Embodiment Construction

[0044] figure 1 It is the structural block diagram of the intelligent flywheel controller. The digital core circuit 1 is connected with the connector circuit 2, receives information from the vehicle controller 10 and the smart flywheel 8, and sends control signals to the smart flywheel 8. The digital core needs to apply a processor with both rich I / O interfaces and strong computing capabilities. This controller uses TI's TMS320LF2407 as the digital core.

[0045] The circuit 3 can receive instructions from the vehicle controller 10 , and can also send flywheel information to the vehicle controller 10 . The CAN communication circuit uses 6N137, TJA1050 and NML0505 to realize the isolated CAN transceiver circuit.

[0046] The PWM signal conversion and power drive circuit 4 is respectively connected with the circuit 2 , the smart flywheel 8 and the energy storage element 9 . The control signal from the circuit 1 is sent to the PWM signal conversion and power drive circuit 4 t...

Abstract

The invention belongs to a scope of a vehicle controlling device, in particular a flywheel controller of an intelligent engine and a controlling method of the flywheel controller. The invention comprises a digital core circuit (1), a connector circuit (2), a CAN communication circuit (3), PWM signal transformation and power driving (4), a rotor information detecting and handling circuit (5), a voltage and current detecting and handling circuit (6) and a power circuit (7). The controller adopts a combined hardware structure comprising an independent digital core daughter board and a mother board consisting of peripheral circuits and uses a control algorithm of direct flux to realize the controlling of the electromotion and power generation status of the intelligent flywheel. The controller can be connected with a plurality of speed sensors; the separate design of the daughter board and the mother board facilitates the maintenance and upgrading of the invention; the system performance is affected little by flywheel parameters; the torque responding speed is high, so the starting time of the engine is shorter and the electricity load capacity is stronger.

Description

technical field [0001] The invention belongs to the scope of vehicle control devices, in particular to an engine intelligent flywheel controller and a control method thereof. Background technique [0002] With the rapid increase of car ownership, the problems of energy consumption and exhaust emissions have become more prominent. The starter, generator and flywheel on the car engine are three independent components, which are used to drive the engine to rotate, charge the on-board battery and smooth the fluctuation of the crankshaft speed of the engine. [0003] The conventional vehicle engine with the above-mentioned structure starts slowly, and it is difficult to realize the function of idling and stopping, which causes excessive fuel consumption and exhaust emissions when the vehicle is started and idling; at the same time, the kinetic energy of the vehicle cannot be recovered when braking, and a large amount of available energy is wasted. waste. [0004] With the devel...
