Description

[Technical field]

[0001] The present application relates to the technical field of vehicle control, and in particular to a charging electronic lock unlocking control method, device, vehicle and readable medium. [Background technology]

[0002] As the market share of new energy vehicles increases, the problem of charging new energy vehicles is becoming more and more prominent. The requirements for charging guns before, during and after charging are more specific. According to relevant regulations, it is required to "provide a locking mechanism to ensure the reliable connection between the vehicle plug and the power plug. If the rated current of the power supply equipment is less than or equal to 16A, this function is optional, and if it is greater than 16A, this function is mandatory";

[0003] Regarding the unlocking and locking control of the charging electronic lock, the following technical means can be specifically adopted in the relevant technology: after the vehicle recognizes that the charging gun is inserted, the charging electronic lock is locked. After charging is completed, the user presses and holds the unlock button of the charging gun to disconnect it and then pull out the gun. The above method is not convenient for users to pull out the gun at any time, and cannot completely avoid the risks of arcing during the high current gun pulling process. And when the vehicle is fully charged, the user needs to go to the site to unlock and pull out the gun. Furthermore, the charging gun cannot automatically unlock the charging gun. At the same time, when the user unlocks the vehicle during the charging process, the charging current decreases. When the vehicle is locked again, the charging current is not restored, resulting in a decrease in charging power and an increase in charging time.

[0004] In summary, in the related technologies, charging of new energy vehicles has brought many inconveniences to users. [Summary of the invention]

[0049] In order to better understand the technical solution of the embodiment of the present invention, the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0050] It should be clear that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present invention.

[0051] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the embodiments of the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0052] First, the various systems involved in this application are introduced:

[0053] The BMS (Battery Management System) in this application is used to manage the charging and discharging of the battery to keep the battery in an optimal state. The BCM (Body control module) is used to implement discrete control functions and control many electrical appliances. The specific functions of the body control module include: electric door and window control, central door lock control, remote anti-theft, lighting system control, electric rearview mirror heating control, instrument backlight adjustment, power distribution, etc. OBC (On board charger) is generally a low-power charger, which is divided into on-board wired charging and on-board wireless charging. VCU (Vehicle control unit) is the core of the entire control system as the central control unit of new energy vehicles. VCU collects motor and battery status, and also collects accelerator pedal signals, brake pedal signals, actuators and sensor signals through its own IO port.

[0054] Please refer to Figure 1 , Figure 1 A flow chart of a charging electronic lock unlocking control method provided in an embodiment of the present application is applied to a vehicle equipped with a system including a BMS and a BCM, specifically comprising the following steps:

[0055] S101: In response to a preset condition, the BMS sends a charging electronic lock action request to the BCM;

[0056] S102: the BCM controls the charging electronic lock to perform an unlocking or locking action corresponding to the electronic lock action request in response to the electronic lock action request;

[0057] Through S101 to S102, the user can easily draw the gun at any time, avoiding the risk of arcing during high current drawing of the gun. At the same time, it solves the technical problem of reduced charging power when unlocking and locking the vehicle during the charging process.

[0058] Please refer to Figure 2 , Figure 2 A flowchart of another charging electronic lock unlocking control method provided in an embodiment of the present application specifically includes the following steps:

[0059] S201: In response to a charging electronic lock unlocking condition, the BMS sends a charging electronic lock unlocking request to the BCM;

[0060] That is, in the embodiment provided in the present application, the preset condition includes: a charging electronic lock unlocking condition, and the charging electronic lock action request includes: a charging electronic lock unlocking request;

[0061] In the first scenario, the unlocking condition of the charging electronic lock includes: after the user triggers the direct gun drawing function, the charging current is less than the first preset value;

[0062] Specifically, after the user selects the direct gun drawing function on the multimedia, the BMS receives an instruction to allow direct gun drawing, which is more specific in combination with the requirements of the charging gun before, during and after charging. According to the requirements of 5.2.2.3 in GB / T 18487.12015: Provide a locking mechanism to ensure the reliable connection of the vehicle plug and the power plug. The rated current of the power supply equipment is less than or equal to 16A. This function is optional, and greater than 16A. This function is mandatory. Therefore, when the user selects the direct gun drawing function, the BMS responds to the direct gun drawing instruction and controls the charging current to be less than or equal to 16A. Here, 16A is the corresponding first preset value. When the charging current is less than or equal to 16A, the charging electronic lock unlocking condition is met;

[0063] In the second scenario, if the BCM receives a door lock unlocking command and the charging current is less than the first preset value, the charging electronic lock unlocking condition is met;

[0064] It should also be noted that the door lock unlocking command can be triggered by the vehicle remote control, PE switch, central control switch, remote unlocking, and Bluetooth unlocking. When the user triggers the door lock unlocking command by any of the vehicle remote control, PE switch, central control switch, remote unlocking, and Bluetooth unlocking, it is considered to have triggered the door lock unlocking command;

[0065] Similarly, when the door lock unlocking command is triggered, the BMS controls the charging current to be less than or equal to 16A. When the charging current is less than or equal to 16A, the charging electronic lock unlocking condition is met;

[0066] In the third scenario, the state of charge is 100%. Here, the state of charge is SOC (State of Charge). The state of charge is used to characterize the energy storage in the energy storage element of the energy vehicle. SOC of 100% represents charging completion. That is to say, when the BMS detects that charging is completed, the charging electronic lock unlocking condition is met.

[0067] In the fourth scenario, during normal charging, in response to a charging electronic lock unlocking command, the power gear is in the OFF gear, the BCM receives a door lock unlocking command, and the charging current is less than a first preset value, that is, the charging electronic lock unlocking condition is met;

[0068] It is worth noting that in this embodiment, the charging electronic lock unlocking instruction can be triggered by long pressing the charging electronic lock unlocking button, which is located on the charging gun. Exemplarily, when the user presses the charging electronic lock unlocking button for more than 2 seconds, the charging electronic lock unlocking instruction is automatically triggered. At this time, if the power gear is in the OFF gear and the BCM receives the door lock unlocking instruction triggered by the user, the BMS controls the charging current to be less than or equal to 16A. When the charging current is less than or equal to 16A, the charging electronic lock unlocking condition is met;

[0069] In combination with the above, the method in which the user triggers the door lock unlocking command has been mentioned above and will not be repeated here.

[0070] In the fifth scenario, during normal charging, in response to a charging electronic lock unlocking instruction, the power gear is in a non-OFF gear position, and the charging current is less than a first preset value;

[0071] In combination with the above, the method in which the user triggers the unlocking command of the charging electronic lock has been mentioned above and will not be repeated here.

[0072] When the user triggers the unlock command of the charging electronic lock, the power gear position is determined. If the power gear is not in the OFF position, the BMS controls the charging current to be less than or equal to 16A. When the charging current is less than or equal to 16A, the unlock condition of the charging electronic lock is met;

[0073] S202: The BCM controls the charging electronic lock to unlock in response to the charging electronic lock unlocking request;

[0074] In step S201, when the charging electronic lock unlocking condition is met, the BMS sends a charging electronic lock unlocking request to the BCM, and the BCM responds to the charging electronic lock unlocking request and controls the charging electronic lock to unlock;

[0075] Through the aforementioned embodiments, the user can draw the gun at any time, which improves the user experience.

[0076] Please refer to Figure 3 , Figure 3 Another flow chart of a charging electronic lock unlocking control method provided in an embodiment of the present application specifically includes the following steps:

[0077] S301: In response to a charging electronic lock locking condition, the BMS sends a charging electronic lock locking request to the BCM;

[0078] In some embodiments, the CC resistance meets the locking condition, the user has not triggered the door lock unlocking command, the state of charge is not 100%, and the user has not triggered the charging electronic lock unlocking command, which satisfies the charging electronic lock locking condition;

[0079] It should be noted that the CC resistance value can determine whether the vehicle plug and the vehicle socket are fully connected. When the CC resistance value meets the locking adjustment, the user does not issue an unlocking command in any way, and the SOC is not 100%;

[0080] The unlocking instructions here include door lock unlocking instructions and charging electronic lock unlocking instructions. Please refer to the above for the door lock unlocking instructions and charging electronic lock unlocking instructions, which will not be repeated here.

[0081] That is to say, when the CC resistance meets the locking condition, the vehicle's energy storage element is not fully charged, and the user has not issued a door lock unlocking command and a charging electronic lock unlocking command, the charging electronic lock locking condition is met;

[0082] In some further embodiments, after the BMS sends a request to unlock the charging electronic lock, the CC resistance meets the locking condition after a preset time has passed;

[0083] That is, when the user triggers the BMS to send a charging electronic lock unlocking request by any of the aforementioned steps S201, illustratively, after 60 seconds, if the CC resistance meets the locking condition, the BMS is triggered to send a charging electronic lock unlocking request;

[0084] This scenario is mainly aimed at the situation that when the charging electronic lock is unlocked, the charging current decreases. When the vehicle is locked, the charging current has not been restored and the charging efficiency decreases. In this way, when it is detected that the CC resistance meets the locking condition, the charging current has been restored, which improves the charging efficiency.

[0085] In other embodiments, during the charging process, if the BCM receives a door lock lock command, the charging electronic lock lock condition is met;

[0086] It should be noted that user-triggered locking commands include but are not limited to: vehicle remote control, PE switch, central control switch trigger, remote unlocking, Bluetooth unlocking trigger, which are not limited here;

[0087] S302: The BCM controls the charging electronic lock to lock in response to the charging electronic lock lock request.

[0088] Through step S301 , the BMS sends a charging electronic lock lock request to the BCM. When the BCM receives the charging electronic lock lock request, it controls the charging electronic lock to lock.

[0089] On the basis of the above-mentioned embodiment, in order to enable the OBC, VCU, BMS, and BCM to work normally, in response to a preset condition, before the step of the BMS sending a charging electronic lock action request to the BCM, the method further includes:

[0090] When the user plugs in the gun, the CC resistance or CP duty cycle rising edge changes to wake up the OBC and initialize it. The OBC wakes up the VCU, BMS, and BCM.

[0091] Furthermore, when the user inserts the charging gun, the vehicle wakes up the OBC through the rising edge of the CC resistance and the CP (control pilot function) duty cycle. After the OBC is woken up, it is initialized. If the initialization is not completed within the preset time, the feedback is that the initialization failed.

[0092] When OBC is initialized, OBC wakes up VCU, BMS, and BCM through CAN messages, and VCU, BMS, and BCM are initialized. If VCU, BMS, and BCM are not initialized within the preset time, initialization failure is fed back. When VCU, BMS, and BCM are initialized, VCU enters the identification mode and identifies whether AC charging is performed. If AC charging is not performed within the preset time, external AC fault is fed back and charging is terminated.

[0093] That is, the VCU identifies the external AC charging state. If the VCU identifies that the AC charging process has not been entered within a preset time range, the charging is terminated;

[0094] In this way, the VCU, BMS, and BCM are awakened and the charging status is identified.

[0095] Please refer to Figure 4 , Figure 4 A structural diagram of a charging electronic lock unlocking control device provided in an embodiment of the present application is applied to a vehicle, wherein the vehicle is equipped with a system including a BMS and a BCM, including:

[0096] Response module: used for responding to a preset condition, the BMS sends a charging electronic lock action request to the BCM;
