Technical field
The present invention relates to a kind of mechano-electronic control system, more particularly, relate to a kind of automobile brake ancillary system.
Background technology
Along with the continuous development of auto-industry, all kinds of automobiles all are furnished with BAS.The BAS of transmission generally adopts mechanical device to wheel generation effect, all adopts friction and the friction between tire and the road surface between brake disc and the friction lining to make car retardation.Have with its shortcoming of this brake mode: 1, principle is single, and stopping distance is longer; 2, each catcher all can produce violent friction with the road surface, makes Tyte Wear bigger, has shortened the service life of tire, also is simultaneously that the physical construction of brake system is worn.
Chinese patent ZL200810072818.9, Granted publication day is on July 30th, 2008, invention and created name is: a kind of automobile emergency braking device; This device comprises the fixed mount that is fixedly installed in bottom behind the automobile, and drag anchor formula drg, drag anchor formula drg are provided with drag anchor formula drg main body; On the drag anchor formula drg main body polylith braking composite material plate is installed, and is provided with telescopic braking nail, the braking nail is connected with braking nail jacking system; Drag anchor formula drg is equipped with drag anchor formula drg jacking system, and drag anchor formula drg main body is provided with stage clip, and polylith antifriction, high-temperature resistant braking composite panel and telescopic braking nail are installed; Though should invention use electric circuit control, more can practice thrift braking time, effectively increase friction; And give full play to effective brake action, but this device has increased the curb mass of automobile greatly, has increased oil consumption; Therefore and be not suitable for the automobile brake ancillary system and road pavement produced destructive the damage when this device used.
Summary of the invention
The technical matters that the present invention solved is to provide a kind of road pavement in use not produce and destroys and automobile brake ancillary system simple in structure, practical, good stability.
For solving above technical matters, the present invention is achieved through following technical scheme.
A kind of automobile brake ancillary system; Comprise microcontroller and be the power supply of total system power supply, it also comprises car speed sensor, brake pedal position sensor, brake pedal angular acceleration transducer, driving circuit, electrical motor, air spoiler and Hall element; Its connection mode is: the input end of said microcontroller connects car speed sensor, brake pedal position sensor, brake pedal angular acceleration transducer and Hall element respectively; The mouth of said microcontroller links to each other with air spoiler through driving circuit, electrical motor successively, and the mouth of said electrical motor connects Hall element.
Adopt technical scheme provided by the invention, compare, have following remarkable result with existing known technology:
(1) owing to adopt Hall step-by-step counting mode to control, rely on advanced software algorithm to come the positioning control air spoiler, the air spoiler long-play can not produce accumulated error, so system's stable and reliable operation.
(2) this automobile brake ancillary system adopts the air spoiler on the roof to carry out auxiliary braking, can reduce the friction between tire and the road surface effectively, and road pavement does not produce the service life of destroying and having prolonged tire.
Description of drawings
Fig. 1 is the functional-block diagram of automobile brake ancillary system of the present invention.
Scheme drawing when Fig. 2 is in closure state for air spoiler on roof.
Scheme drawing when Fig. 3 is in opening for air spoiler on roof.
Among the figure: 1, vehicle dormer window; 2, car roof; 3, air spoiler; 4, air spoiler hugging.
The specific embodiment
For further understanding content of the present invention, the present invention is described further below in conjunction with accompanying drawing.
As shown in Figure 1, this automobile brake ancillary system is made up of microcontroller, power supply, driving circuit, electrical motor, brake pedal angular acceleration transducer, brake pedal position sensor, car speed sensor, Hall element and air spoiler.Connection mode with upper-part can be known from Fig. 1: the input end of said microcontroller connects car speed sensor, brake pedal position sensor, brake pedal angular acceleration transducer and Hall element respectively; The mouth of said microcontroller links to each other with driving circuit; The mouth of said driving circuit links to each other with electrical motor, and the mouth of said electrical motor links to each other with Hall element with air spoiler respectively.
Like Fig. 2, shown in Figure 3, air spoiler 3 is positioned on the car roof 2 and laterally arranges with vehicle dormer window 1; When closure state, air spoiler 3 is embedded among the air spoiler hugging 4.
Below in conjunction with embodiment the present invention is done further description.
During this automobile brake ancillary system auxiliary braking, power supply is that total system is supplied power; In vehicle traveling process, when car speed sensor recorded moving velocity and reaches pre-set velocity, car speed sensor was input to microcontroller with GES, handled the back through microcontroller and opened total system.When emergency braking; The brake pedal angular acceleration transducer record the brake pedal angular acceleration signal and be entered into handle on the microcontroller after; Microcontroller is delivered to control signal in the driving circuit again; Unlatching through driving circuit may command electrical motor or stop, thereby the aperture of control air spoiler.Brake pedal position sensor is used to detect the position of brake pedal, and detected signal is delivered on the microcontroller handle the switching of control air spoiler.
In above-mentioned automobile brake ancillary system, after opening total system, during the chaufeur emergency braking; When in a single day the angular acceleration of brake pedal is higher than preset value; Microcontroller is reacted rapidly, and control signal is delivered to driving circuit, the unlatching at control motor; In the extremely short time, make air spoiler reach desirable aperture, with car assisted braking.When chaufeur lifts brake pedal to initial position; The signal that brake pedal position sensor is got back to initial position with brake pedal is input to microcontroller; Microcontroller is reacted rapidly; Control signal is delivered to driving circuit, the control motor antiport, the drive air spoiler returns initial position.
In above-mentioned automobile brake ancillary system; The said sensor that is used to detect motorrun state is a Hall element; And Hall element is through inductive impulse signal detection motorrun state; And detection signal sent into microcontroller is counted and juggling, and then judge the air spoiler present position; For the opening and closing of control air spoiler, the revolution of Hall element calculating motor is installed, i.e. the pulse count of Hall element on electrical motor.When electrical motor rotated, Hall element detected impulse singla; When the electrical motor stall, Hall element output unmodified high potential or active potential are input to the signal that obtains in the microcontroller and handle, thus the unlatching of control air spoiler or close.
