Document Type and Number:
Japanese Patent JP6766487
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric vehicle controller which improves torque imbalance of a plurality of induction motors, prevents idling and sliding, and improves acceleration/deceleration performance and ride quality.SOLUTION: An electric vehicle controller for driving wheels of an electric vehicle by a plurality of induction motors 5A, 5B connected in parallel to each other on an output side of one inverter 3 comprises: means 7-9 for generating a torque command value and a magnetic flux command value according to a rotation speed equivalent value and an operation command of the motor; and control calculation means 12 for generating an output voltage command value of the inverter 3 using the torque command value, the magnetic flux command value, the rotation speed equivalent value, and currents of the induction motors 5A, 5B. When driving the electric vehicle while reducing the torque command value to be smaller than the maximum torque command value, the magnetic flux command value is reduced to be smaller than the magnetic flux command value at the maximum torque command value and is given to the control calculation means 12.SELECTED DRAWING: Figure 1
