<p>Disclosed is a hybrid drive device capable of alleviating occurrences of power recirculation and reducing the occurrence of shocks and drive power interruptions when changing modes. The disclosed hybrid drive device comprises a power splitting device, further comprising a split input rotation element (E1), a reaction rotation element (E2), and an output rotation element (E3); and a transmission, further comprising a transmission input rotation element (E4), a first output rotation element (E6), a second output rotation element (E7), and a fixed rotation element (E5). The transmission input rotation element (E4) is drivingly connected to a second rotary electrical machine, and the fixed rotation element (E5) is anchored to a non-rotating member. The hybrid drive device further has the capability to switch between a first split mode, wherein the transmission input rotation element (E4) and the output rotation element (E3) are drivingly connected via the first output rotation element (E6); and a second split mode, wherein the transmission input rotation element (E4) and the split input rotation element (E1) are drivingly connected via the second output rotation element (E7). A prescribed first relative rotation velocity ratio (?1) and second relative rotation velocity ratio (?2) are set to different values.</p> |
