Description

Technical Field

[0001] The utility model belongs to the field of new energy vehicles. Specifically, the utility model relates to a display device and a vehicle for the energy recovery intensity level of a new energy vehicle. Background Art

[0002] With the progress of new energy vehicle technology, new energy vehicles are gradually popularized globally. An important reason for the energy conservation of new energy vehicles is that energy can be recovered during braking and coasting, converting kinetic energy into electrical energy and storing it in the battery. This can not only provide energy for the next drive but also assist the brake disc in braking, thereby reducing the wear of brake pads. However, during the energy recovery process, there will be a certain sense of drag. Since everyone's perception and tolerance to the drag are different, generally, three levels of energy recovery intensity, namely "high intensity", "medium intensity", and "low intensity", are designed to meet the needs of different people.

[0003] The comparative document (CN110877529A) relates to a pure electric vehicle and its energy recovery control method and control system. The method aims to effectively recover different degrees of braking energy to meet the different needs of users for vehicle comfort and endurance. However, this comparative document does not consider the display problem of the energy recovery intensity level and cannot meet the requirement of the driver to know the energy recovery intensity level in real time.

[0004] Existing methods and devices for displaying the energy recovery intensity level generally correspond to display the corresponding energy recovery intensity level status through the Chinese characters "high, medium, low" or the initials "H, M, L" of the English words HIGH, MIDDLE, LOW. At the same time, it requires a relatively large display area on the driving information display surface, cannot be applied to the design scheme with increasingly reduced size and continuously compressed cost, and cannot meet the display needs of different language countries and regions at the same time. For different countries, it is necessary to re-design and develop, resulting in an increase in development and design costs. Summary of the Utility Model

[0005] The utility model aims to overcome the deficiencies of the prior art and proposes a display device and a vehicle for the energy recovery intensity level of a new energy vehicle to achieve the following purposes: realizing the real-time display of the energy recovery intensity level to meet the display needs of different language countries and regions, and saving the development and design costs and cycle.

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 This is a structural diagram of a display device for the energy recovery intensity level of a new energy vehicle according to an embodiment of the present utility model. DETAILED DESCRIPTION

[0018] The following, with reference to the accompanying drawings, further illustrates the specific implementation methods of the present invention through the description of the embodiments, with the aim of helping those skilled in the art to have a more complete, accurate, and in-depth understanding of the utility model concept and technical solution of the present invention and to facilitate its implementation. It should be noted that the terms "first" and "second" in this application are only used to facilitate the description of the technical solution to distinguish different components and are not intended to limit this application. To make the technical solution of the present invention more clear, the present invention is explained through the following embodiments.

[0019] A display device for the energy recovery intensity level of new energy vehicles, such as Figure 1 As shown, the device includes a first controller, a second controller, an energy recovery execution module, and a display screen, wherein the first controller is connected to the second controller for setting the energy recovery intensity level; the second controller is connected to the energy recovery execution module for controlling the energy recovery execution module to execute according to the corresponding energy recovery intensity level; the display screen is connected to the second controller for displaying the executed energy recovery intensity level.

[0020] It should be noted that the various components of the device of this embodiment are connected using the vehicle communication harness CAN bus. The CAN bus has the advantages of high transmission rate and stable transmission signal, thereby ensuring the real-time and reliability of the display of the device of this embodiment.

[0021] Specifically, the first controller in this embodiment utilizes an in-vehicle entertainment unit (IHU), which is widely used in new energy vehicles and enables human-machine interaction with the driver. In this embodiment, the driver uses the IHU to set the energy recuperation intensity level ("high intensity," "medium intensity," or "low intensity") based on their needs. This level then sends a signal to the second controller via the CAN bus to set the energy recuperation intensity status.

[0022] In a preferred embodiment of the present application, the device of this embodiment further includes a face recognition camera, which is connected to the first controller (i.e., the in-vehicle entertainment host IHU). The in-vehicle entertainment host IHU pre-saves the energy recovery intensity levels set by the driver and the face information of the corresponding driver. When the corresponding driver drives, the in-vehicle entertainment host IHU automatically matches the corresponding energy recovery intensity level according to the image data of the face recognition camera, avoiding the driver from repeatedly setting the energy recovery intensity level. Thus, while providing convenience for the driver, the most suitable energy recovery intensity level is matched for the driver, improving the driving experience.

[0023] The second controller of this embodiment is the vehicle controller VCU. The vehicle controller VCU has high-efficient data processing capabilities and supports the data analysis of multiple sensors, so as to be able to accurately control the vehicle components. In this embodiment, after receiving the energy recovery intensity state setting signal, the vehicle controller VCU identifies and controls the energy recovery execution module to execute the corresponding energy recovery intensity level, and at the same time sends the energy recovery intensity state execution signal to the display screen through the CAN bus.

[0024] In this embodiment, the energy recovery execution module includes a sensor unit, a motor controller, and a motor. The sensor unit and the motor controller are respectively connected to the second controller (vehicle controller VCU), and the motor controller is connected to the motor. Among them, the sensor unit includes a vehicle speed sensor, a brake pedal position sensor, a battery BMS (battery management system), an acceleration sensor, etc., and each sensor unit is connected to the second controller. The vehicle controller VCU monitors the vehicle and motor states in real time through the sensor module, and after data analysis, the vehicle controller VCU sends a signal to the motor controller to control the motor to execute the corresponding energy recovery intensity level.

[0025] The display screen of this embodiment includes a status display module and a digital display module. The status display module and the digital display module are respectively connected to the second controller. The status display module and the digital display module respectively represent different display areas on the display screen, and their display contents can be controlled by the vehicle controller VCU. In a feasible embodiment of the present application, the status display module and the digital display module can also be displayed through two display screens respectively.

[0026] Specifically, after the display screen receives the energy recovery intensity status execution signal from the vehicle controller VCU and processes and identifies it, the status display module parses it to determine whether the energy recovery status is on, and displays it through status display methods such as icons and indicator lights; at the same time, next to the status display module, the digital display module parses the energy recovery intensity level from the energy recovery intensity status execution signal, and displays the corresponding energy recovery intensity level digitally. For example, in this embodiment, "high intensity" is displayed as 3, "medium intensity" is displayed as 2, and "low intensity" is displayed as 1.

[0027] Arabic numerals are universally used worldwide. This application, through the use of Arabic numerals, can simultaneously meet the display requirements of countries and regions with different languages, thereby saving development and design costs and cycles. Furthermore, through the display method of combining icons and Arabic numerals, this application can keep the icons unchanged when switching between display levels, and only change the display of Arabic numerals, thus saving a large amount of display area and making it flexible for application on increasingly compact LCD color screens and color screens made of broken code materials.

[0028] At the same time, the present application also proposes a vehicle, which includes the above-mentioned display device for the energy recovery intensity level of a new energy vehicle.

[0029] The above description of the present invention is provided as an example, in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any application of the above-described concepts and technical solutions of the present invention to other situations without modification, are all within the scope of protection of the present invention.
