Description

This invention relates to the field of data processing, more particularly it relates to a method, system and corresponding apparatus for providing data for comparing vehicle categories.

Before buying a new vehicle, people usually sift through vehicle and feature ratings published by test facilities, satisfaction survey agencies, consulting institutes, or self-media platforms in order to use the rating results to choose the vehicle best suited to their needs and needs select the most suitable equipment and then make the purchase.

However, on the one hand, these vehicle evaluation facilities buy real vehicles to test them, for example, on the test bench or in a closed proving ground, etc., and on the other hand, conduct surveys among customers to obtain evaluation results on specific vehicles. This procedure is very labor- and material-intensive, and the usability of the assessment results is by no means guaranteed, which is particularly due to the fact that after an upgrade or a change in the vehicle system, the previous assessment results are no longer applicable and the assessment results are also subject to the subjective opinion of the assessor subject and are therefore not sufficiently objective.

The aim of this invention is to provide an improved method for providing data for comparing vehicle categories, an improved system for carrying out said method, an improved client-side device, an improved server device, an improved vehicle-side terminal device and a corresponding computer program product to solve at least part of the problems existing according to the current state of the art.

  5. e) Wirtschaftlichkeit,
  6. f) Ausfallrate.

Optionally, the identification data provided by the in-vehicle terminals 300 includes the historical identification data and/or the current identification data of these vehicles.

• S400: Analysis of the characteristics and conversion into performance data expressing the performance of these vehicles; optionally, in step S400, when the characteristic data is analyzed and converted into performance data, at least one of the following elements a) to f) is taken into account:

[Anzahl dieser Fahrzeugmodelle mit aktivierter Funktion / Gesamtanzahl antwortender Fahrzeuge dieses Modells]
wobei gilt: A_n = momentane Gebrauchstauglichkeit einer Funktion von Modell N; Feststellung des Fahrzeugmodells N = Entschlüsselung des VIN-Codes; Feststellung, dass die Funktion aktiviert ist = Daten zum aktuellen Funktionsstatus;As an exemplary embodiment, in step S400 a) Usability of a function is considered, where the usability of a function represents the most intuitive way to assess consumer confidence in the vehicle function and at the same time can reflect how well the function is designed and calibrated for this vehicle model . For example, the serviceability of a function can be calculated using the following formula:

[Number of these vehicle models with the function activated / total number of responding vehicles of this model]
where: A _n = current fitness for purpose of a function of model N; vehicle model identification N = VIN code decoding; determining that the feature is enabled = current feature status data;

By determining the ratio, in relation to this vehicle model, of the number of vehicles that currently have the function activated to the total number of vehicles in operation, the serviceability A of a function can be calculated, where the higher the value A, the higher the usability of the function. Here, it is understood that, considering the different needs of the corresponding consumer target groups and application scenarios of the different vehicle categories, in order to give the assessment results for the choice and purchase of a vehicle by consumers more meaningful, the usability of a function depending on the market segment are weighted accordingly can. For example: As far as the lane assistant (LKA) is concerned, different A value classifications apply to vans and small cars.

As an exemplary embodiment, in step S400 b) mileage is taken into account, with mileage being the aspect most frequently mentioned by consumers. As a rule, mileage is already involved in the phase of registering a vehicle model, with specific assessment items of mileage also being the trigger Condition can act, for example, triggering the vehicle-side terminal 300 to collect identification data, and / or triggering the vehicle-side terminal 300 to send the identification data to the server 200, with the result that the databases of the in-vehicle terminals 300 and / or the server 200 have characteristics that are more based on everyday driving environments and are not proving ground characteristics.

For example, the mileage relates to the starting acceleration, for example, when it is detected as a trigger that the preceding vehicle starts with an acceleration ≥Q m/s ² from a standstill, the dynamic curve of the ego vehicle of the acceleration from a standstill is recorded , and at the same time the detection result of the facial expression is also recorded in the data for detecting the condition of the driver of this vehicle, because if it is detected, for example, that the facial expression differs from the normal expression (e.g.: worried), then there is a clear difference in this case the characteristic data when the normal facial expression is detected, and these two also have very different influences on the assessment of the driving performance when analyzed and converted into performance data indicating the performance of the vehicles.

For example, mileage relates to braking performance, by retrieving the accumulated historical characteristics, filtering out the data on the light/deep application of the brake pedal by the driver and processing the time-velocity curve to determine the reaction time of the vehicle to achieve a braking effect. At the same time, the detection result of the facial expression is also recorded in the data for detecting the condition of the driver of this vehicle, because, for example, if it is detected that the facial expression is different from the normal expression (e.g.: worried), then there is a clear difference from the identification data in this case when normal facial expressions are detected, these two also have very different influences on the assessment of driving performance when analyzed and converted into performance data indicating the performance of the vehicles.

For example, driving performance refers to steering behavior, whereby by retrieving the cumulative historical characteristics, filtering out the steering data and processing the data on the steering wheel angle and the actual vehicle angle (heading angle, side slip angle), the deviation between the steering effect achieved on the vehicle and the operation by the driver driver and also calculates the smoothness with which the driver achieves the steering angle.

As an embodiment, in step S400 c) safety performance is taken into account, there is a close relationship between safety performance and the lives of vehicle occupants, and with the development of vehicle electronics, consumers have also developed a safety consciousness, in which passive safety is the basis and active safety form the main concern.

For example, the recordings of the driver's visual body movements can be used to assess the safety performance, for example, based on the total eye movements (direction of gaze) and body movements (forward, sideways inclination), an assessment is made as to whether a visual body movement is present, with a large number of per 100 km occurring sight-related body movements, it can therefore be judged that the visibility conditions with this vehicle model are not particularly good. In addition, within the 5s before and after the function is triggered, the recognition result of the facial expression is also recorded in the data for detecting the state of the driver of this vehicle, for example, if the facial expression is recognized as different from the normal expression (e.g.: worried), then in this case there is a clear difference from the characteristic data when normal facial expressions are detected, and these two also have very different influences on the assessment of driving performance when analyzed and converted into performance data to indicate the performance of the vehicles.

As an exemplary embodiment, comfort is taken into account in step S400 d), with the assessment of comfort essentially relating to aspects such as NVH, seats, air conditioning and smell, with the quality of the air in the vehicle (in particular the comparison of the air inside and outside of the vehicle), the vibration of the body, the performance of the air conditioning system (especially the comparison between the set and the actual temperature) can all be recorded cumulatively to serve as a basis for the conversion into performance data in step S400.

As an exemplary embodiment, in step S400 e) economic efficiency is taken into account, economic efficiency being in particular the two aspects of vehicle usage costs and fuel (electricity) consumption, which have a major influence on the selection of the vehicle and the consumer's purchase decision . By processing the cumulatively recorded historical key data, for example extracting mileage and fuel (electricity) consumption within an ignition cycle, calculating fuel (electricity) consumption or even directly recording the current fuel (electricity) consumption, thanks to large Amounts of data on fuel (electricity) consumption under operating conditions in China can be determined relatively objectively, with the lower the fuel (electricity) consumption, the greater the satisfaction of consumers.

As an exemplary embodiment, in step S400 f) the failure rate is taken into account, with the failure rate of this vehicle being able to be classified on the basis of the recorded cumulative number of failures and the mileage and the age of the vehicle.
