An arrangement for and a method of monitoring the state of wear of a motor vehicle friction clutch |
摘要 |
An arrangement for monitoring the wear status of a friction clutch in the drivetrain of a motor vehicle driven by an internal combustion engine includes a wear detection circuit that responds to speed information representing the instantaneous input speed of the friction clutch supplied by a first speed sensor and to information supplied by a movement sensor representing the beginning of a starting process. The wear detection circuit supplies, as a measurement for the loading of the friction clutch during a starting process, load information which is a predetermined monotonic function of a value of the first speed information following the beginning of movement after a predetermined time interval. The monotonic function could also be of a mean value from a plurality of values of the first speed information succeeding one another at predetermined time intervals following the beginning of movement. |
