摘要:
A device is for determining a corrected offset value which represents the offset of the output signal of a first vehicle sensor, the sensor determining at least one motion of a vehicle. In this device, a first arrangement is provided by which at least two offset values representing the offset of the sensor are determined by at least two different methods. In addition, for at least one of the offset values of the sensor thus determined, an error band is determined in addition to the offset value. The corrected offset value is determined as a function of the offset values determined and at least one of the error bands.

A device and a method determine an offset value which represents the offset of the output signal of a vehicle sensor, the sensor detecting at least one motion of a vehicle, and the output signal is analyzed at at least two different points in time. An additional signal is determined independently of the output signal, this signal also representing the motion of the vehicle. An arrangement is provided for analyzing the characteristic of the output signal, which depends on the longitudinal velocity of the vehicle, and the characteristic of the additional signal, which also depends on the longitudinal velocity of the vehicle, in order to determine the offset value.
摘要:
A method is for determining the offset value of the output signal of a vehicle sensor. The values of the output signal of the vehicle sensor are determined. The value range of the output signal of the vehicle sensor is divided into at least two partial ranges (intervals, classes). The values of the output signal are allocated to the partial ranges. The number of number quantities representing the values of the output signal allocated to the partial ranges is determined. The number quantities are determined by at least one low-pass filter.

A method for travel course prediction in a motor vehicle having a position finding system for objects situated ahead of the vehicle is provided. In accordance with the method, a function describing the shape of the roadside is calculated on the basis of measured distance data and angle data for stationary roadside targets, wherein multiple stationary targets are identified and tracked. The path of the road is estimated for various subsets of the set of tracked stationary targets, under the assumption that these stationary targets are situated along the roadside, and roadside targets are differentiated from interfering objects on the basis of the plausibility of the resulting possible shapes of the roadside, the most probable shape of the roadside being determined on the basis of the roadside targets.

摘要:
A method for selecting the operating state of a cruise control system for motor vehicles having a distance sensor and automatic blindness detection, in which at least one additional condition is checked for automatic shutdown of the cruise control when blindness of the distance sensor is detected, and a shutdown is performed only when this additional condition is also met.
摘要:
A method of detecting a lane change of a subject vehicle (20), having a locating device (10) which uses angular resolution for locating vehicles (VEH1, VEH2, VEH3) traveling in front, and a device (44) for determining the yaw rate (ω0) of the subject vehicle. The angular velocity (ωi) of at least one vehicle traveling in front relative to the subject vehicle (20) is measured using the locating device (10), and a lane change signal (LC) indicating the lane change is formed by comparing the measured angular velocity (ωi) to the yaw rate (ω0) of the subject vehicle.
摘要:
A device and a method are for monitoring misalignment of a distance sensor on a vehicle which represents a combination of two individual procedures. The two individual procedures are selected in such a way that one procedure has advantages in areas in which the other procedure functions disadvantageously, so that the weaknesses of one procedure may be compensated for by the strengths of the other procedure. Furthermore, with the aid of this combination, it may be decided with far greater certainty whether a misalignment is present which may be removed using suitable correcting measures, or whether an extreme misalignment is present, based on which the system must be switched off.
摘要:
A method for controlling the speed of a vehicle is proposed, where, in the vehicle to be controlled, the yaw rate or rotation rate is measured, in particular to determine the curvature of the vehicle's own travel trajectory, and where, using a proximity sensor or position sensor, at least one vehicle traveling ahead or at least some other object within a sensor's sensing range is detected, particularly with regard to an offset from the travel course of the vehicle to be controlled. By delaying the travel-course offset of a vehicle driving ahead, determined in preset measuring cycles, by a predefined time span, and by using the then instantaneous curvature of the travel trajectory, a historical travel-course offset is ascertained, one is able to simply and rapidly predict the travel course of the vehicle to be controlled.
摘要:
A method for evaluating objects in the path of a vehicle, in which a sensor is used to detect the distance (dzo, dzi) and/or the speed of the target objects (Zo, Zi). In the presence of more than one target object (Zo, Zi), only the target object (Zi) that is in an area limited by at least one parameter defined by the position relative to the vehicle (F), is included in the evaluation as a new target object (Zo), instead of the current one. The following parameters can be included as conditions for selecting a new target object: dzi≦MAX (dmin, dzo+d0, &agr;*dzo).
