Abstract
A method for controlling a cooling system in a vehicle, may include an Exhaust Gas Recirculation (EGR) use determination step of determining whether to use EGR, a first coolant temperature management step of controlling a coolant temperature using a first coolant temperature map based on an output value reflecting engine operating conditions when driving the vehicle using the EGR, and a second coolant temperature management step of controlling the coolant temperature using a second coolant temperature map in which a coolant temperature of the second coolant temperature map may be set to be higher than a coolant temperature of the first coolant temperature map in a same engine operation region when driving the vehicle not using the EGR.
Claims12
A method for controlling a cooling system in a vehicle, comprising:
- an Exhaust Gas Recirculation (EGR) use determination step of determining whether to use EGR;
- a first coolant temperature management step of controlling a coolant temperature using a first coolant temperature map based on an output value reflecting engine operating conditions when driving the vehicle using the EGR;
- and
- a second coolant temperature management step of controlling the coolant temperature using a second coolant temperature map in which a coolant temperature of the second coolant temperature map is set to be higher than a coolant temperature of the first coolant temperature map in a same engine operation region when driving the vehicle not using the EGR.
A method for controlling a cooling system in a vehicle, comprising:
- an Exhaust Gas Recirculation (EGR) use determination step of determining whether to use the EGR;
- a first coolant temperature management step of controlling a coolant temperature using a first coolant temperature map based on an output value reflecting engine operating conditions when driving the vehicle using the EGR;
- an input step of receiving a value of NOx as an input;
- and
- a third coolant temperature management step of controlling the coolant temperature using a third coolant temperature map in which a coolant temperature of the third coolant temperature map is set to be lower than a coolant temperature of the first coolant temperature map in a same engine operation region when the value of the NOx is higher than a reference value for the NOx of a NOx map set according to an engine operation region.
