Detailed description of the invention
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
With reference to Fig. 1, the preferred embodiment of the present invention provides a kind of multi-functional automatic hand brake system, multi-functional automatic hand brake system comprises braking mechanism 41, the actuating device 40 be connected with braking mechanism 41, the central controller 10 that is electrically connected with actuating device 40, and central controller 10 is also electrically connected:
Car door inductor 30, for generating corresponding car door signal according to the state that opens or closes of car door;
Be located at the human body infrared induction installation 50 on compartment inwall, for detecting operator seat, whether someone exists;
Be located at the distance measurement sensor 90 of headstock, for generating corresponding spacing signal according to the spacing between institute's steering vehicle and front vehicles;
Voice controller 80 and the sound-producing device 81 be electrically connected with voice controller 80, for producing audible alarm when spacing signal transfinites and/or car door is not closed;
Speed sensor 70, for detecting the moving velocity of vehicle and generating corresponding speed signal;
Be located at the brake pedal induction installation 20 at brake pedal plate place, brake pedal induction installation 20 is for triggering a brake pedal signal when brake pedal depresses;
Actuating device 40 for driving brake mechanism 41 to limit tyre rotation.
The multi-functional automatic hand brake system of the preferred embodiment of the present invention is provided with car door inductor 30, human body infrared induction installation 50, when there is no a chaufeur when car door opening or in vehicular drive position or stationary vehicle time, braking mechanism 41 locks tire, ensures the reliability of vehicle brake function when stopping.Simultaneously, the multi-functional automatic hand brake system of the preferred embodiment of the present invention is also provided with speed sensor 70 and distance measurement sensor 90, can be reported to the police by sound-producing device 81 in real time according to the speed of a motor vehicle and front-and-rear vehicle distance situation, remain a safe distance behind the car in front and safe velocity to point out driver and crew to note, and when the speed of a motor vehicle transfinites, control braking mechanism 41 by actuating device 40 and limit tyre rotation.
Under existing brake technique condition, all adopt the mode of directly trampling Das Gaspedal oil supply when vehicle is from parking to the process started.Because the individual difference of chaufeur is different with driving habit, often there is the situation that oil supply is too much.The preferred embodiment of the present invention also possesses brake pedal induction installation 20, specifically, after vehicle realizes parking by handbrake mechanism, before vehicle reruns, need to detect chaufeur by this brake pedal induction installation 20 whether service brake is stepped on, only after chaufeur steps on service brake, handbrake mechanism just can remove the restriction to tire, by this kind of mode, can prevent that chaufeur oil supply when vehicle launch is excessive makes vehicle acceleration too quickly, effectively avoid therefore and knocking into the back or traffic accident of producing.
Alternatively, central controller 10 is also electrically connected a bus network controller and a bus interface be electrically connected with bus network controller.By bus interface modes, make the preferred embodiment of the present invention can directly and the bus topology system communication of automobile, compatibility significantly strengthens.
Alternatively, bus network controller comprises CAN controller or 485 bus controllers.Alternatively, the preferred embodiment of the present invention can configure both simultaneously, to further expand Applicable scope.
Human body infrared induction installation 50 on the compartment roof of operator seat, install at least one.Detect downwards from compartment roof, detection position possesses specific aim more, and safe reliability is higher.If because be arranged on the front of chaufeur, human body infrared induction installation 50 easily senses the occupant riding on back seat, and then brake system is caused to occur erroneous judgement.
More specifically, human body infrared induction installation 50 installs at least one at the top of co-driver and/or back seat.Whether there is occupant by detection co-driver and back seat, when occupant having been detected, driving voice controller 80 by central controller 10, then drive sound-producing device 81 to produce safety alarm prompting by voice controller 80, note safety by bus to point out occupant.Alternatively, voice controller 80 is also electrically connected with information storage chip, multiple cue data are prestored in this information storage chip, the preferred embodiment of the present invention directly reads cue data from information storage chip, significantly reduce taking of central controller, effectively improve the operating efficiency of whole system.
Further, distance measurement sensor 90 comprises sound ranging device or laser ranging system.In more detail, distance measurement sensor 90 generates range signal value, and the braking strength of braking mechanism 41 controls by actuating device 40, and this braking strength is inversely proportional to range signal value size, is directly proportional to speed signal value size.
Alternatively, central controller 10 is also electrically connected an acceleration pick-up 70, and acceleration pick-up 70 is for detecting the ramp inclination degree of vehicle traveling and generating corresponding steepness signals.More particularly, actuating device 40 controls the braking strength of braking mechanism 41 according to being in proportion of steepness signals value.Because the easy premature abrasion brake disc of brake modes of long-time high strength and tire, the preferred embodiment of the present invention to the braking strength differentiation that tire applies, effectively extends the period of service of brake system on different road surfaces.
Alternatively, central controller 10 is also electrically connected the Das Gaspedal induction installation 60 that is located at accelerator pedal place, and pedal induction installation is used for triggering an accelerator pedal signal when accelerator pedal depresses.More specifically, this accelerator pedal signal coordinates with brake pedal signal, and when braking mechanism 41 does not remove the restriction to tire, shielding or restriction Das Gaspedal are to the control action of giving oil mass.When parking starts, if chaufeur does not trigger brake pedal signal in advance, then the restriction sustainable existence of braking mechanism 41 pairs of tires, even if chaufeur oil supply when parking starts is excessive, also there will not be the situation that vehicle acceleration is too quickly, avoid the therefore rough sledding caused.
In addition, central controller 10 is also electrically connected one for controlling the restraint device of Door Lock, and actuating device 40 is provided with one for the feedback signal interface that brakes, and restraint device is used for forbidding that Door Lock is opened when brake feedback signal not detected.By this kind of mode, the preferred embodiment of the present invention can prevent vehicle in the process of moving, because the maloperation of occupant is by car door opening, and stops the therefore potential safety hazard caused.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
