Description
[technical field]:
The utility model relates to a kind of Vehicular indicating.
[background technology]:
At present, along with progressively popularizing of automobile, it is outstanding that the driving safety problem more shows, so some automobile-used auxiliary devices occurred, attempt the safety from all angles raising vehicle ', as being in 01110158 the Chinese patent application at application number, disclosed a kind of dynamic speed read out instrument that is used for automobile; It is made of far viewing dynamic vehicle speed indication lamp, shaping amplifier, sensor, ratchet.The speed of a motor vehicle is high more, it is high more that sensor produces electrical impulse frequency, shaping amplifier output direct ratio voltage is just high more, and it is just many more that far viewing dynamic vehicle speed indication lamp is laterally lighted, and can allow every chaufeur see the moving velocity of the front truck that far viewing dynamic vehicle speed indication lamp is shown in real time, intuitively.But there is following shortcoming in this technical scheme:
1, " far viewing dynamic vehicle speed indication lamp " indicator lamp that system adopted is to be made of 5～200 luminous elements of a row, and this luminous element or served as by LED is perhaps served as by osram lamp.This design only can the display automobile running velocity absolute value (promptly in a single day speed arranged when vehicle, just there are some luminous elements luminous), and concrete speed is in increase or is reducing, need chaufeur on the car of back to remember the total length of all luminous elements of previous moment, and the total length of it and all luminous elements of present moment is made comparisons to make judgement; Attention and memory to the back vehicle driver are had relatively high expectations.Under the situation of high vehicle speeds, can disperse the attention of back chaufeur on the contrary, if the distance of front and back two cars is shorter, less velocity variations also can cause the accident.When the velocity amplitude of setting unit luminous element representative was identical, at the vehicle that the different vehicle maximum speed is arranged, thereby not only the quantity of luminous element will be subjected to the suitable vehicle scope of the restriction limits product of width over sides of car body; And the luminous element quantity of using in the specific product of this indicator lamp system also will change, and causes this product not possess commonality.If join various vehicles with the indicator lamp of same model, the velocity amplitude difference that unit luminous element representative can occur, might also not reflect variation by indicator lamp when speed changes to some extent, cause erroneous judgement for easily the back chaufeur, hidden danger all the better easily causes the accident.
What 2, next this technical scheme was expressed is the velocity amplitude of vehicle at each quarter, this there is no need in real-world operation, because the back chaufeur can estimate the speed of front vehicles by the speed meter of vehicle own, and our major concern is the situation of change of front vehicles speed, correctly in time to make the judgement that whether can overtake other vehicles or need to slow down, improved active safety." far viewing dynamic vehicle speed indication lamp " of this application failed the effective expression travel condition of vehicle, such as vehicle (do not step under the braking situation, comprise adding, subtracting throttle, slide etc.) when quickening or slow down, and these states produce a very large impact the operation of back vehicle.For example front vehicles is when quickening, and pursuit-type vehicle does not allow to overtake other vehicles in principle, if but do not have this state demonstration, pursuit-type vehicle just possibly can't judge correctly whether front truck quickens, and causes easily blindly and overtakes other vehicles, and increases accident potential.Therefore must indicate these states,, observe the motoring condition of front truck intuitively, judge the operation conditions of front truck fast, accomplish that precautions averts perils, strengthen the active safety of back vehicle driving so that the pursuit-type vehicle chaufeur when driving.This point is this application open question exactly.
