PROBLEM TO BE SOLVED: To provide a rotary electric machine temperature estimation device of an engine electric hybrid vehicle reducing estimated errors caused by heating of a variator.SOLUTION: A rotary electric machine temperature estimation device of an engine electric hybrid vehicle includes a non-stage transmission 30 and a rotary electric machine 100. The non-stage transmission 30 includes a variator having a primary pulley 31, a secondary pulley 32, and an annular power transmission member 33, and an oil pump 35 for supplying oil to the variator. The rotary electric machine 100 is directly connected to the primary pulley 31 or the secondary pulley 32 and is passed with at least a part of oil therein. The rotary electric machine temperature estimation device includes variator heating estimation means and temperature estimation means for correcting the temperature of oil on the basis of estimated heating value of the variator.SELECTED DRAWING: Figure 3
