[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] The unlocking method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. The vehicle includes a battery management device 10, a vehicle controller 20 and a body controller 30, and the battery management device 10, the vehicle controller 20 and the body controller 30 are communicatively connected. The battery management device 10 is a BMS (Battery Management System), the body controller 30 is a BCM (body control module), and the vehicle controller 20 is a VCU (Vehicle Control Unit).

[0041] In an exemplary embodiment, Figure 2 As shown, an unlocking method is provided, which is applied to Figure 1 The battery management device 10 in FIG. 1 is taken as an example to illustrate, including the following steps 201 to 203.

[0042] in:

[0043] Step 201, obtaining battery parameters of a battery in a vehicle, and determining a state of the battery according to the battery parameters.

[0044] Among them, the battery parameters may include the temperature of the battery cell or the voltage, current and other data of the battery cell, and the battery parameters of the vehicle in various working states, such as running, stopping, charging or collision and other states, can be obtained. The battery state may include a normal state and an abnormal state. When the temperature of the battery cell exceeds a preset threshold, or the temperature difference or voltage difference between the battery cells exceeds a preset difference threshold, it can be determined that the battery is in an abnormal state, that is, the battery may have a risk of thermal runaway. Among them, the preset threshold and the preset difference threshold can be determined according to the parameters of the battery cell.

[0045] Step 202: If the battery state is an abnormal state, determine a target unlocking control mechanism according to the type of the battery state.

[0046] If it is determined that the battery is in an abnormal state, the type of the battery state can be further determined according to the degree of abnormality. Different types can correspond to different unlocking control mechanisms. The target unlocking control mechanism is the unlocking control mechanism corresponding to the type of the current battery state. The unlocking control mechanism may include a vehicle controller and a body controller of the vehicle.

[0047] Step 203: Control the vehicle to unlock through the target unlocking control mechanism.

[0048] The vehicle is controlled to automatically unlock the doors through the target unlocking control mechanism, so as to realize automatic unlocking in case of battery abnormality.

[0049] In the above embodiment, first, the battery parameters of the battery in the vehicle are obtained, and the battery state is determined according to the battery parameters, and then a judgment is made. If the battery state is abnormal, the target unlocking control mechanism is determined according to the type of battery state, and finally, the vehicle is unlocked by the target unlocking control mechanism. In this way, when it is determined that the battery of the vehicle is in an abnormal state, the target unlocking control mechanism is determined, and the vehicle can be unlocked according to the target unlocking control mechanism, and the door can be unlocked automatically in the case of abnormal battery without manual opening, thereby improving the safety of electric vehicles.

[0050] In one embodiment, the target unlocking control mechanism is determined according to the type of battery status, including two cases.

[0051] In the first case, if the battery is in the first state, the vehicle controller is used as the target unlocking control mechanism, and the vehicle controller is used to control the body controller to unlock the vehicle.

[0052] Among them, the first state can be a high temperature state, at this time, the battery cell temperature may exceed the first temperature threshold T1, the temperature difference between the battery cells exceeds the first temperature difference threshold, or the pressure difference between the battery cells exceeds the first pressure difference threshold, that is, the battery may be at risk of thermal runaway. Therefore, the vehicle controller is used as the target unlocking controller, and the vehicle controller controls the vehicle to unlock. For example, when the battery management device detects that the battery is in a high temperature state, it sends an alarm message to the vehicle controller for early warning. After receiving the alarm message, the vehicle controller sends an unlocking command to control the body controller to automatically unlock the door. Optionally, the unlocking information can be fed back to the vehicle's instrument display or synchronized to the application of the owner's terminal device at the same time.

[0053] Optionally, when the vehicle controller is used as the target unlocking control mechanism, a cooling instruction is sent to the vehicle controller, and the cooling instruction is used to instruct the vehicle controller to control the vehicle compressor to cool the battery.

[0054] When the target unlocking control mechanism is determined to unlock the vehicle, the battery management device sends a cooling instruction to the vehicle controller. After receiving the cooling instruction, the vehicle controller cools the battery. Figure 3 As shown, the vehicle controller controls the vehicle compressor to allocate all cooling functions to the power battery, turns off the cooling function of the vehicle passenger compartment, and adjusts the water inlet temperature of the liquid cooling plate from 22°C to 15°C. During the cooling process, the battery temperature can be continuously monitored. If the battery temperature drops and returns to normal temperature, the warning is cancelled. If the battery temperature continues to rise, the battery management device sends a power-off command to request the high-voltage main relay to turn off, so that the vehicle is powered off to avoid further increase in battery temperature that may cause battery smoke or fire.

[0055] In the second case, if the battery is in the second state, the vehicle body controller is used as the target unlocking control mechanism.

[0056] Among them, the battery temperature corresponding to the first state is lower than the battery temperature corresponding to the second state. The second state may be a battery smoking or fire state, at which time the battery cell temperature may exceed the second temperature threshold T2, the temperature difference between the battery cells exceeds the second temperature difference threshold, or the pressure difference between the battery cells exceeds the second pressure difference threshold, that is, the battery has thermal runaway, which may threaten the safety of the passenger compartment. Optionally, T2>T1, the second temperature difference threshold is greater than the first temperature difference threshold, and the second pressure difference threshold is greater than the first pressure difference threshold. Therefore, at this time, the body controller is used as the target unlocking control mechanism, and optionally, the battery management device directly sends instructions to the body controller through the CAN bus to unlock the door.

[0057] In the above embodiment, the target unlocking control mechanism is determined according to the different types of battery conditions, so that different unlocking control mechanisms can be determined according to the severity of the battery conditions. The unlocking method is more flexible. When the battery is in the second state, that is, the battery is smoking or on fire, the body controller is directly controlled to unlock without going through the vehicle controller. The unlocking can be performed faster and more efficiently, which is convenient for passengers to evacuate or rescue in time.

[0058] In an embodiment of the present application, vehicle unlocking is controlled by a target unlocking control mechanism, including sending an unlocking instruction to the body controller when the body controller is used as the target unlocking control mechanism, the unlocking instruction is used to instruct the body controller to unlock the vehicle, wherein the priority of the unlocking instruction is greater than a preset priority threshold.

[0059] Optionally, in order to ensure that the vehicle is unlocked as soon as possible when the battery is smoking or on fire, so as to facilitate the evacuation of passengers in the vehicle as soon as possible, the battery management device sends an unlocking command to the body controller to control the body controller to unlock. Among them, the preset priority threshold can be the highest priority in the body controller, and the priority of the unlocking command is greater than the preset priority threshold, that is, the unlocking command can be the highest priority command in the body controller, so that when the body controller receives the unlocking command, it can process the response in the first time and unlock the vehicle.

[0060] In one embodiment, the method further includes sending a power-off instruction to the body controller when the body controller is used as the target unlocking control mechanism, where the power-off instruction is used to instruct the body controller to power off the vehicle.

[0061] Optionally, after the battery management device sends an unlock command to the body controller, it sends a power-off command to turn off the high-voltage main relay to prevent the battery temperature from further increasing.

[0062] In one embodiment, when the battery is in the second state, timely rescue can be performed for the people in the vehicle by exchanging information with the server, such as Figure 4 As shown, the steps include:

[0063] Step 401, obtaining a first detection result of a life detection device of the vehicle and a second detection result of a seat gravity detection device.

[0064] Generally, when the vehicle is unlocked, passengers can get out of the vehicle through the door. However, in extreme cases, especially with hidden door handles, such as when a vehicle crashes and causes passengers to be injured or unconscious and unable to evacuate on their own, external rescuers can open the automatically unlocked door to rescue the passengers. Therefore, the battery management device can send rescue information to the server to facilitate timely rescue of the people in the vehicle. If the vehicle controller is the target unlocking execution structure, the vehicle controller can also send rescue information to the server.

[0065] The life detection device may include a life detector, which can determine whether there is life in the vehicle by searching for infrared radiation, breathing or heartbeat signals, and obtain a first detection result. The seat gravity detection device may be set in the vehicle seat to detect whether there is a trapped person on the seat and determine the position of the trapped person, and obtain a second detection result.

[0066] Step 402, sending the first detection result and the second detection result to the server, so that the server can perform rescue processing according to the first detection result and the second detection result.

[0067] The rescue process includes sending an alarm signal. The first detection result and the second detection result are sent to the server, and the server determines whether there are people in need of rescue in the vehicle based on the first detection result and the second detection result, and remotely connects to the voice system in the vehicle for a call, and performs alarm processing based on the first detection result, the second detection result and the call status.

[0068] In an embodiment of the present application, the flowchart of the unlocking method can be as follows: Figure 5 As shown. The battery management device detects the internal state of the battery. When the battery is in a high temperature state, the target unlocking actuator is the vehicle controller, and the vehicle controller sends instructions to control the body controller to unlock. When the battery is in a smoking or fire state, the target unlocking actuator is the body controller, and the battery management device directly sends an unlocking instruction to the body controller to unlock. At the same time, when the battery is in a smoking or fire state, the battery management device sends an early warning message to the server. After receiving the early warning message, the server determines the location of the vehicle, and then remotely connects to the voice system in the vehicle for a call, and obtains the first detection result of the life detection device and the second detection result of the seat gravity detection device. If the first and second detection results indicate that there are no passengers in the car, and no one responds during the voice call, the server notifies the service personnel near the vehicle and calls the local fire alarm for alarm processing. If the first and second detection results indicate that there are passengers in the car and someone responds during the voice call, the server notifies the driver of the current battery status through voice, and requires the driver to pull over and evacuate immediately, and calls the local fire alarm for alarm processing. If the first detection result and the second detection result indicate that there are passengers in the vehicle and no one responds during the voice communication, the server notifies the service personnel near the vehicle and calls the local fire alarm and emergency number for alarm processing.

[0069] In the above embodiment, the first detection result and the second detection result are sent to the server, and the server performs alarm processing according to the real-time situation of the vehicle to ensure timely rescue of the people in the vehicle.

[0070] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0071] An embodiment of the present application also provides an unlocking system for implementing the unlocking method involved above. The implementation scheme of the problem solved by the system is similar to the implementation scheme recorded in the above method. Therefore, the specific limitations in one or more unlocking system embodiments provided below can refer to the limitations on the unlocking method above and will not be repeated here.

[0073] The battery management device is used to obtain the battery parameters of the battery in the vehicle and determine the battery status based on the battery parameters.

[0076] In one embodiment, the power supply of the battery management device and the vehicle body controller includes a first power supply and a second power supply.

[0077] The first power supply can be powered by DC / DC (direct current to direct current) conversion, that is, the battery is powered after DC / DC conversion, and the second power supply can be a 12V backup battery. In this way, when the battery fails and the power is cut off, and the first power supply cannot supply power, the second power supply can be used to power the battery management device and the body controller, thereby ensuring the normal operation of the communication and door unlocking action in the vehicle. Figure 6As shown, when the power battery is in normal state, the DC / DC can be used to power the battery management device and the body controller, and the 12V backup battery can be charged at the same time. When the power battery is abnormal, the 12V backup battery will power the battery management device and the body controller. Optionally, the battery management device and the communication harness in the vehicle can be protected with fire-resistant and high-temperature resistant materials to avoid malfunction in high temperature environments.

[0078] In one embodiment, the unlocking system further includes a life detection device, which is used to detect the status of a person inside the vehicle, and the power supply of the life detection device includes a second power supply and a third power supply.

[0079] Optionally, the power supply of the life detection equipment also includes a third power supply, which can be a solar power generation and energy storage module. The life detector is normally powered by the second power supply. If the second power supply fails, the life detector is powered by the third power supply, further ensuring that the normal operation of the life detector is not affected under any circumstances. Similarly, the seat gravity detection equipment can also adopt the same dual power supply solution to improve stability and ensure that it can detect in time whether there are people who need rescue. Figure 7 As shown, it is a structural block diagram of the unlocking system.

[0080] In one embodiment, the unlocking system further includes a seat gravity detection device, which is used to detect the position of a person inside the vehicle.

[0081] Through the seat gravity detection equipment at different seat positions, it is possible to detect whether there are passengers in different seat positions, thereby determining the position of people inside the vehicle and facilitating rescue by rescue personnel.

[0082] The above unlocking system can be implemented in whole or in part by software, hardware or a combination thereof. It can be embedded in or independent of the processor in the computer device in the form of hardware, or it can be stored in the memory of the computer device in the form of software, so that the processor can call and execute the operations corresponding to the above modules.
