Title:
ハイブリッド車両の制御装置
Document Type and Number:
Japanese Patent JP7099202
Kind Code:
B2
Abstract:
To provide a control device of a hybrid vehicle that can improve cooling performance to a first electric motor when the hybrid vehicle is in a travelling mode in which a power circulation state is generated.SOLUTION: In a hybrid vehicle 10, a cooling circuit 30 for a battery (a first cooling circuit) for a battery 14, a second cooling circuit 60 for electric motors for a first electric motor MG1 and a second electric motor MG2 and a cooling circuit 40 for a PCU (a second cooling circuit 70) are provided independently from one another, an AC capacitor 36 that radiates heat generated in the battery 14 is arranged on the windward side of cooling air, and a radiator 46 that radiates heat generated in the first electric motor MG1 and the second electric motor MG2 is arranged on a leeward side of the cooling air. When the hybrid vehicle 10 is in a first travelling mode in which a power circulation state where electric power generated by the second electric motor MG2 is consumed by the first electric motor MG1 is generated, rotation speed Ncon of a compressor 34 is lowered more than in a travelling mode different from the first travelling mode.SELECTED DRAWING: Figure 6
