(2) acceleration pedal and brake pedal: the pedal aperture has reflected chaufeur to driving or the requirement of braking gross horsepower output, by transfer device the aperture of pedal is converted to electric quantity signal input whole-control system.
(3) dynamic assembly whole-control system: the core that is whole dynamic assembly.Receive the feedback signal of pedal signal and each parts, determine the mode of operation and the power output of each parts, and control command is imported the control unit of each parts by control algorithm.The control unit of each parts shown below receives and outputs to actr from the control command of whole-control system and with instruction, controls the running state of each parts and the power of requirement is provided; Status signal by each parts of sensor acquisition and pass whole-control system back simultaneously.
(4) engine assembly: comprise engine body, control unit of engine and actr.Control unit receives the control command from whole-control system, sends control command to actr, the mode of operation (opening or closing) of control driving engine, and regulate power according to control command and export.Simultaneously, the status signal and the tach signal of collection driving engine feed back to whole-control system.
(5) motor assembly: comprise motor body, inverter and control unit.Control unit receives the control command from whole-control system, send control command to inverter, the mode of operation (motoring condition or generating state) and the output characteristic of control motor, make motor provide the power of requirement, and status signal and the tach signal of gathering motor feed back to whole-control system according to control command.
(6) battery assembly: comprise battery body, battery manager and control unit.Control unit receives the control command from whole-control system, send control command to battery manager, the mode of operation (charge condition or discharge regime) of control battery makes battery provide the power of requirement according to control command, and status signal, electric quantity signal and the temperature signal of gathering battery feed back to whole-control system.
(7) clutch assembly: comprise clutch body master clutch and time power-transfer clutch, actr and control unit.Control unit receives the control command from whole-control system, send control command to actr, the mode of operation of control clutch (separate or engage) makes power-transfer clutch engage according to control command or separates, and the status signal of gathering power-transfer clutch feeds back to whole-control system.
(8) transmission assembly: comprise change-speed box body, actr and control unit.Control unit receives the control command from whole-control system, send control command to gear shifting operator, the mode of operation (gear shift or not gear shift) of control change-speed box makes change-speed box according to the control command gear shift, and the status signal and the gear signal of collection change-speed box feed back to whole-control system.
(9) mechanical braking sytem: comprise drg body, actr and control unit.Control unit receives the control command from whole-control system, sends control command to actr, and the mode of operation of control brake device (start or close) makes mechanical braking sytem that the brake torque of requirement is provided by control command.
The present invention is owing to motor connects with the power synthesizer by time power-transfer clutch, when gear shift, motor is separated with the power synthesizer, reduced rotor inertia, the gear shift stationary problem is improved, under driving engine works independently pattern, can realize that also motor separates with the power synthesizer, therefore, reduced waste of power, simultaneously, needn't carry out harsh control to motor again and require and can realize, the present invention improves 5%-10% than the fuel economy of present hybrid vehicle.
