Definitions
- the invention relates to the field of lighting for autonomous vehicles, in particular those with electric or hybrid propulsion.
- the object of the present invention is to remedy the drawbacks of the state of the art, and more particularly those set out above, by proposing a method for managing the lighting of an autonomous vehicle comprising an electric or hybrid propulsion which can increase the range of the vehicle.
- the invention relates to a method of managing the lighting of a motor vehicle capable of operating in an autonomous driving mode, hereinafter the host vehicle, the method comprising the steps of:
- the threshold value being less than the expected illumination intensity when the vehicle is manually driven.
- the method according to the invention makes it possible to greatly limit the intensity of the lighting of the vehicle as soon as the latter is in an autonomous driving mode. This reduction does not come at the expense of the driver since in the autonomous driving mode, neither his intervention nor his attention is required. This reduction in lighting intensity results in a reduction in electric consumption due to the vehicle's lighting system, which results in an improvement in the range of the latter.
- the threshold value corresponds to the minimum lighting intensity imposed by local regulations, that is to say the regulations in force at the location where the host vehicle is traveling.
- the threshold value corresponds to the minimum lighting intensity imposed by the most stringent regulation among a group made up of regulations from several geographical areas, for example regulations in Europe and the United States.
- the illumination intensity of the tail lights is not diminished when the host vehicle is in an autonomous driving mode if a vehicle is detected behind the host vehicle.
- the illumination intensity of the front and rear lights is decreased.
- the invention also relates to a computer program product comprising instructions which, when the program is executed by a computer, lead the latter to implement the steps of the method as defined above.
- the invention also relates to an autonomous driving system comprising a computer, at least one sensor and actuators arranged to implement the method as defined above.
- the invention also relates to a motor vehicle equipped with an autonomous driving system as defined above and / or implementing a method as defined above.
- the motor vehicle comprises an electric or hybrid electric propulsion.
- FIG. 1 represents a vehicle equipped with an autonomous driving system allowing the implementation of a method according to the invention.
- FIG. 2 is a diagram showing an autonomous vehicle implementing the method according to the invention.
- FIG. 1 represents a motor vehicle capable of implementing an autonomous driving mode, and which is for this purpose equipped with an autonomous driving system 2.
- this vehicle will be referred to as the host vehicle 1.
- the autonomous driving system 2 comprises in particular a computer 10, actuators 12, as well as a plurality of sensors 14a, 14b, 16a, 16b, 18 distributed over the front, rear and sides of the host vehicle 1.
- sensors can include one or more of the following types of sensors: ultrasonic sensors, radars, lidars, day vision cameras, night vision cameras, etc.
- the autonomous driving system 2 comprises in the example four cameras 18 (either a front camera, a rear camera and two side cameras) and a plurality of sensors 14a, 14b, 16a, 16b of the ultrasonic and / or radar sensor type and / or lidar.
- the computer 10 receives the data provided by all of the sensors 14a, 14b, 16a, 16b and by all of the cameras 18.
- the computer 10 is able to detect the presence of obstacles in the environment of the host vehicle 1, and in particular the presence of vehicles in this environment, whether on the current track of the host vehicle. 1 or on adjacent lanes.
- the computer 10 is also connected to a plurality of actuators 12, which include devices capable of acting in particular on the accelerator and the braking system of the host vehicle, in order to control their speed.
- the actuators 12 also include devices capable of acting on the direction of the vehicle in order to control its trajectory.
- the autonomous driving system is configured to implement the method according to the invention.
- the intervention and attention of the driver is no longer required. It is therefore possible to reduce the intensity of the lighting supplied by the vehicle lighting system (not shown), which is controlled by the computer 10, without disturbing the driver (who will moreover very probably be occupied by entertainment. provided on board the vehicle).
- the intensity of the lighting is reduced to a threshold value, this threshold value corresponding to the minimum value imposed by the regulations in force.
- the minimum value is determined according to local regulations, that is that is to say the regulations in force at the location where the host vehicle 1 is traveling, the vehicle being geolocated.
- the minimum value may correspond to the greater of the minimum values set by the regulations in force in different geographical areas, for example Europe and the United States.
- FIG. 2 shows a road comprising two traffic lanes, on which circulate several vehicles including the host vehicle 1.
- the host vehicle 1 is in an autonomous driving mode, and the intensity of illumination of the front and rear lights is reduced in accordance with the invention, which is not the case with other vehicles 3, 4, which are conventional vehicles. It can therefore be seen that the front 20 and rear 22 light panels of the host vehicle 1 are less intense than the light beams 30, 32, 40, 42 of conventional vehicles 3, 4.
- the lighting intensity is changed for both the front and rear lights. Provision can however be made that, when a vehicle following the host vehicle 1 is detected, then only the lighting intensity of the front lights is reduced, in order to keep the host vehicle 1 more visible to the vehicle or vehicles following it. .
- the method of the invention therefore makes it possible to greatly limit the intensity of the lighting as soon as the host vehicle is in an autonomous driving mode.
- This management of vehicle lighting automatically results in a reduction in electricity consumption and therefore in an improvement in the autonomy of the autonomous vehicle since the battery is used less. It is estimated that a 30% decrease in lighting intensity can easily be achieved in the process of the invention.
