Signal lights system for prompting crossed by vehicle of the present utility model, by red light light premise wake up driver slow down Stop, it is to avoid the generation of phenomenon of making a dash across the red light and vehicle accident, limit by lighting wake up driver of premise at green light Speed travels, and decreases the start-stop number of times that vehicle is unnecessary, is effectively reduced the driving intensity of driver.
Accompanying drawing explanation
Describe in detail more of the present utility model the most by way of example, and not by way of limitation Specific embodiment.Reference identical in accompanying drawing denotes same or similar parts or part.This area It is to be understood by the skilled artisans that what these accompanying drawings were not necessarily drawn to scale.In accompanying drawing:
Fig. 1 is the logic control crossing signal lights system for prompting according to the vehicle of one embodiment of this utility model Figure.
Detailed description of the invention
Fig. 1 is the logic control crossing signal lights system for prompting according to the vehicle of one embodiment of this utility model Figure, as it is shown in figure 1, signal lights system for prompting crossed by a kind of vehicle, it can include being arranged on car in general manner Image collecting device 10 at, for the image of the signal lights in collection vehicle front;Pattern recognition device 20, for the described image collected is carried out image procossing, with identify described signal lights current state and The remaining time of current state;Speed data collection device 30, for gathering the present speed of described vehicle;Radar 40, for measuring the actual range between described signal lights and described vehicle;With described pattern recognition device and The multiplier 50 that described speed data collection device signal connects, is used for obtaining described vehicle at described vehicle present speed Travel the pre-operating range of the remaining time of described current state;Connect with described multiplier and described radar signal The comparator 60 connect, for relatively described pre-operating range and described actual range;Voice prompting device 70, For reminding driver to stop or speed limit;And carry with described comparator, described pattern recognition device and voice Show the electronic control unit (ECU) 80 that device 70 signal connects, tie for the comparison according to described comparator Fruit controls the work of described voice prompting device.
By arrangement above, before green light lights, this system can effectively remind driver's speed limit in advance to avoid Unnecessary start-stop, when red light lights, this system can effectively remind driver in advance carry out parking prepare with Avoid making a dash across the red light the generation of phenomenon, substantially increase the comfort level of driving of driver.
Particularly, when driving vehicle is close to crossing, image collecting device 10 gathers belisha beacon Image, in one embodiment of this utility model, described image collecting device 10 can be photographic head, its It is arranged at the room mirror of described vehicle and towards the front of described vehicle, beacon signal is passed simultaneously Transporting to pattern recognition device 20, pattern recognition device 20 receives and processes above-mentioned information, identifies signal lights Remaining time of current state and current state, described pattern recognition device 20 can be signal processor. The current vehicle speed of speed data collection device 30 collection vehicle simultaneously, in one embodiment of this utility model, described Speed data collection device 30 is connected with the CAN of described vehicle, and gathers described from described CAN The speed data of vehicle, in another embodiment of this utility model, described speed data collection device 30 can also It is vehicle speed sensor, is arranged at vehicle motor.Additionally, radar 40 measures described signal lights with described Actual range between vehicle, in one embodiment of this utility model, described radar 40 is arranged in described At the front bumper of vehicle.
By the collection of above-mentioned each data, believe 30 with described pattern recognition device 10 and described speed data collection device Number multiplier 50 connected calculates described vehicle and travels described current state at described vehicle present speed The pre-operating range of remaining time, detailed process is: the remaining time assuming described current state is t, car Current vehicle speed be v, then t with v is multiplied and obtains vehicle and become at described signal lamp color by multiplier 50 Pre-operating range S before change, and transmit the result to comparator 60, here, obtain vehicle for convenience Current vehicle speed data, can be arranged in multiplier near described CAN.Then, with described multiplication After the comparator 60 that device 50 and described radar 40 signal connect receives pre-operating range S, by receiving Actual range between described signal lights and described vehicle that radar 40 records, here, can be by reality Distance is expressed as s, is compared with actual range s by pre-operating range S, and described comparator 60 can be One digital signal processor.In one embodiment of this utility model, it is contemplated that the width at crossing, car The actual distance that can travel should be the actual range s that radar records and deducts the width at crossing, here, The actual range s that can be recorded by radar deducts the width at crossing and is designated as s ", then by pre-operating range S and s " Compare, comparative result is transmitted to electronic control unit (ECU) 80 simultaneously.With described comparator 60 And the electronic control unit (ECU) 80 that connects of described pattern recognition device 20 signal receives and above-mentioned compares knot Really, receive the signal lights current state that described pattern recognition device 20 collects, by doing after processing simultaneously Going out corresponding control, this processing procedure, will be pre-particularly as follows: when receiving signal lights current state for time green Operating range S is compared with actual range s, if S < s, is then reminded by described voice prompting device 70 and drives Member is stopped, if S > s, is then left intact;When receiving signal lights current state for redness, will be pre- Operating range S with s " compare, if S > s ", then remind its speed limit by described voice prompting device 70, If S < s ", then it is left intact.Voice prompting device 70 can report following several voice, such as: please note Meaning is stopped;Please note speed limit;Please note maximum speed limit be 40 kilometers per hour etc..At this utility model one In individual embodiment, it is redness when receiving signal lights current state, and carries controlling voice prompting device 70 In the case of driver's speed limit of waking up, vehicle needs speed limit to much, just can avoid stopping at crossing, then may be used With by a data processor according to t with s remaining time of described current state " be calculated, as long as vehicle exists In this calculated velocity interval, driving, all can pass through crossing, it is to avoid the start-stop that vehicle is unnecessary. Here, described voice prompting device 70 can be arranged at room mirror and towards driver.
For improving alarming effect, in one embodiment of this utility model, also include and described Electronic Control list The light alarm 90 that unit's (ECU) 80 signal connects, described light alarm 90 can be arranged on described At the instrumental panel of vehicle, when it is unlocked, driver is easy for discovering, thus enhances your vigilance, Reach its effect improving alarming effect, and described voice prompting device 70 can with described light alarm 90 To be controlled to open, to improve alarming effect further by electronic control unit (ECU) 80 simultaneously.
So far, although those skilled in the art will appreciate that and the most detailed illustrate and describing the present invention's Multiple exemplary embodiments, but, without departing from the spirit and scope of the present invention, still can be according to this Disclosure of invention directly determines or derives other variations or modifications of many meeting the principle of the invention.Cause This, the scope of the present invention is it is understood that and regard as covering other variations or modifications all these.
