[0050] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of hybrid vehicle maintenance equipment in the hardware operating environment involved in the embodiment of the present invention.

The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (NVM), such as a disk storage. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0053] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the maintenance equipment of the hybrid vehicle, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0054] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a maintenance program for a hybrid vehicle.

[0055] exist Figure 1 In the hybrid vehicle maintenance equipment shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the hybrid vehicle maintenance equipment of the present invention can be set in the hybrid vehicle maintenance equipment, and the hybrid vehicle maintenance equipment calls the hybrid vehicle maintenance program stored in the memory 1005 through the processor 1001, and executes the hybrid vehicle maintenance method provided by the embodiment of the present invention.

[0056] The embodiment of the present invention provides a hybrid vehicle maintenance method, referring to Figure 2 , Figure 2 This is a flow chart of a first embodiment of a hybrid vehicle maintenance method according to the present invention.

[0057] In this embodiment, the hybrid vehicle maintenance method includes the following steps:

[0058] Step S10: When a vehicle failure occurs, the current power level of the vehicle battery is obtained.

[0059] It should be noted that the execution subject of this embodiment is the controller on the hybrid vehicle, and it can also be an on-board computer, or other information processing device installed on the hybrid vehicle, or other devices that can achieve this function, etc. This embodiment does not limit this.

[0060] It should be understood that when a vehicle cannot start normally due to a malfunction or lack of fuel, the conventional method is to use maintenance equipment to charge the battery. Only when the power is increased to meet the use requirements can high voltage or engine dragging be applied. Many maintenance points do not have dedicated maintenance equipment, and handling high voltage is extremely dangerous. The solution adopted in this embodiment automatically calculates the corresponding battery limitation mode based on the current power of the vehicle battery when a vehicle malfunctions, and then automatically turns on the maintenance mode to repair the vehicle when a maintenance instruction is received in the high-voltage limited mode, thereby reducing the maintenance conditions and eliminating the need for dedicated maintenance equipment or transferring the vehicle, making the maintenance of hybrid vehicles simpler and more effective.

[0061] In a specific implementation, the vehicle battery refers to the onboard battery of a hybrid vehicle. The vehicle in this embodiment can be a hybrid vehicle of any model and brand, and this embodiment does not impose any limitation on this.

[0062] Furthermore, in order to determine the fault condition of the vehicle, before step S10, it also includes: obtaining engine information; determining the engine working state according to the engine information; when the engine working state is lack of fuel or engine failure, obtaining the current power of the vehicle battery.

[0063] It should be noted that the engine information refers to relevant information such as the current operating parameters of the engine, including but not limited to: speed, temperature, etc.

[0064] It should be understood that determining the engine operating status based on the engine information means: determining whether the current engine is operating normally based on the engine information, and then determining information such as the reason why the engine is not operating normally as the engine operating status.

[0065] In a specific implementation, when the engine operating status is lack of fuel or engine failure, obtaining the current power of the vehicle battery means: when the engine operating status is displayed as abnormal operation and the reason for the abnormal operation is insufficient fuel supply, or the reason is a failure of the engine itself, then obtaining the current power of the vehicle battery, so as to carry out subsequent maintenance process.

[0066] In this way, the engine's working status can be automatically determined based on the engine information, thereby determining whether the conditions for obtaining the current power of the vehicle battery are met. The current power of the vehicle battery is only obtained when there is a lack of fuel or an engine failure.

[0067] Step S20: determining a battery restriction mode corresponding to the vehicle battery according to the current power level.

[0068] It should be noted that determining the battery restriction mode according to the current power level refers to querying a restriction mode comparison table according to the current power level, thereby determining the battery restriction mode corresponding to the current power level.

[0069] It should be understood that the restriction mode comparison table refers to a table that compares battery percentages with battery restriction modes. Specifically, battery restriction modes are divided into three categories: high-voltage restriction mode, driving restriction mode, and battery warning mode. Therefore, the battery percentage is divided into three intervals from 0-100%, corresponding to high-voltage restriction mode, driving restriction mode, and battery warning mode respectively. The values ​​of driving restriction mode, battery warning mode, and high-voltage restriction mode decrease in magnitude.

[0070] Furthermore, in order to control vehicle functions in the restricted driving mode, after step S20, it also includes: when the battery restriction mode is the restricted driving mode, obtaining the vehicle driving mode; determining the current mode according to the vehicle driving mode; switching the vehicle from the current mode to the pure electric drive mode, and outputting fault alarm information.

[0071] In a specific implementation, when the battery level is determined to be within the range corresponding to the battery limit mode based on the current power level, that is, the battery level is sufficient for continued driving, when the battery limit mode is determined to be the restricted driving mode, the vehicle's current driving mode is first obtained. Since the vehicle is a hybrid vehicle, the driving mode can be fuel-powered, electric-powered, or hybrid-powered.

[0072] It should be noted that determining the current mode according to the vehicle driving mode means: determining, according to the vehicle driving mode, whether the driving mode currently adopted by the vehicle is fuel, pure electric, or hybrid.

[0073] It should be understood that switching the vehicle from the current mode to the pure electric drive mode and outputting a fault alarm message means: switching the current mode of the vehicle to the pure electric drive mode for driving, that is, prohibiting the use of the engine for driving, and using battery power for driving, and then automatically generating an engine failure fault alarm message output to prompt the user, thereby reminding the user that the engine has a fault.

[0074] In a specific implementation, when in restricted driving mode, the current charge level of the vehicle battery is continuously monitored. If the current charge level reaches the upper limit of driving, the vehicle is forced to stop.

[0075] In this way, the vehicle's driving behavior can be accurately restricted when the vehicle is in the restricted driving mode, and the engine can be stopped in time to avoid safety accidents.

[0076] Furthermore, in order to be able to control the driving of the vehicle in the power alarm mode and avoid the vehicle breaking down, after step S20, it also includes: when the battery limitation mode is the power alarm mode, monitoring the start-up instruction issued by the vehicle system; when there is a battery call instruction in the start-up instruction, prohibiting the battery call instruction; generating an instruction according to the battery call instruction to prohibit recording and displaying it to the user.

[0077] It should be noted that when the current power level of the vehicle battery is within the value range corresponding to the power level alarm mode, the battery limit mode is set to the power level alarm mode, and then the start command issued by the vehicle system is monitored.

[0078] It should be understood that the start-up instruction refers to an instruction issued by the vehicle system to start any function, component or software in the vehicle.

[0079] In a specific implementation, if a startup command contains a battery call instruction, which means that the function, component, or hardware activated in the startup command requires battery power, that is, directly consumes power from the vehicle battery, the battery call instruction is prohibited. In other words, if a startup command contains an instruction that directly consumes battery power, battery call instruction is directly prohibited.

[0080] It should be noted that generating instruction prohibition recording according to the battery call instruction and displaying it to the user means: generating a list of all prohibited battery call instructions and corresponding times according to the battery call instruction, thereby prompting the user of the prohibited function.

[0081] In this way, the battery can be directly managed in the power alarm mode, and the battery call instructions are prohibited, thereby ensuring that the current power of the vehicle will not decrease further, leaving reserve power for high voltage maintenance of the vehicle in the maintenance mode.

[0082] Step S30: when the battery limiting mode is the high voltage limiting mode, obtaining an input action instruction.

[0083] In a specific implementation, when the battery limit mode is high voltage limit mode and the vehicle's current battery level is within the corresponding value range of high voltage limit mode, the system begins to continuously monitor and receive input action commands. Action commands can be any type of command input by the user through voice, gestures, or the vehicle screen.

[0084] Step S40: When the action instruction is a maintenance instruction, the vehicle maintenance mode is turned on to perform maintenance on the vehicle.

[0085] It should be noted that after all action instructions are identified and determined to be maintenance instructions, the vehicle maintenance mode is turned on, and a vehicle maintenance strategy is generated in the maintenance mode, so that the vehicle can be maintained according to the vehicle maintenance strategy.

[0086] This embodiment obtains the current battery charge level of the vehicle battery when a vehicle malfunctions; determines the corresponding battery restriction mode for the vehicle battery based on the current charge level; receives an input action instruction when the battery restriction mode is the high-voltage limit mode; and, when the action instruction is a maintenance instruction, activates the vehicle's maintenance mode to perform vehicle maintenance. This method automatically calculates the corresponding battery restriction mode based on the current battery charge level when a vehicle malfunctions. Upon receiving a maintenance instruction while in the high-voltage limit mode, the maintenance mode is automatically activated to perform vehicle maintenance. This reduces maintenance requirements, eliminates the need for dedicated maintenance equipment or vehicle relocation, and makes hybrid vehicle maintenance simpler and more efficient.

[0087] refer to Figure 3 , Figure 3 This is a flow chart of a second embodiment of a hybrid vehicle maintenance method according to the present invention.

[0088] Based on the first embodiment described above, the hybrid vehicle maintenance method of this embodiment includes, in step S40:

[0089] Step S401: Obtain the instruction behavior corresponding to the action instruction.

[0090] It should be noted that the instruction behavior corresponding to the action instruction refers to: the user's behavior corresponding to the action instruction, including but not limited to: voice, use of vehicle operating levers, pedals and other behaviors.

[0091] Step S402: determining the action type and action time of each operation action according to the instruction behavior.

[0092] It should be understood that after the command behavior is determined, the corresponding operational actions for all command behaviors are determined, as well as the type of each operational action and the start time and duration of each operational action. Operational actions may include, but are not limited to, braking, pressing the driving mode switch simultaneously for more than 10 seconds, and then pressing the vehicle start switch.

[0093] Step S403: Determine the instruction type of the action instruction according to the action type and the action time.

[0094] In a specific implementation, determining the instruction type of the action instruction based on the action type and the action time means: sorting each operation action in chronological order and duration according to the action type and action time to form an action combination corresponding to the action instruction, and then comparing the action combination with the maintenance action combination corresponding to the maintenance instruction to determine whether the instruction type of the action instruction is a maintenance instruction or another instruction. Specifically, when the action combination is consistent with the maintenance action combination, the action instruction is determined to be a maintenance instruction.

[0095] Step S404: When the instruction type of the action instruction is a maintenance instruction, the vehicle maintenance mode is turned on.

[0096] It should be noted that, after determining that the instruction type of the action instruction is a maintenance instruction, the vehicle maintenance mode is turned on through the vehicle system, that is, all configurations of the vehicle are set to the vehicle maintenance mode.

[0097] Step S405: Formulate and execute a vehicle maintenance strategy according to the vehicle maintenance mode.

[0098] It should be understood that formulating and executing a vehicle maintenance strategy according to the vehicle maintenance mode refers to determining the electrical appliance information of the vehicle according to the vehicle maintenance mode, and then setting the vehicle maintenance strategy according to the electrical appliance information.

[0099] Furthermore, in order to specify a safer and more efficient vehicle maintenance strategy, step S405 includes: when the vehicle is in the vehicle maintenance mode, obtaining vehicle electrical appliance information; determining the status of each high-voltage electrical appliance based on the vehicle electrical appliance information; determining the operable high-voltage electrical appliances based on the high-voltage electrical appliance status; setting the vehicle maintenance strategy to prohibit the use of the operable high-voltage electrical appliances and allow the high-voltage motor of the engine to be started; and executing the vehicle maintenance strategy.

[0100] In a specific implementation, the vehicle electrical appliance information refers to the relevant information of all electrical appliances or hardware parts that consume electricity on the vehicle.

[0101] It should be noted that determining the status of each high-voltage electrical appliance according to the vehicle electrical appliance information refers to determining the operating status of all high-voltage electrical appliances requiring high voltage electricity according to the vehicle electrical appliance information.

[0102] It should be understood that determining operable high-voltage electrical appliances based on the status of the high-voltage electrical appliances means: determining the names and equipment numbers and other information of all high-voltage electrical appliances on the vehicle that can be started and operated normally based on the status of the high-voltage electrical appliances.

[0103] In a specific implementation, setting the vehicle maintenance strategy to prohibit the use of the operable high-voltage electrical appliances and allowing the high-voltage motor of the engine to be started means: after determining the operable high-voltage electrical appliances, the vehicle maintenance strategy is specified to not allow all operable high-voltage electrical appliances to be used, and only allow the high-voltage motor on the engine to operate.

[0104] In this way, only high-voltage motors are allowed to perform high-voltage operations for vehicle maintenance, and the use of other high-voltage electrical appliances is prohibited, preventing excessive consumption of battery power that affects maintenance and reducing safety hazards of other high-voltage electrical appliances during the maintenance process.

[0105] Furthermore, in order to protect the vehicle battery, after executing the step of the vehicle maintenance strategy, it also includes: when it is detected that the high-voltage motor is started, the number of times the high-voltage motor drags the engine is started is recorded; when the number of starts reaches the upper limit of the start threshold, the high-voltage motor is turned off, and a high-voltage alarm message is sent to the user.

[0106] It should be noted that when the high-voltage motor is detected to be started, recording the number of times the high-voltage motor drives the engine to start means: each time the high-voltage motor is detected to be started, the number of times the high-voltage motor drives the engine to start is recorded and accumulated.

[0107] It should be understood that after the cumulative number of starts is compared with the upper start threshold, if the number of starts reaches the upper start threshold, the high-voltage motor is immediately shut down and a high-voltage warning message is sent to the user. The start threshold is any positive integer upper limit set by the user and can be any value, which is not limited in this embodiment. The high-voltage warning message is any type of information used to inform the user that the high-voltage motor has been started too many times.

[0108] In this way, the number of times the high-voltage motor is started to drag the engine is continuously recorded during the maintenance process, so as to avoid excessive starting of the motor to drag the engine during the maintenance process, which may cause damage to the high-voltage motor and the engine.

[0109] This embodiment obtains the instruction behavior corresponding to the action instruction; determines the action type and action time of each operation based on the instruction behavior; determines the instruction type of the action instruction based on the action type and action time; activates vehicle maintenance mode when the instruction type of the action instruction is a maintenance instruction; and formulates and executes a vehicle maintenance strategy based on the vehicle maintenance mode. In this way, it is possible to determine whether the user's action instruction is a maintenance instruction and implement the vehicle maintenance strategy in the maintenance mode to assist in maintenance, making maintenance possible without specialized equipment.

[0110] In addition, an embodiment of the present invention further provides a storage medium on which a hybrid vehicle maintenance program is stored. When the hybrid vehicle maintenance program is executed by a processor, the steps of the hybrid vehicle maintenance method described above are implemented.

[0111] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
