Description

Title of the invention: Method for parameterizing an on-board vehicle system using a measurement unit Technical field

[0001] The present disclosure generally relates to a method, software and / or an on-board system of a vehicle, as well as a corresponding vehicle. State of the art

[0002] Methods and systems for configuring a vehicle dashboard display are known in the prior art, for example according to document US2013 / 0293364.

[0003] Statement of Disclosure

[0004] A first aspect of the disclosure relates to a method for parameterizing or adjusting an on-board vehicle system, the on-board system comprising a processor and software, the method comprising the following steps: - reception, by the processor, of a unit of measurement to be used by the embedded system, - application, by the processor and depending on the choice of the unit of measurement, of a setting to be used by the on-board system.

[0005] Thus, it is possible, depending on the choice of the unit of measurement, to configure the on-board system according to a country in which a vehicle is or will be located. The setting is a setting that configures at least one function of the on-board software. This setting can make it possible to comply with local legislation without additional hardware in the vehicle and without complicating a vehicle production line. For example, the unit of measurement can be a set of units of measurement. The unit of measurement can be selected in a menu or sent through a machine code representing it.

[0006] Conversely, a method according to the state of the art and based on a location obtained by a positioning system requires additional hardware within the vehicle such as a satellite location system, as well as mapping data. The present method therefore makes it possible to manage the diversity of local legalizations for any type of vehicle, including low-end or utility vehicles, in an inexpensive manner.

[0007] Advantageously, the unit of measurement is a unit of volume, a unit of temperature, or a unit of fuel consumption. For example, this unit may be the gallon, the degree Fahrenheit, or the mile per gallon, respectively. Since these units are primarily or solely used in the United States of America, a safety setting that complies with the legislation of the United States of America may be applied when at least one of these units is received by the processor.

[0008] Advantageously, the method comprises a step of downloading or transferring, by the processor and to a memory of the embedded system, a software component and / or a data component depending on the setting. Alternatively or in combination, the method comprises a step of selecting, by the processor, a data component or a software component stored in the memory of the embedded system.

[0009] For example, the data component may include a set of graphical, textual, or interface elements. The software component may include a function required or prohibited by local law.

[0010] Advantageously, the application of the adjustment comprises the activation, periodic activation or deactivation of a function of the on-board system. This function can be carried out by a software component downloaded or stored in the memory of the on-board system.

[0011] Advantageously, the application of the setting comprises the activation, periodic activation or deactivation of the function of the on-board system according to a driving situation of the vehicle. The driving situation may be a movement of the vehicle or a speed. In addition, a general state of the vehicle may be taken into account, for example of a peripheral, such as the opening of doors or windows of the vehicle or the use of a function of the on-board system.

[0012] Advantageously, the function of the on-board system comprises the production of a warning message and / or a disclaimer, preferably by display on a screen of the on-board system. For example, this may be a one-time production or a periodic production, for example every 25 days.

[0013] Advantageously, the function of the software is an input function, for example a virtual keyboard on a touch screen or a physical keyboard or button in the vehicle. In addition, the function may be a function of pairing a mobile device or the vehicle's on-board system.

[0014] Advantageously, the method comprises a step of acquiring, by an acquisition interface, the measurement unit, in which the acquisition interface is preferably a wired interface, a wireless interface, a keyboard or a touch screen of the on-board system. For example, this acquisition step is carried out in the factory, by an importer or by a distributor of the vehicle. Preferably, the adjustment of the unit is not accessible to a user of the vehicle: the acquisition interface may not be accessible or have a limited function for an end user of the vehicle.

[0015] A second aspect of the present disclosure relates to software, i.e. a computer program product, intended for an on-board vehicle system, comprising steps or instructions implementing the steps of the first aspect.

[0016] A third aspect of the disclosure relates to an on-board computer system for a vehicle comprising software and a processor, configured to implement the method according to the first aspect of the disclosure or comprising the software according to the second aspect of the disclosure.

[0017] A fourth aspect of the present disclosure relates to a vehicle comprising an on-board system according to the third aspect, or implementing the method according to the first aspect or the software according to the second aspect of the disclosure. Description of the figures

[0018] Other characteristics and advantages of the present disclosure will appear more clearly on reading the following detailed description of an embodiment given by way of non-limiting example and illustrated by the appended drawings, in which:

[0019] [Fig-1] represents an on-board system of a vehicle.

[0020] [Fig.2] shows a method of adjusting the embedded system according to one aspect of the disclosure.

[0021] [Fig.3] represents a view of a function of the embedded system of [Fig.l] as presented to a user according to a unit of measurement.

[0022] [Fig.4] represents a view of a function of the embedded system of [Fig.l] as presented to a user according to another unit of measurement.

[0023] Detailed description of embodiment(s)

[0024] [Fig.l] represents a general diagram of an on-board system 10 for a vehicle. The on-board system 10 comprises at least one processor 11 and preferably at least one memory 12 and a wired interface 13 intended to communicate with an on-board computer system, for example a diagnostic socket. In addition, the on-board system 10 may comprise a network interface 14 or serial interface (CAN data bus) allowing communication with other elements of the vehicle and / or a wireless interface 15 such as Bluetooth, NFC or Wi-Fi.

[0025] The embedded system 10 may comprise or be connected to a display 20, which may also comprise an input interface (touch screen). In addition, other input interfaces may be provided such as one or more buttons, touchpad, as well as one or more microphones enabling voice recognition.

[0026] [Fig.2] represents a method according to the present disclosure. In a step (E0) optionally, a unit of measurement may be acquired. For example, a machine code corresponding to the unit of measurement is transmitted by an off-board system via the wired interface 13 or the wireless interface 15 to the processor 11. Alternatively, a unit of measurement may be selected on the display 20. Preferably, the unit of measurement is not adjustable by the end user. For example, the wired interface 13 or the wireless interface 15 is not accessible or has limited functions for the end user. Thus, the user cannot change the unit of measurement or the applied setting.

[0027] In a first step (El), the unit of measurement is received by the processor 11. This unit of measurement is intended to be used by the on-board system and comprises, for example, a unit of volume, a unit of temperature and / or a unit of fuel consumption. For example, the unit of measurement may be chosen or selected from liters or gallons, degrees Celsius or degrees Fahrenheit and / or liters per 100 kilometers or miles per gallon.

[0028] Other units may be considered as a unit of length (miles or kilometers), a unit of pressure (PSI or bar), a unit of energy (BTU or Joule) or any other unit applicable to the vehicle's on-board system. Any unit specific to one or more geographical areas may thus be used. The unit of measurement preferably corresponds to a measurement carried out or achievable by an on-board computer of the vehicle.

[0029] In a second step E2, the unit of measurement is applied by the processor to the embedded system, in particular to the software. For example, the setting corresponding to the unit of measurement may be stored in the memory 12. For example, the setting is linked to a country or region of the world such as "USA", "Switzerland", "Europe" or "World". Alternatively or in combination, the selected unit of measurement may be stored in the memory 12 as the unit to be used by the embedded system 10 or as the unit for display on the screen or display 20.

[0030] Furthermore, an optional additional step may comprise receiving or downloading data components and / or software components related to the unit of measurement or the country or region of the world (E3-1). This download may be initiated by the processor and / or performed from an off-loaded or cloud-based database or storage space, for example through the wired interface 13 or the wireless interface 15.

[0031] An optional additional step may also comprise the selection or deletion in the memory 12 of one or more data components or software components (E3-2). The software or data components may be part of the embedded system 10, i.e. executed by the processor 11 and / or displayed on the display 20.

[0032] An optional additional step (E3-3) may comprise activating, periodically activating or deactivating functions of the on-board system, for example software components of the on-board system, such as a software component downloaded or stored in the memory. The function deactivation may be carried out according to a state of the vehicle, such as a driving state. One or two of these additional steps or all three optional steps may be carried out, as required.

[0033] These data or software components may comprise user display data to be displayed on the display 20 and / or functions of the software of the embedded system. Thus, the behavior of the software of the embedded system, in particular of the part of the software interacting with a user (Human-Machine Interface - HMI) can be modified according to the setting and adapted to local legislation.

[0034] The user display data may include a disclaimer or security message to be displayed only once, each time the vehicle or software component is started, or periodically, depending on the setting.

[0035] The software or functions of the on-board software may include the availability or unavailability of an input interface such as a touch keyboard on the display 20, for example when the vehicle is moving, the availability or unavailability of a function for pairing a mobile device with the on-board system 10 via the wireless interface 15, or the activation or deactivation of a production of a message, for example on the basis of user display data.

[0036] [Fig. 3] shows an example of a function of the on-board system, as displayed on the screen 20. In this use case, a user of a moving vehicle wishes to use a function requiring sustained attention, therefore not compatible with safe driving, for example an input interface such as a touch keyboard on the screen 20. In this case, a deterrent message 21 can be displayed on the screen 20, and this message can be accepted by an acceptance button 22, in which case the deterrent message disappears and the software returns to a previous display situation.

[0037] If a unit of measurement of the international system or used worldwide has been received, an override button 23 may be displayed, thereby allowing a passenger to access the input interface. For example, this type of override button 23 is permitted in most countries of the world.

[0038] [Fig. 3] shows an example of a function of the on-board system, as displayed on the screen 20 in the case of a unit of measurement linked to the United States of America having been selected, for example the gallon. Only the acceptance button 22 is available and the bypass button 23 is not displayed. The input interface is therefore not accessible when the vehicle is moving, according to the legislation of this country. Alternatively, the acceptance button 22 is not accessible and only the deterrent message 21 is displayed, for example for a given time before disappearing, thus allowing the software to return to a previous display situation without intervention from the driver.

[0039] Another feature or software related to the “United States of America” setting may be the periodic display of a disclaimer, for example every 25 days.

[0040] Other software or functions of the on-board system may be activated or deactivated depending on the setting, for example an autonomous driving function, a video and / or audio monitoring function of the vehicle or its environment, a data collection function, a location function, etc.

[0041] The setting may be conditioned on another data or parameter, in addition to the unit of measurement, for example a language setting, a vehicle type, etc. Industrial application

[0042] The present method is capable of industrial application in any type of vehicle, for example a personal, utility, collective, military or specialized vehicle, with two, three, four, six or more wheels.

[0043] It will be understood that various modifications and / or improvements obvious to those skilled in the art may be made to the various embodiments described in the present disclosure without departing from the scope of the claims. In particular, it may be noted that the data components and software components are not limited to the examples provided above.

[0044] Furthermore, the embedded system is not limited and may include multiple displays, multiple processors, multiple memories, and voice interfaces, as known to those skilled in the art. A satellite tracking system may be included, even if not required by the present method.

[0045] The embedded system may include multiple computer modules operating in an interconnected manner. For example, a first module may receive the measurement unit and a second module may apply the adjustment.

[0046] The display 20 may further comprise a head-up device, a passenger screen and / or a mobile device connected or paired or connected to the on-board system 10.
