It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

The present application provides a navigation and guidance method. Referring to FIG. 1 , FIG. 1 is a schematic flowchart of the navigation and guidance method of the present application.

The embodiments of the present application also provide embodiments of the navigation guidance method. It should be noted that although the logical sequence is shown in the flowchart, in some cases, the shown or described steps. The navigation and guidance method can be applied to a computer. For the convenience of description, the following omits the execution subject to describe each step of the navigation and guidance method. The navigation and guidance method includes:

Step S110, in the navigation guidance state, obtain navigation guidance information.

When the vehicle is in the navigation guidance state, that is, the on-board navigation device or the on-board navigation software on the vehicle plans the travel route to remind the vehicle to drive according to the travel route, wherein the travel route is determined according to the vehicle's starting location and target location. In the navigation guidance state, the navigation guidance information is obtained, and the vehicle driving reference is provided according to the navigation guidance information.

Exemplarily, the navigation guidance information includes at least one of text information, numerical information, and code information. It can be understood that when the navigation guidance information is text information, that is, the driving route or driving operation is directly expressed in the navigation guidance information, for example: go straight ahead 100 meters and turn left; when the navigation guidance information is digital information, that is, the navigation guidance information indicates the orientation. The feature is a digital feature, for example: 1 stands for going straight, 2 stands for left turn, etc.; when the navigation guidance information is code information, the navigation guidance information uses codes or symbols to indicate the orientation corresponding to different driving operations, for example: L stands for left turn, R stands for If you turn right, etc., you can get the driving operation through the code in the navigation guidance information. It should be noted that the above characters, numbers or codes are only used for illustration purposes, and may also be other information, which are not specifically limited herein.

Exemplarily, referring to FIG. 2 , FIG. 1 is a schematic flowchart of the navigation and guidance system of the present application. In-vehicle navigation equipment or in-vehicle navigation software includes a path planning module, a voice reminder calculation module, and a direction-sound field conversion module. During navigation guidance, through the internal interface of the in-vehicle navigation software, call OpenAPI (Open Application Program Interface) to send Can (Controller AreaNetwork, controller Local area network) signal command, after the signal control module in the vehicle-machine system bus receives the signal command, it controls the left series sound field and the right series sound field through the audio.

Exemplarily, in the navigation guidance state, acquiring navigation guidance information includes:

Step a, in the navigation guidance state, monitor the guidance node of the navigation guidance interface;

Step b: When the data of the navigation and guidance interface corresponding to the guidance node changes, the navigation guidance information corresponding to the navigation and guidance interface is acquired.

In the navigation guidance state, monitor the guidance node of the navigation guidance interface, wherein the navigation guidance interface refers to the middle navigation guidance point of the in-vehicle navigation software, and the guidance node refers to the timing when the in-vehicle navigation software performs voice broadcast, and monitors the navigation guidance interface in real time. Data transmission. When the data of the navigation guidance interface corresponding to the guidance node changes, the navigation guidance information corresponding to the current time of the change is obtained, and the navigation guidance information is notified to the driver through voice broadcast, so that the driver can drive the vehicle according to the navigation guidance information. drive.

Exemplarily, the guide node may be set in the in-vehicle navigation software, or may be acquired from settings in the in-vehicle navigation software. It can be understood that the voice broadcast frequency of the vehicle navigation software can be obtained, and the corresponding navigation guidance information can be obtained according to the voice broadcast frequency, that is, the number of reminders of the guiding node. For example, if the guiding node can set a reminder once, then a voice broadcast is performed at the guiding node. . The guiding node can also set reminders twice, for longer distances and shorter distances. For example, when the distance to the next azimuth conversion point is m meters, the voice broadcasts once, and the voice broadcasts again when the distance to the next azimuth conversion point is n meters. , n<m, to avoid or prevent the vehicle from missing or too late to change direction at the next azimuth change point. It should be noted that when the vehicle is driving on roads of different grades, the reminder timing of the guiding node will change. In advance, make a voice broadcast in advance.

Step S120, parse the navigation guidance information, determine the distribution pattern of the sound field in the cabin according to the analyzed information, and play the navigation guidance information through the channel corresponding to the distribution pattern for the user to drive according to the navigation guidance information.

The navigation guidance information includes driving route information, driving operation instruction information, driving mileage information, etc., among which, the driving operation instruction information refers to the refined operation information when the vehicle executes the driving route information, such as the driving direction and the driving distance corresponding to the driving direction, etc. Therefore, it is necessary to analyze the navigation guidance information, and determine the driving operation instructions of the vehicle according to the analyzed information. The voice broadcast sound fields corresponding to different driving operation instructions are different, and the sound fields of different directions are used to remind the steering operation of the corresponding direction. For example, turning left can use the left sound field to broadcast, and increase the sound of the left sound field, so that the voice broadcast has a sense of direction, enhance the user's audio sound field experience, and provide users with immersive navigation services. , for people who have no sense of sound or reverse to help them receive navigation guidance information, improve the acceptance of information, and operability.

Exemplarily, the navigation guidance information includes driving operation instruction information, the navigation guidance information is analyzed, the distribution pattern of the sound field in the cabin is determined according to the analyzed information, and the sound field is played through the channel corresponding to the distribution pattern. Navigation guidance information for users to drive according to the navigation guidance information, including:

Step c, parsing the navigation guidance information to obtain the driving operation instruction information;

Step d, extracting the orientation information feature in the driving operation instruction information;

Step e: Determine the distribution pattern of the sound field in the cabin according to the feature of the orientation information, and play the navigation guidance information through the channel corresponding to the distribution pattern for the user to drive according to the navigation guidance information.

The navigation guidance information is parsed to obtain the driving operation instruction information in the navigation guidance information. During the parsing process, the characters, numbers or code information in the navigation information are converted into orientation information features. According to the obtained azimuth information characteristics, the distribution pattern of the sound field in the cockpit is determined, and the distribution pattern of the sound field includes the main sound field, that is, the sound field in the area where the sound is mainly emitted. Therefore, it is determined that the sound field corresponding to the azimuth information feature is the main sound field, and the corresponding navigation guidance information is broadcast through the main sound field voice, so that the user can drive according to the navigation guidance information.

Exemplarily, a plurality of players, such as speakers, etc., are arranged in the cockpit. Usually, the players are arranged around the cockpit to provide full-channel sound for the cockpit. When determining the sound field distribution pattern in the cockpit according to the navigation guidance information, the distribution pattern includes the main sound field. The main sound field is realized by the channel or player in the main sound field area. The sound of the main sound field is added, which is mainly used for voice broadcast of navigation guidance information. For example, if the navigation guidance information is a left turn, the main sound field is the left sound field, and the sound of the channel or player on the left side of the driver is enhanced to increase the sound field experience on the left side of the driver, so that the driver can clearly receive the navigation guidance information, And carry out corresponding driving operations according to the navigation guidance information, such as turning on the left turn signal.

It should be noted that the distribution pattern can include the main sound field and also the auxiliary sound field. The auxiliary sound field refers to the sound field other than the main sound field. When the main sound field broadcasts the navigation guidance information by voice, the auxiliary sound field can broadcast the navigation guide information by voice, or not. Carry out voice broadcast, according to the balance of the sound field, enhance the voice broadcast sound of the main sound field, and provide immersive navigation services for the driver.

Exemplarily, when a front left turn, a left turn, or a left turn needs to be performed during driving, the navigation guidance information of the corresponding scene is realized through the left series of sound fields (left front sound field, left sound field, left rear sound field) respectively. Voice broadcast. Similarly, when it is necessary to make a front right turn, a right turn, or a right U-turn, the right series of sound fields (front right sound field, right sound field, and right rear sound field) are used to realize the voice broadcast of the navigation guidance information of the corresponding scene.

Exemplarily, when it is necessary to continue driving straight during the driving process, the voice broadcast of the navigation guidance information of the corresponding scene is realized through the sound field corresponding to the full channel. It can be understood that when the azimuth information feature is straight, the voice broadcast is performed through the full sound field, and the volume feature corresponding to the channel is not adjusted.

Exemplarily, determining the distribution pattern of the sound field in the cabin according to the azimuth information feature, and playing the navigation guidance information through the channel corresponding to the distribution pattern for the user to drive according to the navigation guidance information, including:

Step e1, according to the azimuth information feature, determine the distribution pattern of the sound field in the cabin;

Step e2, adjusting the volume feature of at least one channel in the cabin based on the distribution pattern;

Step e3, based on the controlled at least one channel, play the navigation guidance information from different sound field positions, so that the user can drive according to the navigation guidance information.

The azimuth information features include the steering information of the next stage of vehicle driving, and the distribution pattern of the sound field in the cockpit is determined according to the azimuth information features. Due to the establishment of the sound field and the volume and position of the sound emitted by the players (such as speakers) in the cockpit Relevantly, players in different positions are used as a channel to provide a voice broadcast function. Therefore, the volume characteristics of at least one channel in different positions in the cockpit are adjusted based on the distribution pattern, and the volume of information broadcast through different channels is also different based on the volume characteristics. , thus, the formed sound field is also different, the sound field corresponds to the distribution pattern corresponding to the navigation guidance information, and the navigation guidance information is played through different sound field positions, so that the voice broadcast has a sense of direction corresponding to the distribution pattern, for the user or driver according to The source of the navigation guidance information is driving in the direction of driving, and avoids the potential safety hazard caused by the fact that the driver cannot judge the direction of the vehicle according to the sound due to the full-channel prompt broadcasting the navigation, but needs to look at the navigation screen.

Exemplarily, the adjusting the volume characteristic of at least one channel in the cabin based on the distribution pattern includes:

Step e21, obtaining channel adjustment data corresponding to the distribution pattern;

Step e22: Based on the channel adjustment data, optimize the volume of the at least one channel so that the sound broadcast by the at least one channel conforms to the sound field position corresponding to the distribution pattern.

The distribution mode includes the main sound field and the auxiliary sound field. Compared with the auxiliary sound field, the main sound field is the sound area that mainly broadcasts the navigation guidance information, and the required volume characteristics are greater than the volume characteristics of the channels in the auxiliary sound field. The volume feature can be zero, or data that is significantly smaller than the volume feature of the main sound field, so that the main sound field and the auxiliary sound field have obvious differences in sound perception, so that the corresponding sound field can be selected for voice navigation broadcast according to the navigation guidance information.

Exemplarily, the channel adjustment data corresponding to the distribution pattern is obtained, and the volume of at least one channel in the cockpit is optimized based on the channel adjustment data. For example, when the vehicle needs to turn left, the volume of the channel in the left sound field is x, and the volume of the other sound field is x. The channel volume is y, where x is much greater than y, and the sound field distribution pattern is determined to be the left sound field, that is, the left sound field is the main sound field and the main sound source of the voice broadcast. It can be understood that the channel volume of other sound fields is y=0 or y≠0. It can be understood that when y=0, the left sound field emits sound, and the other sound fields do not sound, then the voice broadcast is only performed on the left side of the driver to improve the The clarity of the voice broadcast; when y≠0, other sound fields sound, but the sound is lower than the left sound field, providing immersive navigation services for the driver.

It should be noted that the channel adjustment data is preset according to actual needs, which is not specifically limited here.

Therefore, based on different channel adjustment data, optimize the volume of different channels, control the sound field distribution in the cockpit, so that the sound field distribution corresponds to the navigation guidance information, use different sound fields to broadcast voice navigation, and broadcast in different directions in the cockpit , so that the voice broadcast has a sense of direction, and the accuracy of the navigation sound of the vehicle in the navigation guidance state is low, so that the user can achieve a full audio effect experience.

Exemplarily, after parsing the navigation guidance information to obtain the driving operation instruction information, the method includes:

In step f, when the orientation information feature is not extracted from the driving operation instruction information, the distribution pattern of the sound field in the cabin is determined in combination with the actual scene information in the navigation map.

When there is no orientation information feature in the parsed navigation guidance information, it is necessary to combine the actual scene information in the navigation map to determine the distribution pattern of the sound field in the cockpit. For example, if the navigation guidance information is "exit through the ramp after 200 meters", there is no obvious orientation information feature in this navigation guidance information. At this time, combined with the actual scene information of the navigation map in the in-vehicle navigation software, in the actual scene, the ramp If the entrance is located on the right side of the current driving route of the vehicle, then it is determined that driving in the right direction is necessary to make the exit ramp, and then the right sound field in the cockpit is determined as the main sound field in the distribution mode, and the navigation is broadcast by voice through the right sound field. Guidance information to remind the driver to leave through the ramp on the right ahead.

Exemplarily, the player or playback device in the cockpit may be arranged around, or may be arranged in the driver's headrest on both sides of the driver's head. The orientation information feature in the guidance information correspondingly controls the switching of the horn sound field on the left and right sides of the headrest, so that the voice can be clearly conveyed to the driver, and at the same time, it is relatively friendly to other passengers in the cockpit, reducing the impact of noise.

Compared with the prior art, the sound accuracy caused by the full-channel voice broadcast in the navigation guidance state is low, and it is difficult for the user to achieve a full audio effect experience. In the present application, the navigation guidance information is obtained in the navigation guidance state. Analyze the navigation guidance information, determine the distribution pattern of the sound field in the cabin according to the analyzed information, and play the navigation guidance information through the channel corresponding to the distribution pattern for the user to drive according to the navigation guidance information. It can be understood that the present application controls the distribution pattern of the sound field according to the navigation guidance information, and uses different sound fields to broadcast the navigation guidance information in different directions of the cockpit. Therefore, the guidance effect of enhanced navigation is carried out through the switching of different sound fields, and the accuracy of the information is improved, so that the user can achieve a full audio effect experience.
