The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, the caution system of a kind of turn inside diameter blind area comprises direction sensor 1, treater 2 and two warning light devices 3,
Described direction sensor 1 is used for gathering in real time the angle of turn of bearing circle, and sends the angle of turn of bearing circle to treater 2;
Described treater 2 is used for calculating according to the angle of turn of the bearing circle that receives the angle of turn of vehicle interior side front-wheel, also is used for sending the order of opening different warning lights to the warning light device 3 of vehicle interior side in real time according to the angle of turn of vehicle interior side front-wheel;
Described warning light device 3 is installed on the rear portion (decide according to vehicle concrete installation site) of vehicle both sides, be used for order unlatching corresponding prompt lamp, project and the corresponding inside rear wheel turning track of inboard Nose Wheel Steering angle according to the unlatching warning light of treater transmission.
Wherein, the process of the angle of turn of described treater 2 calculating vehicle interior side front-wheels is to use the transmitting ratio of the angle of turn of bearing circle divided by vehicle steering mechanism.
Wherein, described treater 2 will judge whether the angle of turn of vehicle interior side front-wheel reaches default minimum angles before warning light device 3 sends the different warning light orders of unlatching, the default the minimum angles whether angle of turn of cooresponding bearing circle reaches.
Wherein, the value of the default minimum angles that described vehicle interior side front-wheel reaches is 14 degree, and the default minimum angles that described bearing circle reaches is different and different according to the transmitting ratio of vehicle steering mechanism.
Wherein, the corresponding relation of the turning track radius of described vehicle interior side trailing wheel and the angle of turn of inboard front-wheel is as follows,
R=L/tanθ
Wherein, R is the turning track radius of vehicle interior side trailing wheel, and L is the wheelbase (being the vertical distance between automobile front-axle and the rear axle) of vehicle, the angle of turn of inboard front-wheel when θ is turning.
Wherein, more than one warning light, the rectangular array arrangement of described warning light are installed on the described warning light device.
Wherein, the quantity of described warning light and the setting angle of each warning light on the warning light device are decided according to vehicle, in addition the setting angle of each warning light with its apart from floor level and want the position in incident point relevant, the position of installation suggestion lamp and angle are to determine according to the point that each warning light will shine on the warning light device, thereby a plurality of warning light can project the turning track of vehicle interior side trailing wheel when lighting jointly.
Wherein, described warning light adopts LED lamp or laser lamp, because the light intensity of LED lamp and laser lamp is big, still can use by day.
Wherein, all be added with lens on described each warning light, the light scioptics that each light source sends are converted into nearly one meter long line, and a plurality of then LED lamps just can be formed a camber line that is similar to automobile inner side trailing wheel track.
Wherein, the default minimum angles that described bearing circle reaches is different and different according to the transmitting ratio of vehicle steering mechanism, and the value of the default minimum angles that described vehicle interior side front-wheel reaches is 14 degree.Because different vehicle transmitting ratio difference, when the angle of turn of vehicle interior side front-wheel reaches identical angle, the angle of turn of bearing circle can be different, so when the default minimum angles of vehicle interior side front-wheel was identical, the default minimum angles of the bearing circle of different automobile types was different.
When direction sensor detects angle that bearing circle turns over and reaches default minimum angles (angle of turn that is the vehicle interior side front-wheel reaches 14 degree), direction sensor is then constantly gathered the angle of turn of bearing circle in the turn inside diameter process, and send treater in real time to, calculate the angle of turn of the inboard front-wheel of Ackermann steer angle for treater.
Treater calculates the angle of turn of vehicle interior side front-wheel in real time according to the angle of turn of bearing circle, and to the inside warning light device sends the order of opening different warning lights in real time; The warning light device is opened different warning lights to project the turning track of inside rear wheel, to warn pedestrian or other vehicles on this vehicle next door according to the order that receives in the turn inside diameter process.
Fig. 2 is the scheme drawing in the caution zone that turn inside diameter projects among the embodiment 1, when the inboard front-wheel of vehicle 201 is turned with the steering angle of 14 degree in the present embodiment, the direction sensor angle of turn of bearing circle at this moment sends treater to, treater calculates the steering angle of vehicle interior side front-wheel according to the angle of turn of bearing circle, and send the order of opening the warning light device to the warning light device according to the steering angle of inboard front-wheel, the warning light of being responsible for this track on the warning light device all lights, every warning light projects nearly one meter long line segment, a plurality of then warning lights just can be formed first camber line 202 that is similar to automobile inner side trailing wheel track, (near a side of car body) promptly is the hazardous location in first camber line 202, and first camber line 202 outer (away from a side of car body) is a safety zone.If vehicle 201 is to turn with constant deflection angle, in the present embodiment 14 degree, all warning lights of then being responsible for the cooresponding track camber line of projection 14 degree deflection angles on the warning light device are light yellow always; If the deflection angle of vehicle 201 becomes 20 degree, all warning lights of then being responsible for the cooresponding track camber line of projection 20 degree deflection angles light, and all warning lights of being responsible for the cooresponding track camber line of projection 14 degree deflection angles extinguish.
Wherein, each point on first camber line 202 is represented the mid point of the line segment that each warning light projects, and the straight line line segment that warning light projects is tangent at this some place and first camber line 202.
Fig. 3 is the scheme drawing in the caution zone that turn inside diameter projects among the embodiment 2, work as the deflection angle of vehicle interior side front-wheel in the present embodiment at [14 °, 18 °) between the time vehicle interior side trailing wheel that projects turning track be first camber line 202, when the vehicle interior side front wheel steering angle at [18 °, 22 °) between the time vehicle interior side trailing wheel that projects turning track be second camber line 203, afterwards; Can project the camber line of 8 vehicle interior side trailing wheel tracks in the present embodiment altogether.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
