Title:
CONTROL DEVICE OF ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2022183655
Kind Code:
A
Abstract:
To set an engine rotation position at a rotation position suitable for start.SOLUTION: A control device of an electric vehicle 1 includes: an engine (rotary engine 3); a motor (power generation motor 12) for generating power; a battery (high voltage battery 23); a first controller (engine ECU 25) for operating the engine; a second controller (motor ECU 26) for operating the motor; and a sensor (motor rotation sensor SN4). The second controller acquires information on a rotation position of the engine from the first controller during running of the motor for generating power, thereby determines a relative position relation between a rotation position of the engine and a rotation position of the motor, and monitors the rotation position of the engine on the basis of the relative position relation and a signal from the sensor, and the second controller confirms an engine stop position on the basis of the monitoring of the engine rotation position when the running of the motor for generating power is ended.SELECTED DRAWING: Figure 1
