[0030] Figure 1 is a flow chart of a high-voltage safety fault processing method according to an embodiment of the application, as shown in the figure, the method comprises the following steps: Figure 1

[0031] Step S102, in response to monitoring that the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, controlling the driving system of the vehicle to be in a stop working state.

[0032] Among them, the high-voltage safety fault can include but not limited to high-voltage interlock fault, high-voltage insulation fault, high-voltage collision fault, etc., the preset duration can be understood as the advance preset, can be considered that the duration of the high-voltage safety fault time is long enough to affect the safety of passengers, for example, can be set to 2 seconds, its specific value can be changed according to the actual demand, the present application does not make limited, stop working state can be understood as the system in the vehicle stops running, the state of the vehicle no longer driving.

[0033] Specifically, controlling the driving system of the vehicle to be in a stop working state can include but not limited to: all driving motor torque zero, stop engine start request (if any) and the like.

[0034] It can be understood that when the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, it may cause serious high-voltage electric shock safety accident, therefore, it is necessary to control the driving system of the vehicle to be in a stop working state in time.

[0035] It should be noted that in response to monitoring that the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, controlling the driving system of the vehicle to be in a stop working state, is to filter out the unstable fault signal, prevent unnecessary fault processing caused by false triggering, reduce the driving experience.

[0036] ​In an optional embodiment, the duration of the high-voltage safety fault of the vehicle can be monitored by the main controller of the vehicle.

[0037] In step S104, in response to monitoring that the target hatch in the vehicle is in an open state, other systems in the vehicle except the driving system are controlled to be in a stop working state, wherein the target hatch is a hatch associated with a high-voltage bus of the vehicle.

[0038] The target hatch can be understood as any hatch that needs high-voltage power-up, which can include but is not limited to front and rear engine covers, AC / DC charging port covers, discharge port covers, chassis covers, etc. The high-voltage bus can be understood as the main line adopted for the connection of the substation high-voltage distribution device and the connection of electrical equipment such as transformers and corresponding distribution devices.

[0039] Specifically, controlling other systems in the vehicle except the driving system to be in a stop working state can be understood as forcibly powering down under high voltage, that is, all forms of high-voltage power-up state are removed, and before the fault is removed, the current driving cycle is prohibited from powering up to high voltage.

[0040] It can be understood that when it is monitored that the target hatch in the vehicle is in an open state, the risk of electric shock for the driver is increased, and therefore it is necessary to control other systems in the vehicle except the driving system to be in a stop working state, and even if the fault is removed, the processing measures in the above steps will not be revoked, and the driver needs to re-enable the power-up request to remove the fault processing measures.

[0041] In step S106, high-voltage safety fault processing is performed on the vehicle to obtain a fault processing result.

[0042] The high-voltage safety fault processing can be understood as a way to remove the high-voltage safety fault of the vehicle, and the fault processing result can be understood as a result obtained after the high-voltage safety fault is processed, which can include but is not limited to successful removal of the high-voltage safety fault, failed removal of the high-voltage safety fault, etc.

[0043] Specifically, the high-voltage safety fault processing can include but is not limited to powering down the driving system under high voltage, maintaining high-voltage power supply of the comfort system, prohibiting charging of the power battery and charging heating, specifically including AC charging, prohibiting AC charging heating, prohibiting DC charging, prohibiting DC charging heating, prohibiting wireless charging, prohibiting wireless charging heating, prohibiting AC discharging, or prohibiting charging and discharging, etc.

[0044] It should be noted that the above driving system under high voltage maintains the high-voltage power supply of the comfort system in order to prevent the low-voltage storage battery from being discharged and prevent the necessary comfort systems such as air conditioning and heating in the vehicle from being shut down.

[0045] In an optional embodiment, the fault processing result can be fed back on the vehicle screen or dashboard in the form of text (e.g., at least one of characters, numbers, letters, etc.) and / or images (e.g., at least one of pictures, patterns, graphics, etc.), for example, in the form of text on the vehicle screen as: "High-voltage safety fault removal success!".

[0046] By the above steps, in response to monitoring that the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, the driving system of the vehicle is controlled to be in a stop working state; in response to monitoring that the target cabin door in the vehicle is in an open state, other systems in the vehicle except the driving system are controlled to be in a stop working state, wherein the target cabin door is a cabin door associated with the high-voltage bus of the vehicle; the vehicle is subjected to high-voltage safety fault processing to obtain a fault processing result. Through the above method, when the high-voltage safety fault of the vehicle lasts for too long, the driving system of the vehicle is controlled to stop working, and when the cabin door associated with the high-voltage bus of the vehicle is open, other systems except the driving system are controlled to stop working, thereby achieving the purpose of providing a safe environment for the processing process of the high-voltage safety fault, thereby realizing the technical effect of improving the safety of fault processing, and further solving the technical problem of poor safety of fault processing in the related art.

[0047] Optionally, in response to monitoring that the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, the driving system of the vehicle is controlled to be in a stop working state, including: in response to monitoring that the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, outputting a fault prompt information, and acquiring the current speed of the vehicle; based on the current speed, the driving system of the vehicle is controlled to be in a stop working state.

[0048] Wherein, the fault prompt information can be understood as a prompt information output to the passenger when the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, for prompting the passenger that the vehicle is in a high-voltage safety fault state at this time, and needs to pay attention to safety, and the current speed can be understood as the current driving speed of the vehicle when the duration of the high-voltage safety fault of the vehicle exceeds the preset duration.

[0049] It can be understood that when the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, the driving system of the vehicle needs to be controlled accordingly according to the current speed of the vehicle.

[0050] In an optional embodiment, the fault prompt information can be fed back on the vehicle screen or dashboard in the form of text (e.g., at least one of characters, numbers, letters, etc.) and / or images (e.g., at least one of pictures, patterns, graphics, etc.), for example, in the form of text on the vehicle screen as: "Please note that the vehicle is currently in a high-voltage fault state".

[0051] Optionally, the driving system of the vehicle is controlled to be in the stop working state based on the current speed, including: in response to the current speed reaching a preset speed, determining whether the vehicle is in a parking state; and in response to the vehicle being in the parking state, controlling the driving system to be in the stop working state.

[0052] The preset speed can be understood as a speed at which the vehicle is considered to be stopped, for example, 0, and the parking state can be understood as a parked state.

[0053] It can be understood that when the duration of the high-pressure safety fault of the vehicle exceeds the preset duration, it is necessary to determine whether the current speed of the vehicle is 0, and then control the driving system to be in the stop working state, that is, further fault handling measures need to be taken in the state that the vehicle is stopped, which is more safe and controllable, and at the same time ensures that the current vehicle will not move unexpectedly, preventing fault escalation and causing secondary harm to personnel.

[0054] In an optional embodiment, the speed sensor can be used to determine whether the current speed reaches the preset speed.

[0055] Optionally, the method further includes: determining whether an electronic parking system in the vehicle is in a target state, and determining whether a current gear of the vehicle is in a target gear; and in response to the electronic parking system being in the target state or the current gear being in the target gear, determining that the vehicle is in the parking state.

[0056] The electronic parking system can be understood as a technology that integrates temporary braking during driving and long-time braking after parking, and realizes parking braking by electronic control, the target state can be understood as a locking state of the electronic parking system, the current gear can be understood as a current gear of the vehicle when the duration of the high-pressure safety fault of the vehicle exceeds the preset duration, and the target gear can be understood as a parking gear.

[0057] Specifically, when the gear of the vehicle is in a parking (Park, P for short) gear, the current speed can be considered to be 0, and when the electronic parking system (Electrical Park Brake, EPB for short) is in a locking state, the vehicle can be considered to be in the parking state.

[0058] It can be understood that the state of the electronic parking system in the vehicle and the current gear of the vehicle are determined to ensure that the current vehicle will not move unexpectedly, preventing fault escalation and causing secondary harm to personnel.

[0059] Optionally, the driving system of the vehicle is controlled to be in the stop working state, including: controlling the driving system to stop working and stopping high-voltage power supply to the driving system, so that the driving system is in the stop working state.

[0060] Specifically, the control driving system stops working, including but not limited to: all drive motor torque zero, stop engine start request, stop high voltage power supply to the driving system, it can be understood as to remove all forms of high voltage power on, before the fault is removed, prohibit high voltage power on.

[0061] In an optional embodiment, the control driving system of the vehicle is in a stop working state, which can also be achieved by the following method: stop power supply, stop the operation of the driving system by cutting off the power supply. This is the simplest, most direct and most effective method; software control, programs can be written or existing software can be used to control the operation of the driving system. For example, using task manager or process manager on the computer to end the related process; hardware control, in some cases, it may be necessary to stop the operation of the driving system by hardware. For example, in a car, the engine and its related components can be turned off by pulling out the ignition key or pressing the emergency stop button; reset the device, if the device fails to shut down normally, it can be restarted to restore its normal state, and in the process, it stops working.

[0062] Optionally, before the high voltage safety fault handling of the vehicle is performed and the fault handling result is obtained, the above method further comprises: in response to monitoring that the power battery of the vehicle is in a charging state, stopping the charging operation of the power battery.

[0063] It can be understood that if the high voltage safety fault handling of the vehicle is performed when the power battery of the vehicle is in a charging state, the risk of electric shock of the passenger may be enhanced, therefore, the charging operation of the power battery needs to be stopped before the high voltage safety fault handling of the vehicle is performed.

[0064] Specifically, stopping the charging operation of the power battery can include but is not limited to: prohibiting AC charging heating, prohibiting DC charging, prohibiting DC charging heating, prohibiting wireless charging, prohibiting wireless charging heating, prohibiting AC discharging, prohibiting charging and discharging, etc.

[0065] Optionally, the above method further comprises: generating a fault code according to the high voltage safety fault, and storing the fault code.

[0066] Wherein, the fault code can be understood as an error code automatically detected by the automobile electronic control system, which is used to indicate that a sensor or actuator has failed. When the car fails, the relevant equipment will record the corresponding error information and convert it into a digital code for technicians to diagnose and repair. By reading these fault codes, the problem can be determined and the correct and effective maintenance operation can be performed.

[0067] It can be understood that when the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, the high-voltage interlock fault code and the fault state can be stored in the vehicle main controller, and an instruction is sent to the instrument controller to light the high-voltage system fault lamp to prompt the user that a high-voltage safety fault has occurred.

[0068] In an alternative embodiment, a fault code can be generated according to the high-voltage safety fault by relying on the fault diagnosis system of the vehicle, which is usually done by professional automobile maintenance personnel or factory equipment. During the inspection process, the system scans all sensors and control units and records any problems found as specific codes to generate a fault code.

[0069] In another alternative embodiment, a fault code can be read by using a reading tool such as an On-Board Diagnostics (OBD).

[0070] In another alternative embodiment, the text (e.g., at least one of characters, numbers, letters, etc.) and / or images (e.g., at least one of pictures, patterns, graphics, etc.) can be displayed on the vehicle screen or instrument panel in the form of "high-voltage interlock fault, will not start after power off" and the above-mentioned text content is broadcasted through a voice broadcast device for 5 seconds to prompt the user that a high-voltage safety fault has occurred.

[0071] Figure 2 is a flowchart of an alternative high-voltage safety fault processing method according to an embodiment of the present application, as shown in Figure 2 the specific process is: step S21, fault recognition and confirmation, i.e. judging whether the duration of the high-voltage safety fault of the vehicle exceeds the preset duration, if no fault occurs, continue to monitor the state of the vehicle; step S22, if it is confirmed that a fault has occurred, proceed to fault storage and prompt; step S23, judge whether the vehicle meets the parking condition, if not, continue to judge; step S24, if yes, proceed to primary fault processing, i.e. control the driving system of the vehicle to be in a stopped working state and stop charging the power battery; step S25, hatch state recognition, if the target hatch is not in an open state, continue to recognize; step S26, if the target hatch is in an open state, proceed to secondary fault processing, i.e. forced high-voltage power off.
