End, an output end are connect with brake actuator 4 by conducting wire, and another output feeds back to controller 2 by conducting wire；
Step 7: when passenger has found fortuitous event, danger button a101 is pressed, danger button a101 is passed to controller 2
Delivery signal, controller 2 are issued to early warning loudspeaker 3 and are instructed；
Step 8: early warning loudspeaker 3 sound an alarm after receiving the instruction of controller 2, and are counted by timing controller 5
When, there are not other instruction inputs when timing reaches setting time, timing controller 5 issues braking instruction to brake actuator 4,
Brake actuator 4 starts to brake, and when braking to speed is zero or foot steps on brake pedal 8 or driver presses releasing button 7, system
Dynamic actuator 4 stops working, and early warning loudspeaker 3 stop early warning；
Step 9: early warning loudspeaker 3 sound an alarm after receiving the instruction of controller 2, and are counted by timing controller 5
When, speed is zero before timing reaches setting time or foot steps on brake pedal 8 or when driver presses releasing button 7, braking
Actuator 4 stops working, and early warning loudspeaker 3 stop early warning；
In the present embodiment, it is preferred that releasing button 7 is internally provided with electroluminescent lamp, by the way that electroluminescent lamp is arranged, when early warning loudspeaker
When 3 triggering, which, which synchronizes, is lighted, and is carried out next step operation after judging field conditions convenient for prompting driver, is prevented in flurried
It can not find releasing button 7 and cause unnecessary loss.
The working principle of the invention and process for using:
When monitoring driver tired driving, burst disease or leaving seat, camera is directly transmitted to controller
Danger signal triggers early warning loudspeaker 3, while passenger can directly touch by danger button 1, after danger button 1 triggers, early warning loudspeaker
3 horse backs make a sound early warning, and after early warning loudspeaker 3 sound, driver is not touched by releasing button 7, and timing controller 5 reaches
After the duration of setting, controller 2 assigns deceleration instruction to brake actuator immediately, after brake actuator 4 receives deceleration instruction,
It is immediately performed braking workmanship, so that vehicle automatic retarding, controller 2 draws a speed signal line and the speed of CAN bus is believed
The vehicle speed information of former vehicle is read in the docking of number line in real time, after the early warning loudspeaker 3 of the device issue emergency alarm sound prompting, is driven
The person of sailing if it is confirmed that the early warning be because passenger accidentally touch due to cause or driver confirm oneself can active operation vehicle deceleration when,
It can touch immediately by releasing button 7, with stop alarm, brake actuator 4 stops working, when speed is zero or foot steps on brake pedal 8
When, signal is transferred to controller 2, and issues stop working instruction, while early warning loudspeaker 3 to brake actuator 4 by controller 2
Stop early warning, early warning loudspeaker 3 are mounted on roof, convenient for sounding an alarm at the first time, reminds driver and passenger to occupy stably and help, with
It avoids automatic slow-down device when carrying out deceleration workmanship to vehicle, passenger is caused to fall down or squeeze the generation of event, danger button
A101 and danger button b102 is separately positioned at operation panel in front of the position of safe window breaking hammer and driver, when necessary
Driver can also trigger the button or reminding passengers trigger the danger button, the danger button a101 of passenger area is arranged close to
The position of the broken window of safety, finds the button at the first time convenient for passenger, and the position is relatively high, and it is naughty to avoid child
Accidentally touch the button, camera 6 is mounted at the interior roof in front of driver, facilitate camera 6 monitor driver sitting posture and
Position enables camera 6 to find dangerous situation at the first time and triggers early warning loudspeaker 3；
When having emergency case triggering early warning loudspeaker 3 and reaching specified duration, servo motor 20 starts, and drives driving gear
21 rotations, by the intermeshing realization slide bar 15 of driving gear 21 and rack gear 19 to moving inside slide cartridge 13, pressed home bullet
It drives driven gear 11 to rotate while spring 14, and then brake pedal 8 is driven to move down, be equal to driver's foot and step on braking and step on
Plate 8 brakes, and when triggering releasing button 7, servo motor 20 stops doing power immediately, the effect of the reset spring 14 of slide bar 15
Under reset immediately so that driven gear 11 is corresponding with groove 17, driven gear 11 is only by the independent role of brake pedal 8, no
It is influenced again by servo motor 20, re-operates driving vehicle convenient for driver；
When system identification to this vehicle speed is 0 kilometer/hour, emergency braking apparatus for vehicle is in masked state, at this time
Even if triggering danger button a101 or danger button b102 or camera 6 recognize driver's rest, leave seat etc., system
Alarm and braking deceleration function will not be triggered；
By the way that supporting mechanism 18 is arranged, slide bar 15 is fixed by backplate 181 and supporting plate 182, is subtracted by roller bar 183
Resistance when few movement of slide bar 15.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
