Title:
MOTOR-DRIVEN SYSTEM FOR VEHICLE
Document Type and Number:
Japanese Patent JP2022135024
Kind Code:
A
Abstract:
To realize torque vectoring control with a simple configuration.SOLUTION: A power control device controls AC power in a first mode when a vehicle directly advances, and controls AC power in a second mode when a vehicle turns. In the first mode, the frequency of AC power is set so that slippage generated in a first induction motor and a second induction motor becomes smaller than slippage corresponding to stalling torque. In the second mode, the frequency of AC power is set so that slippage generated in the first induction motor and the second induction motor becomes larger than slippage corresponding to stalling torque. The power control device temporarily lowers the voltage of AC power in a process of changing the frequency of AC power when shifting a mode between the first mode and the second mode.SELECTED DRAWING: Figure 10
