Abstract (en)
[origin: WO2021234485A1] A method for generating a command signal (Ei) for the value of idle speed for a combustion engine of a tractor, provides receiving a transmission fluid temperature signal (To), a cooling fluid temperature signal (Tc), a tractor speed signal (Vtr) on the control unit. Furthermore, the method provides selecting a first engine idle speed value (Eic1) as a function of the cooling fluid temperature signal (Tc), a second engine idle speed value (Eiol) as a function of the transmission fluid temperature signal (To), and a third engine idle speed value (EiV1) as a function of the tractor speed signal (Vtr), if the tractor speed signal (Vtr) is not zero. Successively, the method provides calculating a desired engine idle speed value (Eid) as a function of the first (Eic1), the second (Eio1), and the third engine idle speed value (EiVl) and generating a command signal (Ei) of the engine idle speed value on the control unit as a function of the desired engine idle speed value (Eid) calculated on the processor. A control unit for a tractor comprises a processor configured to execute the steps of the method of the present invention.
