Method of controlling temperature

摘要

A method of controlling the temperature of an engine of a vehicle, such as an internal combustion engine and/or the temperature of one or more auxiliary components of the vehicle, such as a cabin heater for the vehicle includes monitoring one or more parameters of the engine including the temperature of the engine. Optionally data relating to the temperature of the engine is feedback to a control unit. The method includes monitoring one or more requirements of the one or more auxiliary components of the vehicle and/or monitoring one or more parameters of the one or more auxiliary components of the vehicle. In dependence upon said monitoring, the method includes selecting a cooling mode for a cooling system disposed about said engine and said one or more auxiliary components.

1. A method of controlling a temperature of an engine of a vehicle and/or of one or more auxiliary components of the vehicle, the method comprising:
(i) monitoring one or more parameters of the engine including the temperature of the engine; (ii) monitoring requirements of the one or more auxiliary components of the vehicle and/or monitoring one or more parameters of the one or more auxiliary components of the vehicle; and (iii) in dependence upon said monitoring, selecting a cooling mode for a cooling system disposed about said engine and said one or more auxiliary components, wherein said selecting a cooling mode is carried out at least in part by a control means and wherein each of a plurality of cooling modes is defined by:
(i) a flow rate at which coolant is output by a pump of the cooling system; and(ii) the route(s) about the cooling system open to the flow of coolant, whichroute(s) is determined in dependence upon whether one of more valve means comprised within the cooling system is closed or open, and wherein said control means is configured and arranged to actively and passively control said one or more valve means to open or to close one or more fluid conduits comprised within the cooling system, thereby controlling the route(s) available for the flow of coolant about the cooling system and thereby activating the selected cooling mode.
