Claim 1:
2. The thermal management system according to claim 1, further comprising a third temperature sensor that is located on the third flow path and that is configured to measure a third temperature of the heating medium, wherein:
the first temperature sensor is located on the first flow path at a part that does not constitute the third flow path;
the second temperature sensor is located on the second flow path at a part that does not constitute the third flow path;
a temperature of the heating medium in the third flow path is higher than the temperature of the heating medium in the first flow path and the temperature of the heating medium in the second flow path; and
in the second mode, the control unit
acquires the measured value of the first temperature from the first temperature sensor, the measured value of the second temperature from the second temperature sensor, and a measured value of the third temperature from the third temperature sensor at second predetermined time that is when a predetermined amount of time has passed since the third temperature started to rise,
acquires the estimated value of the first temperature, the estimated value of the second temperature, and an estimated value of the third temperature at the second predetermined time that are estimated values when the switching valve is not in the slightly open state, and
determines that the switching valve is in the slightly open state when the measured value of the first temperature is higher than the estimated value of the first temperature by a value greater than the first predetermined threshold, the measured value of the second temperature is higher than the estimated value of the second temperature by a value greater than the second predetermined threshold, and the measured value of the third temperature is lower than the estimated value of the third temperature by a value greater than a third predetermined threshold.
