Forced speed-reducing safety device for vehicles provided by the invention, owing to comprise the throttle automatic control device, according to the instruction unpack of control module/close oil circuit control voltage, control of fuel supply is being kept idle oil mass, make the speed of a motor vehicle be reduced to automatically speed limit 90% after, recover the mode of operation of normal fuel injection again, thereby played the effect of forcing reduction of speed; This device can be carried out monitoring in real time to vehicle, in case the hypervelocity behavior takes place, then can carry out record at once, simultaneously, in the enforceable speed range that the speed of a motor vehicle is dropped to safety traffic, effectively, initiatively, forcibly prevent the hypervelocity behavior, eliminate hidden peril of accident, safety is good, application value is very big.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a systematic schematic diagram of the present invention;
Fig. 2 is the fundamental diagram of control module of the present invention;
Fig. 3 is the External view of control module of the present invention.
The specific embodiment
As shown in figures 1 and 3, the present invention includes:
Throttle automatic regulating device 3 is used for the control vehicle throttle;
In the described data acquisition module 1, vehicle speed signal collector 5 connects frequency divider 6 in real time, and frequency divider 6 is connected with control module 2.Vehicle speed signal collector 5 is from the real-time speed of a motor vehicle of vehicle autometer collection in real time.
Described control module 2 is a micro controller system, which is provided with a plurality of port ones 3, is used for the reception and the transmission of data.
In the described throttle automatic regulating device 3, relay 7 link control modules 2 are according to the instruction unpack of control module 2/close oil circuit control circuit.
Be connected with warning indicator lamp 11 on the described relay 7
In the described data outputting module 4, the outer speed limit telltale 8 of car, hypervelocity speed of a motor vehicle logger 9 are connected with control module 2 respectively with annunciator 10.The outer speed limit telltale 8 of car adopts luminous digital diode to show the set speed limit of vehicle, with supervision and the inspection that makes things convenient for supervisory management zone, can prevent that also navigating mate from destroying the cheating of this device; But the time and the speed of hypervelocity speed of a motor vehicle logger 9 instant recordings hypervelocity are in order to investigation, the evidence obtaining of traffic police department; Be with speech chip in the annunciator 10, can store prompting/alarm voice of prerecording, and play cooresponding prompting/alarm voice according to the instruction of micro controller system;
Under the situation of overspeed of vehicle,, will carry out the action that sound/light is reported to the police and embarkation lamp light is reported to the police in the car if navigating mate is not taked the deceleration measure in 35 seconds.
Principle of work of the present invention is as follows:
As shown in Figure 2, this device at first receives the restricting signal that is transmitted by satellite navigation system by the corresponding port on the control module 2 (micro controller system) 13, micro controller system receives behind this signal that speed limit telltale 8 sends instruction outside car, promptly shows the speed limit of this road on the read-out of the outer speed limit telltale 8 of car; The real-time vehicle speed signal that real-time vehicle speed signal collector 5 also will collect is sent in the control module 2 (micro controller system) by corresponding port 13 behind frequency divider 6 frequency divisions.
Micro controller system is after receiving restricting signal and real-time vehicle speed signal, and meeting compares both values immediately, if exceed the speed limit, then can not send any instruction, normal vehicle operation; If hypervelocity, micro controller system then sends instruction to relay 7, closes the oil circuit control circuit, make throttle voltage drop to " 0 " volt, keep idling speed fuel delivery, forcibly the speed of a motor vehicle is reduced to 90% of speed limit, also can connect with relay 7 bonded assembly warning indicator lamps 11, play the effect of caution; Simultaneously, send instruction by 13 pairs of hypervelocities of corresponding port speed of a motor vehicle logger 9, hypervelocity speed of a motor vehicle logger 9 can be noted the time and the speed of hypervelocity, and annunciator 10 also can carry out sound/light actuation of an alarm according to the instruction of micro controller system.
When the speed of a motor vehicle be reduced to speed limit 90% after, micro controller system sends instruction quits work relay 7, the oil circuit control circuit is opened, navigating mate recovers the control to the throttle oil mass.Simultaneously, annunciator 10 quits work.
The treatment principle of 2 pairs of speed limits of control module is as follows:
1, according to " freeway management regulations " " chapter 4; forbid pedestrian, unpowered vehicle, trac., storage battery car, agriculture truck, wheeled special-purpose machinery, full ailer-towing vehicle and design the self-propelled vehicle that maximum speed per hour is lower than 70 kilometers for the 17 entering express highway; but carry out except the personnel of freeway management task and maintenance work and machinery, the vehicle " regulation, this device is designed to: all speed limits are higher than 70 kilometers, handle by Speed Limitation on Freeway regulation and way; Be lower than 70 kilometers, handle by ordinary road speed limit regulation and way.At the vehicle of running on expressway, under the premise that security is guaranteed, allow 10% of hypervelocity speed limit, but the highlyest must not surpass 20%.The vehicle that travels on ordinary road only allows to travel in the speed range that limits, and allows any hypervelocity behavior anything but.
2, express highway
(1), do not punish management method, when the speed of a motor vehicle exceeds the speed limit 10% the time, the red alarm lamp glimmers slowly in the car, reminds navigating mate to exceed the speed limit now, should take the deceleration measure according to the overspeed of vehicle 10% of existing running on expressway.When the speed of a motor vehicle exceeds the speed limit 20% the time, the inside and outside red alarm lamp fast blink of car, alarm sound acutely sounds (in order not influence other normal vehicle operation in the car, the outer alarm free sound of car), and remind navigating mate, the speed of a motor vehicle surpasses the moving velocity of regulation now, abnormally dangerous, should take the deceleration measure immediately.
(2), when red alarm lamp fast blink 3-5 second, if vehicle also keeps the state of driving over the speed limit, control module 2 is sent instruction, the oil supply system for vehicle delivery quality progressively is decreased to idling speed fuel delivery automatically, the speed of a motor vehicle begins progressively to reduce automatically, speed of a motor vehicle reduction this moment reason is the minimizing of delivery quality, but not brake reason, to guarantee the safety of driving, brake taillight lights, can remind the back vehicle to notice that this car is slowing down, prevent the generation of knocking into the back, brake taillight is bright to be extinguished to the deceleration system SELF CL again.Chaufeur can be trampled brake and manually braked simultaneously this moment.When the speed of a motor vehicle drop to set limited speed 90% the time, fuel-feeds system etc. recover normal working.
3, ordinary road
As long as exceed the speed limit, red alarm lamp fast blink 3-5 second also keep the state of driving over the speed limit as if vehicle,
