Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.
It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The invention is applied to the vehicle, can realize the screen-off operation of the copilot display screen automatically when no passenger is in the copilot or the copilot has no passenger and passengers are in the rear row in the night driving process, and improves the operation convenience of the vehicle and the satisfaction degree of users.
Referring to fig. 1, the present invention provides a method for controlling a vehicle to turn off a screen, which in some embodiments may include the following steps:
and S10, detecting the illumination intensity outside the vehicle, and presetting an illumination intensity threshold value.
When the illumination intensity outside the vehicle is greater than or equal to the illumination intensity threshold, the copilot display screen may be turned on, and when the illumination intensity outside the vehicle is less than the illumination intensity threshold, the process may proceed to step S20.
And S20, detecting the seat bearing force of the front passenger seat and presetting a gravity threshold.
And when the bearing force of the seat is greater than or equal to the preset gravity threshold, the copilot display screen can be turned on.
When the seat bearing force is smaller than the preset gravity threshold, the process may proceed to step S30.
And S30, turning off the copilot display screen.
And S40, the loudspeaker can be driven to broadcast voice, and the instrument display screen can be used for prompting by characters.
By detecting the intensity of light outside the vehicle in step S10, and determining based on the detected intensity of light, it is possible to analyze whether the time zone outside the vehicle is in the daytime or at night. When a vehicle travels from one area to another area and when there is a time difference between the two areas, it may happen that one area is in the daytime and the other area is at night at the same time, and it is possible to analyze in real time whether the time zone outside the vehicle is in the daytime or at night by detecting the intensity of light outside the vehicle.
In some embodiments, the illumination intensity can be detected by a sunlight sensor, and when the illumination intensity is greater than 2800Lux and the duration is greater than 205 seconds in the case of entering the daytime from dawn, the daytime mode can be determined. When the tunnel enters the daytime, the illumination intensity is greater than 1500Lux, and the duration is greater than 5 seconds, the daytime mode can be judged. When the illumination intensity is less than 1000Lux and the duration is more than 2 seconds in the case of sudden dimming, the night mode can be judged. When the illumination intensity is less than 1200Lux and the duration is more than 205 seconds in the case of entering the evening from the daytime, the night mode can be determined.
The range of the sunlight sensor detection is, when the detected illumination intensity is greater than the illumination intensity threshold value X1(X1 may be set), that is, when the illumination intensity outside the vehicle is greater than the illumination intensity threshold value X1, and meanwhile, to prevent misjudgment, the duration of the value is also judged, if the duration of the illumination intensity outside the vehicle is greater than the illumination intensity threshold value X1 is greater than T1 (the value T1 may be set), for example, 5s may be set from the tunnel entrance daytime time T1, and 205s may be set from the dawn entrance daytime time T1, that is, both conditions are satisfied, the daytime mode is considered. Conversely, when the illumination intensity outside the vehicle is less than the illumination intensity threshold X2 and the duration that the illumination intensity outside the vehicle is less than the illumination intensity threshold X2 is greater than T2, the sudden dimming time of the sun light sensor is greater than T2 for 2s, or the duration from the daytime into the evening is greater than T2 for 205s, i.e. both conditions are met, the night mode is considered.
Step S20 detects the seat bearing force of the passenger seat, and determines whether or not the passenger seat has an occupant. When the seat bearing capacity of the passenger seat is greater than a preset gravity threshold, for example, the gravity threshold may be 400N, and when the seat bearing capacity of the passenger seat is greater than 400N, it is determined that the passenger seat has a passenger. Step S30 turns off the passenger display screen. In step S40, the speaker is driven to perform audio announcement, and the meter display screen performs text presentation.
When the outside illumination intensity of vehicle is less than the illumination intensity threshold value, and when the seat tolerance is less than when predetermineeing the gravity threshold value, satisfy night and the copilot does not have the passenger's the condition this moment, close the energy resource consumption that the copilot display screen can reduce whole car this moment. This situation may occur during night driving, and the passenger may need to take a rest and may actively select the rear area of the vehicle for riding. According to the invention, the copilot display screen is closed, so that when the problem that the copilot display screen is dazzled by light is solved, passengers in the rear row area of the vehicle are ensured to be in a comfortable rest environment, and the energy consumption of the whole vehicle can be reduced by closing the copilot display screen.
When the illumination intensity outside the vehicle is greater than or equal to the illumination intensity threshold value, the condition that the vehicle runs in the daytime is met, and the illumination of the copilot display screen cannot influence the passengers in the rear row, so that the copilot display screen can be in an open state at the moment.
When the illumination intensity outside the vehicle is smaller than the illumination intensity threshold value and the seat bearing capacity is larger than or equal to the preset gravity threshold value, the condition that the night time period is met and the passenger is in the copilot is met, and the copilot display screen can be in an open state at the moment in order to meet the requirement of the passenger in the copilot.
Referring to fig. 2, the present disclosure provides a method for controlling a vehicle to turn off a screen, which in some embodiments may include the following steps:
s101, detecting the illumination intensity outside the vehicle, and presetting an illumination intensity threshold value.
When the illumination intensity outside the vehicle is greater than or equal to the illumination intensity threshold, the copilot display screen may be turned on, and when the illumination intensity outside the vehicle is less than the illumination intensity threshold, the process may proceed to step S201.
S201, detecting the seat bearing capacity of the passenger seat, and presetting a gravity threshold.
When the seat bearing force is greater than or equal to the preset gravity threshold, the process may proceed to step S301.
When the seat bearing force is smaller than the preset gravity threshold, the process may proceed to step S401.
S301, judging whether the passenger in the copilot is at rest; when the passenger of the copilot is not at rest, the copilot display screen can be opened. When the passenger is at rest, step S401 may be entered.
S401, the copilot display screen can be closed.

Next, in step S201, whether there is a passenger in the passenger seat may be determined, and when the seat bearing force is smaller than the preset gravity threshold value and there is no passenger in the passenger seat, the passenger display screen is in an unattended state, and step S401 may be performed to turn off the passenger display screen. Step S201 may determine whether there is a passenger in the passenger seat, and when the seat bearing capacity is greater than or equal to the preset gravity threshold and there is a passenger in the passenger seat, step S301 may be performed. Then, step S301 may determine whether a passenger is at rest in the passenger compartment of the vehicle, and when the detected passenger is at rest in the passenger compartment of the vehicle, step S401 may be performed to turn off the passenger display screen in order to reduce interference of the passenger display screen with the passenger at rest in the passenger compartment of the vehicle. Step S301 may determine whether a passenger is at rest in the passenger compartment of the vehicle, and may turn on the passenger display screen to enable the passenger on the passenger display screen to view the passenger when the detected passenger is not at rest in the passenger compartment of the vehicle. In the step S401, the copilot display screen is closed, so that when the problem that the copilot display screen is dazzled in light illumination is solved, passengers in the rear row area of the vehicle are ensured to be in a comfortable rest environment, and the energy consumption of the whole vehicle can be reduced. In step S501, a speaker is driven to perform audio broadcasting, and a meter display screen performs text prompting.
When the illumination intensity outside the vehicle is smaller than the illumination intensity threshold value and when the seat bearing capacity is smaller than the preset gravity threshold value, and when the detected field of view of the rear row area of the vehicle is smaller than the preset field of view area threshold value, the night time period is met, and the situations that passengers do not exist in the copilot and the rear row of the vehicle are met, the illumination of the copilot display screen cannot be influenced, and therefore the copilot display screen can be in an open state at the moment.
