Abstract

Method for providing a notification signal (S) to be transmitted to at least one occupant (I1) of a vehicle (1) in relation to the occupant (I1) reaching a predetermined destination via a notification system (10), wherein the vehicle (1) is one of several occupants (I1, I2, I3, I4) with respectively predetermined, in particular at least partially different, travel destinations can be used jointly, the notification system (10) being suitable and intended for providing a large number of different types of notification signals (S). According to the invention, a notification signal (S) is selected from a large number of different types of notification signals suitable for notifying the occupant (I1) on the basis of at least one other occupant (I2, I3, I4) of the vehicle (I2, I3, I4) of the vehicle ( 1).

Description

The present invention relates to a method and a notification system for providing a notification signal, which is to be transmitted to an occupant of a vehicle used by a plurality of occupants, in relation to the occupant having reached a predetermined travel destination. In particular, the present invention relates to notification, preferably silent, to occupants of a shared vehicle. The notification system is suitable and intended for providing a large number of different types of notification signals, such as acoustic and/or visual notification signals.

In situations such as shuttle service, carpooling or ride-sharing, several people use a vehicle to get to their personal destination. In the best case, the respective destinations are on one route. In this way, people are dropped off one after the other at their destination. To do this, it is sometimes necessary to inform the occupant that the destination has been reached (similar to an announcement on public transport), with the respective destination in ride-sharing operation often only being relevant for one occupant.

Methods and notification systems for providing a notification signal to occupants of a shared vehicle have long been known from the prior art. Acoustic messages such as announcements or warning tones are used to draw the attention of occupants to an approaching destination.

It is also known to inform the occupants via visual messages such as a display or light that a destination will be reached (soon). Here, however, there is the disadvantage that these messages are perceived by all occupants and can be perceived as annoying.

From the JP 2016 016674 A An arrival notification system for a train is known, which informs the passengers by means of a vibration device on their seat that the destination is about to be reached.

In the U.S. 2019/0300020 A1 a seat is proposed, for example for an automobile, which can transmit a large number of haptic signals to the user. For example, it can be provided to announce an approaching bus stop to a user of a bus with a slight “nudge”.

From the DE 10 2018 126 721 A1 a notification system is known which can provide an audible and/or haptic alert to a passenger of a vehicle as a wake-up notification based on a distance or time period until the vehicle reaches the passenger's destination. Provision is also made for an acoustic notification to be transmitted to the passenger by means of a localized audio signal.

The notification systems and methods for providing a notification signal that are currently known from the prior art have the disadvantage that the notifications, even if they are only addressed to individual occupants, may be noticed by other occupants and are perceived as annoying be able.

The present invention is based on the object of overcoming the disadvantages known from the prior art and of providing a method and a notification system for providing a notification signal to at least one vehicle occupant, which offers the most pleasant and quiet driving experience possible for all vehicle occupants and at the same time in a reliable manner can inform an occupant that their destination will be reached soon.

The object is achieved according to the invention by the subject matter of the independent claims. Advantageous embodiments and developments of the invention are the subject matter of the dependent claims.

In a method according to the invention for providing a notification signal to be transmitted to at least one occupant of a vehicle in relation to the occupant reaching a predefined travel destination via a notification system, the vehicle is (at least temporarily) ) can be used together. This is preferably a vehicle that is suitable for shared use. In particular, several people or occupants use the vehicle in order to reach (sometimes) different travel destinations. The vehicle preferably collects a number of people at possibly different locations.

In this case, the notification system is suitable and intended to provide a large number of different types of notification signals. For example, it can be an acoustic, an optical and/or a haptic notification signal.

According to the invention, a notification signal is selected from a large number of different types of notification signals suitable for notifying the occupant on the basis of an (in particular potential) disturbance to the rest of at least one other occupant of the vehicle caused by at least this notification signal.

In other words, at least one (for the occupant to be notified) individualized notification signal is provided. For example, just before arriving at the destination, a specific person (the occupant to be notified) is notified that the destination will be reached shortly.

The provided notification signal is preferably output to the at least one (occupant to be notified). Preferably, the notification signal (issued) is physically perceivable by the occupant (to be notified). Preferably, the (issued) notification signal can only be physically perceived by the occupant or occupants to be notified. In other words, the notification signal with which the (at least one) occupant is to be notified should preferably not be physically perceptible (or at least not in a way perceived as disturbing) by another occupant and in particular one who is not to be notified.

This offers the advantage that other occupants are not disturbed by this. This ensures a more pleasant and relaxing driving experience, which is of great importance, especially on longer journeys and/or driving at night. For example, it is suggested that the (issued) notification signal is a silent notification signal. Advantageously, other occupants are not disturbed by the proposed silent messages.

A notification signal (and in particular each of these notification signals) can be provided for the occupant and preferably for each occupant individually and independently of one (in particular each) other occupant and (in particular exclusively) output directly to this occupant.

Two different types of notification signals are understood to mean, in particular, notification signals which the occupant can perceive in at least one different way from one another, for example by (at least one different) sense of perception being addressed. For example, one notification signal can be perceived acoustically or visually and the other notification signal can be perceived haptically and/or tactilely. Notification signals that differ from one another are preferably output by at least one output device of the notification system that is different from one another and preferably spaced apart from one another (and in particular by output devices (of the notification system) that are different from one another in each case.

However, it is also conceivable that two different types of notification signals differ in terms of their directional characteristics and/or emission characteristics. For example, one notification signal could be a non-directional signal and the other signal, which has different directional characteristics, could be a directional signal. For example, a larger solid angle or interior area (of the motor vehicle) could be illuminated by one lighting device than by a further lighting device that illuminates, for example, a comparatively narrower solid angle or spatial area. For example, a light signal or an optical notification signal could advantageously only be displayed for the respective person. The notification signal is preferably output locally (for at least one and preferably exclusively for the person to be notified), with this preferably being perceptible only by the occupant to be notified or by the occupants to be notified.

Furthermore, the area of perception of the issued or transmitted notification signal can also be different from that of another (in particular different) notification signal. For example, a haptic (vibration) notification signal can be output or transmitted to an occupant from a seat, a seat belt tensioner or a mobile device (such as a smartphone or a smartwatch), but these differ from one another in their range of perception.

Preferably, two different types of notification signals can also be distinguished by a characteristic property of the notification signal, such as a frequency range or at least one frequency, a color, or by a type of sound event to be perceived, such as noise, tone, tone.

Furthermore, different types of notification signals can be distinguished by their signal direction and/or their signal strength (e.g. volume, brightness, etc.) and/or an output pattern of the signal (such as a predetermined sequence of signal repetitions or variations at predetermined time intervals). However, it is also conceivable that differences in the signal strength and/or output pattern are not interpreted as different types of notification signals.

A notification signal to be transmitted in relation to the occupant reaching a specified destination is preferably understood to mean that the provision of the notification signal is related in terms of time and/or location to the (expected and/or actual), in particular imminent, achievement of this destination, in particular in Depending on an (expected) remaining driving time and/or remaining driving distance. The notification signal is preferably provided when the occupant to be notified is approaching the destination.

Each person boarding preferably indicates the desired destination (or destination) in advance, for example when booking or when boarding. The notification system and/or the vehicle, in particular a control device of the vehicle, preferably calculates a route from the pick-up locations and destinations (or travel destinations) and drops the people or occupants at the (specified) destinations. The pick-up locations and destinations (or travel destinations) can be identical for the occupants (in particular in pairs) or different (in particular also in pairs, but also partially).

Preferably, a pick-up location for (in particular each) occupant can be defined flexibly and individually and can particularly preferably be specified and adjusted (for example via a mobile terminal device such as a smartphone) by the occupant himself. Likewise, a travel destination (or destination) of (in particular each) occupant can preferably be specified flexibly and individually and can particularly preferably be specified and set (for example via a mobile terminal device such as a smartphone) by the occupant himself. The pick-up location and/or the destination (or destination) is preferably transmitted to the notification system and/or to the vehicle and/or to a navigation device of the vehicle (such as a navigation device) and in particular in a storage device (of the notification system of the vehicle and /or the navigation device). The navigation device is preferably suitable and intended for determining a route for the vehicle on the basis of at least one pick-up location and/or at least one destination and preferably on the basis of a large number of pick-up locations and/or a large number of destinations (one or more occupants) and/ or to calculate. The route can be optimized and/or calculated as a function of a (current or expected) traffic situation and/or a (specified) route selection (shortest/fastest route).

The notification system and/or the navigation device is/are preferably suitable and determined for determining and/or determining a current position of the vehicle. The notification signal is preferably provided and/or output as a function of the (determined) current position of the vehicle.

Driving destination can be understood not only as an intended end destination of an occupant but also as an intermediate destination of the occupant.

The driving route of the vehicle (in particular its spatial course) of the vehicle is preferably not fixed (or rail-bound) and cannot be changed (although this is also possible), but can be changed by a travel destination desired by at least one occupant and/or a pick-up location and/or or impressionable. The pick-up time and/or the point in time at which the travel destination is to be reached can preferably also be influenced, specified and/or set by at least one occupant or by a plurality of occupants.

In a preferred method, a travel destination and/or a remaining distance and/or a remaining travel time of at least one other occupant is taken into account in the selection. This offers the advantage that in this way it can be taken into account whether occupants who do not need to be notified for the next destination want to get off at the next but one destination and would have to be notified for this in a close temporal context anyway or whether a notification signal would have to be provided to them. Advantageously, therefore, an assessment can be taken into account of the effects of any disruption to the rest of another occupant caused by the output of the notification signal and/or the benefit of avoiding or reducing the disruption to rest caused by the notification signal for the other occupant.

For example, if all remaining passengers have to disembark at the next stop and some passengers are asleep, it is preferable to choose a type of notification that effectively informs all passengers, e.g. B. a combination of haptic and audio-visual information.

In a more preferred method, a number of other occupants are included in the selection and/or whose physical proximity to the occupant to be notified is taken into account, in particular whose destination matches the specified destination of the occupant to be notified and/or is within a specified distance of this.

During the selection, all occupants of a vehicle (or a cabin/compartment of the vehicle) (or an impairment of their rest) can be taken into account. However, it is also conceivable that not all other occupants of a vehicle are taken into account in the selection. It is conceivable that only (directly) neighboring further occupants are taken into account in the selection. In the selection, preferably only other occupants within a specific, predetermined radius (such as within 3 m, preferably at most 2 m, preferably at most 1 m from the occupant to be notified) are taken into account. In particular, occupants who are further away already receive a weaker notification signal anyway. It is preferably determined, for example via an (optical) detection device, whether and how many other occupants are present in a specific, predetermined area. Preferably, only the next 10 other occupants, preferably the next 5 other occupants, preferably the next 3 other occupants, preferably the next 2 other occupants and particularly preferably only the next-door occupant (in each case opposite the occupant to be notified) are taken into account in the selection.

In a further preferred method, the selection depends on a physical condition and/or on a level of alertness of at least one other occupant, with a current physical condition and/or the level of alertness preferably being determined via a (particularly optical) detection device, such as at least one (interior )camera, is captured. The physical state and/or state of alertness can be, for example, a state of being awake, a state of sleep or, for example, dozing.

If some/all passengers or occupants are sleeping (e.g. determined from interior cameras) and only a few passengers have to get off at the next stop, a silent form of notification is preferably selected.

In particular, the selection (of the notification signal) can depend on a recording captured by at least one interior camera and/or on at least one noise and/or noise level captured by (at least) one microphone. The selection can preferably depend on at least one sensor or multiple sensors (of the vehicle and/or the notification system), the current values of which depend on the (current) activity and/or sitting position and/or posture and/or the physical condition of an occupant.

Furthermore, the degree of an activity can be taken into account. Thus, in the case of a lively (and loud) conversation, a notification signal can advantageously be selected which is also (usually) easily perceptible in such a conversation. For example, a combination of several notification signals, such as a combination of haptic and audio-visual notification signal, would be conceivable. However, it is also conceivable that the signal strength of the notification signal is adjusted.

A (specified) preference of the occupant to be notified is preferably taken into account in the selection. If, for example, a number of notification signals are still available when the (potential) disturbance to the rest of the other occupants is taken into account, a predefined preference of the occupant to be notified can be taken into account. However, it is also conceivable that the selection does not (only) depend on an occupant-specific preference, but on a predetermined, occupant-independent sequence of different notification signals. It is preferably checked (in particular initially or as a first step in the selection process) (by the notification system) whether a silent notification signal is possible and/or leads to an impairment of the rest of another occupant.

The selection is preferably dependent on a (current) actuation state and/or body posture of the occupant to be notified and/or at least one other occupant. An actuation state can be, for example, a current activity, such as observing the surroundings through a window, reading, watching a video, listening to music, making a phone call, looking at a screen (laptop, smartphone, etc.). For example, if the occupant to be notified is currently busy with a smartphone, a vibration notification signal, which is transmitted by the latter, can preferably be selected. Furthermore, for example, an optical notification signal can be selected if a neighboring occupant (anyway) is looking straight out of the window and the notification signal cannot be perceived in this viewing direction. The (current) actuation state and/or body posture is preferably recorded by a (in particular optical) detection device (of the Benach correction system), such as B. at least one vehicle interior camera detected.

In a further preferred method, a geometric property of the vehicle interior and/or a seat occupancy (predetermined in particular or detected by an (optical) detection device) is or are taken into account in the selection. This offers the advantage that a weakening or damping of the notification signal caused by a geometric property of the vehicle interior is already sufficient to provide a predefined notification signal for the desired quiet for the other passengers.

One or more seat occupancy sensors can also be used and evaluated to determine seat occupancy. For this purpose, the data measured by a seat occupancy sensor can be transmitted to the notification system. At least one seat occupancy sensor can (respectively) be arranged in or on a (vehicle) seat. A seat belt sensor can preferably also be used as the seat occupancy sensor, which can in particular determine whether the seat belt is in a released or locked state.

A seat occupancy of the vehicle can preferably be determined (at least in certain areas and preferably completely) from driving data that is predefined and/or stored (in particular in a memory device of the notification system and/or the vehicle) and/or transmitted by one or more occupants. A comparison can preferably be made with the data determined by at least one seat occupancy sensor in order to determine whether the seat specified in the driving data and/or the seat matches the current seat of an occupant.

A seat occupancy is preferably determined by locating (in each case) a mobile end device of one or more occupants.

The geometric type of the vehicle interior can be, for example, the arrangement of at least one vehicle seat, in particular a backrest, or other sound-damping or light-shielding elements or surfaces opposite the output device which emits the notification signal. Furthermore, a seat occupancy (instantaneous and/or present at the time the notification signal is output) can preferably be taken into account in the selection. The arrangement of the occupant to be notified in relation to at least one and preferably to a plurality of other, in particular neighboring, occupants can be taken into account. In addition, it is preferably taken into account whether the two occupants and/or seats assigned to them are placed next to one another (for example in a row of seats, preferably directly next to one another and/or one behind the other (for example in adjacent rows of seats).

In a further preferred method, a predefined notification signal is provided independently of other occupants as a function of a physical condition of the occupant to be notified, in particular a physically impaired condition. This offers the advantage that, depending on a predetermined physical condition of the occupant, an efficient notification is given priority over any impairment of the rest of another occupant.

If, for example, it is known, in particular from the passenger data, that a certain type of information (or a certain type of notification signal) cannot be successful, such as with deaf and/or blind passengers), this is preferred when selecting the information method or The type of notification signal is taken into account, in particular if another passenger or occupant could then be disturbed.

If only one suitable notification signal is available due to an in particular predetermined physical condition of the occupant to be notified, this notification signal is preferably provided independently of other occupants and in particular output to the occupant to be notified. The suitability of a notification signal is dependent on a, preferably predetermined, physical condition of the occupant to be notified. In the case of a deaf patient, for example, an acoustic signal is unsuitable.

The notification system can also determine, in particular via at least one detection device, the current state of an occupant who is to be notified. For example, it can be recognized (automatically) when an occupant falls asleep.

A status determination device can preferably be provided as the detection device, which preferably determines a status of one or more occupants by examining the eye reactions and/or eye activities. The notification signal is preferably selected on the basis of one or more of these determined states. The status determination device is preferably additional Lich or alternatively suitable and intended to determine the state of one or more occupants from sleeping noises recorded by means of a microphone and/or other noises. It is also conceivable that pulse rate information and/or movements of an occupant's arm, which are determined and recorded by an occupant's smart watch, for example, can be used to draw conclusions about the condition of an occupant and take them into account in the selection. It would also be conceivable for the notification system to infer a status and/or an activity of the occupant via a determined data traffic between a mobile terminal device of an occupant and a network provided locally in the vehicle (such as a radio network).

In a further preferred method, the notification signal is selected from a group comprising silent notification signals, haptic notification signals, optical notification signals, acoustic notification signals and combinations thereof.

The notification signal is preferably output via an output device and/or transmitted to the occupant to be notified. The output device can be an HMI (“Human Machine Interface”). This can have an optical display device (for example a display), a loudspeaker, a lighting device (for example light-emitting diodes, ambient light, smart light) and/or a vibration device.

In a further preferred method, the notification signal is sent via a contact element of the vehicle (which contacts the occupant to be notified), in particular a seat and/or a belt tensioner, via a mobile device (e.g. laptop, smartphone, smartwatch) and/or via output an optical display device.

A haptic message can be sent via the seat, for example. The seat vibrates until the person confirms the message. This ensures that the person has registered that the destination will be reached shortly.

The notification signal is preferably output or transmitted when the seat belt tensioner of the respective occupant is tightened, for example at small intervals.

A visual message or a visual notification signal can be displayed as local information text (e.g. on a personal display) or as a light signal that is only visible to the person in question. If necessary, light signals can be combined with ambient light and/or smart light.

The notification signal is preferably output with a signal strength (such as volume) and/or directional characteristic adapted to the condition of at least one or more occupants and/or to at least one environmental factor (such as ambient noise). For example, light that shines directly on an occupant's face is usually perceived as disturbing, whereas subdued and darkened (and indirect) light is usually perceived as less disturbing.

The contact element via which the notification signal is to be output is preferably selected on the basis of a recording of the occupant (to be notified) taken by an (optical) detection device. For example, it can be determined via which contact element the occupant can be woken up or notified more efficiently.

Provision can be made for the notification signal to be provided in a predetermined period of time (fixed or selectable by the respective occupant and in particular input via a mobile terminal device) before the expected arrival at the destination. For example, the notification signal can last for at least 30 minutes, preferably at least 20 minutes, preferably at least 10 minutes, preferably at least 5 minutes and/or at least 2 minutes and/or at most 30 minutes, preferably at most 20 minutes, preferably at most 5 minutes and/or preferably at most Provided 2 minutes before (expected) arrival and preferably handed out to the occupants. This selected period of time can depend on the total driving time of the occupant and/or the total driving distance and/or other factors (such as any luggage present or the number of occupants who are also getting out).

Alternatively or additionally, provision can be made for the notification signal to be provided at a (fixed or selectable by the respective occupant and in particular inputable via a mobile terminal) predetermined (spatial) distance from the destination. The notification signal can be at least 100 m, preferably at least 500 km, preferably at least 1 km, preferably at least 5 km and/or at least 10 km and/or at most 30 min, preferably at most 10 km, preferably at most 5 km, preferably at most 1 km and/or preferably provided at most 500 m before (expected) reaching and preferably issued to the occupant will give. This selected time period can depend on the total travel time of the occupant and/or the total travel distance and/or other factors (such as any luggage present or the number of occupants who are also getting out).

The present invention is also directed to a notification system for a vehicle for providing a notification signal to be transmitted to at least one occupant of the vehicle in relation to the occupant reaching a specified destination, the vehicle having a plurality of occupants each with specified, in particular at least partially different, occupants , Destinations can be used together, the notification system being suitable and intended to provide a large number of different types of notification signals.

According to the invention, the notification system is configured such that a notification signal is selected from a large number of different types of notification signals suitable for notifying the occupant based on at least one other occupant of the vehicle being disturbed by at least this notification signal.

The notification system is preferably set up, suitable and/or intended to carry out the method described above and all the method steps already described above in connection with the method individually or in combination with one another. Conversely, the method can be equipped with all of the features described in the context of the notification system, either individually or in combination with one another.

It is therefore also proposed within the scope of the notification system according to the invention that - if several notification signals are available for the occupant to be notified (for efficient transmission or notification or for waking up) - in particular the status of another occupant and preferably the respective status of several inmates is taken into account in the election. In this way it can be advantageously achieved that the quietness affects as few occupants as possible and thus a driving experience that is as pleasant as possible can be achieved for as many occupants as possible.

The present invention is also aimed at a vehicle, in particular a motor vehicle, comprising a notification system for a vehicle according to one of the embodiments described above. The notification system can be equipped with all of the features described above in connection with the notification system, either individually or in combination with one another. The vehicle can be controlled by a driver or drive autonomously. The (road) vehicle is preferably set up and intended to carry out the method for providing a notification signal.

The output device is preferably arranged (in particular fixed) on the vehicle and in particular in an area and/or on a vehicle seat or place of the occupant to be notified. The vehicle preferably has at least one (own) and preferably a large number of (own) output devices for each (vehicle) seat and/or place that is assigned to or provided for an occupant (to be notified during the journey).

Alternatively or additionally, the output device can be a mobile (terminal) device, in particular of the occupant, which is preferably integrated into the notification system.

The vehicle can in particular be any vehicle that is suitable for shared use, such as a shuttle, a bus, a (road) vehicle used for carpooling or ride-sharing. The vehicle can be a motor vehicle, in particular a motor vehicle controlled by the driver himself (“driver only”), a semi-autonomous, autonomous or self-driving motor vehicle. The vehicle can also be a driverless transport system. In addition to a road vehicle, the vehicle can also be an air taxi, an airplane and another means of transportation or another type of vehicle, for example an air vehicle, water vehicle or rail vehicle.

The present invention of the method for providing a notification signal to be transmitted to a person and a corresponding notification system have been described in connection with a vehicle and in relation to a destination to be reached. However, the present invention can also be transferred to other facilities in which several people are waiting for an event which, however, may not affect everyone. The applicant reserves the right to also claim a method and notification system aimed at this.

The present invention is also directed to a computer program or computer program product, comprising program means, in particular a program code, which at least at least represents or encodes the method steps of the method according to the invention and preferably one of the described preferred embodiments and is designed to be executed by a processor device.

The present invention is also aimed at a data memory on which at least one embodiment of the computer program according to the invention is stored.

Further advantages and embodiments result from the attached drawing:

• 1 a schematic plan view of a motor vehicle with a notification system according to the invention according to one embodiment.

1 shows a schematic plan view of a motor vehicle 1 with a notification system according to the invention according to one embodiment. The motor vehicle has a multiplicity of seats. The reference symbols I1, I2, I3, I4 each identify an occupant who uses the motor vehicle to travel together. The reference number 10 schematically designates the notification system of the motor vehicle, via which the occupant I1 is to be informed or notified here that his desired travel destination will soon be reached or approached.

For this purpose, the notification system can provide an acoustic notification signal S, for example, which is transmitted or output to the occupant I1. If all other occupants I2, I3 and I4 also have to get out at this destination or already at the next stop, the disruption to the rest of the other occupants I2, I3 and I4 caused by the acoustic notification signal S can be accepted or even desired.

But if, for example, the other occupant I2 still has a longer journey ahead of him, he should not be disturbed by the output of the (acoustic) notification signal S, if possible, in order to offer him a pleasant and relaxing driving experience.

In this case, the notification system 10, in particular a processor device thereof, can make a selection from a large number of different types of notification signals S, which can also be provided in order to notify the occupant I1. A notification signal is therefore preferably selected as a function of the travel destination and/or the remaining travel time, here for example the other occupant I2, which disturbs the rest of the occupant I2 less than an acoustic signal. For this purpose, for example, as shown here, a display can be provided as the optical output device 12, which is arranged in the area of the seat of the occupant I2. An optical notification signal can be output to the occupant I1 via this optical output device, and the latter can be informed that the vehicle is about to arrive. However, a vibration signal would also be conceivable, for example via a seat surface and/or backrest and/or armrest.

Reference number 14 designates a seat occupancy sensor which is or can be connected to notification system 10 for data transmission. The notification system can use the seat occupancy sensor to detect which seat is occupied and whether, for example, seats that are adjacent to the occupant I1 reporting the notification are occupied. Using the data recorded by one or more seat occupancy sensors, a seat occupancy of the vehicle can be determined (at least partially or completely), based on which a notification signal can be selected, by means of which the occupant I1 to be notified is informed.

The applicant reserves the right to claim all features disclosed in the application documents as essential to the invention, provided they are new compared to the prior art, either individually or in combination. It is also pointed out that the individual figures also describe features which can be advantageous in and of themselves. The person skilled in the art recognizes immediately that a specific feature described in a figure can also be advantageous without adopting further features from this figure. Furthermore, the person skilled in the art recognizes that advantages can also result from a combination of several features shown in individual figures or in different figures.
