Description

[0001] The present invention relates to a method for detecting a circular route. State of the art

[0002] In geoinformatics, information systems for the acquisition, processing, organization, analysis, or presentation of spatial data are commonly referred to as geographic information systems (GIS), geographic information systems, or spatial information systems (RIS). A well-known method of data acquisition is field data collection using global navigation satellite systems (GNSS).

[0003] DE 10 2009 020 997 A1 discloses the subject matter of the preamble of claim 1.

[0004] From US 2010 / 0106356 A1, a device is known with means for driving along the lateral track boundaries of a circular track with a motor vehicle and means for recognizing the track layout of this circular track based on the track boundaries.

[0005] German patent application DE 10 2014 204 892 A1 discloses a vehicle mapping system. The mapping system comprises an electronic storage device located in the vehicle, a GPS receiver, and an electronic controller. The electronic controller is configured to receive GPS data from the GPS receiver indicating the vehicle's current location. The electronic controller is also configured to store the GPS data on the electronic storage device when the vehicle's location is outside a defined area. This occurs, in particular, when the vehicle deviates from its current course by a certain distance, which is detected when the vehicle's location exceeds a predefined or programmable "parallel threshold." Disclosure of the invention

[0006] The invention provides a method for recording a circular route.

[0007] One advantage of this solution lies in the possibility of essentially "reading" any circular route into a vehicle. The route is recognized much more accurately compared to conventional mapping systems, as the track boundaries on both sides of the circuit are driven.

[0008] The vehicle, following the identified track layout, preferably drives the circuit autonomously several times, thereby determining an ideal line or even the track's condition. This enables the vehicle to autonomously and quickly lap the circuit in a manner typical of sports cars.

[0009] Once the ideal racing line has been determined, the vehicle is put into a training mode in which it provides feedback along the track on the ideal line, braking points, turn-in and apex points, and / or information on optimal line of sight. The driver thus has their own personal driving instructor, embodied by the vehicle itself, always by their side on the track.

[0010] The driver may ultimately be given the option of switching the amount of information or support on or off as desired, in order to approach both the limits of their own driving ability and the performance limits of the vehicle in a controlled, safe and step-by-step manner. Brief description of the drawings

[0011] An embodiment of the invention is described in Fig. 1 is shown and is described in more detail below. Fig. Figure 1 shows the activity diagram of a method according to the invention. Fig. Figure 2 shows a simplified view of a device. Embodiments of the invention

[0012] Fig. Figure 1 illustrates the basic steps of a procedure (10) for capturing a Fig. 2 schematically represented circular track (33) according to an embodiment of the invention. The starting point of the present exemplary consideration is the following scenario: an arbitrary handling course far from any civilization. No track data exists.

[0013] The driver is driving from the observer's perspective. Fig.1. The motor vehicle first traces the left, then the right track boundary of the circuit (33) (Action 11). Based on the track boundaries, the motor vehicle recognizes (Action 12) the track layout of the circuit (33) and displays the message "Track layout recognized" to the driver on an information display (34).

[0014] On the vehicle's information display (34), the driver is prompted to confirm (13) with the message "Confirm with OK to determine ideal racing line". Once this confirmation is given, the vehicle automatically drives (action 14) the circuit (33) several times, thus determining its ideal racing line and track conditions. The vehicle acknowledges this action (14) with the following message: "Ideal racing line and track conditions determined, enjoy!"

[0015] It should be noted that previously known race tracks, including the ideal line, braking and turn-in points, may be stored on a storage medium accessible to the motor vehicle without leaving the scope of the invention.

[0016] The vehicle is now put into a training mode (Action 15) in which it provides the driver with information (16, 17, 18, 19, 20, 21) along the circuit (33) regarding the ideal racing line, either detected or retrieved from the storage medium. This could include, for example, the direct display of the ideal racing line (Action 16), recommended braking points (Action 17), or optimal line of sight (Action 18) along the circuit (33), such as by projection (31) onto the vehicle's windshield (32). Furthermore, targeted steering inputs (Action 19), braking inputs (Action 20), or other pedal inputs (Action 21) could be provided. Additionally, target-actual comparisons of all the aforementioned parameters are conceivable to achieve the greatest possible learning effect.
