The development strategy of industry state has achieved achieves significantly.The more and more staff of the development need of Chinese industrial at present, with
The high wage of this factory simultaneously has attracted a large amount of peasant to leave local to work into factory.Cause a large amount of farmland not busy in this way
Set, and if someone contracts these public lands and plants mechanization of agriculture easy to accomplish at this time, and push Chinese tradition small peasant economy
Transition.Traditional agricultural machinery has higher requirements to driver, and cost of labor higher and higher at present increases farmer
Burden, since crop planting and harvesting time are all relatively anxious, it is necessary to complete that crop could not be influenced in defined period
Harvest.It is easy to cause high professional qualification driver insufficient in this way, and the development especially agricultural machinery self-navigation skill of precision agriculture at present
The application of art reduces the requirement to driver, and common driver can reach high professional qualification driving using self-navigation vehicle
The effect that employee makees, and driver does not have to moment steering wheel rotation, reduces the labor intensity of driver and improves agricultural machinery
The consistency of work.Tractor auxiliary drives the lateral deviations controlled between tractors and preset path more at present and course angle is inclined
Difference makes tractor along preset straight-line travelling.But most tractor throttle and brake can not automatically control, when tractor is at the edge of a field
When auto-steering, since speed can not automatically control, needs the artificial edge of a field to turn to, be otherwise easy to cause tractor turning radius mistake
Greatly, tractor can be made to roll when speed is excessive serious.Therefore tractor speed control seems for self-navigation tractor
It is increasingly important.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of tractor double acting E-Gas and brake control systems
System, when which makes tractor be in turning, the control of the control cooperation self-actuating brake part of auto-throttle part
System preferably completes the control of tractor speed.
In order to solve the above technical problems, the utility model uses following technological means:
A kind of tractor double acting E-Gas and brake control system, including steering controller, with steering controller electricity

Cable drum, brake encoder, brake encoder is for detecting cable drum rotational angle；Pacify in the shaft of throttle motor
Load connects throttle encoder, and brake encoder, throttle encoder are electrically connected with electric machine controller respectively.
Compared with prior art, the feature protruded is:
The same electric machine controller of the control system of the technical program simultaneously controls brake motor, throttle motor,
When tractor is turned, electric machine controller receives corresponding signal, controls brake motor and oil by motor drive module
Door motor；When speed is excessively high, brake motor drives brake actuating mechanism to brake, and stay-supported type displacement sensor can be in real time
Detection brake pedal displacement and corresponding signal is transmitted to electric machine controller, realization is accurately braked；Torque sensor is used for
Torque when brake motor work is detected, the excessive damage for causing automatic brake mechanism of motor torque is prevented；When throttle motor obtains
To after corresponding signal, change the revolving speed of E-Gas rotating mechanism, to realize the change of throttle output signal, cooperates braking machine
Structure and change engine power output.
Therefore this control system, when so that tractor being in turning, the control of auto-throttle part cooperates self-actuating brake part
Control, preferably complete tractor speed control.
Further optimal technical scheme is as follows:
The motor drive module is electrically connected by switch module with throttle motor.
By the way that switch module is arranged, can manually control in brake process, whether throttle motor is according to the control of this system
Cooperate the work of brake motor.
The electric machine controller is electrically connected by CAN bus with steering controller.
By the way that CAN interface is arranged in electric machine controller, steering controller is connected using CAN bus, realizes motor control
Communication between device and steering controller processed.
The torque sensor is flange type torque sensor.
Flange type torque sensor is fixed between ring flange by bolt, and easy for assemble or unload, use cost is low.
Detailed description of the invention
Fig. 1 is the circuit theory schematic diagram of the utility model.
Description of symbols: 1- steering controller；2- electric machine controller；3- motor drive module；4- brake motor；5- is held
