Abstract

The utility model provides a servo rearview system which is formed by sequentially connecting a vehicle speed and steering wheel rotation angle sensor, a central processing unit, a rearview mirror electronic control unit and a rearview mirror adjusting mechanism. By adopting the servo rearview system, the rearview range can adapt to steering angles of a vehicle, so that road situations behind the rear part and the lateral rear parts of a vehicle can be conveniently observed in the maximum range. The rearview range is remarkably amplified, the tensity of a driver can be reduced, and the driving interestingness and the safety performance are improved.

Description

A kind of servo-actuated back-sight visual system
Technical field
The utility model relates to the vehicle rearview mirror control device.
Background technology
At present a lot of traffic accidents are to exist the blind area to cause by back mirror.Therefore, solving the rear view mirror blind zone problem is the problem that industry is relatively paid close attention to.
The visual field problem of back mirror, just refer to minute surface the scope that can be reflected to.Auto trade comprises about the visual field three elements: the distance of (1) driver's eyes and back mirror; (2) size of back mirror; (3) radius of curvature of back mirror.Have certain relation between these three elements, when the distance of backsight with when measure-alike, the radius of curvature of minute surface is more little, and the visual field of minute surface reflection is just big more.Though the radius of curvature of minute surface low coverage scope more is big more, the deformation of body degree of minute surface reflection simultaneously is also big more, and is also far away more with actual distance, often causes driver's illusion.Therefore, the radius of curvature of minute surface just has a limited field, and the radius of curvature of industry standard regulation outside rear-view mirror is R1200 in addition, and the installation site of car outside rear-view mirror must not exceed then 250 millimeters of automobile outermosts, so the back mirror that former car is joined has the blind area.
According to most drivers' driving habit, when motor turning, often only with the naked eye sweep the outside situation of turning; And more depend on the rear vision area that back mirror provides more, so, for the fixing reflection rear vision area of the common back mirror that is installed on the automobile both sides; When automobile is turned on bend, owing to can't in time see clearly side, back situation, " backsight turning blind area " usually can appear; Side swipe and side are often hit and are all therefore caused, and have greatly threatened the driving safety of vehicle.
Though at present the part vehicle has been equipped with the bicurvature back mirror, also only be that the scope with back mirror enlarges slightly; In addition, though the raising rear vision area that the wide-angle lens that provides on the market, pad pasting mirror can be bigger, because backsight influence the deformation extent increasing, what make that chaufeur can't judge the backsight object really is distance, thus the potential safety hazard of bringing.
In addition, people's the visual field also is to influence one of back mirror visual field problem factor.With simple eye and opinion, the human right and left visual field is approximately 160 degree according to the present mankind's the visual field, and two with looking the scopes that can see about 200 degree, and promptly human eye absolute visual field scope is as shown in Figure 1.As for the visual field of upper and lower, the top is that 50 degree, below are 70 degree, adds up to about 120 degree.When steering vehicle, it is very narrow that the visual field can become.For example, when driving to advance with speed per hour 60 kms, the visual field can reduce to 30 degree, if speed per hour is increased to 100 kms, then can hang down only surplus 10 degree.
Summary of the invention
Not enough to prior art, the utility model proposes a kind of servo-actuated back-sight visual system.
Technical scheme is following: a kind of servo-actuated back-sight visual system is characterized in that this system is connected to form by the speed of a motor vehicle and steering wheel angle sensor, central processing unit, back mirror ECU, back mirror adjusting mechanism successively.
The beneficial effect of the utility model is: the deflection angle of rear vision area and vehicle is adapted, so that the observing the rear, cut the road conditions at rear of maximum range.The remarkable expansion of rear vision area can reduce driver's rate of tension, improves and drives enjoyment and safety performance.
Description of drawings
Fig. 1 is the utility model hardware configuration scheme drawing;
The specific embodiment
Shown in accompanying drawing.A kind of servo-actuated back-sight visual system is connected to form by the speed of a motor vehicle and steering wheel angle sensor 1, central processing unit 2, back mirror ECU 3, back mirror adjusting mechanism 4 successively.
System gets into readiness for action with automotive ignition, when the speed of a motor vehicle greater than setting speed and turn radius during greater than setting value, system start-up.The speed of a motor vehicle and steering wheel angle sensor 1 are given central processing unit 2 with the speed of a motor vehicle and bearing circle rotation amplitude information transfer; After central processing unit 2 is analyzed, send the adjustment instruction, under the effect of back mirror ECU 3; Back mirror adjusting mechanism 4 carries out automatic compensation, thereby enlarges rear vision area; Along with bearing circle rotates to returning positive dirction, back mirror adjusting mechanism 4 progressively returns initial position.The governing speed of back mirror angle is dynamically adjusted with the speed of a motor vehicle and turning amplitude.
The utility model can make the deflection angle of rear vision area and vehicle adapt, so that the observing the rear, cut the road conditions at rear of maximum range.The remarkable expansion of rear vision area can reduce driver's rate of tension, improves and drives enjoyment and safety performance.
