[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0040] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] The embodiment of the present invention provides a fault alarm method, combined with Figure 1 As shown in the flowchart, the method includes steps 101 to 103:

[0042] Step 101: If target fault information is detected, obtain the vehicle's current driving information and co-driver status information;

[0043] In this embodiment, the vehicle may malfunction, and when a malfunction occurs, the vehicle will issue a fault alarm. However, in some special scenarios, if the appropriate fault alarm mode is not selected when the vehicle malfunctions, it may startle the driver. This is especially true in complex driving conditions where the driver's attention is highly focused, and a sudden fault alarm may disrupt the driver's driving. For example, when driving at high speeds, the driver's attention is highly focused, while traditional fault alarms are mostly audible and visual. To achieve the desired alarm prompt, the alarm sound is loud, which can easily startle a highly focused driver, thereby affecting driving safety.

[0044] In addition, for some novice drivers, due to their lack of driving experience, they tend to be nervous when driving. If a fault alarm suddenly occurs, it may interfere with the driver's normal driving, thus affecting driving safety.

[0045] It should be noted that some vehicle faults are more serious and will affect driving, and such faults need to be reported to the driver in a timely manner. However, some faults are less serious and do not require timely troubleshooting, so it is acceptable to wait until the driver stops the car to handle the fault.

[0046] Therefore, this embodiment uses faults that affect driving and require timely treatment as target faults, such as battery pack faults, brake faults, generator faults, etc.

[0047] When a target fault occurs in a vehicle, the vehicle will detect the target fault information.

[0048] In this embodiment, when the vehicle detects the presence of target fault information and needs to issue a fault alarm to the people in the vehicle, the current driving information of the vehicle and the co-driver status information will be obtained first.

[0049] Among them, driving information refers to parameter information used to judge the driving conditions of the vehicle when it is in motion. Driving information includes vehicle speed, weather information, vehicle location information, map information, etc.

[0050] In this embodiment, the passenger seat status information refers to information used to indicate whether there is a passenger on the passenger seat. Whether the passenger seat is a passenger can be detected by a camera in the vehicle or a pressure sensor on the passenger seat.

[0051] Step 102: determining whether the vehicle is in a target driving condition based on the driving information;

[0052] After obtaining the vehicle's current driving information and co-driver status information, the vehicle's current driving condition can be determined based on the driving information, thereby determining whether the vehicle is in the target driving condition.

[0053] It should be noted that the target driving conditions are those with more complex driving conditions, such as high-speed driving, long downhill driving, driving on continuous curves, and driving in foggy weather. Under the target driving conditions, the driver is required to pay close attention to driving.

[0054] In this embodiment, the steps for determining whether the vehicle is in the target driving condition may include:

[0055] If the weather information is heavy fog, heavy rain, or heavy snow, the vehicle is in the target driving condition;

[0056] If the vehicle speed is greater than 100 km / h, the vehicle is in the target driving condition;

[0057] If it is determined based on the vehicle position information and map information that the vehicle is on a highway section, a long downhill section, or a continuous curved road section, etc., then the vehicle is in the target driving condition.

[0058] Step 103: If the vehicle is in the target driving condition, a fault alarm mode is determined according to the co-pilot status information and a fault alarm is performed.

[0059] In this embodiment, when it is determined that the vehicle is in the target driving condition, it indicates that the current driving environment is complex and the driver needs to drive carefully. At this time, the driver's attention is relatively focused.

[0060] It's important to note that a vehicle may have other passengers besides the driver. If there's a passenger in the passenger seat, the fault alarm can be simultaneously alerted to the passenger, who can then be informed of the driver's specific fault alarm details. This not only provides a fault alarm, but also provides a notification method that better suits the specific driving conditions.

[0061] If there is no passenger in the front passenger seat, when performing a fault alarm, it is possible to consider a fault alarm mode only for the driver.

[0062] In one embodiment, the step of determining a fault alarm mode and performing a fault alarm based on the co-pilot status information may include:

[0063] If the passenger seat status information indicates that there is a passenger in the passenger seat, the steering wheel is controlled to vibrate and a fault pop-up window is sent to the in-vehicle infotainment system.

[0064] This means there's a passenger in the passenger seat. When a fault alarm is triggered, the steering wheel vibrates, gently alerting the driver. A pop-up notification is then sent to the in-vehicle infotainment system, where it appears on the car's screen. The passenger in the passenger seat can see the specific fault alarm information on the screen, for example, noting a battery pack or thermal management system failure.

[0065] If the front passenger passenger does not notice the fault pop-up window in time, the driver can also communicate with the front passenger passenger to remind the passenger to check.

[0066] It should be noted that some fault alarms are more urgent. In order to ensure that the people in the car know the fault alarm information accurately and promptly, this embodiment detects whether there is target information input by the user within the first preset time of sending the fault pop-up window; wherein the user is the passenger in the car. Target information refers to the information input by the user according to the requirements of the fault pop-up window. The target information can confirm feedback information or command operation information. For example, the user is required to click the confirmation button on the screen. Or the user is required to operate according to the content of the fault pop-up window information, for example, it is necessary to turn on the double flash or the fog lights. In this embodiment, the first preset time can be 5 seconds, 8 seconds, etc., and this embodiment does not limit this.

[0067] If the user-entered target information is not detected, the vehicle's flashes will activate and a voice prompt will be played. This indicates that the front passenger passenger cannot follow the prompts in the fault pop-up window to provide feedback, and therefore may not be able to inform the driver of the fault alarm. In this case, the vehicle will automatically activate the flashes and generate a voice prompt to inform the driver.

[0068] In one embodiment, the step of determining a fault alarm mode and performing a fault alarm based on the co-pilot status information may include:

[0069] If the passenger seat status information indicates that there is no passenger in the passenger seat, controlling the steering wheel to vibrate;

[0070] According to the target fault information, a voice prompt message is generated and played.

[0071] The passenger seat status information "No Passenger" indicates that there is no passenger in the passenger seat, and the driver is the only one in the front seat. When a fault alarm is issued, this embodiment first controls the steering wheel to vibrate to prepare the driver. Then, a voice prompt is generated and played based on the target fault information, so that the driver can understand the specific content of the fault alarm.

[0072] It should be noted that some fault alarms are urgent and may affect driving, requiring prompt action. Therefore, some voice prompts may contain instructions that require prompt action and response from the user, such as turning on the hazard lights, turning on the fog lights, reducing speed, and stopping the vehicle.

[0073] Specifically, the method further includes:

[0074] If the voice prompt information contains a target instruction, detecting whether there is target information input by the user corresponding to the target instruction within a second preset time;

[0075] If it is detected that there is no target information input by the user, the vehicle is controlled according to the target instruction.

[0076] In this embodiment, the target instruction is preset. If the target instruction is included in the voice prompt information, the user is required to take corresponding measures within a preset second time period. If the user inputs the corresponding target information according to the target instruction, the vehicle is controlled in response to the target information input by the user.

[0077] If the user does not enter the corresponding target information within the preset second time, the vehicle will be selectively controlled according to the target command. It should be noted that vehicle control here does not include driving control, such as reducing speed or braking. Selective vehicle control is limited to non-driving control such as turning on the hazard lights and fog lights.

[0078] Furthermore, when a target fault is detected and the driver is alerted, it's best to stop and investigate as soon as possible. This may require a change in the intended route. To address this need, the vehicle in this embodiment acquires map information and vehicle location information. Based on this information, it then determines the nearest parking location. If the driver needs to stop and investigate nearby, they can issue a voice or manually enter a navigation switch command. Upon detecting the user's navigation switch command, the vehicle switches the nearest parking location to the destination. The driver then continues driving according to the switched navigation and can quickly stop and investigate.

[0079] In summary, the embodiments of this specification provide a fault alarm method that, upon detecting the presence of target fault information, obtains the vehicle's current driving information and passenger status information; based on this driving information, determines whether the vehicle is in the target driving condition; and if so, determines a fault alarm mode based on the passenger status information and issues a fault alarm. In this way, when a target fault is detected and the driver needs to be alerted, the corresponding fault alarm mode is selected in complex driving situations by combining the passenger status information with the driving information. This method notifies the driver of the fault while avoiding startling the driver and ensuring driving safety.

[0080] Based on the same inventive concept, combined Figure 2 As shown, an embodiment of the present invention further provides a fault alarm device, comprising:

[0081] The detection module is used to obtain the vehicle's current driving information and co-pilot status information when detecting the presence of target fault information;

[0083] The fault alarm module is used to determine a fault alarm mode and perform a fault alarm according to the co-pilot status information when the vehicle is in a target driving condition.

[0084] Optionally, the fault alarm module is also used to:

[0085] If the passenger seat status information indicates that there is a passenger in the passenger seat, the steering wheel is controlled to vibrate and a fault pop-up window is sent to the in-vehicle infotainment system.

[0086] Optionally, the fault alarm module is also used to:

[0093] If the voice prompt information contains a target instruction, detecting whether there is target information input by the user corresponding to the target instruction within a second preset time;

[0094] If it is detected that there is no target information input by the user, the vehicle is controlled according to the target instruction.

[0095] Optionally, the fault alarm module is also used to:

[0096] Obtain map information and vehicle location information;

[0097] Determining the nearest parking location information based on the map information and the vehicle location information;

[0098] When a navigation switching instruction from the user is detected, the most recent parking location information is switched to the destination.

[0099] Optionally, the navigation switching instruction is a voice instruction.

[0100] In summary, the fault alarm device provided in the embodiments of this specification detects the presence of target fault information, obtains the vehicle's current driving information and passenger status information, determines whether the vehicle is in the target driving condition based on the driving information, and, if so, determines a fault alarm mode based on the passenger status information and issues a fault alarm.
