Description
Technical field
The present invention relates to a kind of automobile-use optical viewing arrangement is and in particular to a kind of extension outside rear-view mirror for vehicle visual angle
Method and device.
Background technology
Vehicle mirrors provide the vehicle-state at rear, side rear in vehicle traveling for driver, including in-car backsight
Mirror, and the exterior mirror on both sides.Generally, room mirror observes the state after car, and the exterior mirror on both sides is used for observing
The state of both sides, is also used for reversing warehouse-in, side parking etc. simultaneously.In the process of moving, if desired lane change, then need advance observations
Front vehicle and side vehicle-state, but almost parallel vehicle by its vehicle body is then rearview mirror, rearview mirror can't see(As figure
3), the region that this be can't see is referred to as blind area, and blind area easily leads to the generation of traffic accident.Additionally, vehicle is in no signal lamp
When guiding is turned round, driver can't see vehicle condition on road intersection, the vehicle particularly travelling in the same direction(As Fig. 6), also easily
Lead to accident.In order to reduce blind area, traditional rearview mirror is changed to double curvature rearview mirror or increases the miniature of wide-angle by some vehicles
Rearview mirror, to see the broader position of vehicle body side, reducing rearview mirror visual angle dead band, allowing driver have broader visual angle.Though
So micro-rearview mirror can see do not have thing in blind area, but because it is too little, the scenery that is imaged can be caused little and image fault is serious;
When adjusting rearview mirror primary mirror angle, micro-rearview mirror can be followed and adjust together, lead to its function reduction.After hyperbolicity
Although visor increases visual angle, effect is bad, and blind area is also very big.
Content of the invention
It is an object of the invention to provide a kind of method and device at extension outside rear-view mirror for vehicle visual angle, this apparatus and method
Driver's seat can be expanded according to the angle of the transport condition self-adaptative adjustment auxiliary mirror of vehicle, reduce blind area.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of device at extension outside rear-view mirror for vehicle visual angle, including:
Auxiliary mirror, is placed in above outside rear-view mirror for vehicle;
Sensor group, for the motor message of collection vehicle;
Controller, by the rotation of auxiliary mirror described in transmission actuating mechanism controls, described controller receives sensing
The data of device group collection, and vehicle running state is judged according to the data of collection, generate control instruction and control described transmission execution
Mechanism rotates, thus driving the rotation of auxiliary mirror, to reduce vehicle visual angle blind zone.
Further scheme is, described sensor group includes angular-rate sensor, three dimension acceleration sensor, is used for adopting
The angular velocity signal of collection vehicle, three-dimensional acceleration signal.
Further scheme is, described transmission executing agency includes stepper motor, and this stepper motor passes through fixed mechanism
It is fixed on outside rear-view mirror for vehicle shell, Stability Analysis of Structures is reliable.
Further scheme is, described controller and sensor group are placed in outside rear-view mirror for vehicle shell and rear view mirror lens
In the cavity being formed, decrease the volume of whole device, it also avoid sensor group and ectocine that controller is subject to is it is ensured that survey
The amount degree of accuracy.
Further scheme is, described controller is also bonded with control, in order to arrange auxiliary mirror and vehicle
The angle of outside rear-view mirror.
The present invention also provides a kind of device using above-mentioned extension outside rear-view mirror for vehicle visual angle to be extended the outer backsight of vehicle
The method at mirror visual angle, comprises the steps:
By the angular velocity signal of sensor group collection vehicle, three-dimensional acceleration signal;
Vehicle running state is judged according to the above-mentioned data of sensor group collection, and according to the corresponding life of this transport condition output
Order, controls transmission executing agency to be rotated, transmission executing agency drives auxiliary mirror rotation, thus it is blind to reduce vehicle visual angle
Area.
Corresponding speed is obtained according to the angular velocity signal of sensor group collection, three-dimensional acceleration signal, thus judges car
Transport condition, specific method of discrimination is:If angular speed is ω, vertical direction acceleration is αz, vertical speed is Vz,
Direction of advance acceleration is αX, direction of advance speed is vxT (), horizontal displacement acceleration is αy, horizontal displacement speed is vy(t);
