The visual field in.
The content of the invention
As background, a kind of side for being used to represent road signs information is introduced according to independent claims using the present invention
Method, a kind of equipment using this method is introduced in addition and finally introduces a kind of corresponding computer program product.Favourable structure
Type is drawn from corresponding dependent claims and following description.
System information directly faded in the visual field of vehicle driver is referred to as head-up display（Head-up
Display）.Unlike this, the feelings for the combination instrument that driver must be in the case of head down display or in vehicle
Its sight is reduced under condition, to see the important display of such as speed or direction instruction.Although the number in the case of head-up display
According to being projected directly on windshield, but impression as occurring for driver, i.e. image hang more than hood
Float over that about two and half is remote away from it.This advantageously, driver again need not remove sight from traffic events.
Information can also directly be faded in into true picture by head-up display.The display is referred to as in general term
Contact simulation or augmented reality head-up display.Can be, for example, that driver provides navigation hint by means of the technology, its mode
It is that the navigation hint is by the street before driver up to horizon labeled as colour.It can also show as arrow
Navigation hint of the head on runway.Driving trace or by ACC system --- adjusted namely for adaptability speed
The system of section --- the traveling detected is in the visual field that vehicle above can also directly be faded in driver.Image is big
About 10m is adjusted to horizontal anopsia（akkommodationsfrei）Distance in, being regarded in the virtual of head-up display
Yezhong is generated.
Contact simulation head-up display can be used for being driver by the warning for being related to the road section to be travelled
Prompting is projected directly into the visual field of the driver.With alert accordingly, can be driver by for being related to what is travelled
The regulation of road section or the prompting of ban are projected directly into the visual field of the driver.The projection can so enter herein
OK, i.e., the prompting to position is embedded in the true surrounding environment of vehicle, and this makes driver receive and understand that the prompting becomes
Easily.For example, the prompting can be projected directly on the surface for the visible section of driver of runway.Such as it can incite somebody to action
Prompting projection to since it the prompting there is the position of validity.If cause the position close to the position to the such degree of vehicle
Put in the virtual visual field in head-up display, then the prompting can be projected and give the position in which contact simulation by head-up display.
As viewed from the perspective of driver, the prompting is revealed as being physically located in the true surrounding environment of the opening position it.
If vehicle continues in the case of the distance in view of reduction by head-up display to be continued close to the position, the prompting
Project to contact simulation and give the position.Therefore driver has its sensation close to the prompting, as being for example applied to driving
In the case of true prompting on road surface like that.Contact simulation prompting can project to driver's seat with non-contact simulation
In status information area be used together.The prompting of contact simulation ground projection and the status information area of non-contact simulation ground projection can
To be so projected in the visual field of driver so that the prompting of contact simulation ground projection is in vehicle close to contact simulation prompting
It is transferred in status information area and is taken over finally by status information area and there as viewed from the perspective of driver during position
As long as there is validity just to keep existing as non-contact simulation prompting for the prompting.Even if when vehicle driver is for example due at a high speed
Degree receives contact simulation prompting without the time, so by the way that contact simulation prompting is transferred into non-contact emulation mode information
Notice the driver in area in the display in status information area to be changed.Because the prompting is then enduringly shown
For the part in status information area, driver has sufficient time to receive the information content of the prompting.
For representing that the method for road signs information has following steps for vehicle driver：
It is determined that the position of the travel route along vehicle, wherein being assigned with the effective district of road signs information to the position
The beginning in domain；With
Produce and show that signal is used to simulate virtual representation as the contact relevant with the position（Darstellung）Display
Road signs information.
Vehicle can be motor vehicle, such as car or truck.Vehicle can have such as head-up display form
Projection arrangement.The projection arrangement can be structured as that contact simulative display and non-contact simulative display are projected to vehicle and driven
In the visible range for the person of sailing.Show that signal can be electric signal.It is to cause that display signal, which goes for projection arrangement manipulation,
Projection arrangement is projected to road signs information as contact simulation virtual representation in the visual field of driver.Road signs information can
With the information including danger signal or the information of regulations mark, danger signal prompting is dangerous and the regulations sign prompting is advised
Fixed or ban.Thus road signs information can be with corresponding traffic sign or with the table shape word of similar traffic sign
Form is shown.The road signs information can for example prompt speed to limit and in the form of limit signs by table
Show.Travel route can be the circuit through planning of the road section before vehicle.Data on travel route can be with
Exported by the navigation system of vehicle.The beginning of the effective coverage of road signs information can be determined based on the data stored.
Data on effective coverage can be stored in the storage device for example in the form of the numerical map in vehicle or via connecing
Mouth calls from the storage device of outside vehicle.Position may indicate that in the region of the beginning for being disposed in effective coverage truly
Point.The position can for example be directly arranged at effective coverage beginning, from before the beginning of effective coverage nearby or from
After the beginning of effective coverage nearby.The position may indicate that will be by the place on the runway of vehicle traveling.The position
It may also indicate that the place being arranged in beside the runway to be travelled.
Different display signals can be produced for the different spacing between vehicle and position in the step of producing.Thus
Road signs information can be shown as to the contact simulation virtual representation relevant with the position with different stretching, extensions.If car
Spacing between the position changes, then new display signal can be produced, to ensure as viewed from the perspective of driver
Continue to show road signs information in the opening position.Different display signals can produce in succession in time.When first
When have passed through predetermined time period after display signal or walk to be over predetermined distance, such as new display letter can be produced
Number.In addition to stretching, extension, the shape of road signs information and expression can be identical in different display signals.Because different are stretched
Exhibition, road signs information show in different sizes when away from the position difference spacing as viewed from the perspective of driver.
Such as different display signals can be produced so that the spacing between vehicle and the position becomes smaller, with
The difference of the relevant contact simulation virtual representation in the position, which is extended in the first spacing range, just becomes bigger, and in vehicle
Spacing between the position becomes smaller, just becomes smaller in the second spacing range, wherein the second spacing range is wrapped
What is included is smaller than the spacing included by the first spacing range.If vehicle close to the position, road signs information with it is true
Real representation accordingly at first appears to become much larger.But since a determining deviation, the spacing of pitch mark first and second
Boundary between scope, the road signs information are expressed less and less.Thus road signs information can be transferred to shape

Analog representation is abreast carried out with the contact analog representation of new road signs information.In this way can be in status information area
First, currently valid road signs information, such as currently valid rate limitation are inside remained displayed in, and by new traffic mark
Will information, for example effective rate limitation is shown as contacting analog representation soon.
When the expression for being produced as display signal to cause status information area in the step of generation implemented shows signal
When contact simulation virtual representation with road signs information is least partially overlapped, such as it can implement to generate other display signal
The step of.It is this when the contact analog representation of road signs information is transferred to as viewed from the perspective of driver in status information area
Kind situation.Once once in the presence of partly overlap, exist it is completely overlapped or once contact analog representation reached and be directed to traffic mark
The non-contact analog representation of will information, the conversion contacted between analog representation or non-contact analog representation can be carried out.
Smooth transition can be realized between contact analog representation and non-contact analog representation in this way.Phase can be produced herein
After display signal so that the expression of distortion in perspective of road signs information always continues to zoom out, so as to realize from
Contact smooth transition of the analog representation to non-contact analog representation.In non-contact analog representation, road signs information can be
Only slight distortion it is expressed without distortion or in perspective in perspective.
