Description

[0001] Embodiments of the present application relate to the technical field of vehicles, and in particular to a method and device for detecting an occupant leaving a seat, a vehicle control unit and a vehicle.

[0002] Currently, when a new energy vehicle is in a drivable state (i.e., a READY state), the driver needs to be reminded when it is detected that the driver is in an unseated state, so as to ensure driving safety.

[0003] In related technologies, a sensor such as an occupancy sensor is often arranged on a seat to detect whether the driver is in an unseated state, but the above method may be affected by factors such as the position of the seat and the weight of the driver, so that the occupancy sensor cannot accurately detect whether the driver is in an unseated state. Meanwhile, the additional arrangement of the occupancy sensor also increases the cost of the vehicle to some extent.

[0004] Embodiments of the present application provide a method and device for detecting an occupant leaving a seat, a vehicle control unit and a vehicle, which can accurately detect whether the driver is in an unseated state without relying on additional auxiliary equipment, and also reduces the cost of the vehicle.

[0005] In a first aspect, the embodiments of the present application provide a method for detecting an occupant leaving a seat, the method comprising:

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

[0007] Determining whether the driver is in an unseated state based on the running state parameter.

[0008] In the embodiments of the present application, when it is determined that the vehicle is in a drivable state, a running state parameter related to the driving behavior of the driver in the vehicle can be obtained. Since the running state parameter can reflect the driving behavior of the driver to some extent, the running state parameter can be used to more accurately determine whether the driver is in an unseated state. Meanwhile, since no additional auxiliary equipment such as an occupancy sensor is required in the above detection process, the cost of the vehicle is reduced.

[0009] Optionally, the running state parameter comprises one or more combinations of vehicle speed, door state, seat belt state, and lane departure state.

[0010] In the embodiments of the present application, one or more combinations of vehicle speed, door state, seat belt state, and lane departure state can be obtained to accurately determine whether the driver is in an unseated state.

[0011] ​​​Optionally, the determining whether the driver is in the leaving state based on the running state parameter comprises:

[0012] If it is determined that the door state is switched from the closed state to the open state and the safety belt state is switched from the enabled state to the disabled state, it is determined that the driver is in the leaving state.

[0013] In the embodiments of the present application, whether the driver is in the leaving state can be determined based on the combination of the door state and the safety belt state. For example, when the door state is switched from the closed state to the open state and the safety belt state is switched from the enabled state to the disabled state, it can be considered that the driver is in the leaving state.

[0014] Optionally, the determining whether the driver is in the leaving state based on the running state parameter comprises:

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

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

[0017] Optionally, the determining whether the driver is in the leaving state based on the running state parameter comprises:

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

[0019] In the embodiments of the present application, whether the driver is in the unseated state during the driving process of the vehicle can be determined 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 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 unseated state during the driving process of the vehicle.

[0020] Optionally, the method further comprises:

[0021] If it is determined that the vehicle speed is greater than the set threshold, 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, it is determined that the driver is in the unseated state during the driving process of the vehicle.

[0022] In the embodiments of the present application, whether the driver is in the unseated state during the driving process of the vehicle can be determined based on the combination of the vehicle speed, the door state, the seat belt state and the lane deviation 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 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, it can be considered that the driver is in the unseated state during the driving process of the vehicle.

[0023] Optionally, the method further comprises:

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

[0025] In the embodiments of the present application, whether the driver is in the unseated state during the driving process of the vehicle can be determined based on the combination of the vehicle speed, the door state, the seat belt state and the lane deviation 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 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, it can be considered that the driver is in the unseated state during the driving process of the vehicle.

[0026] Optionally, the method further comprises:

[0027] If it is determined that the driver is in the off-seat state, a reminder message is outputted for reminding the driver to return to the seat.

[0028] In the embodiments of the present application, as long as it is detected that the driver is in the off-seat state, whether the vehicle is in a stationary state or in a driving process, a reminder message is outputted for reminding the driver to return to the seat, so as to ensure the driving safety of the driver.

DETAILED DESCRIPTION

[0059] In order to better understand the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0060] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

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

[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 in an unattended state, so as to ensure driving safety.

[0063] In the related art, a seat sensor, such as an occupancy sensor, is often arranged on a seat to detect whether the driver is in an unseated state, but the above method may be affected by the position where the driver sits and the weight of the driver, and thus the occupancy sensor cannot accurately detect whether the driver is in an unseated state. Meanwhile, the additional arrangement of the occupancy sensor also increases the cost of the vehicle to some extent.

[0064] Therefore, the embodiments of the present application provide a method for detecting an unseated state. In the method, a running state parameter related to the driving behavior of the driver is obtained from the vehicle. Since the running state parameter can reflect the driving behavior of the driver to some extent, the running state parameter can be used to accurately determine whether the driver is in an unseated state. Meanwhile, no additional auxiliary equipment, such as an occupancy sensor, is required in the above detection process, thereby reducing the cost of the vehicle.

[0065] The technical solutions provided by the embodiments of the present application will be described below with reference to the accompanying drawings.

[0066] Please refer to Figure 1 FIG. 1 is a flowchart of a method for detecting an unseated state according to an embodiment of the present application. The method can be applied to a vehicle control unit (VCU), and the flow of the method is described as follows.

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

[0068] In the embodiments of the present application, when the vehicle is in a drivable state (i.e., READY), whether the driver is in an unseated state can be considered to be related to the driving behavior of the driver. Therefore, if the unseated state of the driver is to be detected, a running state parameter related to the driving behavior of the driver can be obtained from the vehicle.

[0069] For example, the running state parameter includes one or more combinations of the vehicle speed calculated by an electronic stability control module (ESC) according to wheel speed sensor data, the door state collected by an integrated body controller (IBC), the seat belt state collected by a sensor digital module (SDM), and the lane departure state collected by a lane departure warning (LDW) or a lane keeping assist (LKA).

[0070] Step 20: determining whether the driver is in the unattended state based on the running state parameter.

[0071] In the embodiments of the present application, since the running state parameter can reflect the driving behavior of the driver to some extent, the running state parameter can be used to accurately determine whether the driver is in the unattended state. At the same time, since no additional auxiliary equipment such as an occupancy sensor is needed in the detection process, the cost of the vehicle is reduced.

[0072] The following describes how to determine whether the driver is in the unattended state based on the running state parameter of the vehicle.

[0073] In the embodiments of the present application, whether the driver is in the unattended state can be determined based on the combination of the door state and the seat belt state in the running state parameter.

[0074] Referring to Figure 2 FIG. 1 is a flowchart of a method for determining the unattended state according to 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 unattended state.

[0076] In the embodiments of the present application, it is considered that when the vehicle is in the drivable state, the driver's normal driving behavior should be to close the door and fasten the seat belt, and be ready to drive the vehicle 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 disabled state (i.e., the seat belt is not fastened), it is considered that the driver is not on the driving seat, i.e., in the unattended state. On the contrary, if any of the above conditions is not met, it is considered that the driver is not in the unattended state.

[0077] It is worth noting that the above embodiments are applicable to determining whether the driver is in the unattended state when the vehicle is in the drivable state and has not started driving, and are also applicable to determining whether the driver is in the unattended state when the vehicle is in the drivable state and has started driving.

[0078] In some embodiments, considering that the driver is in the unattended state when not starting driving and in the driving process, the vehicle can need to output different reminders to improve the user experience of the driver. Therefore, in the embodiments of the present application, whether the driver is in the unattended state when not starting driving and in the driving process can be determined.

[0079] Scenario one: judging whether the driver is in an unattended state when the vehicle is not started.

[0080] Please refer to Figure 3 A flowchart of a method for judging an unattended state when a vehicle is not started is provided in the embodiments of the present application. Step 201 can be implemented by executing sub-step 2011.

[0081] Step 2011: 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 an unattended state when the vehicle is in a stationary state.

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

[0083] As a possible implementation, 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 an unattended state when the vehicle is in a stationary state. 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 an unattended state when the vehicle is stationary.

[0084] For example, the above-mentioned set threshold can be 2 km / h, 3 km / h, or 4 km / h, which is not particularly limited in the present application.

[0085] Scenario two: judging whether the driver is in an unattended state during driving.

[0086] Please refer to Figure 4 A flowchart of a method for judging an unattended state during vehicle driving is provided in the embodiments 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 in an unattended state during vehicle driving.

[0088] In the embodiments of the present application, whether the driver is in an unattended state during vehicle driving can be judged based on the combination of the vehicle speed, the door state and the seat belt state.

[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 a 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 leaving seat state during the driving process of the vehicle. 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 leaving seat state during the driving process of the vehicle. It should be understood that in this embodiment, it can be considered that the driver does not open 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 set threshold can be 2 km / h, 3 km / h, or 4 km / h, which is not particularly limited in the present application.

[0091] In some embodiments, when the driver is in a leaving seat state during the driving process of the vehicle, the driver's line of sight may not be focused on the front of the vehicle, which can cause lane deviation of the vehicle during driving. That is, lane deviation of the vehicle can be related to the driver being in a leaving seat state. 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 in a leaving seat state during the driving process of the vehicle.

[0092] Please refer to Figure 5 A flowchart of a method for determining a leaving seat state of a vehicle during a driving process is provided in the embodiments of the present application. Step 2012 can be 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 in a leaving seat state during the driving process of the vehicle.

[0094] In the embodiments of the present application, the combination of vehicle speed, door state, seat belt state, and lane deviation state can be used to determine whether the driver is in a leaving seat state during the driving process of the vehicle.

[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 a driving process. At this time, if 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 (i.e., the lane deviation is relatively serious, which can be considered to be caused by the driver under abnormal driving behavior), it can be considered that the driver is in a leaving seat state during the driving process 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 a leaving seat state during the driving process of the vehicle.

[0096] For example, the above-mentioned set threshold value can be 2 km / h, 3 km / h, or 4 km / h, which is not particularly limited in the present application.

[0097] In some embodiments, it is considered that the driver can get off during driving, but the door can not be in an open state, for example, the driver gets off to pick up a dropped object in the vehicle, at this time, the door does not need to be opened, and the vehicle has an automatic locking function, that is, when the vehicle speed exceeds the set threshold value, the door will be automatically locked. Therefore, in the embodiments of the present application, when judging whether the driver is in the off state during the driving of the vehicle, the door state can also not be considered.

[0098] Please refer to Figure 6 A flowchart of a method for judging the off state of a vehicle during driving provided by the embodiments of the present application is shown. Step 20 can be realized by executing sub-step 202:

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

[0100] In the embodiments of the present application, the driver can be judged to be in the off state during the driving of the vehicle based on the combination of the vehicle speed, the seat belt state, and the lane deviation state.

[0101] As a possible implementation, when the vehicle speed is greater than the set threshold value, it can be considered that the current vehicle is in the driving process, at this time, if 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 more serious, which can be considered to be caused by the driver under abnormal driving behavior), it can be considered that the driver is in the off state during the driving of the vehicle. On the contrary, if any of the above conditions (seat belt state, lane deviation state) is not met, it can be considered that the driver is not in the off state during the driving of the vehicle.

[0102] For example, the above-mentioned set threshold value can be 2 km / h, 3 km / h, or 4 km / h, which is not particularly limited in the present application.

[0103] Further, no matter whether the vehicle is in a drivable state but has not started driving (i.e. in a static state) or is in a driving process, as long as it is detected that the driver is in an unseated state, a reminder message can be outputted for reminding the driver to return to the seat, so as to ensure the driving safety of the driver, and the specific reminding content is not particularly limited in the application. The presentation mode of the reminder message includes but is not limited to text (for example, outputting a reminder message presented in text through a central control display screen), voice (for example, outputting a reminder message presented in voice through a central control display screen, or using the alarm sound of a buzzer as a reminder message), animation (for example, outputting a reminder message presented in animation through a central control display screen). Of course, in order to avoid frequent reminding of the driver, after a preset time or a preset number of the above-mentioned reminder message in any mode is outputted, it will be stopped, or in the case that 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, the voice reminder and the animation reminder are stopped, and the text reminder is reserved, which not only avoids the interference to the driver, but also retains the basic reminding function.

[0104] It is worth noting that the above-mentioned reminder message is for the driver and belongs to in-vehicle reminding. In a possible implementation, when it is detected that the driver is in an unseated state during the driving of the vehicle, it can be further detected whether there is a movable object (for example, a pedestrian or other vehicles, etc.) within a preset range of the vehicle. If there is a movable object, the vehicle can be further controlled to perform out-of-vehicle reminding, for example, the vehicle configured double flasher is controlled to flash to perform out-of-vehicle reminding, or the configured external display screen (the external display screen can be a light emitting diode (LED) screen, an organic light emitting diode (OLED) screen, or a liquid crystal display screen) displays specific text or animation to perform out-of-vehicle reminding.

[0105] Of course, in the above embodiments, the in-vehicle reminder and the out-of-vehicle reminder can be performed simultaneously, or sequentially according to a preset priority. For example, if it is detected that the driver is in an off-seat state 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 out-of-vehicle reminder and the in-vehicle reminder can be sequentially performed during the decrease of the relative distance. That is, when the relative distance is far, the out-of-vehicle reminder is preferentially performed on the movable object, so that the movable object can be aware of the unreasonable driving behavior of the driver in the current vehicle in advance when the distance between the current vehicle and the movable object is far, so that the movable object can better respond. The in-vehicle reminder is performed secondly, so that when the relative distance is small, the driver of the current vehicle can be reminded in time to return to the seat to drive safely, so as to avoid traffic accidents due to the small relative distance.
