Title:
トラクション制御装置及びトラクション制御方法
Document Type and Number:
Japanese Patent JP6711485
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a traction controlling apparatus with which traction control of a vehicle in which driving wheels are rotated by a motor may be realized in a simple construction.SOLUTION: A traction controlling apparatus 100 suppressing slide of a driving wheel in a vehicle where the driving wheel is rotated by a motor, comprises: an actual angular acceleration calculation part 110 having a function for calculating actual angular acceleration of the motor based on rotational position of a rotor in the motor; an expected angular acceleration calculation part 130 having a function for calculating expectation angular acceleration of the motor, based on information including an output torque value of the motor; a slide detecting part 140 detecting a slide state of the driving wheel by comparing a change amount sa1 in the actual angular acceleration per unit time and a change amount sa2 in the expectation angular acceleration per unit time; and an output torque value controlling part 150 controlling an output torque value of the motor based on the sliding state of the driving wheel detected by the slide detecting part 140.SELECTED DRAWING: Figure 3
