Description
Technical field
The safety device of a kind of vehicle of the utility model particularly a kind ofly is applicable to the throttle emergency brake arrangement during misoperation accelerator pedal in when brake.
Background technology
Chaufeur is in the vehicular drive process, and particularly the beginner is in case of emergency makeing mistakes in the unrest sometimes, and the Das Gaspedal mistake is stepped down as brake.When going to touch on the brake again, lacked enough braking times, thereby caused serious consequence Deng reacting.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of throttle emergency brake arrangement, can realize the function of brake at chaufeur in the misoperation accelerator pedal in the needs brake.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of throttle emergency brake arrangement, comprise brake gear, brake gear is communicated with brake oil pipe, brake oil pipe is connected with first brake pump, described brake oil pipe also is communicated with second brake pump, the motor of second brake pump is electrically connected with relay, relay is electrically connected with the mouth of controller, the first sensor and second sensor are electrically connected with the input end of controller, and the described first sensor and second sensor are installed near the Das Gaspedal.
The mouth of described controller also is electrically connected with oil path control system.
Described first sensor is different with respect to the distance of Das Gaspedal 11 with second sensor.
Described first sensor is installed in the position that the less stroke of Das Gaspedal can trigger, and the second sensor senses device is installed in the position that Das Gaspedal just can trigger near total travel.
Described controller is micro controller system or PLC.
Chaufeur is when steering vehicle, normal method of operation to Das Gaspedal should be: slowly accelerator pedal reaches the purpose of speed-raising, the situation that the anxious speed-raising of anxious accelerator pedal is also arranged sometimes, but the time of anxious accelerator pedal usually also can be greater than 0.1 second, and under the normal circumstances not hurriedly a pin floor.And when running into emergency situation and need stop immediately, the pedal that then touches on the brake with sudden force immediately reaches the purpose of sudden stop, and through overtesting, this sudden stop in emergency circumstances, the chaufeur pedal that touches on the brake is covered needed time＜0.01 of total travel second.
A kind of throttle emergency brake arrangement that the utility model provides, by two sensors are set below Das Gaspedal, measure the speed that Das Gaspedal is trampled, in brake fluid line, increase a cover second brake pump in addition, thereby realized to brake and realizing the function of brake, the safety that has improved vehicular drive greatly in the misoperation accelerator pedal at chaufeur.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of existing whole brake gear.
Fig. 2 is an integral structure scheme drawing of the present utility model.
The specific embodiment
In Fig. 1, when vehicle need brake, step on brake pedal 4 in the prior art, step on and step on promotion first brake pump 5 pistons extruding brake solution, be expressed to 4 brake gears, 2 brake wheels 1 again by brake oil pipe 3 brake solution, thereby reach the purpose of brake.
In Fig. 2, a kind of throttle emergency brake arrangement, comprise brake gear 2, brake gear 2 is communicated with brake oil pipe 3, and brake oil pipe 3 is connected with first brake pump 5, and described brake oil pipe 3 also is communicated with second brake pump 6, the motor 7 of second brake pump 6 is electrically connected with relay 8, relay 8 is electrically connected with the mouth of controller 9, and the first sensor 13 and second sensor 14 are electrically connected with the input end of controller 9, and the described first sensor 13 and second sensor 14 are installed near the Das Gaspedal 11.Described controller 9 is micro controller system or PLC.
The mouth of described controller 9 also is electrically connected with oil path control system 10.
Described first sensor 13 is different with respect to the distance of Das Gaspedal 11 with second sensor 14.Be that first sensor 13 is different with the distance of Das Gaspedal 11 with second sensor 14, walked the used time of total travel thereby measure Das Gaspedal 11.
Described first sensor 13 is installed in the position that Das Gaspedal 11 less strokes can trigger, and second sensor, 14 sensors are installed in the position that Das Gaspedal 11 just can trigger near total travel.Contact 12 is set on Das Gaspedal 11 usually is used to trigger the first sensor 13 and second sensor 14, the first sensor 13 and second sensor 14 can be travel switches, also can be opto-electronic pickup, adopt opto-electronic pickup to control sense better, and the travel switch price be comparatively cheap.
Whether the operation of accelerator pedal 11 belongs to normally in driving procedure, is judged jointly by the first sensor 13 and second sensor 14.
Mainly contain the judgement of following 4 kinds of situations.
First kind of situation: slow accelerator pedal 11, but do not floor, first sensor 13 sends signal, and second sensor, 14 no signals are the normal speed-raising of refueling.
Second kind of situation: quick accelerator pedal 11, but do not floor, promptly first sensor 13 sends signal, and second sensor, 14 no signals are the normal speed-raising of refueling.
The third situation: slow accelerator pedal, and floor, promptly the first sensor 13 and second sensor 14 all send signal, but because the pitch time between both signals is longer, are the normal speed-raising of refueling.
The 4th kind of situation: quick accelerator pedal, and floor, be that the first sensor 13 and second sensor 14 all send signal, and the time difference is less than the value of setting, for example 0.01 second, and this kind operation behavior has only in case of emergency just can occur, therefore, can be judged as is mistakenly Das Gaspedal 11 to be worked as brake pedal 4 to use.Then start brake system of the present utility model, vehicle emergency is stopped at once.
Concrete control flow is, controller 9 receives that the first sensor 13 and second sensor 14 all send signal, and the time difference is during less than the value set, outputing control signals to oil path control system 10 stops to driving engine supply fuel oil it, control signal control relay 8 starts simultaneously, motor 7 gets electric driving second brake pump 6 brake solution is injected in the brake oil pipe 3, promotes brake gear 2 with wheel 1 braking, the function of pedal emergency brake thereby realization is stepped on the throttle.
For 60 kilometers/hour of average highway Maximum speed limits, the time difference of the first sensor 13 and second sensor 14 is set to 0.01 second, and braking distance is about 0.17 meter; For 120 kilometers/hour of express highway Maximum speed limits, the time difference of the first sensor 13 and second sensor 14 is set to 0.1 second, and braking distance is about 3.33 meters.At the vehicle of running on expressway, navigating mate all is the attention high concentration, when there is something special in the place ahead, the capital finds that early more main is because owing to being to run at high speed, for safety, vehicle can not emergency brake, otherwise, the vehicle rollover accident will appear.Therefore, the native system time difference is set to 0.1 second, and braking distance is set to 3.33 meters.During the practice design, the time difference can be provided with in system according to actual conditions.
