301, the forward sight camera 301, to judge the lane of road ahead, and lane position signal is transmitted towards vehicle front
To active safety domain controller 3.Therefore, utilization orientation disk rotary angle transmitter 101, yaw angle transducer, forward sight camera 301 etc.
Multiple sensors for being arranged on vehicle body can obtain vehicle travel condition information, and determine that vehicle is in cornering mode, reversing mould
Formula or lane change pattern.The controller 4 is configured to be in the cornering mode, reversing mode or lane change pattern in the vehicle
When, should adjusting for the outside rear-view mirror 6 is determined according to rotation information of the spatial positional information in the car of eyes 5 and steering wheel etc.
Angle.Also, controller 4 is configured to the outside rear-view mirror 6 at the end of the cornering mode, reversing mode or lane change pattern
Angle return to the angle before the cornering mode, reversing mode or lane change pattern terminate.
Further, the angle of 4 pairs of the controller outside rear-view mirror 6 carries out adjusting or being spaced scheduled time progress in real time
Regulation.Therefore, a display pattern is provided with the central control board of vehicle body.The display pattern is used to show the vehicle
Current driving pattern and mode that the angle of the outside rear-view mirror 6 is adjusted.The mode includes manual regulative mode
With automatically adjust mode.The angle that the manual regulative mode is configured to receive the outside rear-view mirror 6 being manually entered is adjusted
The time interval of section.And the mode that automatically adjusts is configured to enter the angle of the outside rear-view mirror 6 according to prefixed time interval
Row regulation.Therefore, controller 4 can enter between-line spacing or in real time regulation according to the demand of driver to outside rear-view mirror 6.In car
On the central control board of body or car door is easy to also set up a shift knob 10 at driver's operation.The shift knob 10 is used for
The instruction that the angle of the outside rear-view mirror 6 is adjusted is sent to the controller 4.
Further, judge outside rear-view mirror 6 angle whether meet the best angle in the Current observation visual field method it is as follows.
The present invention is provided with memory module 11.Memory module 11 is used to store in certain predetermined space of the vehicle corresponding to any position
The outside rear-view mirror 6 with optimal observation scope angle information, i.e. best angle.Controller 4 is according to the locus of eyes 5
Information determines the best angle of the current outside rear-view mirror 6 of outside rear-view mirror 6.And the angle residing for current outside rear-view mirror 6 is set to work as anterior angle
Degree.When the difference of best angle and current angular is not higher than a preset value, then the angle not to the outside rear-view mirror 6 is adjusted
Section；And when the difference is higher than the preset value, then the current angular of outside rear-view mirror 6 is adjusted to best angle by controller 4.
As shown in Fig. 2 referring also to Fig. 3.Transfer mode of the various types of signal in outer door mirror angle adjustment system is as follows.
The present invention obtains vehicle travel condition information using multiple sensors for being arranged on vehicle body.The direction set on steering wheel for vehicle
Disk rotary angle transmitter 101, the angular signal for detecting steering wheel, obtains the angle of steering wheel current operation.The yaw of vehicle
Yaw angle signal is delivered to safety air sac controller 2 by angle transducer.Forward sight camera 301 judges front road towards vehicle front
The lane on road, and lane position signal is passed into active safety domain controller 3.The angular signal, yaw angle letter
Number, the lane position signal the dynamic domain controller 1 of vehicle body is sent to by Flexray or CAN respectively.Vehicle body dynamic domain
Controller 1 calculates the travel condition information of car, such as state of rolling backward, forward travel state, steering according to the status signal of these vehicles
State, changing Lane state etc..
Image acquiring device 7 and the position apart from acquisition module 8 (referring to Fig. 3) measurement driver's eyes relative to camera
And the position in vehicle space.Behind the locus in the car that driver's eyes are determined, driver's eyes phase can be obtained
The field of view information to rearview mirror is seen for the spatial positional information of rearview mirror, i.e. acquisition driver's eyes.And by the driving of acquisition
The spatial positional information of member's eyes is sent to active safety domain controller 3 by Flexray or CAN.
Vehicle body dynamic domain controller 1 will calculate obtained driving states information and be sent to master by Flexray or CAN
Move safe domain controller 3.Active safety domain controller 3 is calculated according to the travel condition information and the spatial positional information
Rearview mirror direction adjusts data, to cause rearview mirror to obtain current human eye most after being adjusted according to the rearview mirror bearing data
The good visual field.For example, when the travel condition information is reversing, the direction of the rearview mirror adjusts regarding to the driver's eyes
Open country is clearly seen parking stall line and spacing mark.For example, the travel condition information is changing Lane state, the side of the rearview mirror
The visual field for turning to lane change completely can be realized to regulation to driver.
Controller 4 receives the rearview mirror direction transmitted by Flexray or CAN and adjusts data and judged.When
The rearview mirror direction regulation data are not more than predetermined value, then the attonity of controller 4, it is believed that now mirror field of view is most
The good visual field；When the rearview mirror direction, regulation data are more than predetermined value, then the controller 4 sends movement to door module 401 and referred to
Order so that door module 401 adjusts data control rearview mirror according to rearview mirror direction and moved.
So far, although those skilled in the art will appreciate that detailed herein have shown and described multiple showing for the present invention
Example property embodiment, still, still can be direct according to present disclosure without departing from the spirit and scope of the present invention
It is determined that or deriving many other variations or modifications for meeting the principle of the invention.Therefore, the scope of the present invention is understood that and recognized
It is set to and covers other all these variations or modifications.
