fig. 2 is a flowchart of a volume calibration method of an automatic adjustment method according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
An automatic adjustment method of a vehicle navigation sound volume according to an embodiment of the present invention is described below with reference to fig. 1 to 2.
As shown in fig. 1, a method for automatically adjusting the navigation volume of a vehicle according to an embodiment of the present invention includes: the volume control sub-method comprises the following steps:
a1: receiving a command and opening a skylight;
a2: determining whether the status of the sunroof changes;
a3: the skylight position information is obtained, a volume target value is obtained, and a first difference value between the volume target value and a volume current value is calculated;
a4: and adjusting to a volume target value.
Specifically, the method for determining the volume of the vehicle is input into the whole vehicle controller or into the independent controller of the vehicle navigation, further, after receiving the skylight opening command, the opening state of the skylight is judged, after the skylight state is changed, the opening degree of the skylight is determined, further, according to the opening degree of the skylight, a volume target value is determined, after the volume target value is determined, the determined volume target value is compared with the current volume value, a difference value is obtained, and then the volume is adjusted upwards or downwards to adjust the navigation volume to the volume target value.
It can be understood that the magnitude of noise in the vehicle is significantly changed with the change of the opening of the sunroof, and thus the target volume value is changed.
The determination of the open state of the sunroof may be performed by a position sensor or may be determined by other methods input into the controller, which is not specifically described herein.
According to the automatic adjustment method for the vehicle navigation volume, disclosed by the embodiment of the invention, the volume of the vehicle navigation is more reasonable and is adjusted in real time, on one hand, in the driving process, a driver can be ensured to learn the driving state, the expected route and the like clearly, so that the driving of the driver is facilitated; on the other hand, the driver does not need to manually adjust the navigation volume of the vehicle, so that the distraction of the driver can be avoided, and the driving safety is improved.
In the specific embodiment shown in fig. 1, between A3 and A4 further includes: a31: and judging whether the passenger manually adjusts the volume, if so, carrying out A32 to acquire the current volume value again, and after obtaining a second difference value between the target volume value and the current volume value, carrying out A4, otherwise, directly carrying out A4.
It can be understood that under some driving situations or in some habits of the driver, in the process of opening the sunroof, the driver can actively adjust the vehicle navigation volume, so that the difference between the target volume value and the current volume value is changed, if the adjustment is still performed according to the expected first difference value, the volume is too large or too small, and a sub-process is further added between A3 and A4, so that after the driver manually adjusts the volume, the difference (i.e. the second difference) between the target volume value and the current volume value is redetermined, and then the vehicle navigation volume is adjusted according to the second difference value, so that the influence of environmental factors on the automatic adjustment method is reduced, and the accurate and reliable volume adjustment of the automatic adjustment method is ensured, so as to improve the use experience.
It can be understood that the judgment logic of A2 is: the sunroof position is changed by A3, and the sunroof position is not changed by a31. That is, in the sunroof position (i.e., after the sunroof opening is changed), the volume adjustment is required, and then A3 is directly performed, and on the premise that the sunroof position is not changed, it is required to determine whether the current volume value and the target volume value are consistent, so as to avoid that the volume of the vehicle navigation is too large or too small, and thus a31 is performed.
As shown in fig. 2, it can be understood that the optimal volume of the volume control sub-method is obtained by the volume calibration sub-method.
The volume calibration sub-method is suitable for calibrating the optimal volume under different target vehicle speeds and different sky window opening states.
Therefore, the optimal volume of the sunroof in the unchanged opening state and the optimal volume of the sunroof in the same vehicle speed in different opening states are calibrated through the volume calibration sub-method, so that the volume control sub-method can control the vehicle navigation to always work under the optimal volume.
In the specific embodiment shown in fig. 2, the volume calibration method includes:
S1: closing the skylight and adjusting the volume of the vehicle navigation to the minimum;
S2: enabling the vehicle to run at a target speed, and reading a noise initial value noise which is acquired by a noise sensor;
S3: adjusting the skylight to a target state, and reading a noise current value noise cur1 of the noise sensor;
S4: calculating a noise deviation delta1;
S5: closing a skylight, lifting the volume by a first gear, and reading a noise current value noise cur2 of a noise sensor;
s6: calculating a noise deviation delta2;
s7: and repeating S5-S6, obtaining the minimum value of the difference between delta1 and delta2, generating the optimal point of the environmental noise of the skylight in the target state under the target vehicle speed.
Wherein the target state comprises: first to nth states; s3 comprises the following steps: s31 adjusts the skylight to the first state, S32 adjusts the skylight to the second state … … S3N adjusts the skylight to the N state, and at the target vehicle speed, S31-S6, S32-S6 or … … S3N-S6 are repeated to obtain a first environmental noise optimal point when the skylight is in the first state to the N state.
Specifically, S2 includes: s21 a first target vehicle speed, S22 a second target vehicle speed … … S2N an N target vehicle speed, changing the target vehicle speed under the target state, and repeating S3-S6 to obtain a second environmental noise optimal point under different target vehicle speeds.
Thus, the first ambient noise optimum point is combined with the second ambient noise optimum point to map the ambient noise map.
In other words, on the premise that the vehicles keep the same speed, the optimal sound volumes (namely the optimal points of the environmental noise) of the different opening states of the sunroof are determined by the control variable method, the opening states of the sunroof are kept unchanged, the optimal sound volume points of the different speeds of the sunroof are determined to generate the map of the environmental noise, and the sound volume control sub-method is suitable for determining the optimal sound volumes according to the map of the environmental noise, so that the sound volume adjustment meets the use requirement.
