Description

Shaded parking assistance method, associated electronic device and motor vehicle.

The invention relates to the parking of motor vehicles.

There is a need to facilitate the parking of motor vehicles, particularly when the ambient temperature and/or sunshine is high.

• Détection (automatique) d’un besoin de stationnement ombragé,
• Obtention d’une heure de début,
• Réception d’une information de fin de stationnement du véhicule,
• Détermination d’une heure de fin de stationnement à partir de l’information de fin de stationnement,
• Réception d’une localisation géographique (actuelle ou, autrement dit, instantanée) du véhicule (100),
• Détermination d’une au moins position du soleil, à la localisation (autrement dit : apparente ou vue depuis la localisation) entre l’heure de début et l’heure de fin de stationnement,
• Détermination d’au moins une zone, (sur un sol) autour de la localisation, ombragée (i.e. ; non ensoleillée) entre l’heure de début et l’heure de fin de stationnement, à partir d’une carte géographique en trois dimensions (d’un périmètre autour de la position) et à partir de ladite au moins une position du soleil,
• (Emission d’une) Commande de la restitution d’un message (par exemple, à l’intérieur de l’habitacle du véhicule) à partir de ladite au moins une zone.

For this purpose, the invention relates to a parking assistance method, implemented in a motor vehicle, by an electronic device, characterized in that it comprises the following steps:

• (Automatic) detection of a need for shaded parking,
• Getting a start time,
• Receiving information that the vehicle has been parked,
• Determining a parking end time from the parking end information,
• Receiving a geographic location (current or, in other words, instantaneous) of the vehicle (100),
• Determination of at least one position of the sun, at the location (in other words: apparent or seen from the location) between the start time and the end time of parking,
• Determination of at least one area, (on the ground) around the location, shaded (i.e.; not sunny) between the start time and the end time of parking, from a three-dimensional geographic map (of a perimeter around the position) and from said at least one position of the sun,
• (Issuance of a) Command for the restitution of a message (for example, inside the passenger compartment of the vehicle) from said at least one zone.

By means of the invention, the user can choose where to park, depending on the anticipated departure time (i.e.: parking end time) and the vehicle's surroundings (e.g., buildings), so that the interior of the vehicle is as cool as possible at the departure time.

The vehicle location can be received from a vehicle satellite geographic location module.

The geographic location may include latitude, longitude, and possibly altitude (or elevation) above mean sea level (alternatively, it is a postal address).

The end of parking information can be, for example, a parking duration (the end of parking time is for example the sum of the start time and the parking duration) or the end of parking time.

• Une heure courante (autrement dit : instantanée et/ou locale),

The parking start information is for example:

• A current time (in other words: instantaneous and/or local),

The parking end time minus a predetermined time, for example relevant to a vehicle interior temperature at the parking end time.

According to one embodiment, the end of parking information is received from a human-machine interface of the vehicle, for example from a touch screen or a voice interface, located for example inside the vehicle.

Alternatively, the end of parking information is obtained from data in an electronic diary stored in the vehicle or received from another device such as a mobile phone connected to the vehicle.

The calendar may include, for example, a planned departure time which is then the end of parking information.

During the step of determining at least one position of the sun, said at least one position of the sun can be calculated from the location in a manner known to those skilled in the art.

Of course, the parking end time and the start time can each include a date necessary for such a calculation.

Alternatively, said at least one sun position may be received from a communication module of the vehicle, for example a communication module with a mobile telephone network, for example from a remote server.

Said at least one position of the sun may comprise a plurality of positions calculated at several times between the start time and the end time of parking. It is thus possible to determine the duration of shading of said at least one zone between the start time and the end time of parking, from the plurality of positions (and this may constitute a step of the method according to the invention).

For example, said at least one zone consists of surfaces shaded beyond a second duration threshold.

The message may also include (information on) the duration of shading during which the area is shaded or sunny.

According to one embodiment, the message restitution command controls the display of an image on a screen of the vehicle (inside the vehicle, preferably inside the passenger compartment of the vehicle).

The message may include information about the area.

The method according to the invention can thus comprise a step of displaying the image.

The image comprises, for example, (a representation of) said at least one area.

For example, (the representation of) said at least one area may be colored based on a shading duration in the area.

For example, the said image includes a map (around the location).

Alternatively, the playback command may command the playback of an audio message.

• Réception d’une mesure physique d’un environnement extérieur du véhicule (i.e. : de l’extérieur du véhicule) (depuis un capteur du véhicule),

le besoin de stationnement ombragé étant détecté à condition que (ou bien : si) la mesure physique soit supérieure (en variante : inférieure) à un premier seuil.According to one embodiment, the method according to the invention further comprises the following step:

• Receiving a physical measurement of an environment outside the vehicle (i.e.: from outside the vehicle) (from a vehicle sensor),

the need for shaded parking being detected provided that (or: if) the physical measurement is greater than (alternatively: less than) a first threshold.

For example, the physical measurement is an exterior temperature of the vehicle.

In this case, the first threshold can be between 20 degrees Celsius and 45 degrees Celsius.

• Réception d’une information de vitesse instantanée de circulation du véhicule (depuis un indicateur de vitesse du véhicule),

Le besoin de stationnement ombragé étant détecté à condition que (ou bien : si) la vitesse soit inférieure à un troisième seuil ou que le véhicule soit arrêté. Par exemple, le troisième seuil peut être inférieur à 20 kilomètres par heure et supérieur à 0 kilomètres par heure.According to one embodiment, the method according to the invention further comprises the following step:

• Receiving information on the instantaneous speed of the vehicle (from a vehicle speed indicator),

The need for shaded parking being detected provided that (or: if) the speed is below a third threshold or the vehicle is stopped. For example, the third threshold may be below 20 kilometers per hour and above 0 kilometers per hour.

Alternatively, the need for shaded parking is detected provided that it is (or: if it is) determined that the vehicle is at the end of a route along which the vehicle is guided by an electronic guidance module.

In general, the need for shaded parking can be detected independently of any (i.e.: without) stimuli (or message or information) received from a human-machine interface of the vehicle, i.e. independently of (i.e.: without) any input from a user. In other words, the need for shaded parking can be detected automatically.

Alternatively, the need for shaded parking may be detected upon receipt of user input by a human-machine interface of the vehicle.

• A la réception d’une prévision météorologique (par exemple à l’heure de fin) prévoyant des conditions météorologiques prédéfinies (par exemple des températures atmosphériques supérieures à un quatrième seuil), et/ou
• A ce que l’heure de fin ou l’heure de début soit dans une plage prédéfinie (par exemple durant les heures d’ensoleillement fortes).

The need for shaded parking can also be conditioned:

• Upon receipt of a weather forecast (e.g. at the end time) predicting predefined weather conditions (e.g. atmospheric temperatures above a fourth threshold), and/or
• That the end time or start time is within a predefined range (e.g. during peak sunlight hours).

In the absence of detection of a need for shaded parking, the other steps of the above process are not implemented. In particular, the restitution command is conditional on the detection of a need for parking.

The invention also relates to a computer program comprising instructions, executable by a microprocessor or a microcontroller or a computer, for implementing the steps of the method according to the invention, when it is executed by the microprocessor or the microcontroller or the computer.

The method according to the invention can be implemented by an electronic device.

The map may be stored in the memory of the electronic device. Alternatively, it may be in a remote server.

The invention also relates to an electronic device configured to implement the steps of the method according to the invention, and a vehicle comprising the device. The electronic device may be a microcontroller or a microprocessor, for example.

The characteristics and advantages of the electronic device, the motor vehicle, or the computer program are identical to those of the method, which is why they are not repeated here.

It is understood that the electronic device, motor vehicle, or other element is “configured to” (or “capable of”) performing or implementing a step or operation, by the fact that the element includes means for (in other words “is shaped to” or “is adapted to”) performing the step or operation. These are preferably electronic means, for example a computer program, data in memory, specialized electronic circuits, wired or wireless connections, or a microprocessor of a microcontroller.

When a step or operation is performed (i.e. implemented) by such an element, this generally implies that the element includes means for (i.e. “is shaped for” or “is adapted for” or “is configured for”) performing the step or operation. Examples of such means include electronic means, such as a computer program, data in memory, specialized electronic circuits, wired or wireless connections, a microprocessor or a microcontroller.

Detailed description of an exemplary embodiment of the invention.

Referring to FIGS. 1 to 3, in step S00, the motor vehicle 100 slows down upon arrival at a destination of a journey to a speed of 10 kilometers per hour.

In step S10, the electronic device 110 (which may have the architecture of a microprocessor or a microcontroller) receives information according to which the instantaneous speed of circulation of the vehicle is 8 kilometers per hour from a speed indicator of the vehicle 100.

In step S20, the electronic device 110 receives, from the outside temperature sensor 140, information that the outside temperature 200 of the vehicle 100 is 30 degrees Celsius.

At step S30, the electronic device determines that the instantaneous speed is less than 10 kilometers per hour, and that the outside temperature is greater than 30 degrees Celsius, and therefore, automatically, a need for shaded parking.

If no need for shaded parking is detected, the other steps above are not implemented.

In step S40, the electronic device 100 receives, from the voice interface 160, the information that the end of parking is scheduled for 4 p.m. on July 31, 2023, from words spoken by the driver.

In step S50, the electronic device 100 determines a start time 1 hour before the end of parking, i.e. equal to 3 p.m. on July 31, 2023.

In step S60, the electronic device 100 receives the geographic location of the vehicle 100 from a satellite geographic location module 120 (usually called “GPS”) of the vehicle 100.

Geographic location can include latitude and longitude.

In step S70, the electronic device 100 calculates, in a known manner, a position of the sun, at the geographic location, every 10 minutes, between 3 p.m. and 4 p.m.

In step S80, the electronic device 100 calculates (in a manner known to those skilled in the art) a duration of shading around the location, between 3 p.m. and 4 p.m., from the plurality of positions of the sun calculated in step S70, and from a map of a three-dimensional geographic map 111 stored in the electronic device 100. Thus, the height of the buildings is taken into account for example.

In step S90, the electronic device 100 controls the display of an image 300 by the screen 150 located inside the passenger compartment of the vehicle 100.

Image 300 includes a representation 100' of vehicle 100, a map around the location of vehicle 100 including lanes 320 and 340 and buildings 320 and 310. The image also includes representations 311, 312, 313, 314, 315, 331, 332 and 333 of shaded areas between 3 p.m. and 4 p.m. around the location. Representations 312, 314 and 332 have a first color to indicate that the corresponding areas are shaded all the time between 3 p.m. and 4 p.m. Representations 311, 313, 315, 331 and 333 have a second color to indicate that the corresponding areas are shaded for more than 30 minutes and less than one hour between 3 p.m. and 4 p.m.
