The drived control method of detail the present invention below.
As shown in Figure 7, described driving control system comprises main control unit, control unit of engine, interior motor driving circuit, dispatch from foreign news agency drive circuit, store battery and electric quantity of power supply detection circuit; Described main control unit is connected with control unit of engine, interior motor driving circuit, dispatch from foreign news agency drive circuit, store battery and electric quantity of power supply detection circuit respectively;
When accumulator electric-quantity is sufficient, described limit power system of taking turns can carry out electric-only mode traveling. When pure electric low travels, store battery is powered to stator coil 2 by driving control system, and stator coil and the outer permanent magnet 14 of outer rotor form Permanent Magnet and Electric motivation (outer motor), and electromagnetism torque actuated outer rotor rotates. In addition when pure electric high-speed travels, the interior motor that store battery is consisted of to internal rotor coil power supply, internal rotor coil and outer rotor internal layer permanent magnet driving control system, it is possible to high-speed driving outer rotor rotates. Due to the reverse prevention effect of one-way clutch 6, internal rotor cannot reverse rotation, its reverse electromagnetism torque being subject to can not be delivered on internal wheel and semiaxis. By the difference work of inside and outside motor, two motors can be allowed can be operated in the interval of efficiency optimization, it is to increase electrically driven (operated) whole efficiency.
When electric quantity of power supply detects electric circuit inspection to accumulator electric-quantity deficiency, described limit power-driven system of taking turns can carry out hybrid power. During hybrid power, motor drives except for the outer, and the power (deriving from engine system) on semiaxis arrives internal rotor 11 through internal wheel 7, transmission idle pulley 16. Now, interior motor needs store battery to provide magnetizing current in the initial moment, store battery is powered to internal rotor coil 12 by driving control system, and internal rotor coil and outer rotor internal layer permanent magnet set up electromagnetic coupled effect, relies on electromagnetic torque that the power torque on internal rotor is delivered on outer rotor. When, after interior machine operation, after internal rotor rotating speed exceedes outer rotor, interior motor starts generating, and accumulators charging.
When hybrid power, according to vehicle movement power demand size, determine the working order of outer motor, when the vehicle movement speed of a motor vehicle is less, the driving power demand of vehicle is also less, and engine workload is not enough so that it is operated in economic zone, and that outer motor transfers generating state to, increase engine workload, impel engine operation can be operated in economic work district.
If the vehicle movement speed of a motor vehicle is relatively big, the driving power demand of vehicle becomes big thereupon, and engine workload can make it be operated in economic zone, and that outer motor can not participate in work.
In addition, described limit power-driven system of taking turns has braking energy recovering function, and during braking, different according to braking intensity, interior motor, outer motor can be changed into generator separately or together, absorb braking energy, and are translated into the charging of electric energy accumulators. If braking intensity is less, then in, motor is converted into generator, and in especially, motor electromagnetic moment is less, and its braking moment produced is little, and the ability reclaiming braking energy is also little. If braking strength demand is bigger, it is possible to outer motor is converted into generator, owing to outer motor is low speed high torque motor, after it is converted into generator, the braking moment of generation is also big, so braking energy can be absorbed in a large number. Certain inside and outside motor carries out electromagnetic braking simultaneously, then the effect of Brake energy recovery is certainly also best.
