All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present application, and the present application embodiment is not described in detail again.
Fig. 3 is a flowchart of a control method for an automobile according to an embodiment of the present application, which is illustrated by applying the control method for an automobile to an automobile, and the control method for an automobile may include the following steps:
step 301: during the driving of the automobile, the automobile monitors the driving state of the driver.
Since the driving state of the automobile is related to the driving safety of the automobile, it is necessary to monitor the driving state of the driver during the driving of the automobile.
As an example, the operation of the automobile to monitor the driving state of the driver during the driving of the automobile at least includes: acquiring the running speed of the automobile in the running process of the automobile; when the driving speed is greater than or equal to the speed threshold value, acquiring a state signal of a safety belt of a driver; when it is determined that the driver wears the safety belt based on the state signal, acquiring driving state information of the driver; when it is determined that the driver is not in the fatigue driving state based on the driving state information, it is monitored whether the driver is in the distracted driving state.
It should be noted that the speed threshold may be set in advance according to requirements, for example, the speed threshold may be 10km/h (kilometer per hour), 8km/h, and so on.
In some embodiments, when it is determined that the driver is not wearing the seatbelt based on the status signal, the driver is prompted to wear the seatbelt through the second prompt message. And when detecting that the driver still does not fasten the safety belt after the first specified time length based on the second prompt information, controlling the automatic driving system to take over the automobile and controlling the automobile to stop at the side through the automatic driving system.
It should be noted that the first specified time period may be set in advance according to requirements, for example, the first specified time period may be 10 seconds, 30 seconds, and so on.
Since the influence of the driving state of the driver on the driving safety is small when the vehicle running speed is relatively slow, the state signal of the seatbelt of the driver can be acquired when the running speed is greater than or equal to the speed threshold value. When the driver is not wearing the seat belt, the driver is already in an unsafe driving state, and therefore needs to be prompted, and when the driver is wearing the seat belt, the driving state of the driver is a main reason affecting safe driving, and therefore, the driving state information of the driver needs to be acquired.
In some embodiments, the automobile may acquire driving state information of the driver, such as eye information, head information, body behavior information, and the like, through the installed camera, and determine whether the driver is in a fatigue driving state and/or a distraction driving state according to the driving state information.
It should be noted that, for the operation of determining whether the driver is in the fatigue driving state and/or the distracted driving state according to the driving state information and the operation of controlling the vehicle to stop at the side by the automatic driving system, reference may be made to the related art, which is not described in detail in the embodiments of the present application.
In some embodiments, the operation of monitoring the driving state of the driver by the vehicle during the driving of the vehicle may include not only the above operation, but also other operations, such as acquiring the driving speed of the vehicle during the driving of the vehicle; when the travel speed is greater than or equal to the speed threshold, driving state information of the driver is acquired, and it is determined whether the driver is in a fatigue driving state and/or a distraction state based on the driving state information.
In some embodiments, the automobile may monitor the driving state of the driver during driving, or may monitor the driving state of the driver at specified time intervals. The specified time interval can be set in advance according to requirements, for example, the specified time interval can be 5 minutes, 10 minutes, 30 minutes and the like.
Step 302: the vehicle determines a fatigue level at which the fatigue driving state is in when the driver is in the fatigue driving state, and/or determines a distraction level at which the distraction driving state is in when the driver is in the distraction driving state.
When the driver is in the fatigue driving state, the driver may be in a light fatigue driving state, a medium fatigue driving state or a heavy fatigue driving state, and when the driver is in the distracted driving state, the driver may be in the light distraction driving state, the medium distraction driving state or the heavy distraction driving state, and the driving states of different degrees correspond to different control modes, so when the driver is in the fatigue driving state, the automobile needs to determine the fatigue level of the fatigue driving state, and/or when the driver is in the distracted driving state, the automobile needs to determine the distraction level of the distracted driving state.
In some embodiments, the automobile compares the driving state information of the driver with the stored multi-level state scenes, and when the similarity between the scene described by the driving state information of the driver and the reference state scene is greater than or equal to a similarity threshold value, the level corresponding to the reference state scene is determined as the fatigue level or the distraction level of the driver at present. The multi-level state scenes are used for describing state scenes corresponding to each driving fatigue level and each distraction fatigue level respectively, any one of the multi-level state scenes comprises a plurality of state scenes at the same level, and the reference state scene is any one of the state scenes.
It should be noted that the similarity threshold may be set in advance according to requirements, for example, the similarity threshold may be 99%, 95%, 90%, and so on.
In some embodiments, the vehicle may determine that the driver is in a fatigue driving state or in a distracted driving state, or that the driver is in both a driving fatigue state and a distracted driving state, since the driver is also often distracted when the driver is in a fatigue driving state.
Step 303: the automobile is controlled based on the fatigue level of the fatigue driving state and/or the distraction level of the distraction driving state.
Since the control modes performed by the vehicle are different when the fatigue level and/or the distraction level of the driver are different, the vehicle needs to be controlled based on the fatigue level of the fatigue driving state and/or the distraction level of the distraction driving state.
As an example, the operation of the automobile to control the automobile based on the fatigue level of the fatigue driving state includes: when the fatigue driving state is in a first-level fatigue state, voice and text reminding is carried out through an instrument; when the fatigue driving state is in a secondary fatigue state, voice and character reminding is carried out through an instrument, an air conditioner of the automobile is controlled to be in a cold air state, and a sound host is controlled to play designated audio; and when the fatigue driving state is in a three-stage fatigue state, simulating telephone incoming through the vehicle-mounted equipment, and prompting the driver to drive to the target parking spot.
It should be noted that the first-stage fatigue state belongs to a light fatigue state, the second-stage fatigue state belongs to a medium fatigue state, and the third-stage fatigue state belongs to a heavy fatigue state, that is, the fatigue degree of the first-stage fatigue state is lower than that of the second-stage fatigue state, and the fatigue degree of the second-stage fatigue state is lower than that of the third-stage fatigue state.
When the driver is in the first-level fatigue state, the driver is slightly tired, and the driver is prompted to pay attention to safe driving through voice and characters; when the driver is in the secondary fatigue state, the moderate fatigue of the driver is indicated, and a good prompt effect can not be achieved through voice and characters at the moment, so that on the basis of voice and character prompt, the vehicle-mounted air conditioner can be controlled to be in a cold air state, and the sound host is controlled to play specified audio, so that the fatigue degree of the driver is reduced; when the driver is in the third-level fatigue state, the driver is in the severe fatigue state, the reminding degree of the driver needs to be further increased, and under the normal condition, the driver is more interested in the incoming calls of family, company and client, so that the automobile can simulate the incoming calls of the family, the company and the client through the vehicle-mounted equipment and prompt the driver to drive to the target parking spot.
In some embodiments, the automobile can also control the air conditioner of the automobile to be in a cold air state in the process of simulating a telephone incoming call through the vehicle-mounted equipment and prompting the driver to drive to the target parking point so as to reduce the fatigue degree of the driver.
In some embodiments, when the automobile simulates a telephone call through the vehicle-mounted device, a parking point closest to the current position in the current driving direction may be searched through the vehicle-mounted map, the parking point may be determined as a target parking point, and then the driver may be prompted to drive to the target parking point.
It should be noted that the designated audio is at least one audio set in advance according to the requirement, and the designated audio may be an audio with a strong rhythm style such as dance music.
As an example, the operation of the automobile to control the automobile based on the level of distraction the distracted driving state is at includes: when the distraction driving state is in a first-level distraction state, voice and character reminding is carried out through an instrument, and the sensitivity of a front collision early warning function and a lane departure early warning function in an automatic driving system is controlled to be adjusted to the highest sensitivity; when the distraction driving state is in a secondary distraction state, voice and character reminding is carried out through an instrument, and the sensitivity of an automatic emergency braking function and a lane keeping auxiliary function in an automatic driving system is controlled to be adjusted to the highest sensitivity; and when the distraction driving state is in a three-level distraction state, taking over the automobile through the automatic driving system.
It should be noted that the primary distraction state belongs to a mild distraction state, the secondary distraction state belongs to a moderate distraction state, and the tertiary distraction state belongs to a severe distraction state, that is, the distraction degree of the primary distraction state is lower than that of the secondary distraction state, and the distraction degree of the secondary distraction state is lower than that of the tertiary distraction state.
When the driver is distracted in driving, the automobile is easy to deviate from a lane, and collision accidents such as rear-end collision and the like are easy to occur, so that when the driver is in a primary distraction state, the driver is slightly distracted, the warning can be realized through voice and characters, and in order to avoid accidents, the sensitivity of a front collision early warning function and the sensitivity of a lane deviation early warning function in the automatic driving system can be controlled to be adjusted to the highest sensitivity; when the driver is in a secondary distraction state, the distraction of the driver is serious a little, and the driver cannot notice the prompt of voice and characters at the moment, so that the safety control of the automobile can be improved, namely the sensitivity of an automatic emergency braking function and a lane keeping auxiliary function in an automatic driving system is controlled to be adjusted to the highest sensitivity; when the driver is in the three-level distraction state, the distraction of the driver is serious, so that the automatic driving system can be directly controlled to take over the automobile in order to improve the driving safety.
In some embodiments, adjusting the sensitivity of the front collision warning function in the automatic driving system for controlling the vehicle to the highest sensitivity means increasing the collision warning distance between the vehicle and the front vehicle, for example, when the front collision warning function is in a low sensitivity, the front collision warning function of the vehicle performs a warning when detecting that the distance between the vehicle and the front vehicle is less than a second distance threshold; when the sensitivity of the front collision early warning function is at the highest sensitivity, the front collision early warning function of the automobile performs early warning when detecting that the distance between the front collision early warning function and the front automobile is smaller than a third distance threshold, and the third distance threshold is larger than the second distance threshold.
Similarly, the adjustment of the sensitivity of the lane departure warning function to the highest sensitivity means reducing the lane departure warning distance of the vehicle, for example, when the lane departure warning function is in a low sensitivity, the lane departure warning function of the vehicle performs warning when detecting that the distance of the vehicle from the lane is greater than a fourth distance threshold; when the sensitivity of the lane deviation early warning function is the highest sensitivity, the automobile carries out early warning when the distance of lane deviation detection is larger than a fifth distance threshold value, and the fifth distance threshold value is smaller than a fourth distance threshold value.
Similarly, the adjustment of the sensitivity of the automatic emergency braking function to the highest sensitivity means at least one of increasing the braking speed to the highest, increasing the braking reminding distance, increasing the braking force, and the like, and the braking speed means the speed at which the automatic emergency braking function assists the driver to reduce at most.
Similarly, the adjustment of the sensitivity of the lane keeping assist function to the highest sensitivity means the reduction of the lane departure keeping distance of the automobile.
It should be noted that the second distance threshold, the third distance threshold, the fourth distance threshold, and the fifth distance threshold can be set in advance according to requirements, for example, the second distance threshold is 1 meter, 0.5 meter, and the like, and the third distance threshold is 2 meters, 1.5 meters, and the like. The fourth distance threshold is 50 centimeters, 30 centimeters, etc., and the fifth distance threshold is 20 centimeters, 10 centimeters, etc.
In some embodiments, when the driver is in the fatigue driving state, the control operation corresponding to the fatigue driving state may be performed, and the control operation corresponding to the distraction driving state may be performed, and when the driver is in the distraction driving state, the control operation corresponding to the fatigue driving state may be performed, and the control operation corresponding to the distraction driving state may be performed.
In some embodiments, the operation of the vehicle to control the vehicle based on the fatigue level of the fatigue driving state and/or the distraction level of the distraction driving state comprises: and when the fatigue state is in the highest level fatigue state or the distracted driving state is in the highest level distraction state, playing or sending first prompt information to the reference automobile, wherein the first prompt information is used for prompting the position and the state of an automobile driver, and the reference automobile is any automobile of which the distance from the current fatigue driving or distraction driving automobile of the driver is less than or equal to a first distance threshold value.
It should be noted that the highest level fatigue driving state may be the above three-level fatigue driving state, and may also be other levels of fatigue driving states; the highest level distracted driving state may be the above three-level distracted driving state, and may also be other levels of distracted driving states.
