[0031] Specifically, the modules and devices involved in the thermal runaway early warning control system in the embodiments of the present application include a power domain controller 100, a vehicle body domain controller 200, and various execution devices (at least including a battery 310 and a vehicle body device 320). Among them, the power domain controller 100 and the vehicle body domain controller 200 both belong to the domain controller, integrate multiple related function ECUs, and realize the cooperative management and control of each ECU. The power domain controller 100 is mainly responsible for controlling the execution devices related to the power system of the vehicle (such as the battery 310), and the vehicle body domain controller 200 is mainly responsible for controlling the vehicle body device 320 arranged on the vehicle body.

[0032] According to the responsibilities of different modules inside the power domain controller 100 and the vehicle body domain controller 200, they are divided into service layers or application layers. In the power domain controller 100, at least the battery service module 110 is arranged in the service layer, and the power application module 120 is arranged in the application layer; in the vehicle body domain controller 200, at least the vehicle body service module 210 is arranged in the service layer, and the vehicle body application module 220 is arranged in the application layer; and each execution device belongs to the sensor execution layer. It needs to be explained that the sensor execution layer corresponds to the service layer or the application layer, and not to the domain controller. In addition, for the application layer, the service layer and the sensor execution layer, in order to facilitate observation, they are directly marked in the above-mentioned Figure 1 , and no additional marking is performed.

[0033] Based on the architecture of the execution device, the service layer module and the application layer module, the service is generated by encapsulating the service layer module to form a standardized interface, and the communication and cooperation between the services, the modules and each device are realized. In the above-mentioned architecture, at least two sets of control links are formed, one of which is based on the battery service module 110, and the other of which is based on the vehicle body service module 210.

[0034] The embodiments of the present application also provide a thermal runaway early warning control method based on SOA service, Figure 2 is an optional flowchart of the thermal runaway early warning control method based on SOA service, Figure 2 The method in the above-mentioned may include but is not limited to steps S101 to S104.

[0035] Step S101, monitoring the running state of the target vehicle battery 310 through the battery service module 110, determining the running state of the battery 310, and feeding back the running state of the battery 310 to the power application module 120 and the vehicle body application module 220 according to a preset period; Step S102, through the battery service module 110, in response to receiving the first early warning signal feedback by the battery 310, generating a thermal runaway early warning service according to the first early warning signal, and feeding back a second early warning signal and a third early warning signal to the power application module 120 and the vehicle body application module 220 respectively through the thermal runaway early warning service; Step S103, through the power application module 120, in response to receiving the second early warning signal, calling the battery control service of the battery service module 110 to control the battery 310 to power off; Step S104, through the vehicle body application module 220, in response to receiving the third early warning signal, calling the vehicle body control service of the vehicle body service module 210 to control the vehicle body device 320 to open or close.

[0036] For the control link described in the above embodiment, specifically, the battery service module 110 continuously monitors the running status of the battery 310 after the vehicle starts, determines whether the running state of the battery 310 is normal, and the running state is also periodically fed back to the power application module 120 and the vehicle body application module 220 according to a preset period, for example, every 100ms, etc., through the service configured on the battery service module 110, so that the power application module 120 and the vehicle body application module 220 determine the running state of the battery 310, thereby determining whether to trigger the related application of the thermal runaway early warning control.

[0037] When the battery 310 occurs a thermal runaway accident, the signal feedback by the battery 310 is defined as the first early warning signal, and when the battery service module 110 receives the signal, the battery service module 110 can convert the first early warning signal into a corresponding thermal runaway early warning service, and notify the power application module 120 and the vehicle body application module through the service, and the signals used for notification feedback are defined as the second early warning signal and the third early warning signal respectively. On the side of the power application module 120, the module starts the thermal runaway early warning related application through the second early warning signal, calls the battery control service of the battery service module 110, sends a control instruction to the battery 310 in the sensor actuator layer, controls the battery 310 to power off, forms a control link connected in sequence among the battery 310, the battery service module 110 and the power application module 120, and stops the possibility of further development of the thermal runaway problem from the source by powering off the battery, thereby improving the safety. On the side of the vehicle body application module 220, the module starts the thermal runaway early warning related application through the third early warning signal, calls the vehicle body control service of the vehicle body service module 210, controls the actuator on the vehicle body to open or close, for example, the vehicle door 340 and the alarm lamp are converted to the state in the dangerous accident scene, thereby further ensuring the safety of the passengers on the vehicle.

[0038] In this control process, the propagation of signals and data, and the execution of control operations, are all around the various service implementations encapsulated by the service layer, avoiding the need to control each ECU point by point, thereby improving the stability of the thermal runaway early warning system in special dangerous scenarios, ensuring its rapid response, and improving the safety of the people on the vehicle.

[0039] The embodiments of the present application set up a power domain controller 100, a vehicle body domain controller 200 and a sensor execution layer. In the power domain controller 100, the battery service module 110 is set in the service layer, and the power application module 120 is set in the application layer. In the vehicle body domain controller 200, the vehicle body service module 210 is set in the service layer, and the vehicle body application module 220 is set in the application layer. The application layer controls each device of the sensor execution layer by calling the services generated by the service layer. Compared with point-to-point communication between controllers, by integrating service components in the service layer, using services with unique and independent identifiers that do not affect each other, and being able to complete their own publishing, subscription to other services and communication with other services, the problem of high complexity of point-to-point communication matrix is avoided, and the flexibility and expandability of the coordination work between controllers and the stability of the vehicle thermal runaway early warning function are improved.

[0040] In some embodiments, with reference to Figure 3 The power domain controller 100 further includes a cooling water pump service module 130 set in the service layer, and the cooling water pump 330 of the target vehicle is set in the sensor execution layer. The power application module 120 is further configured to control the cooling water pump 330 to start according to the thermal runaway early warning service through the cooling water pump service module 130, so as to cool the battery 310.

[0041] In addition, the method further includes: through the power application module 120, in response to receiving the second early warning signal, calling the cooling water pump control service of the cooling water pump service module 130 to control the cooling water pump 330 to cool the battery 310.

[0042] On the side of the power application module 120 in the present embodiment, the power application module 120 can also call the cooling water pump control service provided by the cooling water pump service module 130 in the service layer after starting the thermal runaway early warning related application, and send control instructions to the cooling water pump 330 in the sensor execution layer. The cooling water pump 330 is a water pump specially used for battery cooling, which can take away the heat in the battery 310 through heat exchange of the cooling liquid, realize cooling of the battery 310, and form a control link connected in sequence between the cooling water pump 330, the cooling water pump service module 130 and the power application module 120. By cooling the battery 310, the possibility of further development of the thermal runaway problem is reduced, and the safety is improved.

[0043] In some embodiments, with reference toFigure 3 The vehicle body service module 210 includes a vehicle door service module 230, and the vehicle body device 320 includes vehicle doors 340. The vehicle body application module 220 is further configured to control the vehicle doors 340 to be unlocked by the vehicle door service module 230 according to the thermal runaway early warning service.

[0044] In addition, the method further includes: in response to receiving the third early warning signal, calling, by the vehicle body application module 220, a vehicle door control service of the vehicle door service module 230 to control the vehicle doors 340 to be unlocked.

[0045] On the side of the vehicle body application module 220 in the embodiment, after starting the thermal runaway early warning related application, the vehicle body application module 220 calls a vehicle door control service provided by the service layer vehicle door service module 230 to send a control instruction to the sensor actuator layer vehicle doors 340, the vehicle doors 340 including all the vehicle doors on the vehicle, and controls the vehicle doors 340 to be switched to an unlocked state, forming a control link connected in sequence between the vehicle doors 340, the vehicle door service module 230 and the vehicle body application module 220. By unlocking the vehicle doors 340, it is ensured that there is a safe space for the people on the vehicle to avoid danger when the thermal runaway problem occurs, and the safety is improved.

[0046] In some embodiments, with reference to Figure 3 The vehicle body service module 210 includes a hazard warning light service module 240, and the vehicle body device 320 includes hazard warning lights 350. The vehicle body application module 220 is further configured to control the hazard warning lights 350 to flash by the hazard warning light service module 240 according to the thermal runaway early warning service.

[0047] In addition, the method further includes: in response to receiving the third early warning signal, calling, by the vehicle body application module 220, a hazard warning light control service of the hazard warning light service module 240 to control the hazard warning lights 350 to flash.

[0048] The hazard warning light, also known as the double flash light, is a light device on the vehicle for transmitting emergency or abnormal state signals, and its core function is to remind surrounding vehicles or pedestrians to pay attention to the special situation of the vehicle. In the embodiment, it is applicable to be triggered when thermal runaway occurs.

[0049] On the side of the vehicle body application module 220 in the embodiment, after the vehicle body application module 220 starts the hot crash pre-warning related application, the vehicle body application module 220 calls the alarm lamp control service provided by the service layer alarm lamp service module 240, sends a control instruction to the danger alarm lamp 350 of the sensor executor layer, controls the danger alarm lamp 350 to flash, and forms a control link connected in sequence among the danger alarm lamp 350, the alarm lamp service module 240, and the vehicle body application module 220. By controlling the danger alarm lamp 350 to flash, the emergency state of the hot crash is notified to the vehicles and pedestrians nearby, the passing vehicles and pedestrians are prevented from being involved in the accident, and the safety is improved.

[0050] In some embodiments, referring to Figure 3 , the system further includes an instrument 500, and the battery service module 110 is further configured to notify the instrument 500 of the hot crash pre-warning service, and control the instrument 500 to issue an audible and light alarm.

[0051] The instrument is the instrument panel of the vehicle, which is usually arranged in front of the driver's seat, and can reflect the working conditions of various systems on the vehicle through various indicator lights, pointers, and digital display screens, helping the driver to understand the running state of the vehicle.

[0052] In the embodiment, the instrument is included as one of the devices of the hot crash pre-warning system. When the battery service module 110 monitors the running state of the battery 310, the battery service module 110 also feeds back the running state to the instrument 500 through the service configured thereon, so that the driver can also intuitively observe the running state of the battery 310 during driving.

[0053] During the hot crash pre-warning, the instrument 500 can not need to be controlled through the vehicle body application module 220 or the power application module 120, because it does not belong to the devices related to the power system or the vehicle body. When the battery service module 110 feeds back the pre-warning signal to the vehicle body application module 220 and the power application module 120, the fourth pre-warning signal is also fed back to the instrument 500 through the hot crash pre-warning service, so that the instrument 500 can also know that the battery hot crash occurs. At this time, the instrument 500 can issue an audible and light alarm according to the fourth pre-warning signal, so as to timely notify the driver of the battery hot crash problem in the most eye-catching position in front of the driver, so as to urge the driver to take precautions and improve the safety.

[0054] In some embodiments, referring to Figure 3 , the system further includes a first gateway 410 and a second gateway 420, the first gateway 410 is used to provide an Ethernet data transmission interactive channel for the instrument 500 and the battery service module 110, and the second gateway 420 is used to provide an Ethernet data transmission interactive channel for the vehicle body application module 220 and the battery service module 110.

[0055] For the architecture of the thermal runaway early warning control system based on the SOA service of the embodiment of the application, in combination with the above embodiment, the module devices involved can be divided into four parts, including the power domain controller 100, the vehicle body domain controller 200, the instrument 500 and the actuator devices (such as the battery 310 and the vehicle door 340, etc.). It can be understood that this is divided according to the module function positioning on the vehicle, and the different parts are coupled with each other and transmit data to each other, but the devices of the different parts are not necessarily provided with direct line connections on the physical layer. Therefore, the embodiment further provides a gateway, specifically a first gateway 410 and a second gateway 420, which are both used to provide an Ethernet data transmission interaction channel for the modules or devices that do not have direct line connections; wherein the first gateway 410 is arranged between the instrument 500 and the battery service module 110, and the second gateway 420 is arranged between the vehicle body application module 220 (arranged in the vehicle body domain controller 200) and the battery service module 110 (located in the power domain controller 100). Thus, under the support of the first gateway 410 and the second gateway 420, the service calling, signal transmission and instruction transmission of the above embodiment are realized.

[0056] Next, the scheme of the embodiment of the application will be described and explained in detail in combination with specific application examples: In the embodiment of the application, a thermal runaway early warning control method and system based on SOA service are provided, which are applied to a vehicle. Referring to Figure 3 The system includes an instrument 500, a first gateway 410, a second gateway 420, a power domain controller 100, a vehicle body domain controller 200 and a sensor actuator layer, the sensor actuator layer including a battery 310, a cooling water pump 330, a vehicle door 340 and a hazard warning light 350; wherein the power domain controller 100 and the vehicle body domain controller 200 both have modules arranged in the service layer and the application layer, the power domain controller 100 includes a battery service module 110 and a cooling water pump service module 130 arranged in the service layer, and a power application module arranged in the application layer, the vehicle body domain controller 200 includes a warning light service module 240 and a vehicle door service module 230 arranged in the service layer, and a vehicle body application module 220 arranged in the application layer.

[0057] Based on the above architecture, the battery service module 110 monitors the running state of the battery 310 and periodically feeds back the running state of the battery 310 to the instrument 500, the power application module 120 and the vehicle body application module 220. When the battery thermal runaway occurs, the battery service module 110 receives the first early warning signal fed back by the battery 310, generates a thermal runaway early warning service according to the first early warning signal through the battery service module 110, further feeds back a second early warning signal to the power application module 120 through the thermal runaway early warning service, feeds back a third early warning signal to the vehicle body application module 220 through the Ethernet data transmission interactive channel provided by the second gateway 420, feeds back a fourth early warning signal to the instrument 500 through the Ethernet data transmission interactive channel provided by the first gateway 410, and realizes the notification of the thermal runaway problem to other modules through the service.

[0058] After receiving the second early warning signal, the power application module 120 calls the battery control service of the battery service module 110, generates a corresponding control instruction to control the battery 310 to power off, and calls the cooling water pump control service of the cooling main pump service module, generates a corresponding control instruction to control the cooling water pump 330 to start and cool the battery 310.
