The invention provides a control method for comprehensive double-current electric transmission. An electric control double-current steering mechanism is a steering speed regulation system composed ofa steering motor, a straight driving motor, a steering motor controller, the steering motor controller, a double-current transmission box, a left side transmission, a right side transmission, a left wheel speed sensor and a right wheel speed sensor. A rotating speed and a rotating direction of confluence planet row sun wheels on the two sides are controlled by adjusting the steering motor in a two-way stepless mode, a rotating speed difference is generated through double-current transmission and two-side output, and stepless steering of the vehicle is achieved. A target rotating speed of the steering motor is obtained through the target rotating speed of an inner side tire and the target rotating speed of an outer side tire, transmission of the double-current transmission box is controlled, the rotating speed difference is generated through double-current transmission two-side output, and the stepless steering of the vehicle is achieved.
Description
technical field [0001] The invention relates to a double-current electric transmission, in particular to a control method for a comprehensive double-current electric transmission. Background technique [0002] At present, most automobile gearboxes adopt the design of differential, which can solve the power distribution problem when the car is running normally and when one side of the tire slips, but the power distribution and driving of some special vehicles are obviously not up to the requirements. [0003] Therefore, there is a need for a new gearbox design, which can provide the normal differential function and at the same time have the function of making the vehicle rotate in situ to output driving force. CN201822252757.6 discloses a double-flow gearbox, which consists of a housing, a differential housing, bevel gear input shafts, transmission gears, differential gears, bevel gears, differential planetary gears, planetary gears, side gears and Bearing composition; reali...
