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...
When a wheel slip occurs on a certain axle or when re-adhesion control is executed, the tractive effort of the wheel-slip axle changes, which causes pitching of the bogie and the carbody. As a result, weight on other axles changes, which may induce wheel slip. This paper explains the development of a control system designed to reduce wheel slip induced by axle-weight changes caused by other wheel...
