FIG. 4 is a flowchart of a first embodiment of an intelligent recommendation method provided by present disclosure.

In this embodiment, the intelligent recommendation method can be applied to an environment including the vehicle-mounted device 3 and the cloud server 4. For the vehicle-mounted device 3 and the cloud server 4 that need to perform intelligent recommendation, the functions for intelligent recommendation provided by this disclosure can be directly integrated on the vehicle-mounted device 3 and the cloud server 4, or in form of software development kits (SDK) running in the vehicle-mounted device 3 and the cloud server 4.

As shown in FIG. 4, the intelligent recommendation method includes the following blocks. According to different requirements, an order of the blocks in the flowchart can be changed, and some blocks can be omitted.

At block S1, the determination module 300 of the vehicle-mounted device 3 determines whether the vehicle 100 meets a preset condition. When the vehicle 100 meets the preset condition, the process goes to block S2.

In an embodiment, the vehicle 100 meeting preset conditions may include doors of the vehicle 100 being closed and/or an engine of the vehicle 100 is activated.

For example, when a door of the vehicle 100 is closed, a door lock detector of the vehicle-mounted device 3 (not shown in the figure sends a signal as to locking (hereinafter named as “lock signal”) to the vehicle-mounted device 3. Therefore, the determination module 300 can determine that the vehicle 100 meets the preset condition when the lock signal is detected. It should be noted that because passengers of the vehicle 100 may be on and off at many times, and may cause the vehicle 100 meets the preset condition at each time, then the blocks of this intelligent recommendation method can be executed at each time.

At block S2, the execution module 302 of the vehicle-mounted device 3 captures images of occupants in the vehicle 100 by using the camera module of the detection device 33, and obtains attributes of occupants in the vehicle 100 according to the captured images.

In one embodiment, the attributes of occupants in the vehicle 100 include, but are not limited to, a total number of occupants in the vehicle 100, an identity of a driver of the vehicle 100, an age and a gender of the driver. In one embodiment, the attributes of occupants in the vehicle 100 further includes identity information of each occupant, an age and a gender of each occupant, and a composition relationship of all occupants in the vehicle 100 (the composition relationship of all occupants in the vehicle 100 means a composition relationship of occupants currently in the vehicle 100).

In one embodiment, the composition relationship of all occupants in the vehicle 100 may refer to a relationship of lovers, a relationship of family, a relationship of parent-child, or another relationship such as a relationship of each being a stranger.

In this embodiment, when the vehicle 100 meets the preset condition, the execution module 302 may control the camera module of the detection device 33 to capture images of the occupants in the vehicle 100. The execution module 302 of the vehicle-mounted device 3 may determine the age and the gender of each occupant according to the captured images by using a gender and age recognition algorithm based on face of each occupant n the captured image. In one embodiment, the execution module 302 of the vehicle-mounted device 3 pre-stores in the storage device 41 the identity information of each occupant who has ever ridden in the vehicle 100, and the relationship between the occupants who have ever ridden in the vehicle 100. In one embodiment, the identity information of the occupant who have ever ridden in the vehicle 100 includes, but is not limited to, a name, a face image, a role (i.e., a driver or a passenger) of the occupant when in the vehicle 100, and a driving mode of the vehicle 100 when the occupant in the vehicle 100.

In one embodiment, driving modes of the vehicle 100 may include, but are not limited to, a normal mode, a sport mode, and a highway mode. In one embodiment, different driving modes have different requirements on power output of the vehicle 100. Wherein, the normal mode has the lowest requirement on the power output of the vehicle 100, the sport mode has a higher requirement on the power output of the vehicle 100, and the highway ode has the highest requirement on the power output of the vehicle 100.

In one embodiment, when the execution module 302 of the vehicle-mounted device 3 is not able to obtain the identity information of an occupant from the storage device 41, the execution module 302 determines that the occupant is a stranger. In one embodiment, the execution module 302 may use a face recognition algorithm to determine whether the occupant is a stranger based on a face image of the occupant pre-stored in the storage device 41 and the captured image of the occupant.

Specifically, the execution module 302 can obtain a face image of the occupant from the captured image of the occupant. When the execution module 302 recognizes that the obtained face image of the occupant does not match the face image of the occupant pre-stored in the storage device 41, the execution module 302 can determine that the occupant is a stranger. On the contrary, when the obtained face image of the occupant matches the face image of the occupant pre-stored in the storage device 41, the vehicle-mounted device 3 can determine that the occupant is an occupant who has ever ridden in the vehicle 100. Therefore, the vehicle-mounted device 3 can also obtain other identity information of a non-first-time occupant from the storage device 41 based on the obtained face image of the occupant, the other identity information of the non-first-time occupant may include the name, the role of the non-first-time occupant, the driving mode of the vehicle, and a relationship between the non-first-time occupant and other non-first-time occupants when the non-first-tine occupant previously in the vehicle 100, and the like.

In other embodiments, the execution module 302 of the vehicle-mounted device 3 may also obtain the image of the occupant in the vehicle 100 and send the obtained image of the occupant to the cloud server 4, and the cloud server 4 can confirm the attributes of occupants in the vehicle 100 based on the obtained image.

At block S3, the acquisition module 301 of the vehicle-mounted device 3 collects information as the voice (hereinafter named as “voice information”) of the occupants in the vehicle 100 using the microphone 34.

For example, when an occupant of the vehicle 100, such as a driver, says “Please recommend a nearby restaurant”, the microphone 34 can collect corresponding voice information.

At block S4, the execution module 302 of the vehicle-mounted device 3 sends the voice information to the cloud server 4 through the communication device 35.

At block S5, the receiving module 401 of the cloud server 4 receives the voice information through the communication device 43. The response module 402 of the cloud server 4 obtains a user intention by analyzing the voice information and generates recommendation information based on the user intention. The response module 402 sends the user intention and the recommendation information to the vehicle-mounted device 3 through the communication device 43.

In this embodiment, the response module 402 can first convert the voice information into text by using a voice recognition technology; and then analyze the text using an intention recognition algorithm such as a dictionary and template-based rule method to obtain the user intention.

For example, assuming that the voice information is “please recommend a nearby restaurant”, the response module 402 obtains the user intention as: “search”, “nearby restaurant” by using the intent recognition algorithm. The response module 402 obtains restaurant information within a preset distance such as 500 meters from a predetermined application (APP) such as a software of a Google map according to the user intention, namely “search” and “nearby restaurants”, and sets the restaurant information as the recommendation information.

At block S6, the acquisition module 301 of the vehicle-mounted device 3 receives the user intention and recommendation information through the communication device 35.

At block S7, the execution module 302 of the vehicle-mounted device 3 determines whether the user intention is suitable for adding the attributes of occupants in the vehicle 100. When it is determined that he user intention is not suitable for adding the attributes of occupants in the vehicle 100, the process goes to block S8. When it is determined that the user intention is suitable for adding the attributes of occupants in the vehicle 100, the process goes to block S9.

In one embodiment, the execution module 302 can determine whether the user intention is suitable for adding the attributes of occupants in the vehicle 100 in response to user input.

In one embodiment, the execution module 302 may generate a dialog box and display the dialog box on the display screen 36. The execution module 302 may determine whether the user intention is suitable for adding the attributes of occupants in the vehicle 100 according to user's selection on the dialog box.

For example, since the cloud server 4 currently recommends restaurants without considering the attributes of occupants in the vehicle 100, the recommended restaurants include many restaurants suitable for couples, but a composition relationship in the vehicle 100 is a relationship of parent-child, and such restaurant may not be a good choice. Accordingly, the user may select on the dialog and add the attributes of occupants in the vehicle 100. Of course, the execution module 302 can also determine whether the user intention is suitable for adding the attributes of occupants in the vehicle 100 by analyzing the user's voice input.

In other embodiments, the execution module 302 of the vehicle-mounted device 3 may pre-store various user intentions that are suitable for adding the attributes of occupants in the vehicle 100; when the received user intention matches any of the pre-stored user intentions, the execution module 302 determines that the received user intention is suitable for adding the attributes of occupants in the vehicle 100; when the received user intention does not match any of the pre-stored user intentions, the execution module 302 determines that the received user intention is not suitable for adding the attributes of occupants in the vehicle 100.

In this embodiment, the pre-stored user intentions may include keywords such as “restaurant”, “hotel”, or “scenic spots” which are related to human activities.

At block S8, when the user intention is not suitable for adding the attributes of occupants in the vehicle 100, the execution module 302 of the vehicle-mounted device 3 displays the recommendation information. The execution module 302 of the vehicle-mounted device 3 may also broadcast aloud the recommendation information.

For example, the execution module 302 may display the recommendation information on the display screen 36. The execution module 302 may invoke the speaker 37 to broadcast the recommendation information aloud.

At block S9, when the user intention is suitable for adding the attributes of occupants in the vehicle 100, the execution module 302 of the vehicle-mounted device 3 obtains an updated user intention by adding the attributes of occupants in the vehicle 100 to the user intention, and sending the updated user intention to the cloud server 4 through the communication device 35.

In other embodiments, the execution module 302 may obtain he updated user intention by only adding the composition relationship of all occupants in the vehicle 100 to the user intention. For example, the execution module 302 may obtain an updated user intention: “search”, “nearby restaurants”, and “parent-child” by adding the composition relationship of all occupants of the vehicle 100, such as the relationship of parent-child to the user intention. In one embodiment, if the execution module 302 only adds the composition relationship of all occupants of the vehicle 100 to the user intention, the execution module 302 may also send other attributes such as the identity information of the occupants in the vehicle 100 to the cloud server 4.

At block S10, the response module 402 of the cloud server 4 generates updated recommendation information based on the updated user intention. The response module 402 of the cloud server 4 also sends the updated recommendation information to the vehicle-mounted device 3 through the communication device 43.

For example, the response module 402 sends a number of restaurants suitable for the relationship of parent-child to the vehicle-mounted device 3 in a form of a recommendation list.

In one embodiment, the cloud server 4 pre-stores the identity information of each occupant who has ever ridded/has previously travelled in the vehicle 100, as well as preference information of each occupant.

In other embodiments, the response module 402 can obtain preference information of each occupant based on identity information of the each occupant.

In other embodiments, the response module 402 updates the recommendation information based on the updated user intention and the preference information of each occupant.

At block S11, the acquisition module 301 of the vehicle-mounted device 3 receives the updated recommendation information through the communication device 35. The execution module 302 of the vehicle-mounted device 3 can also display the updated recommendation information on the display screen 36. The execution module 302 of the vehicle-mounted device 3 can also broadcast the updated recommendation information using speaker 37.

FIG. 5 is a flowchart of a second embodiment of an intelligent recommendation method provided by present disclosure.

In this embodiment, the intelligent recommendation method can be applied to an environment including the vehicle-mounted device 3 and the cloud server 4.

The response module 402 of the cloud server 4 also sends the updated recommendation information to the vehicle-mounted device 3 through the communication device 43.

In one embodiment, the response module 402 obtains the updated user intention by adding the attributes of occupants in the vehicle 100 to the user intention.

In other embodiments, the response module 402 may only add the composition relationship of all occupants in the vehicle 100 to the user intention to obtain the updated user intention. For example, the response module 402 may add the composition relationship of all occupants in the vehicle 100, such as a relationship of parent-child, to the user intention to obtain the updated user intention such as: “search”, “nearby restaurants”, and “parent-child”.

At block S30, the obtaining module 301 of the vehicle-mounted device 3 receives the updated recommendation information through the communication device 35. The execution module 302 of the vehicle-mounted device 3 may also display the updated recommendation information on the display screen 36. The execution module 302 of the vehicle-mounted device 3 may also use the speaker 37 to broadcast the updated recommendation information.

It should be noted that a difference between the intelligent recommendation methods shown in FIG. 4 and FIG. 5 is that the intelligent recommendation method shown in FIG. 5 is that when it is determined that the user intention is suitable for adding the attributes of occupants in the vehicle 100, the cloud server 4 is used to update user intention and update recommendations based on the updated user intention. Since a computing power of the cloud server 4 is greater than that of the vehicle-mounted device 3, it can respond to the needs of the user more quickly.

FIG. 6 is a flowchart of a third embodiment of an intelligent recommendation method provided by present disclosure.

In this embodiment, the intelligent recommendation method can be applied to an environment including the vehicle-mounted device 3 and the cloud server 4. For the vehicle-mounted device 3 and the cloud server 4 that need to perform intelligent recommendation, the functions of intelligent recommendation provided by this disclosure can be directly integrated on the vehicle-mounted device 3 and the cloud server 4, or in form of software development kits (SDK) running in the vehicle-mounted device 3 and the cloud server 4.

Block S44 is the same as block S25, and details are not repeated here.

At block S45, the execution module 302 of the vehicle-mounted device 3 determines whether the user intention is suitable for adding the attributes of occupants in the vehicle 100. When it is determined that the user intention is not suitable for adding the attributes of occupants in the vehicle 100, the process goes to block S46. When it is determined that the user intention is suitable for adding the attributes of occupants in the vehicle 100, the process goes to block S47.

The determining of whether the user intention is suitable for adding the attributes of occupants in the vehicle 100 is the same as that described in the foregoing blocks S7 and S26, and thus will not be repeated here.

Block S46 is the same as block S27, and details are not repeated here.

At block S47, the execution module 302 of the vehicle-mounted device 3 captures images of the occupants in the vehicle 100 using the camera module of the detection device 33, and confirms the attributes of occupants in the vehicle 100 according to the captured images, and transmits the attributes of occupants in the vehicle 100 to the cloud server 4 via the communication device 35.

It should be noted that, in this block S47, the capturing images of the occupants in the vehicle 100 using the camera module of the detection device 33, and confirming the attributes of occupants in the vehicle 100 according to the captured images is the same as that in block S2, details will not be repeated here. Block S48 is the same as block S29, and will not be repeated here.

Block S49 is the same as block S30, and will not be repeated here.

It should be noted that a difference between the intelligent recommendation method shown in FIG. 4 and FIG. 6 is that the intelligent recommendation method shown in FIG. 6 detects the attributes of occupants in vehicle 100 only when it is determined that the attributes of occupants in the vehicle 100 are suitable for adding to the user intention. Since the vehicle-mounted device 3 does not need to detect the attributes of occupants in vehicle 100 in advance, it does not need to detect the attributes of occupants in vehicle 100 when the attributes of occupants in vehicle 100 are not suitable for adding to the user intention, thus it saves data processing resources and responding to user needs more quickly.
