[0002] With the advent of the new energy era, traditional instruments are gradually failing to meet user needs. Based on traditional instruments, commonly used alarms include individual indicator light alarms, individual text alert alarms, and alarms combining indicator lights and text alerts.

[0003] For example, publication number CN105405258B, publication date 2018-10-23, and patent title "Method and Device for Alarming Vehicle Faults" discloses a method for alarming vehicle faults. This method includes the steps of: receiving and acquiring the fault code of the faulty vehicle through a communication interface connected to the faulty vehicle; generating corresponding fault text information based on the fault code; and sending the fault text information to a terminal associated with the faulty vehicle. The aforementioned publication uses text prompts to issue an alarm.

[0004] However, due to continuous technological updates and the proliferation of technical jargon, many of which are difficult for users to understand, minor problems are often misinterpreted as major ones, and major problems are ignored as minor ones. In other words, traditional instrument panel warnings are often ambiguous and fail to clearly indicate which specific part of the vehicle is malfunctioning.

[0005] Therefore, this application proposes a vehicle fault alarm device and a vehicle. Utility Model Content

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The purpose is to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation. It should be noted that the terms "first," "second," etc., used in this application are only for the convenience of describing the technical solution and distinguishing different components, and are not intended to limit this application. To make the technical solution of this utility model clearer, it will be explained and illustrated through the following embodiments.

[0022] This embodiment provides a vehicle fault alarm device, such as Figure 1 As shown, the device includes a vehicle and component model memory, multiple component controllers, a main controller, and a display, wherein the main controller is connected to the vehicle and component model memory, multiple component controllers, and the display.

[0023] Specifically, the vehicle and component model storage is used to provide vehicle and component models to the main controller. These models are created by professional modeling tools (such as CATIA, Blender, 3ds Max, Unity, Kanzi, QT, etc.) based on the current vehicle and are pre-stored in the vehicle and component model storage. The storage includes Flash chips, hard drives, etc., and can be flexibly selected according to needs during implementation.

[0024] Multiple component controllers are used to upload fault information to the main controller when a component fails. The vehicle's component controllers include BCM (Body Control Module), EMS (Energy Management System), ESP (Electronic Stability Program), and PEPS (Keyless Entry and Start System). Furthermore, these component controllers are connected to the main controller via an in-vehicle network, which may include hardwired signals, CAN, LIN, Ethernet, etc., and can be flexibly selected according to specific implementation needs. To reduce costs, in this embodiment, the component controllers are connected to the main controller via a CAN bus.

[0025] In this embodiment, the main controller receives fault information uploaded by multiple component controllers, generates text prompts, converts them into video signals, and sends them to the display. Simultaneously, the main controller also reads the specific faulty component from the text prompts, retrieves the corresponding component model from the vehicle and component model memory, converts it into a video signal, and sends it to the display. It should be noted that in this embodiment, the algorithms used by the main controller are all existing technologies.

[0026] Preferably, the main controller in this embodiment is a microcontroller (MCU), which is a commonly used built-in controller in vehicles. It integrates a variety of functional interfaces and ready-made algorithm program modules. Based on this, the microcontroller (MCU) is directly used as the main controller, which greatly reduces the difficulty of secondary development and eliminates the need to set up a separate controller and wiring, thus reducing costs.

[0027] In this embodiment, the main controller is connected to the display via a video interface, which includes LVDS, HDMI, DP, etc., and can be flexibly selected according to actual needs during implementation.

[0028] The display is used to receive text prompts and video signals of corresponding faulty component models sent by the main controller and display them on the screen. For example, Figure 2 As shown, the display includes a first display area and a second display area. The first display area is located at the center of the display, and the surrounding area serves as the second display area. The first display area is used to display models of the entire vehicle and its components, while the second display area is used to display corresponding text prompts. This combination of text prompts and the display of corresponding faulty component models clearly and three-dimensionally alerts the user to the faulty area, improving the user experience.

[0029] In practical implementation, the first and second display areas can be integrated onto a single display screen to reduce costs; alternatively, each can use a separate display screen, ensuring that if one screen fails, the other can still provide fault information. In this embodiment, the display screen is a TFT color screen, which is connected to the main controller. The TFT color screen features high response speed, wide viewing angle, high brightness, and high contrast, supporting precise color gradation control of tens of thousands of colors, thus improving the clarity of text prompts and model displays.

[0030] In addition, the alarm device in this embodiment also includes a user input module, which is connected to the main controller. The user input module is used to acquire user commands and send them to the controller, such as the display color and angle of the whole vehicle and component models. In specific implementations, the user input module can adopt a human-machine interface (HMI) or similar device.

[0031] This embodiment also provides a vehicle that includes the vehicle fault alarm device described above.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
