Briefly, a kind of anti-recoil control system that is used for motorcycle comprises the target wheel that is installed in the segmentation on the engine crankshaft.Sensor element on the motor is inquired the rotating speed of motorcycle engine on a plurality of predetermined angle intervals before the TDC.If satisfy minimum rotational speed criteria at interval, be embedded in the logic in the control system or change precalculated timing, or end spark ignition, with the counter-rotating that prevents motor and the recoil of starting pedal at preset time.
Brief description
By example the present invention is described now with reference to accompanying drawing, wherein:
Fig. 1 is that schematic representation is installed in the target wheel on the engine crankshaft, and it has shown the sensor that is used to inquire crank position;
Fig. 2 is the sketch of the use of positive hour wheel shown in the displayed map 1 and sensor; And
Fig. 3 is a flow chart, and it has shown according to of the present invention and is used to prevent the method that recoils.
Preferred embodiment is described
Referring to Fig. 1, the bent axle 10 of the motor 12 on the motorcycle 13 is provided with target wheel 14, and it is fixedly mounted on the bent axle 10, so that with rotation therewith.The treadle 11 that provides is used for impelling crankshaft rotating at originate mode.Target wheel 14 comprises a plurality of advance/retard mechanisms of opening by angle intervals, for example, the tooth 16 that is provided with along target wheel periphery 18, it is used to provide the alternating signal from crank sensor 17.Can adopt any form that oneself knows according to advance/retard mechanism of the present invention, it is used to produce the signal of indication bent axle 10 angular orientation at any time, for example, and magnetic domain on the hole in the target wheel, the target wheel or the like.
In the currently preferred embodiments that are used for preventing the bent axle recoil, target wheel 14 is provided with 23 teeth 16, and it is spaced apart with 15 ° of angle intervals, causes having about 30 ° gap 20 between tooth 23 and tooth 1 (that is, lacking tooth 24).Thereby the gap between tooth 23 and 1 doubles other gap 22 basically, and thereby provides the convenient mark of being convenient to controller 50 identification tooth 1 when each rotation.The present invention comprises tooth and its spacing of other number fully.Crank sensor 17 be positioned at tooth 16 rotate path near, be used to produce the signal 19 of the angular orientation of indication target wheel 14 and bent axle 10, and signal 19 sent to engine controller 50.In this way, can accurately determine between two concrete teeth, for example between tooth 3 and the tooth 4, between tooth 6 and the tooth 7 and the rotational time between tooth 8 and the tooth 9.
Referring to Fig. 1 and Fig. 2, in the act example, tooth 9 places at random are located in the top dead center of the piston in the motor 12 (TDC) position.In order to prevent recoil,, can at random plug ignition will be used for so that the ignition location 24 of starting is located at afterwards 5 ° of TDC (ATDC) by guarantee that taking precautions against spark plug lighted a fire before TDC.DT 26 is under the 1200rpm rotating speed for dwell length (dwell length), is assumed to 3 milliseconds.In traditional ignition system, this is equivalent to breaker contact point and disconnects, and allows in time cycle that the primary side of spark coil is set up magnetic field.As oneself knows in related domain, when resident (dwell) end cycle, breaker points close, magnetic field is disintegrated, and produces induction current in the primary side of coil, so that plug ignition.
Referring to Fig. 3, shown in the exemplary arrangement of 23 teeth, wherein tooth 9 is positioned at the TDC place, and tooth 4 (BTDC) 75 ° before TDC locates, during pedal foot pedal starting motor 12, preferably move with following three independent sequence-level according to igniting logic system 100 of the present invention:
Sequence 1:Measure the rotational time between tooth 3 and the tooth 4, shown in tooth among Fig. 2-tooth time X.
If X is greater than predetermined calibration value, engine speed is then too low, and may cause recoil, thereby makes spark start delay a period of time of plan, and proceeds to sequence 2, is determined by the look-up table (not shown) that is embedded in the engine controller 50 during this period of time.
If X is less than or equal to predetermined calibration value, motor then rotates enough soon, to guarantee spark ignition after TDC.By calculate " the spark edge number of teeth " (SETN) and " the resident edge number of teeth " (DETN) can calculate the standard ignition timing that is used for turning crankshaft, the spark edge tooth is the tooth of plug ignition when beginning, the tooth when resident edge teeth is resident 28 beginnings.
SETN=(ATDC+BTDC)/15+4=(5+75)/15+4=9.33 (equation 1)
DETN=9.33-(3/ (60000/1200) * 360)/15=7.89 (equation 2)
Utilize total number of teeth of nearest front, spark edge is calculated tooth be distributed on the tooth 9, resident edge calculations tooth is distributed on the tooth 7, and proceeds to sequence 2.
Sequence 2:The time of measurement between tooth 6 and tooth 7, shown in the tooth among Fig. 2-tooth time Y, it is restricted to " dwell tooth time " DTT here.
If Y is greater than predetermined calibration value, engine speed is then too low, and may cause recoil, thereby can not be provided with residently, and ends the charging of the primary side of spark coil.Owing to locate and not have spark 5 ° of ATDC specified points,, also can not start so motor will can not recoil.
If Y is less than or equal to predetermined value, motor will rotate enough soon, thereby will light a fire.Can find out that from the result of equation 2 resident (dwell) cycle begins enough early, so that the spark coil charging (in example, 0.89 millisecond of toothed portion after the tooth 7,0.89 millisecond of toothed portion=0.89*DTT wherein, the resident edge 28 among-Fig. 2).Must carry out spark ignition now.
Proceed to sequence 3.
Sequence 3:After the resident cycle 26 has begun, measure the time between tooth 8 and tooth 9, shown in the tooth among Fig. 2-tooth time Z, it is restricted to " spark tooth time " STT here.
If Z is less than or equal to predetermined calibration value, motor will rotate enough soon, thereby will light a fire on the time of calculating.From equation 1, can find out, the spark edge in the example shown is made as tooth 9 0.33 millisecond of toothed portion (tooth fraction in miliseconds), wherein 0.33 millisecond of toothed portion=0.33*STT (ignition location 24 among Fig. 2) afterwards.
If Z is greater than predetermined calibration value, engine speed is then too low, and may cause recoil.Make the spark timing retard, and make the predetermined angular metric of demarcating of resident cycle stretch-out, it is proportional with time Z, occurs in after the TDC to guarantee igniting, thereby prevents to recoil.
Can allow igniting in no instance, sense tooth 9 (TDC) until.
When motor 12 igniting, and the rotating speed of target wheel 14 is when surpassing predetermined value, and anti-backpurge system 100 is inoperative, and engine ignition control recovers normal mode of operation.
Though, should understand, in the essence of described novel concept and scope, can carry out many variations by having described the present invention with reference to various certain embodiments.Therefore, the present invention is not limited to described embodiment, but will have the full breadth that is limited by following claim.
