Accompanying drawing explanation
To be that gas described in the utility model is anti-error step on the total attachment structure schematic diagram of device to Fig. 1.
Fig. 2 is brake pedal driver train mounting structure schematic diagram described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification sheets word to make those skilled in the art.
As shown in Fig. 1 Fig. 2, the utility model provides that a kind of gas is anti-error steps on device, comprise accelerator pedal position sensor 1, brake pedal driver train and controller 8, accelerator pedal position sensor 1 is connected with Das Gaspedal 2, position is trampled for what measure Das Gaspedal 2, and the data of measurement are passed to controller 8 in real time, brake pedal driver train is connected with brake pedal 7, controller 8 can control the work of brake pedal driver train, drive brake pedal 7 to pressing down, thus carry out brake.Pass through this set, the data that controller 8 can be measured according to accelerator pedal position sensor 1 judge that whether throttle is mistakened as by operator and having done brake use, when being judged as YES, controller 8 can control the work of brake pedal driver train immediately, drive brake pedal 7 to be pressed downwardly onto the end to brake, thus avoid the generation of accident.
Described brake pedal driver train comprises brake and controls motor 6, worm screw 13 and tooth bar 14, they are installed on the shoe sole 9 below brake pedal 7, brake pedal 7 is hinged by turning cylinder 10 and shoe sole 9, it is a DC micromotor that brake controls motor 6, brake controls motor 6 and is coaxially fixedly connected with described worm screw 13, worm screw 13 engages with tooth bar 14, tooth bar 14 is connected with brake pedal 7, one bearing 8 is installed above tooth bar 14, bearing 8 is connected with brake pedal 7 upper surface, brake controls motor 6 and rotates along brake motor rotation direction, worm screw 13 is driven to rotate, thus band carry-over bar 14 moves down, bearing 8 on tooth bar 14 can produce a downward pressure to brake pedal 7, brake pedal 7 is moved in brake pedal normality activity space along brake sense of motion, simulation trample action, vehicle is braked.
In technique scheme, described brake pedal driver train also comprises the guide plate of gear rack 15, and it is slidably connected with described tooth bar 14, and the described guide plate of gear rack 15 can limit the sense of motion of tooth bar 14, and tooth bar 14 can only be slided along the direction of guide plate 15.
In another embodiment, the anti-error device of stepping on of described gas also comprises throttle gate 4 and throttle control motor 5, and throttle motor 5 is connected with throttle gate 4, can control the opening and closing degree of throttle gate 4, throttle motor 5 is connected with controller 8, is controlled by controller 8.When controller 8 judge operator throttle is mistakened as having done brake use time, can control throttle motor 5 and work, close the throttle 4 makes engine off, to produce towing astern braking force, reduces the speed of a motor vehicle fast further.
In another embodiment, throttle gate 4 is also provided with valve position sensor, it can detect the aperture of described throttle gate 4 and detection signal be passed to described controller 8, and controller 8 can control the running state of throttle motor 5 according to throttle opening amount signal.
