Augmented reality display of brake lights for occluded road users

By using information exchange between vehicles behind and in front and augmented reality technology, the problem of vehicles behind being unable to recognize braking information in obstructed conditions has been solved, enabling earlier braking warnings, reducing the risk of rear-end collisions, and improving driving safety.

Abstract

The invention relates to a method comprising the steps of: determining (S1) by a rear vehicle (3) a license plate number of a front vehicle (1), comparing (S2) the license plate number with a central database (7) to confirm whether a pre-registration is present, and if such a pre-registration is confirmed: sending (S3) a request to detect (S4) whether the absolute position of the front vehicle (1) and the absolute position of the rear vehicle (3) are within a specified common area, and if it is determined that this is indeed the case: transmitting (S5) by the front vehicle (1) sensor information about another road user (5) to the rear vehicle (3), analyzing (S6) the transmitted sensor information to determine whether the brake light of the other road user (5) is activated, and if it is identified that the brake light is activated, while the rear vehicle (3) confirms that the brake light of the front vehicle (1) is not activated during this time: displaying for the driver of the rear vehicle (3) with augmented reality a symbol of the activated brake light that is fixed in relation to the position of the front vehicle (1).
