Abstract
The utility model provides a front automobile collision avoidance system which comprises a central control unit, a laser distance measuring sensor, a speed measuring sensor and an automatic brake device. The laser distance measuring sensor and the speed measuring sensor are connected with the input end of the central control unit, and the automatic brake device is connected with the output end of the central control unit. The front automobile collision avoidance system uses the laser sensor to measure the distance, can find any front obstacle and is high in accuracy, wide in application and easy to popularize. After braking, the automatic brake device can trigger a flash light and a horn to give alarm to rear vehicles so as to improve driving safety. In addition, an alarm device and an accelerator locking device are further arranged to prevent an automobile from accelerating to cause danger.

Preferred as such scheme, described caution unit comprises flash light, side-marker lamp and loudspeaker.
Preferred as such scheme, described master control system is micro controller system.
Owing to have said structure, the utility model has the following advantages compared to existing technology:
1, collision avoidance system before a kind of automobile of providing of the utility model adopts laser velocimeter to make the field of application of total system more extensive, is not subjected to any limitation; Comprise dead-man's device, make chaufeur safer in motion.
2, collision avoidance system before a kind of automobile of providing of the utility model also comprises and reporting to the police and the Throttle lock locking apparatus, makes to remind chaufeur to touch on the brake when the automobile spacing is nearer, and automatically with throttle system locking, prevents that automobile from accelerating further and cause danger.
3, collision avoidance system before a kind of automobile of providing of the utility model also comprises the caution unit on the dead-man's device, is used for reminding the car of back.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structured flowchart of the preceding collision avoidance system of a kind of automobile of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of automobile preceding collision avoidance system, comprise Central Processing Unit (CPU), laser range sensor, tachogenerator, dead-man's device, described laser range sensor is connected with the input end of Central Processing Unit (CPU) with tachogenerator, and described dead-man's device is connected with the mouth of Central Processing Unit (CPU).Described Central Processing Unit (CPU) is micro controller system; Described dead-man's device comprises the caution unit, and described caution unit comprises flash light, side-marker lamp and loudspeaker; A kind of automobile front bumperette of present embodiment also comprises reports to the police and the Throttle lock locking apparatus, and described warning and Throttle lock locking apparatus link to each other with the mouth of described Central Processing Unit (CPU).
The principle of work of collision avoidance system is before a kind of automobile that this utility model provides: the place ahead that laser range sensor is contained in automobile, be used for the distance of measured automobiles and the place ahead obstacle, tachogenerator is contained on the transmission shaft of automobile, is used for the speed of measured automobiles.Send the data of measuring to micro controller system then and carry out computing.Set early warning distance and safety distance in micro controller system, speed is more fast, and early warning distance and safety distance are just more big.As when the speed of a motor vehicle of automobile during greater than 60km/h, and with the spacing of the place ahead obstacle during less than early warning distance, collision avoidance system starts before this automobile.Though if this moment spacing less than early warning distance but greater than safety distance the time, an output point of micro controller system will be exported a high level signal, triggers and reports to the police and the Throttle lock locking apparatus, and this moment, the Throttle lock locking apparatus made throttle return and locking throttle, make driving engine be in idling mode, so that car deceleration; Warning device begins to report to the police simultaneously, point out chaufeur to carry out deceleration-operation, if the chaufeur deceleration that touches on the brake this moment, when the distance of automobile and the place ahead obstacle during greater than early warning distance, this output point of micro controller system will be exported a low level signal, this moment, automobile was in a safe condition, and reported to the police and the reinstatement of Throttle lock locking apparatus automobile normal running; Chaufeur does not have any reaction if warning device is reported to the police the back, and the distance of automobile and the place ahead obstacle is less than safety distance, two output points on micro controller system this moment are exported high level signal simultaneously so, the high level signal of an output point output triggers reports to the police and the Throttle lock locking apparatus, and the high level signal of another output point output triggers dead-man's device.Warning and Throttle lock locking apparatus begin to report to the police and the Throttle lock locking apparatus makes throttle return and locking throttle, makes driving engine be in idling mode, and dead-man's device begins brake simultaneously, stops fully up to automobile.Dead-man's device also triggers the caution unit except brake, make the flash light of automobile and side-marker lamp begin flicker simultaneously, loudspeaker are rung, to remind front vehicle, two of micro controller system output point output low levels after 2 minutes, report to the police and the releasing of Throttle lock locking apparatus brake return, manual-lock flash light this moment, side-marker lamp and loudspeaker, automobile can normally travel.
Collision avoidance system before a kind of automobile that the utility model provides uses laser sensor to come measuring distance, can find any obstacle in the place ahead, and the accuracy rate height, and is applied widely, is easy to promote; Dead-man's device trigger flashing lamp and loudspeaker after brake have improved traveling security to remind front vehicle; Also be provided with in addition and report to the police and the Throttle lock locking apparatus, prevent that automobile from further accelerating and cause danger.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
