When the mistake step on the gas takes place will have an accident the time in the driver, sensitive switch K0 conducting, battery D2 produces DC speed-reducing 1 is just changeing the realization brake process, and the brake time is at least greater than three seconds kinds, the vehicle state of stop motion of being stopped.After accident was removed, the driver decontroled throttle, and sensitive switch K0 disconnects, and battery D2 makes DC speed-reducing 1 produce counter-rotating and realizes removing brake.When DC speed-reducing 1 was inverted to the armed state position, master cock K6 conducting was then disconnected by control K switch 5, and no longer to DC speed-reducing 1 power supply, total system comes back to armed state to battery D2.
When the obstacle of the car speed that travels and front is not in safe range, mouth K switch 7 conductings of anticollision controller 11, battery D2 produces DC speed-reducing 1 is just changeing the slowing-down brake process that realizes being less than three seconds kinds, car retardation is when vehicle and front obstacle are in safe range, mouth K switch 7 disconnects, and battery D2 makes DC speed-reducing 1 produce counter-rotating and realizes removing brake.Because the unsafe range that car speed and front obstacle form is a continuous variable, then DC speed-reducing 1 produces and is just changeing the time of realizing slowing-down brake and also be into the continuous variable that correlativity changes with degree of deceleration.Owing to be the mechanical structure form realization slowing-down brake that drives drive wires 10 with the rolling disc 7 of the motor assembly 3 of being with limit switch, then realize removing in the brake process in DC speed-reducing 1 counter-rotating, speed and obstacle appear again not in safe range the time, mouth K switch 7 conductings immediately again start DC speed-reducing 1 and are just changeing the realization slowing-down brake at once again.Be that DC speed-reducing 1 does not need to reset to fully armed state, but in the counter-rotating reseting procedure, can carry out slowing-down brake again again, this anti-collision retarding brake function that not placed restrictions on by DC speed-reducing 1 turned position, can satisfy speed and obstacle unsafe range fully is a continuous variable's requirement.Can satisfy the requirement that whenever can start the anti-collision retarding brake.
The rolling disc 7 that is positioned in DC speed-reducing 1 rotating shaft is eccentric wheel structure.Drive wire 10 is connected DC speed-reducing 1 when just changeing, and point of connection is in eccentric rotary dish 7 rotational line speed positions from large to small.Because of when beginning brake, drive wire 10 is stressed little and require braking automobile pedal 5 fast to the speed of brake direction motion; After treating that braking automobile pedal 5 has been in normal danger, drive wire 10 is stressed big and displacement is few.Before car accedent did not have releasing, braking automobile pedal 5 should continue to be in final normal danger, then just requires DC speed-reducing 1 to be in the stall state, and the drive wire 10 of stall state is stressed big.
The sidewall of rolling disc 7 has circular groove, and drive wire 10 is connected in the circular groove of rolling disc 7, and the backguy hole 9 of shell 6 is corresponding with the circular groove position of rolling disc 7.Purpose is to limit drive wire 10 and moves in the circular groove of rolling disc 7, with the particularity of assurance drive wire 10 motion length, thereby guarantees at accident condition, carries out the reliability of emergency brake with system of the present utility model.
Serve as that the mistake of mistake step on the gas is stepped on threshold value with mistake step on the gas action to the minimum force of Das Gaspedal; In the time of contacting conduction with two contacts of sensitive switch K0, the elastic element elastic force of sensitive switch K0 is switching threshold; The position that sensitive switch K0 arranges makes switching threshold just in time express mistake and steps on threshold value, and namely the position that arranges of sensitive switch K0 makes switching threshold and misses that to step on threshold value corresponding;
Sensitive switch K0 after therein elastic element is subjected to the switching threshold pressure distortion, can contact two conductive contact pieces of switch, produces the switch that conduction is connected.
Sensitive switch K0 is spring loaded sensitive switch K0 or dish formula sensitive switch K0;
Spring loaded sensitive switch K0 comprises slide cartridge, hollow type coil spring, criss-cross piston and two conductive contact pieces; The hollow type coil spring is located among the slide cartridge, and the helical spring two ends of hollow type contact the bottom of slide cartridge and the piston plate of criss-cross piston respectively; The piston plate of criss-cross piston is positioned at the top of slide cartridge, the center pillar of criss-cross piston stretches out the mesopore that slide cartridge has the top cover of mesopore for one section, the top of this center pillar section of stretching out is provided with force block, another section of the center pillar of criss-cross piston is positioned at the helical spring circle of hollow type, and the termination of this center pillar in spring coil is provided with conductive contact piece; In the hollow type spiral elastic ring of slide cartridge bottom a conductive contact piece is arranged fixedly also; There are minim gap and position corresponding between the conductive contact piece of the conductive contact piece of center pillar termination bottom slide cartridge;
Dish formula sensitive switch K0 comprises an elasticity concave surface piece, nonelastic base plate and two conductive contact pieces; The concave surface of elasticity concave surface piece is mutually permanently connected to the direction of nonelastic base plate, and among the interior sky of elasticity concave surface piece and nonelastic base plate, a conductive contact piece is fixed on the surface of elasticity concave surface piece, and another conductive contact piece is fixed on the surface of nonelastic base plate; Minim gap and position correspondence are arranged between two conductive contact pieces.
The car body position of described Das Gaspedal correspondence refers to: in the normal fueling state of automobile, Das Gaspedal refuel sense of motion pointed the fixed parts band of position, and be that Das Gaspedal is refueled the fixed parts band of position that motion approached.
The car body position of described Das Gaspedal connecting rod correspondence refers to: in the normal fueling state of automobile, the Das Gaspedal connecting rod refuel sense of motion pointed the fixed parts band of position, and be that the Das Gaspedal connecting rod refuels the fixed parts band of position that motion approached.
The elasticity modulus setting pressure switching threshold that sensitive switch K0 selects for use elastic element to be fit to, step on threshold value if the strength of setting the pin accelerator pedal is the mistake of Das Gaspedal during more than or equal to 10 kilograms, mistake is stepped on threshold value makes the sensitive switch K0 that sensitive switch K0 can conducting stressed as switching threshold.Under the switching threshold state, sensitive switch K0 conducting.The strength of pin accelerator pedal is stepped on threshold value less than mistake, and sensitive switch K0 is stressed less than switching threshold, and sensitive switch K0 becomes off-state, and throttle normally refuels the raising speed of a motor vehicle.
As long as connect with the mains at two conductive contact pieces of sensitive switch K0, when two conductive contact piece contacts, sensitive switch K0 just can export electric signal.This electric signal is as the sign of wrong step on the gas behavior, and as the actuation signal of follow-up correction mistake step on the gas action.
In other words, make two contacts of sensitive switch K0 can contact the minimum strength of conducting electricity, the minimum strength that the people sends when needing not be equal to the mistake step on the gas.Will send electric signal with two contacts contact conduction of sensitive switch K0 and represent wrong step on the gas behavior, the minimum strength that the people sent when then the position that will arrange with sensitive switch K0 and these two key elements of minimum strength ［ being switching threshold ］ that can contact conduction cooperated ability correctly to represent step on the gas by mistake ［ is stepped on threshold value ］ by mistake.That is to say that it is to represent to step on threshold value with the position of sensitive switch K0 setting and the cooperation of switching threshold that the mistake of missing step on the gas is stepped on threshold value by mistake.If it is 10 kilograms that mistake step on the gas mistake is stepped on threshold value, sensitive switch K0 is arranged on the Das Gaspedal connecting rod between Das Gaspedal and the Das Gaspedal run-on point, because the power of the sensitive switch K0 back of the body is shorter than the power back of the body of Das Gaspedal, according to lever principle, switching threshold is that two contacts of sensitive switch K0 can contact when conducting electricity, and the minimum elastic force of the elastic element of sensitive switch K0 should be greater than 10 kilograms.If it is constant that setting mistake step on the gas mistake is stepped on 10 kilograms of threshold values, but the position difference that sensitive switch K0 arranges, the switching threshold of elastic element is also different.Generally speaking, mistake step on the gas mistake is stepped on the switching threshold that threshold value is not equal to elastic element.So, a fixing sensitive switch K0 of switching threshold can only be arranged on some ad-hoc locations of Das Gaspedal or Das Gaspedal connecting rod, just can make sensitive switch K0 normal operation, be that switching threshold could correct be expressed mistake and be stepped on threshold value, namely the position that arranges of sensitive switch K0 makes switching threshold and to step on threshold value corresponding by mistake.
Sensitive switch K0 experiences Das Gaspedal and the stressed device of Das Gaspedal connecting rod, so can sensitive switch K0 be set in Das Gaspedal or the Das Gaspedal rod surface towards car body, perhaps be provided with sensitive switch K0 at the car body position of Das Gaspedal or Das Gaspedal connecting rod correspondence.
Because sensitive switch K0 is located on the Das Gaspedal connecting rod, or pad pin blanket on the indoor floor can be avoided driving in these two positions, K0 is normally stressed for the article overslaugh sensitive switch that drops on the car body position of Das Gaspedal connecting rod correspondence.From the reliability aspect of sensitive switch K0 impression mistake step on the gas action, sensitive switch K0 is located at the Das Gaspedal rod surface towards car body, or there is reliability preferably at the car body position that is located at Das Gaspedal connecting rod correspondence.
Sensitive switch K0 is spring loaded sensitive switch K0 or dish formula pressure activated switch:
Spring loaded sensitive switch K0 comprises slide cartridge, hollow type coil spring, criss-cross piston and two conductive contact pieces; The hollow type coil spring is located among the slide cartridge, and the helical spring two ends of hollow type contact the bottom of slide cartridge and the piston plate of criss-cross piston respectively; The piston plate of criss-cross piston is positioned at the top of slide cartridge, the center pillar of criss-cross piston stretches out the mesopore that slide cartridge has the top cover of mesopore for one section, the top of this center pillar section of stretching out is provided with force block, another section of the center pillar of criss-cross piston is positioned at the helical spring circle of hollow type, and the termination of this center pillar in spring coil is provided with conductive contact piece; In the hollow type spiral elastic ring of slide cartridge bottom a conductive contact piece is arranged fixedly also; There are minim gap and position corresponding between the conductive contact piece of the conductive contact piece of center pillar termination bottom slide cartridge.
The elasticity modulus setting pressure switching threshold that spring loaded sensitive switch K0 selects for use spring to be fit to, if being the mistake of Das Gaspedal during more than or equal to 10 kilograms, the strength of setting the pin accelerator pedal steps on threshold value, mistake is stepped on threshold value makes spring stress that spring loaded sensitive switch K0 can conducting as the pressure switch threshold value, the spring stress numerical value when switching threshold is exactly the spring conductive contact piece that is compressed to the center pillar termination with the conductive contact piece energy position contacting of slide cartridge bottom.Under the switching threshold state, spring loaded sensitive switch K0 conducting.When the strength of pin accelerator pedal was stepped on 10 kilograms of threshold values less than mistake, spring loaded sensitive switch K0 was stressed less than switching threshold, and spring loaded sensitive switch K0 becomes off-state, and throttle normally refuels the raising speed of a motor vehicle.
Dish formula sensitive switch K0 comprises an elasticity concave surface piece, nonelastic base plate and two conductive contact pieces; The concave surface of elasticity concave surface piece is mutually permanently connected to the direction of nonelastic base plate, and among the interior sky of elasticity concave surface piece and nonelastic base plate, a conductive contact piece is fixed on the surface of elasticity concave surface piece, and another conductive contact piece is fixed on the surface of nonelastic base plate; Minim gap and position correspondence are arranged between two conductive contact pieces.
The elasticity modulus setting pressure switching threshold that dish formula sensitive switch K0 selects for use elasticity concave surface piece to be fit to, if being the mistake of Das Gaspedal during more than or equal to 10 kilograms, the strength of setting the pin accelerator pedal steps on threshold value, mistake is stepped on threshold value makes the elasticity concave surface piece that dish formula sensitive switch K0 can conducting stressed as the pressure switch threshold value, and switching threshold is exactly two conductive contact pieces on elasticity concave surface piece and the nonelastic base plate stressed numerical value of elasticity concave surface piece can position contacting the time.Under the switching threshold state, dish formula sensitive switch K0 conducting.When the strength of pin accelerator pedal was stepped on 10 kilograms of threshold values less than mistake, K0 was stressed less than switching threshold for dish formula sensitive switch, and dish formula sensitive switch K0 becomes off-state, and throttle normally refuels the raising speed of a motor vehicle.
The characteristics of sensitive switch K0 are to set the switching threshold of mistake step on the gas strength with the elasticity modulus of elastic element.Switching threshold is stepped on threshold value with mistake and is not necessarily equated, but necessarily corresponding, and when namely Das Gaspedal was subjected to stepping on the strength of threshold value by mistake, sensitive switch K0 necessarily was in the switching threshold state.
Sensitive switch K0 is the switch of gathering mistake step on the gas signal, is the automatic switch that satisfies rated condition, namely after Das Gaspedal is stepped on excessive too quickly strength by the driver, and the automatically actuated switch of energy.
Advantage of the present utility model: relay is swung to power-supply controller and is far superior to the relay switch combination of micro controller as the power switch of swinging to of direct supply with reliability, be that relay is swung to power-supply controller to three states of slowing-down brake or mis-accelerator pressing error correction brake with this relay reversing switch---brake started, remove brake, reposition is controlled, and makes the controller of slowing-down brake or mis-accelerator pressing error correction brake system have high reliability.In addition, relay is swung to two cycle of states of slowing-down brake that power-supply controller can also be realized the requirement of anticollision controller---start and brake, remove brake, restart brake, remove brake again ... can DC speed-reducing do not get back to initial condition the return process in, circulation starts brake and removes the effect of brake.
Sensitive switch K0 gathers the signal that step on the gas signal, the collection of anticollision controller by mistake need slowing-down brake.Because the mouth K switch 7 of sensitive switch K0 and anticollision controller is in parallel, then can swing to power-supply controller and the motor assembly of being with limit switch by public relay to mistake step on the gas error correction brake and slowing-down brake.Owing to be that few chance is used to mistake step on the gas error correction brake, and in case use the reliability of essential height, still, long-term not use system is difficult to guarantee to take place to have the time spent in accident the reliability of height.And the slowing-down brake in the native system is function used in everyday, daily use slowing-down brake function, but then played the whether well effect of step on the gas accident by mistake of emergency handling of daily detection mistake step on the gas error correction brake system.Be that slowing-down brake function of the present utility model provides the routine detection for missing step on the gas error correction brake function, make the mistake step on the gas error correction brake function of avoiding serious accident have reliability.
The signal probe of anticollision controller is the sensor of measuring automobile and the dynamic distance between the obstacle of the place ahead of travelling in travelling, and certain signal probe can also have the sensing to other content again.Signal probe is placed on the automobile front, and the automobile that then can play in normally travelling prevents and the collision of the place ahead obstacle, can also prevent from colliding with the place ahead obstacle when starting or stop; Signal probe is placed on the automobile back, can prevent from colliding with rear obstacle when starting or stop.Namely can solve normally and travel, start and automobile and obstacle collision when stopping.
Rolling disc setting at shell and execution mechanical action is master cock K6 with turned position location information related controlled reset switch, remove the brake rotary state when removing from accident with master cock K6 controlled reset DC speed-reducing and become the reposition stop motion, wait for next time and restart the state of brake.
The rolling disc that connects on DC speed-reducing eccentric rotary dish is suitable for starting soon, and strength needs big mis-accelerator pressing error correction system job requirement characteristics during stall.
Can directly obtain mistake step on the gas signal, do not need pressure sensor with microelectronic circuit to weight different foot throttle behaviors analyze the step on the gas behavior that misses of finding out.As long as pressure activated switch of the present utility model is arranged on the ad-hoc location that can express accelerator pedal displacement and can express the Das Gaspedal strained condition, just can obtain mistake step on the gas switched electrical signal with the method for directly setting the switching threshold of elastic element again.
