Anti-slip re-adhesion control method for increasing the tractive force of locomotives through the early detection of wheel slip convergence

We have developed a re-adhesion control method for increasing tractive force through early detection of wheel slip convergence, using less delayed rotational acceleration signal than the conventional one for slip detection. We focus on the effect of the restraint of tangential force change by the early slip convergence detection. Accordingly, the slip induction of other axes is restrained and increase of tractive force of locomotives is expected. Its effectiveness has been verified by simulation tests and running tests using a HD300-Type diesel hybrid shunting locomotive.
