Title:
CONTROLLER AND CONTROL METHOD FOR VEHICLE MOTOR
Document Type and Number:
Japanese Patent JP3152785
Kind Code:
B2
Abstract:
PURPOSE: To allow highly accurate control of controllers for controlling individual vehicle motors while preventing adverse effect of idling of one motor onto other motors.
CONSTITUTION: A preceding truck has first and second shafts whereas a following truck has third and fourth shafts. Upon receiving a command from a main controller 12, a general controller 13 controls individual controllers 14a-14d for motors 15a-15d first to fourth shafts to generate hauling forces for equalizing the adhesion coefficients at the time of powering. Upon occurrence of idling on first or third shaft at that time, current is constricted to lower the hauling force of the second or fourth shaft. On the contrary, upon occurrence of idling on the second or fourth shaft, other shafts are left as they are. Furthermore, when idling occurs on other shaft even after this processing, current is constricted while keeping proportionality in the axle loads for all shafts and current is recovered upon readhesion.
