The invention provides a control method for integrated dual-current electric transmission. The electronically controlled dual-current steering mechanism is composed of a steering motor, a direct drive motor, a steering motor controller, a steering motor controller, a double-current transmission box, left and right side transmissions, and left and right wheel speeds. The steering speed control system composed of sensors controls the speed and direction of rotation of the converging planetary sun gears on both sides through two-way stepless adjustment of the steering motor. The output of the dual-flow transmission on both sides produces a speed difference, thereby realizing stepless steering of the vehicle. The target speed of the steering motor is obtained by the target speed of the inner tire and the target speed of the outer tire, so as to control the transmission of the dual-flow transmission box. The output on both sides of the dual-flow transmission generates a speed difference, thereby realizing stepless steering of the vehicle.
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...
