Title:
電気車の再粘着制御装置
Document Type and Number:
Japanese Patent JP6841670
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a re-adhesion control apparatus for an electric motor vehicle which is so configured that a re-adhesion torque coefficient and a holding torque coefficient can be suitably set without trial-and-error adjustment when such a control as to return an adhesive state from an idling slide state is performed by squeezing a torque transmitted to a driving wheel of an electric motor vehicle upon idling slide of the driving wheel.SOLUTION: A re-adhesion control apparatus for an electric motor vehicle having a re-adhesion controller 31 which commands for changing a transmission torque to a driving wheel 6 and detects idling slide of the driving wheel, in which a re-adhesion torque is made by multiplying a re-adhesion torque coefficient to a torque at the time of idling slide and a holding torque is made by multiplying a holding torque coefficient to said torque. The re-adhesion controller performs such a re-adhesion operation as to command for changing to the re-adhesion torque during only a first holding time, and to command for changing to the holding torque during only a second holding time. The controller measures a re-adhesion time until the driving wheel returns to an adhesive state from an idling slide state, and corrects the re-adhesion torque coefficient so that a value when this re-adhesion time is measured plural times becomes equal to the first holding time.SELECTED DRAWING: Figure 3
