PROBLEM TO BE SOLVED: To
accurately estimate an adhesion
coefficient between a wheel and a rail
during the detection of slip and skid by
continuing to give commands for current
command value corresponding to an
estimated value of the tangential force
estimated by a tangential force estimating
method and thereafter by increasing the
current command value toward the
current command value corresponding to
a preset performance of the electric car.
SOLUTION: A current command
generating section 4 continues to give a
current command value to a tangential
force estimating section 6, a re- adhesion
detecting section 9 receives an axial
acceleration from an axial acceleration
arithmetic section 19 and outputs a re-
adhesion detecting signal to a current
command value target-setting section 8
on the condition that a slip and skid-
detecting signal and an axial acceleration
zero detection signal have been output.
The current command value target setting
