Below in conjunction with accompanying drawing the utility model patent is described in further detail.
The specific embodiment
Please refer to Fig. 1, SCM Based lane changing intelligence reminding turning device comprises some sensors 1,2,3,4......N, single chip machine controlling circuit plate 20, steering indicating light 30, reaches alarm lamp 40.Alarm lamp 40 is arranged on the gauge panel of automotive interior.Wherein some sensors 1,2,3,4......N, steering indicating light 30, and alarm lamp 40 be connected with single chip machine controlling circuit plate 20.Wherein said steering indicating light 30 and single chip machine controlling circuit plate 20 are connected by lead.
Please refer to Fig. 2, described single chip machine controlling circuit plate 20 is provided with and some sensors 1,2,3, the some first port P0.1 (AD0) of 4......N bonded assembly-P0.7 (AD7), P1.0-P1.7, P2.0-2.2.This single chip machine controlling circuit plate 20 also is provided with steering indicating light 30 and the alarm lamp 40 bonded assemblys second port P2.3-P2.5, power pin Vcc, reaches ground connection pin Vss.Use the STC12C5A60S2 micro controller system as process chip in the present embodiment, sensor from left to right number consecutively be 1～19, P0 mouth wherein, whole pins of P1 mouth and P2.0～P2.2 be 19 I/O mouths sensor 1～19 that is linked in sequence successively altogether.When certain pin wherein receives high level, the position of record pin, thus carry out analysis and judgement.P2.3～P2.5 controls the switch circuit of left and right sides steering indicating light and alarm lamp respectively.
Please refer to Fig. 3, described sensor 1,2,3,4......N respectively is provided with power pin Vcc bonded assembly first pin 11 of single chip machine controlling circuit plate 20, be connected to each the first port P1.0-P1.7, P2.0-2.2, P0.1 (AD0)-P0.7 (AD7) of single chip machine controlling circuit plate 20 second pin 12, and be connected the 3rd pin 13 of the ground connection pin Vss of single chip machine controlling circuit plate 20, wherein be provided with resistance R between first pin 11 and second pin 12.
Please refer to Fig. 4, the I/O mouth of micro controller system links to each other with the base stage of PNP aerotron C8550B, after the aerotron electric current amplifies, and the direct drive relay, opening and close fully of relay controlled by the base stage level of aerotron.When single-chip processor i/o mouth output high level, the positive-negative-positive aerotron ends, and at this moment relay is not worked; Otherwise be low level words, the conducting of positive-negative-positive aerotron, relay gets electric adhesive.
Add an earial drainage diode at coil two of relay to absorb the counter potential that produces when relay coil cuts off the power supply, prevent to disturb.AB is an open contact among the last figure, and AC is a normally closed contact, so the AB electric shock is connected in series in steering indicating light and the alarm lamp circuit.Among the figure when control signal is low level, relay normally open contact adhesive (AB conducting), when control signal was high level, relay normally open contact disconnected.For reaching the flicker of steering indicating light and alarm lamp, the utility model can be interrupted output low level with certain frequency when Single-chip Controlling I/O mouth export, reaches the purpose of delaying time 2 seconds with the timer of micro controller system.
Please refer to Fig. 5, sensor be arranged side by side on the chassis of vehicle front front end, and with sensor from left to right in order number consecutively be 1,2,3...N (N is a natural number), the distance between the adjacent sensors is less than or equal to the width of lane mark.N is 19 in the present embodiment.
When automobile did not have lane change, the sensor correspondence the road surface of black, and all the sensors output is 0 all, detects automobile and is in along lanes, does not open steering indicating light.When automobile began lane change, the sensor that captures lane mark is output signal 1 just, and record captures the numbering X of the first sensor of lane mark
1, 1≤X wherein
1≤ N, same record captures second and the 3rd sensor number X of lane mark
2And X
3, 1≤X wherein
2≤ N, wherein 1≤X
3≤ N.
Because lane mark might be detected by two adjacent sensors simultaneously, but can not be detected by the 3rd sensor simultaneously, so when the 3rd sensor is output as 1, begin to calculate X3 and X1, the magnitude relationship of X2:
If X3＞X1 and X3＞X2 then illustrate automobile lane change left, should open the left steering lamp, the micro controller system pin of then controlling the left steering lamp provides high level, control relay conducting left steering circuit for lamp, the left steering lamp is opened;
If X3＜X1 and X3＜X2 then illustrate automobile lane change to the right, should open the right steering lamp, the micro controller system pin of then controlling the right steering lamp provides high level, control relay conducting right steering circuit for lamp, the right steering lamp is opened;
Other then do not open steering indicating light.
If its X that is numbered is write down in new sensor output 1 equally
4, 1≤X wherein
4≤ N calculates it and a last number of sensor X
3Relation, if automobile continues along equidirectional lane change, then corresponding steering indicating light is still opened; If get back to former track, then steering indicating light is opposite: if X4＞X3 then opens the left steering lamp and postpones 2S; If X4＜X3 then opens the right steering lamp and postpones 2S; If X4=X3, illustrate that automobile rides line and travel, the alarm lamp that at this moment is arranged on gauge panel can glimmer, and reminds chaufeur change motoring condition; If still have sensor output just to repeat above determining step.
But the generation that the utility model tries to forestall traffic accidents when the lane change effectively by self-opening steering indicating light driver assistance person, the safety that greatly improves vehicle.What be specially adapted to that express highway gets on the car travels.
The above specific embodiment only is used to illustrate the utility model, but not is used to limit the utility model.
