Technical Field

[0001] The present disclosure relates to the field of vehicle test driving, and in particular to test driving effect evaluation during vehicle test driving. Background Art

[0002] In order to sell vehicles, vehicle dealerships (such as 4S stores) usually arrange vehicle test drives for vehicle consumers so that consumers who are interested in purchasing the vehicle can better experience the performance of the vehicle before purchasing the vehicle.

[0003] During the test drive, the vehicle salesperson at the vehicle dealership accompanies the consumer (hereinafter sometimes referred to as the "test drive user") to test drive the actual vehicle. During the test drive in the test drive vehicle, the vehicle salesperson will introduce the various functions of the test drive vehicle to the consumer according to the predetermined vehicle function introduction plan, such as the central control, in-car entertainment, cruise control, automatic avoidance, assisted parking, etc. of the test drive vehicle. Through the introduction of the vehicle salesperson, the consumer can understand the performance of the test drive vehicle in a more comprehensive and detailed manner. Summary of the invention

[0004] During the actual test drive, the vehicle salesperson introduces the functions of the test drive vehicle to the test drive user in the test drive vehicle. Such introduction process is usually not supervised by the management personnel of the vehicle dealership store. Therefore, it is difficult for the management personnel to grasp the actual situation of the test drive process, and the monitoring of the behavior of the vehicle salesperson during the test drive is low, and it is impossible to evaluate the introduction of the vehicle salesperson during the test drive and the corresponding test drive effect.

[0005] The present disclosure is made in view of the above circumstances, and can provide a test drive effect evaluation device, a test drive effect evaluation method and a medium, which can evaluate the test drive effect according to the conversation between the vehicle salesperson and the test drive user in the test drive vehicle, so as to better evaluate the work quality of the vehicle salesperson and restrain the work behavior of the vehicle salesperson.

[0007] According to another aspect of the present disclosure, a test drive effect evaluation method is provided, including: obtaining a conversation between a test drive user and a vehicle salesperson in a test drive vehicle; detecting keywords in the conversation that match keywords in a predetermined test drive effect evaluation table; and evaluating the test drive effect based on whether a ratio of the number of keywords in the detected conversation to the number of keywords in the test drive effect evaluation table is above a predetermined quantity threshold.

[0008] According to another aspect of the present disclosure, a computer-readable storage medium is provided, on which a computer program is stored. When the program is executed by a processor, the processor is caused to execute the method according to the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present disclosure will now be described in the following detailed description with reference to the accompanying drawings, wherein the same reference numerals throughout the drawings represent the same or similar components. It is to be understood that the drawings are not necessarily drawn to scale and that the drawings are only used to illustrate exemplary embodiments of the present disclosure and should not be considered as limiting the scope of the present disclosure. Among them:

[0015] Various exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. However, it should be understood that the description of various exemplary embodiments is merely illustrative and does not serve as any limitation to the technology of the present disclosure. Unless otherwise specifically stated, the relative arrangement, expressions and numerical values ​​of components and steps in the exemplary embodiments do not limit the scope of the present disclosure.

[0016] The management personnel of the vehicle dealership store may train the vehicle salesperson and require the vehicle salesperson to give a comprehensive introduction to the various functions of the test drive vehicle during the actual test drive with the test drive user. The management personnel may subdivide the vehicle functions to be introduced (for example, into functions related to the central control, in-car entertainment, cruise control, automatic avoidance, assisted parking, etc.) and require the vehicle salesperson to introduce each function to the test drive user.

[0017] However, as mentioned above, during the actual test drive process, the vehicle salesperson introduces the functions of the test drive vehicle to the test drive user in the test drive vehicle, and such introduction process is usually not supervised by the management personnel of the vehicle dealership store. Therefore, it is difficult for the management personnel to grasp the actual situation of the test drive process and to know whether the vehicle salesperson has introduced all the required vehicle functions, and thus it is impossible to evaluate the introduction of the vehicle salesperson during the test drive and the corresponding test drive effect.

[0018] In view of the above problems, the present disclosure proposes a test drive effect evaluation device, which obtains the conversation between the test drive user and the vehicle salesperson in the test drive vehicle and detects the keywords in the conversation to achieve the test drive effect evaluation for the vehicle salesperson. It should be understood that the "test drive effect evaluation" described in the present disclosure is an evaluation of the situation in which the vehicle salesperson introduces the vehicle functions to the test drive user during a test drive, and evaluates whether the vehicle salesperson introduces the various vehicle functions to the test drive user in accordance with predetermined requirements (such as the vehicle function introduction plan prepared in advance by the management).

[0019] The following will refer to Figure 1 A test drive effect evaluation device according to the present disclosure is described in detail.

[0020] Figure 1 FIG. 1 is a block diagram showing an exemplary configuration of a test drive effect evaluation device 1000 according to an embodiment of the present disclosure.

[0021] like Figure 1 As shown, in some embodiments, the test drive effect evaluation device 1000 may include a processor 1010. The processor 1010 of the test drive effect evaluation device 1000 provides various functions of the test drive effect evaluation device 1000. In some embodiments, the processor 1010 of the test drive effect evaluation device 1000 may be configured to execute the test drive effect evaluation method 2000 (hereinafter referred to as Figure 2 for description).

[0022] Processor 1010 may refer to various implementations of digital circuitry, analog circuitry, or mixed-signal (a combination of analog and digital) circuitry that performs functions in a computing system. Processing circuitry may include, for example, circuits such as integrated circuits (ICs), application specific integrated circuits (ASICs), portions or circuits of separate processor cores, entire processor cores, separate processors, programmable hardware devices such as field programmable gate arrays (FPGAs), and / or systems including multiple processors.

[0023] In some embodiments, the test drive effect evaluation device 1000 may further include a memory (not shown). The memory of the test drive effect evaluation device 1000 may store information generated by the processor 1010 and programs and data for the operation of the processor 1010. The memory may be a volatile memory and / or a non-volatile memory. For example, the memory may include, but is not limited to, a random access memory (RAM), a dynamic random access memory (DRAM), a static random access memory (SRAM), a read-only memory (ROM), and a flash memory.

[0024] In addition, the test drive effect evaluation apparatus 1000 may be implemented at a chip level, or may be implemented at a device level by including other external components.

[0025] The test drive effect evaluation device 1000 of the present disclosure is configured to evaluate the test drive effect according to the conversation between the vehicle salesperson and the test drive user during the vehicle test drive in the test drive vehicle. In some embodiments, the test drive effect evaluation device 1000 can be integrated into the terminal device (such as a smart phone, tablet computer, smart watch, voice recorder, etc.) carried by the salesperson. In other embodiments, the test drive effect evaluation device 1000 can be integrated into the test drive vehicle.

[0026] like Figure 1 As shown, in some embodiments, the processor 1010 of the test drive effect evaluation device 1000 may include a dialogue acquisition unit 1020, a keyword detection unit 1030 and a test drive effect evaluation unit 1040. It should be understood that Figure 1 The various units of the test drive effect evaluation device 1000 shown are only logical modules divided according to the specific functions implemented by them, and are not used to limit the specific implementation method. In actual implementation, the above modules can be implemented as independent physical entities, or can also be implemented by a single entity (for example, a processor (CPU or DSP, etc.), an integrated circuit, etc.).

[0027] Next, we will refer to Figure 1 The specific operation of each unit of the test drive effect evaluation device 1000 is described in detail.

[0028] In some embodiments, the conversation acquisition unit 1020 may be configured to acquire a conversation between a test drive user and a vehicle salesperson in a test drive vehicle.

[0029] In some embodiments, the conversation from the start of the test drive to the end of the test drive can be obtained for the evaluation of the test drive effect. The vehicle salesperson can notify the test drive effect evaluation device 1000 of the start time and the end time of the test drive. For example, the vehicle salesperson can operate the start / end button on the test drive effect evaluation device 1000 to notify the start time and the end time of the test drive. The vehicle salesperson can also notify the test drive effect evaluation device 1000 by voice wake-up, such as saying keywords such as "test drive start", "test drive end". Alternatively, the test drive effect evaluation device 1000 can also automatically detect the test drive start time and the test drive end time. For example, when the test drive effect evaluation device 1000 detects that the vehicle salesperson and / or the test drive user enters the test drive vehicle, the moment can be used as the test drive start time, and when the test drive effect evaluation device 1000 detects that the person in the test drive vehicle has left, the moment can be used as the test drive end time.

[0030] It should be understood that the above method for determining the test drive start time and the test drive end time is only an example, and those skilled in the art can design other methods for determining the test drive start time and the test drive end time according to actual conditions.

[0031] In some embodiments, when the test drive effect evaluation device 1000 is integrated into a terminal device carried by a vehicle salesperson, the conversation acquisition unit 1020 can control the terminal device (e.g., a microphone equipped with the terminal device, etc.) to collect the conversation, or can connect to the vehicle-mounted multimedia system of the test drive vehicle through a network such as the Internet of Vehicles, thereby controlling the vehicle-mounted multimedia system (e.g., a microphone of the vehicle-mounted multimedia system, etc.) to collect the conversation. In some embodiments, when the test drive effect evaluation device 1000 is integrated into a test drive vehicle, the conversation acquisition unit 1020 can control the vehicle-mounted multimedia system of the test drive vehicle to collect the conversation, or can connect to the terminal device carried by the vehicle salesperson through a network such as the Internet of Vehicles, thereby controlling the terminal device to collect the conversation.

[0032] In some embodiments, the keyword detection unit 1030 may be configured to detect keywords in the conversation acquired by the conversation acquisition unit 1020 that match keywords in a predetermined test drive effect evaluation table.

[0033] In the present disclosure, in order to evaluate the test drive effect, a test drive effect evaluation table may be predetermined. In the test drive effect evaluation table, one or more keywords that can reflect the test drive effect are stored. These keywords, for example, can reflect various aspects of vehicle functions that the management of the vehicle sales store requires the vehicle salesperson to introduce to the test drive user.

[0034] Table 1 below shows an example of a test drive effect evaluation table, in which five keywords, namely, "central control", "in-car entertainment", "cruise control", "automatic avoidance", and "assisted parking" are stored. By detecting whether the keywords recorded in the test drive effect evaluation table appear in the conversation acquired by the conversation acquisition unit 1020, it can be determined whether the vehicle salesperson has introduced the vehicle functions related to the keywords.

[0035] [Table 1]

[0036]

[0037] It should be understood that the keywords shown in Table 1 above are only examples, and other keywords can be determined according to the specific vehicle model and the corresponding vehicle functions, such as "comfortable entry", "comfortable rear seat", "spacious space", "carplay", "lane change assistance", etc. In addition, in addition to keywords, some key sentences can also be stored in Table 1. These key sentences are, for example, sentences that the management personnel of the vehicle dealer store require the vehicle sales staff to mention when introducing the vehicle functions to the test drive users. For example, for the keyword "cruise control", key sentences related to the keyword can be pre-designed, and whether the key sentence is included in the conversation can be detected to evaluate the test drive effect.

[0038] In some embodiments, the keyword detection unit 1030 may convert the conversation in voice form acquired by the conversation acquisition unit 1020 into text, and perform keyword retrieval on the converted text to determine whether the text includes keywords that match the keywords included in the test drive effect evaluation table such as Table 1. The method of converting a conversation in voice form into text may be implemented, for example, using an existing speech recognition method (such as a "speech-to-text" application interface). Alternatively, the keywords in the test drive effect evaluation table may be pre-stored as audio samples, and the keywords may be detected from the conversation in voice form using an existing voice keyword detection method. It should be understood that those skilled in the art may also use other methods to detect keywords in a conversation, and the present disclosure does not limit the specific detection method.

[0039] In some embodiments, the test drive effect evaluation unit 1040 may be configured to evaluate the test drive effect based on whether the ratio of the number of keywords in the conversation detected by the keyword detection unit 1030 to the number of keywords in the test drive effect evaluation table is above a predetermined quantity threshold.

[0040] The predetermined number threshold can be preset by the management personnel of the vehicle dealer store according to the actual situation, for example, set to 75%. When the number of keywords in the conversation reaches more than 75% of the total number of keywords in the test drive effect evaluation table, it can be considered that the salesperson has introduced most of the required vehicle functions, and the test drive effect can be evaluated as qualified.

[0041] For example, during an actual vehicle test drive, when the keyword detection unit 1030 detects that the conversation includes the four keywords "central control", "in-car entertainment", "cruise control", and "assisted parking", the number of keywords detected in the conversation is 4 (the same keyword that appears repeatedly in the conversation is counted only once), and the number of keywords in the test drive effect evaluation table shown in Table 1 is 5, so the ratio of the two is R = 4 / 5 = 80%. This ratio is higher than the quantity threshold of 75%, so the test drive effect of the salesperson in this test drive can be evaluated as qualified.

[0042] During another actual vehicle test drive, when the keyword detection unit 1030 detects that the conversation includes the three keywords "central control", "in-car entertainment", and "assisted parking", the number of keywords detected in the conversation is 3, while the number of keywords in the test drive effect evaluation table shown in Table 1 is 5, so the ratio of the two is R = 3 / 5 = 60%. This ratio is lower than the quantity threshold of 75%, so the test drive effect of the salesperson in this test drive can be evaluated as unqualified.

[0043] In some embodiments, multiple quantity thresholds may be pre-set to perform a more detailed evaluation of the test drive effect. For example, two quantity thresholds may be set, 60% and 80%, respectively. When the ratio R<60%, the test drive effect is evaluated as unqualified, when 60%≤R<80%, the test drive effect is evaluated as good, and when R≥80%, the test drive effect is evaluated as excellent.

[0044] According to the embodiments of the present disclosure, the test drive effect can be evaluated based on the conversation between the vehicle salesperson and the test drive user in the test drive vehicle, so that the work quality of the vehicle salesperson can be better evaluated and the work behavior of the vehicle salesperson can be constrained.

[0045] In some embodiments, the number of keyword occurrences corresponding to the keywords can be further stored in the test drive effect evaluation table shown in Table 1. An example of such a test drive effect evaluation table is shown in Table 2 below. As shown in Table 2, the number of keyword occurrences corresponding to the two keywords "central control" and "in-car entertainment" is 3 times, the number of keyword occurrences corresponding to the keyword "cruise control" is 2 times, and the number of keyword occurrences corresponding to other keywords is 1 time. It should be understood that the setting of the number of keyword occurrences shown in Table 2 is only an example, and those skilled in the art can set other keyword occurrences for different keywords according to the actual vehicle model or vehicle function.

[0046] [Table 2]

[0047]

[0048] The test drive effect evaluation unit 1040 may further evaluate the test drive effect according to whether the number of occurrences of the keyword in the conversation detected by the keyword detection unit 1030 is greater than the number of occurrences of the keyword detected by the corresponding tube in the test drive effect evaluation table.

[0049] For example, according to the test drive effect evaluation table shown in Table 2, for the keyword "central control", only when it appears more than 3 times in the conversation is the introduction of the vehicle functions related to "central control" considered sufficient, and then the test drive effect is evaluated as qualified. The same is true for other keywords.

[0050] The test drive effect evaluation unit 1040 can evaluate the test drive effect based on whether the following conditions are met: the ratio R of the number of keywords in the detected conversation to the number of keywords in the test drive effect evaluation table is above a predetermined quantity threshold, and the number of occurrences of the keywords in the detected conversation is greater than the number of keyword occurrences of the corresponding keywords in the test drive effect evaluation table.

[0051] Therefore, according to the present disclosure, different times of keyword appearance can be set for different keywords according to the actual requirements for the introduction of vehicle functions, and it can be detected whether the keywords appearing in the conversation have reached the required number of times, so that a more detailed evaluation of the test drive effect can be made.

[0052] In other embodiments, the ratio R' of the total number of keywords detected in the conversation (the same keyword that appears repeatedly in the conversation is also counted) to the sum of the number of keyword appearances of each keyword in the test drive effect evaluation table may also be calculated, and then the test drive effect may be evaluated based on whether the ratio R' is above a predetermined quantity threshold.

[0053] For example, during an actual vehicle test drive, when the keyword detection unit 1030 detects that the conversation includes the four keywords "central control", "in-car entertainment", "cruise control", and "assisted parking", and the number of times each keyword appears in the conversation is 3 times, 2 times, 2 times, and 1 time, respectively, the total number of keywords detected in the conversation is 3+2+2+1=8 times. The sum of the keyword occurrence times of the five keywords stored in the test drive effect evaluation table is 3+3+2+1+1=10 times, so the ratio R'=8 / 10=80%. Since the ratio R' is above the quantity threshold of 75%, the test drive effect can be evaluated as qualified.

[0054] It should be understood that a threshold different from the quantitative threshold for the ratio R described above may be preset for the ratio R' (eg, set to 70%), and the test drive effect is evaluated as qualified when the ratio R' is above the threshold.

[0055] In addition, in some embodiments, the test drive effect evaluation unit 1040 may also calculate the ratio R and the ratio R' based on the keywords in the conversation detected by the keyword detection unit 1030. The test drive effect is evaluated as qualified only when these two ratios are respectively above the corresponding thresholds.

[0056] In the above reference Figure 1 In the test drive effect evaluation device 1000 described herein, the conversation acquisition unit 1020 acquires the conversation between the test drive user and the vehicle salesperson in the test drive vehicle, and the keyword detection unit 1030 directly performs keyword detection on the conversation.

[0057] In some embodiments, the conversation acquired by the conversation acquisition unit 1020 may be further subjected to voiceprint recognition or other speech recognition operations, thereby identifying the words spoken by the vehicle salesperson in the conversation. For example, the voiceprint information of the vehicle salesperson may be pre-stored in the test drive effect evaluation device 1000, and the voiceprint information may be used to perform voiceprint recognition on the conversation acquired by the conversation acquisition unit 1020, thereby identifying the words spoken by the salesperson.

[0058] Next, the keyword detection unit 1030 may detect only the keywords in the speech spoken by the salesperson that match the keywords in the predetermined test drive effect evaluation table. The test drive effect evaluation unit 1040 may evaluate the test drive effect according to whether the ratio of the number of keywords in the detected speech to the number of keywords in the test drive effect evaluation table is above a predetermined threshold.

[0059] According to this embodiment, before keyword detection, the words spoken by the salesperson are identified in advance from the conversation, and only the keywords in the words are detected and evaluated. Thus, the interference of the test driver's words on the test drive effect evaluation is eliminated, and the reliability and accuracy of the test drive effect evaluation can be increased.

[0060] Refer to the following Figure 2 An exemplary flow chart of a test drive effect evaluation method 2000 according to an embodiment of the present disclosure is described below. The method 2000 can be used, for example, to Figure 1 The test drive effect evaluation device 1000 is shown.

[0061] like Figure 2 As shown, in step S2010, a conversation between a test drive user and a vehicle salesperson in a test drive vehicle is obtained. In step S2020, a keyword in the conversation obtained in step S2010 that matches a keyword in a predetermined test drive effect evaluation table is detected. In step S2030, the test drive effect is evaluated based on whether the ratio of the number of keywords in the conversation detected in step S2020 to the number of keywords in the test drive effect evaluation table is above a predetermined number threshold.

[0062] The above steps S2010 to S2030 can be respectively referred to as Figure 1 The details of steps S2010 to S2030 are as described in detail in reference to Figure 1 The description is similar and will not be repeated here.

[0063] Next, refer to Figure 3 The following is a block diagram of an exemplary configuration of a test drive effect evaluation device 3000 according to another embodiment of the present disclosure. Figure 1 The test drive effect evaluation device 1000 in FIG. 1 corresponds to the test drive effect evaluation device 1000 in FIG. 1 , wherein the dialogue acquisition unit 3020, the keyword detection unit 3030, and the test drive effect evaluation unit 3040 correspond to Figure 1 The dialogue acquisition unit 1020, the keyword detection unit 1030, and the test drive effect evaluation unit 1040 shown in FIG. Figure 1 Describe the corresponding functions of each unit.

[0064] like Figure 3 As shown, in some embodiments, the processor 3010 of the test drive effect evaluation device 3000 may further include a playback control unit 3050. The playback control unit 3050 may be configured to perform playback control to play introduction content related to the keywords in the test drive effect evaluation table that are not detected in the conversation detected by the keyword detection unit 3030.

[0065] For example, when the keyword detection unit 3030 detects that the conversation includes the four keywords "central control", "in-car entertainment", "cruise control", and "assisted parking", it can be seen from the comparison with the test drive effect evaluation table shown in Table 1 that the keyword "automatic avoidance" is not detected in the conversation. In this case, the playback control unit 3050 can perform playback control to play the introduction content related to the keyword "automatic avoidance". In this way, when the salesperson fails to fully introduce the required vehicle functions due to negligence or omission, the playback control unit 3050 can play the corresponding introduction content to the test drive user to make the introduction content introduced to the test drive user more complete.

[0066] In some embodiments, when the test drive evaluation device 3000 is integrated into the terminal device carried by the vehicle salesperson, the playback control unit 3050 can control the terminal device (such as the speaker equipped with the terminal device) to play, or it can be connected to the vehicle multimedia system of the test drive vehicle through a network such as the Internet of Vehicles, thereby controlling the vehicle multimedia system (such as the speaker of the vehicle multimedia system) to play. In some embodiments, when the test drive effect evaluation device 3000 is integrated into the test drive vehicle, the playback control unit 3050 can control the vehicle multimedia system of the test drive vehicle to play, or it can be connected to the terminal device carried by the vehicle salesperson through a network such as the Internet of Vehicles, thereby controlling the terminal device to play.

[0067] In some embodiments, the video can be played when the remaining test drive time of the test drive user is less than a predetermined remaining test drive time threshold. For example, when the total test drive time is 40 minutes, the remaining test drive time threshold can be set to 10 minutes in advance. When the remaining test drive time of the test drive user is less than 10 minutes, if the vehicle salesperson still does not introduce the content related to the keyword "automatic avoidance", it can be considered that the vehicle salesperson is likely to have neglected or omitted the introduction of the keyword. In this case, the playback control unit 3050 can perform playback control to supplement the corresponding introduction content to the test drive user, so that the introduction content introduced to the test drive user is more complete.

[0068] In some embodiments, alternatively or additionally, the processor 3010 of the test drive effect evaluation device 3000 may also be configured to prompt the salesperson with keywords in the test drive effect evaluation table that were not detected in the conversation. For example, the test drive effect evaluation device 3000 may notify the terminal device carried by the vehicle salesperson of the keyword "automatic avoidance" that was not detected in the conversation through voice, text, etc., to prompt the salesperson to introduce the keyword. As another example, the undetected keyword may also be displayed or played through the multimedia system of the test drive vehicle (for example, displaying the keyword on a display screen in the test drive vehicle, playing the keyword through a speaker in the test drive vehicle), to prompt the salesperson to introduce the vehicle functions related to the keyword.

[0069] Similarly, when the remaining test drive time of the test drive user for the test drive vehicle is lower than a predetermined remaining test drive time threshold, the vehicle salesperson may be prompted with keywords in the test drive effect evaluation table that were not detected in the conversation.

[0070] In some cases, due to reasons such as the windows of the test drive vehicle being open or the volume of the background music played in the test drive vehicle being increased, the noise in the test drive vehicle may become louder and affect the test drive user's listening to the introduction content controlled by the playback control unit 3050.

[0071] In this case, the playback control unit 3050 can perform playback control when the noise level in the test drive vehicle is higher than a predetermined noise threshold, so that the on-board multimedia system of the test drive vehicle and the terminal device carried by the salesperson play introductory content related to the keywords in the test drive effect evaluation form that were not detected in the conversation.

[0072] In some embodiments, when the test drive effect evaluation device 3000 is installed in the terminal device carried by the vehicle salesperson, the noise level in the test drive vehicle can be measured, for example, by a microphone or other sound sensing device equipped in the terminal device, or it can also be measured by controlling the sensor in the test drive vehicle through a network such as the Internet of Vehicles. In other embodiments, when the test drive effect evaluation device 3000 is installed in the test drive vehicle, the noise level in the test drive vehicle can be measured, for example, by a sound sensor in the test drive vehicle, or it can also be measured by controlling the microphone or other sensing device equipped in the terminal device carried by the vehicle salesperson through a network such as the Internet of Vehicles.

[0073] In this embodiment, whether to play the test drive vehicle's in-vehicle multimedia system and the terminal device carried by the salesperson together is controlled according to the noise level in the test drive vehicle. The playback volume can be adaptively changed according to the noise level, so that the test drive user can clearly hear the playback content even in a noisy environment.

[0074] In some embodiments, the playback control unit 3050 can further adjust the playback volume of the vehicle multimedia system of the test drive vehicle according to the noise level in the test drive vehicle, and / or adjust the playback volume of the terminal device carried by the vehicle salesperson. In this way, the playback volume can be dynamically adjusted according to the noise level.

[0075] In some embodiments, the playback control unit 3050 can also perform playback control so that the playback of the introductory content can be switched between the in-vehicle multimedia system of the test drive vehicle and the terminal device carried by the salesperson according to the noise level in the test drive vehicle.

[0076] In some embodiments, the vehicle salesperson may carry multiple terminal devices, or multiple vehicle salespersons may each carry a terminal device to accompany the test drive user in the test drive vehicle. In this case, the playback control unit 3050 can perform playback control according to the noise level in the test drive vehicle to control the speakers of one or more terminal devices among the multiple terminal devices to play, thereby adjusting the playback volume.

[0077] If the noise in the test drive vehicle is high, it may also affect the acquisition of the conversation between the test drive user and the vehicle salesperson in the test drive vehicle and the detection of keywords. For example, if the acquired conversation includes a large noise component, it may affect the accuracy of speech recognition of the conversation, thereby reducing the accuracy of keyword detection, and further affecting the evaluation of the test drive effect.

[0078] Therefore, in some embodiments, the conversation acquisition unit 3020 can be further configured to: when the noise level in the test drive vehicle is higher than a predetermined noise threshold, control is performed so that the in-vehicle multimedia system in the test drive vehicle and the terminal device carried by the salesperson collect the conversation together.

[0079] For example, when the test drive effect evaluation device 3000 is integrated into a terminal device carried by a vehicle salesperson, the conversation acquisition unit 3020 can, for example, control the terminal device (such as a microphone equipped with the terminal device) to collect conversations in the test drive vehicle. When the noise level in the test drive vehicle is higher than a predetermined noise threshold, collecting conversations only through the terminal device may not ensure the signal-to-noise ratio of the collected conversations. Therefore, the conversation acquisition unit 3020 can control the vehicle-mounted multimedia system (such as one or more microphones) in the test drive vehicle through a network such as the Internet of Vehicles, and collect conversations together with the terminal device. As a result, the signal-to-noise ratio of the collected conversations can be improved, thereby improving the accuracy of speech recognition and keyword detection, and further improving the accuracy of the test drive effect evaluation.

[0080] In some embodiments, the conversation acquisition unit 3020 may also control the number of microphones in the test drive vehicle to be enabled according to the noise level in the test drive vehicle. For example, when the noise is very loud, all microphones in the test drive vehicle are enabled, and when the noise is relatively small, only one or more microphones in the test drive vehicle are enabled. In addition, according to the position of the vehicle salesperson in the test drive vehicle, the microphone in the test drive vehicle that is relatively close to the vehicle salesperson may be enabled, thereby improving the signal-to-noise ratio of the vehicle salesperson's speech collection.

[0081] As another example, when the test drive effect evaluation device 3000 is integrated in the test drive vehicle, the dialogue acquisition unit 3020 can, for example, control the vehicle-mounted multimedia system (e.g., one or more microphones) of the test drive vehicle to collect dialogues in the test drive vehicle. When the noise level is higher than a predetermined noise threshold, the dialogue acquisition unit 3020 can, for example, control the terminal device (e.g., microphone) carried by the vehicle salesperson through a network such as the Internet of Vehicles to collect dialogues together with the vehicle-mounted multimedia system of the test drive vehicle. As a result, the signal-to-noise ratio of the collected dialogue can be improved, thereby improving the accuracy of speech recognition and keyword detection, and further improving the accuracy of the test drive effect evaluation.

[0082] In some embodiments, a vehicle salesperson may carry multiple terminal devices, or multiple vehicle salespersons may each carry a terminal device to accompany the test drive user in the test drive vehicle. In this case, the conversation acquisition unit 3020 may control the microphone of one or more of the multiple terminal devices to be turned on to collect the conversation in the test drive vehicle according to the noise level in the test drive vehicle.

[0083] Reference above Figure 3 The test drive effect evaluation device 3000 described is integrated into a terminal device carried by a vehicle salesperson or integrated into a test drive vehicle. It should be understood that the test drive effect evaluation device 3000 of the present disclosure can also be implemented on a server side connected to the test drive vehicle via a network such as the Internet of Vehicles.

[0084] Specifically, the conversation acquisition unit 3020 of the test drive effect evaluation device 3000 located on the server side can acquire the conversation in the test drive vehicle via a network such as the Internet of Vehicles. For example, the conversation acquisition unit 3020 can control the multimedia system (such as a microphone) in the test drive vehicle through the Internet of Vehicles to collect the conversation between the vehicle salesperson and the test drive user, and send it to the conversation acquisition unit 3020 on the server side through the Internet of Vehicles.

[0085] Next, the keyword detection unit 3030 can detect the conversation, and the test drive effect evaluation unit 3040 can evaluate the test drive effect according to the keywords in the detected conversation. In addition, the playback control unit 3050 can send the introduction content related to the keywords in the test drive effect evaluation table that are not detected in the conversation to the test drive vehicle through a network such as the Internet of Vehicles, and control the test drive vehicle (such as the multimedia system of the test drive vehicle) to play it.

[0086] In addition, the test drive effect evaluation device 3000 on the server side can also send the keywords in the test drive effect evaluation table that were not detected in the conversation to the test drive vehicle through text, voice, etc. via a network such as the Internet of Vehicles, so that the multimedia system of the test drive vehicle can display or play them (for example, displaying the keywords on the display screen in the test drive vehicle, playing the keywords through the speakers in the test drive vehicle), thereby prompting the salesperson to introduce the vehicle functions related to the keywords.

[0087] In addition, the above reference Figure 3 The other embodiments introduced can also be similarly applied to the test drive effect evaluation device 3000 implemented on the server side, which will not be described in detail here.

[0088] Refer to the following Figure 4 4000 according to another embodiment of the present disclosure. Figure 3 The test drive effect evaluation device 1000 is shown.

[0089] like Figure 4 As shown, in step S4010, a conversation between a test drive user and a vehicle salesperson in a test drive vehicle is obtained. In step S4020, keywords in the conversation obtained in step S4010 that match keywords in a predetermined test drive effect evaluation table are detected. In step S4030, the test drive effect is evaluated based on whether the ratio of the number of keywords in the conversation detected in step S4020 to the number of keywords in the test drive effect evaluation table is above a predetermined quantity threshold. In step S4040, playback control is performed to play introductory content related to keywords in the test drive effect evaluation table that are not detected in the conversation.

[0090] The above steps S4010 to S4040 can be respectively referred to as Figure 3 The steps S4010 to S4040 are implemented by the dialogue acquisition unit 3020, keyword detection unit 3030, test drive effect evaluation unit 3040, and playback control unit 3050 described in detail.
