摘要:
Die Erfindung betrifft ein Verfahren zur Überprüfung eines Umfelderfassungssystems eines Fahrzeugs (10), wobei das Umfelderfassungssystem mindestens zwei verschiedene Umfeldsensortypen (12, 14) umfasst und wobei Objekte im Umfeld des Fahrzeugs (10) mit einem ersten Umfeldsensortyp (12) erfasst werden, die Objekte mit den Daten des ersten Umfeldsensortyps (12) in statische und dynamische Objekte kategorisiert werden, die relative Position der erfassten statischen Objekte zum Fahrzeug (10) bestimmt wird, diese Position mit einer über einen zweiten Umfeldsensortyp (14) ermittelten Position verglichen wird und bei einer Abweichung über einem Grenzwert auf einen Fehler geschlossen wird, wobei der Sichtbereich (18) des ersten Umfeldsensortyps (12) nicht mit dem Sichtbereich (20) des zweiten Umfeldsensortyps (14) überlappt und die relative Position der erfassten statischen Objekte nach dem Verlassen des Sichtbereichs (18) des ersten Umfeldsensortyps (12) unter Berücksichtigung der Bewegung des Fahrzeugs (10) aktualisiert wird. Des Weiteren betrifft die Erfindung ein Computerprogramm und eine Vorrichtung zur Durchführung des Verfahrens.
摘要:
A robot cleaner including a sensor module may provide accurate sensing of an obstacle and prevent an erroneous sensing of an obstacle. The robot cleaner may include a body including a cleaning unit to remove foreign substances from a surface of a floor, a cover to cover an upper portion of the body, a sensor module including an obstacle sensor mounted to sense an obstacle, and a sensor window provided at one side of the sensor module. The sensor module may include a light emitting device to emit light through the sensor window, a light receiving reflector on which light reflected from the obstacle is incident, and a light shielding portion interposed between the light emitting device and the light receiving reflector to block the light emitted from the light emitting device from being incident upon the light receiving reflector.

The invention relates to an optical measuring device (1) with a housing (3), in which at least one optical transmitter (20) for emitting at least one transmission beam (22, 24) and at least one optical receiver are arranged, wherein a cover disk (5) closes off the housing and forms a transmission window (10) and a reception window (7), wherein the at least one transmission beam (22, 24) exits from the housing through the transmission window (10). In order to provide a measuring device (1) with as flat an outer surface (14) as possible and to achieve a reduction of interference signals, which can be ascribed to reflections of the transmission beam (22, 24) on the transmission window (10) among other factors, the exterior side (5.1) of a cover disc (5) is arranged essentially perpendicular to the emission direction and the transmission window (10) is designed with an inclination that has a predetermined angle of inclination (α).

A vehicle (12) with an accident prevention system 10 is disclosed. The vehicle (12) includes a vehicle body (30). The vehicle (12) also has a foot brake (42) for stopping the vehicle (12). The system (10) includes a sensor arrangement (14) for sensing an object behind a rear end (38) of the vehicle (12) that generates an object recognition signal when it senses an object within range behind the vehicle (12). The sensor arrangement (14) includes passive IR sensors (15) or reflected pulse sensors such as sonar or radar sensors (50) on the rear end (38). A controller (20) generates an accident prevention response signal on receiving an object recognition signal from the sensor arrangement (14). A brake applicator (26) is operatively coupled to the brake (42) to stop the vehicle (12) when the controller (20) generates an accident prevention response signal. Conveniently the system (10) also includes an alarm (22) for sounding an alarm signal at the same time. The system (12) is useful for preventing an accident where a vehicle that is reversing a low speed collides with a person.

An other-vehicle detector 18 of an other-vehicle detection device 10a detects an other-vehicle VO around a host vehicle VM based on the predetermined feature amount. A detection reference value adjustment unit 16 of the other-vehicle detection device 10a, regarding the feature amount for detecting the other-vehicle VO around the host vehicle VM, changes a threshold value of the feature amount for detecting the other-vehicle VO, and detects the other-vehicle VO, based on a relative positional relationship between the other-vehicle VO and the host vehicle VM. In this way, it is possible to detect the existence of the other-vehicle VO according to the situation more.

A laser radar device (100) mounted on a vehicle includes a first laser emission part (R1-R4) configured to generate a measuring laser beam (L2) by using a laser beam (L0) emitted from a laser source (21) and to illuminate a predetermined area in a front traveling direction and a second laser emission part (R5, R6) configured to generate a measuring laser beam (L2) by using the laser beam (L0) emitted from the laser source (21). A beam spread angle (α), viewed from a side of the vehicle, of the measuring laser beam (L25, L26) generated by the second laser emission part (R5, R6) is larger than a beam spread angle (θ), viewed from a side of the vehicle, of the measuring laser beam (L21-L24) generated by the first laser emission part (R1-R4).
