Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vehicle in the utility model, is also the structural representation of a kind of emergency brake of vehicle auxiliary device in the utility model simultaneously.
The name that in figure, each Reference numeral is corresponding is called: 1 car body, 2 front vehicle wheels, 3 rear wheels, 4 automobile brake pedals, 5 vehicle computers, 6 jetting system, 61 gas ejection ports, 7 rang sensors, 8 acceleration pick-ups.
The specific embodiment
In the utility model, a kind of vehicle embodiment as shown in Figure 1, comprises car body 1, front vehicle wheel 2, rear wheel 3, automobile brake pedal 4 and vehicle computer 5(automobile ECU), also comprise emergency brake of vehicle auxiliary device.
Described emergency brake of vehicle auxiliary device comprise there is the jetting system 6 of gas ejection ports 61, for the source of the gas to jetting system 6 air feed with control the control setup that described source of the gas is opened.Wherein jetting system 6 is provided with two, be fixed on symmetrically on the vehicle body at rear wheel 3 rears, and injection orifice arranges upward along the Width of vehicle.What source of the gas adopted is one widely used air-cushion inflator in air bag system, comprises firing unit, medicament and air extractor duct, and after firing unit igniting, medicament can produce a large amount of nitrogen moment and spray from air extractor duct.In the present embodiment, air-cushion inflator is arranged in car body 1, and air extractor duct is communicated with the injection orifice of jetting system 6, and its firing unit is connected with vehicle computer 5.Described control setup comprises and judges the pressure sensor of the action of brake system for detection of the trampling pressure of automobile brake pedal 4, judges at the acceleration/accel of above-below direction for detection of the rang sensor 7 of vehicle and vehicle front object distance with for detection of car body 1 whether vehicle starts to occur the acceleration pick-up 8 of seriously nodding, wherein pressure sensor is arranged on automobile brake pedal 4, and described pressure sensor, rang sensor 7 and acceleration pick-up 8 all communicate to connect with the vehicle computer 5 of vehicle.The firing unit control linkage of vehicle computer 5 and air-cushion inflator, according to the unlocking condition of setting, after each sensor satisfies condition, vehicle computer 5 is controlling point firearm igniting, make air-cushion inflator moment produce a large amount of high pressure gas, from injection orifice ejection, rely on recoil to produce enough large opposition.Certainly, in other embodiments, the action of motor vehicle braking system also can adopt other sensors to detect.
Above-mentioned emergency brake of vehicle auxiliary device is installed on the tailstock, when obstacle appears in front in high vehicle speeds, objects such as vehicle and while there is risk of collision, chaufeur will be stepped on automobile brake pedal 4, now rang sensor 7 can detect the distance of the object such as vehicle and obstacle or vehicle and pass to vehicle computer 5, if this distance meets setting value, and what pressure sensor detected trample pressure meets setting value, acceleration pick-up 8 also determines automobile and has started to occur serious nodding, vehicle computer 5 is lighted a fire controlling point firearm, injection orifice ejection gas, rely on recoil to prevent that headstock from sinking, alleviate or avoid vehicle occur nodding phenomenon and occur the phenomenon that rear-wheel braking force declines.If the speed of a motor vehicle is lower, front obstacle is far away or clear, vehicle can be avoided occurring colliding by normal brake application, and the detected value of each sensor can not meet entry condition, and vehicle computer 5 can not send ignition order to firing unit, guarantees normal vehicle operation.
Emergency brake of vehicle auxiliary device in the embodiment that in the utility model, emergency brake of vehicle auxiliary device embodiment is above-mentioned a kind of vehicle repeats no more herein.
In the above-described embodiments, jetting system 6 be arranged on the car body 1 at rear wheel 3 rears and injection orifice towards setting, in other embodiments, jetting system 6 also can be arranged on the car body 1 in front vehicle wheel 2 fronts with injection orifice form down, and its quantity also can be one, or more than three.In addition, what in above-described embodiment, source of the gas adopted is air-cushion inflator, and control setup comprises the pressure sensor, acceleration pick-up 8 and the rang sensor 7 that communicate to connect with vehicle computer 5, in other embodiments, source of the gas also can adopt other forms, the source of the gas of for example compressed air type, and control setup also can adopt other forms, the for example vehicle collision avoidance system of current comparative maturity is controlled source of the gas and is opened, or adopts manually operated valve etc. in the time there is risk of collision.
