Title:
VEHICLE CONTROLLER
Document Type and Number:
Japanese Patent JP2013162559
Kind Code:
A
Abstract:

To provide a vehicle controller for individually controlling motors independently provided in a pair of wheels, and having a simplified constitution.

A vehicle controller comprises: one inverter; a first motor connected to the inverter and a first wheel; a second motor connected to the inverter and a second wheel; and a voltage boosting/dropping converter provided between the first motor and the inverter. If the degree of a rotation variation in the first wheel is larger than the degree of a rotation variation in the second wheel, a voltage supplied from the inverter to the first motor is dropped by the voltage boosting/dropping converter (S4). If the degree of the rotation variation in the second wheel is larger than the degree of the rotation variation in the first wheel, currents supplied from the inverter to the first motor and second motor are reduced, and the voltage supplied from the inverter to the first motor is boosted by the voltage boosting/dropping converter (S5).
