Hybrid vehicle
Document Type and Number:
Japanese Patent JP5987846
Kind Code:
B2
Abstract:
A hybrid vehicle provided with a battery 10, a boost converter 20, a first inverter 30, a second inverter 40, a first motor generator (MG) 50 connected to the first inverter 30, a second MG 60 connected to the second inverter 40, an engine 70 capable of driving the first MG 50, and a controller 90 which starts and stops the boost converter 20. When electric power transmitted between the battery 10 and the boost converter 20 is equal to or below a predetermined threshold, the boost converter 20 is stopped. When an actual boost voltage of the boost converter 20 reaches a predetermined threshold, the first MG 50 is driven by the engine 70. In this way, the system efficiency of a hybrid vehicle can be advantageously improved by efficiently maintaining the boost converter at a halt for a sufficiently long period.
