Abstract [sv]

På Volvo Cars Corporation (VCC), är vevaxelmoment styrsignal för kalibrering av växellådan under växling. Målet med detta examensarbete är att utforma en verifieringsmetod (DVM) för vevaxelns vridmoment. Baserat på hjulet vridmoment, beräknas vevaxel momentet genom att kompensera momentförluster steg för steg. De relativa vridmoment-förlusterna ges av tidigare mätningar. Momentförlusterna klassificeras enligt olika komponenter i fordonets transmissionssystem.

Vevaxelns modellerade vridmomentsignal används som referenssignal för att utvärdera prestandan hos verifieringsmetoden (Design Verification Method). Referenssignalen är certifierad inom ett visst intervall av VCC.

Abstract [en]

At Volvo Cars Corporation (VCC), crankshaft torque is a control signal for calibrating the gearbox for gear shifting operations. The goal of this master thesis is to design a verification method (DVM) for crankshaft torque. Based on the wheel torque, the crankshaft torque is calculated by compensating the torque losses step by step. The relative torque loss data are provided by the previous measurements. The torque losses are classified by different components in the vehicle transmission system.

The modeled crankshaft torque signal will be used as a reference signal to evaluate the performance of the Design Verification Method. The reference signal is certificated within a certain range by VCC.
