Abstract

The invention provides a double-hub electronic motor electrical differential and speed regulation integrated controller. A control signal integrated adjusting unit module, a right wheel speed signal preprocessing module, a right wheel pre-driving unit module, a left wheel pre-driving unit module, a left wheel speed signal preprocessing module, a left hub electrical motor controller, a right hub electrical motor controller, a driving module unit and a monolithic computer are arranged inside the double-hub electrical motor electronic differential and speed regulation integrated controller. The double-hub electrical motor electronic differential and speed regulation integrated controller is characterized in that an electronic differential mechanism, the left hub electrical motor controller and the right hub electrical motor controller are combined into a whole inside the double-hub electrical motor electronic differential and speed regulation integrated controller simultaneously, and all components inside the double-hub electrical motor electronic differential and speed regulation integrated controller are of module structures. Meanwhile, a control signal and speed feedback signal processing module needed by an electric vehicle is arranged inside the controller, pre-control circuits and terminal driving circuits of a left electrical motor and a right electrical motor are inserted in the controller, and thus the fact that a control assembly of the electric motor driven by a double-hub electrical motor has differential control in turning, speed control in driving, stop control in temporary stop and anti-theft control in parking is guaranteed.

Description

technical field [0001] The invention relates to a control device for an electric vehicle driven by double-hub motors, in particular to a centralized controller for electronic differential speed and speed regulation suitable for a four-wheel electric vehicle driven by double-hub motors. Background technique [0002] The known four-wheel electric vehicle is generally equipped with a front drive axle or a rear drive axle, and the front drive axle or the rear drive axle is equipped with a mechanical differential and a reduction device, and the permanent magnet DC brushless motor is directly installed on the drive axle. , driven by the DC brushless motor controller, the four-wheel electric vehicle is pushed forward, backward or turned. With such a driving method, due to mechanical loss, the energy transfer efficiency of the motor and the flexibility of following the four-wheel electric vehicle are greatly reduced. [0003] At present, the development of electric vehicles from th...
