Problems solved by technology

[0002] Especially for vehicles equipped with manual transmissions, the driver's improper driving behavior, especially improper operation of the clutch, is likely to cause excessive wear of the clutch, thereby impairing vehicle performance and even causing danger
However, in the daily driving process, it is difficult for the driver to realize such improper driving behavior in time and make improvements.
In addition, it is difficult for the driver to recognize excessive clutch wear in time, unless this has seriously affected vehicle performance, such as difficulty in starting the vehicle

Embodiment Construction

[0056] figure 1 A schematic flow chart of a method according to the invention for detecting driving behavior leading to excessive wear of a clutch of a vehicle is shown.

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

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

[0059] In a 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] Here, optionally, the quotient of the engine speed obtained from the engine speed information and the wheel speed obtained from the whe...

Abstract

The present invention relates to a method for detecting a driving behavior causing excessive wear of a clutch of a vehicle. The method comprises the following steps: acquiring engine speed information, wheel speed information, and clutch pedal information; calculating an actual transmission ratio of a power system of the vehicle based on the engine rotating speed information and the wheel rotating speed information; calculating a reference transmission ratio based on the engine speed information and the clutch pedal information; and in the event that the actual gear ratio deviates from the reference gear ratio by more than a predetermined degree, concluding that there is a driving behaviour causing excessive wear of a clutch of the vehicle. The invention also relates to a device for detecting the driving behavior causing excessive wear of the clutch of the vehicle. The invention also relates to a method and a device for detecting the excessive wear state of the clutch of the vehicle. The invention also relates to the vehicle and a computer readable storage medium.

Description

technical field [0001] The present invention relates to a method and a device for detecting driving behavior leading to excessive wear of a clutch of a vehicle. The present invention also relates to a method and apparatus for detecting an excessive wear condition of a clutch of a vehicle. The invention also relates to a vehicle comprising a device according to the invention for detecting a driving behavior leading to excessive wear of a clutch of the vehicle and / or a device according to the invention for detecting a state of excessive wear of a clutch of a vehicle. The invention also relates to a computer-readable storage medium. Background technique [0002] Especially for a vehicle equipped with a manual transmission, the driver's improper driving behavior, especially improper operation of the clutch, is likely to cause excessive wear of the clutch, thereby impairing the performance of the vehicle and even causing danger. However, it is difficult for the driver to realiz...
