Driving assistance system
A driving assistance system includes an illumination apparatus and a controller. The illumination apparatus is configured to draw an avoidance pattern PTN on a road surface such that it indicates a lane in which the driver's vehicle is to travel or a direction in which the driver's vehicle is to travel. Upon detecting, by a sensor or communication, an obstacle in front of the driver's vehicle, the controller instructs the illumination apparatus to draw the avoidance pattern PTN.
1. A driving assistance system comprising:
an illumination apparatus structured to draw a pattern which is visible to a driver on a road surface when an obstacle exists in front of the driver's vehicle, wherein the pattern indicates a lane in which the driver's vehicle is to travel in order to avoid the obstacle or a direction in which the driver's vehicle is to travel in order to avoid the obstacle; and
a controller structured to instruct the illumination apparatus to draw the pattern upon detecting, by means of a sensor or communication, the obstacle in front of the driver's vehicle.
2. The driving assistance system according to claim 1 , wherein the controller instructs the illumination apparatus to draw the pattern on a near side of a point at a stopping distance to the obstacle.
3. The driving assistance system according to claim 2 , wherein, when a distance between the driver's vehicle and the obstacle becomes smaller than the stopping distance, the controller notifies the driver of this information.
4. The driving assistance system according to claim 1 , wherein the controller adjusts a drawing timing of the pattern according to a surrounding situation.
5. The driving assistance system according to claim 4 , wherein the controller is structured to detect an overtaking vehicle approaching from behind the driver's vehicle,
and wherein, upon detecting the overtaking vehicle, after completion of overtaking, the controller issues an instruction to draw the pattern.
6. An automotive lamp provided with the driving assistance system according to claim 1 .
7. A vehicle provided with the driving assistance system according to claim 1 .
