A kind of assisting navigation device
Technical field
The utility model relates to a kind of traffic navigation technical field, especially a kind of assisting navigation device.
Background technique
Existing traffic navigation system is usually to utilize dedicated navigator or Mobile Telephone Gps software according to the starting point of setting
And destination, cook up a driving route.
Existing navigation system is generally combined by picture navigation and Voice Navigation and completes navigation operation.Wherein, it draws
Face navigation is to show that running informations, the Voice Navigation such as map and the steering of car present position crossing then mention in operating terminal
Forward direction driver provides the running informations such as crossing steering.
However, needing to show when encountering the complex road conditions such as the more or rotary island of crossing fork in existing navigation system
Information content it is too big, and general operation terminal screen is smaller, can make screen content is very complicated in disorder to be not easy it is clear that when driving a vehicle such as
The small screen that fruit stares at always side, which is seen, easily causes accident.In addition, encounter ambient sound it is very loud when do not hear in casting
Hold, or encounter crossing diverge the complex road conditions such as more or rotary island when need the information content that prompts too big, broadcast of long duration
It is easy to miss crossing, is easy malfunction when broadcasting in advance again.
Furthermore existing navigation system is when straight trip slightly has the deviation of directivity, such as left front, can report into " turning left ";Or
Person can report right front to being not easy to distinguish when a plurality of road occur, such as occurring two or more roads on the right;To send out
Raw errored message, so that the driver that driver, especially sense of direction be not strong, in complex situations because correct navigation can not be differentiated
Information and cause it is a series of mistake drive.
It would therefore be desirable to a kind of auxiliary device, simply to transmit navigation information to driver.
Utility model content
One of the utility model is designed to provide a kind of assisting navigation device, can simply pass to driver
Navigation information is passed, in the case where not needing driver and giving extra care power, and correctly navigation clear to driver's transmitting
Information.
To solve the above problems, the utility model provides a kind of assisting navigation device, it is connect with a navigation system.It is described auxiliary
Helping navigation device includes: a protecting cover for steering wheel, and the protecting cover for steering wheel is used to be sheathed on the steering wheel of vehicle;One shines

Fig. 2 is the operating status schematic diagram of the assisting navigation device of an embodiment of the present invention.
Specific embodiment
The preferred embodiment of the utility model is introduced below with reference to Figure of description, it was demonstrated that the utility model can be implemented,
The embodiment can keep its technology contents more clear and just to those of skill in the art's complete description the utility model
In understanding.The utility model can be emerged from by many various forms of embodiments, the protection scope of the utility model
It is not limited only to the embodiment mentioned in text.
A kind of assisting navigation device 100 is provided in the present embodiment.
The assisting navigation device 100 includes: a protecting cover for steering wheel 110, a luminescence component 120 and a controller 130.
In the present embodiment, the luminescence component 120 is a commercially available light bar, has a plurality of illuminating parts 121, such as but not
It is limited to small lamp bulb or light emitting diode.
As shown in the figure, the small lamp bulb 121 of the luminescence component 120 is along the outer of the protecting cover for steering wheel 110
Even circumferential is alternatively arranged.Display error can be extrapolated by following formula: it sets the light bar average mark and is furnished with N number of small lamp bulb 121,
Then the included angle A between two small lamp bulbs 121 of arbitrary neighborhood is 360/N, and maximum display error is A/2.It is 12 to be with typical N
, the angle between adjacent two small lamp bulb 121 is 30 degree, and maximum angles of display error is then 30/2=15 degree.It is thus clear that small
121 quantity N of lamp bead is bigger, and maximum display error is smaller.
As shown in the figure, the controller 130 is connect by a data line with the luminescence component 120.Also, the control
Device 130 processed receives a navigation instruction from a navigation system 200, and then is sent by the data line to the luminescence component 120
Luminous signal.
As an example, the controller 130 is connect with the navigation system 200 by a USB data line, by described
USB data line carries out data transmission.Certainly, the controller 130 can carry out CAN communication with the navigation system 200, will
Navigation instruction is transmitted to the controller 130.
In the process of running, the navigation signal synchronous driving of the navigation system 200 is to the controller 130, then by
Whether the illuminating part 121 that the controller 130 controls the luminescence component 120 shines.It is positive for example, defining 12 directions of clock face
Front, 6 directions are dead astern, 3 directions are front-right, 9 directions are front-left.When vehicle normally moves forward, 12 points
The illuminating part 121 in direction shines.Alternatively, in order to save energy, definition maintains the illuminating part 121 in front 12 directions when driving
It does not work.When needing nature to turn to without fork crossing, the illuminating part 121 for controlling respective direction shines.For example, it is desired to when turning right, 3
Point direction illuminating part 121 shines;When needing to turn around, 6 direction illuminating parts 121 shine.When encountering multiple crossings or rotary island etc.
When complex road condition, all directions crossing corresponds to that lamp is all bright, and the illuminating part flashing for the corresponding direction that navigates prompts correct direction, such as Fig. 2
Shown in, the right in current driving direction has 2 optional driving directions, and there is 1 optional driving direction on the left side, and also turning around can
Driving direction is selected, thus, the illuminating part 121 in 1 point, 2 points, 6 points and 9 direction shines, the illuminating part 121 for the corresponding direction that navigates
(illuminating part 121 in 1 direction in Fig. 2) flashing, to prompt correct direction.
It will be appreciated by those skilled in the art that, the assisting navigation device 100 can pass through a power supply line and a power supply
Connection, for providing power supply to the controller.The power supply can be Vehicular power supply system, be also possible to battery etc.
External power supply.That is, the controller 130 can connect interior power supply interface by a such as power supply line, to obtain electricity
Energy.Alternatively, an external power supply can also be arranged on the controller 130 in the assisting navigation device 100, pass through a battery
Obtain electric energy.
In the assisting navigation device of the utility model, by being sheathed on steering wheel by protecting cover for steering wheel,
Realization provides a visual cues on the steering wheel.Therefore, the assisting navigation device of the utility model can be in driving procedure
In, the prompt of navigation information is provided within the scope of driver's normal vision, sight and attention without dispersing driver.
In addition, the assisting navigation device of the utility model does not have acoustic information, because without being influenced by ambient noise.
The assisting navigation device of the utility model has many advantages, such as that display is quick, comprehensive, accurate, compatibility is high, can
To be used together with existing navigation system, so that providing other than Voice Navigation, picture navigation for driver includes angle
