Abstract
(DE)
Ein Solldrehmoment (TQ_REQ) wird aus einem Drehmomentfaktor (TQ_SCA_FAC), einem maximalen Drehmoment (TQ_MAX) und einem minimalen Drehmoment (TQ_MIN) ermittelt. Der Drehmomentfaktor (TQ_SCA_FAC) wird aus einem Pedalwert (PVS) und der Drehzahl (N) abgeleitet. Das maximale und das minimale Drehmoment (TQ_MIN, TQ_MAX) werden in Abhängigkeit von der Drehzahl (N), einem Verlustdrehmoment (TQ_LOSS) und den Betriebsgrößen ermittelt. Das Verlustdrehmoment (TQ_LOSS) wird in Abhängigkeit von der Drehzahl (N) und den Betriebsgrößen ermittelt.
(EN)
A set torque (TQ_REQ) is determined from a torque factor (TQ_SCA_FAC), a maximum torque (TQ_MAX) and a minimum torque (TQ_MIN). The torque factor (TQ_SCA_FAC) is derived from a pedal value (PVS) and the speed (N). The maximum and the minimum torque (TQ_MIN, TQ_MAX) are determined in relation to the speed (N), the loss torque (TQ_LOSS) and the performance parameters. The loss torque (TQ_LOSS) is determined in relation to the speed (N) and the performance parameters.
(FR)
Un couple de rotation de consigne (TQ_REQ) est calculé à partir d'un facteur de couple (TQ_SCA_FAC), d'un couple maximum (TQ_MAX) et d'un couple minimum (TQ_MIN). Le facteur de couple est dérivé d'une valeur donnée par la pédale (PVS) et du nombre de tours (N). Le couple maximum et le couple minimum (TQ_MAX, TQ_MIN) sont calculés en fonction du nombre de tours (N), d'un couple de perte (TQ_LOSS) et des paramètres de fonctionnement. Le couple de perte (TQ_LOSS) est calculé en fonction du nombre de tours (N) et des paramètres de fonctionnement.
