Detailed Description

The drawings and the following description relate to exemplary embodiments, which serve to provide a better understanding of the invention, but also to contribute to its definition, where appropriate.

The invention is applicable to different vehicles in a line or fleet of vehicles.

The vehicle comprises a seat adjustment device which enables an at least partially automatic adjustment of the seat.

An adult series of vehicles is understood to mean vehicles of different models from one car manufacturer. A fleet of vehicles is understood to mean, for example, vehicles of multiple lines of an operator (e.g., a rental company).

The invention proposes to allow the determination of the seat adjustment in the new vehicle based on the seat adjustment in the first vehicle.

This determination can be made, for example, from a correlation table between vehicles giving turn-down ratios, in the following examples, or taking into account the size data of the passenger compartment of the first vehicle for the identified user, the seat adjustment of this first vehicle for the user, and the size data of the passenger compartment for the new vehicle quantity, or using an estimated form of the user.

In a first example, the dimensional data considered are the size of the seat, the seat/pedal distance, the height of the seat relative to the vehicle floor, the seat/steering wheel distance, and more generally the dimensions used to define the seat size and place it in the passenger compartment.

Fig. 1 schematically shows an embodiment of the invention in which data is transmitted between vehicles via a communication network and in which the calculations necessary for the automatic seat adjustment of the invention are carried out in a remote computer system.

Fig. 1 thus shows the driving position of a vehicle 1 suitable for implementing the invention, said vehicle comprising at least one computer 140 connected together for calculating the adjustment of at least one seat connected to the actuators and sensors 142, 144 of said seat.

Here, the vehicle comprises means 160 for identifying the users of said seats, to identify the users and to input or recall data of these users.

In this example, the vehicle includes a communication unit or module 120 for communicating with the remote computer network 2.

The identification device 160 may be of a known type, such as a badge reader, an input keyboard, a key receiver, such as a bluetooth receiver that receives data from a smart phone.

The communication module may be part of a passenger compartment computer, an entertainment module, or a module for managing passenger compartment functions, etc.

The seat adjustment module 140 or computer includes manual adjustment means 146, such as buttons for actuating an electric motor, and means for automatically adjusting the seat via the motor. The computer may also include a user's local memory and associated adjustments for known users for directly adjusting the seat.

The automatic adjustment means are adapted to make adjustments based on adjustment data received from the communication unit.

The communication unit comprises means 121 for transmitting and receiving data, for example in the form of a cellular telephone transmitter/receiver. By means of these transmission means, the seat adjustment data, the vehicle type identification data and the identification data of the user will be transmitted to or from a remote computer network, when the remote computer network itself is provided with communication means via a cellular telephone network.

In a known manner, the vehicle 1 comprises a steering wheel 110, pedals 112, a rear-view mirror 115, a dashboard 114, a floor 117 and a roof 113. The mentioned positions of the various driving accessories and devices constitute the passenger compartment size parameters specific to this vehicle.

The dimensional parameters of all vehicles of the system of the invention, for example the passenger compartment parameter P, are grouped in the database 220 of the remote computer system 2, for example consisting of the computer server of the vehicle manufacturer in the internet cloud.

The vehicle is configured to transmit its identification, seat adjustment parameters and the corresponding user identifier to the computer system 2 via the communication unit, said computer system 2 comprising for example a transmission/reception device 310 connected to a telephone network of the type 3G, 4G or 5G, for example.

The computer system comprises a calculation unit 200 accessing a database 220 which groups the size parameters of the passenger compartment of all vehicles or the ratio between the size data of the vehicles, so that the seat adjustment data can be recalculated for all vehicles, which allows retrieving vehicle related parameters, such as the position of the pedal 112 relative to the seat 100, the size of the seat, the position of the steering wheel etc., upon receiving the vehicle identifier.

The calculation unit further comprises a program equipped with a calculation algorithm adapted to calculate seat adjustment data of the second vehicle from the dimensional data of the first vehicle and any second vehicle of the system and from the identified seat adjustment parameters of the user. This applies to the third vehicle or any other vehicle associated with the system.

It should be noted that the user identifier may be encoded or anonymized for personal data security reasons.

According to fig. 2, to implement the invention, the user of a first vehicle of a first type, referred to as vehicle V1, obtains a unique identification number (Id) which is stored, for example, in the vehicle's passenger compartment computer in a first step 10.

The user may then adjust his or her seat manually by using the operator interface 146 for use on the seat motor, or may adjust his or her seat with an auxiliary adjustment based on the initial form parameters associated with the identifier. When satisfied with the seat adjustments obtained, the user accepts the adjustments.

In a second step 20, the seat adjustment considered, including the seat position and, where appropriate, additional adjustments for comfort elements (e.g. lumbar supports, headrest position or others), together with the vehicle identifier V1, are associated with the user identifier.

In a third step 30, the vehicle transmits the user identifier Id1, the type of adjustment R1 and the vehicle V1 to the remote computing system 2, which remote computing system 2 stores the adjustment data R1, the user identifier Id1 and the type of vehicle 1V 1 in the database 240.

Referring to FIG. 3, when the user uses a second vehicle V2 of a different type, the user enters his or her identifier associated with the type of vehicle V2 in step 50 and is transmitted by vehicle V2 to the computer system 60 in step 60. The computer system uses the adjustment data R1, the user identifier Id1, and the type of vehicle V1 extracted from the database 240 to perform step 70, in which step 70 adjustment data 80 for the seat of vehicle V2 is calculated based on the passenger compartment size data for vehicles V1 and V2 extracted from the database 220.

The database 240 comprising the user identifiers may be a database secured in a conventional manner linked to a server system adapted to communicate with the vehicle in, for example, an encrypted manner.

The system of the invention thus enables adjustment data customized for the user to be provided for each vehicle in a number of production lines from an automobile manufacturer, based on a database of passenger compartment sizes of vehicles from said production lines and on adjustment data of individual seats.

In summary, therefore, the system of the present invention provides customized adjustment data for an identified user for each vehicle connected to the system based on the dimensional data of vehicle V1, adjustment data of seat R1 of vehicle V1, a user identifier, and dimensional data of vehicles of a different production line of the manufacturer or manufacturers.

The automatic adjustment method of the present invention may include:

-a step 10 of assigning an identifier to the user,

for a first use of the first vehicle, a first step 20 of entering an identifier, adjusting the seat and storing seat adjustment data,

a step 30 of transmitting the seat adjustment data obtained by the adjustment and the user identifier to the conversion means 40,

-a step of converting seat adjustment data of the first vehicle into seat adjustment data of the second vehicle in a conversion means,

-a step of automatically adjusting the seat occupied by the user based on seat adjustment data of the second vehicle from the converting step.

In the case of a conversion taking into account the passenger compartment data of the vehicle, the conversion uses a calculation program with an algorithm taking into account the passenger compartment size data of the first vehicle V1 and the passenger compartment size data of the second vehicle V2. As mentioned above, the conversion means may also be based on a scale applied to the adjustment data as a function of the vehicle.

It should be noted that if the second vehicle is identical to the first vehicle, it is obviously not necessary to recalculate the adjustment amount, since the adjustment amount of the first vehicle applies.

In this case, unless all vehicles in the system are converted and the conversion is stored, the step of identifying the user identifier in the second vehicle is performed before the conversion step, and then, after the user and the vehicle are identified, only the data of the second vehicle is transmitted for the second vehicle.

For a system to perform the conversion in a central computer system remote from the vehicle, the step of transmitting the seat adjustment data of the second vehicle from the conversion device to the second vehicle and its seat adjustment device has to be performed. On the other hand, if the change over is made in the second vehicle, a transmission takes place inside the vehicle between the change over device associated with the vehicle and the seat adjustment device.

More precisely, different types of vehicles may be of different lines, series or versions, e.g. from car manufacturers, such as compact, car, SUV or utility. These vehicles, referenced in the manufacturer or operator's database 220, include an internal computer adapted to receive seat adjustment data and automatically adjust the seat based on such data.

The invention is particularly applicable to driver seats whereby passenger compartment data is best enriched, but may be applied to passenger seats.

In the embodiment of fig. 1, the conditioning data and the identifier are transmitted between the vehicle and a networked computer system over a radio network 300 for transmission/reception of digital data, and the calculating step is performed within the networked computer system.

The advantage of performing calculations based on a database is that the system is provided with significant flexibility as product lines or fleets develop and in case of development of calculation algorithms, for example, allows further addition of dimensional data.

The system also allows fine adjustment of the seat adjustment as the user of the system fine-tunes their adjustment or uses a different vehicle.

Furthermore, the system is adapted to anonymize the user data by replacing the user identification data with definition data of an equivalent human model, which may be suitably written in the user identification badge and transmitted in place of the user identifier.

The system is particularly suitable for vehicles comprising a local computer network for passenger compartment management, and said network comprises: at least one computer 140 connected together, means 160 for identifying the user of the seat, a communication unit 120 for communicating with a remote computer network, said computer 140 being used for calculating the adjustment of at least one seat connected to the actuators and sensors 142, 144 of the seat.

Each vehicle in the system is then configured to issue a request comprising the user identification and the type of the vehicle to the computing device of the computer network, which itself is configured to feedback to the requesting vehicle:

-or, for a known user, seat adjustment data is calculated for said user by said algorithm, the requesting vehicle computer being adapted to automatically adjust the seat occupied by the user based on seat adjustment data feedback;

or, for an unknown user, requesting transmission of the user's seat adjustment data, the vehicle making the request then becoming the first vehicle for which the user must make the first seat adjustment.

According to another embodiment, shown in fig. 4, the system of the invention is implemented directly in the vehicle, the seat adjustment calculation of the second vehicle being performed for example directly in the second and subsequent vehicles, which receive, by means of a device carried by the user: a user identifier, size data of a passenger compartment of the first vehicle, and seat adjustment data of the first vehicle.

In this case, the means for calculating the seat adjustment data are integrated into the module 150 of the vehicle, in which case the server can limit itself to transmitting the size data of the vehicle V1 to other vehicles if necessary, the other data being grouped, for example, in an external device carried by the user.

In this case, the vehicle also comprises a module 120' for exchanging data with an external device 122 carried by the user, in order to exchange size and seat adjustment data.

However, it should be noted that the computing device may be integrated into the seat adjustment computer, or may be a separate module, as the communication module 120' may be integrated or coupled to the identification device 160.

The seat adjustment calculations are performed for the seat of the second vehicle in a calculation module 150 of the second vehicle, which module may also be in a seat adjustment computer or in a device 120 'for data exchange with an external device 122 worn by the user, which may be an activity badge, the user's mobile phone or any other storage means.

The vehicle has its own passenger compartment size data and a calculation program providing a calculation algorithm for transforming calls in accordance with the size data of the original vehicle and the new vehicle transmitted by the external device without transmission to an external network, which eliminates the need to transmit user data between the vehicle and the network or to store user identifier data in the external data, for example.

In this simplified embodiment, where the user stores the seat adjustment data for his or her first vehicle in an external device, the function of the vehicle dimensions database may also be integrated into the external device. For example, the external device may be a smartphone that receives such data from a remote computer network through an application program, the external device serving as an interface between the vehicle and the remote computer network (e.g., a manufacturer network) for the seat adjustment data of the user.

In the embodiment involving fig. 5, for the calculation of seat adjustment data, the system may use estimated form parameters calculated from the dimensional data of the first vehicle and the seat adjustment data of the first vehicle. In this case, the estimated form would be stored in database 240' of FIG. 5 along with the user identifier.

In this embodiment, the calculation will comprise a first step of calculating the estimated form of the user by means of a first calculation program based on the first manual adjustment parameters from the first database 220 or integrated into the computer of the vehicle and the size parameters of the passenger compartment of the first vehicle.

In step 10 ', the user specifies his or her identifier Id1, and then makes an adjustment in step 20'. The vehicle then transmits the user identifier and adjustment data to the remote system 2 in step 30'.

Then, in step 40 ', the method will include calculating the user's estimated form by considering the dimensional data of vehicle V1 from database 220. At the end of the calculation, the pre-estimated modalities associated with the user identifier are stored in the second database 240'.

When the user uses a second vehicle V2 of a different type from the first vehicle, the second vehicle transmits the type of the vehicle V2 and the user identifier. After identifying the identifier and retrieving the user's estimated form from the second database 240 ' and the second vehicle's dimensional parameters from the first database 220, a second calculation step 70 ' calculates second seat adjustment parameters 80 ' for the second vehicle V2, calculated by a calculation program based on the user's estimated form and the second vehicle's dimensional parameters.

In the case of calculations made in a remote computer, the adjusted seat adjustments 80 'are transmitted to the second vehicle's seat computer to automatically adjust the second vehicle's seat in step 90', and the second calculation step and the transmission of adjusted seat adjustments will be repeated for any new vehicle.

Dimensional parameters useful for determining the estimated form include, for example, the position of the steering wheel 110, which together with the position of the seat enables estimation of the arm length, the position of the pedals 112 allowing estimation of the leg length, depending on the position of the seat, the positions of the ceiling 113 and the dashboard 114 and the size of the seat.

In this case, the database 240' that groups the user identifiers and their estimated modalities is a secure database external to the vehicle. It may further include additional statistics for refining the morphology estimate.

The inventive method may be repeated for any new vehicle in the inventive system. Where the algorithm uses an estimated form, the form may be further enriched when the user uses a new vehicle that includes additional types of adjustments not present in the previous vehicle.

The invention is not limited to the described example, which allows for improved comfort for the user without increasing the number of sensors in the passenger compartment by customizing the position of the seat on a plurality of different vehicles so that the user automatically obtains the appropriate seat adjustment when he or she uses different vehicles of the system of the invention.

Further, the vehicle may include a user's local memory and associated adjustments to allow for adjustment of the seat according to the user when the user is known.

For the car manufacturer, the invention makes it possible to provide its customers with a personalized comfort sensation in all its models.
