Further, described first camera and second camera are arranged on the right and left on front window top respectively, and with respect to the horizontal plane downward-sloping 3 ~ 5 degree, adopt binocular imaging principle to detect road surface ahead and whether have obstacle or depression, the information detected is sent to image processing module by two cameras, and image processing module sends to master controller after treatment.
The control method of described control system is as follows:
1) start cruise state by cruise control switch, setting cruising speed, cruising speed is 30 ~ 120km/h, and the information detected is sent to primary controller by the running state of all detections of radar surrounding vehicles on car;
2) if Foregut fermenters detections of radar does not have to our vehicle traveling lane front, then primary controller controls our vehicle and at the uniform velocity travels according to the speed of setting; If Foregut fermenters detections of radar has vehicle to our vehicle traveling lane front, and the moving velocity of this vehicle is less than the moving velocity of our vehicle, then primary controller controls our car retardation, guarantees to reach safe stopping distance between this vehicle, then adopts the mode of following to travel; If front vehicles generation lane change, or our vehicle lane change, make our vehicle front not have vehicle to travel, then primary controller controls our vehicle and carries out accelerating until at the uniform velocity travel after reaching the speed of setting;
Accelerate in the process of setting speed traveling above-mentioned, primary controller will by left side detect radar and right side detect detections of radar to both sides vehicle condition judge whether we should accelerate by vehicle immediately, if detect, the speed of left and right sides vehicle and acceleration/accel are all less than our vehicle, then now our vehicle can accelerate, otherwise can not accelerate; Meanwhile, the distance of both sides vehicle apart from our vehicle is also noted that; When radar is detected in left side and right side detection detections of radar is less than 0.5m to left side or right side distance, then can not accelerate, and control voice driven module controls loudspeaker are sent information of voice prompt by primary controller;
3) if rear car detects radar, detect that the safety distance of front vehicle is less than the safe stopping distance of its present speed, control voice driven module controls loudspeaker are sent information of voice prompt by primary controller;
4), the first camera and second camera gather the information on road surface, by the information detected by sending to primary controller after image processing module process, when detecting that the height of road obstacle is when being less than 10cm, car retardation, to 30km/h, accelerates to setting speed after breaking the barriers again; When detecting that the height of obstacle is greater than 10cm, car retardation is to 30km/h, and primary controller controls voice driven module controls loudspeaker and sends voice message;
When detecting that the pit area on road surface is less than 0.5m
2, when the degree of depth is less than 5cm, car retardation to 30km/h, by accelerating to setting speed again after pit, when detecting that the pit area on road surface is greater than 0.5m
2, when the degree of depth is greater than 5cm, car retardation is to 30km/h, and primary controller controls voice driven module controls loudspeaker and sends voice message;
5), weather detection module, judge whether that rainy and greasy weather visbility is to adjust the speed of a motor vehicle and safe stopping distance;
6), tire pressure mal time, exit cruising condition, display alarm information on read-out;
7), when primary controller receives failure message, cruising condition is exited, display screen display failure message;
8), when starting cruise mode and exit cruise mode, control voice driven module controls loudspeaker are all sent information of voice prompt by primary controller.
Further, in described control method (2), (3), (4), the relation of safety distance and speed adopts following formula to calculate:
S=v2/2gμ+50
In formula, S is safe stopping distance, and unit is m; V is speed, and unit is m/s; G=9.8m/s
2; μ=0.8;
The span of automatic cruising speed is 30 ~ 120km/h, then safe stopping distance is 54 ~ 121m.
Further, when weather detection module detects rainfall, safe stopping distance must be worth increase by 15% by primary controller automatically, when weather detection module detects that greasy weather visbility is between 100 ~ 200, automatic will cruise to test the speed be limited in below 60km/h, brake safe distance increase by 40%; When weather detection module detects that greasy weather visbility is between 50 ~ 100m, will cruise to test the speed automatically is limited in below 40km/h, and brake safe distance increases by 40%; When weather detection module detect greasy weather visbility between 100 ~ 200m and rainy time, automatic will cruise to test the speed be limited in below 50km/h, brake safe distance increases by 45%, when weather detection module detect greasy weather visbility between 50 ~ 100m and rainy time, automatic will cruise to test the speed be limited in below 30km/h, brake safe distance increase by 45%.
Further, when the pressure that tie pressure detection module detects tire is not when 2.3 ~ 2.5kpa is within the scope of this, automobile will exit cruising condition automatically, and shows the not enough information of corresponding tire pressure by read-out.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
