Problems solved by technology

However, due to the lack of mechanical connection between the two sets of drive units, the differences in the motors on both sides due to manufacturing errors, and the differences in road loads, it is impossible to structurally ensure that the wheels on both sides are synchronized when the vehicle is driving straight, which increases the difficulty of control and driving. operator fatigue

Abstract

The invention provides a double-power-source electric drive assembly with a load balancing device, which can expand the torque range and the rotating speed range covered by output of the electric drive assembly, can also improve the control stability of an electric automobile and ensure the straight driving stability of the electric automobile. The double-power-source electric drive assembly comprises the load balancing device, so that the load torque difference transmitted to motors on the two sides by wheels can be reduced when the vehicle runs straightly, and wheel desynchrony caused by therotating speed difference of the motors on the two sides can also be reduced. When torque vector control is carried out on vehicle steering, the output torque difference of the motors on the two sides can be increased, the yawing couple torque is rapidly generated to prevent the sideslip phenomenon which is difficult to control, and the control stability of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of hybrid vehicles, in particular to a dual power source electric drive assembly with a load balancing device. Background technique [0002] With the increasing production and ownership of automobiles in the world, the serious environmental pollution caused by internal combustion engine vehicles and the increasingly urgent global oil resources and energy crisis have forced countries all over the world to actively seek new energy vehicles. Due to the advantages of no air pollution, low noise, wide source of electric energy, high energy utilization rate, less heat radiation, and convenient use and maintenance, electric vehicles have attracted widespread attention and achieved great success in their promotion and technology development. . As electric vehicles need to face more and more complex working conditions and road conditions, users have higher and higher requirements for vehicle comfort and maneuverabil...
