Description
[technical field]
The present invention relates to vehicular automotive electronic control field, more particularly, relate to a kind of for car brakeing auxiliary device.
[background technology]
On aerodynamics, French physician Bel is had to exert the theory complied with and prove: speed and the pressure of air rate are inversely proportional to.That is, air rate is faster, and pressure is less; Air rate is slower, and pressure is larger.The wing of such as aircraft be above in positive parabolical, air-flow is very fast; Level and smooth below, air-flow is comparatively slow, defines wing downforce and is greater than upward pressure, create lift.
Automobile can run into air resistance in the process of moving, and this resistance can be divided into the application force of longitudinal direction, side direction and vertical uplift 3 aspects, and air resistance is directly proportional to the speed of a motor vehicle square, so the speed of a motor vehicle is faster, air resistance is larger.General run of thins, when the speed of a motor vehicle is more than 60km/h, the impact of air resistance on automobile has showed with regard to clearly.If car external form is similar to airfoil cross-section shape, the stream pressure due to vehicle body upper and lower surface in running at high speed is different, below large little above, this difference of pressure will inevitably produce a kind of raising force, and the faster difference of pressure of the speed of a motor vehicle is larger, and raising force is also larger.This raising force is also the one of air resistance, and automotive community is called induced drag, accounts for 7% of car load air resistance, although ratio is less, endangers very large.Other air resistance just consumes the power of car, this resistance not only consumption of power, also can produce the driving safety of supporting force harm car, because when car speed per hour reaches certain numerical value, lift will overcome car weight and upwards be held up by car, decrease the adhesive ability on wheel and ground, make car unstable, cause riding stability to be deteriorated.
In order to reduce the lift that car produces when running at high speed, automobile design teacher except improving in car external form, overall for vehicle body forward downward is tilted and on front-wheel, produces downward pressure, the tailstock is changed into short flat, reduce the negative pressure that posteriorly acts on from roof and prevent from trailing wheel from floating, also below the bumper/spoiler of front end of car, loading onto downward-sloping connecting panel.Connecting panel and vehicle body front valance panel join together, and centre has suitable ventilation inlet and adds air flow degree, and lower car spirit pressure, this connecting panel is called deflecting plate.Cover rear end at car runk and do protrusion like imaging duck tail, form downward application force once by sweeping away the air flow resistance come from roof, this protrusion is called spoiler.The inspiration also having a kind of spoiler people to be subject to aircraft wing produces, be exactly that a parallel plate is at an angle to the horizontal direction installed on the tail end of car, the cross-sectional plane of this parallel plate is identical with the cross-sectional plane of wing, just install conversely, smooth surface upper, parabola under, such car can produce under steam with lift ejusdem generis application force, just direction is contrary, and the power utilizing this downward to offset the lift on vehicle body, thus has ensured the safety of driving.
Vehicle runs into emergency situations emergency braking during when running at high speed, car brakeing is apart from long, and vehicle body stability is not enough, easily the series of problems such as rollover occurs.Existing braking ancillary technique is ABS (Anti-lockBraking System) anti-skid brake system mainly, wheel is sent by by the signal of locking by the sensor be arranged on wheel, controller demand regulator reduces the oil pressure of this wheel brake cylinder, reduce lock torque, after certain hour, recover original oil pressure again, constantly like this circulation (per second reach 5 ~ 10 times), makes wheel be in rotary state all the time and has maximum lock torque.Such brake auxiliary device cost is high, although wheel can be made not skid, stopping distance is of a specified duration for a long time, if there is object in front, not easily escapes danger.
Publication number disclosed in 8 days Augusts in 2012 is the Chinese invention " a kind of Vehicle brake assist system " of 102627099A, the power supply comprising microcontroller and power for whole system, also comprises car speed sensor, brake pedal position sensor, brake pedal angle acceleration sensor, driving circuit, electrical motor, air spoiler and Hall element; Its connection mode is: the input end of microcontroller connects car speed sensor, brake pedal position sensor, brake pedal angular acceleration transducer and Hall element respectively, the mouth of microcontroller is connected with air spoiler by driving circuit, electrical motor successively, and the mouth of electrical motor connects Hall element.This invention adopts the air spoiler on roof to carry out auxiliary braking, effectively can reduce the friction between tire and road surface, and road pavement does not produce destruction and extends the service life of tire.But the air spoiler of this invention is directly connected with electrical motor, the air spoiler being controlled roof by electrical motor realizes closure or openness, air spoiler area of thrust surface under such state are less, the resistance produced under the effect of air-flow is also less, and the effect of car assisted braking is also just not ideal enough.And the present invention controls former and later two spoilers by stepping motor and hydraulic actuating cylinder rise and turn an angle respectively, area of thrust surface are larger, and the resistance that airflow function is produced on spoiler is also larger, can make car brakeing better.
