The control of air car is undertaken by the operation of control setup 35 according to the operating mode of air car and chaufeur.As depicted in figs. 1 and 2, control setup has multiple input, such as accelerator pedal position signal 38, engine rotational speed signal 36, key switch signal 37, vehicle speed signal, main reservoir pressure signal 2, heating tank internal pressure signal 39, decompression tank internal pressure signal 41, the temperature signal 34 measured by the temperature sensor 18 be arranged on heating controller 17, speed-slackening signal and be such as other inputs of ambient-air temperature, intake pressure.After control setup 35 processes, the control command 33 of control flow check control valve 25 is sent after multiple incoming signal input control device 35, thus the opening and closing of control flow check control valve 25.
The concrete structure of control setup 35 as shown in Figure 2.Control setup 35 comprise data reception processing unit 35-7, operating mode determination module 35-1, main control unit 35-4, from control unit 35-2, power amplification circuit 35-6 and MAP data memory 35-8.Main control unit 35-4 and form air flow control module 35-0 from control unit 35-2.Control setup also comprises the heating control module 35-3 controlling heating controller 17 and operate, and controls through gate-controlled switch 4 the compressor control module 35-5 supplementing inlet air compressor 52.Preferably, control setup 35 also comprises exception handling module 35-9, to start purpose overspeed protective module 35-10 according to the operating mode of vehicle or to shut down the action of module 35-11.The working process of control setup 35 will be described in detail below.
Data reception processing unit 35-7 receives accelerator pedal position signal 38, engine rotational speed signal 36, key switch signal 37, vehicle speed signal, gas tank air pressure signal (2,39,41), temperature signal 34 and other incoming signals, these signals, after data reception processing unit 35-7 treatment and analysis, are sent to operating mode determination module 35-1.Operating mode determination module 35-1 judges the operating mode of vehicle according to the input of data reception processing unit 35-7.In an exemplary embodiment of the present invention, the air-powered motor 31 control setup 35 controlled operating mode is divided into starting duty, idling operation, steady state operating condition, Accelerating running operating mode, run slowly operating mode.Control setup 35 takes different air inlet strategies according to different operating modes.
Starting duty, when key switch signal 37 is enabled, when engine rotational speed signal 36 is less than idling speed threshold signal, namely thinks that air-powered motor 31 is in starting duty.Now, vacuum pump 13 is opened, the pressurized air of certain pressure enters decompression storage tank 5 from main storage tank 46.For the ease of the starting of air-powered motor 31, adopt to look into and get having little significance of MAP, now, fixing jet timing and jet amount is adopted (during top dead point, to start air inlet, and adopt maximum jet amount, so that start), by the adjustment of rotational speed of driving engine to idling, then with the jet timing of idling and jet amount, the rotating speed of air-powered motor 31 is maintained in idling, to wait for next step operation.The different idling threshold value of adjustment can be set according to different air-powered motors 31.Because air-powered motor is generally wool(l)y-type engine, idling threshold value can be set as 300 revs/min or 500 revs/min.
Idling operation, when throttle position is 0%, when engine speed is higher than idling threshold value, is defined as idling operation.The size of idling speed is according to looking into the practical operation situation of getting MAP data under this operating mode and determining.
Steady state operating condition, namely driving engine operates under accelerator pedal position and load immobilize or change less condition, and the rotating speed of driving engine can keep constant.In order to simplify the control of driving engine, the situation that accelerator pedal position change can be no more than 10% is defined as steady state operating condition.In outside MAP data memory 35-8, store the MAP of steady-state operation, according to engine speed and accelerator pedal position, directly search and call corresponding jet amount and jet timing.
Accelerating running operating mode, accelerator pedal position amplification regards as Accelerating running operating mode more than 10%, in order to keep traveling comfort, the method adopted gets an intermediate value between the upper accelerator pedal position that once collects and current throttle pedal position, cooperatively form an Accelerating running operating mode with present engine rotating speed, then in smooth operation MAP, search corresponding jet timing and jet amount.
Run slowly operating mode, accelerator pedal position amount of decrease regards as Accelerating running operating mode more than 10%, in order to keep traveling comfort, the method adopted gets an intermediate value between the upper accelerator pedal position that once collects and current throttle pedal position, cooperatively form the operating mode that runs slowly with present engine rotating speed, then in smooth operation MAP, search corresponding jet timing and jet amount.For the abrupt deceleration situation of accelerator pedal position amount of decrease more than 40%, or brake pedal is operated speed-slackening signal when being activated, and the strategy taked stops air inlet, until depart from Accelerating running operating mode, then goes process according to corresponding operating mode.
