Abstract： |
The invention relates the fuel battery coach controlling method on base of the CAN bus internet communication used for hybrid power system, using the direct converting means to carry out energy management control. The CAN bus sends the main voltage signal VDC/DC, motor rotation rate signal rmotor and throttle pedal signal Acc_ps to full control device; in full control device looking up goal torque Tmotor and calculate demand total power Pmotor, auxiliary device power PAUX and accumulator charge-discharge power Pbat; calculate DC/DC output current IDC/DC; IDC/DC passes first order filtration, after meeting the DC/DC converter dynamic regulator course, then the full control device sends it to DC/DC control device by CAN bus, and realize the DC/DC current control. The invention can realize the accurately control of load power, and provide the flat form for any kind of energy controlling method; the charge and discharge state provided by secondary energy can be controlled; the integral efficiency of power system is improved. |
