Amphibious vehicle torque control method based on power distributor

Abstract

The invention discloses an amphibious vehicle torque control method based on a power distributor. The amphibious vehicle torque control method comprises an engine ECU, wherein a standard characteristic curve is preset in the engine ECU; when an amphibious vehicle is in an overwater driving mode or a shore driving mode, the engine ECU obtains output torque according to the standard characteristic curve; a revised characteristic curve is further preset in the engine ECU; in an interval that the engine rotating speed V is greater than or equal to V1 and less than or equal to V2, under the condition of the same engine rotating speed V, the obtained output torque obtained by the engine ECU according to the revised characteristic curve is less than the obtained output torque obtained by the engine ECU according to the standard characteristic curve; and when the amphibious vehicle is in a road driving mode and an amphibious driving mode, an engine outputs corresponding torque according to the revised characteristic curve. According to the amphibious vehicle torque control method, parallel transmission of two sets of power on land and water is realized, and meanwhile, torque overload of a gearbox, a drive axle, a transfer case and a transmission shaft in the working process is effectively prevented, so that a transmission assembly with relatively small torque capacity can be selected, and the purposes of reducing the weight of the whole vehicle and facilitating general arrangement are achieved.

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 Inland rivers and other narrow areas. [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 ...

AI Technical Summary

Problems solved by technology

This invention can realize the power distribution of one engine to the land driving system and the water driving system according to the needs of actual working conditions. However, there may be gearboxes, drive Damage to bridges, transfer cases, drive shafts due to engine output torque overload
