The invention ensures a clear and relevant presentation of navigation data, while harmoniously integrating the display devices into the vehicle.

[0023] By eliminating the need for the driver to change display settings while driving, the invention significantly reduces distractions and the risks associated with loss of attention on the road. Thus, it improves both the driving experience and road safety. Brief description of the drawings

[0024] [Fig.1] represents a schematic view of a dashboard of a motor vehicle configured to perform a method of managing a guidance system according to the invention. Detailed description

[0025] Figure 1 shows a simplified view of a human-machine interface 3 of a motor vehicle 2, comprising a console screen 4 that can be positioned in the center of the dashboard. The interface 3 also preferably comprises an instrument display 6, which can be positioned behind the steering wheel of said vehicle.

[0026] The motor vehicle 2 is equipped with a guidance system, said motor vehicle 2 being configured to perform a method of managing the motor vehicle guidance system according to the present invention.

[0027] The method for managing the vehicle guidance system comprises several steps. First, guidance for a vehicle route is selected. Next, the type of route is identified as either urban or extra-urban navigation. The selected guidance is then initiated for execution by the vehicle. Finally, one of two pre-recorded layouts 8 is displayed on the vehicle's console screen 4 and / or instrument panel screen 6, depending on the identified route type.

[0028] Guidance selection can be performed from a smartphone or directly from the motor vehicle. A computer program comprising computer-readable code instructions is used to implement the guidance system management method. This computer program is stored on a computer-readable storage medium.

[0029] Advantageously, the pre-recorded layouts 8 are specific display configurations that are selected according to the type of journey. These layouts may include a first display layout 8 for urban navigation with sequential navigation instructions for urban navigation, incorporating, for example, guidance arrows indicating the direction to take. The pre-recorded layouts may also include a second display layout 8 for extra-urban navigation with a driver assistance view for extra-urban navigation, which may, for example, include a modeled view of the motor vehicle in real time within the lane, possibly with a visualization of the distance separating it from a vehicle ahead.

[0030] Extra-urban navigation, as opposed to urban navigation, refers to any movement made by the motor vehicle outside of urban areas, which may include motorways, departmental, national, rural or country roads.

[0031] Preferably, the pre-recorded layout 8 is automatically selected when the guidance is started, and is displayed on the instrument screen 6 to provide relevant information to the driver depending on the type of journey.

[0032] The layout selected after the guidance system is launched can alternatively be displayed on the console screen 4, or displayed on both the console screen 4 and the instrument display 6. Preferably, the display selection on the console screen 4 and / or on the instrument display 6 can be made from a smartphone or directly from the motor vehicle.

[0033] The method according to the invention preferably comprises a display on the console screen 4 of an auxiliary arrangement 10, which is an additional display configuration that can include information such as the vehicle's driving speed and / or speed limit, etc.

[0034] Preferably, the auxiliary arrangement 10 occupies at most half of the total display area of ​​the console screen 4 and is arranged on a transverse half of the console screen close to the steering wheel (not shown) of the motor vehicle 2. Thus, the auxiliary arrangement 10 on the console screen 4 is located within sight and reach of the driver.

[0035] In one example, the driver can choose, from their living room and using their mobile phone, for an extra-urban (highway) journey, to activate the second display layout with a driver assistance view on the instrument screen. For a city journey, they can opt for the simplified display of the first layout with only the speed and sequential turn-by-turn directions.

[0036] Thus, when the driver makes a home-work journey via the motorway, he preconfigures in his preferences the driving assistance view on the instrument screen 6, which will be automatically activated as soon as the navigation is launched in the motor vehicle 2.

[0037] However, when the driver travels from home to another destination without using the motorway and via the city, the simplified configuration with only the speed and turn-by-turn directions will appear. The driver can also choose to deactivate these personalized settings. The information from the auxiliary layout 10 displayed on the console screen 6 can remain unchanged when the instrument display 6 switches between the first and second layouts.

[0038] Advantageously, the present invention allows for better adaptation of guidance information according to the type of journey, a clear and relevant presentation of navigation information, and a harmonious integration of display devices in the vehicle. This makes it possible to solve the problems related to to information overload and driver distraction, while improving driving experience and safety.
