FIELD: transportation.
SUBSTANCE: hybrid vehicle comprises an internal combustion engine, a motor, a transmission, a high-voltage battery supplying energy to the motor through the inverter. There is also a cooling mechanism with a pump circulating the cooling liquid, thereby cooling the inverter, a cooling liquid temperature measuring device and a low-voltage battery supplying energy to the pump. Under starting conditions with a high cooling liquid temperature, when the vehicle is switched on by means of the driver's key, the pump is started before energy is supplied from the high-voltage battery to the inverter.
EFFECT: improved cooling of the inverter.
