[0002] With the advancement of the "four modernizations" of vehicles, electric vehicles are developing rapidly. To meet the diverse needs of users, vehicle software troubleshooting, software customization updates, and breakthroughs in power battery technology have become important goals in vehicle development. Since the working state of power batteries is greatly affected by ambient temperature, effective heat dissipation is required to ensure that the power batteries remain in good working condition in high-temperature environments. Therefore, how to effectively control battery thermal management when equipped with OTA (Over The Air Technology) upgrade technology has become a research direction for power batteries.

[0003] In the related technologies, most of them are to perform thermal management control on the vehicle under normal circumstances, or only perform OTA upgrade management on the vehicle, but do not consider thermal management control of the vehicle under OTA upgrade management.

[0004] However, thermal management control is only performed on the vehicle under normal circumstances. At this time, the application message of the vehicle is prohibited during the OTA upgrade state, that is, the functional signals related to thermal management are prohibited, which makes the vehicle unable to perform thermal management functions in this state, which urgently needs to be solved. Summary of the Invention

[0005] The present application provides a vehicle thermal management control method, device, vehicle and storage medium to solve the problem that when the vehicle has actual cooling needs, the thermal management control system cannot receive the cooling request signal or the relevant request signal is forced to be interrupted during the cooling process, causing the controller to be in a high temperature state for a long time, affecting the service life of the controller and reducing safety performance.

[0006] The first aspect of the present application provides a thermal management control method for a vehicle, comprising the following steps: determining whether the thermal management control system is in a preset cooling execution state; if the thermal management control system is not in the preset cooling execution state, controlling at least one controller to be upgraded of the vehicle to enter the OTA upgrade process, and after the upgrade of the at least one controller to be upgraded is completed, sending an exit OTA mode instruction to the thermal management control system; and if the thermal management control system is in the preset cooling execution state, identifying the current cooling request signal source, and determining the heat dissipation controller according to the current cooling request signal source, and when the heat dissipation controller is not included in the at least one controller to be upgraded, directly controlling the at least one controller to be upgraded to enter the OTA upgrade process.

[0007] According to the above technical means, the controller that needs cooling is identified through the vehicle thermal management demand signal and a corresponding upgrade strategy is formulated, thereby effectively avoiding the situation where the vehicle is unable to cool and dissipate heat after entering OTA mode due to the prohibition of thermal management function signals, thereby improving the vehicle's service life and safety performance.

[0008] Furthermore, in one embodiment of the present application, after determining the heat dissipation controller according to the current cooling request signal source, it also includes: if the heat dissipation controller is included in the at least one controller to be upgraded, then determining whether the heat dissipation controller supports dual-partition flashing; if the heat dissipation controller supports the dual-partition flashing, then directly controlling the at least one controller to be upgraded to enter the OTA upgrade process; otherwise, sending a maintain current cooling state instruction to the thermal management control system, so that the thermal management control system maintains the current water pump flow and flow rate state for heat dissipation, and controls the heat dissipation controller to enter the OTA upgrade process.

[0015] According to the above technical means, after the upgrade is completed, by determining whether the controller still has cooling requirements, the controller can be cooled and controlled, thereby increasing the service life of the controller and improving the safety of the controller.

When the thermal management control system is in the preset cooling execution state, the current cooling request signal source is identified and the heat dissipation controller is determined. When at least one controller to be upgraded does not include a heat dissipation controller, the at least one controller to be upgraded is directly controlled to enter the OTA upgrade process. This solves the problem that when the vehicle has actual cooling needs, the thermal management control system cannot receive the cooling request signal or the relevant request signal is forced to be interrupted during the cooling process, causing the controller to remain in a high temperature state, affecting the service life of the controller and reducing safety performance.

[0033] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0034] The following describes the thermal management control method, device, vehicle and storage medium of the vehicle according to the embodiment of the present application with reference to the accompanying drawings. In response to the problem mentioned in the above background technology that when the vehicle has actual cooling demand, the thermal management control system cannot receive the cooling request signal or the relevant request signal is forced to be interrupted during the cooling process, thereby causing the controller to be in a high temperature state for a long time, affecting the service life of the controller and reducing the safety performance, the present application provides a thermal management control method for a vehicle, in which, when the thermal management control system is not in a preset cooling execution state, at least one controller to be upgraded of the vehicle is controlled to enter the OTA upgrade process, and after the upgrade is completed, an exit OTA mode instruction is sent, and when the thermal management control system is in a preset cooling execution state, the current cooling request signal source is identified and the heat dissipation controller is determined, and when the heat dissipation controller is not included in at least one controller to be upgraded, at least one controller to be upgraded is directly controlled to enter the OTA upgrade process. This solves the problem that when the vehicle has actual cooling needs, the thermal management control system cannot receive the cooling request signal or the relevant request signal is forced to be interrupted during the cooling process, causing the controller to be in a continuous high-temperature state, affecting the service life of the controller and reducing safety performance. The controller that needs to be cooled is identified through the vehicle thermal management demand signal and a corresponding upgrade strategy is formulated, which effectively avoids the situation where the vehicle cannot be cooled and dissipated after entering the OTA mode due to the prohibition of the thermal management function signal, thereby improving the service life and safety performance of the vehicle.

[0035] Specifically, before introducing the embodiments of the present application, we first introduce the relevant modules involved in the OTA system architecture and the vehicle network architecture used in the embodiments of the present application, such as Figure 1 and Figure 2 As shown, Figure 1 The OTA system architecture is shown, consisting of an OTA server, an OTA Master, at least one OTA Sub-Master, and several controllers with upgrade requirements. The OTA Master is responsible for controlling the entire OTA upgrade process and instructing each OTA Sub-Master to upgrade its own upgrade controllers.

[0036] Furthermore, Figure 2The vehicle network architecture is shown, which includes at least one gateway, an OTA main control module OTA Master and several controllers. Each controller sends or receives functional signals on the network segment to which it belongs, and the gateway is responsible for forwarding all signals to the required network segment. For example, in an embodiment of the present application, the battery and motor at 01 and 02 first send a cooling request signal and a temperature signal to the gateway when they are at high temperature. At this time, the gateway forwards the two signals to the thermal management control system at 03 and the OTA Master at 06; secondly, after receiving the cooling request signal and the temperature signal value, the thermal management control system determines whether the cooling conditions are met. If so, it controls the water pump at 04 to request water cooling for the battery and motor. The OTA Master can determine whether there is a cooling request signal and a corresponding temperature value signal when necessary, and determine which controllers are at high temperatures and the status of the controllers requesting cooling based on the definition of the corresponding signal. Before entering the upgrade, OTA Master can also send control instructions for entering OTA mode and thermal management control demand signals under OTA mode to the gateway through the network. The gateway then forwards the OTA mode signal and the thermal management control demand signal under OTA mode to the thermal management control system at 03. After receiving the signal, the thermal management control system enters the special working state of OTA mode according to the specific signal request.

[0037] Specifically, Figure 3 A flow chart of a vehicle thermal management control method provided in an embodiment of the present application.

[0038] like Figure 3 As shown, the vehicle thermal management control method includes the following steps:

[0039] In step S301 , it is determined whether the thermal management control system is in a preset cooling execution state.

[0040] Furthermore, in one embodiment of the present application, before determining whether the thermal management control system is in a preset cooling execution state, it also includes: determining whether the OTA upgrade instruction of at least one controller to be upgraded meets the OTA upgrade preconditions; if the OTA upgrade preconditions are met, sending an instruction to enter the OTA mode to the thermal management control system.

[0041] Specifically, in an embodiment of the present application, after receiving the cooling request signal of the controller to be upgraded, the thermal management control system needs to determine whether the OTA upgrade instruction of at least one controller to be upgraded meets the OTA upgrade precondition. The precondition first needs to define the temperature value signal and cooling request signal of each controller to be upgraded with thermal management requirements when it is working; secondly, if the controller to be upgraded only supports CAN (Controller Area Network) network communication, the underlying software of the controller to be upgraded needs to design special processing for the standard protocol stack, that is, when the controller to be upgraded receives the functional addressing or physical addressing diagnostic message service sent by the host computer, the underlying software of the controller to be upgraded needs to keep the temperature value signal and the cooling request signal normal, and only prohibit other non-diagnostic message signals to ensure that OTAMaster and the thermal management control system can receive them normally; if the controller supports Ethernet communication, the temperature value signal and the cooling request signal can be designed as DDS (Direct Digital Synthesis) communication protocol or other non-CAN communication protocols, that is, they are not prohibited by the functional addressing or physical addressing diagnostic message service sent by the host computer. At this time, it is determined that the OTA upgrade precondition is met. After the OTA upgrade preconditions are met, an instruction to enter OTA mode is sent to the thermal management control system. After the thermal management control system receives the instruction to enter OTA mode, the gateway forwards the non-diagnostic message signal function sent by each controller to be upgraded, and cannot be restricted by the functional addressing or physical addressing diagnostic message service sent by the host computer.

[0042] In step S302, if the thermal management control system is not in the preset cooling execution state, at least one controller to be upgraded of the vehicle is controlled to enter the OTA upgrade process, and after the upgrade of at least one controller to be upgraded is completed, an exit OTA mode instruction is sent to the thermal management control system.

[0043] Specifically, in the embodiments of the present application, Figure 4 As shown, if the thermal management control system is not in the preset cooling execution state, it means that the controller to be upgraded does not need to be cooled at this time. At the same time, because the vehicle is performing OTA upgrades in a static state, the vehicle will not generate load heat. It can be determined that the vehicle is in a safe state. At least one controller to be upgraded in the vehicle can be directly controlled to enter the OTA upgrade process, and after the upgrade of at least one controller to be upgraded is completed, an exit OTA mode instruction is sent to the thermal management control system.

[0044] In step S303, if the thermal management control system is in a preset cooling execution state, the current cooling request signal source is identified, and the heat dissipation controller is determined based on the current cooling request signal source. When at least one controller to be upgraded does not include a heat dissipation controller, at least one controller to be upgraded is directly controlled to enter the OTA upgrade process.

[0045] Furthermore, in one embodiment of the present application, after sending an instruction to maintain the current cooling state to the thermal management control system so that the thermal management control system maintains the current water pump flow and flow rate state for heat dissipation and controls the heat dissipation controller to enter the OTA upgrade process, it also includes: sending an instruction to exit OTA mode to the thermal management control system; receiving a status signal of at least one controller to be upgraded, and when the status signal is in a preset cooling execution state, controlling at least one controller to be upgraded to perform a cooling action.

[0046] Specifically, in an embodiment of the present application, if the thermal management control system is in a preset cooling execution state, it means that the temperature of at least one controller to be upgraded is too high and needs to be cooled. It is necessary to identify the current cooling request signal source and determine whether at least one controller to be upgraded includes a heat dissipation controller based on the current cooling request signal source. When at least one controller to be upgraded does not include a heat dissipation controller, directly control at least one controller to be upgraded to enter the OTA upgrade process. Since the diagnostic message service of the embodiment of the present application does not silence the cooling request signal and the temperature value signal, it is possible to directly control at least one controller to be upgraded to enter the OTA upgrade process without interrupting the operation of the water pump.

[0047] Furthermore, in one embodiment of the present application, after determining the heat dissipation controller according to the current cooling request signal source, it also includes: if at least one controller to be upgraded includes a heat dissipation controller, then determining whether the heat dissipation controller supports dual-partition flashing; if the heat dissipation controller supports dual-partition flashing, then directly controlling at least one controller to be upgraded to enter the OTA upgrade process; otherwise, sending an instruction to maintain the current cooling state to the thermal management control system, so that the thermal management control system maintains the current water pump flow and flow rate state for heat dissipation, and controls the heat dissipation controller to enter the OTA upgrade process.

[0048] Specifically, in an embodiment of the present application, if in the OTA upgrade mode, there is at least one controller to be upgraded that includes a heat dissipation controller, the OTA main control module needs to determine whether the heat dissipation controller supports A / B dual-partition flashing. If the heat dissipation controller supports A / B dual-partition flashing, it directly controls at least one controller to be upgraded to enter the OTA upgrade process. At this time, since the heat dissipation controller supports A / B dual-partition flashing, when flashing the software, only the software of the non-running partition needs to be flashed, and it does not affect the sending of the cooling request signal and temperature value signal of the controller to be upgraded.

[0049] Furthermore, if the heat dissipation controller of the embodiment of the present application does not support A / B dual partition flashing, the OTA main control module sends an instruction to maintain the current cooling state to the thermal management control system, so that when the thermal management control system receives the instruction to maintain the current cooling state, in the OTA upgrade mode, the thermal management control system maintains the current water pump flow and flow rate state for heat dissipation, and controls the heat dissipation controller to enter the OTA upgrade process.

[0050] Furthermore, in the embodiment of the present application, after the OTA upgrade is completed, the OTA main control module sends an exit OTA mode instruction to the thermal management control system. When the thermal management control system receives the exit OTA mode instruction, it exits the current constant speed cooling state and determines whether to continue cooling based on the actual request signal status of the vehicle.

[0051] Furthermore, in one embodiment of the present application, the above-mentioned vehicle thermal management control method also includes: obtaining a network communication type of at least one controller to be upgraded; and controlling a sending method of non-diagnostic message signals according to the network communication type.

[0052] Specifically, the network communication type of at least one controller to be upgraded in the embodiment of the present application can adopt CAN network communication or Ethernet communication. If at least one controller to be upgraded only supports CAN network communication, the underlying software of at least one controller to be upgraded needs to design special processing for the standard protocol stack, that is, when the controller to be upgraded receives the functional addressing or physical addressing diagnostic message service sent by the host computer, the underlying software of at least one controller to be upgraded needs to keep the temperature value signal and the cooling request signal sending normally, and only prohibit other non-diagnostic message signals to ensure that the OTA Master and the thermal management control system can receive them normally; if at least one controller to be upgraded supports Ethernet communication, the temperature value signal and the cooling request signal can be designed as DDS communication protocol or other non-CAN communication protocols, that is, they are not prohibited by the functional addressing or physical addressing diagnostic message service sent by the host computer.

[0053] According to the thermal management control method for a vehicle in an embodiment of the present application, when the thermal management control system is not in a preset cooling execution state, at least one controller to be upgraded of the vehicle is controlled to enter the OTA upgrade process, and after the upgrade is completed, an instruction to exit the OTA mode is sent. When the thermal management control system is in a preset cooling execution state, the current cooling request signal source is identified and the heat dissipation controller is determined. When the heat dissipation controller is not included in at least one controller to be upgraded, at least one controller to be upgraded is directly controlled to enter the OTA upgrade process. In this way, the problem that when the vehicle has actual cooling needs, the thermal management control system cannot receive the cooling request signal or the relevant request signal is forced to be interrupted during the cooling process, causing the controller to be continuously in a high temperature state, affecting the service life of the controller and reducing safety performance is solved. By identifying the controller that needs cooling through the vehicle thermal management demand signal and formulating a corresponding upgrade strategy, it is effectively avoided that after entering the OTA mode, the vehicle is unable to perform cooling and heat dissipation due to the prohibition of the thermal management function signal, thereby improving the service life and safety performance of the vehicle.

[0054] Next, the thermal management control device for a vehicle proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.

[0055] Figure 5 4 is a block diagram of a thermal management control device for a vehicle according to an embodiment of the present application.

[0056] like Figure 5 As shown, the thermal management control device 10 of the vehicle includes: a judgment module 100 , a control module 200 and an identification module 300 .

[0057] The judging module 100 is used to judge whether the thermal management control system is in a preset cooling execution state;

[0058] a control module 200 configured to control at least one controller to be upgraded in the vehicle to enter an OTA upgrade process if the thermal management control system is not in a preset cooling execution state, and to send an exit OTA mode instruction to the thermal management control system after the upgrade of at least one controller to be upgraded is complete; and

[0059] The identification module 300 is used to identify the current cooling request signal source if the thermal management control system is in a preset cooling execution state, determine the heat dissipation controller based on the current cooling request signal source, and directly control at least one controller to be upgraded to enter the OTA upgrade process when the heat dissipation controller is not included in at least one controller to be upgraded.

[0060] Furthermore, in one embodiment of the present application, after determining the heat dissipation controller according to the current cooling request signal source, the identification module 300 further includes: a first judgment unit and a first control unit.

[0061] The first determining unit is configured to determine whether the heat dissipation controller supports dual-partition flashing if at least one controller to be upgraded includes a heat dissipation controller;

[0062] The first control unit is used to directly control at least one controller to be upgraded to enter the OTA upgrade process if the heat dissipation controller supports dual-partition flashing; otherwise, it sends a command to maintain the current cooling state to the thermal management control system, so that the thermal management control system maintains the current water pump flow and flow rate state for heat dissipation, and controls the heat dissipation controller to enter the OTA upgrade process.

[0063] Furthermore, in one embodiment of the present application, before determining whether the thermal management control system is in a preset cooling execution state, the determination module 100 further includes: a second determination unit and a sending unit.

[0064] The second judgment unit is configured to judge whether the OTA upgrade instruction of at least one controller to be upgraded meets the OTA upgrade precondition;

[0065] The sending unit is used to send an instruction to enter the OTA mode to the thermal management control system if the OTA upgrade preconditions are met.

[0066] Furthermore, in one embodiment of the present application, the above-mentioned vehicle thermal management control device 10 further includes: an acquisition unit and a second control unit.

[0067] The acquiring unit is configured to acquire a network communication type of at least one controller to be upgraded;

[0068] The second control unit is used to control the sending mode of the non-diagnostic message signal according to the network communication type.

[0069] Furthermore, in one embodiment of the present application, after sending a command to maintain the current cooling state to the thermal management control system so that the thermal management control system maintains the current water pump flow and flow rate state for heat dissipation and controls the heat dissipation controller to enter the OTA upgrade process, the control unit further includes:

[0070] Sending an exit OTA mode command to the thermal management control system;

[0071] A status signal of at least one controller to be upgraded is received, and when the status signal is in a preset cooling execution state, the at least one controller to be upgraded is controlled to execute a cooling action.

[0072] According to the thermal management control device of the vehicle of the embodiment of the present application, when the thermal management control system is not in the preset cooling execution state, the device controls at least one controller to be upgraded of the vehicle to enter the OTA upgrade process, and sends an exit OTA mode instruction after the upgrade is completed. When the thermal management control system is in the preset cooling execution state, the device identifies the current cooling request signal source and determines the heat dissipation controller, and when at least one controller to be upgraded does not include a heat dissipation controller, the device directly controls at least one controller to be upgraded to enter the OTA upgrade process. In this way, the problem that when the vehicle has actual cooling demand, the thermal management control system cannot receive the cooling request signal or the relevant request signal is forced to be interrupted during the cooling process, causing the controller to be continuously in a high temperature state, affecting the service life of the controller and reducing safety performance is solved. By identifying the controller that needs cooling through the vehicle thermal management demand signal and formulating a corresponding upgrade strategy, the vehicle is effectively prevented from being unable to perform cooling and heat dissipation after entering the OTA mode due to the prohibition of the thermal management function signal, thereby improving the service life and safety performance of the vehicle.
