[0056] Figure 1 Schematic flow chart showing a method for detecting a driving behavior that causes excessive wear of a clutch of a vehicle according to the present invention.

[0057] In the first method step 101, engine speed information, wheel speed information, and clutch pedal information are acquired.

[0058] Herein, optionally, the engine speed information, the wheel speed information, and the clutch pedal information are acquired by means of sensors, wherein, for example, the engine speed information and the wheel speed information are acquired by means of a speed sensor, and the clutch pedal information is acquired by means of a position sensor, for example.

[0059] In the second method step 102, an actual transmission ratio of a powertrain of the vehicle is calculated based on the engine speed information and the wheel speed information.

[0060] Herein, optionally, a quotient of the engine speed obtained from the engine speed information and the wheel speed obtained from the wheel speed information is calculated as the actual transmission ratio of the vehicle's transmission system.

[0061] In the third method step 103, a reference transmission ratio is calculated based on the engine speed information and the clutch pedal information.

[0062] Herein, the reference transmission ratio corresponds to the transmission ratio of the vehicle's transmission system under ideal conditions, especially in the case of no clutch wear.

[0063] In the fourth method step 104, it is inferred that there is a driving behavior that causes excessive wear of the clutch of the vehicle when the actual transmission ratio deviates from the reference transmission ratio by more than a predetermined degree.

[0064] Herein, the predetermined degree can be set or changed as needed. Optionally, for example, it is inferred that there is a driving behavior that causes excessive wear of the clutch of the vehicle when the actual transmission ratio deviates from the reference transmission ratio by more than 10%, preferably more than 5%.

[0065] Here, it is also possible to calculate the rate of change of the throttle opening, and additionally infer the existence of a driving behavior that causes excessive wear of the clutch of the vehicle when the rate of change of the throttle opening is greater than or equal to a rate-of-change threshold. That is to say, in the fourth method step 104, it is inferred whether there is a driving behavior that causes excessive wear of the clutch of the vehicle while considering both the deviation between the actual transmission ratio and the reference transmission ratio and the rate of change of the throttle opening.

[0066] Here, in particular, the above-described method for detecting a driving behavior that causes excessive wear of the clutch is not implemented when the engine speed obtained from the engine speed information is equal to 0. That is to say, the above-described method for detecting a driving behavior that causes excessive wear of the clutch is only implemented when the engine is running.

[0067] Here, in particular, when the wheel speed obtained based on the wheel speed information is greater than a predetermined first wheel speed threshold or the vehicle speed obtained based on the wheel speed information is greater than a predetermined first vehicle speed threshold, the above-described method for detecting a driving behavior that causes excessive wear of the clutch is not implemented. That is to say, the above-described method for detecting a driving behavior that causes excessive wear of the clutch is only implemented when the vehicle is traveling at a low speed, especially during the vehicle start-up phase. Here, the first wheel speed threshold and / or the first vehicle speed threshold can be set or changed as needed.

[0068] Here, information is output when it is inferred that there is a driving behavior that causes excessive wear of the clutch of the vehicle. The information can, for example, trigger an auditory signal and / or a visual signal and / or a tactile signal, thereby prompting the driver to improve his driving behavior.

[0069] Figure 2 A schematic flowchart showing a method for detecting an excessive wear state of a clutch of a vehicle according to a first embodiment of the present invention is shown.

[0070] In a first method step 201, in particular, by means of the method described above with the aid of Figure 1 the driving behavior that causes excessive wear of the clutch of the vehicle is detected.

[0071] In a second method step 202, based on the cumulative number of times of detecting a driving behavior that causes excessive wear of the clutch of the vehicle or the cumulative duration of detecting a driving behavior that causes excessive wear of the clutch of the vehicle, the excessive wear state of the clutch of the vehicle is inferred.

[0072] Here, the greater the cumulative number of driving behaviors detected that cause excessive wear of the vehicle's clutch or the longer the cumulative duration of the driving behaviors detected that cause excessive wear of the vehicle's clutch, the more severe the excessive wear state of the vehicle's clutch is indicated.

[0073] Here, for example, the excessive wear state obtained by means of the method for detecting the excessive wear state of the vehicle's clutch according to the first embodiment of the present invention is prompted to the driver in the form of an auditory signal and / or a visual signal.

[0074] Figure 3 A schematic flowchart showing a method for detecting the excessive wear state of the vehicle's clutch according to the second embodiment of the present invention is shown.

[0075] In the first method step 301, engine speed information, wheel speed information, and clutch pedal information are acquired.

[0076] Here, optionally, the engine speed information, wheel speed information, and clutch pedal information are acquired by means of sensors, wherein, for example, the engine speed information and wheel speed information are acquired by means of a speed sensor, and the clutch pedal information is acquired by means of a position sensor, for example.

[0077] In the second method step 302, the actual transmission ratio of the vehicle's powertrain is calculated based on the engine speed information and the wheel speed information.

[0078] In the third method step 303, the continuous change of the actual transmission ratio is monitored.

[0079] In the fourth method step 304, in the case where the duration of the continuous change is greater than or equal to a predetermined time threshold and / or the amplitude of the continuous change is greater than or equal to a predetermined amplitude threshold, the excessive wear state of the vehicle's clutch is inferred.

[0080] Here, in particular, the method for detecting the excessive wear state of the vehicle's clutch according to the second embodiment of the present invention is not implemented when the wheel speed obtained based on the wheel speed information is less than a predetermined second wheel speed threshold or the vehicle speed obtained based on the wheel speed information is less than a predetermined second vehicle speed threshold. That is to say, the above-mentioned method for detecting the excessive wear state of the vehicle's clutch is implemented only when the vehicle is traveling at a high speed, especially when the vehicle is accelerating. Here, the time threshold and / or the amplitude threshold can be set or changed as needed. Here, the second wheel speed threshold and / or the second vehicle speed threshold can be set or changed as needed.

[0081] Here, for example, the driver is prompted in the form of an auditory signal and / or a visual signal with the excessive wear state obtained by means of the method for detecting the excessive wear state of the clutch of a vehicle according to the second embodiment of the present invention.
