摘要： The invention relates to a method for operating a sensor arrangement (2) in a motor vehicle (1) based on a DSI protocol, wherein the sensor arrangement (2) has a central processing unit (3) as a master and a plurality of sensor units (S1, S2, S3) as slaves controlled by the master, the central processing unit (3) and the sensor units (S1, S2, S3) are connected to a bus line (4) and communication between the central processing unit (3) and the sensor units (S1, S2, S3) takes place via the bus line (4), characterized by the following method steps: sending a first message from the central processing unit (3) to a first sensor (S1) and subsequently sending a second message from the central processing unit (3) to a second sensor (S2) without the central processing unit (3) waiting to receive a response message from the first sensor (S1). In this way, such a method for operating a sensor arrangement (2) in a motor vehicle (1) is provided in which communication between the master and the slaves is regularly possible at a high payload data rate while at the same time ensuring a predetermined ASIL level.

摘要： According to a method for assisting reverse driving of a combination (1), an actual value for a hitch angle of the combination (1) is determined by a computing unit (6) depending on sensor data generated by a hitch angle sensor. A hitch length of a trailer (3), given by a distance between a trailer body (11) and a hitch (7) of a vehicle (2), is determined depending on environmental sensor data of the combination (1). A collision value for the hitch angle is determined by the computing unit (6) depending on the hitch length, and the safety measure is triggered by the computing unit (6) depending on the actual value and the collision value for the hitch angle.

摘要： The invention relates to a position capturing device (60) for a light signal redirection device (34, 40) of an optical measurement apparatus (12) for capturing objects (18) in a monitoring region (16), to a light signal redirection device (34, 40), to an optical measurement apparatus (12) and to a method for operating a position capturing device (60). The position capturing device (60) is designed for providing at least one position signal (68) corresponding to a deflection (72) of at least one redirection region (42a, 42b) of the light signal redirection device (34, 40). The at least one redirection region (42a, 42b) is used to redirect at least one light signal (20, 22) and is rotatable at least in a partially circumferential manner with respect to at least one pivot (46) in at least one direction of rotation (48). The position capturing device (60) has at least one position region (62), which is mechanically coupled to the at least one redirection region (42a, 42b) of the light signal redirection device (34, 40) in a manner such that the at least one position region (62) can rotate jointly with the at least one redirection region (42a, 42b). The at least one position region (62) is designed to provide at least one position signal (68) corresponding to a deflection (72) of the at least one redirection region (42a, 42b). The at least one position region (62) has at least one diffractive structure (63), which is designed such that light signals (20) can be shaped to form position light signals (68) depending on their incidence (52, 53) on the at least one position region (62).

摘要： A method for determining a distance of an object with the aid of an optical detection apparatus and such an apparatus are described. A light signal pulse is emitted and reflected at the object, and is received as an echo light signal pulse. The echo light signal pulse is divided upon reception into temporally successive discrete reception time windows and converted into corresponding electrical energy. The end of the respective conversion is in each case assigned as the sampling time to the corresponding time window. The electrical energies of the time windows are compared in each case with a threshold value. As soon as the electrical energy of a first reference reception time window is greater than the threshold value, a linear interpolation of the temporal profile of the discrete electrical reception signal is carried out temporally before the sampling time of the first reference time window.

摘要： Techniques are described for compressing image data for transmission to a computer system of a remote operator controlling a vehicle. A visual representation of a surrounding environment is generated from one or more images captured at the vehicle. One or more regions of interest in the visual representation are identified based at least on information received from the computer system of the remote operator, the information indicating a direction or area of focus of the remote operator. Regions of interest can be compressed to a lesser extent than regions located outside the regions of interest. The compressed visual representation is transmitted to the computer system for decompression and, ultimately, display on one or more display devices viewed by the remote operator.
