Title:
CONTROL APPARATUS FOR VEHICLE
Document Type and Number:
Japanese Patent JP2023184288
Kind Code:
A
Abstract:
To maintain voltage of a capacitor connected to a power line between a relay and an inverter when traveling in a state where a main battery is separated from a traveling motor.SOLUTION: A control apparatus for a vehicle includes: a boost converter that outputs DC power after boosting to an inverter; a first capacitor connected to a first power line that connects a relay and the boost converter; a second capacitor connected to a second power line that connects the boost converter and the inverter; and a bidirectional DC/DC converter that boosts electric power from an auxiliary battery and outputs the boosted electric power to the first power line. During battery-less traveling in which the vehicle travels in a state where a main battery is separated from a traveling motor by opening a relay, when voltage of the first capacitor and voltage of the second capacitor are equal to or lower than a threshold, the bidirectional DC/DC converter is controlled so as to boost the electric power from the auxiliary battery and output the boosted electric power to the first power line.SELECTED DRAWING: Figure 1
