Engine control device and engine control method

摘要

A control device is provided for an engine equipped with an electric oil pump for circulating coolant, and having a flow rate of the coolant restricted, when a temperature of the coolant is lower than a threshold value, as compared to a case where the temperature of the coolant is equal to or higher than the threshold value, and the engine control device includes a coolant temperature sensor detecting a temperature of the coolant, and a control unit stopping the engine in accordance with the temperature to be detected by the coolant temperature sensor after the pump is driven so as to increase the flow rate of the coolant, in a case where the flow rate of the coolant is restricted.

1. A control device for an engine equipped with a pump that circulates coolant, and having a flow rate of the coolant restricted, when a temperature of said coolant is lower than a threshold value, as compared to a case where the temperature of said coolant is equal to or higher than said threshold value, the control device comprising:
a coolant temperature sensor that detects a temperature of said coolant; and a control unit that drives said pump so as to increase the flow rate of said coolant when the temperature detected by said coolant temperature sensor rises to a predetermined temperature lower than said threshold value, and stops said engine when a condition is satisfied including at least a condition that the temperature detected by said coolant temperature sensor after said pump is driven so as to increase the flow rate of said coolant is higher than a lower limit value lower than said predetermined temperature, in a case where the flow rate of said coolant is restricted.
