A prediction apparatus for predicting a predicted trajectory for a safety driver assistant system for a vehicle includes a receiving unit and a determination unit. The receiving unit is configured to receive at least one sensor information from at least one vehicle sensor of the vehicle and at least one trajectory information from at least one further driver assistant system of the vehicle. The determination unit is configured to determine the predicted trajectory for the vehicle using planned the trajectory information or the sensor information.

Prediction apparatus for predicting a predicted trajectory for a safety driver assistant system for a vehicle

A method of parametrizing an environment model () for a driver assistance system () of a vehicle () comprises steps of defining, determining and transforming. In the step of defining, a reference point (R) on a predicted trajectory (T) of the vehicle () is defined in relation to a detected object (OBJ) in an environment of the vehicle (). In the step of determining, an angle (α) between a tangent (tan) to the trajectory (T) in the reference point (R) and a first axis (x) of a vehicle coordinate system (K) and a relative distance between object (OBJ) and reference point (R) are determined, to obtain object-related information (). In the step of transforming, the object-related information () is transformed according to the determined angle (α) to a new coordinate system with its first axis tangential to the trajectory (T) in the reference point (R), to obtain parametrization data ().

Method and apparatus for aggregating/representing an environment model for a driver assistance system of a vehicle

An evaluation apparatus for evaluating a predefined trajectory hypothesis for a vehicle includes a calculation unit, a detection unit and an assigning unit. The calculation unit is configured to calculate at least one necessary driving parameter for the vehicle to follow the predefined trajectory hypothesis. The detection unit is configured to detect a current driving parameter of the vehicle. The assigning unit is configured to assign a probability value for the vehicle to follow the predefined trajectory hypothesis using the current driving parameter and the necessary driving parameter.

Evaluation apparatus for evaluating a trajectory hypothesis for a vehicle

A method for controlling a warning module based on an expected time period up to a collision of a vehicle with an obstacle, including: permitting an outputting of a generated warning to a driver of the vehicle if the expected time period up to the collision is shorter than a limiting value function, which depends on a speed of the obstacle and/or a relative speed of the vehicle with respect to the obstacle, and otherwise suppressing a warning to the driver; in which the warning module is configured to generate the warning of an imminent triggering of an automatic emergency braking process of the vehicle to avoid the collision. Also described is a related device and computer readable medium.

Method and device for controlling a warning module

An apparatus for warning a vehicle driver about an object, including: a) a sensor device having a detection area (DA) extending from a front DA, in front of a vehicle, including the front DA, to a rear end of a side DA, laterally from one vehicle side and whose length corresponds to no more than the vehicle length, the sensor device detecting an object, b) a control device to evaluate the sensor signals for objects and defines a warning area (WA) that is dynamically alterable (DyA) based on the vehicle speed, the WA being alterable within the side DA between a non-zero minimum/maximum WA, c) a warning device generating a warning signal for a detected object, d) the sensor device being such that the DA continues from the side DA into a rear DA behind the vehicle rear, including the rear DA, e) the control device expanding the DyA WA.

Device for warning a vehicle driver of a vehicle about an object, and vehicle having such a device

An apparatus/vehicle for warning a driver of a vehicle or vehicle/trailer (V-VT) about a stationary object (SO): a) a sensor device having a detection area (DA) including a side DA arranged laterally from a vehicle side (VS) and extending front to rear, in the direction of a longitudinal centerline of the (V-VT), and detecting the SO within the DA; b) a control device to evaluate the sensor signals as to the SO detected within the DA and define a dynamically alterable warning area (WA) that is no more than the side DA; c) a warning device to generate a warning signal if the sensor device detects the object(s) in the WA; d) the control device, on detection of the SO within the side DA and on detection of the (V-VT) turning toward the VS on which the side DA is situated, to assign a triangular cross-section to the WA.
