Detailed Description
Fig. 1 is a schematic flow chart of a control method of automatically adjusting a driving mode according to a specific embodiment of the present invention. As a specific embodiment of the present invention, the present embodiment provides a control method of an automatically adjusted driving mode, which is generally configured in the case of a vehicle automatically driving mode. When the vehicle is in the automatic driving mode, the automatic adjustment driving mode is automatically started, and generally, the automatic driving mode needs to ensure safe driving of the vehicle, so in the embodiment, the automatic adjustment driving mode is also adjusted based on safe driving of the vehicle.
As a specific embodiment of the present invention, the control method for automatically adjusting driving mode of the present embodiment may specifically include:
Step S100, acquiring music data currently being played in the vehicle;
step S200, obtaining music style according to the music data;
Step S300, controlling the vehicle to switch the driving mode into a driving mode matched with the music style according to the music style;
The music styles may include a comfort music style that matches the comfort driving mode and an aggressive music style that matches the aggressive driving mode.
As a specific embodiment of the present invention, in this embodiment, when the vehicle is in the comfort driving mode, the speed of the vehicle during running is the highest speed limit on the road on which the vehicle is located multiplied by a first preset value, and the acceleration of the vehicle in the normal automatic driving mode is multiplied by the first preset value, and the first preset value is 0 to 0.8. That is, when the vehicle is in the limp-home driving mode, the vehicle runs at a vehicle speed of 0.8 times or less of the highest speed limit on the road section, and the acceleration thereof is also relatively slow, which is 0.8 times or less of the acceleration of normal driving. Of course, it is preferable that the vehicle is in the limp-home mode with both the vehicle speed and acceleration between 0.5 and 0.8 of the vehicle. When the vehicle is in the limp-home driving mode, the vehicle speed is low and the acceleration is low, i.e., the entire vehicle is driven more gently.
In this embodiment, when the vehicle is in the aggressive driving mode, the speed of the vehicle is the highest speed limit on the road where the vehicle is located multiplied by the second preset value, and the acceleration of the vehicle is the acceleration in the normal automatic driving mode multiplied by the third preset value. Wherein the second preset proportion is 0.8-1, and the third preset value is 1-1.5. When the vehicle is in the aggressive driving mode, the vehicle speed is close to the highest speed limit, and the acceleration is 1-1.5 of the normal driving acceleration. At the moment, the vehicle speed is higher, the acceleration is higher, and the method is suitable for driving experience of a driving state or a driving state of a driver.
According to the control method in the embodiment, the playing music style can be obtained according to the music data currently being played in the vehicle, and then the vehicle is controlled to switch different driving modes according to the music style, so that the interaction between the vehicle and a person is more intelligent, the man-machine interaction capability is improved, the driving experience of users in different styles or under different physiological states is improved, and the driving experience of the users is improved.
Fig. 2 is a schematic flow chart of a control method of automatically adjusting a driving mode according to another specific embodiment of the present invention. As a specific embodiment of the present invention, the control method of the automatically adjusting driving mode of the present embodiment may include:
Step S400, judging whether the vehicle starts an automatic driving mode or not; if yes, step S500 is executed, and if no, the task is ended.
Step S500, determining whether a music playing device of the vehicle is on. If not, step S600 is executed, and if yes, step S100 is executed.
In step S600, the vehicle is driven in the normal automatic driving mode.
In the present embodiment, the switching of the vehicle driving mode according to the music style is performed when the automatic driving mode of the vehicle is on and the english playing device in the vehicle is also on. Because the automatic driving mode of the vehicle is automatically driven on the premise of ensuring the safety of the vehicle, the automatic driving mode of the vehicle is automatically adjusted according to the music style in the embodiment, the driving style is switched on the premise of ensuring the safety of the vehicle, and the intelligent driving is met while the safety is ensured.
Fig. 3 is a schematic flow chart of steps for deriving a music style from music data according to another specific embodiment of the invention. As a specific embodiment of the present invention, the music data of the present embodiment may include music sound wave data.
Specifically, the step S200 of the present embodiment may include:
Step S201, drawing music sound wave data into a waveform diagram;
step S202, analyzing the oscillogram to obtain the times N of occurrence of wave peaks in unit time;
step S203, comparing the times N with a preset threshold;
step S204, when the number of times N is smaller than or equal to a preset threshold value, judging that the music style is a comfortable music style;
in step S205, when the number of times N is greater than the preset threshold, it is determined that the music style is the aggressive music style.
In this embodiment, the number of times of occurrence of the peaks in the waveform diagram can effectively express the style of music. Specifically, when the number of times N is less than or equal to the preset threshold, it is indicated that the number of times of occurrence of the peak is small in a period of time, that is, the frequency of occurrence of the music peak is low, and it is determined that the music style is a pleasant music style. Conversely, when the number of times N is greater than the preset threshold, it is indicated that the number of times of occurrence of the peak is greater in a period of time, that is, the frequency of occurrence of the peak of the music is high, the music style may be determined as an aggressive music style. The preset threshold in this embodiment may be set according to the actual situation. Of course, the name of the music style, and the kind of the music style are not limited to the above-described embodiments of the present application. The number of times N can be compared with different preset thresholds, and the number of times N can be divided into three or more different styles, so that the number of times N can be set according to actual needs.
Fig. 4 is a schematic flow chart of a control method of automatically adjusting a driving mode according to still another specific embodiment of the present invention. As a specific embodiment of the present invention, step S600 of the present embodiment may further include, before the vehicle is controlled to switch the driving mode to the driving mode matching the music style according to the music style:
Step S700, acquiring environmental data around the vehicle;
step S800, judging whether the vehicle is suitable for switching driving modes according to the environmental data; if so, step S300 is performed, and if not, the process ends.
In this embodiment, to ensure that the vehicle is in a safe driving state when the vehicle switches driving modes according to the music style, it is necessary to confirm whether the vehicle is suitable for the switching mode before switching the driving modes of the vehicle. For example, if the vehicle is blocking or the vehicle is traveling slowly around the vehicle, the vehicle switching mode is not meaningful for driving the vehicle at this time, and if the vehicle is switching the aggressive mode at this time, there is a risk of collision between the vehicle and other vehicles, and the risk of the vehicle switching the driving mode is reduced.
Fig. 5 is a schematic flow chart of a control method of automatically adjusting a driving mode according to still another specific embodiment of the present invention. As a specific embodiment of the present invention, the step S800 of determining whether the vehicle is suitable for switching the driving mode according to the environmental data may include:
Step S801, judging that the vehicle is in a congested road section according to the environmental data:
If the vehicle is in a congested road section, judging that the vehicle is not suitable for switching the driving mode, and ending the process; if the vehicle is not in the congested road section, it is determined that the vehicle is suitable for switching the driving mode, and step S300 is performed.
In the present embodiment, when the vehicle is in a congested road section, it is not suitable for switching the driving mode. At this time, no matter what style the music in the vehicle is, the vehicle cannot switch the driving mode according to the music style for the purpose of driving safety.
Fig. 6 is a schematic flow chart of a control method of automatically adjusting a driving mode according to still another specific embodiment of the present invention. As a specific embodiment of the present invention, step S801 of the present embodiment may further include, after determining that the vehicle is in a congested road section according to the environmental data:
in step S802, if the vehicle is not in the congested road section, it is determined whether the vehicle is congested when the vehicle is switched to the comfort driving mode. If yes, step S803 is executed, and if not, step S300 is executed.
In step S803, the switching of the comfort driving mode is not performed.
In this embodiment, the switching of the driving mode may be performed when the vehicle is traveling on a road section where there is no congestion, but when the driving mode of the vehicle is switched to the comfort driving mode when the vehicle is traveling on some high speed or overhead, the switching to the comfort driving mode is not suitable at this time because the vehicle is lowered to cause congestion of the vehicle behind the vehicle. Specifically, determining whether the vehicle is causing congestion after the vehicle is switched to the limp-home mode may be calculated comprehensively based on the data of the speed limit and the number of vehicles already having the average speed of the vehicle behind the current vehicle.
Fig. 7 is a schematic flow chart of a control method of automatically adjusting a driving mode according to still another specific embodiment of the present invention. As a specific embodiment of the present invention, step S801 of the present embodiment may further include, after determining that the vehicle is in a congested road section according to the environmental data:
In step S804, if the vehicle is not in the congested road section, it is determined whether the vehicle is at risk of collision with other vehicles or obstacles around the vehicle when switching to the aggressive driving mode. If yes, step S805 is executed, and if not, step S300 is executed.
In step S805, the aggressive driving mode is not switched.
In this embodiment, if the vehicle is congested in front of the vehicle, or if the vehicle is more in front of the vehicle and the vehicle speed is slow, the distance between the vehicle and the front vehicle is too small due to the sudden acceleration of the vehicle speed when the vehicle is suddenly switched to the aggressive driving mode, and if the situation such as the braking of the automatic driving mode of the vehicle is delayed or the front vehicle is suddenly decelerated, the collision between the current vehicle and the front vehicle is easily caused. In this case, too, the aggressive driving mode is not suitable to be switched. Similarly, in this embodiment, after the collision risk between the vehicle and the front vehicle is evaluated, it is determined whether to switch the aggressive driving mode, and if it is not appropriate to switch the aggressive driving mode at this time, the aggressive driving mode may not be switched.
In this way, in the above two embodiments, when the vehicle is in an uncongested road section, during the automatic driving of the vehicle, when the driving mode is switched according to the music style played in the vehicle, the traffic jam on the road is avoided under the condition of ensuring the safety of the vehicle. The intelligent interaction between the driver and the vehicle is met, the driving safety is guaranteed, and meanwhile, the influence on the use of other vehicles is avoided.
As a specific embodiment of the present invention, the present embodiment also provides a control system for automatically adjusting a driving mode. The control system for automatically adjusting the driving mode may include a control device including a memory and a processor, the memory storing a control program for implementing the above control method for automatically adjusting the driving mode when the control program is executed by the processor. The processor may be a central processing unit (central processing unit, CPU for short), or a digital processing unit, or the like. The processor transmits and receives data through the communication interface. The memory is used for storing programs executed by the processor.
