State；
Driving condition, governor circuit receives the driving signal sent from driver, closes and drives generating change-over circuit, right
Mu balanced circuit is protected, the voltage of accumulator needed for confirmation driving electric automobile, if getting the voltage of accumulator less than setting
During definite value, governor circuit stops sending pulse drive signal to drive circuit, sends alarm signal to driver simultaneously, and prompting stores
Cell voltage is too low, drives motor not work, if the voltage getting accumulator is higher than setting value, governor circuit is according to letter
Number sensor detects driving motor rotor position signal, sends driving electricity after calculating the pulse signal needed for driving motor to
Road, drive pulse signal is carried out power amplification and is input to inverter circuit by drive circuit, and inverter circuit controls current switching also
The unidirectional current of accumulator being converted to three-phase alternating current flow to drive motor, so that driving motor work, electric automobile is transported
OK；
Brake energy recovery generating state, when governor circuit receives brake signal, closes drive circuit, to drive circuit
Protect with inverter circuit, simultaneously to driving generating change-over circuit to send pulse signal, drive generating change-over circuit again to surely
Volt circuit sends control signal, makes driving motor be converted to electromotor and reclaims the skidding energy of electric automobile, mu balanced circuit
Controlling the distribution of electromotor output electric energy, if during accumulator underfill electricity, the electric energy that electromotor exports is flowed to by mu balanced circuit
Accumulator and load, if accumulator is fully charged, the electric energy that electromotor is exported by mu balanced circuit only flows to load.
The present invention compared with prior art, this electric automobile driving electric motor control can drive electric automobile run,
Again can efficient recovery skidding energy, reach energy-saving and cost-reducing purpose, it is ensured that dynamic property during electric automobile during traveling, economy
Property, increase electric automobile continual mileage.
Accompanying drawing explanation
Fig. 1 is the control method block diagram of the embodiment of the present invention.
In figure: 1, governor circuit 2, drive circuit 3, inverter circuit 4, driving motor 5, accumulator 6, mu balanced circuit
