Description

[0001] The invention relates to a method for providing a ride-sharing opportunity for a user in the event of vehicle damage, as well as an associated system comprising at least one stationary communication device and a central server device.

[0002] When driving a vehicle, it may happen that the vehicle is damaged, for example, as a result of an accident or vehicle breakdown. Both an accident and a vehicle breakdown are unexpected events and can present the user of the damaged vehicle with the challenge of finding an alternative way to reach their desired destination in a timely manner. In particular, a towing service or assistance from a vehicle insurance company may arrive too late to reach the desired destination in time.

[0003] US 2021 / 0133906 A1 relates to a system and method for obtaining roadside assistance. Vehicle sensors detect that the vehicle is in an inoperable condition. The vehicle then communicates with a roadside assistance provider to request roadside assistance. The vehicle also automatically communicates with a ride-sharing service provider to request a shared vehicle.

[0004] However, it may happen that the vehicle has sustained significant damage, meaning it can no longer request a ride-sharing service because the relevant systems have failed. The current method would then be unfeasible, leaving the user once again faced with the problem described above.

[0005] The invention is based on the object of providing a method for providing a ride for a user in the event of vehicle damage, which is improved and, in particular, vehicle-independent.

[0006] The problem is solved by the subject matter of the independent patent claims. Advantageous developments of the invention are described by the dependent patent claims, the following description, and the figures.

[0007] A first aspect of the invention provides a method for providing a ride to a user in the event of vehicle damage. The method comprises, in particular, the following steps: - Providing a stationary communication device in a road environment; - transmitting a request for a ride from the communication device to a central server device, depending on an input from the user into the communication device; - Forwarding the request from the central server device to a selection of motor vehicles; - Transmitting an acceptance for the ride from at least one motor vehicle of the selection of motor vehicles by means of the central server device to the stationary communication device, depending on an input from a driver of the motor vehicle.

[0008] The method can be used to improve the provision of a ride for the user in the event of vehicle damage, particularly regardless of the type of vehicle damaged. This can be particularly advantageous if the vehicle is so damaged that it cannot offer any assistance in providing a ride. The method can help users who can no longer use the damaged vehicle to be provided with a ride quickly and easily, enabling them to reach their destination on time or at least as early as possible. By providing a ride, it can also be ensured that a driver, for example from a taxi company, does not have to be specially commissioned to pick up the user.Instead, other road users who are already traveling by motor vehicle can pick up the user in their vehicle. This can involve only a small detour. In particular, the reduced use of motor vehicles can conserve resources and the environment.

[0009] In contrast to a traditional ride-sharing exchange, the ride-sharing service of the inventive method can be provided extremely spontaneously. Long waiting times can thus be advantageously avoided. With the ride-sharing exchange, rides are planned weeks, days, or at least several hours in advance, whereas ride-sharing services can be provided unplanned using the inventive method.

[0010] Another advantage may be that the user doesn't need a smartphone or similar device to arrange a ride. This can be particularly beneficial for users whose smartphones have also been damaged or who don't own one.

[0011] Preferably, a plurality of stationary communication devices can be provided, in particular evenly distributed at a definable distance across a road network. In particular, the stationary communication devices can be provided on highways, federal highways, country roads, or the like, for example, at a distance of a few hundred meters, in particular within line of sight.

[0012] Stationary can be understood in particular to mean that the communication device is immobile or mobile, i.e., preferably firmly anchored in one location. The surroundings of the road can refer in particular to the roadside, a hard shoulder, breakdown bays, or the like, as well as, in particular, rest areas, parking lots, and stopping points located directly on the road. The surroundings can also be referred to as the immediate area.

[0013] The electronic communication device can in particular have transmitting and receiving devices, as well as interfaces for communication with the user (Human Machine Interface, HMI), for example a touch display or an acoustic receiving device.

[0014] In one step, it may be provided that the user, whose vehicle has sustained damage or broken down on or in the vicinity of the road, goes to the communication device due to the vehicle damage and enters an input into the communication device. The input can be made, for example, via speech into the acoustic receiver or via haptic input into a keyboard or touch display. For example, a predefined digital form can be filled out. It may also be provided that an automated voice specifically prompts the user to make certain voice inputs and, if necessary, to confirm them.

[0015] The input can additionally and optionally be used to alert traffic safety services, towing services, insurance services or emergency services.

[0016] Preferably, the user's input can be used to request a ride. For this purpose, the user can enter various information required for a ride. The input can be confirmed, for example, using a confirmation field or a send field.

[0017] The request relates in particular to the fact that the user would like to be given a ride by a driver of a motor vehicle in order to travel together.

[0018] As a result of the input, it is particularly provided that the request is automatically transmitted from the communication device to a central server device immediately in time. In other words, the communication device sends the request, and the server device receives the request. The communication device and the server device can be connected to each other, in particular, by wired or wireless signaling, for example via a landline, internet, fiber optic, mobile network, or satellite connection.

[0019] A data transmission protocol, such as TCP / IP, may be used to transmit the request. The request is transmitted in the form of data, possibly encrypted, using signal technology.

[0020] The electronic server device can also be provided in a decentralized manner. The server device can be an electronic device with a computer program that provides functionalities, utilities, data, or other resources so that other devices or programs ("clients") can access them, usually via a network. This architecture is referred to as the client-server model, where the communication device can correspond to the client.

[0021] The server device can be configured to automatically process, convert, convert, store, and / or similarly process the request or the request data. Speech data can, in particular, be convertible by speech recognition software of the server device.

[0022] The request received by the server device, in particular the processed request data, can then be automatically sent to the selection of motor vehicles, and in particular, received, read, and processed by the selection of motor vehicles. The motor vehicles in this selection have, in particular, corresponding electronic modules to receive the request data. The motor vehicles can have corresponding electronic receiving, processing, and computing units for this purpose. A respective motor vehicle, or a respective module of the motor vehicle, can also correspond to a client of the client-server model.

[0023] The motor vehicles in the selection can, in particular, meet a predefined selection criterion, so that these motor vehicles are selected according to the predefined selection criterion. The selection can, for example, comprise only one motor vehicle, less preferably no motor vehicle, and preferably a plurality of motor vehicles, for example, on the order of 10, 100, or 1,000.

[0024] The request can be sent immediately, for example, via a signal-based communication connection directly from the server device to the selection of motor vehicles, but preferably indirectly. The transmission is particularly wireless, for example, via mobile radio or the like. The transmission can also be made indirectly via another electronic device, which is, for example, directly and wirelessly connected to the motor vehicle. It is also conceivable that the request could be transmitted to the selection via radio, whereby the selection of motor vehicles can depend on the range of the radio.

[0025] In one step, the request can be automatically issued to the respective driver of the selected vehicle, for example, via voice, display, or HMI. Based on this request, the driver can decide whether to accept the request. The driver of the vehicle can also correspond to the front passenger or a passenger.

[0026] It can also be provided that the driver corresponds to a (fully) autonomous, electronic vehicle guidance system that drives the motor vehicle with or without a human occupant. In this case, the request is transmitted via signal to an electronic decision unit of the vehicle guidance system, which makes the decision to allow the vehicle to be taken along based on the request. The decision can, for example, be based on parameters that can be specified by a human driver.

[0027] If the driver decides that the request for a ride should be accepted, a corresponding input can be made, for example acoustically, haptically or through signals.

[0028] As a result, it is particularly provided that the driver's acceptance of the ride-sharing opportunity is transmitted from the motor vehicle to the stationary communication device by means of the central server device, preferably via a signaling communication connection as already described.

[0029] It can be provided that the acceptance can be output to the user by the stationary communication device. Furthermore, it can be provided that the user can confirm the acceptance, with the confirmation being sent to the motor vehicle. It can also be provided that the user can reject the acceptance, with the rejection being sent to the motor vehicle. This can be provided in particular if multiple acceptances from several motor vehicles in the selection of motor vehicles are transmitted to the communication device.

[0030] Depending on the assumption or a confirmed assumption, it may be provided that the driver is automatically provided with a route to the communication device via a navigation device, and optionally to a user's destination. An autonomous vehicle guidance system can, in particular, automatically take the route to the communication device.

[0031] In a further step, the vehicle may be driven to the stationary communication device or to an alternative, agreed-upon pickup location. Furthermore, the user can board the vehicle and be transported according to an agreed-upon arrangement.

[0032] The invention also includes embodiments which provide additional advantages.

[0033] One embodiment provides that the request contains information about the user's destination. This information can be provided to the selection of motor vehicles via signaling technology, so that one advantage is that the driver of the motor vehicle can decide, based on the information about the requested destination, whether they want to accept the offer or request to take the user there. This allows the method to be improved. The destination can be entered, in particular, by the user into the interface of the communication device. The destination can be, for example, an airport terminal or a specific address.

[0034] One embodiment provides that the request includes a latest arrival time at the destination. This information can be provided via signaling to the selection of motor vehicles, so that one advantage is that the driver of the motor vehicle can decide, based on the information about the requested latest arrival time, whether to accept the offer or request to take the user there. This allows for an improved method. The latest arrival time can be entered, in particular, by the user into the interface of the communication device.

[0035] One embodiment provides that the request contains information about the number of passengers and / or pieces of luggage. This information can be provided via signaling to the selection of motor vehicles, so that one advantage is that the driver of the motor vehicle can decide, based on this information, whether to accept the offer or request to take the user there. This allows for an improved method. This information can be entered, in particular, into the interface of the communication device by the user.

[0036] One embodiment provides that the request contains information about a ride-sharing fare. This information can be provided via signaling to the selection of motor vehicles, so that one advantage is that the driver of the motor vehicle can decide, based on this information, whether to accept the offer or request to give the user a ride there. This allows for an improved method. This information can be entered, in particular, into the interface of the communication device by the user.

[0037] One embodiment provides that the forwarding of the request and / or the transmission of the acceptance takes place via a selection of base stations along a road network. In other words, the request can be forwarded from the central server device to the selection of base stations, and from the selection of base stations to the selection of motor vehicles. Alternatively or additionally, the acceptance can be transmitted from the selection of motor vehicles to the selection of base stations, and from the selection of base stations to the server device. This has at least the advantage that the communication connection between the server device and the motor vehicles can be provided in an improved manner. In particular, a wired communication connection or a wireless, indirect communication connection, for example via mobile radio, can exist between the server device and the base stations.

[0038] The electronic base stations can be arranged stationary along the road network, especially in the immediate vicinity of a road. The base stations can be evenly distributed along the road network, creating a network of base stations. A base station can, for example, correspond to a so-called roadside unit (RSU), which is permanently located, for example, on highways or federal roads.

[0039] The base stations may in particular have interfaces for communication with the server device and the motor vehicles, as well as corresponding computing units for processing the communication signals.

[0040] One embodiment provides that the selection of base stations is selected depending on a distance of a base station from the stationary communication device. In other words, a selection criterion for selecting the base stations can be that the base stations are located within a predefinable distance from the communication device. This also allows the selection to be made in a very simple, fast and effective manner. In particular, only those base stations can advantageously be addressed which are also relevant to the request for the ride sharing opportunity. In particular, the server device can be designed to select the selection of base stations according to the selection criterion. The distance can be defined, for example, as one, ten or one hundred kilometers. The distance can in particular be dependent on further information in the request, in particular a latest arrival time and a destination.The distance can be a straight line distance or a driving distance.

[0041] One embodiment provides that the selection of base stations is based on the request for a ride, in particular on the information contained in the request as already described. In other words, a selection criterion for selecting the base stations can be that one or more pieces of information in the request lie within a predeterminable range.

[0042] One embodiment provides that the request is forwarded from a base station to the selection of motor vehicles in the selection of base stations via a direct connection, in particular Car2X. In other words, the communication connection between the base station and the motor vehicle can preferably be established via a wireless direct connection, for example using Car-2-Everything (Car2X, C2X) transmission technology. This can also have the advantage that the selection of motor vehicles can be selected depending on the selection of base stations, in particular based on the range of the direct communication connection between the base station and the respective motor vehicle. A further advantage is that the motor vehicle does not need to have an interface in order to establish a mobile radio connection with the server device.

[0043] It is understood that each of the selected base stations does not have to be connected to the entire selection of motor vehicles, but rather to a corresponding subset of the selection of motor vehicles that is, for example, within radio range of the base station. The sum of the subsets can, in turn, correspond to the entire selection of motor vehicles.

[0044] One embodiment provides that the selection of motor vehicles is made depending on the distance of a motor vehicle from the stationary communication device. This can be particularly relevant if communication takes place without corresponding base stations. In other words, a selection criterion for selecting the motor vehicles can be that the motor vehicles are within a predeterminable distance from the communication device. This also allows the selection to be made in a very simple, fast, and effective manner. In particular, only those motor vehicles that are relevant to the ride-sharing request can advantageously be addressed. The distance can be defined, for example, as one, ten, or one hundred kilometers.

[0045] One embodiment provides that the selection of motor vehicles is determined depending on the request for a ride, in particular on the information contained in the request. In other words, a selection criterion for selecting the motor vehicles can be that one or more pieces of information in the request lie within a specification range of the motor vehicle. In particular, it can be provided that the motor vehicle must be specified in such a way as to be able to fulfill the request. For example, the number of users to be transported must be less than or equal to the number of passenger seats in the motor vehicle, or the trunk of the motor vehicle must be suitable for the pieces of luggage to be transported.

[0046] One embodiment provides that the selection of motor vehicles is made depending on a movement profile of the motor vehicle. For example, a selection criterion can be that the motor vehicle's direction of travel points substantially in the direction of a route between the communication device and the destination. This can be advantageous in that motor vehicles moving in the opposite direction are not queried, even if they are in the immediate vicinity of the communication device.

[0047] One embodiment provides that the selection of motor vehicles is based on the vehicle's readiness status for carrying passengers. The readiness status can, for example, be switched to active or inactive by the user, or be linked to conditions specified by the user, such as a minimum fare or the like.

[0048] For use cases or application situations that may arise during the method and which are not explicitly described here, it may be provided that, in accordance with the method, an error message and / or a request to enter user feedback is issued and / or a default setting and / or a predetermined initial state is set.

[0049] The invention also includes the control device for the motor vehicle, for the server device, the base station and / or the communication device. The control device can have a data processing device or a processor device that is configured to carry out at least steps of an embodiment of the method according to the invention. For this purpose, the processor device can have at least one microprocessor and / or at least one microcontroller and / or at least one FPGA (Field Programmable Gate Array) and / or at least one DSP (Digital Signal Processor). Furthermore, the processor device can have program code that is configured to carry out the embodiment of the method according to the invention when executed by the processor device. The program code can be stored in a data memory of the processor device. The processor device can, for example,based on at least one circuit board and / or on at least one SoC (System on Chip).

[0050] As a further solution, the invention also encompasses a computer-readable storage medium comprising program code which, when executed by a computer or computer network, causes the computer to carry out an embodiment of the method according to the invention. The storage medium can be provided at least partially as a non-volatile data memory (e.g. as a flash memory and / or as an SSD - solid state drive) and / or at least partially as a volatile data memory (e.g. as a RAM - random access memory). The storage medium can be arranged in the computer or computer network. However, the storage medium can also be operated on the Internet, for example, as a so-called app store server and / or cloud server. The computer or computer network can provide a processor circuit with, for example, at least one microprocessor.The program code may be provided as binary code and / or as assembly code and / or as source code of a programming language (e.g. C) and / or as a program script (e.g. Python).

[0051] A first aspect of the invention provides a system for providing a ride-sharing opportunity for a user in the event of vehicle damage. The system comprises at least one stationary communication device and a central server device. The at least one communication device and the central server device are particularly configured to carry out the steps of the method according to the invention.

[0052] The system can be improved and, in particular, independent of the vehicle itself, a ride can be provided to the user in the event of vehicle damage. This can be particularly advantageous if the vehicle is so damaged that it cannot provide assistance with regard to the provision of a ride. The system can help users who can no longer use the damaged vehicle to be provided with a ride quickly and easily, enabling them to reach their destination on time or at least as early as possible. By providing a ride, it can also be ensured that a driver, for example from a taxi company, does not have to be hired specifically to pick up the user.Instead, other road users who are already traveling by car can pick up the user in their car. This can be arranged so that only a small detour is required. In particular, the reduced use of motor vehicles can conserve resources and the environment. In particular, the system can be advantageous in providing unplanned, especially extremely spontaneous, ride-sharing opportunities.

[0053] Another advantage may be that the user doesn't need a smartphone or similar device to arrange a ride. This can be particularly beneficial for users whose smartphones have also been damaged or who don't own one.

[0054] The system can, in particular, comprise a plurality of communication devices, each of which is arranged stationary in a vicinity of a road, distributed across the road network. The system can also include motor vehicles or at least subsystems of the motor vehicles that are configured to carry out at least partial steps of the method according to the invention.

[0055] One embodiment provides that the system comprises at least one base station, preferably a plurality of base stations, which are signal-connected to the central server device and configured to forward the request from the central server device to a selection of motor vehicles. The base station can in particular be an RSU or the like.

[0056] One embodiment provides for the base station to be integrated into a sign gantry. This allows existing infrastructure to be used to provide the base stations, thus conserving valuable resources. Sign gantry systems are advantageously distributed substantially evenly across the entire road network. Sign gantry systems can be located, in particular, on highways or federal roads that extend over the roadway.

[0057] One embodiment provides for the stationary communication device to be integrated into an emergency call station. This allows existing infrastructure to be used to provide the communication devices. This conserves valuable resources. Advantageously, emergency call stations are distributed substantially evenly throughout the entire road network, particularly the motorway network, as well as at rest areas or relevant locations.

[0058] The invention also includes further developments of the system according to the invention that have features already described in connection with the further developments of the method according to the invention. For this reason, the corresponding further developments of the method according to the invention are not described again here.

[0059] The invention also encompasses combinations of the features of the described embodiments. The invention therefore also encompasses implementations that each comprise a combination of the features of several of the described embodiments, unless the embodiments are described as mutually exclusive.

[0060] Exemplary embodiments of the invention are described below. Shown are: Fig. 1 a flowchart of an embodiment of a method according to the invention; Fig. 2 a schematic representation of a system according to the invention.

[0061] The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that can be considered independently of one another, each of which also develops the invention independently of one another. Therefore, the disclosure is intended to encompass combinations of the features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0062] In the figures, the same reference symbols designate elements with the same function.

[0063] Fig. 1 shows a flowchart of an exemplary embodiment of a method according to the invention for providing a ride share for a user in the event of vehicle damage to the user's vehicle 9, for example due to an accident or breakdown while driving. For example, a battery of the vehicle may be damaged, resulting in its entire power supply failing. If necessary, it may be provided that the user first secures the accident scene. The user is therefore now unable to drive their vehicle and may be faced with the task of nevertheless reaching their destination on time by alternative means. In a first step S1, at least one stationary communication device 1 may be provided in the vicinity of a road 2.In particular, in the case of vehicle damage, in which driving, emergency call, and ride-sharing services may also be affected, the user can go to the stationary communication device and, in a second step S2, enter a request for a ride into the communication device due to the vehicle damage.

[0064] In a third step S3, this ride-sharing request can be transmitted from the communication device 1 to a central server device 3. In a fourth step S4, this request can be forwarded from the central server device 3 to a selection of base stations 5, 6 along a road network 7, and in a step S5, it can be forwarded from the base station 5, 6 to a selection of motor vehicles 4. The request can be forwarded from a base station 5 to the selection of motor vehicles via a direct connection 8, in particular Car2X. The selection of base stations 5, 6 or the selection of motor vehicles 4 can be selected, for example, by the server device 3 depending on the distance of a base station 5, 6 or the motor vehicles 4 from the stationary communication device 1.The selection of motor vehicles 4 can be selected alternatively or additionally depending on the request for the ride, in particular on the information contained in the request.

[0065] The request can be issued to the driver of motor vehicle 4, for example, via a user interface, whereupon the driver can decide whether to accept this request. If accepted, the driver of motor vehicle 4 can enter an input into a user interface of motor vehicle 4 in a sixth step S6.

[0066] In a seventh step S7, the acceptance of the ride-sharing opportunity can be forwarded from the motor vehicle 4 to the base station 5, in an eighth step S8 from the base station 5 to the server device 3, and in a ninth step S9 from the server device 3 to the communication device 1.

[0067] In particular, it can be provided that the driver can confirm or reject the acceptance. In the case of confirmation, the driver can be informed again about the described communication path, whereupon it can be provided, for example, that a navigation device of the motor vehicle 4 is assigned a new destination, namely the communication device 1. Consequently, the user can be picked up by the driver of the motor vehicle 4 and transported to their destination.

[0068] In Fig. Figure 2 shows a schematic representation of a system 10 according to the invention for providing a ride to a user in the event of vehicle damage. The system 10 comprises at least one stationary communication device 1 and a central server device 3, as well as optionally the base stations 5, 6 and / or the selection of motor vehicles 4.

[0069] In the example shown, the user has a breakdown with their vehicle 9 on road 2 of the road network 7. The communication device 1 can be stationed near the position at which the damaged vehicle comes to rest, for example integrated in or designed as an emergency call box 12. The communication device 1 can be signal-connected to the server device 3 via the communication link 13, for example a wired or wireless connection, e.g., mobile radio or satellite. The server device 3 can in turn be signal-connected to a plurality of base stations 5, 6 via a wired or wireless communication link 14, or alternatively to a plurality of motor vehicles 4.The base stations 5, 6, which can be integrated, for example, into sign gantries 11, can in turn communicate with the vehicles 4 via a direct connection 8, for example, using C2X communication technology. On this communication path, a user's request for a ride can be sent to relevant motor vehicles 4 in an unplanned and immediate manner, which can be accepted unplanned and immediately by the driver of the motor vehicle 4, so that the user can be quickly picked up by the driver of the motor vehicle 4 and taken to their destination.

[0070] Overall, the examples show how a car sharing option can be provided in the event of a car breakdown. QUOTES CONTAINED IN THE DESCRIPTION
