In the process of automatic driving of a vehicle, after an event requiring human participation occurs, the driver needs to take over driving so as to switch the vehicle from the automatic driving mode to the manual mode, and therefore, the driver needs to be reminded at this time, but if the driver is improperly reminded, the driver may be scared or the driver cannot take over driving in the field, for example: when a driver is in a physiological state of fatigue or drowsiness, if the visual reminding of light is used, the reminding effect is not large, so that the driver cannot take over driving in the field, or the driver is possibly scared, when the driver is in a physiological state of emotional excitement or low emotion, if the visual reminding of light or the auditory reminding of sound is used, further stimulation may be caused to the driver, the driver is in an unpleasant condition or an irritability condition, and the driver cannot take over driving in the field, so that the probability of accidents occurring on the vehicle is increased, and the safety of the driver is reduced.
In order to solve the above problems, the present application provides a reminding method, an apparatus, a vehicle, a device, and a storage medium, in which a driver is reminded in a reminding manner matched with a physiological state of the driver, and since the driver has different responses to external reminding when the driver is in different physiological states, after the driver is reminded in the reminding manner matched with the physiological state of the driver, the acceptance of the driver to the reminding is improved, so that the probability that the driver is scared or the speed at which the driver takes over driving is improved is reduced, the probability of an accident occurring in the vehicle is reduced, and the safety of the driver is improved.
Example one
Fig. 1 is a schematic flow chart of a reminding method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
Specifically, in order to provide a prompt matching with the current physiological state of the driver to the driver when the driver is required to take over driving, the current physiological data information of the driver in the automatic driving process of the automatic driving vehicle needs to be acquired so as to grasp the current physiological state of the driver in real time, and when the current physiological data information of the driver is acquired.
It should be noted that the type of the wearable device mentioned in the embodiment of the present application may be set according to the physiological data information that needs to be obtained actually, and a specific wearable device is not specifically limited herein. Of course, the current physiological data information of the driver may also be acquired by a physiological acquisition device provided in the automatic driving vehicle, and the specific acquisition mode may be set according to actual needs, which is not limited herein.
And 102, after acquiring indication information which is sent by the automatic driving vehicle and used for indicating the driver to take over driving, determining a corresponding taking over prompt mode according to the physiological data information.
Specifically, the automatic driving vehicle may collect and analyze road conditions during automatic driving, and analyze vehicle conditions to determine whether the current road and vehicle conditions require a driver to take over driving, where the road conditions requiring the driver to take over driving may include: the conditions of the driver who needs to take over driving when the road is maintained, the road line is not clear, the road is uneven and the like can include: when the above situations are detected by the autonomous vehicle, in order to reduce traffic accidents, it is necessary to send instruction information for instructing the driver to take over driving to the reminding device, and of course, the situation that the instruction information for instructing the driver to take over driving needs to be sent when other situations occur may also be included, and the situation that the instruction information for instructing the driver to take over driving needs to be sent specifically may be set according to actual needs, for example: the driver may set a road segment that needs to take over the explanation by himself or a road segment that is automatically driven, and when the driver is driven to the road segment that needs to take over the driving, the driver sends instruction information for instructing the driver to take over the driving, or when the weather conditions and the like do not meet the requirements of automatic driving, the driver sends instruction information for instructing the driver to take over the driving, and the specific condition of sending the instruction information is not specifically limited herein.
After receiving instruction information sent by the autonomous vehicle to instruct the driver to take over driving, in order to provide a corresponding take-over prompting mode for the current physiological state of the driver, the physiological data information may be analyzed to obtain the current physiological state of the driver, so as to determine a take-over prompting mode matched with the current physiological state, for example: when the driver is in a physiological state of emotional excitement or depressed emotion, a haptic type takeover prompting method can be used, and further, the way of taking over the prompt by vibration can be used, when the driver is in the physiological state of tired or doze, the taking over prompting mode of the auditory type can be used, furthermore, the taking over prompting mode can be broadcasted by music or voice, because the outside reminding is reflected differently when the driver is in different physiological states, after the takeover reminding mode matched with the current physiological state is determined, when the driver is reminded, the method is favorable for improving the acceptance degree of the driver to the reminding, thereby being favorable for reducing the possibility that the driver is frightened or improving the speed of taking over the driving by the driver, thereby being beneficial to reducing the probability of accidents of the vehicle and improving the safety of the driver.
It should be noted that how to determine the corresponding takeover prompting mode according to the physiological data information, and the specific type of the takeover prompting mode may be set according to actual needs and scenes, which is not specifically limited herein.
103, sending a starting instruction to corresponding reminding equipment according to the takeover prompting mode so that the reminding equipment can take over driving reminding for the driver.
Specifically, after the reminding device acquires the takeover reminding mode, the reminding device can know which reminding equipment needs to be controlled to remind the driver, so that the reminding device can send a starting instruction to the reminding equipment corresponding to the takeover reminding mode, so that the corresponding reminding equipment can remind the driver according to the preset reminding mode after being started, and the started reminding equipment is equipment matched with the current physiological state of the driver, so that the acceptance degree of the driver for reminding can be improved when the reminding equipment is used for reminding the driver, the probability that the driver is scared is favorably reduced, or the speed of taking over the driver by the driver is favorably improved, the probability of accidents of a vehicle is favorably reduced, and the safety of the driver is favorably improved.
It should be noted that after determining the specific takeover prompting mode, what type of reminding device is specifically used may be set according to actual needs, for example: after determining to use this kind of takeover of vibrations to remind the mode, can take over the drive to the driver through the vibrations of seat and remind, perhaps can take over the drive to the driver through the vibrations of steering wheel and remind, for example again, after determining to use this kind of takeover of sound to remind the mode, can use the stereo set broadcast music in the automatic driving vehicle to take over the drive to remind to the driver, perhaps can use the radio in the automatic driving vehicle to report pronunciation and take over the drive to the driver and remind, what kind of reminding equipment that specifically uses carries out the warning of what kind of mode does not do not specifically limit here.
In a possible embodiment, in the step 102, a prompting manner and a prompting level may be determined according to the physiological data information, so that the prompting manner and the prompting level are used as the takeover prompting manner.
Specifically, different physiological data information can represent the current physiological state of the driver and the degree of the physiological state, so that a corresponding prompting mode and the strength degree (namely, the prompting level) of the prompting mode can be provided according to the current physiological state of the driver, for example: when it is determined that the current physiological state of the driver is an exhausted state according to the physiological data information, and the exhausted state is deep fatigue, the required takeover prompting mode at this time may include: the vibration reminding device is used for reminding by adopting vibration with relatively high vibration frequency and/or vibration intensity, so that the acceptance degree of the driver to the taking-over reminding mode executed at this time is improved, and the driver is effectively reminded, thereby further reducing the probability of accidents of the vehicle and further improving the safety of the driver.
In a possible implementation, fig. 2 is a schematic flow chart of another reminding method provided in the first embodiment of the present application, and as shown in fig. 2, when step 103 is executed, the following steps are performed:
Specifically, the reminding modes that different reminding devices go on are different, and because the power of reminding device can be adjusted, consequently after determining the suggestion mode, can determine corresponding reminding device, when sending the start instruction to this reminding device, can carry the warning grade in this start instruction to this reminding device is according to this warning grade adjustment power, so that the warning of output corresponding degree, for example: when the prompting mode is a seat, the prompting level is a second level, after the seat receives a starting instruction carrying the prompting level as the second level, the seat can vibrate at the best vibration frequency and/or vibration intensity corresponding to the second-level vibration so as to prompt a driver to take over, the prompting mode matched with the current physiological state can be provided for the driver through the mode, the prompting intensity corresponding to the degree of the current physiological state can be provided for the driver, the acceptance degree of the driver to the taking over prompting mode executed at this time is improved, effective prompting is achieved for the driver, the probability of accidents occurring to the vehicle is further reduced, and the safety of the driver is further improved.
In one possible embodiment, the physiological data information includes:
first data information related to a heart rate value of the driver and second data information indicating a brain wave waveform of the driver.
Specifically, the first data information related to the heart rate value of the driver may be the heart rate value of the driver, the heart rate value may be measured through an electronic bracelet or a wristwatch capable of testing the heart rate, and the second data information indicating the brain wave waveform of the driver may be obtained through a head-mounted brain wave test state test.
It should be noted that, the specific first data information may be set according to actual needs, for example: the first data information may be a blood flow rate or the like, the specific type of the first data information and the specific apparatus for measuring the first data information may be set according to the specific type of the first data information, and the specific type of the second data information and the specific apparatus for measuring the second data information may be set according to actual needs, and are not particularly limited herein.
In one possible embodiment, the step of determining the prompting mode and the reminding level according to the physiological data information can be realized by the following two steps:
a first part: judging whether the heart rate value of the driver is larger than a heart rate threshold value or not according to the first data information; when the heart rate value of the driver is larger than the heart rate threshold value, determining that the prompt mode is a tactile prompt mode; and when the heart rate value of the driver is smaller than or equal to the heart rate threshold value, determining that the prompt mode is an auditory prompt mode.
And a second part, determining a first similarity between the brain wave waveform of the driver and the α wave waveform and a second similarity between the brain wave waveform of the driver and the delta wave waveform according to the second data information, determining the reminding level to be a preset first level when the first similarity is greater than the second similarity, and determining the reminding level to be a preset second level when the first similarity is less than the second similarity, wherein the reminding intensity of the first level is slightly higher than that of the second level.
Specifically, for normal people, the normal heart rate value is generally within a value interval, when the heart rate value of the driver is within the value interval, it indicates that the driver is currently in a relatively calm state, when the driver is reminded by the outside, the driver does not show an overstimulation reaction, and when the outside is reminded by an auditory sense, the driver is relatively easy to accept, when the heart rate value of the driver is higher than the maximum value of the value interval, the driver is generally in a state of being excited or excited, at this time, the driver is not easy to receive the interference of sound, otherwise, the overstimulation reaction may occur, at this time, the driver is relatively easy to accept the tactile sense prompt, therefore, the maximum value of the value interval where the normal heart rate of the driver is located can be set as the heart rate threshold, when the heart rate value of the driver is greater than the heart rate threshold, the driver can be reminded by using a tactile prompt manner, when this driver's heart rate numerical value is less than or equal to this heart rate threshold value, can use the sense of hearing to remind the mode, the warning mode of confirming through above-mentioned mode is received by the driver more easily, and can not make the driver appear the overstimulation reaction.
The brain waves of the brain under different states are different, for example, when a person is in a relatively calm state such as waking state and quiet state, the waveform of the brain wave generated by the brain is relatively close to the waveform of α waves, when the person is in a relatively tired state, sleeping state and the like, the waveform of the brain wave generated by the brain is relatively close to the waveform of delta waves, so that the current state of the driver can be judged by judging whether the waveform of the brain wave α wave generated by the driver is more similar or more similar to the waveform of the delta waves to determine which kind of the brain wave currently generated by the driver belongs, when the waveform of the brain wave of the driver is more close to the waveform of the α waves, the driver is relatively awake, the driver can feel by using relatively small stimulation, and when the waveform of the brain wave of the driver is more close to the waveform of the delta waves, the consciousness state of the driver is relatively fuzzy, and the driver can feel by using relatively large stimulation.
Further, what kind of reminding mode that needs to be used can be confirmed through heart rate numerical value and reminds the driver, after confirming concrete reminding mode, confirm through the brain wave waveform of driver and need to use what kind of intensity under this reminding mode to remind the driver to can provide the takeover reminding mode with current physiological state assorted for the driver, promptly: not only can select the reminding device that accords with current physiological state for the driver, can also set up this reminding device to set up the warning intensity that accords with current physiological state, through above-mentioned mode, can improve this driver to this takeover suggestion mode's of execution acceptance degree, and play effectual warning to this driver, thereby further reduce the probability that the accident appears in the vehicle, and further improve driver's security.
