[0036] The implementation scheme of the present invention is described in detail below. This implementation scheme is implemented on the premise of the technical scheme of the present invention, and a detailed implementation method and specific operation process are given, but the protection scope of the present invention is not limited to the implementation scheme described below.

[0037] Figure 1 is a general block diagram of a cleaning system for vehicle interior according to an embodiment of the present invention. Figure 1 As shown, the cleaning system for the interior of a vehicle according to an embodiment of the present invention includes a sensor 10 , a controller 20 , a seat lifting device 30 , a floor cleaning device 40 , and an input device 50 .

[0038] The sensor 10 may be provided as at least one and configured to detect the running state of the vehicle and output corresponding state information. The controller 20 determines whether the vehicle is in a parking state according to the state information output by at least one sensor 10. For example, the sensor 10 may include an engine state sensor for detecting the engine state and a door lock state sensor for detecting the door lock state. When the engine state sensor outputs state information that the engine is turned off to the controller 20 and the door lock state sensor outputs state information that the door lock is locked to the controller 20, the controller 20 may determine that the vehicle is in a parking state according to the signals output by the engine state sensor and the door lock state sensor.

[0039] However, the sensor 10 of the present invention is not limited to the engine state sensor and the door lock state sensor, and the sensor 10 may also include a vehicle speed sensor, a gear position sensor, a pressure-type seat belt sensor, a seat sensor, etc., and whether the vehicle is in a parking state is determined by a combination of these sensors 10. For example, when the vehicle speed sensor detects that the vehicle speed is zero and the seat sensor 10 detects that no one is sitting, the controller 20 may determine that the vehicle is in a parking state.

[0040] According to an embodiment of the present invention, the floor cleaning device 40 is used to clean the floor of a vehicle. Figure 2 FIG. 2 shows a schematic diagram of a floor cleaning device according to an embodiment of the present invention placed in a storage space. Figure 2 As shown, a storage space 200 is provided below the rear seat 300 of the vehicle, and a floor cleaning device 40 is placed in the storage space 200 and is configured to be able to be moved out of the storage space 200 to clean the vehicle floor 100. Specifically, the floor cleaning device 40 may be a sweeping robot. The sweeping robot may move autonomously along a route, and during the movement, it may absorb ground debris into its own garbage storage box, thereby completing the function of floor cleaning.

[0041] In addition, a charging base 41 for the sweeping robot may be provided in the storage space 200. The charging base 41 is a charging device for the sweeping robot. When the sweeping robot finishes cleaning or when the power of the sweeping robot is low, it will automatically return to the storage space 200 and be charged in the charging base 41. Preferably, a cleaning pool (not shown) may also be provided in the charging base 41, so that the cleaning work of the two rotating mops at the bottom of the sweeping robot can be completed.

[0042] After the controller 20 determines that the vehicle is in a parking state, the controller 20 may control the floor cleaning device 40 to move out of the storage space 200 to clean the floor 100 of the vehicle. Figure 3 FIG. 1 is a schematic diagram showing a structure in which a floor cleaning device according to an embodiment of the present invention is moved out of a storage space. Figure 2 and Figure 3 The storage space 200 forms an opening, and an electric door 42 is provided at the opening. The controller 20 controls the electric door 42 to open before controlling the floor cleaning device 40 to move out of the storage space 200, and controls the electric door 42 to close after the floor cleaning device 40 returns to the storage space 200.

[0043] The floor 100 of the vehicle is almost flat, which is suitable for cleaning by a sweeping robot. However, the height between the seats other than the rear seats 300 and the floor may be insufficient, so that the floor cleaning device 40 cannot pass through, and the seats may hinder the cleaning of the floor cleaning device 40. Therefore, a seat lifting device 30 is provided in the cleaning system for the interior of the vehicle according to an embodiment of the present invention, and the seat lifting device 30 is used to lift at least the front seats of the vehicle. For example, in a vehicle with two rows of seats, the seat lifting device 30 is used to lift the front seats of the vehicle, and in a vehicle with three rows of seats, the seat lifting device 30 is used to lift the middle row seats and the front seats of the vehicle. In the following, a vehicle with two rows of seats is taken as an example. Figure 4 FIG. 2 shows a schematic diagram of a structure in which the front seats are raised according to an exemplary embodiment of the present invention. Figure 4 As shown, in a specific embodiment, the front seat 400 includes a lower base 410, which can be extended under the drive of the seat lifting device 30. After the base 410 is extended, the floor cleaning device 40 can clean the bottom of the front seat 400 and pass through the bottom of the front seat 400.

[0044] The controller 20 controls the seat lifting device 30 to at least raise the front seats 400 of the vehicle when the vehicle is in a parking state, and controls the floor cleaning device 40 to move out of the storage space 200 to clean the floor 100 of the vehicle.

[0045] The cleaning system for vehicle interior according to an embodiment of the present invention may further include an input device 50. The input device 50 can obtain user input. Specifically, the input device 50 can receive input related to various functions and / or operations of vehicle cleaning. The input device 50 may include an on / off button, a selection button, a physical button (such as a button for performing various functions), a slow dial and / or a touch pad. In addition, the input device 50 may include a touch screen that is integrated with the display.

[0046] The display may display information related to the operation of vehicle cleaning. In addition, the display may display a user interface (GUI) that can interact with the user. The display may include a touch screen and may receive touch input from the user. The display may convert the user's touch input into an electrical signal and send the electrical signal to the controller 20. The controller 20 may process the electrical signal according to the user's touch input and control the operation of the electric door 42, the floor cleaning device 40, and the seat lifting device 30 in response to the processing.

[0047] Specifically, the input device 50 may obtain a user input for turning on or off the cleaning function. The controller 20 may control the electric door 42, the floor cleaning device 40, and the seat lifting device 30 to operate based on the user input for turning on the cleaning function received from the input device 50, when it is determined that the vehicle is in a parking state. The controller 20 may not control the electric door 42, the floor cleaning device 40, and the seat lifting device 30 based on the user input for turning off the cleaning function received from the input device 50.

[0048] The controller 20 can perform overall control so that each device can perform functions normally. Such a controller 20 can be implemented in the form of hardware, can be implemented in the form of software, or can be implemented in the form of a combination thereof. The controller 20 can be formed integrally with the internal control unit of the vehicle, or can be implemented as a separate hardware device and connected to the control unit of the vehicle via a connection means. In the present embodiment, the controller 20 can be implemented by a vehicle-mounted head unit (HU).

[0049] In one embodiment, the input device 50 may be a touch screen integrated with the display in the HU, or a display in an audio, video, navigation and telematics (AVNT) system. The display in the HU may display an application (Application, APP) related to vehicle cleaning, and after the user operates the APP displayed on the touch screen, the display may display a user interface for vehicle cleaning. Figure 5 A schematic diagram of a user interface for vehicle cleaning displayed on a display in a HU is shown as an example. Figure 5 As shown, the user can select whether to turn on the cleaning function through the user interface. When the user selects "ON" on the user interface, the controller 20 can control the electric door 42, the seat lifting device 30 and the floor cleaning device 40 according to the user's touch input. On the contrary, when the user selects "OFF" on the user interface, the controller 20 does not control the electric door 42, the seat lifting device 30 and the floor cleaning device 40 according to the user's touch input.

[0050] In addition, the input device 50 may be further configured to obtain a user input of a cleaning start time, and the controller 20 may control the electric door 42, the floor cleaning device 40, and the seat lifting device 30 after the cleaning start time has passed since the vehicle is determined to be in a parked state, based on the user input of the cleaning start time received from the input device 50. Figure 5 As shown, the user can select the cleaning start time of the floor cleaning device 40 through the user interface. The user can select one of "3 minutes", "5 minutes" or "10 minutes" on the user interface. For example, the user selects "3 minutes" on the user interface. After three minutes have passed since the controller 20 determines that the vehicle is in a parking state, the controller 20 controls the electric door 42 to open, controls the floor cleaning device 40 to move out of the storage space 200 to clean the floor 100 of the vehicle, and controls the seat lifting device 30 to at least raise the front seat 400 of the vehicle. Therefore, the cleaning system according to the embodiment of the present invention can realize the reservation of the cleaning time, and the floor cleaning device 40 does not have to start cleaning immediately after the vehicle is parked every time.

[0051] Figure 6 1 is a timing chart of a cleaning process of a cleaning system for vehicle interior according to one embodiment of the present invention. Figure 6 As shown, the user selects to turn on the vehicle cleaning function through the input device 50 (i.e., the display of the HU), and at time T0, the vehicle cleaning is selected to be turned on. In order to park, the user first turns off the engine and uses the smart key to lock the door after getting off the vehicle. At this time, the controller 20 (specifically, the HU) can determine that the vehicle is in a parking state at time T1. Time T1 to time T2 is the above-mentioned cleaning start time. Starting from time T2, the HU controls the seat lifting device 30 to raise the front seat 400. At time T3, the front seat 400 rises to the maximum height. The time from time T2 to time T3 can be 5 seconds to 30 seconds. In addition, starting from time T2, the HU controls the electric door 42 to open, and controls the floor cleaning device 40 to move out of the storage space 200. From time T2 to time T4, the floor cleaning device 40 is in a working state of cleaning the floor. At time T4, the floor cleaning device 40 completes the cleaning of the floor and returns to the storage space 200. After time T4, the floor cleaning device 40 can be charged or self-cleaned at the charging base 41. Furthermore, at time T4, the HU controls the electric door 42 to close, controls the front seat 400 to start descending, and the front seat 400 will descend to the position before ascending (ie, the initial position).

[0052] Figure 7is a block diagram of a cleaning system for vehicle interior according to another embodiment of the present invention. In another embodiment, the input device 50 may be a touch screen integrated with a display of a remote control terminal 51. The remote control terminal 51 may include a smart phone, a PC, a laptop, etc. Figure 7 As shown, the cleaning system for vehicle interior according to the embodiment of the present invention may include a remote control server 80, which may be a telematics management service (TMS) center. The remote control server 80 enables communication between the remote control terminal 51 and the controller 20.

[0053] In particular, before the user starts a driving trip, the floor cleaning device 40 can be remotely turned on through a smart phone to clean the floor, so that the floor is clean when the user gets in the car. Since the doors and windows of the vehicle are usually closed when the vehicle is parked. If the vehicle is parked in the sun, the temperature inside the vehicle will rise, which may make the air quality inside the vehicle very poor. Therefore, it is also necessary for the vehicle user to clean the air inside the vehicle before getting in the vehicle to reduce the temperature inside the vehicle and discharge harmful gases.

[0054] Therefore, according to another embodiment of the present invention, the cleaning system for the interior of a vehicle further comprises an air cleaning device 60. The air cleaning device 60 is configured to supply air from the outside of the vehicle to the inside of the vehicle, thereby cleaning the air inside the vehicle. For example, the air cleaning device 60 may be an air conditioner. Figure 7 As shown, the controller 20 (specifically, HU) is electrically connected to the air cleaning device 60 and the seat lifting device 30 respectively through a central gateway (CGW) 70. The central gateway 70 enables the controller 20 to communicate with the air cleaning device 60 and the seat lifting device 30 respectively.

[0055] Similarly, the remote control terminal 51 (specifically, a smart phone) as the input device 50 can receive user input to turn on or off the cleaning function. When the controller 20 receives the user input to turn on the cleaning function from the remote control server 80, when it is determined that the vehicle is in a parking state, the controller 20 can control the electric door 42, the floor cleaning device 40, the seat lifting device 30, and the air cleaning device 60 to operate. When the controller 20 receives the user input to turn off the cleaning function from the remote control server 80, the controller 20 does not control the electric door 42, the floor cleaning device 40, the seat lifting device 30, and the air cleaning device 60.

[0056] In addition, the input device 50 (specifically, the remote control terminal 51) can be further configured to obtain the user's input of the target temperature in the vehicle and the user's input of the cleaning duration. The controller 20 (specifically, HU) can control the air cleaning device 60 to supply air to the interior of the vehicle so that the temperature in the vehicle reaches the target temperature in the vehicle based on the user input of the target temperature in the vehicle received from the input device 50 (specifically, the remote control terminal 51), while controlling the electric door 42, the floor cleaning device 40 and the seat lifting device 30. The controller 20 can control the floor cleaning device 40 to clean the vehicle floor within the cleaning duration based on the user input of the cleaning duration received from the input device 50 (specifically, the remote control terminal 51). Figure 8 A schematic diagram of a user interface for vehicle cleaning displayed on a smartphone is shown as an example. Figure 8 As shown, the user can select the in-vehicle temperature (ie, in-vehicle target temperature) and the operation maintenance time (ie, cleaning duration) on the user interface by dragging the progress bar.

[0057] Fig. 9 1 is a timing chart of a cleaning process of a cleaning system for vehicle interior according to one embodiment of the present invention. Fig. 9 As shown, from time T5 to time T6, the engine of the vehicle is turned off, the door locks are locked, and the vehicle is in a parking state. At time T6, the user chooses to start vehicle cleaning on the smartphone. Similar to the previous embodiment, from time T6, HU controls the seat lifting device 30 to raise the front seat 400, and at time T7, the front seat 400 rises to the maximum height, and the time from time T6 to time T7 can be in the range of 5 seconds to 30 seconds. In addition, from time T6, HU controls the electric door 42 to open, and controls the floor cleaning device 40 to move out of the storage space 200. From time T6 to time T8, the floor cleaning device 40 is in a working state of cleaning the floor. The time from time T6 to time T8 is the above-mentioned cleaning duration. The difference is that the cleaning system of this embodiment also includes an air cleaning device 60, which cleans the air inside the vehicle from time T6. In order to provide an energy source to the air cleaning device 60, at time T6, the engine is converted from a closed state to a started state. At time T8, the floor cleaning device 40 completes cleaning the floor and returns to the storage space 200. After time T8, the floor cleaning device 40 can be charged or self-cleaned at the charging stand 41. In addition, at time T8, the HU controls the engine to shut down, the air cleaning device 60 to shut down, the electric door 42 to close, and controls the front seat 400 to start descending, and the front seat 400 will descend to the position before the rise (i.e., the initial position).

[0058] An embodiment of the present invention also provides a method for cleaning the interior of a vehicle, the method comprising: at least one sensor 10 detecting the operating status of the vehicle and outputting corresponding status information; a controller 20 determining whether the vehicle is in a parking state based on the status information output by at least one sensor 10; when the controller 20 determines that the vehicle is in a parking state, the controller 20 controls the seat lifting device 30 to at least raise the front seat 400 of the vehicle, and at the same time, the controller 20 controls the floor cleaning device 40 to move out of the storage space 200 to clean the floor 100 of the vehicle.

[0059] Specifically, the engine status is detected by the engine status sensor, and the door lock status is detected by the door lock status sensor; the controller 20 determines whether the vehicle is in a parked state based on the engine status information output by the engine status sensor and the door lock status information output by the door lock status sensor.

[0060] The method further includes: before the controller 20 controls the floor cleaning device 40 to move out of the storage space 200, the controller 20 controls the electric door 42 at the opening of the storage space 200 to open; after the floor cleaning device 40 returns to the storage space 200, the controller 20 controls the electric door 42 to close, and controls the seat lifting device 30 to lower the front seat 400 of the vehicle to the position before the lifting.

[0061] The method further includes obtaining user input by the input device 50 , and controlling the electric door 42 , the floor cleaning device 40 , and the seat lifting device 30 by the controller 2 based on the user input received from the input device 50 .

[0062] Specifically, the input device 50 obtains the user's input for turning the cleaning function on or off. Based on the user input for turning on the cleaning function received by the controller 20 from the input device 50, the controller 20 controls the electric door 42, the floor cleaning device 40 and the seat lifting device 30 to operate when it determines that the vehicle is in a parked state. Based on the user input for turning off the cleaning function received by the controller 20 from the input device 50, the controller 20 does not control the electric door 42, the floor cleaning device 40 and the seat lifting device 30.

[0063] In one embodiment, the controller 20 is a vehicle host, and the input device 50 is a touch screen integrated with a display in the vehicle host. The input device 50 obtains a user input of the cleaning start time, and based on the user input of the cleaning start time received by the controller 20 from the input device 50, the controller 20 controls the electric door 42, the floor cleaning device 40, and the seat lifting device 30 to operate after determining that the vehicle is in a parking state and the cleaning start time has passed.
