Beschreibung
Zusammenfassung:	A vehicle includes a chassis, tractive elements configured to support the chassis, a primary driver configured to output mechanical energy to at least one of the tractive elements to drive the vehicle, a coolant circuit, a fan assembly, and a controller. The coolant circuit includes a thermal energy interface configured to transfer thermal energy from the primary driver to coolant and a radiator configured to receive the coolant. The fan assembly includes a hydraulic pump coupled to the primary driver, a hydraulic motor fluidly coupled to the hydraulic pump, a fan coupled to the hydraulic motor and configured to provide air flow to the radiator, and an actuator configured to vary a displacement of at least one of the hydraulic pump and the hydraulic motor. The controller is configured to control the actuator to vary a speed of the fan based on telematics data.
