Determine in process in technical scheme, in order to determine the optimum technology parameter of relief of blowing out, carry out the test of big quantity research, the real vehicle done including the superelevation speed per hour cap sensitive front-wheel etc. at speed up to 130-167.1 kilometer is blown out automatic-aid test, automatic-aid for high-speed tire explosion, draw following research conclusion: (1) Braking mode actuator, when adopting the existing brake pedal arm of automobile to implement retarding braking, from starting drag pedal arm setting in motion, to brake pedal arm being moved to the time that output maximum braking force position consumes, the longest must not exceed 2 seconds;(2) self-sustaining gear pulls the brake force size that pedal arm exports, it should for the 60-80% of this car design brake force;Above-mentioned running parameter, disclosure satisfy that time and the required braking force of the most dangerous high-speed tire explosion relief through the test of big quantity research;Otherwise, slow again or brake force is little again, high-speed tire explosion vehicle will be made cannot to utilize the inertia in original transport condition and direction, cannot effectively overcome the significant differences of blow out wheel and non-blow out resistance to rolling, rolling radius and side force etc. between wheel to cause high-speed tire explosion vehicle to miss best relief chance, cannot safety operation control, occur turning around, turn on one's side, the particularly serious vehicle accident of the car crash such as whipping;And brake force is excessive, unexpected brake hard is slowed down and will be caused on car not injury to personnel with good seat belt, also too fast rear portion pursuit-type vehicle can be caused because slowing down to have little time reaction and knock into the back, or dodge because dodging not as good as and with nearby vehicle collision and accidents caused;In addition, when native system actively implements Braking mode, driver will lean forward due to inertia health, foot is applied to the power on throttle will be increased, and needs the power of the releasing gas pedal that pulling device exports to be not less than in the positive situation of driver and step on the 300% of throttle power could effectively eliminate driver's acceleration function to vehicle for this;Meanwhile, release throttle and that clutch pedal is moved to time at the end is more early more good, it is desirable to be not later than 1.5 seconds, in order to avoid still causing various danger continuing to run at high speed after vehicle flat tire;Car braking and release the synergy of engine drive power, it will make to blow out, knock into the back, over-speed vehicles etc. is more easy to evades dangerous generation;
The present invention provides above-mentioned intelligent brake and automatically performs system, it installs additional and the existing system of automobile is not done any change, do not conflict with existing brakes, by the braking deceleration that brake pedal is implemented, anti-lock function and the vacuum servo function of the ABS of vehicle standard configuration can be made full use of, adapt to various vehicle, stable and reliable in work through testing this system.The control system of the present invention, for controlling the start and stop of actuating motor, rotation direction, speed, power output size etc., control system and motor adopt vehicle-mounted (12V or 24V) DC source to power, largest benefit is relatively excessive in output Braking mode power, or causing certain wheel lock up through wet and slippery, ice and snow road, the anti-lock function of ABS can ensure that driver's control to direction of traffic.
The present invention preferably has the reductor of auto-lock function, it is because needing quickly to pull braking footrest output effectual brake force with the fastest speed and enough moment, but by vehicular power-bottle voltage and capacity limit, available direct current generator effective power is only small again, though rotating speed is high but effectively output moment of torsion is limited;For this, first have to ensure there are enough output torques to produce enough brake force, this is accomplished by adopting reducing gear, but meet output brake force within the short time as far as possible again simultaneously, and existing Vehicular direct-current power of motor, under rated current and declared working condition, all cannot take into account the requirement of speed and moment;For this, it is a feature of the present invention that manage to utilize direct current generator stall operating mode implement Braking mode function;Because the direct current generator electric current when stall is about 5 times of rated current, the moment of torsion of output is also about 5 times of nominal torque, but motor cannot export and keep required brake force for a long time under this unconventional operating mode of stall, generally can only allow the stall time of several seconds, otherwise huge locked rotor current quickly can burn out motor insulating layer and cause short circuit, and initiation fire consequence is hardly imaginable.For this, for avoiding huge locked rotor current initiation fire, the present invention adopts the reducing gear with auto-lock function, is controlling the size of current that monitor in real time is carried by internal system, it has been found that motor occurs after locked rotor current, gives motor power-off in time.Now; because have employed turbine and worm, ball screw etc., there is the reducing gear of auto-lock function; after motor dead electricity; the position of reducing gear output shaft is locked; application position and the brake force of brake pedal are maintained; vehicle is slowing down with rational brake force, because controlling system to the timely power-off of motor, thus effectively protecting the motor of stall without damage;The spur reduction machine being do not have auto-lock function can also be adopted as an alternative, but on the output shaft of motor, increase brake;This device can be under control of the control system, when control system detects that motor is in stall resting position or other positions, receive the output shaft of the timely locked motor of instruction, the outgoing position system and the power that keep motor shaft are constant, now central control system is to motor power-off, it is to avoid motor continues stall work and damages.
Preferred version as the present invention, control system is as required, the size of brake force can be automatically controlled, its method is to control internal system set up variable resistance or adopt intelligent switch, by detecting and changing the size of current being supplied to direct current generator, thus the brake force size that actuator when regulating and controlling motor rotation blockage exports, such that it is able to realize motor to export sizable brake force.
After reaching retro-speed or braking purpose, it is necessary to system possesses the ability of Rapid reversal emergency brake function, otherwise lasting retarding braking can cause that vehicle is parked on fast or runway cannot to move initiation and the secondary vehicle accident such as knocks into the back.But the employing of various reducing gears, all can produce internal resistance in gear train, have employed the acceleration mechanism of auto-lock function, even if motor power-off, braking footrest cannot restore because of the existence of motor and speed reducer structure internal resistance and auto-lock function simultaneously.For this, solution provides reverse current for controlling system to timely motor, to have brake spur reduction machine, when releasing braking, can first release brake and the locking function of motor shaft is reoffered reverse current, such that it is able to eliminate the mechanical resistance of motor and speed reducer so that metal wheel is reversed, and each pedal resets under respective action of reset spring;
But because of different automobile types, when needing to move brake pedal to end generation brake force, the distance of motion or the number of turns of rotation vary, cause that control system is when reality controls reducing gear releasing Braking mode function, it is not easy to determine the how many circle of needs reversion very much, could both ensure that pedal loosened completely, it is unlikely to again because metal wheel exceedes the required reversion number of turns and opposite direction Wound steel rope, and pedal tension is produced brake force etc., and also be difficult to the motor reversal number of turns during actual enforcement accurately measure and control, and motor rotating frequently, to cause that vehicle cannot release braking in time, make vehicle stop cannot move on a highway uncontrolledly, thus causing that serious rear-end collision accident occurs;For this, spy, between the output shaft and metal wheel of reductor, sets up unilateral bearing, and metallic steel cord rolling wheel is enclosed within unilateral bearing.The function of unilateral bearing is to ensure that when the output shaft of actuator rotates forward, steel wire rope metal wheel Wound steel rope is driven to pull braking footrest to produce brake force, but during output shaft reversion, unilateral bearing is in idling conditions, metal rolling wheel thereon is no longer with the synchronized rotating in same direction of this output shaft, and is in free state.So, control system is when needs release Braking mode function, reverse current is provided to make it carry out several seconds or the lasting reverse rotation of suitable duration to motor by all means, unilateral bearing and metal rolling wheel thereon do not reverse with output shaft, steel wire rope thereon reverses under the pulling force of pedal back-moving spring, until brake pedal does not remain any pulling force on steel wire after resetting completely and stops the rotation, thus realizing Rapid reversal brake force, it also avoid the complex control of the number of turns that steel wire rope is reversed.Because braking footrest is very short for resetting time, stall after the reversing time that general control systems gives about 5 seconds, it is sufficient for pedal self-return;The releasing of other pedals is also adopted by similar fashion;
Preferred version as the present invention, can preferred turbine and worm motor, it is easy to reducing gear and has two outfans, one outfan connects braking footrest by steel wire rope, another outfan connects gas pedal by steel wire rope opposite direction, optimize size and the link position of two metal rolling wheels, when actuator so can be made to perform deceleration control, it is possible not only to move braking footrest to maximum apply position, pass through connecting rod simultaneously, opposite direction is by gas pedal fight back, reduce the driving force that electromotor is applied by driver, so that the deceleration of vehicle controls more efficient and steady.
Present invention is further characterized in that the metal rolling wheel of preferred variable diameter, for instance on the output shaft of reductor, be not the steel wire rope rolling wheel of the circles such as employing, but adopt eccentric cam structure.Because when braking footrest being moved to most position, the end, it is generally required to first overcome the idle stroke in pedal, master cylinder and wheel cylinder, at this moment do not need too big driving force, but by the restriction of motor and speed reducer structure rotating speed, pull the speed that pedal moves but cannot improve.For this, the purpose of employing cam or diameter-changing wheel structure, is to adopt radius Wound steel rope big as far as possible when starting to rotate, so that pedal to be quickly pulled to produce the position of brake force when same motor rotation speed;When brake pedal reaches maximum apply position, it is no longer necessary to produce displacement, and need to apply effectual brake force big as far as possible at this moment, now, steel wire rope is allowed to be in metal cam or the minimum driving radius place of diameter-changing wheel, now motor also can stall, can on motor shaft moment output maximum twist, produce be several times as much as major diameter or the pulling force of isodiametric wire rope pulley;So, the unique design of this diameter-changing wheel can in the situation of same motor speed, power of motor and reductor speed reducing ratio, and the brake force of the motor that is multiplied shortens again braking time at double, it is achieved the quickly purpose of brake hard.In like manner, when maintaining certain brake force, just can being adopted less locked rotor current by which, thus greatly reducing the caloric value of motor, extending life-span motor rotation blockage working time.In like manner, it is also possible to realize quick opposite direction and pull gas pedal, quickly reduce to engine oil purpose.
The key character of the present invention also resides in, very inconvenient feature is installed for automobile additional after carrying out, the present invention develops a kind of drop-down and that pressure working method is all suitable for down unique method that installs additional and installs parts additional, i.e. Nut column and n shape fixture block, application in conjunction with metal hose, it is possible to be easy to user and use flexibly according to the feature that automobile is different.
Structure shown in the above embodiment of the present invention and configuration are merely schematic.Although above-described embodiment is described in detail in the disclosure, but being without materially departing under the novel teachings of theme described herein and the premise of advantage, many improvement are all possible.
