Abstract

The invention relates to a driving aid system incorporated into a vehicle comprising a windshield, the system comprising visual information that is not visible, disposed at several predefined locations on the windshield and a lighting device able to illuminate each of the predefined locations so as to cause the appearance thereat of the corresponding visual information in the field of vision of the driver. The visual information comprises at least a first group of identical information, and the system further comprises a unit for detecting the ocular point of the driver providing directional information to the light device which is adjusted so as to illuminate, depending on the directional information received, the predefined location of one of the items of information of the first group, situated in correspondence with the ocular point of the driver detected.

Claims

1-11. -11. (canceled)

12. A driving assistance system incorporated in a vehicle including a windscreen, said system comprising:

non-visible, visual information, arranged in several predefined locations on the windscreen, the visual information comprising at least one first group of identical information;

a lighting device suitable for illuminating each of the predefined locations in order to display the corresponding visual information in the vision field of the driver; and

a detection unit of the ocular point of the driver structured and operable to supply directional information to the lighting device, whereby the lighting device is adjusted to illuminate, according to the received directional information, the predefined location of information of the first group, situated in correspondence with the detected ocular point of the driver.

13. The driving assistance system according to claim 12, wherein the first group comprises at least two identical visual pieces of information arranged one above the other.

14. The driving assistance system according to claim 13, wherein the first group comprises at least three pictograms comprising an upper pictogram, a median pictogram and a lower pictogram, arranged one above the other.

15. The driving assistance system according to claim 14, wherein the detection unit of the ocular point of the driver supplies high, median or low directional information, while the lighting device illuminates respectively the upper, median or lower pictogram.

16.
