Description
Technical field
The utility model relates to a kind of ancillary system, and particularly one is driven ancillary system.
Background technology
In the process driven a car, when meeting front and having an obstacle, driver usually rely on driving experience judge preceding object thing whether by.For lacking the chaufeur of posture experience, usually judge inaccurate, cause automobile when limited road cannot judge no can safely through or enter, or be not easy when parking to judge that whether vehicle body parallel with parking lattice both sides, cause the generation of scratching, even cause traffic accident.Therefore, need exploitation one automatically to start and comparatively accurately judge the accessory equipment of vehicle body and the spacing of contiguous thing.
Summary of the invention
The purpose of this utility model is the defect in order to overcome above-mentioned background technology, provides one to drive ancillary system.
One is driven ancillary system, comprises being arranged on the laser transimitter below vehicle sided mirror unit, the controller be connected with described laser transimitter and input end and connecting automobile bus, and mouth connects the bus transceiver of described controller; Described bus transceiver mouth comprises automobile gears signal output part and vehicle speed signal mouth, the control output end that described controller comprises the described automobile gears collection terminal be connected with described automobile gears signal output part, the vehicle speed signal collection terminal be connected with described vehicle speed signal mouth and connects described laser transimitter.
Further, described laser transimitter comprises front emission lamp and rear emission lamp; Described control output end comprises the headlight control end connecting front emission lamp and the back light control end being connected rear emission lamp.
Further, the master cock of the described controller of a connection is also comprised.
Further, the light that described laser transmitter projects goes out is at the yi word pattern light for being parallel to automobile side, and the distance of simultaneously light projection on the ground and vehicle body side is at least suitable with the width of back mirror.
One of the present utility model drives ancillary system by arranging laser transimitter in car both sides, and automatically open laser transimitter when needs, project the yi word pattern linear laser adapted with vehicle on the ground, for chaufeur provides vehicle position information intuitively, facilitate chaufeur in the driving of narrow section or reversing.

Fig. 1 is that the ancillary system in the utility model embodiment one uses schematic diagram.
Fig. 2 is the structural principle schematic diagram of the laser transimitter in the utility model embodiment one.
Fig. 3 is the circuit of auxiliary system principle schematic in the utility model embodiment one.
Detailed description of the invention
In order to allow those skilled in the art more understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, ancillary system of driving of the present utility model is further described.
One is driven ancillary system, comprises being arranged on the laser transimitter 1 below vehicle sided mirror unit, the controller 3 be connected with described laser transimitter 1 and input end and connecting automobile bus, and mouth connects the bus transceiver 2 of described controller 3.
In laser transimitter 1, as depicted in figs. 1 and 2, it is installed on the lower edge of vehicle mirrors, the light that laser transimitter 1 emits is the yi word pattern linear laser being parallel to automobile side, the vertical distance of the projection of the linear light emitted when the laser transimitter 1 of automobile both sides on ground and vehicle body side is at least equivalent to the width of back mirror, effectively ensure obstacle can not scratching to vehicle body and back mirror.Laser transimitter 1 and back mirror can design for integral type, also can by mounting bracket on back mirror, and laser transimitter 1 is fixed on support and realizes.
Excellent
choosingground, laser transimitter 1 at least comprises the one in front emission lamp 11 and rear emission lamp 12, front emission lamp 11 for when automobile advances to the auxiliary judgment of automobile position, then emission lamp 12 is for the auxiliary judgment when car reversed to automobile position.Front emission lamp 11 and rear emission lamp 12 can be opened simultaneously or open as required.
In order to make laser transimitter 1 automatically open when needs, automatically close when N/R, controller 3 needs to gather the status information of automobile, thus judges the opportunity needing unlatching and closedown.Concrete, controller 3 obtains the state of automobile by bus transceiver 2.And bus transceiver 2 comprises input end and mouth, wherein input end is connected with the CAN in automotive system, the speed of a motor vehicle is obtained from CAN, the car status information such as gear signal, and mouth comprises automobile gears signal output part G_OUT and vehicle speed signal mouth SP_OUT, be responsible for the automobile gears signal obtained from CAN and vehicle speed signal outwards to export respectively.
And controller 3 is programmable chip or circuit control module, it control output end comprising the automobile gears collection terminal G_IN be connected with automobile gears signal output part G_OUT, the vehicle speed signal collection terminal SP_IN be connected with vehicle speed signal mouth SP_OUT and connect laser transimitter 1, and control output end comprises the headlight control end F_CTRL connecting front the emission lamp 11 and back light control end B_CTRL being connected rear emission lamp 12.In addition, controller 3 is also provided with the master cock K1 that can control its own switch.In the process of automobile normal running, bus transceiver 2 is in the state of Real-time Obtaining automobile, and send vehicle condition signal to controller 3, the vehicle condition signal that controller 3 pairs of bus transceivers 2 are sent carries out implementing monitoring, when determining automobile gears and being in reverse, the rear emission lamp 12 that controller 3 controls automobile both sides laser transimitter 1 by back light control end B_CTRL is opened, and now chaufeur can judge automobile position by the laser projection on stronghold easily, thus avoiding obstacles.And when detecting that automobile gears is in forward gear, controller 3 judges speed of a motor vehicle state, when the speed of a motor vehicle is reduced to certain speed, excellent
choosingfor being less than 15Km/s, the headlight control end F_CTRL of controller 3 then controls to open front emission lamp 11.After use ancillary system, when chaufeur needs to close laser transimitter 1, close by master cock K1.Excellent
choosing, master cock K1 is Single switch button, presses and can open or close laser transimitter 1.
In the present embodiment, what controller 3 adopted is control module based on STM32 chip, and bus projector model is then TJA1044.
In preferred embodiment, by UART(Universal Asynchronous Receiver/Transmitter between controller 3 and bus transceiver 2, asynchronous receiving-transmitting transmitter) connect, signal acquisition efficiency can be improved.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
