Definitions
- This invention is related to the field of vehicle lighting systems, and more particularly to the management of control image data of pixelated lighting sources of a motor vehicle.
- Lighting systems for current motor vehicles include light sources that now make it possible to project a high-definition light beam.
- the desired projection of high definition light can be obtained through the light sources and from images, or image patterns, that the sources receive in order to display them and thus project a given light beam.
- These images or image patterns can reach very high resolutions, especially depending on the resolution of the light source used.
- the light source can have at least 4,000 to 30,000 pixels, thus making it possible to generate a light beam from an image of this level of resolution.
- Micro-mirrors whose position is controlled by means of piezoelectric elements, are oriented so as to selectively reflecting an incident light beam, so that each micro-mirror corresponds to an elementary source of the matrix of pixels thus generated.
- the light coming from a source is directed onto the matrix of micro-mirrors by an optic.
- the light emitted by a matrix light source also generally passes through an optic comprising at least one optical lens, to project the desired outline in front of the motor vehicle.
- an optic comprising at least one optical lens
- the response of the elementary light sources of the matrix through the optical system is not homogeneous.
- a central zone is able to project at a high resolution, while the resolution gradually decreases near the field of view of the light source, which can all the more have a large aperture of the order of 35°.
- the projection of precise contours in areas of lower resolution i.e. at the edges of the field of view
- the result of projecting a precise outline or pattern into such an area is usually a blurred outline or pattern.
- a motor vehicle therefore embeds more and more light sources, which use increasingly heavy high-definition image data, which involves a large amount of data that must be managed by a vehicle control system.
- automotive and communicated via a transmission medium between the control system and the light source(s).
- a data bus of CAN (Car Area Network) protocol type is often used to transfer such data between the control system and the light source.
- CAN Car Area Network
- these means of data transmission have the disadvantage of having a limited bandwidth, not allowing for example to exceed a rate of 2 to 5 Mbps generally.
- difficulties may arise in transmitting over these limited networks the large amount of data required for the aforementioned high definition images.
- these networks are also used for the communication of other vehicle data, which means that the bandwidth available for high definition image data can be further reduced, for example by being limited to a range of 70 to 90% of the maximum throughput possible on the data transmission network.
