Abstract
A system that may include an engine, and a fan configured to vary a measured engine temperature of the engine during operation. A vehicle controller may also be provided having one or more processors that may be configured to determine an ice risk characteristic of the engine, operate the fan to cool the engine based on the ice risk characteristic, and operate the fan to rotate in reverse based on the ice risk characteristic.
Claims20
A system comprising:
- a controller having one or more processors configured to:
- operate a fan in forward to cool an engine in response to a measured engine temperature being hotter than a determined first engine threshold temperature;
- determine an ice risk characteristic of the engine;
- operate the fan to rotate in reverse based at least in part on the ice risk characteristic;
- and
- wherein the controller is configured to operate the fan in pulses sufficient to shake liquid from the fan.
3 more elements
A control system comprising one or more processors configured to:
- determine an ice risk characteristic of an engine;
- operate a fan to cool the engine when a measured engine temperature is greater than a determined first engine threshold temperature;
- operate the fan to rotate in reverse to prevent formation of ice on the fan based at least in part on the ice risk characteristic when a measured engine temperature is below the determined first engine threshold temperature;
- and
- operate the fan in pulses sufficient to shake water from the fan.
