Description

[Technical field]

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a seat leaving detection method, device, vehicle controller and vehicle. [Background technology]

[0002] At present, when a new energy vehicle is in a drivable state (i.e., READY state), it is usually required to remind the driver when it is detected that the driver is out of the seat, so as to ensure driving safety.

[0003] In the related art, relevant sensors, such as seat occupancy sensors, are often set on the seat to detect whether the driver is in a vacant seat state. However, the above method may be affected by factors such as the driver's sitting position and the driver's weight, resulting in the seat occupancy sensor being unable to accurately detect whether the driver is in a vacant seat state. At the same time, the additional setting of seat occupancy sensors will also increase the cost of the entire vehicle to a certain extent. [Summary of the invention]

[0004] The embodiments of the present application propose a seat leaving detection method, device, vehicle controller and vehicle, which can accurately detect whether the driver is in a seat leaving state without relying on additional auxiliary equipment, while also reducing the cost of the vehicle.

[0005] In a first aspect, an embodiment of the present application provides a seat leaving detection method, the method comprising:

[0006] When it is determined that the vehicle is in a drivable state, obtaining operating state parameters related to the driving behavior of the driver in the vehicle;

[0007] It is determined whether the driver is in a seat-out state based on the operating state parameter.

[0008] In the embodiment of the present application, when it is determined that the vehicle is in a drivable state, the operating state parameters related to the driver's driving behavior in the vehicle can be obtained. Since the operating state parameters can reflect the driver's driving behavior to a certain extent, it is possible to more accurately determine whether the driver is in a seat-out state based on the operating state parameters. At the same time, since there is no need to set up additional auxiliary equipment, such as a seat occupancy sensor, during the above detection process, the cost of the entire vehicle is reduced.

[0009] Optionally, the operating status parameter includes one or more combinations of vehicle speed, door status, seat belt status, and lane departure status.

[0010] In the embodiment of the present application, a combination of one or more of the vehicle speed, door status, seat belt status, and lane departure status may be obtained to accurately determine whether the driver is in a state of leaving the seat.

[0011] Optionally, determining whether the driver is in a seat-out state based on the operating state parameter includes:

[0012] If it is determined that the door state is switched from a closed state to an open state, and the seat belt state is switched from an activated state to a non-activated state, it is determined that the driver is in a seat-out state.

[0013] In an embodiment of the present application, whether the driver is out of the seat can be determined based on a combination of the door status and the seat belt status. For example, when the door status is switched from a closed state to an open state, and the seat belt status is switched from an enabled state to a disabled state, it can be considered that the driver is out of the seat.

[0014] Optionally, if it is determined that the door state is switched from a closed state to an open state, and the seat belt state is switched from an enabled state to a disabled state, then determining that the driver is in a seat-out state includes:

[0015] If it is determined that the vehicle speed is not greater than a set threshold, the door state is switched from a closed state to an open state, and the seat belt state is switched from an enabled state to a disabled state, it is determined that the driver is in a seat-out state when the vehicle is stationary.

[0016] In the embodiment of the present application, it is possible to determine whether the driver is in a state of leaving the seat when the vehicle is stationary (i.e., in a drivable state but not yet started to drive) based on a combination of vehicle speed, door state, and seat belt state. For example, when the vehicle speed is not greater than a set threshold, it can be considered that the current vehicle is stationary. At this time, if the door state is switched from a closed state to an open state, and the seat belt state is switched from an enabled state to a disabled state, it can be considered that the driver is in a state of leaving the seat when the vehicle is stationary.

[0017] Optionally, if it is determined that the door state is switched from a closed state to an open state, and the seat belt state is switched from an enabled state to a disabled state, then determining that the driver is in a seat-out state includes:

[0018] If it is determined that the vehicle speed is greater than a set threshold, the door state is switched from a closed state to an open state, and the seat belt state is switched from an enabled state to a disabled state, it is determined that the driver is out of the seat during the driving of the vehicle.

[0019] In the embodiment of the present application, it is possible to determine whether the driver is in a state of leaving the seat during the driving process of the vehicle based on the combination of the vehicle speed, the door state and the seat belt state. For example, when the vehicle speed is greater than a set threshold, it can be considered that the current vehicle is in the driving process. At this time, if the door state is switched from a closed state to an open state, and the seat belt state is switched from an enabled state to a disabled state, it can be considered that the driver is in a state of leaving the seat during the driving process of the vehicle.

[0020] Optionally, if it is determined that the vehicle speed is greater than a set threshold, the door state is switched from a closed state to an open state, and the seat belt state is switched from an enabled state to a disabled state, then it is determined that the driver is in a seat-free state during the driving of the vehicle, including:

[0021] If it is determined that the vehicle speed is greater than the set threshold, the door state is switched from a closed state to an open state, the seat belt state is switched from an enabled state to a disabled state, and the lane deviation state exceeds a set degree, it is determined that the driver is in a seat-free state during the driving of the vehicle.

[0022] In the embodiment of the present application, it is possible to determine whether the driver is in a state of leaving the seat during the driving process of the vehicle based on a combination of vehicle speed, door status, seat belt status, and lane deviation status. For example, when the vehicle speed is greater than a set threshold, it can be considered that the current vehicle is in the driving process. At this time, if the door status is switched from a closed state to an open state, the seat belt status is switched from an enabled state to a disabled state, and the lane deviation status exceeds a set degree, it can be considered that the driver is in a state of leaving the seat during the driving process of the vehicle.

[0023] Optionally, determining whether the driver is in a seat-out state based on the operating state parameter includes:

[0024] If it is determined that the vehicle speed is greater than a set threshold, the lane departure state exceeds a set degree, and the seat belt state is switched from an enabled state to a disabled state, it is determined that the driver is out of the seat during driving of the vehicle.

[0025] In the embodiment of the present application, it is possible to determine whether the driver is in a state of leaving the seat during the driving process of the vehicle based on the combination of vehicle speed, seat belt status, and lane deviation status. For example, when the vehicle speed is greater than a set threshold, it can be considered that the current vehicle is in the driving process. At this time, if the seat belt status is switched from an enabled state to a disabled state, and the lane deviation status exceeds a set degree, it can be considered that the driver is in a state of leaving the seat during the driving process of the vehicle.

[0026] Optionally, the method further includes:

[0027] If it is determined that the driver is in a state of leaving the seat, the vehicle is controlled to output a reminder message, where the reminder message is used to remind the driver to return to the seat.

[0028] In an embodiment of the present application, whether the vehicle is stationary or driving, as long as it is detected that the driver is out of the seat, a reminder message can be output to remind the driver to return to the seat, thereby ensuring the driver's driving safety.

[0029] In a second aspect, an embodiment of the present application provides a seat leaving detection device, the device comprising:

[0030] an acquisition unit, configured to acquire, when determining that the vehicle is in a drivable state, an operating state parameter related to the driving behavior of the driver in the vehicle;

[0032] Optionally, the operating status parameter includes one or more combinations of vehicle speed, door status, seat belt status, and lane departure status.

[0033] Optionally, the determining unit includes:

[0034] The first seat leaving state determining subunit is used to determine that the driver is in the seat leaving state if it is determined that the door state is switched from the closed state to the open state, and the seat belt state is switched from the activated state to the unactivated state.

[0041] Optionally, the determining unit further includes:

[0042] The second out-of-seat state determination subunit is used to determine that the driver is in an out-of-seat state during the driving of the vehicle if it is determined that the vehicle speed is greater than a set threshold, the lane deviation state exceeds a set degree, and the seat belt state is switched from an enabled state to a disabled state.

[0043] Optionally, the device further comprises:

[0044] The control unit is used to control the vehicle to output a reminder message if it is determined that the driver is out of the seat, wherein the reminder message is used to remind the driver to return to the seat.

[0059] In order to better understand the technical solution of this specification, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0060] It should be clear that the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0061] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit this specification. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0062] At present, when a new energy vehicle is in a drivable state (i.e., READY state), it is usually required to remind the driver when it is detected that the driver is out of the seat, so as to ensure driving safety.

[0063] In the related art, relevant sensors, such as seat occupancy sensors, are often set on the seat to detect whether the driver is in a vacant seat state. However, the above method may be affected by factors such as the driver's sitting position and the driver's weight, resulting in the seat occupancy sensor being unable to accurately detect whether the driver is in a vacant seat state. At the same time, the additional setting of seat occupancy sensors will also increase the cost of the entire vehicle to a certain extent.

[0064] In view of this, an embodiment of the present application provides a seat leaving detection method, in which an operating state parameter related to the driver's driving behavior is obtained from the vehicle. Since the operating state parameter can reflect the driver's driving behavior to a certain extent, it is possible to more accurately determine whether the driver is in a seat leaving state based on the operating state parameter. At the same time, since there is no need to set up additional auxiliary equipment, such as a seat occupancy sensor, during the above detection process, the cost of the entire vehicle is reduced.

[0065] The technical solution provided by the embodiments of the present application is introduced below in conjunction with the accompanying drawings.

[0066] See also Figure 1 , is a flow chart of a seat leaving detection method provided in an embodiment of the present application. The method can be applied to a vehicle control unit (VCU). The flow chart of the method is as follows:

[0067] Step 10: When it is determined that the vehicle is in a drivable state, the operating state parameters of the vehicle related to the driving behavior of the driver are obtained.

[0068] In the embodiment of the present application, when the vehicle is in a drivable state (i.e., READY), whether the driver is in a seat-out state can be considered to be related to the driver's driving behavior. Therefore, if it is necessary to detect whether the driver is in a seat-out state, the operating state parameters related to the driver's driving behavior in the vehicle can be obtained.

[0069] For example, the above-mentioned operating status parameters include one or more combinations of the vehicle speed calculated by the Electronic Stability Control (ESC) module based on the wheel speed sensor data, the door status collected by the Integrated Body Control (IBC), the seat belt status collected by the airbag module (Sensor Digital Module, SDM), and the lane departure status collected by the Lane Departure Warning (LDW) system or the Lane Keeping Assist (Lane Keeping Assist, LKA) system.

[0070] Step 20: Determine whether the driver is in a seat-leaving state based on the operating state parameter.

[0071] In the embodiment of the present application, since the above operating state parameters can reflect the driving behavior of the driver to a certain extent, it is possible to more accurately determine whether the driver is in a seat-out state based on the operating state parameters. At the same time, since there is no need to set up additional auxiliary equipment, such as a seat occupancy sensor, during the above detection process, the cost of the entire vehicle is reduced.

[0072] How to determine whether the driver is in the seat-leaving state based on the vehicle's operating state parameters is described in detail below.

[0073] In the embodiment of the present application, whether the driver is in the out-of-seat state can be determined based on the combination of the door state and the seat belt state in the operating state parameters.

[0074] See also Figure 2 , which is a flow chart of a method for determining a seat vacancy status provided in an embodiment of the present application. Step 20 can be implemented by executing sub-step 201:

[0075] Step 201: If it is determined that the door state is switched from the closed state to the open state, and the seat belt state is switched from the enabled state to the disabled state, it is determined that the driver is in the seat-out state.

[0076] In the embodiment of the present application, considering that when the vehicle is in a drivable state, the driver's normal driving behavior should be to close the door, fasten the seat belt, and be ready to drive the vehicle at any time or have already started driving the vehicle. Therefore, if the vehicle controller determines that the door state is switched from the closed state to the open state (i.e., the door is not closed), and the seat belt state is switched from the enabled state to the unenabled state (i.e., the seat belt is not fastened), it can be considered that the driver is not in the driving seat, that is, in the out-of-seat state. Conversely, if any of the above conditions is not met, it can be considered that the driver is not in the out-of-seat state.

[0077] It is worth noting that the above embodiment is applicable to the judgment of whether the driver is in a drivable state and has not started driving, and is also applicable to the judgment of whether the driver is in a drivable state and has started driving.

[0078] In some embodiments, considering that the driver is in the seat-out state before starting to drive and during driving, the vehicle may need to output different reminders to improve the driver's experience. Therefore, in the embodiment of the present application, it is possible to judge whether the driver is in the seat-out state before starting to drive and during driving.

[0079] Scenario 1: Determine whether the driver is away from the vehicle before starting to drive.

[0080] See also Figure 3 , is a flow chart of a method for determining a seat-leaving state before starting driving provided in an embodiment of the present application. Step 201 can be specifically implemented by executing sub-step 211:

[0081] Step 2011: If it is determined that the vehicle speed is not greater than the set threshold, the door state is switched from the closed state to the open state, and the seat belt state is switched from the enabled state to the disabled state, it is determined that the driver is in the out-of-seat state when the vehicle is stationary.

[0082] In the embodiment of the present application, whether the driver is out of the seat when the vehicle is stationary (i.e., in a drivable state but has not started driving) can be determined based on a combination of vehicle speed, door status, and seat belt status.

[0083] As a possible implementation, when the vehicle speed is not greater than a set threshold, the current vehicle can be considered to be stationary. At this time, if the door state is switched from closed to open, and the seat belt state is switched from enabled to disabled, it can be considered that the driver is in a state of leaving the seat when the vehicle is stationary. Conversely, if any of the above conditions (door state, seat belt state) is not met, it can be considered that the driver is not in a state of leaving the seat when the vehicle is stationary.

[0084] For example, the above-mentioned set threshold may be 2km / h, 3km / h, or 4km / h, and this application does not impose any particular limitation on this.

[0085] Scenario 2: Determine whether the driver is away from his seat during driving.

[0086] See also Figure 4 , is a flow chart of a method for determining a seat leaving state during vehicle driving provided by an embodiment of the present application. Step 201 can be implemented by executing sub-step 2012:

[0087] Step 2012: If it is determined that the vehicle speed is greater than a set threshold, the door state is switched from a closed state to an open state, and the seat belt state is switched from an enabled state to a disabled state, it is determined that the driver is out of the seat during vehicle driving.

[0088] In the embodiment of the present application, whether the driver is out of the seat while the vehicle is moving can be determined based on a combination of the vehicle speed, the door status, and the seat belt status.

[0089] As a possible implementation, when the vehicle speed is greater than a set threshold, it can be considered that the current vehicle is in the process of driving. At this time, if the door state is switched from the closed state to the open state, and the seat belt state is switched from the enabled state to the disabled state, it can be considered that the driver is in the state of leaving the seat during the driving of the vehicle. On the contrary, if any of the above conditions (door state, seat belt state) is not met, it can be considered that the driver is not in the state of leaving the seat during the driving of the vehicle. It should be understood that in this embodiment, it can be considered that the driver has not turned on the automatic locking function of the vehicle, which means that when the vehicle speed exceeds the set threshold, the door can be opened.

[0090] For example, the above-mentioned set threshold may be 2km / h, 3km / h, or 4km / h, and this application does not impose any particular limitation on this.

[0091] In some embodiments, considering that when the driver is out of the seat during driving, the driver's line of sight may not be focused on the front of the vehicle, which may cause the vehicle to deviate from the lane during driving. In other words, the lane deviation of the vehicle may be related to the driver being out of the seat. Therefore, in the embodiments of the present application, the lane deviation state of the current vehicle can also be used to assist in determining whether the driver is out of the seat during driving.

[0092] See also Figure 5 , is a flow chart of a method for determining a seat leaving state during vehicle driving provided by an embodiment of the present application. Step 2012 can be specifically implemented by executing sub-step 20121:

[0093] Step 20121: If it is determined that the vehicle speed is greater than a set threshold, the door state is switched from a closed state to an open state, the seat belt state is switched from an enabled state to a disabled state, and the lane deviation state exceeds a set degree, it is determined that the driver is out of the seat during vehicle driving.

[0094] In the embodiment of the present application, whether the driver is out of the seat during driving of the vehicle can be determined based on a combination of vehicle speed, door status, seat belt status, and lane departure status.

[0095] As a possible implementation, when the vehicle speed is greater than a set threshold, it can be considered that the current vehicle is in the process of driving. At this time, if the door state is switched from the closed state to the open state, the seat belt state is switched from the enabled state to the disabled state, and the lane deviation state exceeds the set degree (i.e., the lane deviation is relatively serious and can be considered to be caused by the driver's abnormal driving behavior), it can be considered that the driver is in the state of leaving the seat during the driving of the vehicle. Conversely, if any of the above conditions (door state, seat belt state, lane deviation state) is not met, it can be considered that the driver is not in the state of leaving the seat during the driving of the vehicle.

[0096] For example, the above-mentioned set threshold may be 2km / h, 3km / h, or 4km / h, and this application does not impose any particular limitation on this.

[0097] In some embodiments, it is considered that the driver may leave the seat during driving, but the door may not be in the open state. For example, the driver leaves the seat to pick up a dropped item in the car, and there is no need to open the door at this time. At the same time, the vehicle has an automatic locking function, that is, when the vehicle speed exceeds a set threshold, the door will automatically lock. Therefore, in the embodiment of the present application, when judging whether the driver is in the state of leaving the seat during driving, it is also possible not to consider the state of the door.

[0098] See also Figure 6 , is a flow chart of a method for determining a seat leaving state during vehicle driving provided by an embodiment of the present application. Step 20 can be implemented by executing sub-step 202:

[0099] Step 202: If it is determined that the vehicle speed is greater than a set threshold, the lane departure state exceeds a set degree, and the seat belt state is switched from an enabled state to a disabled state, it is determined that the driver is out of the seat during vehicle driving.

[0100] In the embodiment of the present application, whether the driver is out of the seat while the vehicle is moving can be determined based on a combination of the vehicle speed, the seat belt status, and the lane departure status.

[0101] As a possible implementation, when the vehicle speed is greater than a set threshold, it can be considered that the current vehicle is in the process of driving. At this time, if the seat belt status is switched from the enabled state to the disabled state, and the lane deviation state exceeds the set degree (i.e., the lane deviation is relatively serious, which can be considered to be caused by the driver's abnormal driving behavior), it can be considered that the driver is in the state of leaving the seat during the driving of the vehicle. Conversely, if any of the above conditions (seat belt status, lane deviation status) is not met, it can be considered that the driver is not in the state of leaving the seat during the driving of the vehicle.

[0102] For example, the above-mentioned set threshold may be 2km / h, 3km / h, or 4km / h, and this application does not impose any particular limitation on this.

[0103] Further, whether the vehicle is in a drivable state, has not started driving (i.e., stationary state), or is already in the driving process, as long as it is detected that the driver is in a state of leaving the seat, a reminder message can be output, and the reminder message is used to remind the driver to return to the seat, thereby ensuring the driver's driving safety. The specific reminder content is not particularly limited in this application. The presentation method of the reminder message includes but is not limited to text (for example, a reminder message presented in text is output through the central control display screen), voice (for example, a reminder message presented in voice is output through the central control display screen, or the alarm sound of a buzzer is used as a reminder message), and animation (for example, a reminder message presented in animation is output through the central control display screen). Of course, in order to avoid frequent reminders to the driver, after outputting the reminder message of any of the above methods for a preset duration or a preset number of times, it will stop, or, in the case where the reminder message contains text, voice and animation reminders at the same time, if it is detected that the driver does not pay attention to the reminder message, part of the reminder message can be stopped, for example, voice reminders and animation reminders are stopped, and text reminders are retained, which not only avoids interference with the driver, but also retains the basic reminder function.

[0104] It is worth noting that the above reminder message is for the driver and belongs to an in-vehicle reminder. In a possible implementation, when it is detected that the driver is out of the seat while the vehicle is driving, it can be further detected whether there are movable objects (for example, pedestrians or other vehicles, etc.) within the preset range of the vehicle. If there are movable objects, the vehicle can also be controlled to give an outside reminder, for example, the double flash lights configured by the vehicle are controlled to flash to give an outside reminder, or the configured external display screen (the external display screen can be a light emitting diode (Light Emitting Diode, LED) screen, an organic light emitting diode (Organic Light Emitting Diode, OLED) screen, or a liquid crystal display screen) displays specific text or animation to give an outside reminder.

[0105] Of course, in the above-mentioned embodiment, the reminder inside the vehicle and the reminder outside the vehicle can be performed simultaneously, or they can be performed in sequence according to the pre-priority. For example, if it is detected that the driver is in a state of leaving the seat during the driving of the vehicle, and a movable object is detected within a preset range, the relative distance between the current vehicle and the movable object can be detected at this time. If it is determined that the relative distance has a decreasing trend, the reminder outside the vehicle and the reminder inside the vehicle can be performed in sequence during the relative distance reduction process. In other words, when the relative distance is far, the reminder outside the vehicle is given priority, so that when the movable object is far away from the current vehicle, it can be known in advance that the driver in the current vehicle has unreasonable driving behavior, so that the movable object can be better dealt with. Secondly, the reminder inside the vehicle is performed, so that when the relative distance is small, the driver of the current vehicle can be reminded in time to return to the seat for safe driving to avoid traffic accidents due to the close relative distance.
