Abstract
A method for determining a need for contact point adaptation for a clutch (106) of a vehicle (100), which clutch (106) transmits driving power between a power source engine (101) and at least one powered wheel (113, 114). At a first point in time, determining a first temperature (T1) of the clutch (106), comparing the first temperature (T1) with a second temperature (T2) of said clutch (106) determined at a second point in time which precedes the first point in time, and determining a need for contact point adaptation when the first temperature (T1) differs from the second temperature (T2) by more than a first value (ΔT)).
Claims14
A method for determining a need for contact point adaptation for a clutch of a vehicle, such that said clutch is enabled to transmit driving power between a first power source comprising an engine of the vehicle and at least one powered wheel, the method comprises:
- determining a first temperature (T1) of said clutch at a first time;
- determining a second temperature (T2) of said clutch at a second time which precedes said first time;
- comparing said first temperature (T1) with said second temperature (T2);
- and
- determining said need for contact point adaptation when said first temperature (T1) differs from said second temperature (T2) by more than a first value (ΔT).
A system for determining a need for a contact point adaptation for a clutch of a vehicle, wherein said clutch is configured to transmit driving power between a first power source in the form of an engine and at least one powered wheel of said vehicle;
- the system comprising:
- a temperature sensing arrangement for determining a first temperature (T1) of said clutch at a first time;
- a comparator for comparing said first temperature (T1) with a second temperature (T2) of said clutch at a second time which precedes said first time;
- and
- a device configured for determining a need for contact point adaptation when said first temperature (T1) differs from said second temperature (T2) by more than a first value (ΔT).
