ROAD VEHICLE EMITTING A WARNING SIGNAL AND METHOD FOR MODIFYING THE WARNING SIGNAL

A road vehicle (1) is described, comprising: two or more ports (2, 3); a sensor device (10), the sensor device (10) being configured to detect for each port individually a non-finished or imminent opening event of the respective port (2, 3), the sensor device (10) also configured to output sensor signals representing the result of the detecting; a signaling device (20) comprising at least one optical transducer (21) to emit optical signals (23); a controller (30) controlling the signaling device (20) depending on the sensor signals so that the transducer (21) projects onto the surface near the vehicle a light signal (21) for each port (2, 3) for which a detected non-finished or imminent opening event is represented by sensor signals; the controller (30) further determining for each detected non-finished or imminent opening event a probability of an actual occurrence of such opening event and to modify the signal (21) for such port (2, 3) as a function of the determined probability.
