[0046] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0047] Figure 1 A vehicle backlight adaptive adjustment control system according to the present application is shown, comprising a control device, a light-emitting component and a detection element. The light-emitting components are respectively arranged in a plurality of predetermined areas of the vehicle and are respectively connected to the control device. The detection elements are respectively arranged in a plurality of predetermined areas and are respectively connected to the control device for respectively detecting a plurality of predetermined areas. The control device controls the light-emitting components individually or collectively according to the current mode of the vehicle, and controls whether the light-emitting components are lit according to the signals detected by the detection element.

[0048] According to the vehicle backlight adaptive adjustment control system of the first aspect of the present application, the control device controls the light-emitting components individually or uniformly according to the current mode of the vehicle, and controls whether the light-emitting components are lit according to the signals detected by the detection elements, so that the light-emitting components can be controlled individually in the energy-saving priority mode, and the corresponding light-emitting components can be turned off when the detection element detects that there is no one in the predetermined area, thereby reducing the power consumption of the light-emitting components, saving electricity, and increasing the cruising range of the new energy vehicle.

[0049] Optionally, the current mode of the vehicle includes a first mode and a second mode. When the vehicle is in the first mode, the control device controls the light-emitting components individually, and controls whether the light-emitting components are lit according to the signal detected by the detection element. The first mode can be an energy-saving, economical, etc. mode, with reducing power consumption as a priority. When the vehicle is in the second mode, the control device uniformly controls the light-emitting components to light up, and the second mode can be a normal mode to ensure the use of the light-emitting components of the entire vehicle.

[0050] Furthermore, the present application mainly adopts the detection of car seats to determine whether there are people in the predetermined area. In detail, the detection element includes a seat gravity sensor arranged in the seats of each predetermined area of ​​the vehicle, the seat gravity sensor is connected to the control device, the seat gravity sensor detects whether there are people on the seat and transmits a signal to the control device, and the control device controls whether the light-emitting component is lit according to whether there are people in the seats corresponding to the predetermined area. The seat gravity sensor is a thin film contact sensor, and the contacts of the seat gravity sensor are distributed on the force-bearing surface of the seat. When a person sits on the car seat, the seat gravity sensor closes the contacts after being subjected to external pressure, thereby sending a signal to the control device, thereby detecting that there are people in the area where the seat is located.

[0051] In addition, when a person opens the door but has not sat in, the light-emitting component should also light up the backlight according to actual use requirements. Specifically, the control device is associated with the door opening signal, and the control device determines whether to control the light-emitting component to light up according to whether the door is opened.

[0052] If the seat is occupied, the control device sends a backlight signal of the predetermined area to the light-emitting component in the predetermined area corresponding to the seat, so that the light-emitting component in the corresponding predetermined area lights up the backlight; if the seat is unoccupied, the control device stops sending the backlight signal of the predetermined area to the light-emitting component in the predetermined area corresponding to the seat, so that the light-emitting component at the corresponding seat does not light up the backlight.

[0053] Corresponding to the situation where there is no one in the seat, if the door is open, the control device sends a backlight signal of a predetermined area to the light-emitting component in the predetermined area corresponding to the door, so that the light-emitting component in the corresponding predetermined area lights up the backlight; if the door is closed and there is no one in the seat at the corresponding door, the control device stops sending the backlight signal to the light-emitting component at the corresponding door, so that the light-emitting component at the corresponding door does not light up the backlight; if the door is closed and there is someone in the seat at the corresponding door, the control device sends a backlight signal to the light-emitting component at the corresponding door, so that the light-emitting component at the corresponding door lights up the backlight.

[0054] From the above, it can be seen that the present application associates the detection element and the door opening signal with the control device respectively, so as to light up the backlight of the light-emitting component in the predetermined area when there is someone in the predetermined area, thereby saving electricity while ensuring normal use by personnel, thereby increasing the cruising range of the electric vehicle, and the control logic is precise and efficient.

[0055] As for the control of the light-emitting components, it can be selected that the control device maintains a backlight signal to light up the light-emitting components, and the detection element includes a seat gravity sensor, and the light-emitting components in a predetermined area are associated with the door opening signal and the seat gravity sensor. When the seat gravity sensor detects that there is no one on the seat and the door is closed, the light-emitting components in the predetermined area receive the backlight off signal and turn off the backlight, thereby simplifying the control logic.

[0056] Optionally, the predetermined area includes a front row area and a rear row area.

[0057] Furthermore, the front row space includes the main driving area and the co-pilot area, and the rear row space includes the left rear area and the right rear area. In other words, the predetermined area includes the main driving area, the co-pilot area, the left rear area, and the right rear area. By adopting a finer area division, the backlight of the light-emitting components in the predetermined area can be further accurately controlled, further reducing energy consumption.

[0058] like Figure 1 As shown, the luminous components include a control panel, an instrument cluster, and a large multimedia screen, etc. Optionally, the luminous components may also include a headrest screen and ambient lights, etc., which may be actually determined based on the in-vehicle configuration functions.

[0059] Reference Figure 1 A first photoelectric conversion device is provided between the light-emitting component and the control device. The control device transmits the optical signal to the first photoelectric conversion device through the optical fiber network. The first photoelectric conversion device converts the optical signal into an electrical signal and transmits it to the light-emitting component through CANFD (Controller Area Network with Flexible Data-Ra) communication. Compared with CAN (Controller Area Network), CANFD improves the transmission rate, increases the data length and ID length. In addition, compared with traditional wiring harnesses, optical fiber networks have lower energy consumption, lighter weight, faster transmission rate, lower latency, and larger signal volume.

[0060] Optionally, if the light-emitting components include entertainment components such as ambient lights and headrest screens, the first photoelectric conversion device can be connected to the switch of the corresponding light-emitting component. When a person in the predetermined area turns off the switch, the light is turned on to send a shutdown signal to the first photoelectric conversion device, which is transmitted to the corresponding light-emitting component via CANFD communication. The light-emitting component can be turned off to prevent the light-emitting component from lighting up the backlight and affecting the user.

[0061] In order to further reduce energy consumption, the detection element of the vehicle backlight adaptive adjustment control system of the present application also includes a light sensor for detecting the intensity of ambient light in a predetermined area. The light sensor is connected to the control device, and the control device adjusts the brightness value of the light-emitting component according to the received light intensity signal of the predetermined area. The brightness value of the light-emitting component can be subdivided into multiple gears through calibration, and the control device adjusts the brightness value of the light-emitting component to the corresponding gear according to the light intensity signal, thereby avoiding the light-emitting component from being continuously at a high brightness value, further reducing the power consumption of the light-emitting component.

[0062] Reference Figure 1A second photoelectric conversion device is provided between the light sensor and the detection element. The electrical signal emitted by the detection element is transmitted to the second photoelectric conversion device through CANFD communication. The second photoelectric conversion device converts the electrical signal into an optical signal and transmits it to the control device through the optical fiber network. Compared with CAN, CANFD increases the transmission rate, data length and ID length. In addition, compared with traditional wiring harnesses, optical fiber networks have lower energy consumption, lighter weight, faster transmission rate, lower latency and larger signal volume.

[0063] Optionally, if it is necessary to turn off the brightness value adjustment function of the light-emitting component, the second photoelectric conversion device can be connected to the switch of the light sensor. When the user turns off the switch, the light sensor can be turned off, thereby turning off the brightness value adjustment function of the light-emitting component to prevent the brightness value change of the light-emitting component from affecting the user.
