    摘要: In a method and a device for determining the position of an object in relation to a vehicle, for use in a driver assistance system of the vehicle, a first ultrasound pulse is transmitted by an ultrasound sensor situated on the vehicle, the ultrasound pulse including multiple predefined transmission frequencies which result in a variation of the directional characteristic of the ultrasound sensor. The transmitted first ultrasound pulse is reflected on the object and is received again as a first echo pulse. A frequency spectrum of the first echo pulse is subsequently determined, and a first absolute value of a relative offset angle of the object is determined as a function of the frequency spectrum of the first echo pulse and the directional characteristics.

    摘要: A vehicle operation assist system includes as assist yaw rate calculator which calculates a necessary moving amount to avoid an obstacle based on a detection result of the obstacle by a radar device, and a vehicle movement controller controls lateral movement of the vehicle based on the calculated moving amount. When an avoiding operation detector determines initiation of an obstacle avoiding operation by the driver, the vehicle movement controller operates a braking device to control the lateral movement of the vehicle, so that the obstacle can be reliably avoided. When a restoring operation detector determines initiation of a restoring operation, the vehicle movement controller operates a power steering device to control the lateral movement of the vehicle, so that delay in the steering operation by the driver, and excessive restoring operation of the steering handle to compensate for the delay are suppressed, thus stabilizing vehicle behavior.

    摘要: The apparatus includes transmitter-receiver units (10, 20) for emitting acoustic signals in the form of beams (F1, F2) directed rearwardly of the stern and for receiving acoustic signals reflected by the fixed structure (B, C). The number of transmitter-receivers and the beam angles of the respective beams are determined so as to include substantially the entire area behind the stern in their field of view. Each transmitter-receiver includes a transducer for converting input electrical signals into output acoustic signals and for converting reflected acoustic signals into output electrical signals which are supplied to an electronic processor unit.On the basis of electrical input and output signals, the processor unit determines the instantaneous distance between the vessel and the fixed structure. A visual and/or acoustic signalling device is connected to the processor unit for emitting a visual and/or acoustic signal in real time indicating the instantaneous distance determined.

    摘要: The adaptive system and method for ultrasound sensing comprises re-evaluating over time the detection threshold for predetermined sensing positions along the scanning direction to cope for the static target and environment changes at the sensing positions. The method includes comparing the measured echo value at each sensing position to a reference echo value corresponding to the same sensing position, and to iteratively determine a new reference value whenever the echo value is greater than the reference echo value and that the difference between the measured echo value and the reference echo value is lower than a detection assurance factor. The use of the adaptive ultrasound sensing system and method allows locating the sensor at different location without requiring a new calibration thereof, since the sensor learns the clutter dynamically and the detection thresholds are being built accordingly without being dependent on the environment in which the sensor is located.
