Abstract
A method and control arrangement for controlling operation of a fan in a cooling system of a vehicle, wherein operation of the fan is controlled based on a temperature of a coolant in the coolant system meeting a set-temperature of the coolant. The method comprises monitoring an engine oil temperature of an engine of the vehicle during a plurality of driving cycles with the vehicle; and adjusting the set-temperature of the coolant based on a measure indicative of a plurality of maximum temperatures of the engine oil during the plurality of driving cycles.
Claims17
A method for controlling operation of a fan in a cooling system of a vehicle, wherein operation of the fan is controlled based on a temperature of a coolant in the coolant system of the vehicle meeting a set-temperature of the coolant, the method comprising:
- monitoring, while the vehicle is operating, an engine oil temperature of an engine of the vehicle during a plurality of selected driving cycles of the vehicle;
- determining a measure indicative of a plurality of maximum engine oil temperatures monitored during the plurality of driving cycles of the vehicle;
- and
- adjusting the set-temperature of the coolant for use in subsequent operation of the vehicle based on the measure indicative of a plurality of maximum temperatures of the engine oil monitored during the plurality of driving cycles of the vehicle.
A computer program product stored on a non-transitory computer-readable medium, said computer program product for controlling operation of a fan in a cooling system of a vehicle, wherein operation of the fan is controlled based on a temperature of a coolant in the coolant system of the vehicle meeting a set-temperature of the coolant, wherein said computer program product comprising computer instructions to cause one or more computing devices to perform the following operations:
- monitoring, while the vehicle is operating, an engine oil temperature of an engine of the vehicle during a plurality of selected driving cycles of the vehicle;
- determining a measure indicative of a plurality of maximum engine oil temperatures monitored during the plurality of driving cycles of the vehicle;
- and
- adjusting the set-temperature of the coolant for use in subsequent operation of the vehicle based on the measure indicative of a plurality of maximum temperatures of the engine oil monitored during the plurality of driving cycles of the vehicle.
A control arrangement for controlling operation of a fan in a cooling system of a vehicle, wherein operation of the fan is controlled based on a temperature of a coolant in the coolant system of the vehicle meeting a set-temperature of the coolant, and wherein the control arrangement is configured to:
- monitor, while the vehicle is operating, an engine oil temperature of an engine of the vehicle during a plurality of selected driving cycles of the vehicle;
- determine a measure indicative of a plurality of maximum engine oil temperatures monitored during the plurality of driving cycles of the vehicle;
- and
- adjust the set-temperature of the coolant for use in subsequent operation of the vehicle based on the measure indicative of a plurality of maximum temperatures of the engine oil monitored during the plurality of driving cycles of the vehicle.
A cooling system for a vehicle, wherein the cooling system comprises:
- a fan;
- a cooling circuit configured to circulate a coolant;
- and
- a control arrangement for controlling operation of the fan, wherein operation of the fan is controlled based on a temperature of a coolant in the coolant system of the vehicle meeting a set-temperature of the coolant, and wherein the control arrangement is configured to:
- monitor, while the vehicle is operating, an engine oil temperature of an engine of the vehicle during a plurality of selected driving cycles of the vehicle;
- determine a measure indicative of a plurality of maximum engine oil temperatures monitored during the plurality of driving cycles of the vehicle;
- and
- adjust the set-temperature of the coolant for use in subsequent operation of the vehicle based on the measure indicative of a plurality of maximum temperatures of the engine oil monitored during the plurality of driving cycles of the vehicle.
A vehicle comprising a cooling system, said cooling system comprising:
- a fan;
- a cooling circuit configured to circulate a coolant;
- and
- a control arrangement for controlling operation of the fan, wherein operation of the fan is controlled based on a temperature of a coolant in the coolant system of the vehicle meeting a set-temperature of the coolant, and wherein the control arrangement is configured to:
- monitor, while the vehicle is operating, an engine oil temperature of an engine of the vehicle during a plurality of selected driving cycles of the vehicle;
- determine a measure indicative of a plurality of maximum engine oil temperatures monitored during the plurality of driving cycles of the vehicle;
- and
- adjust the set-temperature of the coolant for use in subsequent operation of the vehicle based on the measure indicative of a plurality of maximum temperatures of the engine oil monitored during the plurality of driving cycles of the vehicle.
