Abstract
A method for opening of an automatically controlled clutch (106) of a vehicle which comprises a combustion engine (101) for generating driving force intended for transmission to at least one powered wheel (113, 114) via the clutch and a gearbox (103). The method includes opening the clutch at an initial rate to at least a first position substantially corresponding to a position at which the clutch can at most transmit the maximum torque which the combustion engine can deliver at idling speed, and from the first position, opening the clutch at a second rate which is lower than the initial rate.
Claims15
A method for opening of an automatically controlled clutch of a vehicle wherein the vehicle comprises a combustion engine for generating driving force intended for transmission to at least one powered wheel via the clutch and a gearbox, the method comprising the steps of:
- opening the clutch at an initial rate of opening to at least a first clutch position substantially corresponding to a position at which the clutch can at most transmit a maximum torque which the combustion engine can deliver at idling speed;
- and
- from the first position, opening the clutch at a second rate of opening which is lower than the initial rate.
A computer program product comprising a non-transitory computer-readable medium and a computer program, the computer program containing executable program code, the computer program, when the executable program code is executed in a computer, causing the computer to carry out a method for opening of an automatically controlled clutch of a vehicle wherein the vehicle comprises a combustion engine for generating driving force intended for transmission to at least one powered wheel via the clutch and a gearbox, the method comprising the steps of:
- opening the clutch at an initial rate of opening to at least a first clutch position substantially corresponding to a position at which the clutch can at most transmit a maximum torque which the combustion engine can deliver at idling speed;
- and
- from the first position, opening the clutch at a second rate of opening which is lower than the initial rate;
- wherein the computer program is contained in the non-transitory computer-readable medium.
A system for opening of an automatically controlled clutch of a vehicle, wherein the vehicle comprises a combustion engine for generating driving force for transmission to at least one powered wheel via the clutch and a gearbox and other devices configured and operable for:
- opening the clutch at an initial rate to at least a first position substantially corresponding to a position at which the clutch can at most transmit the maximum torque which the combustion engine can deliver at idling speed;
- and
- from the first position, opening the clutch at a second rate which is lower than the initial rate.
A vehicle comprising a system for opening of an automatically controlled clutch of a vehicle wherein the vehicle comprises a combustion engine for generating driving force for transmission to at least one powered wheel via the clutch and a gearbox and other devices configured and operable for:
- opening the clutch at an initial rate to at least a first position substantially corresponding to a position at which the clutch can at most transmit the maximum torque which the combustion engine can deliver at idling speed;
- and
- from the first position, opening the clutch at a second rate which is lower than the initial rate.
