[0037] With the mass production and popularity of intelligent functions on vehicles, the driving and riding experience of drivers and passengers has been significantly improved compared to traditional vehicles, but generally embodied in the improvement of comfort and entertainment, and few special designs are made for driving safety systems. Safety is the most important point in the driving process, which needs to be considered in the overall design of the vehicle. In the current safety design, comfort and safety are mainly reflected for the whole vehicle or the front row, and there is a lack of comfort and safety consideration for the rear row.

[0038] In order to solve the above problems and improve the comfort and safety of the rear passengers, the application provides a driving mode determination method, device, equipment and storage medium. The driving mode determination device obtains the sitting posture adjustment frequency of the passengers on the vehicle; and determines the activity intensity of the passengers according to the sitting posture adjustment frequency. The activity intensity includes low-frequency activity intensity, medium-frequency activity intensity and high-frequency activity intensity. Further, the driving mode determination device determines that the activity intensity of the passengers is high-frequency activity intensity when the sitting posture adjustment frequency is greater than a first preset frequency; and determines that the vehicle runs in a first driving mode when the activity intensity of the passengers is high-frequency activity intensity. The driving parameters corresponding to the first driving mode are smaller than the driving parameters corresponding to the normal driving mode. The driving parameters include maximum steering rate, maximum braking acceleration and maximum driving acceleration.

[0039] In this way, in the driving mode determination method provided by the application, by determining the sitting posture adjustment frequency of the rear passengers, the activity intensity of the passengers is determined. When the activity intensity of the passengers is high-frequency activity intensity, in order to avoid the safety risk or discomfort of the passengers caused by the too fast steering, acceleration and deceleration of the driver, the vehicle is determined to run in the first driving mode, so as to travel at a lower maximum steering rate, a lower maximum braking acceleration and a lower maximum driving speed. The driving parameters optimize the driving strategy of the vehicle, and improve the comfort and safety of the rear passengers during the driving of the vehicle.

[0040] Figure 1 A driving mode determination system is shown. The driving mode determination method provided by the embodiments of the application can be applied to, for example Figure 1The driving mode determination system shown is used to improve the comfort and safety of the rear passengers during the driving of the vehicle. As shown in Figure 1 The driving mode determination system 10 includes a driving mode determination device 11, a pressure sensor 12, a biological sensor 13, and a camera device 14.

[0041] The driving mode determination device 11 is connected to the pressure sensor 12, the biological sensor 13, and the camera device 14 respectively. The connection can be wired or wireless, which is not limited in the embodiments of the present application.

[0042] It should be noted that the driving mode determination system 10, the driving mode determination device 11, the pressure sensor 12, the biological sensor 13, and the camera device 14 included in the driving mode determination system 10 are all deployed in the same vehicle.

[0043] The pressure sensor 12 is deployed on the rear seat of the vehicle and can be used to detect the pressure on the rear seat.

[0044] The biological sensor 13 is deployed on the rear seat of the vehicle and can be used to detect the heartbeat of the occupant sitting on the rear seat.

[0045] The camera device 14 includes a camera device A 141 and a camera device B 142. The camera device A 141 is deployed behind the headrest of the driver's seat, and the camera device B 142 is deployed behind the headrest of the front passenger's seat. Alternatively, the camera device A 141 is deployed behind the headrest of the front passenger's seat, and the camera device B 142 is deployed behind the headrest of the driver's seat, which is not limited in the embodiments of the present application.

[0046] The camera device 14 can be used to detect the sitting posture of the occupant sitting on the rear seat, which includes sitting and lying.

[0047] The camera device 14 can also be used to detect the blink frequency and eyelid closure degree of the occupant sitting on the rear seat.

[0048] The driving mode determination device 11 can be used to obtain the pressure of the occupant sitting on the rear seat from the pressure sensor 12, and determine that the occupant has adjusted the sitting posture if the difference between the pressure value at the previous time and the pressure value at the current time is greater than the preset pressure difference value. Further, the driving mode determination device 11 can also be used to determine the sitting posture adjustment frequency of the occupant within a preset time length.

[0049] The driving mode determination device 11 can also be used to obtain the heartbeat of the occupant sitting on the rear seat from the biological sensor 13.

[0050] The driving mode determination apparatus 11 can also be configured to acquire the sitting posture state of the occupant seated on the rear seat from the camera 14. Furthermore, the driving mode determination apparatus 11 can also be configured to acquire the blink frequency of the occupant seated on the rear seat within a preset period and the eyelid closure degree of the occupant from the camera 14.

[0051] The driving mode determination apparatus 11 can also be configured to determine the activity intensity of the occupant according to the sitting posture adjustment frequency of the occupant.

[0052] The activity intensity includes low-frequency activity intensity, medium-frequency activity intensity, and high-frequency activity intensity.

[0053] The driving mode determination apparatus 11 can also be configured to determine that the vehicle is operated in the first driving mode when the activity intensity of the occupant is the high-frequency activity intensity.

[0054] The first driving mode corresponds to driving parameters smaller than those of the normal driving mode, and the driving parameters include maximum steering rate, maximum braking acceleration, and maximum driving acceleration.

[0055] Figure 2 FIG. 1 is a schematic diagram of a driving mode determination method according to some example embodiments. In some embodiments, the driving mode determination method described above can be applied to the driving mode determination apparatus 11 in the driving mode determination system 10 as shown in FIG. 1. Hereinafter, the embodiments of the present application take the driving mode determination method applied to the driving mode determination apparatus 11 as an example to describe the driving mode determination method described above. Figure 1

[0056] As shown in FIG. 1, the driving mode determination method provided by the embodiments of the present application includes the following S201-S206. Figure 2

[0057] S201, the driving mode determination apparatus acquires the sitting posture adjustment frequency of the occupant in the vehicle.

[0058] As a possible implementation manner, the driving mode determination apparatus acquires the seat pressure change reported by the pressure sensor in real time. Further, the driving mode determination apparatus determines the pressure difference between the seat pressures reported by the pressure sensor at adjacent time points, and determines that the occupant in the vehicle has adjusted the sitting posture when the pressure difference is greater than a preset pressure difference. Further, the driving mode determination apparatus counts the number of times of the sitting posture adjustment of the occupant within a preset time length, and determines the sitting posture adjustment frequency of the occupant.

[0059] It should be noted that the preset pressure difference and the preset time length can be set in the driving mode determination apparatus by the operation and maintenance personnel of the driving mode determination system in advance, and the embodiments of the present application do not make specific limitations thereto.

[0060] ​​For example, if the preset time length is 5 minutes, and the number of times of adjusting the sitting posture in the preset time length counted by the driving mode determination apparatus is 7, 5, 6, 4, and 8 respectively, the frequency of adjusting the sitting posture of the occupant is determined to be (7+5+6+4+8) / 5=6 times / minute.

[0061] As another possible implementation, the driving mode determination apparatus acquires the frequency of adjusting the sitting posture reported by the pressure sensor periodically.

[0062] In this case, the pressure sensor calculates the number of times of adjusting the sitting posture in a statistical period after the statistical period ends, and reports the calculated number of times of adjusting the sitting posture to the driving mode determination apparatus.

[0063] S202, the driving mode determination apparatus determines the activity intensity of the occupant according to the frequency of adjusting the sitting posture.

[0064] In this case, the activity intensity includes low-frequency activity intensity, medium-frequency activity intensity, and high-frequency activity intensity.

[0065] In some embodiments, the driving mode determination apparatus determines the activity intensity of the occupant according to the frequency of adjusting the sitting posture, including steps S2021, S2022, and S2023.

[0066] In S2021, when the frequency of adjusting the sitting posture is greater than a first preset frequency, the driving mode determination apparatus determines that the activity intensity of the occupant is high-frequency activity intensity.

[0067] In S2022, when the frequency of adjusting the sitting posture is greater than a second preset frequency and less than the first preset frequency, and the sitting posture state of the occupant is upright sitting, the driving mode determination apparatus determines that the activity intensity of the occupant is medium-frequency activity intensity.

[0068] It should be noted that, when the frequency of adjusting the sitting posture is greater than the second preset frequency and less than the first preset frequency, the driving mode determination apparatus acquires the sitting posture state of the occupant from the camera, determines whether the sitting posture state of the occupant is upright sitting, and when the sitting posture state of the occupant is upright sitting, determines that the activity intensity of the occupant is medium-frequency activity intensity.

[0069] In S2023, when the frequency of adjusting the sitting posture is less than a third preset frequency, the driving mode determination apparatus determines that the activity intensity of the occupant is low-frequency activity intensity.

[0070] It should be noted that the first preset frequency, the second preset frequency and the third preset frequency can be set in the driving mode determination device in advance by an operator of the driving mode determination system, wherein the first preset frequency is greater than the second preset frequency, and the second preset frequency is greater than or equal to the third preset frequency. For example, the first preset frequency can be 10 times per minute, the second preset frequency can be 5 times per minute, and the third preset frequency can be 5 times per minute, which are not limited in the embodiments of the present application.

[0071] For example, in the case that the first preset frequency is 10 times per minute, the second preset frequency is 5 times per minute, and the third preset frequency is 5 times per minute, if the frequency of the passenger's sitting posture adjustment is 12 times per minute, it is determined that the activity intensity of the passenger is a high-frequency activity intensity; if the frequency of the passenger's sitting posture adjustment is 3 times per minute, it is determined that the activity intensity of the passenger is a low-frequency activity intensity; if the frequency of the passenger's sitting posture adjustment is 6 times per minute, the sitting posture state of the passenger is further obtained from the camera device, and in the case that the sitting posture state of the passenger is sitting, it is determined that the activity intensity of the passenger is a medium-frequency activity intensity.

[0072] S203, in the case that the activity intensity of the passenger is a high-frequency activity intensity, the driving mode determination device determines that the vehicle is operated in a first driving mode.

[0073] The driving parameters corresponding to the first driving mode are less than the driving parameters corresponding to the normal driving mode, and the driving parameters include a maximum steering rate, a maximum braking acceleration and a maximum driving acceleration.

[0074] It should be noted that in some embodiments, the driving parameters corresponding to the first driving mode are a first maximum steering rate, a first maximum braking acceleration and a first maximum driving acceleration. The first maximum steering rate is 80% of the maximum steering rate corresponding to the normal driving mode, the first maximum braking acceleration is 90% of the braking acceleration corresponding to the normal driving mode, and the first maximum driving acceleration is 80% of the maximum driving acceleration corresponding to the normal driving mode.

[0075] S204, in the case that the activity intensity of the passenger is a medium-frequency activity intensity, the driving mode determination device determines that the vehicle is operated in a second driving mode.

[0076] The driving parameters corresponding to the second driving mode are less than the driving parameters corresponding to the normal driving mode, and the driving parameters corresponding to the second driving mode are greater than or equal to the driving parameters corresponding to the first driving mode.

[0077] It should be noted that, in some embodiments, the driving parameter corresponding to the second driving mode is a second maximum steering rate, a second maximum braking acceleration, and a second maximum driving acceleration, the second maximum steering rate is 90% of the maximum steering rate corresponding to the normal driving mode, the second maximum braking acceleration is 90% of the braking acceleration corresponding to the normal driving mode, and the second maximum driving acceleration is 90% of the maximum driving acceleration corresponding to the normal driving mode.

[0078] S205, in the case where the activity intensity of the occupant is a low-frequency activity intensity, the driving mode determination device determines whether the occupant is in a sleep state.

[0079] As a possible implementation, in the case where the activity intensity of the occupant is a low-frequency activity intensity, the driving mode determination device acquires the blink frequency, the eyelid closure degree, and the heart rate fluctuation frequency of the occupant. Further, the driving mode determination device determines that the occupant is in a sleep state in the case where the blink frequency is less than a preset blink frequency, the eyelid closure degree is less than a preset eyelid closure degree, and the heart rate fluctuation frequency is greater than a preset heart rate fluctuation frequency.

[0080] It should be noted that the preset blink frequency, the preset eyelid closure degree, and the preset heart rate fluctuation frequency can be preset in the driving mode determination device by the operation and maintenance personnel of the driving mode determination system, for example, the preset blink frequency is 5 times per minute, the preset eyelid closure degree is 10%, and the preset heart rate fluctuation frequency is 10 times per minute, which is not limited in the embodiments of the present application.

[0081] For example, the preset blink frequency is 5 times per minute, the preset eyelid closure degree is 10%, and the preset heart rate fluctuation frequency is 10 times per minute, in the case where the activity intensity of the occupant is a low-frequency activity, if the blink frequency of the occupant is 3 times per minute, the eyelid closure degree is 0, and the preset heart rate fluctuation frequency is 12 times per minute, it is determined that the occupant is in a sleep state; if the blink frequency of the occupant is 6 times per minute, the eyelid closure degree is 5%, and the preset heart rate fluctuation frequency is 11 times per minute, it is determined that the occupant is not in a sleep state; if the blink frequency of the occupant is 6 times per minute, the eyelid closure degree is 50%, and the preset heart rate fluctuation frequency is 4 times per minute, it is determined that the occupant is not in a sleep state.

[0082] In some embodiments, in order to more accurately determine whether the occupant is in a sleep state, the driving mode determination device determines that the occupant is in a sleep state in the case where the heart rate fluctuation frequency of the occupant is greater than the preset heart rate fluctuation frequency for a continuous period of time, for example, the continuous period of time can be 5 minutes.

[0083] S206, in the case where the occupant is in a sleep state, it is determined that the vehicle is operated in the first driving mode.

[0084] In some embodiments, in the case that the activity intensity of the occupant is a low-frequency activity intensity, the driving mode determination apparatus determines that the occupant is in a normal state in the case that the blink frequency is greater than or equal to a preset blink frequency, the eyelid closure degree is greater than or equal to a preset eyelid closure degree, or the heart rate fluctuation frequency is less than or equal to a preset heart rate fluctuation frequency. Further, the driving mode determination apparatus determines that the vehicle operates in a normal driving mode.

[0085] It can be understood that, in the driving mode determination method provided by the embodiments of the present application, in the case that the occupant is in a high activity intensity or a sleep state, the vehicle is controlled to operate at a lower steering, acceleration, and braking, so as to avoid the rapid change of the driving state of the vehicle, and to avoid the influence on the comfort and safety of the occupant, and to ensure the riding experience of the occupant.

[0086] In one design, the driving mode determination system shown in Figure 1 The driving mode determination system shown in Figure 3 The driving mode determination apparatus includes an activity state processing unit 111 and a personnel state processing unit 112, wherein the activity state processing unit 111 is connected with the pressure sensor 12, the camera A 141, and the camera B 142 respectively, and the personnel state processing unit 112 is connected with the biological sensor 13, the camera A 141, and the camera B 142 respectively.

[0087] The driving mode determination method shown in Figure 3 The activity state processing unit 111 is configured to determine whether the activity intensity of the occupant is a low-frequency activity intensity, a medium-frequency activity intensity, or a high-frequency activity intensity according to the data transmitted by the pressure sensor 12, the camera A 141, and the camera B 142, and determine that the vehicle operates in a second driving mode in the case that the activity intensity is a medium-frequency activity intensity, and determine that the vehicle operates in a first driving mode in the case that the activity intensity is a high-frequency activity intensity.

[0088] In addition, in the case that the activity intensity is a low-frequency activity intensity, the personnel state processing unit 112 determines whether the occupant is in a sleep state according to the data transmitted by the biological sensor 13, the camera A 141, and the camera B 142, and determines that the vehicle operates in the first driving mode in the case that the occupant is in a sleep state, and determines that the vehicle operates in a normal driving mode in the case that the occupant is in a non-sleep state.

[0089] In one design, the driving mode determination system shown in Figure 3 The driving mode determination system shown in Figure 4 A driving mode determination system 30 is shown, the activity state processing unit 111 and the personnel state processing unit 112 are connected with a driving control unit 151 respectively, and the driving control unit 151 is further connected with a driving system 152, a braking system 153, and a steering system 154 respectively.

[0090] The activity state processing unit 111 is configured to send the driving parameters corresponding to the first driving mode and the driving parameters corresponding to the second driving mode to the driving control unit 151, so that the driving control unit 151 sends the driving driving parameters corresponding to the first driving mode or the second driving mode to the driving system 152, sends the corresponding braking driving parameters to the braking system 153, and sends the corresponding steering driving parameters to the steering system 154.

[0091] The personnel state processing unit 112 is configured to send the driving parameters corresponding to the first driving mode and the driving parameters corresponding to the normal driving mode to the driving control unit 151, so that the driving control unit 151 sends the driving driving parameters corresponding to the first driving mode or the normal driving mode to the driving system 152, sends the corresponding braking driving parameters to the braking system 153, and sends the corresponding steering driving parameters to the steering system 154.
