摘要:
A method and an apparatus for operating a radar sensor system with a number of adjacent individual sensors (3, 4, 5, 6), extensively synchronized with one another, for determining the position of a target object (15) are proposed. In one measurement cycle, the transit time of the radar signal emitted from one individual sensor and reflected by the target object to this individual sensor (3, 4, 5, 6) (direct echo (13, 14)) and to a different individual sensor (3, 4, 5, 6) (cross echo (16)) is evaluated. From the evaluation of the direct and cross echoes (13, 14, 16), at least the position of the target object (15) is determined, and a detection quality signal (Q) is ascertained, and once a predetermined amount of the detection quality signal (Q) is reached for a target object (15), a calibration is performed.
摘要:
A method for detecting misalignment in a motor vehicle sensor system, in which signals are emitted, signals reflected by a stationary object are received, and a relative angle and a relative distance or a longitudinal displacement and a transverse displacement between the detected object and a reference axis of the motor vehicle as well as a relative velocity between the detected object and the motor vehicle are determined on the basis of the signals emitted and received. A correction value is determined for the relative angle on the basis of the relative angle, the relative distance, and a velocity of the vehicle in question or on the basis of the longitudinal displacement, the transverse displacement, and the vehicle's own velocity.
摘要:
A method and a device for determining a future travel-course progression or travel-course range of a vehicle whose traveling speed is controllable as a function of a distance to preceding-traveling vehicles, the future course range being determined at least on the basis of a course progression of one preceding-traveling vehicle. Moreover, a lateral offset is determined for all detected preceding-traveling vehicles. The determined future course range is limited on the basis of detected stationary objects.
