Abstract

The invention relates to a distributed-driven electric automobile and a control method thereof. The distributed-driven electric automobile comprises a main controller, four driving wheels with hub motors correspondingly and motor drivers used for driving all the hub motors, and braking systems are arranged in all the driving wheels. When an accelerator pedal is triggered, the main controller assigns the corresponding motor rotating speeds and rotating torque through all the motor drivers to drive all the hub motors to enable the driving wheels to rotate; and when a braking pedal is triggered, the main controller is suitable for braking the hub motors through the braking systems. According to the distributed-driven electric automobile, a power supply management system is utilized to drive the four hub motors through the motor drivers correspondingly, and the driving wheels are driven to work, so that dependence on oil chemical energy of diesel is effectively reduced, energy strategy transformation is realized, the working noise is reduced, pollution emissions are reduced, the environment is effectively protected, and the market prospects are wide.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a distributed drive electric vehicle and a control method thereof. Background technique [0002] At present, petrochemical energy is in short supply, and oil is a non-renewable resource in the short term, which leads to repeated rises in oil prices, noisy diesel engines, and serious environmental pollution after diesel combustion. Based on the consideration of environmental protection, energy cost reduction, especially energy strategic transformation, a new type of distributed drive electric vehicle using electric energy and driven by hub motors was invented. Contents of the invention [0003] The purpose of the present invention is to provide a distributed drive electric vehicle and its control method, which utilizes the power management system to drive the corresponding in-wheel motor through the motor driver to make the driven wheels rotate, so that the whole vehicle can wal...
