Specific embodiment
A kind of vehicle blind spot detection of the present invention can be by perceiving with controller in auxiliary one safety pre-warning system of parking
Vehicle running state, it is determined that the mode of operation of one safety pre-warning system.The System Working Principle block diagram shown by Fig. 1,
This early warning system has two kinds of mode of operations：Blind-spot detection pattern and auxiliary mode of parking.When before vehicle to traveling and speed is super
Default valve system work and blind-spot detection pattern are crossed, now first sensor and 3rd sensor work；When vehicle is moveed backward
When work in auxiliary mode of parking, the work of first sensor, second sensor and second sensor.
First, Fig. 2 is referred to when system is in blind-spot detection pattern, first sensor, second sensor work, its inspection
Surveying strategy is：By the relative position for detecting this car and front left side, having front side, left rear side, right lateral side vehicle, judge to have vehicle or
Barrier enters the rearview mirror blind spot region of this car, gives a warning and reminds to this car driver；Judge that this vehicle enters the 3rd
During the blind area of square vehicle, system also can give a warning and remind to this car driver, remind this car driver to sail out of the 3rd as early as possible
The rear view mirror blind zone of square vehicle.
Compared with the present invention, using the various types of vehicles of existing driving blind monitoring technology, institute of the present invention is not had
What is had enters the active forewarning function of the rearview mirror blind spot region of third party's vehicle for this car, such that it is able to a greater degree of
The application level and using effect of driving blind-spot detection technology are improved, the generation of traffic accident is further reduced.
Second, refer to Fig. 3 when system is in and parks auxiliary mode, at this time first sensor, second sensor and
3rd sensor works simultaneously, and its inspection policies is：Automobile front left side, forward right side, left rear side, right lateral side and rear sensor and
3rd sensor works simultaneously, the distance of real-time detection vehicle and surrounding vehicles or barrier, and shows in real time and remind, and helps
Driver completes to park.
Compared with the present invention, existing reverse radar system major part do not have that the present invention has for lateral and
Forward direction radar range finding active forewarning function, and existing radar for backing car technology do not work generally with vehicle forward movement,
Barrier early warning can not be carried out.The auxiliary mode of parking of the system can overcome the above not enough, such that it is able to help to a greater extent
Help driver to complete safety to park, reduce the generation of process accident of parking.
The System Working Principle block diagram shown below by Fig. 1, it is of the invention with reference to the exemplary explanation of Fig. 2 and Fig. 3
All modules and its course of work, the present invention is better understood on to facilitate.
In the middle of this embodiment, safety early warning system is by first sensor, second sensor, 3rd sensor, control
Device, indicator etc. are constituted.
Controller is the core component of safety early warning system, and controller is received and passed from first sensor, second
The signal of sensor, 3rd sensor, alternatively, controller can be communicated with the CAN of vehicle, obtain more vehicles
Status information, in this case, 3rd sensor can be without installing.Controller passes through transducing signal or CAN signal
Determine the mode of operation of system -- blind-spot detection pattern and auxiliary mode of parking.
If being in blind-spot detection pattern, first sensor detects this car and front left side, forward right side, left rear side, right lateral side the
The relative position of tripartite's vehicle, controller can be according to the current driving shape of the signal evaluation of the 3rd sensor of first sensor
State, and the control instruction of response is exported, complete the judgement and output of the early warning information under blind-spot detection pattern；
If in parking auxiliary mode, first sensor, and second sensor detection vehicle and third party's vehicle or barrier
Range information, controller according to the current driving states of the signal evaluation of 3rd sensor, and can export vehicle and surrounding obstacles
The range information of thing, helps driver to complete task of parking.
In addition, for controller, can also set in different modes according to driving states to different assessment knots
Fruit exports corresponding warning level, so more can intuitively differentiate the danger that this vehicle is presently in indicator
Rank size, disposal is moderately treated for driver.The judgment threshold for entering rear view mirror blind zone can also be adjusted, improve this
The actual effect of invention and flexibility.
According to practical application needs, first sensor, second sensor can be set one or more in the present invention,
These sensors are installed at the suitable position of vehicle so as to more effective accurately detection signal.Additionally, in order to improve system
Flexibility, user can by Enabler select to be turned on and off the system or selectively unlocking blind-spot detection module with
Park supplementary module function.
Indicator is the display unit of safety pre-warning system of the present invention, mainly receives the alarm signal of controller or refers to
Order, and shown with certain means, early warning is carried out to this car driver or is referred to or is judged for driver.Display means can
It is various to have, it is described in detail below.
Indicator, it is mounted and the appropriate position of vehicle, such as installed in left and right rearview mirror, or corresponding in-car
The light prompting of appropriate location, or on seat/steering wheel（Vibration prompting）, the display screen of correct position reminds etc. one or more
Early warning alerting pattern.Indicator can also be according to controller to warning level assessment, by indicator to this car provide sound it is big
Small content, prompting device output changes voice frequency size, and light intensity and flicker frequency change, shockproofness, display content color
Deng.
Only with the above-mentioned illustration purpose of the present invention, technical scheme and implementation result, it is not intended to limit the invention, it is all
Within the spirit and principles in the present invention, any modification made, equivalent, improvement, polishing etc., should be included in the present invention
Protection domain within.
