Description

Method for managing technical data related to the use of functions of a motor vehicle

The present invention relates to a method for managing technical data for the use of the functions of a motor vehicle, a computer program product, a system for managing technical data for the use of the functions of a motor vehicle and a motor vehicle comprising such a system.

State of the art

Currently, a motor vehicle includes a multitude of functions ranging from driver assistance functions (cruise control, lane keeping assist, etc.) to comfort functions (air conditioning, sound system, etc.) and safety functions.

However, to date, it is very difficult to know how drivers use these different functions. Most often, surveys of drivers or equivalent methods are used.

This has the disadvantage of not allowing manufacturers to have precise and exhaustive feedback on the implemented functions and therefore to be able to optimize them.

This also has the disadvantage that the driver does not have reliable information on how he manages his vehicle and therefore, possibly, cannot optimize the different functions to his habits.

This also has the disadvantage of not being able to implement predictive maintenance programs based on the actual use of the different functions.

There is therefore a real need for a process and a system for managing technical data related to the use of the functions of a motor vehicle that resolves all or part of the aforementioned drawbacks.

The invention will be better understood upon reading the following description, given solely by way of example, and with reference to the figures in the appendix in which:

• FIG. 1 represents a top view of a vehicle comprising a technical data management system for the use of functions according to a given embodiment; and
• FIG. 2 represents a flowchart of a process for managing technical data for the use of functions according to an embodiment.

Methods of implementation

The embodiments presented below refer to a motor vehicle, a car. However, those skilled in the art understand that they are also applicable to other types of vehicles such as vans, trucks, etc.

The terms "front", "rear", "high", "low", "transverse" are understood in relation to the vehicle.

With reference to the FIG. 1 , a motor vehicle 1 includes a system 3 for managing technical data on the use of the functions of a motor vehicle comprising at least one sensor 5 adapted to collect technical information on the use of the functions of the vehicle, in particular the time, or date, of use and the duration of use.

System 3 includes a controller 7 connected to sensor 5.

Controller 7 can, for example, be integrated into the vehicle control system 1 as an advanced driver-assistance system (ADAS), which makes all driving decisions based on the environment and the programmed destination. The vehicle is then described as an autonomous vehicle. However, it can also be a centralized vehicle management system that may or may not include driver assistance features.

Data transfer between the different elements is preferably carried out via a CAN ( Controller Area Network) type data bus.  » in English, i.e. “controller zone network”) or LIN (for “Local Interconnect Network” in English, or “Local Interconnect Network” in French).

The controller 7 is connected to a database 9 to store the data collected by the sensors 5.

It is also connected to a screen 11 of a vehicle's human-machine interface, typically a screen on the vehicle's dashboard 1. Preferably, the screen 11 is a touchscreen allowing the driver to interact with the information displayed. This can also be done via controls available on the dashboard.

The operation of system 3 is as follows, FIG. 2 .

Each time a vehicle function is used, sensor 5 detects it, step 21, and collects in real time the timestamp and duration of use.

This data is transferred to controller 7, step 23, to be stored, step 25, in database 9.

Generally at the request of the driver, or, for maintenance purposes, at the request of the mechanic, the controller 7 makes a summary, step 27, of the use of the different functions and sends this to the screen 11 to be displayed, step 29.

Thus, the driver, or the mechanic, has an advantageously clear and precise view of the use of the different functions of the vehicle.

There FIG. 1 This illustrates a system according to certain embodiments. The breakdown presented is for pedagogical purposes, highlighting the different functions. However, it is understood that each block can be implemented using various means or combinations thereof, such as hardware components, software, one or more computers, and/or electronic circuits. Each component can include at least one computer or a control unit. At least one memory can be included in each component. The memory can contain computer program instructions or software code.

Calculators can be implemented using any type of data processing device, such as a central processing unit, a signal processing unit, a specific application integrated circuit, a programmable gate network, etc. Calculators can be implemented as a single controller, or as a plurality of controllers or calculators.

The different modules are connected to each other by data links adapted to the environment. These can be wired or wireless.

For software, the implementation can include modules or units distributed as procedures, functions, etc. Memory can be any type of storage circuit. It can be part of the processor circuitry, or separate and connected via electrical data links. This can include non-volatile memory, hard drives, RAM, flash memory, etc.

Furthermore, the program instructions stored in memory and processed by computers can be any type of program code, for example, a compiled or interpreted program written in a suitable programming language.

The computer program instructions stored in memory are such that, when executed by the computer, the latter carries out one or more of the steps of the processes described above.

The invention has been illustrated and described in detail in the drawings and the preceding description. This description should be considered illustrative and given by way of example, and not as limiting the invention to this single description. Numerous embodiments are possible.

In one variant, the use of the different functions is displayed as a frequency of use measured in terms of the number of times the function is activated per unit of time.

In a second variant, sensor 5 collects, for each function, the frequency and duration of use of each option, command, or setting. This allows for a detailed summary of function usage and potentially enables the function to be personalized to the driver's needs and habits.

In a third variant, information is presented in the form of a presentation of the most frequently used functions. For example, as a list in descending order of function usage.

Also, in a fourth variant, the screen of functions available to be activated by the driver is sorted so that the most used functions are presented first.
