Summary of the invention
The purpose of this utility model is to provide a kind of cost low, the two-way caution system of a kind of lorry driving safety of easily realizing.When back has dolly to overtake other vehicles, can automatically send alerting signal by native system, prompting truck driver back has dolly to overtake other vehicles, when teamster wants to commutate passing track, system can chauffeur rearwards be passed on an alarm signal, thereby avoids the generation of accident.
For reaching above purpose, the two-way caution system of a kind of lorry driving safety that the utility model provides comprises: monitoring means, alarm unit, control unit, overtake other vehicles reminding unit and early warning display unit, it is characterized in that, described alarm unit is arranged in the visual range of chaufeur the place ahead, and the described reminding unit of overtaking other vehicles is positioned at chaufeur the place ahead scope easy to operate.
Wherein, described monitoring means comprises range finder module and two parts of speed measuring module, can measure the rear dolly with respect to the distance of lorry and relative velocity between the two by these two modules, described range finder module is laser range sensor, and described speed measuring module is radar meter.
Described early warning display unit is arranged on the tailstock, controls by chaufeur the reminding unit of overtaking other vehicles and reminds the rear dolly by the early warning display unit.
The two-way caution system of a kind of lorry driving safety that the utility model provides has following beneficial effect.
One, carry out the relative distance between this car of Real-Time Monitoring and adjacent lane dolly by laser range sensor is set in rear vehicle end, remind in time the goods vehicle driver rear to have dolly to be about to overtake other vehicles, chaufeur is taked corresponding safety measure.
Two, by the early warning display unit that is arranged on rear vehicle end, remind the dolly lorry at this car rear to be about to change, in case front vehicle attempts to overtake other vehicles simultaneously, cause accident to occur.
The accompanying drawing explanation
Figure 1 shows that the frame construction drawing of the two-way caution system of lorry driving safety that the utility model provides.
The specific embodiment
For further setting forth essence of the present utility model, below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, the two-way caution system of a kind of lorry driving safety comprises: monitoring means, alarm unit, control unit, overtake other vehicles reminding unit and early warning display unit.Wherein, described monitoring means comprises range finder module and two parts of speed measuring module, by these two modules, can measure the rear dolly with respect to the distance of lorry and relative velocity between the two; Described alarm unit is arranged in the visual range of chaufeur the place ahead, for reminding the goods vehicle driver rear, will have dolly to overtake other vehicles; The described reminding unit of overtaking other vehicles is positioned at chaufeur the place ahead scope easy to operate, and described early warning display unit is arranged on the tailstock, controls by chaufeur the reminding unit of overtaking other vehicles and reminds the rear dolly by the early warning display unit.The two-way caution system of lorry driving safety that adopts the utility model to provide, can make goods vehicle driver understand the passing behavior of rear dolly very easily, and when oneself is overtaken other vehicles rearward vehicle pass on the information reminding front vehicle of overtaking other vehicles to take care.
During real work, when lorry travels on express highway, the dolly at lorry rear is when preparing super lorry, change on adjacent passing track and prepare to accelerate and overtake other vehicles, the monitoring means of now rear vehicle end setting namely laser range sensor can real-time monitor dolly that on adjacent lane, preparation is overtaken other vehicles and the relative distance between lorry, detecting unit passes to analysis controlling unit by data, control alarm unit by analysis controlling unit and send the rear alerting signal of overtaking other vehicles to chaufeur, remind the chaufeur rear to have car to overtake other vehicles, chaufeur reminds to take corresponding safety measure according to this: when now chaufeur Ye Xianghuan travels in road, see that rear that alarm unit the sends alerting signal of overtaking other vehicles just should temporarily stop changing, continuation is travelled on former track, so just can avoid the generation of accident.
