Amphibious vehicle amphibious running mode conversion opportunity judgment method and device and vehicle

The invention provides an amphibious vehicle amphibious running mode switching opportunity judgment method and device and a vehicle. The method comprises the steps that a running mode switching request sent by a navigation bridge is received; responding to the driving mode switching request, and obtaining first state information of a suspension subsystem, second state information of a braking subsystem, third state information of a power subsystem and fourth state information of a steering subsystem; and according to the first state information, the second state information, the third state information and the fourth state information, the amphibious vehicle amphibious running mode conversion time is determined. According to the method, the advantage of information sharing of the whole amphibious vehicle is fully utilized, misjudgment of the switching opportunity caused by insufficient experience or misjudgment of a driver is made up, the accuracy of the switching opportunity of the amphibious vehicle amphibi
