Abstract
An object detection device for detecting objects in a rear lateral area of a vehicle includes zero-contact radiation-based scanners for scanning such area, and an evaluation unit connected to the scanners. According to the invention, the evaluation unit evaluates the time sequence of the scanning information from two or more strip-shaped portions of the area under observation, with horizontal components that are differently inclined to the lengthwise direction of the vehicle or are offset from one another in the lengthwise direction of the vehicle. The evaluation unit distinguishes objects moving in the travel direction of the vehicle from standing and oncoming objects, based on the response sequence for the portion under observation.
Claims4
Vehicle with an object detection device for detecting objects in an area adjacent the vehicle, comprising:
- scanner means for radiation-based scanning of strip shaped portions of said area;
- and
- an evaluation unit connected to the scanner means;
- wherein
- the evaluation unit evaluates a time sequence of scanning information from the scanner means for at least two strip-shaped portions of said area, said at least two strip shaped portions having horizontal components that are at least one of inclined differently to a lengthwise direction of the vehicle and offset with respect to one another in the lengthwise direction of the vehicle;
- and
- on the basis of a response sequence for said at least two strip shaped portions, the evaluation unit distinguishes objects moving in a travel direction of the vehicle from objects that are at rest or oncoming.
An object detection device for a vehicle, comprising:
- a scanner arrangement for radiation based scanning of an area adjacent the vehicle, said scanning arrangement comprising a plurality of scanners, each of which scans a different elongate portion of said area, each said elongate portion having a horizontal longitudinal axis which is at least one of inclined differently from other elongate portions relative to a lengthwise direction of the vehicle, and offset relative to the other elongate portions in the lengthwise direction of the vehicle;
- and
- an evaluation unit connected to the scanner arrangement to receive time sequence scanning information from each scanner concerning objects detected in an area which it scans;
- wherein said evaluation unit evaluates said time sequence scanning information from at least two scanners and distinguishes objects moving in a travel direction of the vehicle from objects which are at rest or oncoming, based on a response sequence of signals from said at least two sensors.
