Detailed Description
In order to make the object and technical effects of the present invention more apparent, embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood, however, that the following detailed description and accompanying drawings are included to illustrate the principles of the invention, and the invention is not limited to the preferred embodiments described. The scope of the invention is defined by the appended claims.
The vehicle driving assist system according to the embodiment of the invention may be mounted on or applied to a vehicle to provide an assist to a driver during running of the vehicle. The vehicle may be an internal combustion engine vehicle using an internal combustion engine as a drive source, an electric vehicle or a fuel cell vehicle using an electric motor as a drive source, a hybrid vehicle using both of the above as drive sources, or a vehicle having another drive source.
Fig. 1 is a schematic diagram of a vehicle driving assistance system according to an embodiment of the invention. As shown in fig. 1, the vehicle 1 includes a vehicle driving assist system 100. The vehicle driving assistance system 100 may be connected to and communicate with other components of the vehicle. For the sake of simplicity, well-known power and steering systems, transmission systems, etc. in vehicles are not shown in FIG. 1.
According to some embodiments of the present invention, the vehicle driving assistance system 100 includes an operation acquisition means 110, at least one operation presentation means 120, a first determination means 130, a second determination means 140, and an operation presentation control means 150. In the exemplary embodiment, vehicle driving assistance system 100 also includes information acquisition device 160, user identification device 170, and computing device 180.
The information acquisition device 160 is configured to acquire information of a user who uses the driving assistance system 100 for vehicle. In different cases, users refer to different types of users. For example, the user is a driver who drives the vehicle while the vehicle is running. When the vehicle is stopped, the user may be a learner who is familiar with the vehicle functions. According to an embodiment of the present invention, the information acquiring device 160 may be an image sensor to acquire a face image of a user, a fingerprint pressure sensor to acquire fingerprint information of the user, or a user interface to acquire ID information of the user through input of the user, for example, an in-vehicle system account or an internet account.
According to some embodiments of the present invention, the information acquisition device 160 may be a separate unit or integrated with other devices of the vehicle. In an exemplary embodiment, the information acquisition device 160 may be fixedly mounted to the vehicle. In other embodiments, the information acquisition apparatus 160 may be integrated on other external devices, such as various portable electronic devices, such as a mobile phone, a wearable smart device (e.g., smart glasses or smart bracelet), and so on.
The user recognition device 170 is configured to recognize the identity of a user who uses the vehicle driving assistance system 100. The user recognition device 170 may recognize the identity of the user through a face recognition method based on the acquired face image, or may recognize the identity of the user through a fingerprint recognition method based on the acquired fingerprint information. Furthermore, the user identification device 170 may also determine the identity of the user through the input user ID information. It should be understood that the user identification device 170 may also determine the identity of the user using various identification methods known in the art.
The operation acquisition means 110 is configured to acquire a current user operation. According to the embodiment of the present invention, the operation acquisition means 110 may acquire information related to user operations from a CAN (Controller Area Network) bus and a Flexray bus of the vehicle and various ECUs (Electronic Control units), and analyze the user operations performed by the user based on the information. The user operation includes an operation performed on a knob, a button, a lever, or the like of the vehicle, and also includes an operation performed on a liquid crystal display, a touch panel, a keyboard, or the like of the vehicle.
The operation group of the vehicle includes all the individual operations that the user of the vehicle can perform. These single operations can implement the respective functions alone or in combination with other single operations. The current user operation may include one or more individual operations in the operation group. According to an embodiment of the present invention, the current user operation includes a plurality of single operations that are continuously performed by the user at intervals of time less than a predetermined value (e.g., 1 s).
The standard operation group includes at least one standard operation (or correct operation), wherein the standard operation is defined to include at least one single operation capable of realizing a specific function. The following describes the adaptive cruise control in detail, as an example. Fig. 2 shows a schematic diagram of a joystick implementing an adaptive cruise control function. When it is desired to store the current vehicle speed at which the vehicle is traveling and let the vehicle travel at the current vehicle speed at a constant speed, the driver needs to perform the following operations: pulling the joystick downward (S1), thereby activating the adaptive cruise control; and pressing a SET button (S2) to store the desired vehicle speed. In this example, operation S1 is a single operation and operation S2 is a single operation. The standard operation includes both operations S1 and S2 to cause the vehicle to automatically travel at a desired vehicle speed, thereby reducing the driving burden on the driver.
The computing device 180 is configured to calculate a mismatch score for the current user operation and the current standard operation. Wherein the current standard operation is a standard operation required to obtain a function that the current user operation intends to realize. According to an embodiment of the present invention, the calculating means 180 may calculate the mismatch score of the current user operation and the current standard operation by using a formula or a machine learning algorithm well known in the art.
The calculation method used by the calculation device 180 is explained by way of example. The current user operation is represented as a mathematical feature, e.g., as feature ACBD or abcccccd. Where the letters A, B, C and D represent different types of single operations. ACBD indicates that single operations A, C, B and D are performed sequentially. ABCCCCD indicates that single operations A, B, C and D are performed sequentially, and single operation C is performed six times. Likewise, the current standard operation corresponding to the current user operation is represented by a mathematical feature, for example, the current standard operation is represented as a feature ABCD. The calculating means 180 may calculate a mismatch score of the current user operation ACBD and the current standard operation ABCD, for example, 40, or a mismatch score of the current user operation abccccd and the current standard operation ABCD, for example, 80, according to a formula or a machine learning algorithm.
According to an embodiment of the present invention, the computing device 180 may calculate the mismatch score based only on the current user operation without considering the historical user operations. According to yet another embodiment of the present invention, the computing device 180 may consider historical user actions, i.e., calculate a mismatch score based on both current and historical user actions. The historical user operation is a user operation performed by a function that is executed by a user before the current user operation (for example, several hours or several days ago) and is intended to realize the current standard operation. For example, if each of all historical user operations match the current standard operation, and only the current user operation does not match the current standard operation, then it may be a user malfunction.
According to an embodiment of the present invention, a mismatch score of each historical user operation and the current standard operation may be calculated, and a total mismatch score may be calculated using the mismatch scores and the mismatch scores of the current user operation and the current standard operation. And the obtained total unmatching score is the final unmatching score of the current user operation and the current standard operation. In one example, a moving average algorithm may be utilized to calculate the total mismatch score. In this algorithm, the longer the time from the current user operation, the smaller the weight of the historical user operation.
The first determination means 130 is configured to determine whether the current user operation matches the current standard operation. According to the embodiment of the present invention, the first determination means 130 determines whether the current user operation matches the current standard operation according to the final mismatch score calculated by the calculation means 180. Specifically, the first determination device 130 is configured to: when the final mismatch score of the current user operation and the current standard operation is larger than a predetermined value (or larger than or equal to the predetermined value), judging that the current user operation and the current standard operation are not matched; and when the final mismatch score is less than or equal to a predetermined value (or less than a predetermined value), determining that the current user operation matches the current standard operation.
It should be understood that the first determination device 130 may also use other methods known in the art to determine whether the current user operation matches the current standard operation. For example, the calculation means 180 is used to calculate a matching score of the current user operation and the current standard operation, and the first determination means 130 is configured to: when the matching score is smaller than a preset value, judging that the current user operation is not matched with the current standard operation; and when the matching score is greater than or equal to a predetermined value, determining that the current user operation matches the current standard operation.
The operation presentation device 120 is configured to present an operation presentation to the user. According to an embodiment of the present invention, the operation prompting device 120 may be a stationary prompting apparatus mounted on or integrated with the vehicle. In one example, the operation prompting device 120 can be a video player that can be mounted on a center console of a vehicle, a bracket of an interior rearview mirror, or other suitable location for viewing by a user via a bracket, adhesive, or the like. In another example, the operation prompting device 120 may be integrated into an on-board display of the vehicle. For example, the in-vehicle display is a navigator or a head-up display, etc.
According to an embodiment of the present invention, the operation prompting device 120 may be a vehicle-independent movement prompting apparatus. For example, the mobile prompting device is a mobile phone, a wearable smart device, or a computer, wherein the computer may be any type of portable computer such as a notebook, a tablet computer, and the like. The movement prompting device is the movement prompting device of the user who is using the vehicle and is identified by the user identifying means 170.
The second determination device 140 is configured to determine whether at least one of the operation prompting devices 120 is activated. In other words, the second determination device 140 determines whether the operation presentation device 120 is on. When the operation prompting device 120 is activated, it indicates that the user is learning the use of the vehicle through the operation prompting device 120.
The operation presentation control means 150 is configured to control at least one of the operation presentation means 120 to present an operation presentation to the user based on the determination results of the first determination means 130 and the second determination means 140, that is, the operation presentation control means 150 performs control according to whether or not the current user operation matches the current standard operation and whether or not at least one of the operation presentation means 120 is activated.
In one example, the operation prompt may prompt the user to activate the operation prompting device 120. For example, whether or not to open a dialog box of the operation presentation apparatus, for example, "whether or not to open a teaching mode" is displayed on the operation presentation apparatus 120. The user may click on the corresponding button to confirm activation of the operation prompting device 120.
In one example, the action prompt may be to prompt the user for the current standard action. The operation prompting device 120 may play the current standard operation to the user in the form of a video. The video may be multiple pieces of video, each piece of video including one or more standard operations that implement a particular function. Fig. 3 shows a schematic diagram of standard operations presented in the form of a video according to an embodiment of the invention. As shown in fig. 3, the joystick and the direction of the joystick's motion are shown in the video. Also, two standard operations to implement the reduced cruise speed function are shown in the video. It should be understood, however, that the standard operation of the present invention is not limited to video formats. For example, the operation prompting device 120 may prompt the user for an operation in the form of audio.
In one example, the operation prompt may be to send a message to the user relating to the current standard operation. The message may be sent to an operation prompting device (e.g., the user's cell phone) 120. The message may directly contain the current standard operation, for example, the message may be text information, video information, picture information, etc. expressing the current standard operation; or the message may indirectly contain the current standard operation, e.g. the message may be a link address that can link to a web page containing information of the current standard operation.
Next, control performed by the operation presentation control device 150 in different cases will be described as an example.
According to an embodiment of the present invention, the at least one operation prompting device 120 includes a fixed prompting apparatus (e.g., a video player) and a mobile prompting apparatus (e.g., a mobile phone), and the second determination means 140 is configured to determine whether the fixed prompting apparatus is activated. The operation guidance control means 150 is configured to control the fixed guidance device and/or control the mobile guidance device to provide an operation guidance to the user based on the determination results of the first determination means 130 and the second determination means 140.
In one example, if it is determined that the current user operation does not match the current standard operation and the stationary presentation device is not activated, the operation prompt control means 150 controls the stationary presentation device to prompt the user to activate the stationary presentation device (e.g., displays a "whether to turn on the tutorial mode" dialog box on the video player); and/or the operation prompt control means 150 controls the mobile prompt device to send a message containing the current standard operation to the user, for example, a message containing the current standard operation is displayed on (an application software of a mobile phone, for example, an instant messaging application software). The message is sent to the mobile prompting device of the current user identified by the user identifying means 170.
In one example, if it is determined that the current user operation does not match the current standard operation and the stationary alert device is activated, the operation alert control apparatus 150 controls the stationary alert device to alert the user of the current standard operation, for example, to play the current standard operation at least once on a video player.
In one example, if it is determined that the current user operation matches the current standard operation and the stationary presentation device is activated, the operation presentation control means 150 controls the stationary presentation device to present the other standard operations in the standard operation group to the user. The set of standard operations may include at least one standard operation in a sequential order. The other standard operation is the next standard operation after the current standard operation. For example, after how the adaptive cruise control is operated so that the vehicle speed decreases after the playback is completed, the operation prompting device 120 automatically plays back to the user how the adaptive cruise control is operated so that the vehicle speed increases.
It should be understood that the at least one operation prompting device 120 is not limited to the above embodiment. For example, the at least one operation prompting device 120 may include only one of a fixed prompting apparatus and a mobile prompting apparatus. The second determination device 140 is not limited to the above embodiment. For example, the second determining means 140 may determine whether the movement prompting device is activated. Taking a cellular phone as an example, in the case where the cellular phone is temporarily mounted on a center console of a vehicle to function as a video player, the second determination means 140 may determine whether the cellular phone is activated.
The vehicle driving assistance system 100 according to the embodiment of the invention can actively prompt the user according to the actual situation and realize interactive teaching.
According to an embodiment of the present invention, the vehicle driving assistance system 100 further includes a human interface updating device 190. Fig. 4 shows a schematic diagram of a human-machine interface updating means 190 according to an embodiment of the invention. The human interface updating device 190 includes an operation receiving unit 191, an analyzing unit 192, a calculating unit 193, and an updating unit 194. According to an exemplary embodiment, the human interface updating apparatus 190 further includes an information receiving unit 195. The units of the human interface updating device 190 may be integrated with a cloud server, and may be capable of performing data interaction with a plurality of devices (e.g., vehicles) through a communication module that supports any one of the following communication methods: 3G, 4G, Wi-Fi, etc.
The information receiving unit 195 is configured to receive user information uploaded by a plurality of devices. The user information may include at least one of ID information of the user, sex, age, and driving experience of the user, and the like.
The operation receiving unit 191 is configured to receive user operations performed by a plurality of users that satisfy a predetermined characteristic. These user operations are uploaded by multiple devices and are selected from the group of operations described above. The user operation is an operation performed by the user to realize a function of a certain standard operation. Since some users are unfamiliar with the functions of the devices, in some cases, the user operations of these users may not match the standard operations. It is determined whether the user satisfies the predetermined characteristic according to the user information received by the information receiving unit 195. The predetermined characteristic may be a characteristic related to at least one of sex, age, and driving experience of a vehicle user. For example, the predetermined characteristics are: the age is between 18 and 50 years. Alternatively, the predetermined characteristic is: the sex is male or female, in which case the predetermined characteristic has no limiting meaning, and the plurality of users satisfying the predetermined characteristic refers to all users of the plurality of devices.
The analysis unit 192 is configured to analyze whether the user operations of the plurality of users match the standard operations of the plurality of users. The method for determining whether the user operation matches the standard operation has been described in detail above, and therefore is not described herein again.
The calculating unit 193 is configured to calculate a first number of the plurality of users and a second number of a specific user of the plurality of users, the user operation of the specific user being a specific user operation that does not match the standard operation of the plurality of users.
The updating unit 194 is configured to update the human machine interface based on the first number and the second number. According to an embodiment of the present invention, the updating unit 194 is configured to update the human-machine interfaces of the respective devices (e.g., vehicles) such that the standard operations of the plurality of users are updated to the specific user operations if the ratio of the second number to the first number is greater than a predetermined value (or the ratio of the first number to the second number is less than a predetermined value). If not, the update unit 194 does not update the human-machine interface. For example, the predetermined value may be 85%, 90%, 95%, or other suitable value.
The updating unit 194 is explained by two examples. For example, when the predetermined feature has no limiting meaning and the predetermined value is 90%, if 95% of users operate according to the specific user operation ACBD instead of the standard operation ABCD, the updating unit 194 updates the human-machine interface so that the standard operation is updated to the specific user operation ACBD. After updating the human machine interface, the user is not prompted when the user is operating in accordance with the ACBD. This allows the standard operation to be determined according to the operation habits of most users, thereby enabling the users to have a good use experience.
For example, when the predetermined characteristic is gender of woman and the predetermined value is 85%, if 88% of the female users all operate the ACBD according to the specific user instead of the standard operation ABCD, the updating unit 194 updates the human-machine interface so that the standard operation of the female users is updated to the specific user operation ACBD. After updating the human machine interface, the female user is not prompted when operating in accordance with the ACBD. This allows standard operations to be determined according to the operation habits of most female users, thereby giving the users a good use experience.
Next, a driving assistance method for a vehicle according to an embodiment of the invention is described with reference to fig. 5. Fig. 5 shows a flowchart of a driving assistance method for vehicle according to an embodiment of the invention.
Referring to fig. 5, in step S210, a current user operation is acquired. The method for obtaining the current user operation has been described in detail above, and therefore is not described herein again. Then, the process proceeds to step S220.
In step S220, it is determined whether the current user operation matches the current standard operation. The method for determining whether the current user operation matches the current standard operation has been described in detail above, and therefore will not be described herein again. Then, the process proceeds to step S230.
In step S230, it is determined whether at least one of the at least one operation prompting device 120 is activated. Then, the process proceeds to step S240.
In step S240, at least one of the operation prompting devices 120 is controlled to prompt the user for an operation based on whether the current user operation matches the current standard operation and whether at least one of the at least one operation prompting device 120 is activated. The above description has described the embodiment of controlling the operation prompting device 120 in detail, and therefore, the detailed description is omitted here.
Alternatively, the step S230 of determining whether at least one of the at least one operation prompting device 120 is activated may be performed after the step S210 of acquiring the current user operation and before the step S220 of determining whether the current user operation matches the current standard operation, or may be performed before the step S210.
Additionally, the vehicle driving assist method according to the embodiment of the invention further includes calculating a mismatch score of the current user operation and the current standard operation, wherein it is determined whether the current user operation and the current standard operation match according to the calculated mismatch score. Specifically, if the mismatch score is greater than a predetermined value, it is determined that the current user operation does not match the current standard operation; and if the mismatch score is less than or equal to a predetermined value, determining that the current user operation matches the current standard operation. The method of calculating the mismatch score has been described in detail above and will not be described in detail here.
The vehicle driving assistance method can actively prompt a user according to actual conditions and realizes interactive teaching.
According to an embodiment of the present invention, the vehicle driving assistance method further includes a human-machine interface updating step S250. The human-machine interface updating step S250 includes steps S251 to S254.
