The further improvement of the utility model is, is parallel with the auxiliary braking pipeline from the main brake pipeline of the brake system of car, and the auxiliary braking pipeline is provided with control cock, and the control end of control cock is electrically connected a delivery channel of said micro controller system; It further improves and is, said control cock is an electromagnetic valve.
In the utility model; For front truck, utilize radar before the car, be used to gather front truck with from the relative distance of car, the speed of a motor vehicle and relative angle relatively; Micro controller system gather in real time front truck with from the relative distance of car, the speed of a motor vehicle and relative angle relatively; Judge whether and to send from the car alarm to buzzer phone,, realize initiatively braking through control cock and auxiliary braking pipeline perhaps according to dangerous situation; For the back car, utilize radar behind the car, gather in real time the back car with from the relative distance of car, the speed of a motor vehicle and relative angle relatively, and judge whether and need back car alarm be provided to read-out.The utility model adopts early warning, initiatively brakes the mode that combines, and can reduce the generation of vehicle rear-end collision accident.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
Fig. 1 is the principle schematic of the anti-device that knocks into the back of this practical a kind of vehicle.
The specific embodiment
With reference to Fig. 1, for the anti-device that knocks into the back of this practical a kind of vehicle, comprise micro controller system, respectively with car that micro controller system is electrically connected before radar, buzzer phone, read-out behind the radar, car.Wherein, radar before the car is installed on from car anteriorly, and its signal wire (SW) is connected with the first input channel PM1 of micro controller system, is used to gather front truck and from the relative distance of car, the relative speed of a motor vehicle and relative angle; Radar behind the car is installed on from the car rear portion, and its signal wire (SW) is connected with the second input channel PM2 of micro controller system, be used to gather the back car with from the relative distance of car, the speed of a motor vehicle and relative angle relatively; Buzzer phone is installed in the car operator's compartment, and its signal wire (SW) is connected with the first delivery channel PB1 of micro controller system, is used for from the car alarm; Read-out is installed on from the car tailstock, and its signal wire (SW) is connected with the second delivery channel PB2 of micro controller system, is used for back car alarm; Main brake pipeline from the brake system of car is parallel with the auxiliary braking pipeline, and the auxiliary braking pipeline is provided with control cock, and the 3rd delivery channel PB3 that the control end of control cock is electrically connected micro controller system connects, and concrete control cock is an electromagnetic valve.
In the present embodiment, micro controller system adopts Freescale S12 model micro controller system.Radar all adopts Delphi ESR millimeter wave radar behind preceding radar of car and the car, is installed in bumper/spoiler top, vehicle front and back centre respectively.With respect to microwave radar, it has the advantage that volume is little, in light weight, velocity of wave is narrow, bandwidth is big, antijamming capability is strong, simultaneously, also has climate adaptability preferably.
During use, micro controller system is gathered front truck in real time and from the relative distance of car, the relative speed of a motor vehicle and relative angle, is judged whether and need send from the car alarm to buzzer phone; Gather in real time the back car with from the relative distance of car, the speed of a motor vehicle and relative angle relatively, judging whether to provide back car alarm to read-out.If the nearest front truck in this place ahead, track with from the distance of car less than safety distance 4m; And the relative velocity of two cars is for negative, promptly two cars constantly near, the Single-chip Controlling buzzer phone sounds the alarm; Prompting is noted spacing from the car chaufeur; Open electromagnetic valve simultaneously, make car brakeing slow down or parking, avoid the generation of rear-end collision; When two spacings during greater than 4m, buzzer phone quits work, and simultaneously, closed electromagnetic valve stops braking.If the nearest back car in this rear, track with from the distance of car less than safety distance 4m, and the relative velocity of two cars is being for just, promptly two cars near, Single-chip Controlling read-out display reminding literal, remind afterwards the car chaufeur to note spacing constantly, avoid knocking into the back; When two spacings during greater than 4m, read-out quits work.
Although more than combine accompanying drawing that the embodiment of the utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification sheets, these all belong to the row of the present invention's protection.
