METHOD FOR PROVIDING DRIVING DATA FOR AN ELECTRONIC LOGBOOK OF A MOTOR VEHICLE

Description

[0001] The invention relates to a method for providing driving data characterising a journey of a motor vehicle for an electronic logbook of the motor vehicle according to patent claim 1.

[0002] A logbook, for example, is required to record when a vehicle is used for private purposes and when it is used for business purposes. This logbook can then be presented as proof of use to a tax authority, for example. To avoid having to update the logbook manually, electronic logbooks are becoming increasingly popular.

[0003] One problem with the automated creation of logbooks is the recognition of the start and end times of a journey, for example when the vehicle is located in a dead zone where no connectivity can be provided for a positioning system that uses satellite data.

[0004] DE 10 2007 024 692 A1 describes a method for determining the distance traveled by a motor vehicle. Furthermore, US 2020 / 202 646 A1 describes the automatic creation of a logbook for commercial drivers based on vehicle data. Finally, US 2020 / 207 337 A1 describes a system for "automated valet parking."

[0005] The object of the present invention is to provide a method by which driving data of a motor vehicle can be provided or stored particularly advantageously for an electronic logbook.

[0006] This object is achieved according to the invention by the subject matter of the independent patent claim. Advantageous embodiments and further developments of the invention are specified in the dependent patent claims as well as in the description and the drawings.

[0007] The invention relates to a method for providing driving data characterizing a journey of a motor vehicle for an electronic logbook of the motor vehicle, wherein the driving data comprise a start time and / or an end time of the journey and position data which are recorded by a first position determination system and / or a second position determination system, and a detection of an automatic parking garage in an environment of the motor vehicle takes place, in which a change in the recording of the position data takes place from the first position determination system to the second position determination system and a parking process in the automatic parking garage is initiated or ended via a control signal and a start-stop signal is generated by the control signal and / or the change from the parking process to a drive mode or the drive mode to the parking process, in which start-stop signal the start time and / or the end time are stored.A parking garage control system sends an end-of-journey signal in the form of the aforementioned start-stop signal to a logbook backend when the motor vehicle is registered at a handover zone of the automatic parking garage. If the motor vehicle carries out the autonomous journey in the automatic parking garage, the parking garage control system sends a start-of-journey signal in the form of another start-stop signal. At the end of the journey, the parking garage control system sends a new start-stop signal, which now describes an end-of-journey signal.

[0008] The automatic parking garage is, in particular, a system known in English as Automated Valid Parking and thus an intelligent parking garage. At least one sensor system is present in the parking garage, allowing the vehicle to be parked or unparked to be picked up or handed over at a transfer area of ​​the automatic parking garage. Between the parking position and the transfer area, the vehicle operates in an autonomous mode, detecting, for example, or in particular, its position using the parking garage's sensor system. The automatic parking garage can be either an above-ground or underground parking garage, and thus an underground garage.

[0009] In other words, in the method according to the invention, data from intelligent parking garages that offer so-called Automated Valid Parking are used to recognize start-stop entries in a digital logbook and thus improve the corresponding position data or the start-stop entries.

[0010] The invention is based on the realization that measurement errors can occur when recording electronic logbooks, as the cited prior art shows. According to the prior art, however, these measurement errors are negligible, which can have inaccurate consequences, particularly with regard to taxes to be paid based on the logbook. For example, the automated creation of logbooks may not allow the start and end of a trip to be recognized in dead zones where there is no connectivity and no GPS signal. These dead zones can occur particularly in underground car parks, as mobile communications and GPS signals are often unavailable there, meaning the data cannot be sent to a logbook backend, for example.

[0011] This can have negative consequences for the user of the motor vehicle, as the journey may end too early and with an incorrect mileage. In the case of parking, the incorrect end of the journey typically occurs one to two minutes before the actual stop. In addition, or furthermore, the start-stop signal for the end of the journey cannot be received due to a lack of connectivity, meaning that a signal timeout must be waited for until the completed but incomplete journey is available to the user in the logbook. The problem when starting a journey is that the subsequent journey starts too late and, for example, a one to two minute delay also occurs. If the distance between the incorrect start and incorrect end is greater than one kilometer, the user has a gap that is particularly relevant for tax purposes, which must be processed manually.In addition to the inconsistent start and stop, this creates additional manual effort for the customer. This problem affects both logbooks where data is sent directly from the vehicle via a communication module, as well as logbooks that function or can be read via an OBD dongle and / or a smartphone solution, for example.

[0012] The method according to the invention has the advantage that no incorrect journey ends and / or starts are recorded and, moreover, a very accurate logbook can be kept.

[0013] In an advantageous embodiment of the invention, one of the positioning systems comprises a satellite navigation system, in particular GPS, GLONASS and / or Galileo and / or the other of the positioning systems comprises a sensor system of the automatic parking garage, such as LIDAR and / or ultrasound or the like.

[0014] In a further advantageous embodiment of the invention, the control signal is generated by parking the motor vehicle in a transfer zone of the automatic parking garage.

[0015] In a further advantageous embodiment of the invention, the start-stop signal comprises a handover time and / or a current mileage and / or a vehicle condition and / or a driver change.

[0016] Further advantages, features, and details of the invention will become apparent from the following description of a preferred embodiment and from the drawings. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the single figure, can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention.

[0017] It shows: Fig.Schematic side view of a motor vehicle and an automatic parking garage, which is designed to carry out a method for providing driving data.

[0018] The only figure shows a schematic view of a motor vehicle 10 and an automatic parking garage 12, wherein the two objects are intended to present a method for providing driving data characterizing a journey of the motor vehicle 10 for an electronic logbook of the motor vehicle 10.

[0019] In the method presented, the driving data comprise the start time and / or end time of the journey and position data which are recorded by a first position determination system 14 and / or a second position determination system 14, and a recognition of the automatic parking garage 12 in an environment of the motor vehicle 10 takes place, in which a change in the recording of the position data from the first position determination system 14 to the second position determination system 14 takes place and a parking process in the automatic parking garage 12 is initiated or ended via a control signal and a start-stop signal is generated by the control signal and / or the change from the parking process to a drive mode and / or the drive mode to the parking process, in which start-stop signal the start time and / or the end time are stored.

[0020] The automatic parking garage 12 is a parking garage with automated valid parking, in which sensors 16 of a sensor system 18 in the automatic parking garage 12 monitor the path of the motor vehicle 10, and the motor vehicle, in cooperation with a parking garage control system 20, drives autonomously from a drop-off area or transfer zone 22 to a parking space 24 in the automatic parking garage 12. As a result, the position and vehicle status in the automatic parking garage 12 are known even without GPS reception and / or the reception of another satellite system by the sensors 16 of the parking garage control system 20.

[0021] The vehicle state can describe whether the motor vehicle 10 is moving and whether this movement is autonomous or manual, and whether the motor vehicle 10 is stationary or parked. The automatic parking garage 12 is detected in the surroundings of the motor vehicle 10, for example, via a communication interface of the motor vehicle 10, in particular wirelessly via a radio signal that the automatic parking garage 12 transmits and which is generated, for example, upon the arrival of the motor vehicle 10 in the transfer zone 22 and received by the communication interface.

[0022] The parking garage control system 20 has, in particular, a permanent connection to the Internet and can thus establish a connection, for example, to a logbook backend in which the motor vehicle 10 or a control device 26 of the motor vehicle 10 can store the driving data recorded for creating the electronic logbook, which data include the end time, start time and position data.

[0023] For example, the method presented can be implemented as follows: The motor vehicle 10 drives into the transfer zone 22 in the automatic parking garage 12. There, the driver gets out and control of the motor vehicle 10 is transferred to the parking garage control system 20.

[0024] Since the motor vehicle 10 generally has no connection there and thus no reception of GPS data or another satellite system, the parking garage control system 20 sends an end-of-journey signal, for example in the form of the aforementioned start-stop signal, to the logbook backend when the motor vehicle 10 logs in at the handover zone 22. Logging in is initiated, for example, by the control signal from the user. For the start-stop signal, for example, an end-of-journey signal is generated, which contains the GPS coordinates of the drop-off area or the position coordinates of the drop-off area and the current mileage of the motor vehicle 10 with which the motor vehicle 10 was handed over to the parking garage control system 20. Furthermore, a vehicle status, i.e., the parking, is also recorded.

[0025] Thus, the correct end of the journey or the end time of the journey, which includes, for example, time, position and mileage, can be stored in the logbook and transmitted to the logbook backend, for example, by the parking garage control 20 and / or by a communication connection via the communication interface between the parking garage control 20 and the control device 26 of the motor vehicle.

[0026] If the motor vehicle 10 now performs the autonomous journey in the automatic parking garage 12, the parking garage control system 20 sends a journey start signal or another start-stop signal, for example, to the logbook backend or the control device 26. This journey start signal or start-stop signal can receive the position coordinates, in particular in the form of GPS coordinates of the drop-off area or transfer zone 22, as well as the current mileage that the motor vehicle 10 transmitted to the parking garage control system 20 during registration, as well as the vehicle status, which corresponds to a journey. The driver change is simultaneously recorded, so that the vehicle status corresponds in particular to an autonomous journey.

[0027] For the duration of the journey in the automatic parking garage 12 equipped with "Automated Valid Parking", the parking garage control system 20 transmits the travel signal with the current position in the automatic parking garage 12 and thus updates the position or the journey data for the electronic logbook.

[0028] At the end of the journey, the parking garage controller 20 sends a new start-stop signal, which now describes an end-of-journey signal. This end-of-journey signal can contain the GPS coordinates of the parking space or the position coordinates of the parking space, a current mileage that the motor vehicle 10 transmitted to the parking garage controller after the parking control station, and a vehicle status that is recorded as parking.

[0029] The pickup process by the user of the motor vehicle 10 is carried out in reverse.

[0030] Since the position determination in the automatic parking garage 12 is carried out by the sensors 16 of the parking garage control system 20, the motor vehicle 10 can, for example, also be advantageously tracked without GPS reception.

[0031] The following advantages arise from the use of the parking garage control 20: In an area without reception, the parking garage control 20 will convert the position in the parking garage into GPS coordinates, which can be provided to the electronic logbook or as extended, corrected driving data for the motor vehicle 10.

[0032] This allows the starting and / or ending positions, as well as the start and / or end times of a trip, to be determined with great precision. Furthermore, a driver change can be automatically documented. Furthermore, transmitting the mileage eliminates any tax-relevant gaps. List of reference symbols
