Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] Embodiment 1

[0060] Please refer to Figure 1 , is a flowchart of a method for adjusting intelligent cockpit lighting provided by an embodiment of the present invention, including steps S101 to S105.

[0061] Step S101: Acquire a lighting adjustment instruction, identify the lighting adjustment instruction, and obtain a target scene mode and a target color tone style for lighting adjustment.

[0062] In this embodiment, the user or driver can input lighting adjustment instructions to the smart cockpit through the touch screen, physical buttons, voice control, gesture recognition, etc. in the vehicle cockpit. The smart cockpit can obtain the target scene mode and target color tone style of the lighting adjustment by identifying the lighting adjustment instructions.

[0063] In this embodiment, the lighting adjustment instruction can also be obtained through the vehicle navigation information of the smart cockpit. The future road condition of the vehicle is obtained based on the vehicle navigation information of the smart cockpit; then the future road condition is matched with the historical lighting adjustment data stored in the smart cockpit to obtain the lighting adjustment instruction. Among them, the historical lighting adjustment data stores the historical lighting adjustment instructions corresponding to each historical road condition; the future road condition of the vehicle can be set to the road condition of the vehicle traveling 10 km in the future, and can also be set to the road condition of the vehicle traveling 30 minutes in the future.

[0064] Furthermore, the future road condition is matched with each historical road condition for similarity, and the historical road condition with the highest similarity and its corresponding first historical light adjustment instruction are screened out, and the first historical light adjustment instruction is used as the light adjustment instruction of the smart cockpit.

[0065] It should be noted that the target scene modes described in this embodiment include: sun shading mode, makeup mode, shooting mode and live broadcast mode; in the makeup mode, shooting mode and live broadcast mode, the target color tone style includes: standard style, warm color tone style and cool color tone style; the standard style is the default color tone style of the makeup mode, shooting mode and live broadcast mode.

[0066] In an optional embodiment, the sunshade mode of the vehicle smart cockpit can be achieved by installing dimmable glass or blackout curtains on the vehicle. The default mode of the vehicle smart cockpit is set to normal mode, that is, the light transmittance of the vehicle glass is bright or the blackout curtain is closed, and the lights in the vehicle are turned off.

[0067] In an optional embodiment, the vehicle's smart cockpit is configured to obtain the current outdoor light intensity through a light sensor installed on the vehicle window glass in normal mode. When the outdoor light intensity is greater than a preset light intensity threshold, the vehicle's smart cockpit automatically turns on the sunshade mode.

[0068] Step S102: obtaining a light intensity reference value and a color temperature reference value according to the target scene mode and the target adjustment style.

[0069] Step S103: Divide the smart cockpit into regions to obtain a number of cockpit regions, and collect the measured light intensity and the measured light color temperature of each cockpit region.

[0070] In this embodiment, the smart cockpit is divided into several cockpit areas, and the measured light intensity and the measured light color temperature of each cockpit area are collected, specifically including:

[0071] Dividing the smart cockpit into regions to obtain a plurality of cockpit regions, wherein the plurality of cockpit regions include: a first cockpit region and a second cockpit region;

[0072] respectively obtaining light intensity information and light color temperature information of the first cockpit area and the second cockpit area;

[0073] The light intensity information and the light color temperature information are preprocessed according to a preset light information preprocessing strategy to obtain the measured light intensity and the measured light color temperature of each cabin area.

[0074] In an optional embodiment, the interior space of the smart cockpit is divided into two areas, front and rear, to obtain a front area (i.e., a first cockpit area) and a rear area (i.e., a second cockpit area), and the measured light intensity and measured light color temperature of the front and rear areas are obtained by installing ambient light sensors in the front and rear areas of the vehicle.

[0075] Specifically, an ambient light sensor is installed in the front area and the rear area respectively, which collects light information data in the cabin within a specified time at a certain frequency (which can be set through the smart cockpit or maintain the default collection frequency).

[0076] This embodiment divides the smart cockpit into areas to obtain light intensity information and light color temperature information for each cockpit area. By dividing the smart cockpit, a more accurate external light environment can be obtained, thereby achieving more accurate lighting adjustment and meeting different light adjustment requirements for the smart cockpit.

[0077] In this embodiment, the light intensity information and the light color temperature information are preprocessed according to a preset light information preprocessing strategy to obtain the measured light intensity and the measured light color temperature of each cabin area, specifically including:

[0078] Eliminating the maximum value and the minimum value in the light intensity information, and extracting the median of the light intensity in the eliminated light intensity information to obtain the measured light intensity of each cabin area;

[0079] The maximum value and the minimum value in the light color temperature information are eliminated, and the median color temperature in the eliminated light color temperature information is extracted to obtain the measured light color temperature of each cabin area.

[0080] This embodiment preprocesses the light intensity information and the light color temperature information to obtain the measured light intensity and the measured light color temperature that can accurately characterize the external light environment, thereby achieving more accurate light adjustment and meeting different light adjustment requirements for the smart cockpit.

[0081] Step S104: determining the light intensity adjustment value and the color temperature adjustment value of each cabin area according to the measured light intensity, the measured light color temperature, the light intensity reference value and the color temperature reference value.

[0082] In this embodiment, determining the light intensity adjustment value and the color temperature adjustment value of each cabin area according to the measured light intensity, the measured light color temperature, the light intensity reference value and the color temperature reference value specifically includes:

[0083] Acquire the in-vehicle configuration information and the in-vehicle lighting status, and determine the light intensity calculated value and the color temperature calculated value of each cabin area in combination with the measured light intensity, the measured light color temperature, the light intensity reference value and the color temperature reference value;

[0084] Calibrate the mapping relationship between the light intensity calculated value, the color temperature calculated value and the preset light adjustment coefficient based on the preset database, and determine the light intensity adjustment value corresponding to the light intensity calculated value and the color temperature adjustment value corresponding to the color temperature calculated value according to the mapping relationship;

[0085] The database is queried to determine a light intensity adjustment value and a color temperature adjustment value for each cabin area based on the light intensity calculation value and the color temperature calculation value for each cabin area.

[0086] This embodiment determines the light intensity calculation value and the color temperature calculation value through the measured light intensity, the measured light color temperature, the light intensity reference value and the color temperature reference value, thereby realizing the combination of the measured light environment and the target light environment. It not only takes into account the light adjustment requirements, but also fully considers the impact of the external light environment on the smart cockpit lighting under different driving environments. The mapping relationship between the light intensity calculation value, the color temperature calculation value and the preset light adjustment coefficient is established through the database, and the light intensity adjustment value and the color temperature adjustment value are determined, thereby further improving the accuracy of the smart cockpit lighting adjustment.

[0087] In this embodiment, after determining the light intensity adjustment value and the color temperature adjustment value of each cabin area according to the measured light intensity, the measured light color temperature, the light intensity reference value and the color temperature reference value, the method further includes:

[0088] When the target scene mode is the preset first scene mode, obtaining clothing color information of passengers in the vehicle;

[0089] The light intensity adjustment value and the color temperature adjustment value are updated according to the clothing color information.

[0090] In an optional embodiment, the first scene mode is preset as a shooting mode. When the target scene mode is the shooting mode, the user in the car takes pictures with clothes of different colors. In order to achieve a better shooting effect, the color information of the clothes of the passengers in the car is obtained through a camera installed in the car.

[0091] This embodiment updates the light intensity adjustment value and the color temperature adjustment value of the preset first scene mode by combining the clothing color information of the passengers in the car, so that the light adjustment effect of the preset first scene mode is more accurate.

[0092] In this embodiment, the acquisition of the in-vehicle configuration information and the in-vehicle lighting status, and the determination of the light intensity calculation value and the color temperature calculation value of each cabin area in combination with the measured light intensity, the measured light color temperature, the light intensity reference value and the color temperature reference value specifically include:

[0093] Acquire the in-vehicle configuration information and the in-vehicle lighting status, wherein the in-vehicle configuration information includes: the total area of ​​the in-vehicle space, the height from the roof to the vehicle seat, the area of ​​the luminous area, and the total area of ​​the light-transmitting component;

[0094] According to the lighting status in the vehicle, the lighting calculation ratio coefficient is determined by combining the total area of ​​the vehicle interior space, the height from the roof to the vehicle seat, the area of ​​the luminous area and the total area of ​​the light-transmitting parts;

[0095] Calculate the proportionality coefficient and the in-vehicle lighting state based on the lighting, construct a functional relationship between the measured light intensity and the reference value of the light intensity through the database, and determine the calculated value of the light intensity for each cockpit area;

[0096] Calculate the proportionality coefficient and the in-vehicle lighting state based on the lighting, construct a functional relationship between the measured color temperature of the light and the reference value of the color temperature through the database, and determine the calculated value of the color temperature for each cockpit area.

[0097] In an alternative embodiment, the total area of the in-vehicle space is set to s, the height from the roof to the vehicle seat is set to h, the area of the light-emitting area is set to u, the total area of the light-transmitting components is set to w, the measured light intensity is Q0, the measured color temperature of the light is K0, and the reference value of the light intensity is set to Q p , and the reference value of the color temperature is set to K p .

[0098] When the in-vehicle lighting is not turned on, the calculated value of the light intensity = (Q p - Q0) * a, and the calculated value of the color temperature = (K p - K0) * a, where a is the proportionality coefficient of the lighting when the in-vehicle lighting is not turned on, and the calculation formula of a is

[0099] When the in-vehicle lighting is turned on, if Q p > Q0, at this time the calculated value of the light intensity = (Q p - Q0) * b; if Q p < Q0, at this time the calculated value of the light intensity = (Q0 - Q p ) * (1 / b); if K p > K0, at this time the calculated value of the color temperature = (K p - K0) * b; if K p < K0, at this time the calculated value of the color temperature = (K0 - K p ) * (1 / b); where b is the proportionality coefficient of the lighting when the lighting is turned on, and the calculation formula of b is

[0100] After obtaining the calculated value of the light intensity and the calculated value of the color temperature, establish a one-to-one mapping relationship between the preset lighting adjustment coefficient, the calculated value of the light intensity, and the calculated value of the color temperature based on the database, and determine the light intensity adjustment value and the color temperature adjustment value; among them, the specific mapping relationship can be calibrated by those skilled in the art according to the specific experimental environment or vehicle environment based on experiments to obtain the best mapping relationship, and the present invention will not elaborate too much here.

[0101] In an alternative embodiment, when the target scene mode is the shooting mode, it is necessary to further update based on the light intensity calculated value and the color temperature calculated value of the clothing color of the passengers.

[0102] In an optional embodiment, a database retrieval system is constructed to quickly and accurately determine the calculated light intensity and color temperature values. Specifically, the color temperature value of the warm color style is the color temperature reference value plus the fixed color temperature value; the color temperature value of the cold color style is the color temperature reference value minus the fixed color temperature value; the fixed color temperature value can be adjusted by the passengers or users through the smart cockpit.

[0103] This embodiment determines the lighting calculation ratio coefficient through the in-vehicle configuration information and the in-vehicle lighting status, and determines the light intensity calculation value and the color temperature calculation value through the database; by integrating the real-time in-vehicle configuration information, lighting adjustment requirements and the external lighting environment, the accuracy of the light intensity calculation value and the color temperature calculation value is improved.

[0104] Step S105: adjusting the smart cockpit to the target scene mode according to the preset scene mode adjustment strategy, and adjusting the light intensity and color temperature of the lights in each cockpit area based on the light intensity adjustment value and the color temperature adjustment value in combination with the target color tone style to complete the adjustment of the smart cockpit lights.

[0105] In this embodiment, the smart cockpit is adjusted to the target scene mode according to the preset scene mode adjustment strategy, and the light intensity and color temperature of the light in each cockpit area are adjusted based on the light intensity adjustment value and the color temperature adjustment value in combination with the target color tone style to complete the adjustment of the smart cockpit light, specifically including:

[0106] Determine a target operation object and a target state of the target operation object according to the target scene mode;

[0107] According to a preset scene mode adjustment strategy, the smart cockpit is adjusted to the target scene mode in combination with the target operation object corresponding to the target scene mode and the target state of the target operation object;

[0108] The database is queried to obtain a corrected color temperature value of the target color tone style, and the light intensity and color temperature of the light in each cabin area are adjusted according to the corrected color temperature value, the light intensity adjustment value, and the color temperature adjustment value to complete the adjustment of the smart cabin light.

[0109] In this embodiment, the smart cockpit is adjusted to the target scene mode according to the preset scene mode adjustment strategy, in combination with the target operation object corresponding to the target scene mode and the target state of the target operation object, specifically including:

[0110] The target operation objects include: smart cockpit glass, blackout curtains, seats and lights; the target states of the smart cockpit glass include: bright state and dark state; the target states of the blackout curtains and lights include: open state and closed state; the target state of the seats includes: seat position;

[0111] After the smart cockpit glass or blackout curtain is adjusted to the corresponding target state, the seat and each light in the smart cockpit are adjusted to their respective corresponding target states to adjust the smart cockpit to the target scene mode.

[0112] In this embodiment, the querying of the database to obtain the corrected color temperature value of the target color tone style, and adjusting the light intensity and color temperature of the light in each cabin area according to the corrected color temperature value, the light intensity adjustment value, and the color temperature adjustment value to complete the adjustment of the smart cabin light specifically includes:

[0113] Querying the database to identify the corrected color temperature value of the target color tone style;

[0116] In an optional embodiment, the scene mode and interior lighting control of the smart cockpit can be divided into two situations. The first situation is to turn on the makeup mode, shooting mode and live broadcast mode in the normal mode, and the second situation is to turn on the makeup mode, shooting mode and live broadcast mode in the sunshade mode.

[0117] Specifically, the makeup mode is to turn on the makeup mirror light of the driver or passenger seat, and adjust the seat forward to a suitable makeup position.

[0118] The live broadcast mode turns on the vehicle ceiling lights in the corresponding area (i.e., the front row area or the rear row area), including the ceiling lights in at least one area of ​​the front row area or the rear row area. When the vehicle is equipped with left front, right front, left rear and right rear side ceiling lights, the front row area in the live broadcast mode turns on the front ceiling lights, left front and right front side ceiling lights; the rear row area in the live broadcast mode turns on the rear ceiling lights, left rear and right rear side ceiling lights, and adjusts the seat to the memory position of the live broadcast mode (the memory position can be determined based on the historical seat adjustment conditions stored in the smart cockpit).

[0119] The shooting mode is to turn on all the vehicle's roof lights, including the front and rear roof lights. If the vehicle is equipped with left front, right front, left rear and right rear side roof lights, turn on the left front, right front, left rear and right rear side roof lights at the same time. At this time, the position of the passengers is identified through the in-car camera. If there is no one in the back row of the passengers, the seat is adjusted back to the maximum position.

[0120] In an optional embodiment, if the current mode is in the makeup mode under the normal mode, the user inputs a light adjustment command, and the light adjustment command is recognized as adjusting to the shooting mode under the sunshade mode.
