Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in figure 1, the utility model provides a kind of multi-functional prompt system of invisible road conditions in front of front truck, installation
In on the oversize vehicles such as bus, lorry, including image acquisition device 110, display screen 120 and controller 130.Controller 130
It is connected respectively with image acquisition device 110 and display screen 120, controller 130 is set in the car.
Described image collector 110 is arranged on the front of vehicle, for collection vehicle forward image.Described image collector
110 use high-definition camera.Transparent protective cover 111 is installed outside image acquisition device 110, for entering to image acquisition device 110
Row protection, rainwater causes to damage to image acquisition device 110 when preventing from raining, and also avoids the sandstone that road surface is splashed to image acquisition device
110 cause to beat shock.
As shown in figure 3, described image collector 110 is arranged on head, formula image acquisition device 110 can be around horizontal axis
Rotation, and by motor drive can adjusting pitch angle, and control direction and the car of the axis of image acquisition device 110
The angle of direction of advance is in the range of ± 5 °.
Display screen 120 is arranged on the rear of vehicle, is capable of the figure of the collection of real-time display image acquisition device 110 on a display screen
Picture, watched for the vehicle driver at rear, so as to understand the situation of front truck road ahead, especially junction ahead traffic lights
Situation.Meanwhile controller 130 can to image acquisition device 110 gather image analyze, judge front whether have vehicle with
And whether front is in red light phase, and, front vehicle driver is carried out further with text importing on the display screen 120
Remind.
Be also equipped with controlling switch 140 in the car, it is connected with controller 130, can control whole system unlatching or
Close, when vehicle enters mountain road or other complicated roads, opened by driver；It can close unwanted when, subtract
Few energy consumption.
On the car body of the left and right sides of vehicle, row's distance measurement sensing is provided with along its length from headstock to the tailstock
The distance between device 150, two neighboring distance measurement sensor 150 is equal.As a kind of preferable, two neighboring distance measurement
The distance between sensor 150 is 5-10cm.
Vehicle distances this vehicle of the left and right sides can be measured using the distance measurement sensor 150 positioned at car body both sides
Distance, while the relative pace with this vehicle of vehicle that the left and right sides can also be measured.As shown in figure 3, for example exist
There is the vehicle in a traveling in the left-hand lane of this vehicle, by the array pitch positioned at this vehicle left side from detection sensor
150 can measure the distance H of this vehicle of vehicle distances in left-hand lane.Simultaneously, moreover it is possible to measure vehicle phase in left-hand lane
Pace pair with this vehicle.A certain moment, left side vehicle are located at location A, and after a period of time, left side vehicle has driven to B
Position, now, the change that the position of the distance measurement sensor 150 of left side vehicle also occurs can be detected, according to two positions
The distance between detection sensor 150 that front end two can detect left side vehicle when putting, divided by time can just obtain
The relative pace v with this vehicle of vehicle in left-hand lane.In addition, a left side can also be obtained by distance measurement sensor 150
Distance h of the tailstock of side vehicle apart from this car tailstock.
Tailstock distance sheet of the vehicle with respect to the pace v with this vehicle, and left side vehicle on left-hand lane is obtained
After two parameters of distance h of the car tailstock, controller 130 can be handled the two parameters, then whether remind front vehicle
It is adapted to overtake other vehicles from left side.
When controller 130 is judgedAnd meet v ＞ 0, then can in the display of display screen 120 during h ＞ 2
To be overtaken other vehicles from left side, otherwise display is forbidden overtaking other vehicles from left side.
Likewise, by distance measurement sensor 150 can obtain vehicle in right-hand lane it is relative with before this vehicle
Enter speed v0, and right side vehicle the tailstock apart from this car tailstock distance h0, controller 130, which is understood, be handled the two parameters,
Then front vehicle is reminded to be overtaken other vehicles if appropriate for from right side.
, then can be from the display of display screen 120 during h ＞ 4 when controller 130 judges 5h+2v ＞ 0 and meets v ＞ 0
Right side is overtaken other vehicles, and otherwise display is forbidden overtaking other vehicles from right side.
By reminding front vehicle, if it can be overtaken other vehicles, so as to effectively avoid front vehicle when surmounting this car,
Because the visual field kept off, blindly overtake other vehicles and caused by traffic accident.
The utility model additionally provides one kind and overtaken other vehicles method for early warning, it is therefore an objective to pair is collided during to surmounting front truck with front truck
Risk carries out early warning.
Rear car comes into effect passing behavior at the t=0 moment, rear car using laterally accelerate overtake other vehicles before speed adjustment time as
tadj, the type that rear car collides with front truck car is vehicle oblique collision or vehicle rear-end collision collision, it is assumed that front truck is on former track
Remain a constant speed traveling, that is, meets that condition front truck lateral and longitudinal acceleration is 0.When rear car is with certain transverse acceleration
When passing through front truck left side boundary line, angle point front truck collides before the rear car right side.Rear car elapsed time tc+tadjAfterwards, angle point is firm before the right side
Pass through front truck left side boundary line well, define tc+tadjThe time of the point of impingement is reached for rear car.
As t ＜ tadjWhen, if passing behavior is still not carried out in rear car, rear-end impact easily occurs with front truck；When in tadj＜ t ＜
tc+tadjWhen, if rear car implements passing behavior, oblique collision easily occurs with front truck front truck.Work as t=tc+tadjWhen, before the rear car right side
The lateral displacement of angle point is
Wherein, y0(t) it is rear car barycenter horizontal line displacement, x0(t) it is rear car length travel, w0For rear vehicle-width.
Analyze the movement relation between vehicle in the case of this, the safe early warning condition of rear car and front truck is：
x0(t) ＜ x1(t)-l1-w0sinθ(t)
Wherein, x1(t) it is front truck length travel, θ (t) is deflection.l1For front truck length, it is on passing time
Function.
Last w in above formula0Being introduced into of sin θ (t) can ensure that in whole overtaking process that angle point is with before before the right side of rear car
Any type of collision does not occur for the tailstock of car.In view of the corresponding period is t=t when θ (t) obtains maximum with sin θ (t)c
+tadj, early-warning conditions can be simplified to
x0(t) ＜ x1(t)-l0-max(sinθ(t))
Make Sr(t)=x1(t)-l1-x0(t)
As t ∈ [0, tc+tadj], as long as ensuring Sr(t) ＞ 0, would not be collided when rear car surmounts front truck, i.e.,
When meeting above formula condition, controller 130 send the signal that can overtake other vehicles to display screen 120 prompt rear car this
When can be overtaken other vehicles.Otherwise no overtaking for prompting.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
