Background technology
Along with the aggravation of environmental pollution, electronlmobil has become one of main developing direction of future transportation instrument because of its environmental protection, energy-saving advantages.Electronlmobil all will be played an important role in the public transport in future and transportation.
The drive motor controller that is used for electronlmobil in the market mostly can not the Direct Sampling acceleration pedal and the operation signal of brake pedal, but is sampled and processing is resent to electric machine controller by entire car controller.This processing mode is in electronlmobil climbing or cross when needing the emergency control motor rotation under the road conditions such as railway mouth, because the entire car controller processing signals needs the time, and to add that control signal is sent to the electric machine controller time, therefore often can not in time respond pedal signal, there is certain potential safety hazard in this in the driving procedure of electronlmobil.
The utility model content
At above-mentioned deficiency of the prior art, the purpose of this utility model is to provide a kind of can make electric machine controller Direct Sampling pedal signal, and improves the pure electric vehicle drive motor controller of driving safety.
The technical solution of the utility model: a kind of drive motor controller that is used for pure electric vehicle, it is characterized in that, comprise sampling module, conversion and control module, driver module and communication module, the acceleration pedal of described sampling module sampling electronlmobil and the operation signal of brake pedal, and this operation signal is transferred to described conversion and control module by connection lead; The conversion and control module is connected in the entire car controller of electronlmobil via described communication module, and the conversion and control module receives the motor that control and driving module behind the operation signal drives electronlmobil; Described sampling module has two-way analog quantity sample port, is used for gathering simultaneously described acceleration pedal and brake pedal signal.
Further technical scheme, described conversion and control module receives the signal that sampling module is gathered, and provides the torque control signal through computing and transfer to described driver module.
With respect to prior art, the utlity model has following beneficial effect:
Drive motor controller of the present utility model is owing to have a sampling module, the acceleration pedal that it can the Direct Sampling electronlmobil and the operation signal of brake pedal, and via the operation by driver module direct control motor after the conversion and control resume module.Therefore, be in climbing at electronlmobil, when needing the emergency control motor, can pass through electric machine controller direct control motor, and need not to control by car load control cutter by road conditions such as railway mouths.In addition, because conversion and control module of the present utility model also is connected with entire car controller by communication module, therefore can give electric machine controller with the various state transfer of motor rotation in time.Drive motor controller of the present utility model is safe and reliable, control is easy, can be connected with various entire car controllers and motor, has general applicability.
Description of drawings
Fig. 1 is the structural representation of the utility model drive motor controller.
Among the figure, 1-sampling module, 2-conversion and control module, 3-driver module, 4-communication module.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of drive motor controller that is used for pure electric vehicle, comprise sampling module 1, conversion and control module 2, driver module 3 and communication module 4, the acceleration pedal of wherein said sampling module 1 sampling electronlmobil and the operation signal of brake pedal, and this operation signal is transferred to conversion and control module 2, wherein, acceleration pedal and brake pedal are the existing parts of electronlmobil; Described conversion and control module 2 is handled described operation signals and is also controlled described driver module 3, and this conversion and control module 2 is connected in entire car controller on the described electronlmobil via described communication module 4; Described driver module 3 is the motor of the described electronlmobil of direct drive by the control of conversion and control module 2.
Described sampling module 1 has two-way analog quantity sample port (being the link port of sensor, probe, contact etc.), can gather acceleration pedal and brake pedal signal simultaneously.The analog signal of pedal sensor output converts digital signal to through sampling module 1, sends into conversion and control module 2 then.This sampling module specifically is provided with as follows: by increasing ADC(is analog-digital converter) sampling resolution or improve its sampling frequency, can effectively reduce quantizing noise.In addition, need to consider the real-time requirement.Described sampling module 1 carries out the digital averaging algorithm then by interrupting reading the A/D translation data.Finish so many computing twice break period in the interval, require the speed of treater to want fast on the one hand, require the processing time long as far as possible at interval on the other hand, therefore can realize by the pitch time of the adjacent interruption of suitable increase, the sampling rate that promptly reduces ADC realizes.Simultaneously, consider that from the angle that improves signal to noise ratio utilize oversampling technique, its sampling frequency is high more good more, but the real-time angle of handling from processor data, sampling frequency should not be too high.Final sampling module of the present utility model 1 selected 10 sampling precisions, the highest sampling frequency can reach 1 MHz.In addition, in order to guarantee the reliability of A/D modular converter work, also need to increase the consideration of reliability in the design, for example the sampled signal input end at ADC adds protective circuit.
Described conversion and control module 2 is accepted the signal that sampling module 1 is gathered, and sends torque signal to driver module 3 after handling as calculated.This conversion and control module 2 also is connected in entire car controller by communication module 4, described entire car controller also is the existing parts on the electronlmobil, by communication module 4, the various mode of operations that conversion and control module 2 can be moved to entire car controller feedback motor in time.
Described driver module 3 is used for the electrical motor of direct drive electronlmobil, therefore makes the motor of described battery-driven car have higher torque overload ability.
Described communication module 4 has CAN(Controller Area Network, controller local area network) communication function, it has digitalisation programming Control function.Described conversion and control module 2 is carried out communication by CAN communication and entire car controller, the related work state is delivered to entire car controller, make controller of the present utility model go for various vehicles like this, and can when the entire car controller fault, still can work independently, do not influence electronlmobil and normally move.
Therefore, drive motor controller of the present utility model is owing to have sampling module, its can the Direct Sampling electronlmobil acceleration pedal and the operation signal of brake pedal, and via the operation by driver module direct control motor after the conversion and control resume module.Therefore, be in climbing at electronlmobil, when needing the emergency control motor, can pass through electric machine controller direct control motor of the present utility model, and need not to control by entire car controller by road conditions such as railway mouths.In addition, because conversion and control module of the present utility model also is connected with entire car controller by communication module, therefore can give electric machine controller with the various feedback of status of motor rotation in time.Electric machine controller of the present utility model is safe and reliable, control is easy, can be connected with various entire car controllers and motor, has applicability preferably.
