Principle of work of the present utility model:
When automatic catch automobile normally travels, whole automatic catch automobile accelerator and brake Anti-mis-stepping system is as the mode of operation of Fig. 1, during service brake, step on brake pedal, former master brake cylinder works, and hydraulic oil promotes steel current limliting ball valve through master brake cylinder output circuit and moves down until prop up the lower ball valve locating dowel pin of below, now, the delivery valve of auxiliary braking master cylinder is the state blocked, and the hydraulic oil of former master brake cylinder flows out total output circuit and enters wheel cylinder and complete braking, and in this process normally travelled, dynamics during chaufeur accelerator pedal can not more than tens newton, now force snesor does not work, electromagnet does not work, π sections matter strut bar is in indentation state, although can left and right displacement be there is in the Das Gaspedal control stalk that Das Gaspedal connects, and the second rigid posts can be driven to swing by the first rigid posts, but any stretching can not be there is to link pull bar, make Solenoid ball valve controller and link rod head hemispherical groove and engage position and cannot contact, now auxiliary braking master cylinder is in off position, do not affect normal driving conditions.
When automatic catch automobile being unfamiliar with and occurring in an emergency situation to step on phenomenon due to chaufeur by mistake, violent has trampled Das Gaspedal, whole automatic catch automobile accelerator and brake Anti-mis-stepping system is as the mode of operation of Fig. 2, due in the process of suddenly stepping on, the power being close to several times at ordinary times can be produced, force snesor in Das Gaspedal commences work without delay after sensing this abnormal power, produce large current and make work of electromagnet, the pulling force attracting π sections matter strut bar to overcome extension spring stretches out cylindrical box, and the Das Gaspedal control stalk that now Das Gaspedal connects moves right to the first rigid posts generation thrust, and make it rotate around the 3rd revolute pair linked on pull bar to the second rigid posts two ends generation moment further, now due to the relation of locus, in second rigid posts, certain can be against on π sections matter strut bar, along with the further rotation of the second rigid posts, because lever principle can make the 3rd revolute pair on link pull bar be subject to contrary thrust, thus link pull bar is subjected to displacement left, the piston that link pull bar connects can overcome Compress Spring compression hydraulic oil left, air can enter auxiliary braking master cylinder inner equilibrium air pressure from the admission port of auxiliary braking master cylinder, and now fuel tank is in closed condition under the effect of ball check valve, so hydraulic oil can only enter master brake cylinder output circuit by the outlet on auxiliary braking master cylinder top, promote steel current limliting ball valve until prop up the upper ball valve locating dowel pin of top, now the output circuit of former master brake cylinder is plugged, the hydraulic oil extruded by auxiliary braking master cylinder enters total output circuit and acts on each wheel cylinder, simultaneously, Solenoid ball valve controller with link rod head and there occurs relative displacement, the hemispherical groove of link rod head is snapped in object that Solenoid ball valve controller serves continuous action, after chaufeur recognizes oneself misoperation accelerator pedal, unclamp Das Gaspedal, then step on brake pedal, circuit now on brake pedal connects the work of electromagnet on Solenoid ball valve controller, attract the ball valve rod in Solenoid ball valve controller, open ball valve, Solenoid ball valve controller with link pull bar and unclamp, link pull bar return under the effect of Compress Spring, simultaneously because the power in Das Gaspedal disappears, electromagnet no longer works, the return indentation under the effect of extension spring of π sections matter strut bar, because in previous auxiliary braking master cylinder, hydraulic oil is forced out, open under the gas pressure having vacuum to make ball check valve in fuel tank, hydraulic oil in fuel tank enters in auxiliary braking master cylinder, serve supplementary function in order to lower task, and normal work now is former master brake cylinder, under the effect of steel current limliting ball valve, the master brake cylinder output circuit above auxiliary braking master cylinder is closed again.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Automatic catch automobile accelerator and brake Anti-mis-stepping system of the present utility model, the operation that driver fault misstepping on accelerator is different with normal step on the accelerator two kinds is judged by force snesor, accurately swift with judgement, drag is carried out again by auxiliary oil way, thus the generation tried to forestall traffic accidents, system response time is fast, accuracy and reliability high, degree of automation is high, can the startup of completion system and return automatically, chaufeur is saved worry laborsaving; When system is judged as mis-accelerator pressing, automobile stop control lever emergency braking, the potential safety hazard that chaufeur is in case of emergency stepped on by mistake can be eliminated, chaufeur recognize step on by mistake after change touch on the brake time, system self-return, neither influential system works next time, and in turn ensure that the safety of chaufeur, safety factor is high; In addition, automatic catch automobile accelerator and brake Anti-mis-stepping system of the present utility model, being brake by increasing auxiliary oil way, just can having an effect when driver's operation is slipped up, errorless when stepping on situation system inoperative, do not affect the normal traveling of automobile completely.
