

[0056] It should be explained that the heartbeat signal is a small data packet sent by the MCU to other components in the system (such as other ECUs, sensors or controllers) at fixed intervals. These data packets usually do not contain a large amount of valid data, and their main purpose is to confirm the connection status and detect potential communication failures.

[0057] It should be noted that if there is no heartbeat signal that meets the preset requirements, it means that the obtained SOC core temperature is invalid. Conversely, if there is a heartbeat signal that meets the preset requirements, it means that the obtained SOC core temperature is valid. The above-mentioned heartbeat signal that meets the preset requirements can be a heartbeat signal that exists within a certain period of time.

[0058] Step S20: If there is a heartbeat signal that meets the preset requirements, the target liquid cooling strategy of the vehicle is determined according to the SOC core temperature and / or the PCB board temperature.

[0059] It should be noted that when T SOC <T 1 To achieve the appropriate temperature, the liquid cooling strategy remains unchanged, and the existing coolant flow and coolant temperature remain unchanged. 1 is the first preset temperature value; when T SOC ≥T 1 To warn the temperature, start the first-level liquid cooling strategy, request to increase the coolant flow △Q1, and reduce the coolant temperature △T 1 When T SOC ≥T 2 For dangerous temperatures, start the secondary liquid cooling strategy, request to increase the coolant flow △Q2, and reduce the coolant temperature △T 2 , T 2 is the second preset temperature value.

[0060] When T board <T 3 To achieve the appropriate temperature, the liquid cooling strategy remains unchanged, and the existing coolant flow and coolant temperature remain unchanged. 3 is the third preset temperature value; when T board ≥T 3 To warn the temperature, the first-level liquid cooling strategy is activated, requesting to increase the coolant flow rate △Q1 and reduce the coolant temperature △T1; when T board ≥T 4 The temperature is dangerous, so the secondary liquid cooling strategy is activated, and the coolant flow rate is increased by △Q2, and the coolant temperature is reduced by △T2. 4 It is the fourth preset temperature value.

[0061] It needs to be explained that T 1 、T 2 、T 3 、T 4 , △Q1, △Q2, △T1 , △T 2 It can be configured according to the temperature characteristics of the SOC chip and the PCB board. 1 <T 2 , T 3 <T 4 , △Q1<△Q2, △T 1 <△T 2 .

[0062] It should be understood that the SOC core temperature T SOC and PCB board temperature T board It is an OR relationship, that is, if any temperature is abnormal, the liquid cooling strategy needs to be changed.

[0063] For example, refer to Figure 2 , Figure 2 Schematic diagram of target liquid cooling strategy selection in the vehicle heat dissipation control method of the present invention. 1 is the first preset temperature value, T 2 is the second preset temperature value, T 3 is the third preset temperature value, T 4 is the fourth preset temperature value, T SOC Indicates the SOC core temperature, T board Indicates the PCB board temperature, N indicates no, and Y indicates yes. If there is a heartbeat signal that meets the preset requirements, it is determined whether the SOC core temperature is greater than or equal to the first preset temperature value; if the SOC core temperature is greater than or equal to the first preset temperature value, it is determined whether the SOC core temperature is greater than or equal to the second preset temperature value; if the SOC core temperature is greater than or equal to the second preset temperature value, the secondary liquid cooling heat dissipation strategy is used as the target liquid cooling strategy for the vehicle. If the SOC core temperature is less than the first preset temperature value, it is determined whether the PCB board temperature is greater than or equal to the third preset temperature value; if the PCB board temperature is greater than or equal to the third preset temperature value, it is determined whether the PCB board temperature is greater than or equal to the fourth preset temperature value; if the PCB board temperature is greater than or equal to the fourth preset temperature value, the secondary liquid cooling heat dissipation strategy is used as the target liquid cooling strategy for the vehicle. If the SOC core temperature is less than the second preset temperature value, it is determined whether the PCB board temperature is greater than or equal to the fourth preset temperature value; if the PCB board temperature is greater than or equal to the fourth preset temperature value, the second-level liquid cooling heat dissipation strategy is used as the target liquid cooling strategy of the vehicle; if the PCB board temperature is less than the fourth preset temperature value, the first-level liquid cooling heat dissipation strategy is used as the target liquid cooling strategy of the vehicle. If the PCB board temperature is less than the third preset temperature value, the existing coolant flow and coolant temperature are maintained.

[0064] Step S30: executing the target liquid cooling strategy, and sending heat dissipation prompt information according to the execution time of the target liquid cooling strategy.

[0065] It should be noted that in order to further ensure the safety of the heat dissipation process, if the execution time of the target liquid cooling strategy exceeds the preset heat dissipation time and the SOC core temperature T SOC and PCB board temperature T board If the temperature does not return to the appropriate level, the SOC is turned off and a cooling fault message is reported to the vehicle via CAN. If the execution time of the target liquid cooling strategy does not exceed the preset cooling time and the SOC core temperature T SOC and PCB board temperature T board When the temperature returns to a suitable level, a prompt message indicating successful cooling will be sent.

[0066] This embodiment discloses obtaining the SOC core temperature and PCB board temperature of the vehicle, and determining whether there is a heartbeat signal that meets the preset requirements; if there is a heartbeat signal that meets the preset requirements, determining the target liquid cooling strategy of the vehicle according to the SOC core temperature and / or the PCB board temperature; executing the target liquid cooling strategy, and sending heat dissipation prompt information according to the execution time of the target liquid cooling strategy. Since this embodiment determines the target liquid cooling strategy of the vehicle according to the SOC core temperature and / or the PCB board temperature when there is a heartbeat signal that meets the preset requirements, then executes the target liquid cooling strategy, and sends heat dissipation prompt information according to the execution time of the target liquid cooling strategy, compared to the prior art, this embodiment ensures the safety of the heat dissipation process, while effectively avoiding unnecessary loads on the vehicle water cooling system, thereby reducing heat dissipation energy consumption.

[0067] refer to Figure 3 , Figure 3 It is a flow chart of the second embodiment of the vehicle heat dissipation control method of the present invention.

[0068] Based on the above first embodiment, in this embodiment, step S10 includes steps S101 to S104:

[0069] Step S101: Obtain the SOC core temperature and PCB board temperature of the vehicle, and determine whether there is a heartbeat signal within a preset time.

[0070] Step S102: If there is no heartbeat signal within the preset time, restart the power management chip of the vehicle, determine whether there is a heartbeat signal within the preset time, and record the number of restarts of the power management chip of the vehicle.

[0071] Step S103: If there is no heartbeat signal within the preset time, execute the step of restarting the power management chip of the vehicle, determine whether there is a heartbeat signal within the preset time, and record the number of restarts of the power management chip of the vehicle until the number of restarts is equal to the preset number or there is a heartbeat signal within the preset time.

[0072] Step S104: determining whether there is a heartbeat signal that meets preset requirements based on the number of restarts and whether there is a heartbeat signal within the preset time.

[0073] It should be noted that when the number of restarts is less than or equal to the preset number and there is a heartbeat signal within the preset time, it means that there is a heartbeat signal that meets the preset requirements; when the number of restarts is equal to the preset number and there is no heartbeat signal within the preset time, it means that there is no heartbeat signal that meets the preset requirements.

[0074] It is understandable that after the step of obtaining the SOC core temperature and PCB board temperature of the vehicle and determining whether there is a heartbeat signal within the preset time, it also includes: if there is a heartbeat signal within the preset time, it means that there is a heartbeat signal that meets the preset requirements.

[0075] It should be noted that the MCU monitors the heartbeat signal. If the preset time t k When there is no heartbeat signal, the SOC temperature information is considered invalid, and the power management chip (i.e., SOC PMIC) is restarted. If it does not recover, it will continue to restart. After the preset number of times N, if t k If there is still no heartbeat signal, turn off the SOC PMIC and report the SOC fault to the vehicle through CAN; if the heartbeat signal is restored and the time is within t k According to the SOC core temperature T SOC and PCB board temperature T board To determine the target liquid cooling strategy for the vehicle.

[0076] It should be understood that the above-mentioned preset number of times and preset time may be custom settings when the vehicle leaves the factory, and this embodiment does not impose any limitation on this.

[0077] This embodiment discloses obtaining the SOC core temperature and PCB board temperature of the vehicle, and determining whether there is a heartbeat signal within a preset time; if there is no heartbeat signal within the preset time, restarting the power management chip of the vehicle, determining whether there is a heartbeat signal within the preset time, and recording the number of restarts of the power management chip of the vehicle; if there is no heartbeat signal within the preset time, executing the steps of restarting the power management chip of the vehicle, determining whether there is a heartbeat signal within the preset time, and recording the number of restarts of the power management chip of the vehicle, until the number of restarts is equal to the preset number or there is a heartbeat signal within the preset time; determining whether there is a heartbeat signal that meets the preset requirements based on the number of restarts and whether there is a heartbeat signal within the preset time. Compared with the prior art, this embodiment ensures the validity of the SOC core temperature by determining whether there is a heartbeat signal that meets the preset requirements, thereby improving the reliability of the target liquid cooling strategy selection.

[0078] refer to Figure 4 , Figure 4 It is a flow chart of the third embodiment of the vehicle heat dissipation control method of the present invention.

[0079] Based on the above embodiments, in this embodiment, step S30 includes steps S301 to S302:

[0080] Step S301: executing the target liquid cooling strategy, and determining a preset heat dissipation time according to the level of the target liquid cooling strategy.

[0081] Step S302: When the execution time of the target liquid cooling strategy is greater than the preset heat dissipation time, the SOC core temperature is greater than or equal to the first preset temperature value, and the PCB board temperature is greater than or equal to the third preset temperature, a heat dissipation prompt message is sent according to the level of the target liquid cooling strategy.

[0082] It should be noted that for the PCB board temperature T board After starting the first-level liquid cooling strategy, if time t 1 The internal warning temperature cannot return to the appropriate temperature, the SOC is turned off, and the first-level cooling fault is reported to the entire vehicle through CAN; after the second-level liquid cooling strategy is started, if the time t 2 The dangerous internal temperature cannot return to a suitable temperature, the SOC is shut down, and a second-level heat dissipation fault is reported to the entire vehicle through CAN.

[0083] For the SOC core temperature T SOC After starting the first-level liquid cooling strategy, if time t 3 The internal warning temperature cannot return to the appropriate temperature, the SOC is turned off, and the first-level cooling fault is reported to the entire vehicle through CAN; after the second-level liquid cooling strategy is started, if the time t 4The internal dangerous temperature cannot return to a suitable temperature, the SOC is shut down, and a second-level heat dissipation fault is reported to the entire vehicle through CAN.

[0084] It is understandable that the above t 1 ,t 2 ,t 3 and t 4 It can be based on custom settings, and this embodiment does not limit this.

[0085] It should be understood that if the execution time of the target liquid cooling strategy does not exceed the preset heat dissipation time and the SOC core temperature T SOC and PCB board temperature T board When the temperature returns to a suitable level, a prompt message indicating successful cooling will be sent.

[0086] This embodiment discloses obtaining the SOC core temperature and PCB board temperature of the vehicle, and determining whether there is a heartbeat signal that meets the preset requirements; if there is a heartbeat signal that meets the preset requirements, determining the target liquid cooling strategy of the vehicle according to the SOC core temperature and / or the PCB board temperature; executing the target liquid cooling strategy, and determining the preset heat dissipation time according to the level of the target liquid cooling strategy; when the execution time of the target liquid cooling strategy is greater than the preset heat dissipation time, the SOC core temperature is greater than or equal to the first preset temperature value, and the PCB board temperature is greater than or equal to the third preset temperature, sending heat dissipation prompt information according to the level of the target liquid cooling strategy.
