Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.Method as described below may be used for
Any hybrid power and electric automobile.High voltage component is used for driving vehicle.Electric vehicle is used alone battery and drives,
Motor vehicle driven by mixed power uses internal combustion engine and battery jointly to drive.High pressure known to the present invention refers to greater than the electricity of 60 volts
Pressure.
As shown in Figure 1, it is shown that an exemplary high-voltage conducting wires system 00 in electric motor car.System 00 comprises one
Individual high-tension battery bag 30, can be accepted from extraneous the filling of vehicle by ac plug 10 and Vehicular charger 20
Electricity.High-tension battery bag 30 is through a dc-dc 40, to 12V system 50 (such as accumulator and low
Pressure load) electric power is provided.High-tension battery bag 30 also (includes that air-conditioning is inverse to electric heater 70 and electric air-conditioning 80
Become device 81 and compressor of air conditioner 82) electric power is provided.Most of energy of high-tension battery bag 30 and power for

230 by connecting the 231 time function conducts providing vehicle load moment of torsion and rotating speed to electric machine controller module 240
Input.The major function of electric machine controller module 240 determines that can the load that motor be driven to meet vehicle request be turned round
Square and rotating speed.The load torque asked by vehicle and rotating speed, compared with the driveability border driving motor,
May determine that load torque and the rotating speed driving motor can meet vehicle request.If the latter exceedes the former driving
Performance bounds, needs the request limiting vehicle load moment of torsion and rotating speed to the maximum allowed.Through processing, rationally
Vehicle load moment of torsion and rotating speed request 241 be delivered to 250 from 240 through connecting.Drive motor module 250,
Can be a simple efficiency collection of illustrative plates, electric efficiency be the function of motor speed and Motor torque.Can also be one
The equivalent circuit of individual complexity, feedback control loop of guaranteeing replacement.In order to obtain driving input end of motor 3 cross streams voltage and 3
Cross streams electric current, needs to set up complicated circuit model.The major function driving motor module 250 is that simulation is true
Drive the input-output characteristic of motor.This module by from vehicle load moment of torsion and rotating speed request by connect 251
Be converted to the electric power request of inverter module 260 outfan.Inverter module 260 can be one simple
Efficiency collection of illustrative plates, input and output conversion efficiency is the function of motor speed and moment of torsion.By connecting 261, inverter mould
The electric power request of block 260 input is delivered to Brake energy recovery controller module 270.The latter is braking
Energy feedback controller module, implements braking energy feedback control strategy, during calculating vehicle acceleration, deceleration, truly
Battery charging and discharging power request.Its performance and life-span all can be caused by overcharging or crossing to put of high-tension battery bag
Injury.Therefore, almost all of hybrid power and electric automobile are required for comprising braking energy feedback control strategy,
In train's simulation model framework, also it is necessarily increased such a module.Brake energy recovery controller module
270 through connecting the 271 real battery charging and discharging power request of output to high-voltage battery module 280.Finally
One high-voltage battery module 280 is asked according to charge-discharge electric power, and that implements high-tension battery bag electrically or also comprises heat
