Simulation of a vehicle in longitudinal motion with clutch engagement and release
A simple model for driver and vehicle in longitudinal motion is
developed and simulated. The focus is on describing and handling
simulation of clutch lock and clutch release which changes the model
structure, both during start and gear shifts, in Simulink. Special
attention is given the problem of simulating start and stop of a
vehicle with rolling resistance at zero speed. Only principles for
simulating the system with variable structure is of interest and
therefore the models are maintained at lowest possible complexity. The
system is successfully simulated and the validation is performed using
three scenarios: one with only clutch lock and clutch release, one
with start and stop of vehicle, and one full European drive-cycle.
