<p>PURPOSE:To utilize adhesion between a wheel and a rail effectively by quickly reducing driving force or braking force after a racing or a coasting is generated. CONSTITUTION:A main controller 2 controls torque generated from a main motor 3 in response to a torque command Tp. Driving-wheel peripheral velocity VM, driving-wheel peripheral acceleration DELTAVM, car velocity VT and car acceleration DELTAVT are inputted to a logical operation circuit 12, and the circuit 12 prepares a re-adhesion control signal Tf. The re-adhesion control signal TfR during a racing or a coasting acceleration period is prepared with a predetermined level on the basis of a re-adhesion control signal at the time of the detection of the racing or a coasting, a signal increasing at a fixed ratio with time after the detection of the racing or a coasting regardless of a racing or a coasting phenomenon, a signal related to the racing or a coasting phenomenon, and a signal at a fixed level, which is regardless of the racing or a coasting phenomenon and does not change with time.</p> |
