Quicken operating condition; Accelerator pedal position amplification surpasses 10% and regards as the acceleration operating condition; In order to keep traveling comfort; The method that adopts is between last accelerator pedal position that once collects and current throttle pedal position, to get an intermediate value and present engine rotating speed to constitute one together jointly and quicken operating condition, in smooth operation MAP figure, searches pairing jet correct time and jet amount then.
Operating mode runs slowly; The accelerator pedal position amount of decrease surpasses 10% and regards as the acceleration operating condition; In order to keep traveling comfort; The method that adopts is between last accelerator pedal position that once collects and current throttle pedal position, to get an intermediate value and the present engine rotating speed constitutes the operating mode that runs slowly together jointly, in smooth operation MAP figure, searches pairing jet correct time and jet amount then.Surpass 40% abrupt deceleration situation for the accelerator pedal position amount of decrease, when perhaps brake pedal was operated speed-slackening signal and is activated, the strategy of taking was to stop air inlet, quickens operating condition until breaking away from, and goes to handle according to corresponding operating mode again.
Main control unit 35-4 and constitute the air flow control module from control unit 35-2.Main control unit 35-4 reads MAP data through serial ports from outside MAP data memory 35-8 according to the operating mode judgement that operating mode determination module 35-1 provides, and from the MAP data, draws needed jet correct time and jet amount.Main control unit 35-4 will send to from control unit 35-2 through serial port from jet correct time and the jet amount that MAP data memory 35-8 obtains; From control unit 35-2 utilization for example be the input parameter of engine speed and camshaft location through the conversion output drive signal, drive signal zooms into the electric signal of driving flow-controlling gate 25 unlatchings through power amplification circuit.In the exemplary embodiment, the electric signal of driving flow-controlling gate 25 is time length electric signal that valve is opened.
Compressor control module 35-5 is used for controlling additional air inlet loop according to the pressurized air state in the main storage tank 46.When the hypotony of main storage tank 46; The gas storage pressure signal 2 that promptly reflects main storage tank 46 compressed air capacity is crossed when hanging down (when for example pressure is lower than 5MPa); When compressor control module 35-5 receives this signal from data sink processing unit 35-7, can connect gate-controlled switch 4, battery cell 3 is to DC machine 6 power supplies; DC machine 6 drives and replenishes inlet air compressor 52 work, realizes the active air feed to main storage tank 46.
