A Torque Control Method for Amphibious Vehicle Based on Power Splitter

Abstract

The invention discloses a torque control method for an amphibious vehicle based on a power splitter, which includes an engine ECU. A standard characteristic curve is preset in the engine ECU. When the amphibious vehicle is in the water driving mode or the parking driving mode, the The ECU obtains the output torque according to the standard characteristic curve, and the modified characteristic curve is also preset in the engine ECU. 1 ≤Engine speed V≤V 2 In the interval of , under the condition of the same engine speed V, the obtained output torque obtained by the engine ECU according to the revised characteristic curve is smaller than the obtained output torque obtained by the engine ECU according to the standard characteristic curve; when the amphibious vehicle is in the road driving mode and the amphibian driving mode, The engine outputs the corresponding torque according to the revised characteristic curve. The invention not only realizes the parallel transmission of two sets of power on land and water, but also effectively prevents the torque overload of the gearbox, drive axle, transfer case, and transmission shaft during the working process, so that the transmission assembly with a small torque capacity can be selected to reduce the The weight of the whole vehicle is convenient for the purpose of general layout.

Description

technical field [0001] The invention discloses a power distributor and a control method, which belong to the technical field of amphibious vehicles, and specifically discloses a torque control method and a control method of an amphibious vehicle based on a power distributor. Background technique [0002] Amphibious vehicles are special-purpose vehicles, which are characterized by the functions of land driving and water navigation. Since the birth of amphibious vehicles, they have been mainly used in the field of military equipment construction. Although there are many countries equipped with amphibious vehicles, their development is relatively slow. Most of them are used in Narrow range such as inland rivers. [0003] Chinese invention patent CN111207182A discloses a clutch transfer case for amphibious vehicles, which includes a box body part I, a highly elastic coupling II, an input part III, an idler part IV, a transmission part V, an output part VI, The operating part VI...
