[0036] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0037] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0038] The present invention is applied to a vehicle and can automatically turn off the co-pilot display screen when there is no passenger in the co-pilot seat, or when there is no passenger in the co-pilot seat and there are passengers in the back row, thereby improving the operating convenience of the vehicle and the user's satisfaction.

[0039] See also Figure 1 The present invention proposes a method for controlling a vehicle screen off. In some embodiments, the method for controlling a vehicle screen off may include the following steps:

[0040] S10, detecting the light intensity outside the vehicle and presetting a light intensity threshold.

[0041] When the light intensity outside the vehicle is greater than or equal to the light intensity threshold, the co-pilot display screen can be turned on. When the light intensity outside the vehicle is less than the light intensity threshold, step S20 can be entered.

[0042] S20, detecting the bearing capacity of the front passenger seat and presetting a gravity threshold.

[0043] When the seat bearing force is greater than or equal to the preset gravity threshold, the co-pilot display screen can be turned on.

[0044] When the seat bearing force is less than the preset gravity threshold, step S30 may be entered.

[0045] S30, the co-pilot display screen can be turned off.

[0046] S40, can drive the speaker for voice broadcasting, and the instrument display screen can provide text prompts.

[0047] By detecting the light intensity outside the vehicle in step S10, it is possible to analyze whether the time period outside the vehicle is daytime or nighttime based on the detected light intensity. When a vehicle travels from one area to another, and when there is a time difference between the two areas, it may happen that one area is daytime while the other area is nighttime at the same time. By detecting the light intensity outside the vehicle, it is possible to analyze in real time whether the time period outside the vehicle is daytime or nighttime.

[0048] In some embodiments, the light intensity can be detected by a sunlight sensor. When the light intensity is greater than 2800 Lux and lasts for more than 205 seconds when entering daytime from dawn, it can be determined as daytime mode. When the light intensity is greater than 1500 Lux and lasts for more than 5 seconds when entering daytime from a tunnel, it can be determined as daytime mode. When it suddenly gets dark, the light intensity is less than 1000 Lux and lasts for more than 2 seconds, it can be determined as night mode. When the light intensity is less than 1200 Lux and lasts for more than 205 seconds when entering dusk from daytime, it can be determined as night mode.

[0049] The detection range of the sunlight sensor is as follows: when the detected light intensity is greater than the light intensity threshold X1 (X1 can be set), that is, when the light intensity outside the vehicle is greater than the light intensity threshold X1, in order to prevent misjudgment, the duration of this value must also be determined. If the duration of the light intensity outside the vehicle greater than the light intensity threshold X1 is greater than T1 (this value T1 can be set), for example, the time T1 from entering the daytime from the tunnel can be set to 5s, and the time T1 from entering the daytime from dawn can be set to 205s, that is, if both conditions are met at the same time, it is considered to be day mode. On the contrary, when the light intensity outside the vehicle is less than the light intensity threshold X2, and the duration of the light intensity outside the vehicle less than the light intensity threshold X2 is greater than T2, the sunlight sensor suddenly darkens for more than T2 2s, or the duration from daytime to dusk is greater than T2 205s, that is, both conditions are met, it is considered to be night mode.

[0050] Step S20 detects the bearing capacity of the front passenger seat to determine whether there is a passenger in the front passenger seat. When the bearing capacity of the front passenger seat is greater than a preset gravity threshold, for example, the gravity threshold may be 400N, when the bearing capacity of the front passenger seat is greater than 400N, it is determined that there is a passenger in the front passenger seat. Step S30 turns off the front passenger display screen. In step S40, the speaker is driven to broadcast sound, and the instrument display screen is prompted with text.

[0051] When the light intensity outside the vehicle is less than the light intensity threshold, and when the seat bearing force is less than the preset gravity threshold, it is night time and there is no passenger on the co-pilot seat. At this time, turning off the co-pilot display can reduce the energy consumption of the entire vehicle. This situation may occur during driving at night, when passengers need to rest and will actively choose to sit in the back row of the vehicle. The present invention solves the problem of glare from the co-pilot display by turning off the co-pilot display, ensuring that passengers in the back row of the vehicle are in a comfortable resting environment, and turning off the co-pilot display can also reduce the energy consumption of the entire vehicle.

[0052] When the light intensity outside the vehicle is greater than or equal to the light intensity threshold, the vehicle is driven during daytime hours. At this time, the light of the co-pilot display screen will not affect the rear passengers, so the co-pilot display screen can be turned on at this time.

[0053] When the light intensity outside the vehicle is less than the light intensity threshold, and when the seat bearing force is greater than or equal to the preset gravity threshold, it is during the night time period and there is a passenger on the front passenger seat. In order to meet the needs of the front passenger seat, the front passenger display screen can be turned on.

[0054] See also Figure 2The present invention proposes a method for controlling a vehicle screen off. In some embodiments, the method for controlling a vehicle screen off may include the following steps:

[0055] S101, detecting the light intensity outside the vehicle and presetting a light intensity threshold.

[0056] When the light intensity outside the vehicle is greater than or equal to the light intensity threshold, the co-pilot display screen can be turned on. When the light intensity outside the vehicle is less than the light intensity threshold, step S201 can be entered.

[0057] S201. Detect the bearing capacity of the front passenger seat and preset a gravity threshold.

[0058] When the seat bearing force is greater than or equal to the preset gravity threshold, the process proceeds to step S301.

[0059] When the seat bearing force is less than the preset gravity threshold, the process proceeds to step S401.

[0060] S301, determine whether the front passenger passenger is resting; when the front passenger passenger is not resting, the front passenger display screen can be turned on. When the front passenger passenger is resting, enter step S401.

[0061] S401. The co-pilot display screen can be turned off.

[0062] S501, the speaker can be driven for voice broadcasting, and the instrument display screen can provide text prompts.

[0063] First, step S101 can judge the light intensity outside the vehicle. When the light intensity outside the vehicle is less than a preset light intensity threshold, when the light intensity outside the vehicle belongs to the night time period and meets the above requirements, step S201 can be entered. Then, step S201 can judge whether there is a passenger in the co-pilot seat. When the seat bearing force is less than the preset gravity threshold, there is no passenger in the co-pilot seat, and the co-pilot display screen is in a state where no one is watching, step S401 can be entered to turn off the co-pilot display screen. Step S201 can judge whether there is a passenger in the co-pilot seat. When the seat bearing force is greater than or equal to the preset gravity threshold, there is a passenger in the co-pilot seat, step S301 can be entered. Then, step S301 can judge whether there is a passenger resting in the co-pilot area of ​​the vehicle. When the detected passenger in the co-pilot area of ​​the vehicle is resting, in order to reduce the interference of the co-pilot display screen on the rest of the passenger in the co-pilot area of ​​the vehicle, step S401 can be entered to turn off the co-pilot display screen. Step S301 can determine whether there are passengers resting in the co-pilot area of ​​the vehicle. When the detected passenger in the co-pilot area of ​​the vehicle is not resting, the co-pilot display screen can be turned on to allow the passenger on the co-pilot display screen to watch. In step S401, the co-pilot display screen is turned off to solve the problem of glare on the co-pilot display screen, ensure that the passengers in the rear area of ​​the vehicle are in a comfortable resting environment, and also reduce the energy consumption of the whole vehicle. In step S501, the speaker is driven to broadcast sound, and the instrument display screen is prompted with text.

[0064] When the light intensity outside the vehicle is less than the light intensity threshold and when the seat bearing force is less than the preset gravity threshold, and when the detected field of view of the rear area of ​​the vehicle is less than the preset field of view area threshold, the night time period is met and there are no passengers on the co-pilot seat and the back seat of the vehicle. At this time, the lighting of the co-pilot display screen will not be affected, so the co-pilot display screen can be in the turned-on state.

[0065] The light intensity outside the vehicle is detected by a sunlight sensor, and the seat bearing force of the front passenger seat is detected by a gravity sensor.

[0066] See also Figure 3 The present invention proposes a functional module diagram of a vehicle screen-off control system 100. In some embodiments, the vehicle screen-off control system 100 may include a sunlight sensor 110, a gravity sensor 111, a monitoring sensor 112, a control processor 113, an output device 114 and a co-pilot display screen 115.

[0067] The sunlight sensor 110 is used to detect the light intensity outside the vehicle.

[0068] The gravity sensor 111 is used to detect the seat bearing force of the front passenger seat.

[0069] The monitoring sensor 112 is used to monitor the field of view of the co-pilot area of ​​the vehicle.

[0070] The control processor 113 presets a light intensity threshold, a gravity threshold, and a visual field threshold. When the light intensity outside the vehicle is less than the light intensity threshold, the control processor 113 determines that it is night; when the seat bearing force is less than the gravity threshold, the control processor 113 determines that there is no passenger in the co-pilot seat; when the visual field of the co-pilot area of ​​the vehicle is greater than or equal to the visual field threshold, the control processor 113 determines that there is a passenger sleeping in the co-pilot area of ​​the vehicle.

[0071] The output device 114 is used to prompt the passenger to close the co-pilot display screen 115.

[0072] The control processor 113 controls to turn off the co-pilot display screen 115 when it is determined that the light intensity outside the vehicle is less than the light intensity threshold and the seat bearing force is less than the gravity threshold.

[0073] When the control processor 113 determines that the light intensity outside the vehicle is less than the light intensity threshold and the seat bearing force is greater than or equal to the gravity threshold, and when the field of view of the co-pilot area of ​​the vehicle is greater than or equal to the field of view area threshold, the co-pilot display screen 115 is controlled to be turned off.

[0074] Based on the signals collected by the sunlight sensor 110 and the gravity sensor 111 installed on the vehicle as input, it is determined whether the time period outside the vehicle is at night and whether there is a passenger in the front passenger seat. Combined with the in-car image information collected by the monitoring sensor 112 in the car, it is determined whether there are passengers in the rear area of ​​the vehicle. Finally, it is confirmed whether there are passengers on the front passenger seat of the car and whether the passengers in the front passenger area of ​​the vehicle are sleeping, and the information is input to the control processor 113 of the front passenger display screen, so as to intelligently control the output device 114 and the front passenger display screen 115, and feed back the control results to the customer. Finally, when there are passengers in the front passenger seat and the passengers in the front passenger area of ​​the vehicle are resting during driving at night, the front passenger display screen is turned off, thereby improving convenience and user satisfaction.

[0075] See also Figure 4The present invention proposes a vehicle screen-off control system 100. In some embodiments, the output device 114 may include a speaker 116 and an instrument display screen 117, wherein the speaker 116 gives a voice reminder to the driver, announcing "Dear user, in order not to affect your friend's rest / improve night driving safety, the co-pilot display screen 115 will be turned off", while reducing the volume of the vehicle audio. The instrument display screen 117 may prompt a text message, displaying "Dear user, in order not to affect your friend's rest / improve night driving safety, the co-pilot display screen 115 will be turned off".

[0076] To sum up, the present invention proposes a control method and system for turning off the vehicle screen. When passengers need to rest during driving at night, they will give up the co-pilot seat and choose to sit in the back seat of the vehicle. The present invention will turn off the co-pilot display screen, which solves the problem of glare from the co-pilot display screen and ensures that the co-pilot seat and passengers in the back seat of the vehicle are in a comfortable resting environment. Turning off the co-pilot display screen can also reduce the energy consumption of the entire vehicle.
