For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] An embodiment of the present invention provides a method for automatically adjusting the brightness of a vehicle-mounted display implemented by a terminal, wherein the terminal at least includes a CPU and the like.

[0044] Embodiment 1: Figure 1 A method for automatically adjusting the brightness of a vehicle display according to an exemplary embodiment includes:

[0045] Step 101 : when receiving brightness setting request data of the current user, obtaining the brightness percentage set by the current user in the brightness setting request data of the current user.

[0046] Step 102, obtaining the brightness percentage corresponding to the current illumination, and obtaining a new brightness percentage according to the brightness percentage currently set by the user, the brightness percentage corresponding to the current illumination, and the corresponding relationship data between the initial nonlinear ambient light illumination and the brightness percentage. The specific contents are as follows:

[0047] The brightness percentage corresponding to the illuminance when the user sets the brightness is obtained according to the corresponding relationship data of the current user-set brightness percentage and the initial nonlinear ambient light illuminance and the brightness percentage. The brightness percentage set by the current user, the brightness percentage corresponding to the illuminance when the user sets the brightness, and the brightness percentage corresponding to the illuminance when the user sets the brightness are obtained by formula (1) to obtain a new brightness percentage:

[0048]

[0049] Where: P 新 is the new brightness percentage, P 用户 The brightness percentage currently set by the user, P 照度 is the brightness percentage corresponding to the current illumination, P 用照 The brightness percentage corresponding to the illumination when the user sets the brightness.

[0050] Step 103, obtaining new nonlinear correspondence data of ambient light illumination and brightness percentage according to the new brightness percentage and the initial nonlinear correspondence data of ambient light illumination and brightness percentage, and automatically adjusting the brightness of the vehicle display according to the new nonlinear correspondence data of ambient light illumination and brightness percentage.

[0051] The following are some examples:

[0052] The corresponding relationship data of the initial nonlinear ambient light illumination and brightness percentage are as follows:

[0053] When the ambient light illumination is 0, the brightness percentage is 1%, when the ambient light illumination is 10, the brightness percentage is 5%, when the ambient light illumination is 100, the brightness percentage is 20%, when the ambient light illumination is 300, the brightness percentage is 50%, when the ambient light illumination is 1000, the brightness percentage is 80%.

[0054] When the current illuminance is 100, the brightness percentage corresponding to the current illuminance is 20%. When the user adjusts the brightness percentage to 50%, in the initial nonlinear corresponding relationship data of ambient light illuminance and brightness percentage, the ambient light illuminance corresponding to the brightness percentage of 50% is 300. The illuminance in the ambient light sensor remains unchanged, that is, when the current illuminance remains unchanged at 100, the corresponding brightness percentage is 50%. The new brightness percentage can be obtained by the above formula (1). According to the new brightness percentage and the initial nonlinear corresponding relationship data of ambient light illuminance and brightness percentage, the new nonlinear corresponding relationship data of ambient light illuminance and brightness percentage is obtained. According to the new nonlinear corresponding relationship data of ambient light illuminance and brightness percentage, the brightness of the vehicle display is automatically adjusted.

[0059] The control module 230 is used to obtain new nonlinear correspondence data between ambient light illumination and brightness percentage based on the new brightness percentage and the initial nonlinear correspondence data between ambient light illumination and brightness percentage, and automatically adjust the brightness of the vehicle display based on the new nonlinear correspondence data between ambient light illumination and brightness percentage.

[0060] Preferably, the calculation module 220 includes:

[0061] Obtaining the brightness percentage corresponding to the illumination when the user sets the brightness according to the brightness percentage currently set by the user and the corresponding relationship data between the initial nonlinear ambient light illumination and the brightness percentage;

[0062] A new brightness percentage is obtained according to the brightness percentage currently set by the user, the brightness percentage corresponding to the illumination when the user sets the brightness, and the brightness percentage corresponding to the illumination when the user sets the brightness.
