CONTROL METHOD FOR ENGINE THERMAL MANAGEMENT

摘要

A control method for engine thermal management that provides an electronic fan clutch and an electronic water pump in cooperation with an operation of an electronic thermostat, thereby achieving efficient engine thermal management and reducing a loss of load. The control method includes the steps of obtaining an engine coolant temperature and engine driving information and calculating a required fan rotational speed based on the obtained current coolant temperature information and the obtained engine driving information. The method calculates a control value for controlling a rotational speed of a cooling fan and checks a current operating state of the electronic thermostat. The method determines whether to operate the electronic water pump and control the cooling fan rotational speed based on the checked current operating state of the electronic thermostat, and controls the electronic water pump and the electronic fan clutch of the cooling fan based on the determination result.

1. A control method for engine thermal management, the control method comprising:
obtaining an engine coolant temperature and engine driving information; calculating a required fan rotational speed based on the obtained current coolant temperature information and the obtained engine driving information; calculating a control value for controlling a rotational speed of a cooling fan having an electronic fan clutch so that the rotational speed becomes the required fan rotational speed; checking a current operating state of an electronic thermostat; and determining whether to operate an electronic water pump and whether to control the cooling fan rotational speed using the control value based on the checked current operating state of the electronic thermostat, and controlling the electronic water pump and the electronic fan clutch of the cooling fan based on the determination result.
