Abstract
Simulation plays an important role in optimising the performances of the drive line of the off-road vehicles. The models of the engine, torque converter, transmission and running gear are assembled into a large model used for estimation of the vehicle acceleration performances. The paper presents a proposal for modelling of the torque converter dimensionless characteristics using segmented continuous function taking as variable the inverse of the kinematic ratio. There are analysed the variants of the characteristics offered by the literature as well as the implementation of the torque converter model into the vehicle model.
