Embodiment

[0021] Such as figure 1 As shown, an electronic differential control system includes a drive motor 1, a steering motor 2, a wheel 3, an encoder 4, a Hall sensor 5, an electronic differential controller 6 and a speed reducer 7, and the drive motor 1 has 4, the wheels 3 have 4, and each of the wheels 3 corresponds to one of the driving motors 1, and each of the driving motors 1 and the wheels 3 is connected with a reducer 7, 4 The drive motor 1 drives the corresponding wheels 3 to provide forward power; the steering motor 2 provides steering power for the wheels 3; the encoder 4 calculates the number of output pulses of the photoelectric encoder per second. The number can reflect the current speed of the drive motor 1, which is used to provide two pulse signals with a phase difference of 90 degrees when judging the direction of rotation, and cooperates with the steering motor 2 to control the steering; the Hall sensor 5 is used for accurate The rotational speeds of the four dri...

Abstract

The invention discloses an electronic differential control system, which solves the problems that an error occurs in the control process of an existing mechanical differential, can not realize preciseadjustment, has large mechanical power transmission loss, and is not suitable for use of an electric vehicle. The control system includes driving motors, a steering motor, wheels, an encoder, a Hallsensor, an electronic differential controller, and a reducer, wherein the driving motors have four, the wheels have four, and each wheel corresponds to one of the driving motors, and a speed reducer is connected between each of the driving motors and the wheels, and the four driving motors respectively drive the corresponding wheels to provide forward power for the wheels; the steering motor provides steering power to the wheels. The invention has the advantages of simple structure, accurate control and independent control of the rotational speeds of four wheels of an electric vehicle, and mutual non-interference and the like.

Description

technical field [0001] The invention relates to the technical field of differential gears, in particular to an electronic differential gear control system. Background technique [0002] At present, along with the improvement of people's living standards, various styles of automobiles pour into people's field of vision, and people's travel and transportation are inseparable from automobiles. Among the parts of the car, the differential plays an important role in the smooth running and steering of the car. When the car is driving on a turning road or a curve, in order to achieve the purpose of turning, the inner and outer wheels should have a certain degree of Speed ​​difference, ie differential speed. For example, when turning right, the center of the circle is on the right side, and the track of the left wheel is longer than that of the right wheel in the same time, so the left wheel turns faster. To achieve this effect, you have to pass the difference speed to adjust. ...
