The utility model automobile intelligent speed restrictor is to install with various automobiles, mounting structure one guiding that design has general character is subjected to force mechanisms 4 (please cooperate and consult Fig. 2), and guiding is subjected to force mechanisms 4 to comprise fixator 41, guiding Force receiver 42, fixed support 43, wire rope 44; Fixator 41 is set on any pipeline section of axle 5 the sleeve pipe 51 that is flexible coupling, and is used for fixing the position of the axle 5 that is flexible coupling, and the end of the sleeve pipe 51 of the axle 5 that is flexible coupling is fixing with guiding Force receiver 42.Guiding Force receiver 42 is fixedlyed connected with fixed support 43, and fixed support 43 is connected and fixed with car body.The other end of the steel wire 52 that wears in axle 5 the sleeve pipe 51 of being flexible coupling passes guiding Force receiver 42, is connected with fixed support 43, and these fixed support 43 bottoms connect and compose by application of force rope 44 and accelerator pedal of automobile 100.It is a position of installing to be narrowed down to have only between stress point and the center of effort that this guiding is subjected to the advantage of force mechanisms, thus reach plant oneself very little; It is the combination that is subjected to force mechanisms by be flexible coupling axle and guiding that this guiding is subjected to another advantage of force mechanisms, has realized the transfer of the direction of power easily, thereby the selection of speed restrictor installation site is increased greatly, applicable all automobiles.
GPS automobile intelligent limiter of speed is work like this: during running car, the speed probe of installing before the car speed mileometer reaches microprocessor with tach signal, also constantly that automobile is current three-dimensional coordinate signal, the direction vector of gps antenna sends the GPS module and the microprocessor of GPS automobile intelligent limiter of speed inside to, microprocessor is then constantly compared the data in current demand signal and the speed limit database, when current demand signal when data in the speed limit database conform to, pairing speed limit just becomes the current driving speed limit; When the GPS rate signal equals speed limit, the GPS automobile intelligent limiter of speed toggle speed restraint device of giving an order, control pulling force relay sends " tension " signal, speed restrictor is by the cooperation of wheel box and screw rod, produce powerful pulling force, strain the axle that is flexible coupling, throttle is pulled on, travel by setting speed; This speed restrictor forces to promote 4 to 5 centimetres by the axle that is flexible coupling to the gas pedal of automobile exactly under the control of limit switch, 10 to 15 centimetres in large-tonnage automobile, thus throttle position is limited and can't steps on, and automobile is therefore by speed limit; When the GPS rate signal was lower than speed limit, GPS automobile intelligent limiter of speed was given an order by microprocessor again and is made speed restrictor loosen throttle, and gas is recovered as before; When the gps signal conductively-closed, GPS automobile intelligent limiter of speed automatically switches into the minimum speed limit control speed of a motor vehicle, and provide rate signal by automotive speed sensor this moment, thereby allow automobile be in lower-speed state.
The utility model GPS automobile intelligent limiter of speed also is provided with the speed limit button 6 that resets (please cooperate referring to Fig. 3), when the speed limit of GPS automobile intelligent limiter of speed and road speed limit are inconsistent, the driver can set speed limit by reset button 6, the speed limit of reset button is this vehicle Maximum speed limit value, the speed limit of reset button when next speed limit is set till; If permanent haulage line is not then established reset button.
Because the speed limit database and the road restricting signal of GPS automobile intelligent limiter of speed are identical substantially, so, GPS automobile intelligent limiter of speed energy " change of road speed change ", force automobile to travel in strict accordance with road speed(-)limit sign speed limit, force automobile to travel in strict accordance with the travel route of supvr's regulation, the safety management level of automobile therefore obtains unprecedented raising.
Please cooperate referring to Fig. 3, the utility model GPS automobile intelligent limiter of speed can also comprise a voice prompting device 7, is connected with the output terminal of microprocessor.This voice prompting device has sound prompt function, prompting road speed(-)limit sign value, overspeed warning and road section information, and therefore, GPS automobile intelligent limiter of speed also can be used as GPS automobile intelligent speed limit report device and uses.
The advantage of the utility model GPS automobile intelligent speed limiting device is:
1, have function with route situation speed change and accurate speed limit:
The utility model GPS automobile intelligent speed limiting device has been broken the general layout of " speed management ", makes vapour The car safety management has been moved towards " knowledge road " management from " blind alley " management. GPS automobile intelligent speed limiting utensil has The ability of unique " initiatively knowing road and automatic speed-limiting ", accomplished easily " change of road speed change " and The requirement of " accurate speed limit ", thus the intelligent equipment that has reached the driving of present management automotive safety is The frontier.
2, have the function that departs from route pressure speed limit:
If the driver departs from travel route, GPS automobile intelligent speed limiting device can arrange the warning that departs from route Way for example, departs from 20 kilometers/hour of the above speed limits of route distance X rice, and constantly carries by handie-talkie Awake driver gets back to correct line and gets on.
3, the function that has the vector quantization speed limit:
The vector recognition function of GPS automobile intelligent speed limiting device can satisfy back and forth traffic route of up and down ramp Different speed limit requirements makes the speed limit of automobile require more to correspond to actual needs.
4, the function that has personalized speed limit:
GPS automobile intelligent speed limiting device can satisfy company to the different personnel's of different vehicle personalized speed limit pipe Reason needs, and reaches the purpose of aimed management by parameters. For example, the car that has can be walked three lines A route can only be walked in road, the car that has; 100 kilometers/hour of the car Maximum speed limits that has, the highest limit of car that has Fast 80 kilometers/hour etc.
5, the function that has mandatory administration:
GPS automobile intelligent speed limiting device can force the driver to accept the speed management system of company, if the driver Hide gps antenna with metallic shield, make the GPS car-mounted terminal can not receiving satellite signal, so, GPS The automobile intelligent speed limiting device will be put automobile with minimum speed limit state, thus the thought that makes the driver abandon exceeding the speed limit.
6, have the travel route track playback function:
Different from other GPS vehicle tracking device is, because the effect of limiter of speed, the driver can't be with golden Thereby belong to radome and hide the writing function inefficacy that satellite antenna makes GPS automobile intelligent speed limiting device. Work as GPS When the automobile intelligent speed limiting device does not receive satellite-signal, the driving trace that it transmits the writing speed sensor, Thereby reproduce the driving process of automobile, thereby provide solid foundation for fine-grained management.
The utlity model has far-reaching promotion prospect, if the road traffic speed-limiting messages in the whole nation is all imported In the database of GPS automobile intelligent speed limiting device, so, as long as GPS automobile intelligent speed limiting device has been installed, Automobile has just possessed the function of " knowing road and overspeed prompting " and the function of " knowing the road speed limit ", can limit Automobile particularly forces automobile to run at a low speed in the different speed of different road goings in the hazardous location, Thereby greatly reduce the generation of traffic accident.
