Description
Technical field
The utility model relates to vehicle safety technical field, particularly a kind of anti-system that knocks into the back of vehicle.
Background technology
If road conditions complexity, can often there is the emergency case such as sudden stop, deceleration in vehicle in driving way, very easily causes the rear-end collision of vehicle below to send; In addition,, if the chaufeur technology of vehicle is not good, when closely with car, also very easily cause the collision of two vehicles below.Rear-end collision weight causes the damage of vehicle, causes economic loss; Heavy can cause an instantaneous deceleration/decel of being collided, the force of inertia combined action of this deceleration/decel and chaufeur head, make chaufeur neck can produce an action of hitting suddenly as whip, cause whiplass, i.e. " whiplash injury ", this injury is not fatal, but after wound, the process of rehabilitation is very complicated, very long, some or even the permanent injury can not be cured.
Therefore,, in order to prevent the generation of rear-end collision, need to take safety method or early warning prevention.For example, the sensors such as radar, pick up camera, laser are set in the front of vehicle, avoid vehicle and preceding vehicle generation rear-end collision, but cannot avoid " by knocking into the back ".
For the situation of " by knocking into the back ", generally adopt passive protection or give warning in advance.Wherein, passive protection is that headrest is set in vehicle, while generation when knocking into the back; the chaufeur head headrest that clashes, and then trigger headrest and move forward, the impact of knocking into the back to chaufeur reduced; or Mobile chair is set in vehicle, while generation when knocking into the back, after triggering seat, moves.Giving warning in advance is to monitor the spacing of vehicle below, and in the time that spacing reaches danger range, the warning light that starts this car vehicle is pointed out the chaufeur of vehicle below.
At present; the problem that prior art exists is: for first kind of way; while generation when knocking into the back; when chaufeur clashes passive protection headrest or seat; just by the action of mechanical device trigger protection (moving after headrest reach or seat); require chaufeur enough large to the impulsive force of seat, and chaufeur now does not very likely feel well or has come to harm, and cannot effectively protect completely.For second method, if while carrying out early warning by being arranged on the pressure sensor of the vehicle tailstock, need vehicle to knock into the back and just make corresponding actions, very not in time, if by being arranged on the equipment such as the laser of the vehicle tailstock, can only detect the spacing of vehicle, if the speed of a motor vehicle of vehicle is too fast, also there will be warning phenomenon not in time below.

Elaborate the specific works process of the anti-system that knocks into the back of vehicle below.
In the driving process of vehicle, prior-warning device 6 and fender guard 5 can be taked different early warning and/or safety method to vehicle according to the time T that for example knocked into the back of the anti-early warning information that knocks into the back in controller 4.Particularly, the time T that knocked into the back can be divided into 3 intervals according to car to car impact degree of risk, using Tmin, Tmid, Tmax as the event horizon value that knocked into the back.Wherein, knocked into the back event horizon value Tmin, Tmid, Tmax is relevant with the speed information of vehicle, along with the speed of a motor vehicle increase knocked into the back time critical values Tmin, Tmid, Tmax can correspondingly increase, and thus, guarantees that two car chaufeurs have enough reactions and opening time.
More specifically, in the time of T>Tmax, controller 4 sends normal signal, that is to say, now vehicle is not taked to early warning and safety method.
When T ∈ (Tmid, Tmax] time, controller 4 sends the first anti-early warning information that knocks into the back, now prior-warning device 6 carries out warning prompt to vehicle, fender guard 5 is not taked safety method.Particularly, show flicker warning tag in read-out 64, loud speaker 61 is reminded every 1 second " dripping " acoustic alarm, and brake lamp 62 is lighted, and above action continued until the time
When T ∈ (Tmin, Tmid] time, controller 4 sends the second anti-early warning information that knocks into the back, now prior-warning device 6 carries out warning prompt to vehicle, fender guard 5 is not taked safety method.Particularly, show flicker warning tag in read-out 64, loud speaker 61 is every 0.5 second " a dripping " sound alarm and reminding, and two flashing lights 63 are lighted, and above action continued until the time
When T ∈ (0, Tmin] time, controller 4 sends the 3rd anti-early warning information that knocks into the back, now prior-warning device 6 carries out warning prompt to vehicle, and fender guard 5 is taked safety method.Particularly, in read-out 64, show flicker warning tag, loud speaker 61 is every 0.5 second " a dripping " sound alarm and reminding, two flashing lights 63 are lighted, and the headrest 51 that motor 52 is controlled on seat moves forward to chaufeur head, safety belt controller 54 is controlled safety strap 53 and is tied tight, and above action continued until the time
The anti-system that knocks into the back of the vehicle of the utility model embodiment; in the time vehicle being detected by rear-end impact, by the co-ordination of prior-warning device and fender guard, can be in effectively protecting chaufeur; point out in time rear car vehicle, thereby effectively prevented vehicle rear-end collision.
