Description

System and method for securing a motor vehicle and motor vehicle comprising such a system

The present invention relates to a system and a method for securing a motor vehicle and to a motor vehicle comprising such a system.

State of the art

With the evolution of automotive practices, it has been noted that vehicle loans (outside of rental companies) are becoming more and more frequent.

This may correspond to one-off needs associated with services such as vehicle washing or repair, restaurant or performance hall valet service. It may also correspond to loans between individuals organized or not by sharing platforms.

The guarantee of successful completion of the loan then rests solely on the trust that the lender is prepared to place in the borrower.

There is therefore a real need for a system and a process which can strengthen the security of the loan beyond this trust.

Description of the invention

• une interface adaptée pour saisir un code d’accès et au moins un paramètre parmi une durée d’utilisation, une distance d’utilisation et une zone d’utilisation ; connectée à

Methods of implementation

The embodiments presented below refer to a motor vehicle, a car. However, the person skilled in the art understands that these are also usable with other types of vehicle such as vans, vans, etc.

The terms “front”, “rear”, “top”, “bottom”, “transverse” are understood in relation to the vehicle. When they apply to a component, they are understood for the component integrated into the vehicle.

In reference to the , a motor vehicle 1 comprises a safety system with a controller 3 of the vehicle 1, such as an advanced driver assistance system, commonly called ADAS (for "Advanced driver-assistance systems" according to English terminology) which makes all driving decisions based on the environment and the programmed destination. The motor vehicle is then described as an autonomous motor vehicle. But it can also be a centralized vehicle management system including, or not, driving aids.

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

Controller 3 is connected to a module 5 which allows the geographical position of vehicle 1 to be known. For example, module 5 is a GNSS module (for “Geolocation and Navigation by a Satellite System”).

The controller 3 is also connected to an interface 7 allowing a user to enter information. The interface 7 is integrated into the dashboard of the vehicle 1. The interface 7 comprises in particular an input page, access to which is limited by the prior entry of an access code. This input page allows a user to choose at least one parameter from a duration of use, a distance of use and a zone of use.

The controller 3 includes a module 9 for managing the vehicle speed. This module 9 is, for example, the engine management computer of the vehicle 1.

By transmitting a specific order to the speed management module 9, the controller 3 is adapted to limit the vehicle's driving capabilities when the input parameter is exceeded by the vehicle. Thus, the controller 3 can request from the module 9 that the maximum speed of the vehicle be progressively reduced until the vehicle comes to a complete stop.

The controller 3 is also connected to a transmitter 11 which can transmit messages to the owner of the vehicle 1 or to a monitoring center.

The operation of the security system is as follows, .

Before lending vehicle 1, its owner accesses interface 7, step 21, to enter his access code and choose at least one parameter from a duration of use, a distance of use and a zone of use.

If the selected parameter is a usage area, step 23, the controller records the position of vehicle 1 from the position module 5 and defines the usage area as a circle centered on the vehicle position and having a predetermined radius. The length of the radius is user-configurable.

The vehicle is then loaned, step 25, with the information that the borrower must not leave the area of use.

If vehicle 1 leaves the usage zone, step 27, information known in near real time by controller 3 thanks to position module 5, interface 9 sends, step 29, an alert message to the borrower to ask him to return to the usage zone.

If, after a predetermined time, the vehicle 1 is still outside the usage zone, step 31, the controller 3 sends, step 33, to the speed management module 9, an order for a progressive reduction in speed and, in parallel, informs the borrower, via the interface 5, that the vehicle will see its speed reduced until it stops and that, consequently, it must look for a place to park. The speed reduction is progressive so as to avoid any risk and allow the borrower to drive the vehicle to a safe place for parking.

When the vehicle is stationary, controller 3 sends a message, step 35, via transmitter 11 to the lender with the position of the vehicle so that the latter can come and collect it.

If the chosen parameter is a duration or distance of use, the vehicle is loaned, step 37, with the information that the borrower must only use the vehicle for the duration or distance planned, at most.

If the vehicle exceeds this parameter, step 39, the system performs step 33 and beyond as described above.

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

The computers can be implemented by any type of data processing device, such as a central computing unit, a signal processing processor, an application-specific integrated circuit, a programmable gate array, etc. The computers can be implemented as a single controller, or a plurality of controllers or computers.

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 may include modules or units distributed in the form of procedures, functions, etc. Memories may be any type of storage circuit. They may be part of the processor circuit, or separate from it and connected via electrical data links. These may be non-volatile memories, hard disks, random access memories, flash memories, 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 the memory are such that, when executed by the computer, the latter carries out one or more of the steps of the methods described above.

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

The interface can be visual, for example a touch screen, or audio, for example with a synthesized voice and speech recognition, or a combination of both.
