Description

Title of the invention: Method for playing music in a motor vehicle. Technical field

[0001] The present invention relates to a method of broadcasting music in a motor vehicle, a device for broadcasting music in a motor vehicle, a motor vehicle comprising such a device and a computer program product. State of the art

[0002] Currently, a multimedia function found in every motor vehicle is the sound playback function and, more specifically, the music playback function. The sound sources are multiple: radio, local storage via a USB key (Universal Serial Bus), streaming software, etc.

[0003] Typically, the user manually selects from multiple sources the sound sequence(s) they wish to listen to, either individually or grouped together as a playlist.

[0004] There is therefore a real need for a method and system for broadcasting music in a motor vehicle that automates all or part of the selection of sound sequences based on various parameters, including user preferences. Description of the invention

[0005] To overcome one or more of the aforementioned drawbacks, according to a first embodiment, a method for broadcasting music in a motor vehicle is implemented by a processor and comprises the steps performed in real time of: • collection of vehicle traffic parameters including steering wheel angle and rotation speed; • generating music using the collected parameters as input parameters; • broadcasting of the generated music.

[0006] Thus, the music played is automatically selected according to the selected parameters.

[0007] Specific features or embodiments, usable alone or in combination, are: • Music generation also uses parameters associated with the environment in which the vehicle is located; • Music generation also uses parameters associated with a user of the motor vehicle; • The traffic parameters collected also include the speed of the motor vehicle and the tempo of the generated music is correlated to the speed; and / or • Music generation includes a database of audio sequences, with an audio sequence being selected for playback based on collected parameters.

[0008] In a second embodiment, a device includes a memory associated with at least one processor configured to implement the method of the first embodiment.

[0009] In a third embodiment, a motor vehicle includes a device according to the second embodiment

[0010] In a fourth embodiment, a computer program includes instructions which, when the program is executed by the device according to the second embodiment, lead the device to implement the process according to the first embodiment. Brief description of the figures

[0011] 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 music playback system according to one embodiment; and • [Fig.2] represents a flowchart of a music broadcasting process according to a particular embodiment. Methods of implementation

[0012] 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. Other applications such as a robot in a warehouse or a motorcycle on a country road are also conceivable.

[0013] The terms "front", "rear", "top", "bottom", "transverse" are understood in relation to the vehicle.

[0014] Fig. 1 represents a motor vehicle 101 comprising a music playback device 103. The device 103 includes a computer 105 connected to a database 107 of sound sequences and an input interface 109 to the vehicle management systems 101. The computer 105 is also connected to a sound amplification and playback device 111, typically loudspeakers.

[0015] For example, the input interface 109 can receive the following data: vehicle position or geographic location, vehicle speed and / or acceleration, setpoint or predetermined positions / speeds / accelerations, engine speed, position and / or travel of the clutch, brake, and / or accelerator pedals, detection of other vehicles or objects, position or geographic location of other detected vehicles or objects, speed and / or acceleration of other detected vehicles or objects, sensor operating states, and the confidence level of data from or processed by sensors. In particular, the interface 109 receives the angular position and rotational speed of the steering wheel.

[0016] The operation of device 103 is as follows, [Fig.2].

[0017] In step 201, the device 103 receives via the input interface 109 traffic parameters of the motor vehicle 101, including the angle and speed of rotation of its steering wheel.

[0018] Advantageously, the device 103 can also receive parameters associated with the environment in which the vehicle 101 is located. For example, is the vehicle crossing a forest? or is it passing through a tunnel?

[0019] Optionally, the device 103 can also receive parameters about the user such as their mood, fatigue level, music preferences, etc.

[0020] Device 103 uses the received parameters as input parameters to generate music, step 203. For example, depending on the vehicle's speed, device 103 will search database 107 for music with a faster or slower tempo. As another example, device 103 uses the steering wheel's rotation (angle and speed) to determine whether the vehicle is traveling on a relatively straight road, such as a highway, or on a small, winding mountain road. In the first case, the device selects sound sequences that will keep the driver alert, while in the second case, it selects sound sequences that optimize the driver's concentration on driving without overloading their cognitive system.

[0021] Then the music is broadcast, step 205, via the 111 device.

[0022] Figure 1 illustrates a system according to certain embodiments. The breakdown presented is for pedagogical purposes to highlight the different functions. However, it is understood that each block can be implemented using different means or combinations thereof, such as hardware components, software, one or more computers, and / or electronic circuits. Each component may include at least one computer or a control unit. At least one memory may be included in each component. The memory may include computer program instructions or software code.

[0023] The computers can be implemented by 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. The computers can be implemented in the form of a single controller, or a plurality of controllers or computers.

[0024] The different modules are connected to each other by data links adapted to the environment. These can be wired, electrical or optical, or wireless.

[0025] For the software, the implementation may comprise modules or units distributed in the form of procedures, functions, etc. The 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 drives, RAM, flash memory, etc.

[0026] The software product can be downloaded from a communication network and / or stored on a computer-readable medium. It can be directly executable by a processor or be in the form of a high-level language requiring one or more intermediate operations to be executable.

[0027] Thus, the program instructions stored in memory and processed by the computers can be any type of program code, for example, a compiled or interpreted program written in a suitable programming language.

[0028] 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.

[0029] The invention has been illustrated and described in detail in the drawings and the preceding description. This description is to be considered illustrative and given by way of example and not as limiting the invention to this single description. Numerous embodiments are possible.

[0030] For example, the process has been described as a sequence of steps. Some steps can be carried out in parallel or in a different sequence.

[0031] In a first variant, the sound sequence database 107 is located in a server connected to the device 103 by a 4G / 5G telephone-type wireless data link.

[0032] In a second variant, the music generation uses the FMOD module of the UNITY software from UNITY TECHNOLOGIES inc.
