Abstract:
System and method for monitoring the physiological behaviour of a driver that includes measuring a physiological variable of a driver, assessing a driver's behavioural parameter on the basis of at least said measured physiological variable (1, 4), and informing the driver (2, 3) of the assessed driver's behavioural parameter (1, 4). The measurement of the physiological variable (1, 4) can include measuring a driver's eye movement, measuring a driver's eye-gaze direction, measuring a driver's eye-closure amount, measuring a driver's blinking movement, measuring a driver's head movement, measuring a driver's head position, measuring a driver's head orientation, measuring driver's movable facial features, and measuring a driver's facial temperature image.
Abstract:
The invention relates to a method for automatically controlling a position of a vehicle (1) relative to a road boundary (5a, 5b) extending along a road (2) on which the vehicle is driving. The method comprises the steps of determining a distance to the road boundary or an estimated time to the road boundary, determining if the distance to the road boundary is shorter than a predetermined distance or if the estimated time to the road boundary is shorter than a predetermined time, and braking at least one wheel associated with a vehicle side turned away from the road boundary and activating a retarder, if the distance to the road boundary is shorter than the predetermined distance or if the estimated time to the road boundary is shorter than the predetermined time. The invention also relates to a second method and two computer programs.
Abstract:
Vorrichtung zur Beeinflussung des Fahrverhaltens eines Kraftfahrzeugs im Sinne einer höheren Fahrsicherheit vor und während einer Kurvenfahrt, welche Umfeldgrossenermittlungsmittel (10,12,13) zur Ermittlung wenigstens einer das Fahrzeugumfeld beschreibenden Grösse enthält. Weiter enthält die Vorrichtung Gefährdungsermittlungsmittel (20), in denen abhängig von wenigstens der das Fahrzeugumfeld beschreibenden Grösse die fahrdynamische Gefährlichkeit der vorliegenden Fahrsituation ermittelt wird sowie Massnahmenbestimmungsmittel (30), in denen abhängig von der Gefährlichkeit der vorliegenden Fahrsituation Massnahmen zur Erhöhung der Fahrsicherheit bestimmt werden sowie Aktormittel(40,41,42,43,44,45), durch welche die zur Erhöhung der Fahrsicherheit bestimmten Massnahmen durchgeführt werden können. Der Kern der Erfindung besteht darin, dass Situationsbewertungsmittel (31) vorhanden sind, durch die abhängig von wenigstens einer durch die Umfeldgrossenermittlungsmittel ermittelten Grösse die Ermittlung der Gefährlichkeit der vorliegenden Fahrsituation (20) oder die Bestimmung von Massnahmen zur Erhöhung der Fahrsicherheit (30) oder die Durchführung von Massnahmen zur Erhöhung der Fahrsicherheit(40,41,42,43,44,45) aktiviert oder deaktiviert werden.
Abstract:
A multiple beam array antenna system comprises a plurality of radiating elements provided from stripline-fed open-ended waveguide coupled to a Butler matrix beam forming network. The Butler matrix beam forming network is coupled to a switched beam combining circuit. The antenna can be fabricated as a single Low Temperature Co-fired Ceramic (LTCC) circuit.
Abstract:
A near object detection (NOD) system includes a plurality of sensors, each of the sensors for providing detection coverage in a predetermined coverage zone and each of the sensors including a transmit antenna for transmitting a first RF signal, a receive antenna for receiving a second RF signal and means for sharing information between each of the plurality of sensors in the NOD system.
Abstract:
The invention relates to a system for automatic following-distance control, notably in congested traffic, in a motor vehicle (1) so as to facilitate driving in congested traffic by both taking over transverse steering by means of an automatic steering system and ensuring that a given distance is maintained to a vehicle driving ahead. The latter function calls for an adaptive driving and brake control system with a "stop" and "go" function. According to the invention selection and decision means (5, 6, 7, 8, 9) are provided for which are able to selected both control parameters and control types, for example following-distance control of the motor vehicle (1) in accordance with road markings recognized by video camera or in accordance with a detected leading vehicle. The system is divided into hierarchical levels (I-IV). The driver always remains in the monitoring and adaptation circuit assigned to the highest hierarchical level (IV) so that he has the highest priority and can overrule the system at any time.
