Title:
DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/031089
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide, for a drive system for a hybrid vehicle using both an engine and a motor, a compact configuration that allows the heat generated by an inverter to be used to warm up the engine and allows the inverter to be cooled stably. This drive system for a hybrid vehicle is provided with a first flow channel (5) connecting the engine (1) and a loop selection part (2), a second flow channel connecting the loop selection part and the engine across a cooler (3) for a motor-driving inverter (11) and a pump (4) for circulating a coolant, and a third flow channel (9) connecting the engine or first flow channel to the loop selection part across a radiator (8). When the coolant has a temperature less than a desired temperature necessary for the warming-up of the engine (1), the loop selection part (2) selects a first circulation loop (7) from the first flow channel to the second flow channel for the coolant to circulate in. When the temperature exceeds the desired temperature, the loop selection part (2) selects a second circulation loop (10) from the third flow channel to the second flow channel for the coolant to circulate in.
