Method for notifying a user of a vehicle, control and

vehicle

The invention relates to a method for notifying a user of a vehicle, a controller that executes such a method and a vehicle with such a controller.

In general, it is known to transmit push messages via SMS (short message service) or other Internet or cloud services to a user or his end device, in order to inform the user, for example, of the condition of a motor vehicle.

For example, it is known from US Pat. No. 9,108,561 A2 to remind a user of a motor vehicle to connect a charging plug to charge a battery of the vehicle when it is recognized that the user wants to leave the vehicle.

US 2015/0378315 A1 describes wirelessly communicating with a portable device in order to remind a user that a specific time interval is set for an electrical charging process of a vehicle. This reminds the user that he

Take action if he wants to charge the vehicle's battery outside the set time interval.

From US 8,718,844 B2 it is known to inform a user by phone call or in writing by email or text message that the battery of a vehicle has to be charged.

A charge control for an electrical energy store is known from DE 10 2013 007 525 A1. Here, a charging time is output on a navigation device, at which the electrical energy storage device of a vehicle must be charged. This data can also be transmitted wirelessly to a smartphone or a PDA (personal digital assistant).

According to the solutions of the prior art, a user is informed about the need to charge an electrical energy store, but the ones discussed Solutions have the disadvantage that they do not foresee in advance that a charging process may be necessary and inform the user accordingly.

The object of the present invention is to provide a method, a control and a vehicle which at least partially overcome the disadvantages mentioned above.

This object is achieved by the inventive method according to claim 1, the controller according to claim 14 and the vehicle according to claim 15.

According to a first aspect, the present invention provides a method for notifying a user of a vehicle with at least one electrical energy store, comprising:

Determining a location of the vehicle,

Determining a charging condition of the electrical energy store,

Determining a position of the user of the vehicle, and

Transmitting a message to a mobile device of the user depending on the determined location, the determined loading condition and the determined position of the user.

According to a second aspect, the present invention provides a controller for a vehicle with at least one electrical energy store, the controller being set up to carry out the method according to the first aspect.

According to a third aspect, the present invention provides a vehicle with at least one electrical energy store and a controller according to the second aspect.

Further advantageous refinements or aspects of the invention result from the subclaims and the following description of preferred exemplary embodiments of the present invention.

A method according to the invention for notifying a user of a vehicle with at least one electrical energy store comprises:

Determining a location of the vehicle,

Determining a charging condition of the electrical energy store,

Determining a position of the user of the vehicle, and

Transmitting a message to a mobile device of the user depending on the determined location, the determined loading condition and the determined position of the user. The vehicle can be a vehicle, such as a car, a truck, a bus or the like, but it can also be an aircraft, an industrial truck or the like. The vehicle may have an electric machine for driving, some of them

Embodiments the vehicle is designed as an electric vehicle, in others as a (plug-in) hybrid vehicle.

The vehicle has at least one electrical energy store, for example a battery

(Accumulator), which are provided, for example, as energy stores for the (at least one) electric machine. However, the electrical energy store can also have a plurality of stores (batteries, battery cells) and, for example, also comprise one (or more) capacitor (s) or other electrical energy storage means.

The method comprises determining a location of the vehicle, this location being determined, for example, by means of a global navigation satellite system (for example GPS, global positioning system, GLONASS, Galileo or the like) or also based on other known means, for example. Determination by triangulation in a mobile radio system, radio cells in a mobile radio system, by means of signal strengths in wireless networks, etc.

The location of the vehicle can be determined absolutely (e.g. by global

Coordinates) and / or relative to a position, e.g. B. to a charging station, building, street, etc.

The method also includes determining a charging condition of the electrical

Energy storage so that, as explained below, conditions that must be present for a charging process can be checked. However, the charging condition can also include, for example, the state of charge of the electrical energy store and the like.

The method also determines a position of the user (e.g. the driver or

Driver) of the vehicle, whereby this position can be specified absolutely (e.g.

global coordinate), or also relative, e.g. B. determined in relation to the vehicle or

can be specified.

Finally, a message is transmitted to a user's mobile terminal (PDA (personal digital assistant), mobile phone (also smartphone), portable computer, pager or the like), assuming that the user carries the mobile terminal with him when he leaves the vehicle. The message is transmitted depending on the determined location, the determined loading condition and the determined position of the user.

As a result, in some exemplary embodiments, a link can be established between the distance or direction of the user to the vehicle, the function (high volt) - charging of the electrical energy store being taken into account.

In addition, a distance and / or (movement) direction of the user from the vehicle to interesting points (pols, point of interests) in the (closer) surroundings of the

Vehicle are evaluated and taken into account together with, for example, data relevant to charging, charging plans, calendar entries of the user, and the charging conditions.

Furthermore, the user can be informed when they are removed from the vehicle, for example if there is a request for charging or if the electrical energy storage device (e.g. HV battery) would have to be charged for the next trip, but charging does not start or cannot start (i.e. the

Charging condition is not met accordingly).

This can result in a time delay in the case of some execution examples

Avoid messaging.

In some exemplary embodiments, messages can also be transmitted to the user, in particular in the case of a non-existent (mobile radio) network (e.g. due to network failure, lack of network coverage, network congestion) (e.g. because in some exemplary embodiments a wireless communication path is used which is independent of a cellular network).

Even with changing environmental conditions, e.g. B. T emperature change and thus changing state of charge of the electrical energy storage, resulting in a reduced

Range, messages can be transmitted to the user (or his mobile device).

In addition, in some exemplary embodiments, prompt transmission of the message can prevent the user from recognizing, for example, later in his apartment at his place of work or the like, that he should have started charging the (HV) battery, or that charging ( preconditions) are not met and charging cannot take place, for example, despite a charging request. In such a scenario, it can be avoided, for example, that the Users have to go to the vehicle again and insert the charging plug or meet other charging conditions so that charging can take place.

In addition, in some exemplary embodiments it is possible that, for example, a

Emergency communication is provided in the event of a failed or impending failure of the (mobile) network, so that all "last" and "saving / important" messages to the user, e.g. B. transmitted when leaving the vicinity of the vehicle.

Determining the position of the user can include determining a distance between the user and the vehicle. This has the advantage that it can be determined whether the user is approaching or moving away from the vehicle, so that, for example, messages can be transmitted as long as he is still at a certain distance from the vehicle or, if it is recognized, that the user is nearby of the vehicle remains, ie has no intention of moving further away from the vehicle, the communication is omitted.

Accordingly, it can be provided that the message is transmitted to the mobile terminal when the distance exceeds a predetermined threshold value. The message can thus be transmitted to the user (his mobile terminal device) when he is away from the vehicle, but is, for example, still close enough to the vehicle so that, for example, he is still in the catchment area of a near-field communication area.

The determination of the position of the user can also include the determination of a direction of movement of the user and the message can then be transmitted to the mobile terminal depending on the determined direction of movement. It is also determined here, for example, that the user wants to move away from the vehicle, e.g. B. to an interesting point (see also below), such as his apartment, his workplace, supermarket, restaurant, coffee, tourist attraction, bus, train, etc.

The position of the user can be determined in a variety of ways. On the one hand, the mobile terminal (or another mobile terminal) can provide a position determination and transmit it wirelessly to the vehicle (central control), for example. Mobile devices known today are able, for example, to carry out an absolute position determination using appropriate sensors (e.g. GPS). In addition, wireless radio signals can also be evaluated, such as, for example, Bluetooth (or BLE), wireless LAN (wireless network), mobile radio signals or the like, which are made possible by triangulation and / or Signal strength measurements or other known techniques to perform a distance measurement and / or direction measurement.

In addition, in some embodiments, the vehicle is equipped, one

To carry out position measurement (distance and / or direction of movement) of the user, for example by providing optical sensors, infrared sensors, distance sensors, etc., which recognize the user and his position directly without any further means (mobile terminal, radio transmitter or the like) is needed.

In some exemplary embodiments, a keyless system is also provided, in which, for example, the user carries a radio transmitter (key, key card or the like) with him, which transmits / receives, for example, in the UHF band or RFID range. The vehicle is equipped with a number of radio antennas, the distance and / or the (movement) direction of the radio transmitter and thus of the user wearing it being able to be determined based on the different signal strengths measured on the radio antennas.

In some embodiments, the environment or the exterior of the

Vehicle can be divided into different areas, so that it can be determined, for example, in which area the radio transmitter (and therefore the user) is located and how it is moving and what distance it is from the vehicle.

Thus, in some embodiments, the position of the user stands as a distance and / or polar coordinates ((movement) direction), e.g. B. in relation to the vehicle. It can also be used to determine whether the user is approaching the vehicle or whether he is moving away, etc.

Furthermore, different areas around the vehicle can be recognized, for example by means of distance threshold values, in which, for example, B. the radio transmitter is located or penetrates into it or leaves it. Such areas can be linked, for example, to a charging socket of the vehicle, the driver's side, the doors, trunk, hood, etc. The threshold values can also be set individually for each area.

In some exemplary embodiments, this also determines whether the user is close to the vehicle, the proximity to the vehicle being adaptable, and, for example, not only being able to be defined directly by an input, but can also be learned or adapted on the basis of user behavior. In some exemplary embodiments, the charging condition includes a charging precondition and / or a state of charge of the electrical energy store, the charging precondition comprising at least one of the following: charging plug locked, charging station error, charging plan, availability of a charging station, availability of the electrical energy of the electrical

Energy storage, vehicle not safe against rolling (e.g. parking brake released, no gear engaged, automatic transmission not parking position, etc.). It is thus possible to determine a message in advance to the user's mobile device before, for example, a charging process fails and the user has already moved away from the vehicle or if, for example, the vehicle has to be charged, because otherwise z. B. due to changed

Environmental conditions (colder temperature, sudden weather, snowfall, darkness, etc.) the electrical energy is no longer sufficient to get to a charging station, drive home, etc.

The charging preconditions are evaluated in some exemplary embodiments when the charging plug is connected and when the user recognizes that the immediate vicinity has been left, but in others even when the vehicle is switched off or stopped, leaving the vehicle, etc.

If it turns out, for example, that at least one of the charging conditions is not met, the user can be informed of this via the transmitted message.

The message is transmitted, for example, when leaving the vehicle interior. B. can be determined by evaluating a door sensor system (opening / closing the door).

It can also be determined, as discussed, whether the user has left the vehicle's vicinity, has inserted the charging plug, and has communicated his charging request. Is z. B. recognized that the user has not noticed that a charging condition is not met or that there is an error in the system, despite the plug being inserted and the desire to charge, a corresponding message is sent to the mobile device.

This could also be: Vehicle not secure against rolling, charging plug not locked (none

Current flow allowed), No communication to the charging current controller of the charging station possible - error of the charging station, error in a HW / SW component of the charging current controller

Charging station or vehicle, forgot authentication (e.g. on the charging station), etc. In some exemplary embodiments, determining the location of the vehicle comprises determining an interesting location (POI, point of interest), as already indicated above. The interesting place can be a place where the user typically stays, such as his home (home address), workplace, shopping center, doctor, supermarket, but also

Charging station, train station, airfield, attraction, office, etc.

Depending on which interesting location is near the location of the vehicle, there can be different reactions. For example, it can be assumed that the user has a certain time, e.g. B. spends eight hours at work. This makes it possible to determine whether, for example, the remaining energy in the electrical system after eight hours

Energy storage is sufficient for a drive home (especially when it gets colder, etc.). Or it is determined that the location of the vehicle is in a structurally weak area (e.g. forest, far from a town), etc., so that it can be determined, for example, that with a certain waiting time, temperature change, etc the state of charge becomes critical and therefore the user is informed accordingly before he has left the vehicle and can no longer be reached, for example, via near field communication. This is also advantageous if there is no coverage by a mobile radio network or this is not available due to overload or a fault or the mobile radio network is currently not available.

In some embodiments, based on the position of the user and the location, it is determined whether the user intends to go to the interesting location, e.g. B. at home, to work, to the doctor, to go shopping, to the charging station, etc. This enables a behavior or intention of the user to be determined and the message to be transmitted to the user accordingly, as also explained above.

In some embodiments, the method includes determining whether a

Cellular network is available at the determined location. As indicated above, the failure of the mobile radio network can be critical since communication with the mobile terminal is then no longer possible. Accordingly, it can be provided that the message is transmitted based on the determined availability of the mobile radio network and, for example, another communication channel is used in the event of a failure of the mobile radio network or a lack of availability / coverage.

In some embodiments, the message is sent over a wireless

Near field communication transmitted to the mobile device, for example Bluetooth, wireless Network (WiFi), or another radio connection. This is helpful, even if, for example, a mobile radio network, as discussed, is not available, since the user can be reached via the mobile terminal.

Accordingly, it can be provided that the message is transmitted to the mobile terminal as long as the mobile terminal is in the area of near field communication. This ensures that the message is transmitted securely to the mobile device (especially if, for example, a mobile network is not available).

In some exemplary embodiments, the message is transmitted to the mobile terminal device as a push message, so that, for example, this is shown immediately on receipt on a display of the mobile terminal device, or at least it is indicated that a message has been received, as is known in principle in the prior art is.

Some exemplary embodiments relate to a controller for a vehicle with at least one electrical energy store, as described here, the controller being set up to carry out the method described here. The controller can have one or more (micro) processors, logic circuits, (volatile) main memory,

Read-only memory is stored in the program code for executing the method, for example, an interface that is designed, for example, for wireless communication with the mobile terminal (for example mobile radio, Bluetooth, wireless network (WiFi), etc.)

Communication with one or more sensors or antennas, with the aid of which, for example, the position of the user is determined, as described here, etc.

Some exemplary embodiments relate to a vehicle with at least one electrical energy store, as described here, and a controller, as described here.

Exemplary embodiments of the invention will now be described by way of example and with reference to the accompanying drawing, in which:

Fig. 1 shows schematically an embodiment of an electric vehicle with several areas for determining the position of a user and two near-field communication areas

illustrated;

2 shows a block diagram of an embodiment of a controller; and 3 shows a flow diagram of an exemplary embodiment of a method.

An embodiment of an electric vehicle 1 is illustrated in FIG. 1. The vehicle 1 has a plurality of areas 2a to 2e in which it can recognize the presence of a radio transmitter 3 which a user 4 carries with him.

The areas 2a to 2e are used to determine the position of the user 4, including the distance to the vehicle 1 and the direction in which he is moving, and each cover a distance of approximately 1.5 m, without the present invention restrict.

An area 2a is provided in the area of the front door on the driver's side, an area 2b in the area of the rear door on the driver's side, an area 2c in the trunk area, an area 2d in the area of a charging socket of vehicle 1 and in area 2e which covers the passenger's side.

In addition, two near-field communication areas 5a and 5b are provided, which in this exemplary embodiment provide Bluetooth communication, the

Near-field communication area 5a extends from the front part of vehicle 1 and near-field communication area 5b extends in the rear part of vehicle 1. The

Near field communication areas 5a and 5b have a range of approximately 10 m without restricting the present invention in this regard.

The user 4 also has a mobile terminal with him, which in the present

Embodiment is designed as a smartphone 6 and is set up to communicate via Bluetooth.

In addition, a charging station 7 is shown in FIG. 1, which is recognized, for example, as an interesting location and at which the user can charge the electric vehicle 1.

FIG. 2 illustrates a controller 10 of the vehicle 1, which has a processor 11, a memory 12 (exemplary working memory and read-only memory) and an interface 13 which is set up to receive radio signals from the radio transmitter 3 and to communicate via mobile radio and wirelessly via Bluetooth.

In addition, the controller 10 is connected to an electrical energy store 14 (eg lithium-ion battery). For communication with the radio transmitter 3, an associated antenna 15a to 15e is provided for each of the areas 2a to 2e, which can receive the radio signals emitted by the radio transmitter 3, so that the controller 10 due to the different signal strengths of the radio signals emitted by the antennas 15a to 15e can be received, the position of the radio transmitter 3 and thus of the user 4 who is wearing it can be determined, the position being the distance to the vehicle (eg also in which of the areas 2a to 2e the user 4 is with the radio transmitter 3) and also includes the direction of movement.

There is also at least one first antenna 16 for communicating with one

Mobile radio network is provided and at least one second antenna 17 for Bluetooth communication with the smartphone 6 (or, for example, one antenna for each

Near field communication area 5a and one for the near field communication area 5b).

Here, the first and the second antenna 16, 17 can also be a single antenna with two functions.

The controller 10 also has a navigation unit 18 with an antenna 19 for receiving satellite navigation signals (GPS, Galileo, etc.).

An exemplary embodiment of a method 20 is described below on the basis of a flow chart shown in FIG. 3, the method 20 typically being carried out by the controller 10 of FIG. 2.

After the start, the method 20 determines a location of the vehicle 1 at 21. For this purpose, it receives satellite navigation signals via the antenna 19 and the navigation unit 18 of the controller 10 determines a current location of the vehicle 1 based thereon.

In addition, the controller 10 determines places of interest in the vicinity of the vehicle 1, such as. B. the charging station 7, which is located near the vehicle 1. As stated above, other interesting places can also be determined, such as at home (home address), workplace, shopping facilities (supermarket, drugstore, pharmacy), restaurant, etc.

At 22, the method 20 determines a charging condition of the electrical energy store 14 (FIG. 1). For this purpose, the controller 10, for example, determines a current state of charge of the electrical energy store 14 and evaluates relevant data and for a high-voltage (HV) charging

Charging preconditions, such as a charging plan, charging request,

Support for low-voltage network charging, air conditioning, battery conditioning, etc. In addition, it is evaluated, for example, whether the charging preconditions are fulfilled when a charging request is present (e.g. while user 4 is moving away from vehicle 1) or whether charging would be required but was not started by user 4.

At 23, the method 20 determines a position of the user 4, as stated above, by evaluating the radio signals of the radio transmitter 3 accordingly, the position of the user 4 comprising the distance between the user 4 and the vehicle 1 and the direction of movement of the user 4.

At 24, method 20 determines whether a cellular network is available at the location of vehicle 1.

At 25, the method 20 determines whether a message should be transmitted to the user 4, in what way and what content this message should have.

At 26, the method 20 then transmits the message to the user 4 depending on the determination result of 25, that is to say depending on the determined location, the determined charging condition and the determined position (and possibly depending on whether a mobile radio network is available) .

Steps 25 and / or 26 contain a series of evaluations in which different scenarios are checked.

In some of these scenarios, the safety of the user is in the foreground, for example by giving the ability to drive the vehicle 1 a special priority and / or by giving the accessibility of the user 4 a special priority.

For example, it can have a high priority that the state of charge of the electrical energy store 14 is sufficient in any case to drive home, drive to work or drive to the next charging facility.

In addition, it can have a high priority to be able to notify user 4 in any case, in particular if it is determined at 25 that no communication via a mobile radio network is possible at the current location. Therefore, for example, the user 4 can be notified immediately about the near field communication if the user 4 exceeds a certain distance threshold value, for example that the charging at the charging station did not work or the state of charge is not sufficient to stay longer at the current location, for example because due to the low temperature, a faster drop in the state of charge is to be expected.

Or the vehicle is near the home address, it is evening and user 4 has connected a charging plug to the charging socket of vehicle 1, but has not locked it or forgotten to authenticate himself, start charging, etc. The charging status of the electrical storage 14 is so low, however, that it is no longer sufficient to get to work the next day (or it is no longer sufficient for the return trip).

Then a message is transmitted to his smartphone 6, e.g. B. as follows:

"If you want to make your planned trip tomorrow, you still have to start a shop." And / or

"Your charging plug is inserted, but is not locked. Please check your charging plug. "

At 26, the messages are sent as push messages via short-range communication (Bluetooth) to the smartphone 6, so that neither a cellular network nor an Internet connection are required.

The sequence of steps 21 to 25 is not fixed and can vary as required. Steps 21 to 26 can also (partially) be carried out in parallel or iteratively. In addition, steps 25 and 26, for example, can be viewed as a step implemented by a complex algorithm.

The method 20 can also be in the form of a computer program that contains corresponding instructions that cause a computer to execute the method 20 when executed.

Three scenarios or examples are described below with reference to FIGS. 1, 2 and 3, in which the method 20 is used.

First embodiment: The user 4 comes from work to his apartment, which is on the third floor, and parks on the street (step 21 determining the location of the vehicle).

The method 20 determines that the user 4 wants to take a longer trip the next day and wants to get into the air-conditioned vehicle in the morning (for example on the basis of calendar entries and weather data), but for what the current SOC (state of charge,

State of charge) is not sufficient (step 22, determining the charging condition).

The user 4 puts the charging plug of the charging station 7 into the charging socket of the vehicle 1 and starts charging the battery 14.

The user then moves away from vehicle 1 in the direction of the apartment (step 23, determining the position of user 4).

Due to an unfulfilled charging precondition (charging plug cannot lock etc.) or because the charging station 7 detects an error / cannot generate current, etc., the method 20 determines that charging cannot start (step 22, determining the charging condition ).

In addition, the method 20 recognizes that a distance threshold value is exceeded by the user 4 and that he is likely to go to his apartment (step 23 (determining the position of the user) in connection with the location of the vehicle determined at 21).

After the method 20 has determined that the loading (precondition) condition is not met, it transmits a message to the user 4 via near-field communication if the threshold value is exceeded (step 25). H. to his smartphone 6 (step 26, sending the message): "The loading of your vehicle could not be started. Please check yours

Charging plug "and / or:

“If you want to drive tomorrow to the destination specified in the calendar, you still have to start a shop. Please insert the charging plug and start a charging process. "

Second embodiment:

The user 4 parks his vehicle 1 in the Brandenburg Forest (step 21, determining the location of the vehicle), there being no mobile network coverage (step 24, determining whether a mobile network is available). The user 4 leaves the near vehicle area (ie one of the areas 2a-2e), which the method 20 recognizes accordingly (step 23, determining the position of the user).

It is also recognized that due to changed environmental conditions (falling

Temperature), the available energy of the battery 14 has changed (step 22, determining the charging condition).

Therefore, when leaving the close-range vehicle (one of the regions 2a-e) by

Near field communication (i.e. without the internet being required), user 4 received a message in the form of a warning message on his smart device 6 (step 26, transmission of message together with step 25) that he must note:

“The temperature at your current location has changed, which unfortunately affects your vehicle battery.

a) If you are air-conditioning on your return trip and want to go straight back to your place of residence and want to shop there, please only stay 2 hours and then drive straight to your place of residence.

b) If you want to use the next loading location in 'XY', you can stay at your current location for 2:38 h. "

Without the envisaged short-range communication and the sending of messages when the threshold value is exceeded, the user in this example might be due to the

Battery conditioning is faced with the situation that after its return the remaining electrical energy is not sufficient for a return trip or possibly not even to reach the next charging option.

In particular, if no (mobile) network is available or a network failure is imminent, the user 4 is to be informed last when leaving the near area of the vehicle 1 (areas 2a-e in FIG. 1) and before leaving the near field communication area (15a or 15b ) possibly a last "emergency anchor" if data relevant for loading can change (such as the temperature in the example).

Third embodiment:

The user 4 wants to go shopping or have a coffee and parks his vehicle 1 at the charging station 7 and starts charging the battery 14. The method 20 determines that the requested minimum SOC cannot be reached in the charging time, but a nearby charging station can provide more power (step 21, determining the location and determining the nearby charging station and that the user 4 wants to go shopping ( because a supermarket is nearby) and 22, determining the loading condition).

However, it may also be that the user 4 is in a hurry and has forgotten his authentication at the charging station 7 or this is unsuccessful, etc., which the user 4 does not notice.

Using the position determination of the user (step 23), a distance from the vehicle and a direction of movement away from the vehicle 1 are determined, and it is determined that the user 4 is likely to go shopping or into his “favorite coffee” (including the interesting ones) Places, determination in step 21, where supermarket or "favorite coffee" is an interesting place.).

If the threshold is exceeded, i. H. If the user 4 leaves the close-up areas 2a-e, the method 20 transmits a message to the smartphone 6 of the user 4 that a corresponding action still has to be carried out (e.g. go to another charging station, forget authentication, etc., step) 26, delivery of the message).

As a result, the user 4 is not only informed while sitting in the supermarket or in a coffee with friends, but rather in the vicinity of his vehicle 1.

Other scenarios or examples include, for example, the following alone or in (any) combination:

A charging plan and / or calendar of a user is evaluated, an expected performance of the charging station over time, charging conditions (as mentioned), times (start of work, end of work, rest at night, duration of shopping, etc.), etc.

Furthermore, periods can be taken into account in which the user is typically at certain POIs (interesting places), which has an impact on aspects relevant to charging (e.g. users like to go mountain hiking on Sundays, in weather data

announced drop in temperature, the state of charge of the battery after the end of the hike is no longer sufficient for the return trip or for the trip to the nearest one

Charging). As mentioned, the communication, ie the transmission of the message, can also take place independently of a mobile network and can take place in a (near field communication) area around the vehicle, where on-board communication with the user's mobile terminal is possible.

In the messages, the reasons and / or remedial measures that prevent loading can optionally be communicated.
