An embodiment of the present invention provides a method for semi-adaptively controlling an electronic horn, and referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of the method for semi-adaptively controlling an electronic horn according to the present invention.
In this embodiment, the method for semi-adaptively controlling the electronic horn includes the following steps:
step S10: and when entering a semi-adaptive control state, acquiring the pressure information and the environmental information of the electronic horn under the current working condition according to the semi-adaptive control state.
It should be noted that, the execution subject of this embodiment may be a semi-adaptive control electronic horn device, and may also be other devices that can achieve the same or similar functions.
It can be understood that the semi-adaptive control state may be a state that does not completely depend on the sensor to perform mode setting, and at the same time, a driver needs to input a pressure signal, so when entering the semi-adaptive control state, pressure information and environmental information of the electronic horn under the current working condition may be acquired based on the semi-adaptive control state, and the current working condition may be various complex working conditions that the vehicle faces during the driving process, for example, working conditions on urban roads, dense people areas, and the like, which is not limited in this embodiment.
It should be understood that the environmental information may be environmental information obtained by other sensors already mounted on the automobile, including but not limited to road type information, information of traffic participants around the automobile, and the like, and the present embodiment is not limited thereto, and the pressure information may be information that identifies an input pressure value by a pressure sensor, so as to output a corresponding signal, including a pressure value and a pressure signal, where the pressure value is a pressure value that a driver presses a horn button made by the pressure sensor, and the pressure sensor reads the input pressure value.
It should be noted that fig. 3 shows a hardware structure of the electronic horn, which includes a pressure sensor, other sensors, an MCU module, a driving module, a horn coil, and a sound generating component, where the input signal required by the MCU module is two parts, one is a pressure signal output by the pressure sensor, and the other is environmental information output by the other sensors, and the MCU module stores an electronic horn control program, and executes the program according to the input electrical signal to control the electronic horn to enter a corresponding mode.
Step S20: and judging whether the road type under the current working condition is the urban traffic road type or not according to the environment information.
It can be understood that the road type under the current working condition can be determined to be the urban traffic road type or other traffic road types based on the environmental information acquired by other sensors, so as to judge whether the road type under the current working condition is the urban traffic road type.
Step S30: and if the road type of the current working condition is the urban traffic road type, controlling the electronic horn to enter a soft mode.
It should be understood that the electronic horn in the semi-adaptive control state has two basic modes, namely a soft mode and a high-speed mode, so that the electronic horn is controlled to enter the soft mode when the road type of the current working condition is the urban traffic road type.
Step S40: and judging whether the pressure information is smaller than a preset pressure threshold value or not according to the soft mode.
It should be noted that, when the electronic horn enters the soft mode, it is determined whether a pressure value corresponding to the pressure information is smaller than a preset pressure threshold, where the preset pressure threshold may be 250N, and this embodiment limits this step.
Further, after the step S40, the method further includes:
and if the pressure information is greater than or equal to the preset pressure threshold, determining the current output volume according to the first volume.
It can be understood that the first volume may be a peak value of the horn volume in the soft mode, and in a specific implementation process, the peak value of the horn volume in the soft mode may be 60dB, which is not limited in this embodiment, and therefore, if the pressure value corresponding to the pressure information is greater than or equal to 250N, it is determined that the current output volume may be 60 dB.
Step S50: and if the pressure information is smaller than the preset pressure threshold, adjusting the current output volume according to the pressure information.
It can be understood that if the pressure value corresponding to the pressure information is less than 250N, the current output volume is adjusted according to the pressure information.
It should be understood that the calculation formula for adjusting the current output volume according to the pressure information is:
where V denotes the current output volume and F denotes the pressure value.
In the embodiment, when the electronic horn enters a semi-adaptive control state, pressure information and environmental information of the electronic horn under the current working condition are acquired according to the semi-adaptive control state; judging whether the road type under the current working condition is an urban traffic road type or not according to the environmental information; if the road type of the current working condition is the urban traffic road type, controlling the electronic horn to enter a soft mode; judging whether the pressure information is smaller than a preset pressure threshold value or not according to the soft mode; and if the pressure information is smaller than the preset pressure threshold, adjusting the current output volume according to the pressure information. The accessible whistling mode is determined through the obtained current environment information and the pressure information, so that the driving safety is improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for semi-adaptively controlling an electronic horn according to a second embodiment of the present invention.

step S201, if the road type under the current working condition is not the urban traffic road type, judging whether the traffic participation number under the current working condition is larger than a preset traffic participation threshold value according to the environment information.
It can be understood that the traffic participation number is the number of traffic participants around the vehicle under the current working condition determined by the environment information, and includes the motor vehicle traffic participation number and the non-motor vehicle traffic participation number, the preset traffic participation threshold includes a preset motor vehicle traffic participation threshold and a preset non-motor vehicle traffic participation threshold, and if the road type under the current working condition is not the urban traffic road type, it can be further determined whether the traffic participation number is greater than the preset traffic participation threshold.
Further, the step S201 includes:
and if the road type under the current working condition is not the urban traffic road type, judging whether the motor vehicle traffic participation number under the current working condition is greater than a preset motor vehicle traffic participation threshold value or not according to the environment information, and judging whether the non-motor vehicle traffic participation number under the current working condition is greater than the preset non-motor vehicle traffic participation threshold value or not.
It should be understood that the number of motor vehicle traffic participation may be the number of motor vehicles within 30m around the vehicle body as the center, and the number of non-motor vehicle traffic participation may be the number of non-motor vehicles and other traffic participants within 15m around the vehicle body as the center, which is limited in this embodiment, the preset motor vehicle traffic participation threshold is determined by a threshold setting algorithm with the motor vehicle as the target, and the preset non-motor vehicle traffic participation threshold is determined by a threshold setting algorithm with the non-motor vehicle as the target, so that, in the case that the road type is not the urban traffic road type, it is determined whether the number of motor vehicle traffic participation is greater than the preset motor vehicle traffic participation threshold, and it is determined whether the number of non-motor vehicle traffic participation is greater than the preset non-motor vehicle traffic participation threshold.
It should be noted that the final threshold provided by the threshold setting algorithm is composed of two threshold portions, including a basic threshold and a specific threshold, the basic threshold is a basic value generated according to actual traffic conditions of each city motor vehicle or non-motor vehicle in our country, the value is unified in a certain area range, the specific threshold is set for a specific environment, the specific threshold is generated for the motor vehicle or non-motor vehicle according to a trip generation rate generated by land utilization in different areas and current traffic conditions of the area, and the final threshold is calculated according to a certain weight ratio by combining the current driving speed, the current running time, the current driving freedom, the driving safety, the driving comfort and the driving economy, wherein the weight ratio can be set for technicians in the field, and the embodiment does not limit the final threshold, therefore, the preset motor vehicle traffic participation threshold value with the motor vehicle as the target and the preset non-motor vehicle traffic participation threshold value with the non-motor vehicle as the target are obtained.
And S202, if the traffic participation number under the current working condition is larger than a preset traffic participation threshold value, executing the step of controlling the electronic horn to enter a soft mode.
Further, the step S202 includes:
and if the motor vehicle traffic participation number under the current working condition is larger than a preset motor vehicle traffic participation threshold value and the non-motor vehicle traffic participation number under the current working condition is larger than a preset non-motor vehicle traffic participation threshold value, executing a step of controlling the electronic horn to enter a soft mode.
It should be understood that if the number of motor vehicle traffic participation is greater than the preset motor vehicle traffic participation threshold value and the number of non-motor vehicle traffic participation is greater than the preset non-motor vehicle traffic participation threshold value, the electronic horn can be controlled to enter the soft mode, so that the driving convenience is improved, and meanwhile, the environmental pollution is reduced.
In the embodiment, whether the traffic participation number under the current working condition is larger than a preset traffic participation threshold value is judged according to the environment information by judging whether the road type under the current working condition is not the urban traffic road type; and if the traffic participation number under the current working condition is larger than a preset traffic participation threshold value, executing a step of controlling the electronic horn to enter a soft mode, thereby further improving the accuracy of the driving safety.
Referring to fig. 5, fig. 5 is a flowchart illustrating a method for semi-adaptively controlling an electronic horn according to a third embodiment of the present invention.
Based on the above semi-adaptive control electronic horn embodiment, after step S201, the method further includes:
step S2011: and if the traffic participation number under the current working condition is less than or equal to a preset traffic participation threshold value, controlling the electronic horn to enter a high-speed mode.
It can be understood that, if the number of motor vehicle traffic participation is less than or equal to the preset motor vehicle traffic participation threshold, or the number of non-motor vehicle traffic participation is less than or equal to the preset non-motor vehicle traffic participation threshold, the electronic horn may be controlled to enter the high-speed mode.
Step S2012: and judging whether the pressure information is smaller than a preset pressure threshold value according to the hypertonic mode.
It should be noted that when the electronic horn enters the high-altitude mode, two modes can be further selected, namely a normal mode and an emergency mode, wherein the default mode is the normal mode, that is, when the electronic horn enters the high-altitude mode, the default mode is the normal mode in the high-altitude mode.
It should be understood that, when the electronic horn enters the high-pressure mode, it is determined whether the pressure value corresponding to the pressure information is smaller than the preset pressure threshold, that is, whether the pressure value in the high-pressure mode is smaller than 250N.
Further, after step S2012, the method further includes:
and if the pressure information is greater than or equal to the preset pressure threshold, determining the current output volume according to a second volume.
It is understood that the first volume may be a peak value of the speaker volume in the high mode, and the peak value of the speaker volume in the high mode may be 95dB in the specific implementation process, which is not limited in this embodiment, and therefore, if the pressure value is greater than or equal to 250N, it is determined that the current output volume may be 95 dB.
Further, if the pressure information is greater than or equal to the preset pressure threshold, after determining the current output volume according to the second volume, the method further includes:
and judging whether the frequency of the pressure information which is continuously greater than or equal to a preset pressure threshold value reaches a preset frequency or not.
It can be understood that, in a specific implementation process, the preset number of times may be three, which is not limited in this embodiment, and therefore, the number of times that the pressure value corresponding to the pressure information is continuously greater than or equal to 250N is obtained, so as to determine whether the number of times that the pressure value corresponding to the pressure information is continuously greater than or equal to 250N reaches three.
And if the frequency of the pressure information which is continuously greater than or equal to the preset pressure threshold reaches the preset frequency, determining the current output volume according to the second volume, and controlling the current output volume to sound for a long time.
It should be understood that if the pressure value corresponding to the pressure information reaches three times continuously greater than or equal to 250N, that is, the driver presses the pressure sensor with a force greater than or equal to 250N for three times continuously, the electronic horn is controlled to enter the emergency mode in the high-speed mode, and then the horn automatically sounds with a peak volume of 95dB for a long time until the driver presses the horn button to exit the emergency mode for the next time.
Step S2013: and if the pressure information is smaller than the preset pressure threshold, determining the current output volume by adopting a preset strategy according to the pressure information.
It can be understood that, if the pressure value is less than 250N, the pressure information determines the current output volume by using a preset strategy, where the preset strategy may be a calculation formula for determining the current output volume by using the pressure information.
It should be noted that, the calculation formula for determining the current output volume through the pressure information is as follows:
it should be understood that, as shown in fig. 6, which is a flowchart of a procedure, it is determined whether the type of the urban traffic road is the urban traffic road by using the pressure value and the acquired environmental information, and if so, entering a soft mode and judging whether the pressure value is less than 250N, if so, the output volume is V6F/25 (dB), if not, the output volume is 60dB, and further, it is determined whether it is the type of the urban traffic road, if so, judging whether the number of the traffic participants is larger than a threshold value, if so, entering a soft mode again, if not, entering a high-speed mode, in the high-pressure mode, whether the pressure value is continuously greater than or equal to 250N for three times is judged, if yes, the peak sound volume is prolonged, if not, whether the pressure value is less than 250N is judged, if yes, the output sound volume is V19F/50 (dB), and if not, the output sound volume is 95 dB.
In the embodiment, if the traffic participation number under the current working condition is less than or equal to a preset traffic participation threshold value, the electronic horn is controlled to enter a high-activity mode; judging whether the pressure information is smaller than a preset pressure threshold value according to the hypertonic mode; if the pressure information is smaller than the preset pressure threshold, the pressure information adopts a preset strategy to determine the current output volume; if the pressure information is greater than or equal to the preset pressure threshold, determining the current output volume according to a second volume, and judging whether the frequency of the pressure information which is continuously greater than or equal to the preset pressure threshold reaches a preset frequency; and if the frequency of the pressure information which is continuously greater than or equal to the preset pressure threshold reaches the preset frequency, determining the current output volume according to the second volume, and controlling the current output volume to sound for a long time, so that the driving safety is further effectively improved.
