Description

Technical Field

[0001] This invention relates to the field of vehicle application technology, and in particular to a vehicle anti-ear system, method and vehicle. Background Technology

[0002] When a vehicle door is closed, if the interior windows are also closed, a sealed space is created. When the door closes, it draws a large amount of air into the passenger compartment in a very short time. Due to the vehicle's airtight design, the drawn-in air cannot escape quickly enough, causing compression within the passenger compartment and a sudden increase in pressure. This sudden pressure change acts on the eardrums, causing them to deform and resulting in discomfort and a noticeable "ear pressure" sensation. The passenger compartment of a car is a relatively closed system. To ensure a good driving and riding environment, reduce NVH noise, and improve air conditioning efficiency, modern cars have increasingly higher levels of airtightness. This improved airtightness is a major cause of ear pressure problems when doors close. Related research indicates that a higher door closing angular velocity, the absence of a pressure relief device, the closure of the same-side door window, and a larger ratio of door area to passenger compartment volume all contribute to ear pressure phenomena. Summary of the Invention

[0003] To address the aforementioned problems, the inventors have developed this invention, which, through specific embodiments, provides a vehicle anti-ear system, method, and vehicle.

[0004] In a first aspect, embodiments of the present invention provide a vehicle anti-pinch ear system, comprising:

[0005] Rainfall sensing unit, used to acquire and transmit rainfall information;

[0006] The door opening sensor unit is used to acquire and send door opening and closing status information;

[0007] The occupant number sensing unit is used to acquire and send information on the number of occupants inside the vehicle;

[0008] The window status sensing unit is used to acquire and send window opening / closing status information;

[0009] The sunroof status sensing unit is used to acquire and send sunroof opening and closing status information;

[0010] The gear position sensing unit is used to acquire and send vehicle gear position status information;

[0011] The control unit is used to receive the information sent by the aforementioned sensing unit, perform monitoring cycles, and send control commands to the window actuator unit according to the preset control logic and the information sent by the aforementioned sensing unit.

[0012] The window actuator is used to receive control commands from the control unit and, according to the control commands, execute the opening or closing of the corresponding window.

[0013] Specifically, the control unit determines whether it is raining based on the received rainfall information and a preset rainfall threshold.

[0014] Specifically, the occupant quantity sensing unit includes:

[0015] Vehicle-mounted visual sensing devices are used to acquire and transmit information on the number of occupants inside the vehicle;

[0016] and / or

[0017] Seat pressure sensors are used to acquire and transmit information about the number of occupants in the vehicle.

[0018] Specifically, when the occupant quantity sensing unit includes both an in-vehicle vision sensing device and a seat pressure sensing device, the occupant quantity sensing unit compares the occupant quantity information obtained by the in-vehicle vision sensing device and the seat pressure sensing device. The occupant quantity information includes the number of occupants and the corresponding accuracy. When the number of occupants obtained by the in-vehicle vision sensing device and the seat pressure sensing device are consistent, the occupant quantity sensing unit sends the consistent number of occupants. When the number of occupants obtained by the in-vehicle vision sensing device and the seat pressure sensing device are inconsistent, the occupant quantity sensing unit sends the occupant quantity with higher accuracy.

[0019] Specifically, the control unit is used for:

[0020] The opening positions of all doors and windows are obtained from the door opening and closing status information, and the memory positions of all doors and windows are obtained.

[0021] When all car doors are detected to be closed, the first state judgment is performed; when not all car doors are detected to be closed, the next monitoring cycle begins.

[0022] The first state is that the gear is in P gear, it is not raining, the number of occupants in the vehicle is not less than 2, and the sunroof opening position is between the preset sunroof opening position and the sunroof fully closed position.

[0023] Based on vehicle gear status information, rainfall information, number of occupants in the vehicle information, and sunroof opening / closing information, a first state judgment is made. When the vehicle is in the first state, a second state judgment is made. When the vehicle is not in the first state, the next monitoring cycle begins.

[0024] The second state is when any door is open;

[0025] The system monitors the door opening status and makes a second-state judgment. When the vehicle is in the second state, it makes a third-state judgment. When the vehicle is not in the second state, the next monitoring cycle begins.

[0026] The third state is when the window opening position of the open door is not between the preset window opening position and the window fully open position;

[0027] The system monitors the opening position of the car window when the car door is open and makes a third state judgment. When the vehicle is in the third state, it monitors the state of the open door and controls the window of the open door to open to the preset window opening position before the open door closes. When it detects that the open door is in the closed state, it controls the window of the open door to return to the memory position corresponding to the open door.

[0028] When the vehicle is not in the third state, the open door window remains in its current position, the status of the open door is monitored, and when the open door is detected to be in the closed state, the next monitoring cycle begins.

[0029] Specifically, based on the vehicle model, pressure ear analysis is performed to determine the preset window opening position and the preset sunroof opening position.

[0030] Secondly, embodiments of the present invention provide a method for preventing vehicle pressure ears, comprising the following steps:

[0031] The number of occupants inside the vehicle is determined using an occupant quantity sensing unit;

[0032] Obtain the opening positions of all doors and windows from the door opening and closing status information, and get the memory positions of all doors and windows;

[0033] When all car doors are detected to be closed, the first state judgment is performed; when not all car doors are detected to be closed, the next monitoring cycle begins.

[0034] The first state is that the gear is in P gear, it is not raining, the number of occupants in the vehicle is not less than 2, and the sunroof opening position is between the preset sunroof opening position and the sunroof fully closed position.

[0035] Based on vehicle gear status information, rainfall information, number of occupants in the vehicle information, and sunroof opening / closing information, a first state judgment is made. When the vehicle is in the first state, a second state judgment is made. When the vehicle is not in the first state, the next monitoring cycle begins.

[0036] The second state is when any door is open;

[0037] The system monitors the door opening status and makes a second-state judgment. When the vehicle is in the second state, it makes a third-state judgment. When the vehicle is not in the second state, the next monitoring cycle begins.

[0038] The third state is when the window opening position of the open door is not between the preset window opening position and the window fully open position;

[0039] The system monitors the opening position of the car window when the car door is open and makes a third state judgment. When the vehicle is in the third state, it monitors the state of the open door and controls the window of the open door to open to the preset window opening position before the open door closes. When it detects that the open door is in the closed state, it controls the window of the open door to return to the memory position corresponding to the open door.

[0040] When the vehicle is not in the third state, the open door window remains in its current position, the status of the open door is monitored, and when the open door is detected to be in the closed state, the next monitoring cycle begins.

[0041] Specifically, the number of occupants in the vehicle is determined using an occupant quantity sensing unit, including the following steps:

[0042] When the occupant quantity sensing unit includes both an in-vehicle vision sensing device and a seat pressure sensing device, the occupant quantity sensing unit compares the occupant quantity information obtained by the in-vehicle vision sensing device and the seat pressure sensing device. The occupant quantity information includes the number of occupants and the corresponding accuracy. When the number of occupants obtained by the in-vehicle vision sensing device and the seat pressure sensing device is consistent, the occupant quantity sensing unit sends the consistent number of occupants. When the number of occupants obtained by the in-vehicle vision sensing device and the seat pressure sensing device is inconsistent, the occupant quantity sensing unit sends the number of occupants with higher accuracy.

[0043] Specifically, the vehicle anti-pinch ear method further includes the following steps:

[0044] Based on the vehicle model, pressure ear analysis was performed to determine the preset window opening position and the preset sunroof opening position;

[0045] Based on the obtained rainfall information and the preset rainfall threshold, it is determined whether it is raining.

[0046] Based on the same inventive concept, embodiments of the present invention also provide a vehicle, including the vehicle anti-pinch system as described above, or a window opening strategy designed using the vehicle anti-pinch method as described above.

[0047] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:

[0048] This invention provides a scene-based recognition and intelligent control of window opening to eliminate the confined space inside the vehicle and solve the problem of ear pressure for passengers when the doors are closed, taking into account weather conditions.

[0049] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

[0054] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0055] To address the problems existing in the prior art, embodiments of the present invention provide a vehicle anti-ear system, method, and vehicle.

[0056] This invention provides a vehicle anti-pinch ear system, comprising:

[0057] Rainfall sensing unit, used to acquire and transmit rainfall information;

[0058] The door opening sensor unit is used to acquire and send door opening and closing status information;

[0059] The occupant number sensing unit is used to acquire and send information on the number of occupants inside the vehicle;

[0060] The window status sensing unit is used to acquire and send window opening / closing status information;

[0061] The sunroof status sensing unit is used to acquire and send sunroof opening and closing status information;

[0062] The gear position sensing unit is used to acquire and send vehicle gear position status information;

[0063] The control unit is used to receive the information sent by the aforementioned sensing unit, perform monitoring cycles, and send control commands to the window actuator unit according to the preset control logic and the information sent by the aforementioned sensing unit.

[0064] The window actuator is used to receive control commands from the control unit and, according to the control commands, execute the opening or closing of the corresponding window.

[0065] Specifically, the control unit determines whether it is raining based on the received rainfall information and a preset rainfall threshold.

[0066] Specifically, the occupant quantity sensing unit includes:

[0067] Vehicle-mounted visual sensing devices are used to acquire and transmit information on the number of occupants inside the vehicle;

[0068] and / or

[0069] Seat pressure sensors are used to acquire and transmit information about the number of occupants in the vehicle.

[0070] Specifically, when the occupant quantity sensing unit includes both an in-vehicle vision sensor and a seat pressure sensor, the occupant quantity sensing unit compares the occupant quantity information acquired by the in-vehicle vision sensor and the seat pressure sensor. This occupant quantity information includes the number of occupants and their corresponding accuracy. If the number of occupants acquired by the in-vehicle vision sensor and the seat pressure sensor is the same, the occupant quantity sensing unit sends the consistent occupant quantity. If the number of occupants acquired by the in-vehicle vision sensor and the seat pressure sensor is inconsistent, the occupant quantity sensing unit sends the occupant quantity with higher accuracy. When the occupant quantity sensing unit includes only an in-vehicle vision sensor or a seat pressure sensor, the occupant quantity sensing unit sends the occupant quantity provided by the corresponding sensor.

[0071] Specifically, the control unit is used for:

[0072] The opening positions of all doors and windows are obtained from the door opening and closing status information, and the memory positions of all doors and windows are obtained.

[0073] When all car doors are detected to be closed, the first state judgment is performed; when not all car doors are detected to be closed, the next monitoring cycle begins.

[0074] The first state is that the gear is in P gear, it is not raining, the number of occupants in the vehicle is not less than 2, and the sunroof opening position is between the preset sunroof opening position and the sunroof fully closed position.

[0075] Based on vehicle gear status information, rainfall information, number of occupants in the vehicle information, and sunroof opening / closing information, a first state judgment is made. When the vehicle is in the first state, a second state judgment is made. When the vehicle is not in the first state, the next monitoring cycle begins.

[0076] The second state is when any door is open;

[0077] The system monitors the door opening status and makes a second-state judgment. When the vehicle is in the second state, it makes a third-state judgment. When the vehicle is not in the second state, the next monitoring cycle begins.

[0078] The third state is when the window opening position of the open door is not between the preset window opening position and the window fully open position;

[0079] The system monitors the opening position of the car window when the car door is open and makes a third state judgment. When the vehicle is in the third state, it monitors the state of the open door and controls the window of the open door to open to the preset window opening position before the open door closes. When it detects that the open door is in the closed state, it controls the window of the open door to return to the memory position corresponding to the open door.

[0080] When the vehicle is not in the third state, the open door window remains in its current position, the status of the open door is monitored, and when the open door is detected to be in the closed state, the next monitoring cycle begins.

[0081] Specifically, based on the vehicle model, pressure ear analysis is performed to determine the preset window opening position and the preset sunroof opening position.

[0082] In some specific embodiments, the structure of the vehicle anti-pinch ear system is as follows: Figure 1 As shown, the system composition and functions are as follows:

[0083] Rainfall sensor unit: refers to the unit that provides the vehicle with information on whether it is raining outside and the amount of rainfall. The vehicle uses this information to determine whether to open the window.

[0084] Door opening sensor unit: refers to the unit that provides information on the opening and closing status of the vehicle doors, and the vehicle determines whether to open the window based on this information.

[0085] Vehicle-mounted vision sensing unit: refers to the unit that provides information on the number of people inside the vehicle, and the vehicle determines whether to open the window based on this information.

[0086] Seat pressure sensor unit: This unit provides information on the number of occupants in the vehicle, and the vehicle uses this information to determine whether to open the window.

[0087] Window status sensor unit: refers to the unit that provides information on the open / closed status of the vehicle's windows, and uses this information to determine whether to open the window.

[0088] Sunroof status sensor unit: This unit provides the vehicle with information on the sunroof's open / closed status, and the vehicle uses this information to determine whether to open the sunroof.

[0089] Gear position sensor unit: refers to the unit that provides gear position information to the vehicle, and the vehicle uses this information to determine whether to open the window.

[0090] Control unit: It memorizes the positions of the four windows; based on rainfall information, door opening and closing information, number of occupants, window opening and closing information, and sunroof opening and closing information, it makes decisions on the opening and closing logic of the windows during the process of opening and closing inside the vehicle.

[0091] Window actuator: Executes the corresponding window opening and closing logic according to the requirements of the control unit.

[0092] Its control process is as follows Figure 2 As shown, specifically:

[0093] In S02, the positions of the four doors are memorized in the control unit.

[0094] In S03, the control unit determines whether the four doors are closed. If all four doors are found to be closed, the next step is determined; otherwise, the next monitoring cycle is started.

[0095] In S04, the control unit makes a judgment based on gear position information, weather (rain) information, number of people in the vehicle, and sunroof position: when the gear is P, the weather is not raining, there are more than 2 people in the vehicle, and the sunroof is open in a preset position (such as open 1 / 2) to fully closed position, the control unit proceeds to the next logic step; otherwise, it proceeds to the next monitoring cycle.

[0096] The determination of rainfall is as follows: when the rainfall reaches the set threshold, it is determined to be rain. The specific threshold is designed according to the designer's own calibration requirements. For example, light rain (rainfall intensity 0.0~5.0mm / 12h) is still calibrated as no rain.

[0097] Regarding the determination of the number of people inside the vehicle: ① Method 1: The onboard visual sensing unit (such as the DMS driver monitoring system and the OMS passenger monitoring system) determines the number of people inside the vehicle based on image recognition methods. ② Method 2: The presence of people is determined by whether the parameters given by the pressure sensors of each seat exceed a set threshold. For 5-seater or 7-seater SUVs, at least 4 sensors should be installed, specifically in the driver's seat, front passenger seat, left side of the second row, and right side of the rear row. To improve accuracy, pressure sensors can also be installed in the middle seat of the second row.

[0098] Regarding the preset position for sunroof opening, the designer needs to conduct an actual pressure ear analysis for their own vehicle model. For example, for a certain SUV, the designer believes that the pressure ear phenomenon is acceptable when the sunroof is opened 1 / 2.

[0099] It should be noted that when the vehicle does not have the ability to monitor the number of people (no visual sensing unit recognition capability, or no sufficient number of seat pressure sensors), S04 can make a judgment based solely on gear position information and weather (rain) information. That is, when the gear is in P and it is not raining, the next judgment is executed; otherwise, the next monitoring cycle is started.

[0100] In S05, the control unit monitors the door opening status. When it detects that a door A is open, it proceeds to the next step of judgment; otherwise, it proceeds to the next monitoring cycle.

[0101] In S06, the control unit determines the position of the A door window. ① When the opening position is between the preset position (e.g., open 1 / 4) and the fully open position: the A door window maintains its current position (corresponding to S06 to S07) and continuously monitors whether the A door is closed (corresponding to S08). When the A door is closed, the system's monitoring and judgment restarts (corresponding to S08 to S02). ② When the opening position is not between the preset position (e.g., open 1 / 4) and the fully open position: the control unit controls the A door window to open to the preset position (corresponding to S06 to S09) and proceeds to the next judgment.

[0102] Regarding the preset position for opening the car window, the designer needs to conduct an actual pressure ear analysis for their own vehicle model. For example, for a certain SUV, the designer considers the pressure ear phenomenon acceptable after the window is opened to 1 / 4.

[0103] In S10, the control unit monitors the closed state of door A. Before the door is detected to be closed, it controls the door window of door A to open to a preset position (corresponding to S10 to S11). When the door is detected to be closed, it controls the door window of door A to return to the memory position of door window A in S02 (corresponding to S11 to S12).

[0104] In this embodiment, a scene-based recognition and intelligent control of window opening is provided to eliminate the enclosed space inside the vehicle and solve the problem of ear pressure for passengers when there are still occupants inside the vehicle and the doors are closed, taking into account weather conditions.

[0105] This invention also provides a method for preventing vehicle pressure ears, comprising the following steps:

[0106] The number of occupants inside the vehicle is determined using an occupant quantity sensing unit;

[0107] Obtain the opening positions of all doors and windows from the door opening and closing status information, and get the memory positions of all doors and windows;

[0108] When all car doors are detected to be closed, the first state judgment is performed; when not all car doors are detected to be closed, the next monitoring cycle begins.

[0109] The first state is that the gear is in P gear, it is not raining, the number of occupants in the vehicle is not less than 2, and the sunroof opening position is between the preset sunroof opening position and the sunroof fully closed position.

[0110] Based on vehicle gear status information, rainfall information, number of occupants in the vehicle information, and sunroof opening / closing information, a first state judgment is made. When the vehicle is in the first state, a second state judgment is made. When the vehicle is not in the first state, the next monitoring cycle begins.

[0111] The second state is when any door is open;

[0112] The system monitors the door opening status and makes a second-state judgment. When the vehicle is in the second state, it makes a third-state judgment. When the vehicle is not in the second state, the next monitoring cycle begins.

[0113] The third state is when the window opening position of the open door is not between the preset window opening position and the window fully open position;

[0114] The system monitors the opening position of the car window when the car door is open and makes a third state judgment. When the vehicle is in the third state, it monitors the state of the open door and controls the window of the open door to open to the preset window opening position before the open door closes. When it detects that the open door is in the closed state, it controls the window of the open door to return to the memory position corresponding to the open door.

[0115] When the vehicle is not in the third state, the open door window remains in its current position, the status of the open door is monitored, and when the open door is detected to be in the closed state, the next monitoring cycle begins.

[0116] Specifically, the number of occupants in the vehicle is determined using an occupant quantity sensing unit, including the following steps:

[0117] When the occupant quantity sensing unit includes both an in-vehicle vision sensor and a seat pressure sensor, the occupant quantity sensing unit compares the occupant quantity information acquired by the in-vehicle vision sensor and the seat pressure sensor. This occupant quantity information includes the number of occupants and their corresponding accuracy. If the number of occupants acquired by the in-vehicle vision sensor and the seat pressure sensor is the same, the occupant quantity sensing unit sends the consistent occupant quantity. If the number of occupants acquired by the in-vehicle vision sensor and the seat pressure sensor is different, the occupant quantity sensing unit sends the occupant quantity with higher accuracy. When the occupant quantity sensing unit includes only an in-vehicle vision sensor or a seat pressure sensor, the occupant quantity sensing unit sends the occupant quantity provided by the corresponding sensor.

[0118] Specifically, the vehicle anti-pinch ear method further includes the following steps:

[0119] Based on the vehicle model, pressure ear analysis was performed to determine the preset window opening position and the preset sunroof opening position;

[0120] Based on the obtained rainfall information and the preset rainfall threshold, it is determined whether it is raining.

[0121] In this embodiment, a scene-based recognition and intelligent control of window opening is provided to eliminate the enclosed space inside the vehicle and solve the problem of ear pressure for passengers when there are still occupants inside the vehicle and the doors are closed, taking into account weather conditions.

[0122] Based on the same inventive concept, embodiments of the present invention also provide a vehicle, including the vehicle anti-pinch system as described above, or a window opening strategy designed using the vehicle anti-pinch method as described above.

[0123] Those skilled in the art can change the above order without departing from the scope of protection of this disclosure.
