Document Type and Number:
WIPO Patent Application WO/2019/124311
Kind Code:
A1
Abstract:
Provided is a drive control device for a motor-mounted vehicle, the device being capable of detecting with good precision the temperature of a switching element of an inverter. This drive control device (16) of a motor-mounted vehicle is provided with: first and second temperature detection units (29, 29) provided at any one of a plurality of switching elements (33) of an inverter (25a) that drives one motor (6) and at any one of a plurality of switching elements (33) of an inverter (25a) that drives another motor (6) to detect the respective temperatures of the corresponding switching elements (33); and a temperature detection abnormality determination unit (30) that determines whether there is an abnormality in the temperature detection units (29) by mutually comparing the temperatures detected by the temperature detection units (29, 29). The temperature detection abnormality determination unit (30) determines that there is an abnormality in either of the temperature detection units (29) when the difference in temperatures detected by the first and second temperature detection units (29, 29) when each motor (6) is not energized is not within a stipulated normal range.
