Definitions
- the invention relates to the field of information exchange in a motor vehicle and more particularly to an adaptation device making it possible to facilitate the exchange of information between a vehicle and an element integrated in the vehicle such as a multimedia system. .
- a motor vehicle is generally designed for an average of five to seven years and incorporates several electronic systems.
- a multimedia system has a shorter life span than a vehicle, usually two to three years before being replaced.
- the protocols used to exchange data or information between the various multimedia systems and the vehicle are generally determined for a given vehicle range. These data come from various sensors or computers and relate for example to the state of the vehicle or systems integrated into the vehicle. Gateways can be used to communicate between embedded networks of different technologies. Thus, initially, various data transit to a gateway for example via the CAN bus of the vehicle. This data is then translated through conversion functions integrated into the gateway and sent via the vehicle's CAN bus or any other network to the different systems involved in the information in the appropriate format.
- Conversion and data transmissions are performed for a given vehicle, and for a given system.
- the integration of new multimedia services in an existing vehicle may require the provision by the vehicle of information not requested by the existing multimedia services or the provision by the new multimedia system of information in an old format . From one vehicle to another or from one multimedia system to another, this information can circulate on embedded networks under various formats or transit on dedicated wires also in various formats. Poorly controlled, the adaptations required by this integration can impact a large number of computers, both the vehicle and the multimedia system, and are expensive.
- standardizing the interface between all vehicles and all multimedia systems does not manage independent changes in the format and content of vehicle information on the one hand and the format and content of information multimedia systems on the other hand. .
- an object of the invention is to propose a device making it possible to isolate the two vehicle and multimedia worlds from one another, and to manage the adaptation of a new multimedia system to a range. of different vehicles through a single piece.
- the subject of the invention is an adaptation device intended to be arranged in a vehicle between a vehicle computer and a computer of a second element integrated in said vehicle for exchanging information between them, characterized in that the device comprises a first vehicle interface means connected to a dedicated wire of the vehicle and a second vehicle interface means connected to a network of the vehicle, and in that it comprises a first second element interface means connected to a a second element network and second second element interface means connected to a dedicated wire of the second element.
- Such a device allows a vehicle and a multimedia system to evolve independently of one another.
- the appearance of a new multimedia system can advantageously be integrated into a defined vehicle, produced in series without questioning the electrical or electronic architecture of the vehicle.
- Such a device makes it possible to exchange information circulating not only on a network but also information circulating on dedicated wires. It allows for example to transform information flowing on the CAN bus of the vehicle in wire information and vice versa.
- This device allows to concentrate on a single piece the need for information exchange from one world to another and the translation of the format and content of this information.
- a device can acquire information from networks, for example CAN, Flexray, LIN, MOST, IEEE1394, or wired inputs, such as, for example, the voltage level, the current level, a PWM signal, according to the modalities specific to each type of information and medium. It converts a format and content to another format and content, and retransmits the information converted on networks or wired outputs, according to the terms specific to each type of information and medium.
- Such a device may be required to memorize the value of each piece of information received or converted, for example to overcome faults in the information acquisition chain or to adapt the methods of receiving and transmitting information from an input or from a data source. a network with an output or another network.
- Such a device can be the subject of a dedicated room whose adaptation function varies depending on the combination (vehicle, multimedia system), be integrated into a multimedia room whose conversion function and vehicle interface varies from vehicle to vehicle or be integrated into a vehicle part whose conversion function and multimedia interface varies from one multimedia system to another.
- the device may comprise means for converting a vehicle information format into an information format of the second element and vice versa, and means for storing information transmitted by the vehicle computer and the calculator of the second element.
- the invention also relates to a method implemented by the device according to one of the preceding claims characterized in that it comprises a step during which one translates, via a format conversion means of information, an information format circulating on a vehicle network in an information format flowing on a dedicated wire of the second element and vice versa.
- the method may comprise a step during which an information format that travels over a network of the vehicle in a data format is translated, via an information format conversion means.
- the method may comprise a step during which a format of information circulating on a data format conversion means is translated through an information format conversion means; a dedicated wire of the vehicle in an information format flowing on a dedicated wire of the second element, and vice versa.
- the invention also relates to a motor vehicle comprising such an adaptation device.
- the invention also relates to the use of one or more adaptation devices for integrating a multimedia system into a vehicle
- FIG. 1 represents an adaptation device according to the invention
- FIG. 2 represents a set of multimedia systems integrated into a given vehicle model
- FIG. 3 represents the adaptation device implemented to add new multimedia systems (S3, S4) in a vehicle V1,
- FIG. 4 represents the adaptation device implemented for integrating multimedia systems (S1, S2, S3) of a vehicle V1 into a vehicle V2;
- FIG. 5 represents an adaptation device implemented to integrate multimedia systems of a vehicle V1, in a vehicle V2 to which new multimedia systems are added.
- FIG. 1 shows the block diagram of a device 1 enabling a given vehicle (not shown) to adapt to the technological evolution of elements to be integrated into the vehicle, for example multimedia systems and allowing conversely to these elements to adapt to the evolutions of a vehicle.
- the device 1 is arranged between a vehicle computer and for example a multimedia system computer.
- This adaptation device 1 is intended to serve as a multimedia and / or vehicle evolution interface. When a multimedia system must for example be arranged on vehicles of different range, it is not necessary to redevelop an electrical architecture for each vehicle.
- the adaptation device 1 makes the connection between the vehicle and the multimedia system.
- the adaptation device 1, or gateway 1 allows the exchange of information between the vehicle and a multimedia system (not shown) integrated in the vehicle.
- the gateway 1 comprises interface means: a multimedia interface 3 allowing the communication and the exchange of data between the computer or computers of the multimedia system and the gateway on the one hand, and a vehicle interface 2 allowing the communication and the data exchange between the vehicle and the gateway 1 on the other hand.
- a multimedia interface 3 allowing the communication and the exchange of data between the computer or computers of the multimedia system and the gateway on the one hand
- vehicle interface 2 allowing the communication and the data exchange between the vehicle and the gateway 1 on the other hand.
- the multimedia system may include one or more elements.
- the vehicle interface 2 more precisely comprises first vehicle interface means 20 which are vehicle input / output interfaces 20 connected to dedicated wire links or wires 22 of the vehicle - that is to say a wire where only information circulates - and second vehicle interface means 21 which are vehicle network interfaces 21 connected to one or more networks 23 of the vehicle such as the CAN network of the vehicle.
- the multimedia interface 3 comprises first multimedia interface means
- multimedia input / output interfaces 30 connected to dedicated wire or wire links 32 of the multimedia system and second multimedia interface means 21 which are second multimedia network interfaces 31 connected to one or more networks 33 of the system multimedia, for example the CAN multimedia network.
- CAN network examples are given by way of non-limiting example.
- the gateway 1 comprises connectors 5 and 6 able to connect on the one hand the vehicle input / output interfaces 20 and the multimedia input / output interfaces 30 respectively to the wired links of the vehicle 22 and the multimedia system 32, and to on the other hand connect the vehicle network interfaces 21 and the multimedia network interfaces 32 respectively to the networks of the vehicle 23 and the multimedia system 33.
- the wired links 22 of the vehicle are not directly connected to the multimedia system but to the gateway 1 and more particularly at the vehicle input / output interface.
- the wired links coming from the multimedia system are not directly connected to the computers of the vehicle but to the gateway 1, and more precisely to the interface 30 of multimedia inputs / outputs.
- the CAN network of the vehicle for example is not connected directly to the computers of the multimedia system but on the gateway 1 via the vehicle CAN interface 3.
- the multimedia computers are connected to a second network CAN connected to the gateway 1 via a multimedia CAN interface.
- the gateway 1 comprises processing means 4 and storage 5 information.
- a means for processing data or information for example a microcontroller 4, is intended to communicate with the various vehicle 2 and multimedia 3 interfaces through which the vehicle and multimedia data transit. Unlike a computer that will seek the information it needs on a network, the gateway 1 is able to recover all the data that the vehicle and the multimedia system are likely to provide, and whose vehicle or multimedia system needs . It thus makes it possible to centralize all the data necessary for the communication of the vehicle with the multimedia system. All data needed are stored in memory so that the gateway 1 can send them to the vehicle or to the multimedia system.
- the microcontroller 4 receives data from the computers of the vehicle or multimedia computers via the vehicle and multimedia interfaces, and sends this data to the storage means 5.
- the data stored in the storage means 5 are converted into the data format adapted to the vehicle or multimedia system.
- Gateway 1 enables a new multimedia system or a new range of multimedia systems to be quickly and cost-effectively deployed on new and existing vehicles of different generations, concentrating all necessary adaptations in a single room. For example, when a new multimedia system needs to be integrated into a large number of new or existing models of vehicles of the same or different range, the Gateway 1 is deployed on each vehicle model with a vehicle interface. and a suitable conversion function. The multimedia interface, the format and the information content of the multimedia side are identical from one vehicle model to another, and the other parts of the multimedia system are then transversal to all vehicles without modification. When a new vehicle must receive different multimedia systems, the gateway 1 is for example deployed on each multimedia system with a multimedia interface and a suitable conversion function.
- FIG. 2 shows an example of a standardized adaptation interface on a vehicle V1 with three multimedia systems S1, S2, S3 and a suitable gateway 1.
- the multimedia system S1 comprises a display 70 and a radio 71
- the multimedia system S2 comprises a radio 80, a radio 81 and a navigation system 82
- the multimedia system S3 comprises a display 90, a radio 91, a radio navigation system 92.
- the gateway 1 may or may not be integrated in an element of the multimedia system.
- a new multimedia system S4 comprising, for example, a radio 100, a radio 101 and a navigation system 102
- the vehicle interface standard V1 may be supplemented for the purposes of the new multimedia system S4.
- the implementation of the add-in only impacts the implementation of the gateway 1 for the multimedia system S4, and does not impact the vehicle V1, nor the other multimedia systems S1, S2 and S3, nor even the other parts of the multimedia system S4.
- the gateway 1 of the multimedia system S4 uses all the information of the standardized interface of the vehicle V1 which is useful to it and which can come from the other multimedia systems S1, S2, S3.
- FIG. 2 shows an interface integration on the same vehicle V1.
- the gateway 1 is standardized on the vehicle side V1 and is adapted from the multimedia side to the multimedia interface standard of the multimedia system S4.
- the S4 multimedia system implements a specific multimedia interface and a specific conversion function.
- the integration of the same multimedia systems S1, S2 and S3 present on the vehicle V1 on another vehicle V2 does not have the same architecture as the vehicle V1 is shown in Figure 4 where the vehicle V2 defines a specific interface standard .
- the gateway 1 then implements a vehicle interface and a conversion function specific to the vehicle V2 but complies with the multimedia interface standard of the systems S1, S2 and S3.
- the vehicle V2 has no CAN network and the gateway 1 acquires wired signals replacing the necessary information.
- the multimedia systems S1, S2, S3 present in the vehicle V1 are integrated in the vehicle V2.
- the new S4 multimedia system is also integrated in this V2 vehicle.
- the gateway 1 acquires wired signals replacing the information necessary for the operation of the multimedia system S4 and converts them into the same multimedia format as on the vehicle V1.
- the other computers of both the vehicle V2 multimedia systems S1, S2, S3 and S4, are not modified.
- the gateway 1 behaves as a calculator that separates the vehicle world from that of a multimedia system and vice versa.
- This interface piece 1 can constitute a specific calculator, but can also be integrated with existing calculator.
- Another advantage of such an invention is the concentration of the adaptations to be managed in a single computer. This advantage is therefore both economic and functional optimization, thus limiting the complexity of development, evolution and integration.
