[0002] New energy vehicles have gradually become the mainstream trend of the automobile market due to their environmental protection and energy saving characteristics. However, despite the significant progress made in terms of range and charging infrastructure, the problem of "range anxiety" remains one of the important factors restricting its further popularization. The "range anxiety" of new energy vehicles mainly stems from consumers' uncertainty about the vehicle's range and their dependence on charging facilities. When traveling long distances or in remote areas, consumers often worry that the vehicle will run out of power and be unable to reach the destination or find a suitable charging station. In order to alleviate this problem, automobile manufacturers usually take measures such as increasing battery capacity and improving charging speed. However, these methods not only improve the range, but also increase the weight and cost of the vehicle, which has a certain impact on the energy consumption and performance of the whole vehicle.

[0003] In addition to the improvement of battery technology, reducing the energy consumption of the vehicle in unnecessary states is also one of the effective ways to solve "range anxiety". In new energy vehicles, the display screen is an important information display and interaction interface, and its energy consumption accounts for a certain proportion of the overall energy consumption of the vehicle. In particular, during vehicle travel, various types of display screens inside the vehicle (such as instrument display screens, center control screens, electronic rearview mirrors, co-pilot display screens, and rear entertainment screens) are often in a continuous lighting state.

[0033] Embodiment one of the utility model automobile energy-saving system

[0034] Please refer to Figures 1-3 The utility model automobile energy-saving system includes:

[0035] At least one wide-angle infrared camera is installed in the vehicle interior for capturing the face deflection direction and eye pupil information of the vehicle personnel;

[0036] The display screen control unit is connected with the wide-angle infrared camera, is used for receiving the information captured by the camera, and is also used for judging whether the person in the vehicle is watching the display screen or not, so as to control the on-off of the display screen; the present application aims to reduce the energy consumption of the vehicle display screen through intelligent means, thereby effectively prolonging the cruising range of the new energy vehicle, relieving the journey anxiety of the user, and specifically, the present application installs a wide-angle infrared camera at a key position in the vehicle, captures the face deflection direction and eye pupil information of the person in the vehicle by the camera, and intelligently controls the on-off state of the display screen; only when the person in the vehicle needs to view the screen, the corresponding display screen will be turned on, thereby realizing the precise distribution and efficient utilization of energy; this energy-saving scheme not only improves the energy utilization efficiency of the new energy vehicle, but also enhances the intelligence and comfort of driving.

[0037] Further, as shown in Figures 1-3 The display screens in the vehicle are connected with the display screen control unit, so as to realize the control of the display screen control unit on the on-off state of the display screen; all the display screens in the vehicle are uniformly managed, so that the energy-saving control is more efficient and convenient; through centralized control of multiple display screens by one control unit, the complexity and energy waste caused by independent control of each display screen can be avoided, and at the same time, unified parameter setting and management of the display screens in the whole vehicle can be facilitated, thereby improving the overall stability and reliability of the system.

[0038] Further, the display screen in the vehicle is an LCD display screen, which includes a backlight unit and a TFT unit; the LCD display screen has good display effect and low energy consumption, can meet the visual demand of the user while reducing the overall energy consumption of the vehicle, and the combination of the backlight unit and the TFT unit makes the display screen display images more clearly and brightly, and also can reduce energy consumption by reasonably controlling the brightness of the backlight unit; because the LCD display screen is relatively mature in technology, its display effect is stable and the color restoration degree is high, the brightness of the backlight unit can be adjusted according to actual needs, when the ambient light is relatively dark, the backlight brightness can be reduced to reduce energy consumption; when the ambient light is relatively bright, the backlight brightness can be appropriately increased to ensure the clarity of the display screen; the TFT unit is responsible for controlling the on-off state of each pixel point to realize the display of images; this combination not only guarantees the display quality of the display screen, but also effectively reduces the energy consumption.

[0039] Further, the TFT unit is lit when the vehicle starts, and the backlight unit is turned on and off under the control of the display screen control unit; when the vehicle starts, the lighting of the TFT unit can ensure that the display screen has a certain display state to provide basic information display for the user, and the backlight unit can be turned on and off according to the actual needs of the vehicle personnel under the intelligent control of the display screen control unit, thereby further reducing energy consumption. This design not only ensures the basic functional requirements when the vehicle starts, but also maximizes energy saving in the subsequent use process. The reason is that the lighting of the TFT unit can enable the user to quickly understand some key information such as the state of the vehicle and navigation information after the vehicle starts; and the intelligent control of the backlight unit can determine whether the backlight needs to be lit according to the line-of-sight information of the vehicle personnel captured by the wide-angle infrared camera, and if the vehicle personnel are not watching the display screen, the backlight unit can remain off, thereby greatly reducing the energy consumption of the display screen.

[0040] Further, the wide-angle infrared camera is arranged at the in-vehicle display screen. Arranging the wide-angle infrared camera at the in-vehicle display screen can more accurately capture the action of the vehicle personnel watching the display screen, improve the detection accuracy of the system, and also make the installation position of the camera more reasonable and not occupy too much in-vehicle space.
