[0017] The following further details the specific embodiments of the present invention by describing the optimal embodiments with reference to the drawings.

[0018] The theme switching of the traditional vehicle host generally adopts the method described in the background technology. A function for switching themes is developed in the host, and then a physical or mechanical switch is set, and the artificial person switches different themes through the switch. Although this solution realizes the switchability of the theme, the switching still requires manual control. This solution provides a solution to realize automatic control to achieve automatic theme switching control.

[0019] Embodiment 1:

[0020] AsFigure 1 As shown, a control system for a vehicle host includes a host, a host display screen, an automatic / manual switch, a clock chip, and a light sensor. The host is connected to the host display screen and is configured to control the theme switching of the host display screen. The output end of the automatic / manual switch is connected to the host for inputting a theme control mode to the host. The output end of the clock chip is connected to the host for sending a time signal to the host. The light sensor is used to collect the in-vehicle ambient light intensity signal, and its output end is connected to the host. The output end of the host is connected to the backlight control unit of the host display screen.

[0021] The vehicle host is connected to the host display screen, enabling the vehicle host to drive and control the host display screen. The drive control includes functions such as controlling the data display, animation display, theme display, and switching of the display screen. The automatic / manual switch is a soft switch integrated in the host display screen, and the host display screen is a touch screen. The user can switch the theme mode to automatic or manual through the soft switch. The vehicle host enters the theme automatic switching mode or the host manual switching mode according to the signal of the switching switch. The manual switching mode is to manually input a switching signal to achieve the switching in the prior art, while the automatic mode is for the host to automatically switch and control according to the detected signal. The automatic switching signals include the time signal and the light intensity signal, corresponding to the clock chip and the light sensor in this solution. The clock chip is used to obtain the current time signal in real time and switch different themes corresponding to different times according to the time. For example, divided by day and night, select the theme corresponding to the day during the day and the theme corresponding to the night at night, and the division between day and night is distinguished according to the time signal. The light sensor is mainly used to collect the light intensity signal inside the vehicle, and its output end sends the light intensity signal to the vehicle host. The vehicle host adjusts the brightness of the display screen according to the strength of the light. The brightness adjustment of the host display screen is achieved through the backlight control unit, which is a built-in drive module of the display screen. In this solution, the vehicle host adjusts the backlight brightness of the host display screen according to the recognized in-vehicle light intensity, so as to better match the driving needs of the driver and improve the user experience.

[0022] Taking the switch between day and night as an example, when the time is between 6:00 am and 6:00 pm, it is judged as day, and at other times it is judged as night. Then, according to which time period the current time is in, the day or night at this time is judged, and the host switches the day theme or night theme accordingly. As for the backlight brightness of the display screen, it can be judged according to the value of the light sensor, and the backlight of the host display screen is adjusted according to the data of the light sensor. During the day, when the light value is between 1500 - 2000 Lux, the screen brightness is maintained at the default brightness of the host. When it is less than or equal to 1500 Lux, the screen brightness is controlled to decrease. Otherwise, when it is greater than 2000 Lux, the screen brightness is increased, and both the increase and decrease are achieved by the backlight control unit. Similarly, at night, when the light value is less than or equal to 1500 Lux, the screen brightness is maintained at the default brightness of the host. When it is greater than 1500 Lux, the backlight brightness is adjusted to increase, and the greater the light value, the higher the brightness.

[0023] Embodiment 2:

[0024] Based on Embodiment 1, this embodiment adds personalized switching control. Since Embodiment 1 can only achieve theme switching in two modes of day and night, but when there are multiple day themes or night themes, specific screening can be performed according to the personalized data of the driver at this time. For this, this solution provides two ways to switch personalized themes:

[0025] (1) Switching through the driver's mood

[0026] Obtaining the driver's mood includes a camera and a face recognition module. The camera is used to collect face image data, and the face recognition module is used to analyze and obtain the driver's mood state based on the face image data. Its output end is connected to the host, and the host switches the theme according to the driver's mood state. The camera can reuse the camera of the vehicle DMS system. The face recognition module runs a face recognition algorithm to analyze and obtain the driver's mood state data. For example, it can be divided into mood states such as sad, happy, and dull. The host switches to the theme corresponding to the mood in the day or night mode according to the driver's mood state sent by the face recognition module, so as to match the theme of the driver's mood state, realizing fast personalized theme matching control and meeting the needs of users.

[0027] (2) Switching by changing the vehicle speed

[0028] In addition to adjusting and controlling through the artificial mood, the switching of the theme can also be adjusted and controlled through driving conditions such as vehicle speed. Taking speed as an example, the driving condition is analyzed and judged based on the speed. The output end of the speed sensor is connected to the vehicle host, and the vehicle host controls the theme switching based on the vehicle speed change. If the vehicle speed changes little and the vehicle continues to drive at a constant speed, it is judged that the vehicle speed is relatively stable. If the vehicle speed fluctuates greatly and frequent occurrences such as sudden braking and rapid acceleration occur, it is judged that the vehicle speed fluctuates greatly. Then, the corresponding theme is switched and displayed under different vehicle speeds and different vehicle speed fluctuations, realizing the matching of different themes to different vehicle speed conditions, and achieving personalized switching of the vehicle host theme according to different driving vehicle speed changes.

[0029] Embodiment 3:

[0030] This embodiment provides a vehicle, which includes the control system of the vehicle host in Embodiment 1 or Embodiment 2. Since this vehicle includes all the features of the host control system in Embodiment 1, it has all the advantages of Embodiment 1 or 2, that is, the vehicle host theme can be switched according to parameters such as ambient light and driver state, meeting the personalized needs of users, improving the user experience, and the switching can be automatically performed, which is simple and reliable. In order to better adapt to the vehicle use environment, this solution controls the current screen display brightness according to the signal of the light sensor, reduces the light interference of the in-vehicle large screen on the driver when driving, and ensures the acquisition degree of driving-related information during driving, improving driving safety. The switching of the black and white mode theme is controlled according to the time setting, and the screen brightness adjustment is controlled in cooperation with the light sensor signal, and the theme is dynamically adjusted through face recognition data or vehicle speed data, which can give users a richer personalized experience and improve driving safety.

[0031] Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
