Description

Method for Determining a Route for a Vehicle as well as a Method for Performing a Cycling Mode of a Vehicle
DESCRIPTION:
The invention relates to a method for determining a route for a vehicle as well as a method for performing a cycling mode of a vehicle.
JP 2005 222527 A1 shows a chauffeur service system having a plurality of drivers wearing bell boy-like fashion so that the drivers can be recognized as drivers of the chauffeur system at a glance. Moreover, the drivers carry wireless mobile terminals.
Usually, chauffeur systems or chauffeur services are used to pick up and/or drop off people at predeterminable destinations or target locations at predeterminable times. However, it has been shown that picking up and/or dropping off people at predetermined destinations at predetermined times can be very difficult due to heavy traffic, traffic jams and/or accidents so that it is very difficult or impossible to realize adequate chauffeur services in met- ropolitan areas.
It is therefore an object of the present invention to provide a method by means of which a particularly advantageous chauffeur service can be realized.
This object is solved by a method having the features of patent claim 1 as well as a method having the features of patent claim 4. Advantageous embodiments with expedient developments of the invention are indicated in the other patent claims.
A first aspect of the present invention relates to a method for determining a route for a vehicle, in particular a motor vehicle. The method comprises receiving at least one user input by means of a device, the input being indicative of a target location and a target time. For example, the target location is a location at which the user wishes to be picked up or dropped off, wherein the target time is a time at which the user wishes to be picked up or dropped off at the target location. The method further comprises calculating a first route from a current location of the vehicle to the target location. Moreover, the method comprises calculating a first arrival time at which the vehicle is expected to reach the target location by using the first route. This means the vehicle is used to pick up and/or drop off the user at the target location at the target time. The first arrival time is a presumed time at which the vehicle would presumably reach the target location if the vehicle used or travelled along the first route.
Additionally, the method comprises determining a waiting location different from the target location and the current location. Furthermore, the method comprises calculating a second route from the current location of the vehicle to the target location, wherein the second route comprises a first route section from the current location to the waiting location. Moreover, the second route comprises a second route section from the waiting location to the target location. The method further comprises calculating a second arrival time at which the vehicle is expected to reach the target location by using the se- cond route. This means the second arrival time is a presumed time at which the vehicle would presumably reach the target location if the vehicle travelled along the second route being different from the first route.
The method further comprises choosing the first route if the first arrival time equals the second arrival time or is later than the second arrival time. The method further comprises choosing the second route if the first arrival time is before the second arrival time. When choosing the second route a waiting time the vehicle is expected to wait at the waiting location is calculated in such a way that the second arrival time corresponds to, i.e. equals the target time.
The idea behind the invention is to calculate the first and the second routes, choose the first route or the second route and calculate the waiting time in such a way that the user being at the target location can be picked up at the target time without the vehicle having to park and wait at the target location. It has been shown that, in particular in metropolitan areas, vehicles used to pick up and/or drop off people at target locations cannot park and wait at the target locations due to heavy traffic and/or the lack of parking lots. By means of the method according to the present invention the respective routes can be calculated and chosen in such a way that the vehicle does not have to wait and park at the target location but reaches the target location at the predeterminable target time so that the user can be picked up or dropped off in time. Thus, a particularly advantageous chauffeur service can be realized. For example, the car is driven by a driver using the chosen, i.e. determined route. Alternatively, the vehicle can be an autonomous car which can travel along the chosen route autonomously.
In the method according to the present invention the duration required by the vehicle to travel from the current location to the target location can be delayed by choosing the second route so that the vehicle does not reach the target location too early and does not need to wait at the target location but reaches the target location just in time. Another idea behind the invention is to delay said duration by calculating and choosing routes accordingly so that the vehicle can be moved according to speed regulations. Thus, the vehicle does not need to be moved slower or faster than a speed predetermined by a law so that annoying other traffic participants as well as illegally driving maneuvers can be avoided. In an advantageous embodiment of the invention the chosen route is presented on a display in the interior of the vehicle. Thus, an occupant, in particular the driver of the vehicle can be informed about the chosen route. Moreover, the driver can move the vehicle along the route so that the vehicle reaches the target location at the predetermined target time.
In a further advantageous embodiment of the invention the waiting time, in particular the remaining waiting time, is presented on a display in the interior of the vehicle. Thus, the driver or an occupant of the vehicle can be informed about the remaining waiting time the vehicle has to wait at the waiting loca- tion particularly precisely. Thus, the vehicle can reach the target location just in time without having to wait and park at the target location.
For example, the calculated waiting time can be set to zero (0) which means that the vehicle does not need to wait at the waiting location. Thus, for exam- pie, the vehicle just travels by the waiting location without stopping at the waiting location.
A second aspect of the present invention relates to a method for performing a cycling mode of a vehicle, in particular a rnotor vehicle. The method ac- cording to the second aspect of the invention comprises receiving a first target location. For example, the first target location is received by an input of a user which enters the first target location into a device. The method according to the second aspect further comprises determining a second target loca- tion different from the first target location. Moreover, the method according to the second aspect of the invention comprises calculating a route for the vehicle. The route comprises the first and second target locations as well as a first route section from the second target location to the first target location. Furthermore, the route of the second aspect of the invention comprises a second route section from the first target location to the second target location, wherein the second route section is different from the first route section. By travelling along the first and second route sections the vehicle can be moved from the.first target location to the second target location and back. The method according to the second aspect of the invention further comprises determining an arrival time at which the vehicle is expected to reach the first target location by travelling along the route. This means the arrival time is a presumed time at which the vehicle presumably arrives at the first target location. The method according to the second aspect of the invention further comprises transmitting the determined arrival time to a mobile device of a user who, for example, waits at the first target location. Thereby, the user can be informed about the arrival time at which the vehicle can pick up or drop off the user at the first target location. The idea behind the second aspect of the invention is that the time at which the user is to be picked up or dropped off at the first target location is unknown or not set up to new information by the user. Thus, the vehicle can cycle between the first and second target locations along the first and second route sections to minimize pick up slot time and to inform the user about the next possible slot to pick up or drop off the user. Thus, the vehicle does not need to park and wait at the first target location or the second target location since, for example, there is no possibility to park and wait. Thus, a particularly advantageous chauffeur service can be realized even in metropolitan areas with heavy traffic and/or a lack of parking lots.
In a particularly advantageous embodiment of the method according to the second aspect invention, a duration required by the vehicle to complete the route is determined. Preferably, a remaining time required by the vehicle to reach the first target location is determined so that the user can be informed about a duration the user has to wait before the vehicle reaches the target location.
In a particularly advantageous embodiment of the invention, the duration is transmitted to the mobile device of the user so as to inform the user about the waiting time. Preferably, the duration is presented on a display of the mobile device which is, for example, a mobile phone, smart phone, tablet PC or the like. In a further advantageous embodiment of the invention a third location different from the first and second target locations is determined and transmitted to the mobile device. Thereby, an event such as a traffic collapse, a traffic jam or an accident which prevents the vehicle from reaching the first target location can be considered. Thus, the third location can be used instead of the first target location so that the user can be dropped off or picked up at the third location instead of the first location.
In a further advantageous embodiment of the invention the method comprises calculating a second route for the vehicle, the second route comprising the second and third target locations as well as a third route section from the second target location to the third target location. Moreover, the second route comprises a fourth route section from the third target location to the second target location, the fourth route section being different from the third route section. Furthermore, the method comprises determining a second arrival time at which the vehicle is expected to reach the third target location by travelling along the second route. Moreover, the determined second arrival time is transmitted to the mobile device of the user so as to inform the user about the second arrival time at which the user can be picked up or dropped off at the third target location instead of the first target location. Preferably, the third location is in the vicinity of the first target location so that the user does not need to travel long distances without the vehicle.
In a further embodiment of the invention a second duration required by the vehicle to complete the second route is determined. The second duration is a cycle time used to inform the user about a duration the user has to wait until the vehicle reaches the third location.
Preferably, the second duration is transmitted to the mobile device of the user so as to inform the user about the waiting time. This means that when the vehicle cannot reach the first target location the third target location is used instead of the first target location so as to pick up or drop off the user as comfortably as possible. Further advantages, features, and details of the invention derive from the following description of preferred embodiments as well as from the drawing. The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone can be em- ployed not only in respective indicated combination but also in any other combination or taken alone without leaving the scope of the invention.
The drawing shows in:
Fig. 1 a schematic view of two routes used to illustrate a first method by means of which a particularly advantageous chauffeur service can be realized; and
Fig. 2 a further schematic view of two routes used to illustrate a second method by means of which a particularly advantageous chauffeur service can be realized.
Fig. 1 is used to illustrate a first method for determining a route for a vehicle such as a motor vehicle so as to realize a particularly advantageous chauf- feur service. In the first method at least one user input is received by means of a device. For example, the device is a mobile device such as a mobile phone, smartphone or tablet PC used to determine or set a target location 10 and a target time by the user. This means the user inputs the target location 10 and the target time into the device so that said input is indicative of the target location 10 and the target time. For example, the target location 10 is a location at which the user wishes to be picked up or dropped off at the target time by means of the vehicle. Moreover, in the first method a first route 12 from a current location 14 of the vehicle to the target location 10 is calculated. Moreover, a first arrival time at which the vehicle is expected to reach the target location 10 by using the first route as calculated. In other words, the first arrival time is a time at which the vehicle would presumably arrive at the target location 10 if the vehicle travelled along the first route 12. The calculated and presumed first arrival time depends on a first duration required by the vehicle to travel along the first route 12. Moreover, in the first method a waiting location 16 is determined, the waiting location 16 being different from the target location 10 and the current location 14. Preferably, the waiting location 16 is in the vicinity of the target location 10. Preferably, the waiting location 16 is the nearest waiting possibility to the target location 10, wherein the vehicle can park and wait at the waiting location 16.
In the first method a second route 18 from the current location 14 to the target location 10 is calculated, the second route being different from the first route 12. As can be seen from Fig. 1 , the second route 18 comprises a first route section 20 from the current location 14 to the waiting location 16. Moreover, the second route 18 comprises a second route section 22 from the waiting location 16 to the target location 10. Moreover, a second arrival time at which the vehicle is expected to reach the target location 10 by using the second route 18 is calculated. This means the second arrival time is a time at which the vehicle would arrive at the target location 10 if the vehicle travelled along the second route 18 instead of the first route 12. The second arrival time depends on a second duration required by the vehicle to travel along the second route 18 different from the first route 12. Said second duration com- prises a first sub-duration required by the vehicle to move along the first route section 20 from the current location 14 to the waiting location 16. Moreover, the second duration comprises a second sub-duration required by the vehicle to travel along the second route section 22 from the waiting location 16 to the target location 10. If the first arrival time corresponds to or is later than the second arrival time, i.e. if the first duration is equal to or longer than the sum of the two sub-durations the first route 12 is chosen so that the vehicle is moved along the first route 12 instead of the second route 18.
If the first arrival time is before the second arrival time, i.e. if the first duration is less than the sum of the two sub-durations the second route 18 is chosen so that the vehicle is moved along the second route 8 instead of the first route 12. Moreover, when choosing the second route 18 a waiting time the vehicle is expected to wait at the waiting location 16 is calculated in such a way that the second arrival time corresponds to, i.e. equals the target time. In other words, if the first arrival time is before the second arrival time the first route section 20 is used so that the vehicle is moved along the first route section 20 from the current location 14 to the waiting location 16. At the waiting location 16 the vehicle waits until the sum of the current time and the second sub-duration equals the target time so that the vehicle using the second route 18 arrives at the target location 10 at the predetermined target time.
If new information affect the second duration presumably required by the ve- hide to be moved along the second route 18 the steps of choosing one of the routes and calculating the waiting time are skipped and the method returns to the step of calculating the second route. By means of the first method the vehicle can reach the target location 10 without having to park and wait at the target location 10 and without having to exceed or be below predetermined speed limits.
Fig. 2 is used to illustrate a second method for performing a cycling mode of a vehicle, in particular a motor vehicle. In the second method a first target location 24 is received. For example, the first target location 24 is received by a device, in particular a mobile device of a user who inputs the first target location 24 into the device. For example, the user wishes to be picked up or dropped off at the first target location 24. For example, at the target location 24 there are no possibilities for the vehicle to park and wait. Thus, in the second method a second target location 26 is determined. Preferably, the se- cond target location 26 is in the vicinity of the first target location 24. Furthermore, in the second method a route 28 for the vehicle is calculated. The route 28 comprises the first and second target locations 24 and 26 as well as a first route section 30 from the second target location 26 to the first target location 24. Moreover, the route 28 comprises a second route section 32 from the first target location 24 to the second target location 26, the second route section 32 being different from the first route section 30.
Moreover, in the second method an arrival time at which the vehicle is expected to reach the first target location 24 by travelling along the route 28 is determined. When the vehicle is moved along the route 28 the vehicle cycles between or around the target locations 24 and 26 without intentionally stopping at the target locations 24 and 26. In order to inform the user about the time at which the vehicle will presumably arrive at the first target location 24 the determined arrival time is transmitted to a mobile device of the user. Thus, the user can be informed when the vehicle will arrive at the target location 24 the next time. Moreover, a duration required by the vehicle to complete the route 28 is determined, wherein the duration is transmitted to the mobile device so as to inform the user how long it takes the vehicle to cycle, i.e. to complete the route 28 once. Preferably, the duration is a remaining time showing the user how long they have to wait until the vehicle reaches the target location 24 the next time.
For example, if the vehicle is expected to not be able to reach the target loca- tion 24, a third target location 34 different from the first and second target locations 24 and 26 is determined and transmitted to the mobile device. Preferably, the third target location 34 is in the vicinity of the first target location 24. Moreover, a second route 36 for the vehicle is calculated, wherein the second route 36 comprises the second and third target locations 26 and 34 as well as a third route section 38 from the second target location 26 to the third target location 34. Moreover, the second route 36 comprises a fourth route section 40 from the third target location 34 to the second target location 26, the fourth route section 40 being different from the third route section 38. Furthermore, a second arrival time at which the vehicle is ex- pected to reach the third target location 34 by travelling along the second route 36 is determined and the determined second arrival time is transmitted to the mobile device of the user.
For example, if the first target location 24 is blocked for the vehicle due to a traffic collapse, traffic jam or an accident the third target location 34 in the vicinity of the first target location 24 is used instead of the first target location 24. Thus, for example, the user can be picked up or dropped off at the third target location 34 instead of the first target location 24. By transmitting the second arrival time to the mobile device the user can be informed about the time at which the vehicle will presumably arrive at the third target location 34 the next time. Preferably, a second duration presumably required by the vehicle to complete the second route 36 is determined, wherein the second duration is transmitted to the mobile device so as to inform the user how long they have to wait until they can be picked up or dropped off by the vehicle at the third target location 34.
As can be seen from Figs. 1 and 2 a particularly advantageous chauffeur service can be realized by means of the methods even in metropolitan areas since the respective vehicles do not need to park and wait when picking up or dropping off people, i.e. the users. Thus, the respective user can be picked up or dropped off in a particularly comfortable way without causing traffic law violations and traffic incidents.
