Title:
ELECTRIC VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2023068833
Kind Code:
A
Abstract:
To provide a technique capable of accurately controlling operation of a DC-DC converter.SOLUTION: A control device is mounted on an electric vehicle in which a motor generator driving wheels is connected to a battery through a DC-DC converter. The control device is capable of executing the processes to: acquire a target value of output voltage of the DC-DC converter; acquire a measurement value of the output voltage of the DC-DC converter; acquire a direction of reactor current flowing in a reactor of the DC-DC converter; and execute feedback control of operation of the DC-DC converter in accordance with a deviation between the target value and the measurement value of the output voltage. The control device may include a process to determine a different feedback gain depending on the direction of the reactor current in the process to execute the feedback control.SELECTED DRAWING: Figure 2
