In view of the problem that the experience evaluation method in the related art mentioned in the above background technology cannot form a complete evaluation system, and thus cannot accurately evaluate the user's true feelings, the present application provides a vehicle experience evaluation method, in which the target test scene and the evaluation user of the vehicle to be evaluated are determined, and the evaluation user's perception result of the vehicle to be evaluated is obtained based on the target test scene, and the vehicle to be evaluated is scored to obtain the subjective evaluation result of the vehicle to be evaluated, and the evaluation user's eye tracking information of the vehicle to be evaluated is obtained to obtain the objective evaluation result of the vehicle to be evaluated, and the comprehensive evaluation result of the vehicle to be evaluated is obtained based on the subjective evaluation result and the objective evaluation result. Thus, the problem that the experience evaluation method in the related art cannot form a complete evaluation system, and thus cannot accurately evaluate the user's true feelings, etc. is solved, and the subjective evaluation of the vehicle is formed through the user's five senses and the user's eye tracking information of the vehicle is formed to form the user's objective evaluation of the vehicle, thereby obtaining the user's comprehensive evaluation of the vehicle experience evaluation.

[0050] Specifically, Figure 1 A flow chart of a vehicle experience evaluation method provided in an embodiment of the present application.

[0051] like Figure 1 As shown, the vehicle experience evaluation method includes the following steps:

[0052] In step S101, a target test scenario of a vehicle to be evaluated and an evaluation user who will evaluate the vehicle to be evaluated are determined.

[0053] Specifically, in order to solve the problem that the vehicle experience evaluation method in the related art cannot form a complete evaluation system and thus cannot accurately evaluate the user's real feelings, the embodiment of the present application forms a subjective evaluation of the vehicle to be evaluated through the user's five senses and the user's eye tracking information of the vehicle to be evaluated to form the user's objective evaluation of the vehicle to be evaluated, and then obtains the user's comprehensive evaluation of the experience evaluation of the vehicle to be evaluated based on the user's subjective evaluation and objective evaluation.

[0054] Specifically, in the user's subjective evaluation of the vehicle to be evaluated, evaluation preparation is first required, such as determining the target test scenario of the vehicle to be evaluated and the evaluation users who will evaluate the vehicle to be evaluated, wherein the target test scenario can include any road scenario where the user drives to the destination, and the evaluation users can be composed of professional evaluators and non-professional evaluators, with a minimum of 24 participants, and check the working of various functions of the vehicle system, including the steering wheel, Bluetooth, navigation map, audio, central control screen, instrumentation, network, etc. of the vehicle to be evaluated. After determining the target test scenario of the vehicle to be evaluated and the evaluation users who will evaluate the vehicle to be evaluated, an experience evaluation of the vehicle to be evaluated is conducted.

[0055] In step S102, the perception result of the evaluation user on the vehicle to be evaluated is obtained based on the target test scenario, and the vehicle to be evaluated is scored according to the perception result to obtain a subjective evaluation result of the vehicle to be evaluated.

[0056] According to one embodiment of the present application, the evaluation user's perception results of the vehicle to be evaluated are obtained based on the target test scenario, and the vehicle to be evaluated is scored according to the perception results, including: generating a corresponding target test task based on the target test scenario; obtaining and recording the evaluation user's operation time, operation mode, number of invalid operations, number of operation errors, and total time to complete the target test task for the target test task; and obtaining the evaluation user's perception results based on the target test task's operation time, operation mode, number of invalid operations, number of operation errors, and total time to complete the target test task.

[0057] Specifically, when conducting a subjective evaluation of the evaluation user, the embodiment of the present application mainly includes the perception results of the evaluation user, wherein the perception results are composed of multiple first indicator data and multiple second indicator data in each first indicator data, wherein the multiple first indicator data include the evaluation user's tactile indicator data, auditory indicator data, olfactory indicator data, visual indicator data and comprehensive perception indicator data of the vehicle to be evaluated. In other words, the perception results of the evaluation user mainly include the evaluation user's tactile, auditory, olfactory, visual and comprehensive perception of the vehicle to be evaluated, and correspond to the five dimensions of the evaluation user's experience of ease of use, good hearing, good smell, good appearance and good liking, so as to evaluate the process speed, page interaction, buttons, navigation, Bluetooth, air conditioning, interface aesthetics, clarity, color, size, sound effects, voice, cabin smell, ease of use, pleasure of use and other aspects of the vehicle to be evaluated.

[0058] According to one embodiment of the present application, a vehicle to be evaluated is scored based on the perception results, including: obtaining a scoring result of the first indicator data corresponding to each second indicator data based on the product of each second indicator data and a weight coefficient of each second indicator data, so as to obtain a scoring result of the vehicle to be evaluated based on the scoring result of the first indicator data.

[0059] Specifically, the embodiment of the present application is performed and recorded in the form of a target test task corresponding to a target test scenario, so as to perform a score after obtaining the perception results of the evaluation user on the vehicle to be evaluated based on the target test scenario.

[0060] For example, in the process of evaluating the vehicle to be evaluated by the embodiment of the present application, first, a target test scene is set to generate a target test task corresponding to the target test scene. For example, the target test scene is set to "xx airport" through the navigation system, and charging piles are searched along the way. At this time, the evaluation user records the operation time, operation mode, number of invalid operations, number of operation errors and total time to complete the target test task for the target test task. If it is a dynamic test, the number of head turns needs to be recorded; secondly, the perception result of the evaluation user is obtained according to the obtained operation time, operation mode, number of invalid operations, number of operation errors and total time to complete the target test task for the target test task, that is, the five perception dimensions of the evaluation user of the vehicle to be evaluated, namely, the five perception dimensions of touch, hearing, smell, vision and comprehensive perception of the vehicle to be evaluated.

[0061] Furthermore, if Figure 2 As shown, after obtaining the perception results of the evaluation user on the vehicle to be evaluated, the embodiment of the present application scores the vehicle to be evaluated according to the perception results, wherein the perception results include multiple first indicator data (i.e., first-level indicators), such as the evaluation user's tactile indicator data, auditory indicator data, olfactory indicator data, visual indicator data and comprehensive perception indicator data, and multiple second indicator data (i.e., second-level indicators) in each first indicator data. For example, the tactile indicator data may include aspects such as the smooth speed of the car computer, convenient and easy-to-use buttons, and good scene experience; the auditory indicator data may include aspects such as the audio function and the prompt sound quality; the olfactory indicator data may include aspects such as the smell of the vehicle to be evaluated (i.e., the cabin) and the atmosphere inside the vehicle to be evaluated; the visual indicator data may include aspects such as the beautiful screen interface and the comfortable display color; the comprehensive perception indicator data may include aspects such as the ease of use of the car computer functions and services, and the powerful functions of the car computer.

[0062] Furthermore, the embodiments of the present application adopt a 10-point system for scoring, that is, a scoring rule of 1 to 10 points is used, and the evaluation score should be accurate to 0.5 points.

[0063] Specifically, if Figure 3 As shown, the embodiment of the present application obtains the scoring result of the first indicator data corresponding to each second indicator data based on the product of each second indicator data and the weight coefficient of each second indicator data, so as to obtain the scoring result of the vehicle to be tested based on the scoring result of the first indicator data. That is to say, the first indicator data of the embodiment of the present application is calculated based on the product of each second indicator data and the weight coefficient of each second indicator data.

[0064] The scoring result of the vehicle to be evaluated is calculated as follows:

[0065]

[0066] Among them, S is the total score of the smart cockpit, i is the first-level indicator number, S i is the score of the i-th first-level indicator, b i is the weight of the i-th first-level indicator.

[0067] The calculation method of the first indicator data score result of the vehicle to be evaluated is as follows:

[0068]

[0069] Among them, S i is the score of the i-th first-level indicator, i is the first-level indicator number, j is the second-level indicator number, n i is the number of secondary indicators contained in the i-th primary indicator, S ij is the score of the jth secondary indicator, b ij is the weight of the j-th secondary indicator.

[0124] Optionally, the embodiments of the present application may also perform blank scoring, that is, if the evaluation items are unclear or not understood, or the evaluation conditions (rainy days, configuration, insufficient time, vehicle status not met, etc.) do not meet the requirements for a meaningful evaluation, then the evaluating user may not make a score, and the evaluating user's scoring result is represented by “ / ”, which can be accurate to up to 1 decimal place, thereby calculating the evaluating user's overall subjective evaluation result.

[0125] In step S103, the eye tracking information of the evaluation user on the vehicle to be evaluated is obtained, so as to obtain an objective evaluation result of the vehicle to be evaluated based on the eye tracking information, and to obtain a comprehensive evaluation result of the vehicle to be evaluated based on the subjective evaluation result and the objective evaluation result.

[0126] According to one embodiment of the present application, eye tracking information of an evaluation user on a vehicle to be evaluated is obtained to obtain an objective evaluation result of the vehicle to be evaluated based on the eye tracking information, including: obtaining the number of glances, glance time, fixation time, and saccade data of the evaluation user on the layout information of the vehicle to be evaluated; obtaining the target interest area of ​​the evaluation user on the vehicle to be evaluated based on the glance number, glance time, fixation time, and saccade data; and obtaining the objective evaluation result of the vehicle to be evaluated based on the target interest area.

[0127] Specifically, the embodiment of the present application also needs to collect the objective evaluation results of the evaluation users on the vehicle to be evaluated, so as to obtain the evaluation users' experience feelings of the vehicle to be evaluated from an objective aspect.

[0128] Specifically, the embodiment of the present application also needs to carry out relevant preparations before conducting an objective evaluation. First, prepare an evaluation device, such as an eye movement device, to ensure the power of the evaluation device, connect it to a computer or other device, and download and install the corresponding software program; second, before using the evaluation device, the user needs to calibrate, which usually includes staring at a series of target points on the screen, such as a dashboard, a central control screen, etc., so that the system can accurately track the eye movements of the evaluation user to obtain the eye tracking information of the evaluation user for the vehicle to be evaluated; third, after calibrating the evaluation device, the evaluation is carried out, so that the evaluation user can watch the image, video or text on the screen, and the eye movement trajectory of the evaluation user is recorded through the software program, mainly obtaining the number of glances, glance time, fixation time and saccade data of the evaluation user for the layout information of the vehicle to be evaluated, and obtaining the eye movement trajectory of the evaluation user for the vehicle to be evaluated based on the number of glances, glance time, fixation time and saccade data, and performing statistical analysis on the eye movement trajectory of the evaluation user to understand the attention, interest or cognitive process of the evaluation user to different visual stimuli, thereby obtaining the target interest area of ​​the evaluation user.

[0129] Therefore, based on the specific description of the experience evaluation method of the above-mentioned vehicle, the embodiment of the present application is centered on the evaluation user, and conducts subjective and objective evaluations of the vehicle to be evaluated through the five senses of the evaluation user, including subjective feelings such as the smooth speed of the vehicle-machine, human-computer interaction, visual quality, sound effects, and cabin smell of the vehicle to be evaluated. The evaluation method also includes an eye tracking device to objectively evaluate the user's interest areas in the instrument panel and central control, so as to form a comprehensive evaluation result of the vehicle to be evaluated based on the subjective and objective evaluations of the evaluation users, and obtain a complete evaluation system for the vehicle to be evaluated by the evaluation user.

[0130] According to the vehicle experience evaluation method of the embodiment of the present application, the target test scene and evaluation user of the vehicle to be evaluated are determined, the evaluation user's perception results of the vehicle to be evaluated are obtained based on the target test scene, and the vehicle to be evaluated is scored to obtain the subjective evaluation results of the vehicle to be evaluated, and the evaluation user's eye tracking information of the vehicle to be evaluated is obtained to obtain the objective evaluation results of the vehicle to be evaluated, and the comprehensive evaluation results of the vehicle to be evaluated are obtained based on the subjective evaluation results and the objective evaluation results. Thus, the problem that the experience evaluation method in the related technology cannot form a complete evaluation system and thus cannot accurately evaluate the user's real feelings is solved, and the subjective evaluation of the vehicle is formed through the user's five senses and the user's objective evaluation of the vehicle is formed through the user's eye tracking information of the vehicle, thereby obtaining the user's comprehensive evaluation of the vehicle experience evaluation.

[0137] According to one embodiment of the present application, the scoring module 200 is specifically used for:

[0142] According to one embodiment of the present application, the scoring module 200 is specifically used for:

[0143] The scoring result of the first indicator data corresponding to each second indicator data is obtained based on the product of each second indicator data and the weight coefficient of each second indicator data, so as to obtain the scoring result of the vehicle to be evaluated based on the scoring result of the first indicator data.

[0144] According to an embodiment of the present application, the acquisition module 100 is specifically used for:

[0145] Obtain the number of glances, glance duration, fixation duration, and eye-saccade data of the evaluation user on the layout information of the vehicle to be evaluated;

[0146] Based on the number of glances, glance duration, fixation duration and eye saccade data, the target interest area of ​​the evaluated user on the vehicle to be evaluated is obtained;

[0147] Obtain objective evaluation results of the vehicle to be evaluated based on the target area of ​​interest.

[0148] According to the vehicle experience evaluation device of the embodiment of the present application, the target test scene and evaluation user of the vehicle to be evaluated are determined, the evaluation user's perception result of the vehicle to be evaluated is obtained based on the target test scene, and the vehicle to be evaluated is scored to obtain the subjective evaluation result of the vehicle to be evaluated, and the evaluation user's eye tracking information of the vehicle to be evaluated is obtained to obtain the objective evaluation result of the vehicle to be evaluated, and the comprehensive evaluation result of the vehicle to be evaluated is obtained based on the subjective evaluation result and the objective evaluation result. Thus, the problem that the experience evaluation method in the related technology cannot form a complete evaluation system and thus cannot accurately evaluate the user's real feelings is solved, and the subjective evaluation of the vehicle is formed through the user's five senses and the user's eye tracking information of the vehicle is formed to form the user's objective evaluation of the vehicle, thereby obtaining the user's comprehensive evaluation of the vehicle experience evaluation.
