Definitions
- the present invention relates to transferring positions between different map data.
- the invention relates to the transfer between systems on board a motor vehicle that use different map data.
- a motor vehicle comprises a first and a second system, each of which processes location-related information.
- the first system can, for example, comprise a driver assistance system that can support or control a driving function of the motor vehicle
- the second system can comprise a navigation system that is set up to plan a route between a current position and a predetermined target position.
- the first system is based on first map data and the second on second map data.
- the first system can determine and provide a planned position of the motor vehicle with reference to the first map data.
- the first and second map data can differ significantly from each other and/or from reality.
- the first position, which is adopted unchanged, can therefore, for example, lie outside a road or even on a different road when referring to the second map data.
- a position can also be based on absolute geographic coordinates.
- available map data that also use absolute geographic coordinates usually have an error in the range of up to approximately 0.01 mm.
- An object underlying the present invention is to provide an improved technique for relating a position related to first map data to second map data. The invention solves this problem by means of the subject matter of the independent claims. Subclaims give preferred embodiments.
- a method for referencing a route of a vehicle related to first map data to second map data comprises steps of determining first positions on the route with respect to the first map data; assigning a lane that the vehicle travels in at the first positions; providing the first positions with the respectively assigned lanes; determining second positions with respect to the first positions and the respectively assigned lanes.
- the positions of the route can easily be related to or referenced to the second map data.
- the process can be carried out with any first and second map data.
- the map data can, for example, use different map systems, different geoids or different surveying systems.
- a lane-accurate transfer of the positions from the first to the second map data can be achieved.
- the first position can be transferred to the second position in such a way that the lane traveled is correctly reproduced.
- Such a transfer is also referred to herein as lane-accurate.
- a lane is always related to a road that encompasses the lane. It can usually be assumed that the vehicle should always be on a road.
- the lane can be displayed with reference to the road, for example by counting the lanes of the road from right to left or from left to right. For example, a lane that points to a road according to the first map data can be easily converted into a lane related to a road according to the second map data.
- the route comprises a reference position for which a first position with respect to the first map data and a second position with respect to the second map data are known.
- An absolute deviation of the reference position according to the first map data from the reference position according to the second map data can be determined in this way. This deviation can be applied to positions within a predetermined area around the reference position. In this way, the vehicle's planned route can be transferred easily and quickly from the first to the second map data.
- the reference position can in particular comprise a current position of the vehicle.
- the position can be determined using one or more positioning systems on board the vehicle. Measurements from the positioning systems can be used to determine the current position of the vehicle with reference to the different map data.
- the route is preferably a planned route that extends forward in the direction of travel from the current position of the vehicle.
- the first positions are comprised of a polyline.
- the polyline may represent a sequence of positions that are linked together. This allows a position to be specified relative to a previous or subsequent position. Data to be transmitted may be reduced and processing of the positions may be simplified.
- a sequence of predetermined first positions includes a change of the lane traveled. Using the method presented here, such a driving maneuver can easily be transferred from the first to the second map data.
- a lane change maneuver may include an indication that Starting from a current position of the vehicle as a reference position, a change from the second to the third lane of the road is to take place from the right in approximately 50 meters along the road.
- the first position can be assigned a reference to an undefined lane.
- An undefined lane can apply, for example, in the area of an intersection or during a turning maneuver.
- the shape of a curve that is described by first positions in this area can be adjusted accordingly between second positions before and after the area. In this way, the route can also represent a realistic course with regard to the second map data.
- a lateral position of the second position can be determined with respect to a boundary of the road being traveled. For example, if the vehicle is to travel in the second lane from the right with respect to the first map data and the road has four lanes according to the first map data, the lateral position of the vehicle with respect to the second map data can be determined by dividing the road into four equally wide sections according to the second map data, which can be viewed as lanes.
- the lane being driven on can be defined as an area whose lateral distance from the right edge of the road is between one and two widths according to the second map data. In this way, the vehicle can be positioned on different "virtual" lanes with respect to the second map data. It is irrelevant whether lanes are marked on the road or not.
- the first map data have a higher level of detail and/or a higher level of accuracy than the second map data.
- the first map data can be included in a driver assistance system and/or the second map data can be included in a navigation system.
- the driver assistance system can determine a lane traveled by the vehicle with high reliability. By means of the method described This reliability or accuracy can be used as a basis for information regarding the second map data.
- a device for referencing a route of a vehicle based on first map data to second map data comprises a first map memory for the first map data; a second map memory for the second map data; and a processing device.
- the processing device is designed to determine first positions on the route with respect to the first map data; to assign a lane that the vehicle travels on at the first positions; to provide the first positions with the respectively assigned lanes; and to determine second positions with respect to the first positions and the respectively assigned lanes.
- the processing device can be set up to partially or completely carry out a method described herein.
- the processing device can be implemented electronically and can comprise, for example, a programmable microcomputer or microcontroller.
- the method can be in the form of a computer program product with program code means.
- the computer program product can also be stored on a computer-readable data carrier. Additional features or advantages of the method can be transferred to the device, or vice versa.
- a vehicle comprises a device described herein.
- the vehicle preferably comprises a motor vehicle, in particular a motorcycle, a passenger car, a truck or a bus.
- Figure 1 shows a device on board a vehicle
- Figure 2 is a flow chart of a method; and Figure 3 illustrates an exemplary route of a vehicle.
- Figure 1 shows a device 100 on board a vehicle 105.
- the vehicle 105 is shown as a passenger car by way of example; in other embodiments, another type of vehicle can also be included.
- the device 100 comprises a processing device 110, a first map memory 115 and a second map memory 120.
- the map memories 115, 120 are each set up to store map data.
- First map data 125 is stored in the first map memory 115 and second map data 130 is stored in the second map memory 120.
- the first map data 125 is high-precision (HD: High Definition) and can be used by a first system 135, which can include, for example, a driver assistance function, an automatic or autonomous control of the vehicle 105.
- the second map data 130 is, for example, of single precision (SD: Single Definition) and can be used by a second system 140, which, for example, includes a navigation system.
- the map data 125 and 130 serve different purposes and can accordingly be optimized with respect to different criteria.
- the first map data 125 can be optimized primarily with respect to lanes that are included in a drivable road or a classification of roads, for example into local roads, country roads and motorways.
- the second map data 130 can be optimized with respect to timeliness, traffic regulations or traffic flow information. In this way, a driving maneuver of the vehicle 105 can be specified in an improved manner with respect to the first map data 125, while the determination of an advantageous route can possibly be carried out more easily with respect to the second map data 130.
- a positioning device 145 can be provided to determine a geographical position of the vehicle 105.
- the positioning device 145 shown is designed as a receiver of a satellite-based global navigation system (GNSS) such as GPS, Glonass or Galileo.
- GNSS satellite-based global navigation system
- An exemplary further possibility for determining the position of the vehicle 105 is given in the illustration in Figure 1 by a camera 150, which is set up to scan a landmark in an environment of the vehicle 105.
- a geographical position of the landmark can be determined on the basis of first or second map data 125, 130.
- the position of the vehicle 105 can be determined with respect to several landmarks.
- the route To transmit a route between the first and second systems 135, 140, it is proposed to convert the route into a sequence of positions that are related to the first map data 125.
- the positions can then be enriched with information that more precisely determines a lateral and/or longitudinal position with respect to the first map data 125 and that can be transferred to the second map data 130.
- a longitudinal position indication may comprise a distance from a predetermined position along a traveled roadway.
- a transverse position may relate to a numerically specified lane of the roadway.
- the additional information can then be evaluated on the basis of the transmitted positions with respect to the second map data 130.
- Figure 2 shows a flow chart of a method 200 for referencing a route related to first map data 125 to second map data 130.
- the method 200 can be carried out in particular by means of the device 100 on board the vehicle 105.
- a geographical position of the vehicle 105 can be determined. This position is also called ego position and is related to a predetermined point in time.
- a planned route of the vehicle 105 can be determined.
- the route can be defined, for example, by the first system 135 and can carry out a predetermined driving maneuver of the vehicle 105 in detail, for example a turning maneuver.
- the route usually extends over a predetermined distance, the length of which can be limited, for example to approximately 1 km, approximately 500 m, approximately 200 m or approximately 100 m.
- first positions can be determined which are related to the first map data 125 and represent the route.
- the number of first positions is not limited, but there should be at least as many first Positions must be determined so that a maneuver performed along the route can be represented clearly and completely.
- a polyline may be formed which connects the first positions in their order on the route.
- the polyline may comprise a sequence of first positions.
- a lane traveled or to be traveled by the vehicle 105 can be determined for each first position on the polyline.
- Information about lanes that are included in a traveled road can be determined from the first map data 125.
- the lateral position of the vehicle 105 on the road can be expressed as an integer that represents the lane currently being traveled.
- first positions can each be enriched with distances from other first positions.
- a reference position is determined to which the positions of the route in the longitudinal direction of the road relate.
- the first positions, each enriched with additional information, can be provided to the second system 140 in a step 225 in absolute form or in the form of a sequence, for example as a polyline.
- the first positions of the route can be related to the second map data 130.
- the information with which the first positions were enriched can be evaluated and related to the second map data 130.
- a lateral position of the vehicle 105 can also be determined here with respect to a number of known lanes of a traveled road.
- a longitudinal position along the road can be determined with respect to a predetermined reference position.
- the ego position recorded in step 205 with respect to the second map data 130 can serve as the reference position.
- Figure 3 shows an example route 300 that the vehicle 105 is to travel.
- the route 300 describes a turning maneuver at an intersection 305.
- a first road 310 extends and a second road 315 extends in the horizontal direction.
- the first road 310 has three lanes 320 per direction of travel, while the second road 315, for example, only comprises two lanes 320 per direction of travel.
- the vehicle 105 is located at the bottom edge of the illustration in Figure 3 with the direction of travel upwards on a middle lane 320 of the first road 310.
- an exemplary scale 325 is drawn to the right of the first road 310, which indicates units of 50 m along the first road 310.
- the route 300 comprises a number of first positions 330, which are shown by way of example by circles in Figure 3.
- a current position of the vehicle 105 in the illustration in Figure 3 can be determined as a reference position 335.
- the reference position 335 can be determined both with respect to the first map data 125 and with respect to the second map data 130.
- Route 300 requires that vehicle 105, after traveling approximately 50 m in the middle lane 320 of the first road 310, changes to the lane to the left and continues straight ahead until the stop line. As far as traffic permits, vehicle 105 should then turn left in an arc and continue in the right lane of the second road 315.
- the first positions 330 can each be enriched with longitudinal and/or transverse information. In the intersection area where the roads 310, 315 intersect, no lanes 320 are defined. Here, the first positions 330 can be enriched with the information that a definition of lanes 320 is not possible or is not provided for in the first map data 125.
- the enriched first positions 330 of the route 300 can be transmitted to the second system 140 and dereferenced there with respect to the second map data 130. Starting from the reference position 335, both longitudinal and transverse additional information can be evaluated. This means that the route 300 can also be expressed with respect to the second map data 130. The specific route 300 can then be output on board the vehicle 105 on a map display, for example.
