Abstract

A diagnostic method for vehicles from a group of vehicles wherein data relating to at least one vehicle from the group of vehicles are acquired from a social medium. Complaints relating to a criticized characteristic of the at least one vehicle are determined depending on the acquired data. Diagnostic information is generated for at least one vehicle depending on the complaints.

Claims

1. A server-based diagnostic method for vehicles of a group of vehicles, the diagnostic method comprising:

acquiring data relating to at least one vehicle from the group of vehicles, from a social medium;

automatically determining, via determination device, complaints relating to a criticized characteristic of the at least one vehicle, depending on the acquired data; and

generating diagnostic information, via a processing device, for the at least one vehicle depending on the complaints,

retrieving vehicle diagnostic information from a vehicle diagnostic system of a vehicle from the group of vehicles depending on the generated diagnostic information, and validating the diagnostic information generated based on the vehicle diagnostic information retrieved,

wherein the social medium is a blog or user forum,

determining a popularity of the use of a vehicle function from the group of vehicle functions, based on frequency of use of the vehicle function as determined by analysis of the acquired data,

automatically electronically logging, via electronic log mechanisms in a fleet of vehicles, every use of a vehicle function by users of the fleet of vehicles to determine an actual popularity of the vehicle function based on an actual frequency of use by the users, and

validating the popularity of the use of the vehicle function based on the acquired data from the social medium by comparing the determined popularity with the actual popularity.

2. The diagnostic method of claim 1, further comprising:

acquiring additional data relating to at least one vehicle from the group of vehicles from an additional social medium;

determining additional complaints relating to the criticized characteristic, depending on the acquired additional data; and

wherein

the diagnostic information generated is based on the additional complaints.

3. The diagnostic method of claim 1, further comprising:

retrieving fault complaints from repair databases of workshops relating to at least one vehicle from the group of vehicles; and

generating the diagnostic information furthermore depending on the fault complaints.

4. The diagnostic method of claim 2, further comprising:

evaluating the social media depending on the complaints determined from the data of the social media and the fault complaints from the repair databases; and

weighting the social media depending on the evaluation.

5. The diagnostic method of claim 1, wherein the data comprise a text message composed by a user of the at least one vehicle.

6. The diagnostic method of claim 1, further comprising:

determining additional information from the data of the social medium, wherein the additional information comprises at least information from a group comprising;

an age of a person who input the data into the social medium,

a driver profile of a person who input the data into the social medium,

a geographical position at which the complaint occurred or the data relating to the complaint were input into the social medium,

a time when the complaint occurred or the data relating to the complaint were input into the social medium, and

weather conditions prevailing when the complaint occurred or the data relating to the complaint were input into the social medium.

7. The diagnostic method of claim 1, wherein the group of vehicles comprises a plurality of vehicles of the same type, wherein the vehicles of the same type have at least one common characteristic from a group, comprising:

vehicle type;

engine type;

equipment characteristic; and

production period.

8. The diagnostic method claim 1, wherein the diagnostic information has at least information from a group, comprising:

a fault of a function of the vehicle;

a failure of a function of the vehicle;

a fault of a component of the vehicle;

a failure of a component of the vehicle;

a vehicle state in which the complaint was determined; and

a usage condition in which the complaint was determined.

10. The method of claim 1, wherein the diagnostic information comprises malfunction of a component of the vehicle, wherein a database stores the diagnostic information with other similar diagnostic information and the processing device determines the malfunction occurs systematically when the malfunction is diagnosed more frequently than a normally prevailing failure probability.

11. The method of claim 10, wherein the processing device determines the malfunction occurs randomly when the malfunction is diagnosed less frequently than the normally prevailing failure probability.

9. A diagnostic device, comprising:

server that acquires data relating to at least one vehicle from a group of vehicles, from a social medium;

a determination device for automatically determining complaints relating to a criticized characteristic of the at least one vehicle, based on the acquired data; and

a processing device for generating diagnostic information via a fault and cause analysis to determine a malfunction for the at least one vehicle based on the complaints determined and complaints stored in a database in communication with the processing device,

electronic log mechanisms that automatically record every use of vehicle functions by users of a fleet of vehicles and communicate the recordings data to the acquisition means,

wherein the determination device determines and validates a popularity of a use of a vehicle function from the vehicle functions, based on frequency of use of the vehicle function as determined by analysis of the acquired data and correlation to the recordings data,

wherein the social medium is a blog or a user forum.
