Abstract
The invention discloses an electric braking control system against mistakenly stepping on an accelerator during braking. The electric braking control system comprises a braking control system against mistakenly stepping on the accelerator during braking and a protection device, wherein the braking control system against mistakenly stepping on the accelerator during braking comprises a braking control system, an oil supply control system, a warning device, a preparation device, a car accelerator pedal movement speed signal generator and a PLC (Programmable Logic Controller). When the accelerator of a car is abnormally stepped on, acceleration can be changed into braking automatically and instantly; and since a digital quantity signal generated by the car accelerator pedal movement speed signal generator in real time can be directly recognized by the PLC, the speed of the overall system in response to braking is ensured to be higher. The protection device is used for providing a signal to the PLC when the car overtakes and accelerates normally, the PLC automatically blocks possible error output at the time, so that the potential safety hazard brought by missing of additional operations is eliminated; when the car drives normally, the PLC unblocks the output blockage automatically, so that the system performs normally to ensure that driving of the car is safer.
Description
Technical field
The present invention relates to a kind of accelerator instead of brake deceleration of electrons control system.
Background technology
It is the invention case of CN102139641A that State Intellectual Property Office discloses publication number on August 3rd, 2011, and this case discloses a kind of changeable accelerator instead of brake control system, and it is made up of accelerator instead of brake intelligence control system and electromagnetic valve, switch key; Its intelligence control system mainly contains read-out, brake system, PLC, throttle signal generator and pressure sensor and forms; Throttle signal producer and pressure sensor change vehicle accelerator pedal pressure into electric signal; This signal is compared by the parameter of PLC and setting; When this abnormal signal, the PLC output command, the original brake system of PLC instruction executing device and vehicle realizes car brakeing; Read-out is the window of summary display various information; For preventing that vehicle is at the brake signal of PLC output error need trample throttle suddenly time of normally overtaking other vehicles; It has adopted electromagnetic valve and switch key to carry out manual switchover; Be used for reducing the signal value of pressure sensor output, cause not output of PLC, guaranteed the performance of the normal acceleration capability of vehicle.
Yet said system still exists when using and does not attain perfect disappearance:
(1) electric signal of pressure sensor generation is an analog quantity; The analog quantity electric signal must pass through special functional module processing back PLC and could discern; This just must increase functional module, has increased the time of signal input PLC thus, and the read-out content displayed also must obtain the communication support of PLC simultaneously; The scanning period that this has just prolonged PLC inevitably, prolonged the time of total system response braking thus.
(2) switch key must be switched by the extra M/C of driver and conductor, and structure is loaded down with trivial details, in case omit this operation, vehicle is normally overtaken other vehicles when trampling throttle suddenly, still has huge secret worry.
Summary of the invention
For overcoming the deficiency of prior art; The technical matters that the present invention will solve provides a kind of accelerator instead of brake deceleration of electrons control system; Not only make the speed of total system response braking faster; And making system when vehicle is normally overtaken other vehicles, the driver and conductor needn't just can guarantee vehicle safe driving by operation bidirectional.
For addressing the above problem, the technical scheme that the present invention adopts is:
(1) accelerator instead of brake braking control system, it comprises:
One braking control system is mainly carried out the PLC instruction by relay, electromagnetic valve, and is acted on the original brake system of vehicle, and when being used for accelerator instead of brake, instantaneous realization vehicle is by quickening to become braking;
One control of fuel supply system mainly carries out the PLC instruction by relay, electromagnetic valve, and acts on the original fuel-feed system of vehicle, when being used for accelerator instead of brake, reduces the vehicle motor rotating speed rapidly;
One alarming device mainly is a phonetic alarm, is used to remind the kinematic velocity of vehicle accelerator pedal to reach the critical conditions that is converted into abnormal speed by normal speed;
One prepares device, carries out the PLC instruction by relay, and acts on the original side-marker lamp of vehicle mechanism, stoplight stop lamp mechanism, is used to open side-marker lamp, stoplight stop lamp;
One vehicle accelerator pedal travel speed signal generator; This signal generator is by shell, feeler lever, hold-down arm, slide block, wheel, guide rail, the axis of guide, retracing spring, metallic object, fixed support, form near switch; Be used to produce the real-time electric signal of one group of vehicle accelerator pedal travel speed; Hold-down arm stretches out with feeler lever from the fluting of outer casing bottom and is connected, hold-down arm be connected slide block below, metallic object be embedded in slide block above; Slide block can move on guide rail under wheel and axis of guide combined action; Retracing spring is consistent the kinematic velocity of slide block and vehicle accelerator pedal, and the snap action of arranging according to certain rules that passes through at metallic object near switch produces set of number amount electric signal in real time;
One PLC; Be used for signal and setup parameter that vehicle accelerator pedal travel speed signal generator produces are compared, and make right judgement, PLC is electrically connected with braking control system respectively; System is electrically connected with control of fuel supply; Be electrically connected with alarming device, be electrically connected, be electrically connected with vehicle accelerator pedal travel speed signal generator with preparation device.
(2) fender guard is a relay, and it receives the Vehicular turn signal control, and being used for vehicle provides a digital quantity signal to PLC when normally overtaking other vehicles, and the PLC executive routine blocks possible mistake output, the normal performance of support vehicles acceleration capability automatically.
The invention has the beneficial effects as follows: a kind of accelerator instead of brake deceleration of electrons control system is provided; The electric signal that the vehicle accelerator pedal travel speed signal generator that native system adopts produces in real time is the digital quantity that PLC can Direct Recognition; Saved intermediate link, made the time of native system response braking shorter, simultaneously owing to adopt alarming device to replace read-out; Also shortened the scanning period of PLC, this has just improved total system response braking reaction speed accordingly; On the other hand; When vehicle was normally overtaken other vehicles, fender guard was along with the correct steering operation of vehicle is exported the digital quantity electric signal automatically to PLC, PLC executive routine; Automatically block possible mistake output, eliminated the driver and conductor because of omitting the safe secret worry that operation bidirectional brings; This shows that not only when accelerator instead of brake took place, moment realized that vehicle becomes braking by acceleration to native system, and does not hinder the normal performance of vehicle accelerating ability ability, the safety that has improved vehicle is more reliable.
