- Step S7 includes a driver classification. On the basis of the driving profile that was determined in step S2, the driver is classified with regard to himself
- Driving style takes place, for example, by a key figure that is determined from the driving profile.
- classes are provided, for example, into which the respective driver can be classified, for example with regard to consumption or wear-optimal or with regard to leisure or critical driving style.
- Each corresponds determined key figure of a certain class.
- the driving style is preferably derived from the driving profile and / or the movement variables.
- the code can also be made available to other users so that they can decide, for example, whether they want to book a trip with this driver.
- FIG. 3 shows a further development of the method from FIG. 1.
- steps S1 and S2 which essentially correspond to those from FIG. 1, further steps have been added here. Therefore, these steps are mainly discussed below.
- a step S4 is shown in which at least one operating variable n, M is detected. If appropriate access is possible, it can be, for example, a speed n, a torque M or an engine load. Such variables can, for example, via a corresponding interface in the vehicle,
- CAN or OBD interface can be made accessible via a CAN or OBD interface.
- these can be variables that describe the operation of elements of the drive train of the vehicle.
- This can be the speed n and torque M of an engine, a transmission, a differential or other elements of the vehicle.
- a further step S5 is also provided, in which at least one additional item of information is recorded which is suitable for evaluating a driver's driving behavior.
- an assessment of the driving style can be carried out on the basis of this steering angle.
- step S6 the driving profile that was created in step S2 is supplemented by the at least one recorded operating variable n, M that was recorded in step S4, or by the at least one additional item of information that was recorded in step S5.
- the driving profile which for example has a time curve of the speed v or the acceleration a, can be expanded to include further information.
- step S6 is followed by a further step S3, in which a determination of a
- Vehicle loading takes place from the driving profile.
- the driving profile is evaluated in order to to determine how high the vehicle load has been so far.
- a maintenance requirement for the vehicle can, for example, be derived from the determined vehicle load.
- the method is designed, in particular, to recommend maintenance at an earlier point in time for a driving style that has relatively high accelerations or speeds than for a driving style that has comparatively low accelerations and speeds.
- an assessment of a driver can be derived from the driving profile. This can be done, for example, by step S7 from FIG. 2.
- the driver can, for example, be classified as a fuel-efficient driver type or as a fuel-efficient driver
- Driver type are classified. This can, for example, be based on the
- Acceleration behavior of the driver take place. If, for example, high deflections are recorded in the course of a longitudinal acceleration, it can be concluded that the driving style is hectic or fuel-efficient. Alternatively or additionally, for example, an average acceleration in the direction of travel can be determined.
- Vehicle brakes are hit. If, for example, high longitudinal decelerations are to be recorded in the course of a longitudinal acceleration which, for example, are above a predetermined value which corresponds, for example, to a more favorable deceleration, then it can be concluded that the mode of driving is unfavorable to wear. Alternatively or additionally, for example, an average deceleration in the direction of travel can be determined. If this exceeds a certain limit value, it can also be concluded that the brake wear is higher.
- the decision as to whether maintenance is to be carried out is made in particular on the basis of information that includes the vehicle type, for example.
- FIGS. 1 to 3 can be combined with one another as desired.
- individual process steps can be exchanged for one another.
- step S7 in FIG. 2 can be swapped for step S3 in FIG. 3 become.
- Individual process steps can also be omitted.
- steps S3, S4, S5, S6 or S7 can be omitted. It is also understood that the sequence of the method steps can be varied as desired, with individual steps also being able to be carried out several times.
- FIG. 4 shows a configuration for carrying out the method according to the invention.
- a vehicle 1 is shown in plan view.
- a device 2 is provided which is designed to carry out at least part of the method according to the invention.
- the device 2 is designed, for example, as a mobile terminal device, that is to say, for example, as a smartphone or tablet.
- the device 2 is designed to
- the device 2 is fixed in the vehicle 1 so that it cannot perform any relative movement, for example due to a dynamic driving style, with respect to the vehicle 1.
- the detected movement variables x, v, a x and a y can thus be understood to a good approximation as the movement variables of the vehicle 1.
- a driving profile can thus be created from the recorded movement variables x, v, a x and a y .
- Longitudinal acceleration a x and transverse acceleration a y are combined, for example, as a two-dimensional vector of acceleration a.
- the device 2 is via a data connection 4, for example via a

- the EDP system 3 is essentially designed to receive information from the device 2 via the
- Data connection 4 can be sent, store and manage.
- information from further devices 2 can also be stored and managed in the EDP system 3.
- the device 2 and the EDP system 3 are designed to at least partially carry out the method according to the invention.
- the movement variables x, v, a x and a y are recorded in the
- the further method steps which essentially only deal with processing and evaluating the recorded variables, can be carried out in the device 2 or in the EDP system 3.
- Some of these steps can also be carried out in the device 2, with the determined driving profile then being transmitted via the data connection 4 to the EDP system 3, which from the driving profile in turn determines a vehicle load according to step S3 from FIG. 3 or carries out a driver classification according to step S7 from FIG. 2.
- a user 8 who is connected to the EDP system 3 via a data connection 7, for example via a cellular network.
- the user can also receive data or information from the EDP system.
- the user 8 has, for example, a suitably designed interface, for example an app on a smartphone, so that he can call up the information as comfortably as possible. If the user 8 is a passenger, he can use this to call up a driver classification and thus decide whether he would like to book a trip with the corresponding driver. If the user 8 is a superior of the driver, he can decide on the basis of the classification to train the driver in order to make him more attractive to other passengers.
- FIG. 5 shows a further development of the configuration from FIG. 4.
