Method and device in a motor vehicle for improved data fusion in an environment detection
The invention relates to a method for improved data fusion during environment detection in a motor vehicle (50), comprising the following steps: detecting (101) an environment (40) of the motor vehicle (50) using at least one sensor (2); recognising (102) objects (81) in measurement data (20) detected by the at least one sensor (2); fusioning (115) of the recognised objects (81) and the object positions thereof in an environment map (80), wherein a probability of existence is/will be assigned to objects (81) recorded in the environment map (80), and wherein the probability of existence of a recorded object (81) is reduced, when a free region (86, 86.1) is measured during the detection of the position of the recorded object, wherein a respective orientation attribute (60) is assigned to the objects (81) recorded in the environment map (80) and recorded in the environment map (80), and for a region in the sensor region (83.1, 83.2, 83.3) of the at least one sensor (2), in which a free region (86, 86.1) is measured, the probability of existence of an object (81) recorded in the region of the environment map (80) corresponding to the region is reduced in accordance with the assigned orientation attribute (60). The invention also relates to the associated device (1).
Classification of static and dynamic objects
A method classifies dynamic or static objects in a surrounding area with a control device. Sound echoes are generated by at least one sensor over a defined time period. The sound echoes are emitted into the surrounding area, and are detected by the at least one sensor in order to acquire measurement data. The measurement data of the at least one sensor are received by the control device. The received measurement data are recorded in a two-dimensional array. At least one echo trace is extracted from the array. A relative speed of the detected sound echoes with respect to the at least one sensor is determined using a derivative over time of the measurement data of the array. The at least one echo trace is classified based on the determined relative speed.
Method for determining potential damage to a vehicle battery and motor vehicle having a vehicle battery
A method for determining potential damage to a vehicle battery. In the method, at least one acceleration data set relating to a vertical acceleration of a motor vehicle, which includes the vehicle battery, is determined. The at least one acceleration data set is then checked for the presence of a predetermined damage criterion, which indicates the potential damage to the vehicle battery. Finally, only for the case that the damage criterion is determined in the at least one acceleration data set, a control signal for actuating an actuator device of the motor vehicle is generated.
