Title:
AMPHIBIOUS VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/084075
Kind Code:
A1
Abstract:
Provided is an amphibious vehicle with which it is possible to increase the driving power even when the engine rotational speed is low. When the engine rotational frequency is lower than a prescribed rotational frequency the fan flow volume of a fan is calculated on the basis of the fan outlet pressure (B1), the amount of heat exchange of a heat exchanger is calculated on the basis of the fan inlet temperature, the fan outlet temperature, and the fan flow volume (B2), a target fan rotational frequency is calculated on the basis of the engine rotational frequency and the heat exchange amount (B3), the fan rotational frequency is reduced so as to achieve the target fan rotational frequency (B4, B5), and the power transmitted to a travel device is increased, thereby increasing the drive torque (B6).
