Abstract

The utility model discloses a warning system for automobile travel state, comprising a throttling valve position sensor 1, a speed sensor 2, a braking power degree sensor 3, a center data processor 6 and blue and red lamp groups 89. To foreshow the changing situations of highway condition ahead, the apparatus adopts that the blue and red lamp groups 89 at automobile tail through a show driving 7 connect the throttling valve position sensor 1, the speed sensor 2, the F/V changing apparatus 4 and the center data processor 6 in series, and the braking power degree sensor 3, a P/V converter 5 and the center data processor 6 in series, with the center data processor 6 in parallel. The utility model has simple structure and low cost and is reliable and stable.

Description

Running car situation caution system

Technical field

The utility model relates to a kind of alarming device, particularly a kind of running car situation caution system that can indicate the place ahead road conditions.

Background technology

At present along with the improving constantly of living standard, automobile more and more becomes the irreplaceable vehicle in the people's lives, but incident traffic accident also significantly increases.Be because the Changes in weather or the speed of a motor vehicle are too fast on the one hand, it mainly is because front truck can not in time be warned the problem of back vehicle front roadblock, so that can not adopt an effective measure under panic traffic accident takes place.Though the Warning light of present invention is of a great variety, be nothing but on stoplight stop lamp, to operate, can't make back car differentiate the actual at that time road conditions in the place ahead, easily cause the front vehicle error in judgement, casualty accident takes place.

Summary of the invention

The purpose of this utility model is to provide glittering degree and the quantity running car situation caution system of in time warning back vehicle front road conditions of a kind of energy by Warning light.

The purpose of this utility model is achieved in that a kind of running car situation caution system, mainly form by throttle position sensor, car speed sensor, braking strength sensor, central data processor and red, blue display unit, it is characterized in that: red, blue display unit is controlled by throttle position sensor and braking strength sensor respectively, and wherein red, blue display unit is to be made of two groups of display drivers and lamp group.When throttle position sensor changed, the acceleration/accel of self-propelled vehicle also changed thereupon, and one group of blue look display unit lamp changes thereupon in the motor vehicle tail display unit, and acceleration/accel increases, and the quantity of taillight can increase; And when the braking strength sensor began to change, another group red display unit lamp changed thereupon in the motor vehicle tail display unit, and braking strength is big, and the bright lamp quantity of taillight can increase.From the bright number of lamp of the display unit of automobile tail what, can indicate the trend that the place ahead road conditions change, thereby reach the purpose of prediction.

Because the utility model not only adopts the bright number of lamp of the dual Control of Automobile afterbody of the speed of a motor vehicle and brake to remind driver behind the car to keep a safe distance, reduce the traffic accident of vehicle collision, and simple in structure, cost is low, working stability is reliable.

Be described further below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure 1, throttle position sensor 2, car speed sensor 3, braking strength sensor 4, F/V changer 5, P/V conv 6, central data processor 7, display driver 8, blue look display unit 9, red display unit

The specific embodiment

In the drawings, the throttle position sensor (1) that is installed on the air throttle of car is a variable rheostat, the acceleration magnitude in its aperture size indication motor-driven vehicle going process; And car speed sensor (2) is an on-off signal, comes from the mouth of automobile kilometer sensor, and its signal is given the central data processor voltage signal that (6) rules change through the processing of F/V changer (4); Braking strength sensor (3) is mounted on the output oil pipe of automobile brake general pump, the oil pipe internal pressure change to be what the size variation with brake weight changed, this signal is given the voltage signal of (6) rules of central data processor through the conversion of P/V conv (5); P/V conv (5) is real to be a threshold level.After vehicle speed signal is handled through F/V changer (4), when exporting a high and low level along with the variation of vehicle speed signal, by the acceleration control system that throttle position sensor (1), car speed sensor (2), F/V changer (4), central data processor (6), display driver (7) and blue look display unit (8) are formed jointly, its display driver (7) is gone up meeting obtains a respective change with the size of the aperture of throttle position sensor (1) voltage signal.Throttle position sensor (1) aperture gradually hour, the indication pickup slows down, display driver (7) output at this moment is low level, blue look display unit (8) is gone up the bright number of lamp can be few, become gradually greatly as throttle position sensor (1) aperture, the indication automobile quickens, the blue look display unit (8) of automobile tail is gone up the bright number of lamp and can be increased; The last bright number of lamp of blue look display unit (8) changes with the aperture of throttle position sensor (1); Blue look display unit (8) is available green also.When the complete closing automobile tickover of the aperture of throttle position sensor (1), red display unit (9) have light flash.When running into emergency case in the vehicle ' process and need brake, form brake control system by braking strength sensor (3), P/V conv (5), central data processor (6), display driver (7) and red display unit (9), can be along with the pressure signal size variation of braking strength sensor (3), the bright several respective change of lamp are gone up in the red display unit (9) of automobile tail, it is many that the pressure signal of braking strength sensor (3) is big, red display unit (9) go up the bright number of lamp, otherwise still.Braking strength is directly proportional with the frequency of flicker.The also available radar beacon in red display unit (9).

Claims

1, a kind of running car situation caution system, mainly 1. by throttle position sensor, car speed sensor 2., the braking strength sensor 3., central data processor 6., 7. and blue display driver, 8. and 9. the red display unit is formed, and it is characterized in that: orchid, 7. with throttle position sensor 1. 8. and 9. the red display unit pass through display driver respectively, car speed sensor 2., the F/V changer 4., central data processor 6. be connected in series the back and the braking strength sensor 3., the P/V conv 5., be parallel to after 6. central data processor is connected in series that 6. central data processor go up.

2, running car situation caution system according to claim 1 is characterized in that: 8. and 9. blue, red display unit is made of two groups of lamp groups respectively.
