Roadside detection system, driver assistance system and roadside detecting method

摘要

A roadside detection system installed in a vehicle to detect a roadside of a road on which the vehicle travels includes detection results acquiring means, first edge line detecting means and second edge line detecting means. The detection results acquiring means emits light waves or electromagnetic waves to a target detection region in which an object to be measured is detected and acquires an objective distance and a reflection intensity, for each of separate regions obtained by separating the target detection region into a plurality of divisions. The first edge line detecting means detects a first edge line that is a candidate of a roadside based on each objective distance. The second edge line detecting means detects a second edge line that is a candidate of a roadside based on each reflection intensity. A driver assistance system and a roadside detecting method are also provided.

1. A roadside detection system installed in a vehicle to detect a roadside of a road on which the vehicle travels, the system comprising:
acquiring means that emits light waves or electromagnetic waves to a target detection region in which an object to be measured is detected and acquires, as an objective distance, a distance to the object to be measured from a reflected wave reflected from the object to be measured and, as a reflection intensity, an intensity of the reflected wave, for each of separate regions obtained by separating the target detection region into a plurality of divisions; first edge line detecting means that detects a first edge line that is a candidate of the roadside based on each objective distance, the first edge line being a physical edge line that indicates that the vehicle will run off the road or cause a collision when the vehicle crosses over the physical edge line; and second edge line detecting means that detects a second edge line that is a candidate of the roadside based on each reflection intensity, the second edge indicating a legal edge line drawn between the road and a region which is outside the road.
