[0052] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0053] Figure 1 is a flowchart of a method for controlling display of a rear row of a vehicle provided by one or more embodiments of the present application.

[0054] As shown in Figure 1 the method for controlling display of a rear row of a vehicle comprises:

[0055] S1, detecting in real time a power state signal, a lock signal and an unlock signal of a vehicle;

[0056] S2, when it is detected that the power state of the vehicle is IG ON state, controlling the rear row display to keep a screen-on state; when it is detected that the power state of the vehicle is switched from IG ON to IG OFF state, judging whether a lock signal is received;

[0057] S3, if the power state of the vehicle is switched from IG ON to IG OFF state, judging whether a lock signal is detected;

[0058] if the lock signal is detected, controlling the rear row display to switch from a current screen-on state to an off state;

[0059] S4, before the rear row display executes the step S3 of switching the screen-on state of the rear row display to the off state, judging whether a signal for activating the power state of the vehicle from IG OFF state to IG ON state or an unlock signal is detected;

[0060] S5, if the signal for activating the power state of the vehicle from IG OFF state to IG ON state or the unlock signal is detected, the step S3 of switching the screen-on state to the off state is not executed.

[0061] Specifically, after the rear row display is controlled to switch from a current state to the off state, the space in the vehicle will lose light source, and if a passenger stays in the vehicle to use the rear row display device at this time, the passenger will be interrupted in the use state. Therefore, before the rear row display executes the step S3 of switching to the off state, it is judged whether a signal for activating the power state of the vehicle from IG OFF state to IG ON state or an unlock signal is detected, so as to ensure the continuity of use of the rear row passenger.

[0062] In the embodiment, before the rear row display executes the step S3 of switching the screen-on state of the rear row display to the off state, it is judged whether a signal for activating the power state of the vehicle from IG OFF state to IG ON state or an unlock signal is detected, comprising:

[0063] a first delay window is set;

[0064] the first delay window is started after the lock signal is detected, and it is determined whether a signal for activating the power state of the vehicle from the IG OFF state to the IG ON state or an unlock signal is detected during the first delay window;

[0065] If the first delay window is exceeded and the signal for activating the power state of the vehicle from the IG OFF state to the IG ON state or the unlock signal is not detected, the rear display is switched from the bright screen state to the screen-off state in step S3.

[0066] Specifically, the rear passengers need to rest and no longer need to use the rear display device. The demand state of the rear passengers for the rear display device can be confirmed through the first delay window. When the first delay window is exceeded and the signal for activating the power state of the vehicle from the IG OFF state to the IG ON state or the unlock signal is not detected, it is determined that the rear passengers no longer need to use the rear display device, and the rear display is switched from the bright screen state to the screen-off state.

[0067] In this embodiment, the signal for activating the power state of the vehicle from the IG OFF state to the IG ON state includes:

[0068] a touch instruction signal in the screen-off state of the rear display is detected;

[0069] If the touch instruction signal is detected, a signal for activating the power state of the vehicle from the IG OFF state to the IG ON state is generated.

[0070] Specifically, under normal circumstances, no one is in the vehicle after the vehicle is locked, and the touch instruction signal cannot occur. However, when the touch instruction signal is detected, it is considered that the person in the vehicle has a demand, and then the signal for activating the power state of the vehicle from the IG OFF state to the IG ON state is generated. At this time, the various subsystems can be more completely responsive to various instructions obtained from the touch screen.

[0071] In this embodiment, the signal for activating the power state of the vehicle from the IG OFF state to the IG ON state includes:

[0072] a second delay window is set;

[0073] If the rear display is switched from the bright screen state to the screen-off state in step S3, the second delay window is started, and it is determined whether a touch instruction signal in the screen-off state of the rear display is detected during the second delay window;

[0074] If the touch instruction signal is not detected, it is determined whether an unlock signal is detected;

[0075] If the unlock signal is detected, the rear display enters the bright screen state.

[0076] Specifically, maintaining the ability to detect touch instruction signals still requires some energy consumption. For the purpose of energy saving, it is not necessary to continuously wait for touch instruction signals in the off-screen state of the rear display. After the second delay window period, only the capture of the unlock signal is retained.

[0077] In this embodiment, it also includes step S6;

[0078] S6, after the rear display in step S3 enters the off-screen state, it is determined whether a signal for activating the power state of the vehicle from IG OFF state to IG ON state or an unlock signal is detected;

[0079] If a signal for activating the power state of the vehicle from IG OFF state to IG ON state or an unlock signal is detected, the rear display is controlled to enter the on-screen state from the off-screen state.

[0080] Specifically, step S6 replaces step S4, and the rear display enters the off-screen state first, reducing the risk of the vehicle being in an unsafe state due to waiting for too long a time. For example, during the on-screen period of the rear display, the inside of the cabin can be observed from the outside to determine whether there is any activity inside the cabin, whether there is any valuable left behind, etc. If there is no one inside the vehicle to take care of it and valuable is exposed, the risk of theft may increase (e.g., the vehicle is mistakenly believed to be not properly locked, at least increasing the possibility of theft attempts).

[0081] In this embodiment, it also includes:

[0082] If a signal for activating the power state of the vehicle from IG OFF state to IG ON state is detected and no unlock signal is detected, the rear display is controlled to enter the on-screen state and send a remote warning instruction.

[0083] Specifically, detecting a signal for activating the power state of the vehicle from IG OFF state to IG ON state and no unlock signal being detected includes leaving a child or pet in the rear seat, activating the rear display to enter the on-screen state by touching the screen as a kind of touch event that needs to be defended. Sending a remote warning instruction includes sending to a pre-stored, bound owner's mobile phone, or other public alarm phones, etc.

[0084] It needs to be particularly noted that the unlocking signal is equivalent to a signal that generally activates the power state of the vehicle from the IG OFF state to the IG ON state, and the signal generated by the rear seat display in the application by activating the touch screen to enter the bright screen state is not the same signal generation method and purpose, and the technical effect is different from the general unlocking signal. The unlocking signal is to open the access channel of the vehicle (the door), and then prepare for the person to enter the cabin to control the vehicle, and the power state of the vehicle is activated from the IG OFF state to the IG ON state. The application assumes that the person, pet is already in the vehicle, has no need or ability or right to unlock, but has the need or right to use or control the vehicle by means of the touch screen, and the service scene is that there is a person who can control the touch screen in the cabin, and the problem scene solved by the unlocking signal cannot be randomly mixed and understood.

[0085] Figure 2 It is a structural diagram of the automobile rear seat display control system provided by one or more embodiments of the application.

[0086] As Figure 2 shown, the automobile rear seat display control system comprises a signal monitoring module, a power state module, a screen control module, a state detection module, and a screen execution module.

[0087] The signal monitoring module is used to detect the power state signal, the lock signal, and the unlocking signal of the vehicle in real time.

[0088] The power state module is used to control the rear seat display to remain in the bright screen state when it is detected that the power state of the vehicle is in the IG ON state, and to determine whether the lock signal is received when it is detected that the power state of the vehicle is switched from the IG ON state to the IG OFF state.

[0089] The screen control module is used to determine whether the lock signal is detected when the power state of the vehicle is switched from the IG ON state to the IG OFF state.

[0090] If the lock signal is detected, the screen control module is used to control the rear seat display to switch from the current bright screen state to the off screen state.

[0091] The state detection module is used to determine whether the signal that activates the power state of the vehicle from the IG OFF state to the IG ON state or the unlocking signal is detected before the rear seat display switches from the bright screen state to the off screen state in step S3.

[0092] The screen execution module is used to not execute the switching from the bright screen state to the off screen state in step S3 if the signal that activates the power state of the vehicle from the IG OFF state to the IG ON state or the unlocking signal is detected.

[0093] It is worth noting that although the system / device only discloses the above signal monitoring module, power state module, screen control module, state detection module, screen execution module, but does not mean that the system / device is limited to the above basic function module, relatively, the meaning expressed by the present application is that on the basis of the above basic function module, the person skilled in the art can add one or more function modules to form infinite embodiments or technical solutions in combination with the prior art, that is, the system is open rather than closed, and the protection scope of the present application cannot be limited to the above disclosed basic function module because the present embodiment only discloses individual basic function module.

[0094] In one embodiment, an optimized screen-off logic is disclosed as shown in Figure 3 The traditional screen-off logic is designed according to the traditional instrument screen logic, and there is no lighting requirement when IG OFF. However, since the rear handrail screen exists in the working condition when IG OFF, the screen cannot be turned off directly when IG OFF. In order to save the vehicle power after the vehicle is locked and the user leaves, the screen needs to be turned off directly after the vehicle is locked. Since the scenario that the user rests in the vehicle after the vehicle is locked is not considered in the initial design, the working condition that the vehicle is directly turned on without unlocking after the vehicle is locked is ignored. Therefore, in the related screen-off logic designed, IG ON and unlocking are in series, which causes that the vehicle is directly turned on after the vehicle is locked, resulting in abnormal logic and the screen cannot be normally turned on.

[0095] In one embodiment, an optimized screen-off logic is disclosed as shown in Figure 4 Based on the improvement of Figure 3 , the parallel logic of IG ON and unlocking is changed from the original series logic, the robustness of the scheme is expanded, and the optimized screen-off logic can cover more special working conditions to avoid occasional logic errors or abnormalities.
