To provide a landing propriety determination device for amphibian vehicle capable of determining the propriety of landing of an amphibian vehicle while considering prevention of occurrence of an engine trouble caused by excessive high exhaust temperature of exhaust gas in landing the amphibian vehicle from water surface to land.SOLUTION: A landing propriety determination device for amphibian vehicle includes: a determined maximum injection amount calculation portion for calculating a determined maximum injection amount which is a maximum injection amount of a fuel injected to an engine when an amphibian vehicle lands from water surface to land and with which an exhaust temperature of an exhaust gas discharged from the engine is less than a predetermined set temperature; and a maximum landing angle calculation portion for calculating a maximum landing angle with which the amphibian vehicle is capable of landing from water surface to land in a case where the fuel of the determined maximum injection amount is injected to the engine.SELECTED DRAWING: Figure 2
【課題】水陸両用車が水上から陸地に上陸する際において、排気の排気温度が高温となり過ぎることによるエンジン不具合の発生防止を考慮した水陸両用車の上陸可否判定を行なうことができる水陸両用車の上陸可否判定装置を提供する。【解決手段】水陸両用車の上陸可否判定装置は、水陸両用車が水上から陸地に上陸する際におけるエンジンに噴射される燃料の最大噴射量であって、エンジンから排出される排気の排気温度が予め定められている設定温度未満となる最大噴射量である決定最大噴射量を算出する決定最大噴射量算出部と、エンジンに決定最大噴射量の燃料を噴射した場合において、水陸両用車が水上から陸地に上陸可能な最大上陸角度を算出する最大上陸角度算出部と、を備える。【選択図】図2
