Title:
COOLING CONTROL DEVICE, ELECTRIC SYSTEM, AND COOLING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/131598
Kind Code:
A1
Abstract:
According to the present invention, misrecognition of oil temperature is avoided, and the cooling capability of an electric component is appropriately controlled. A control device that controls cooling of a dynamo-electric machine for vehicle drive, wherein: the control device comprises a calculation unit that executes a prescribed calculation process, and a storage unit that can be accessed by the calculation unit. Each of first temperature information produced by a first temperature detection unit that detects the temperature of a first refrigerant by which heat exchange is performed with at least the dynamo-electric machine, second temperature information produced by a second temperature detection unit that detects the temperature of a second refrigerant by which heat exchange is performed at least with a winding of the dynamo-electric machine and which is cooled by the first refrigerant, third temperature information produced by a dynamo-electric machine temperature detection unit that detects the temperature of the dynamo-electric machine, and fourth temperature information produced by an outside air temperature detection unit that detects the temperature of outside air, is inputted. The second temperature information is verified using the first temperature information, the second temperature information, the third temperature information, and the fourth temperature information.
