Abstract:
The invention relates to a method for identifying a dangerous situation, wherein the dangerous situation exists for a vehicle (104) and/or emanates from the vehicle (104), wherein a plurality of measurement values are detected by means of different sensors of the vehicle (104), vehicle-to-X messages are detected by means of vehicle-to-X communication means of the vehicle (104), and data contents of the vehicle-to-X messages and the measurement values describe a situation of the surroundings of the vehicle (104) and/or a vehicle state. The method is characterized in that a defined dangerous situation is identified when the measurement values and/or the data contents of the dangerous situation meet associated criteria. The invention further relates to a corresponding system and a use of the system.
Abstract:
The invention relates to a method for determining a reference position (61) as a basis for a correction (46) of a GNSS position (12) of a vehicle (2), which GNSS position is located by means of a global satellite navigation system (15) called GNSS, the GNSS position containing an absolute position (76) of the vehicle (2), comprising: sensing the absolute position (76) of the vehicle (2) by means of the GNSS (15) when an output signal (20, 28, 34) from a motion recording sensor (18, 26, 32) of the vehicle (2) has a characteristic progression (60); determining the reference position (61) on the basis of the sensed absolute position (76); and associating the reference position (61) with the characteristic progression (60) of the output signal (20, 28, 34).
Abstract:
The invention relates to a method for determining a reference position (46) as the basis for a starting position (40) for an inertial navigation system (36) which is designed to determine the location of a vehicle (2) on the basis of the starting position (40) and a change (16) in the relative position of said vehicle (2), said method including the steps of: - detecting an ambient condition (52) around the vehicle (2), - determining a position (34, 18) of the vehicle (2) at the location of the detected ambient condition (52), and - assigning the determined position (34, 18) to the detected ambient condition (52) as a reference position (46).
Abstract:
The invention relates to a method for determining positional data (15) of a motor vehicle (2), comprising the steps: - determining positional data (15) at a first point in time (106) based on a first algorithm (54), vehicle dynamics data (16) describing a movement of the vehicle (2) and an absolute position (12) of the vehicle (2) being merged, and - determining the positional data (15) at a second point in time (107) based on a second algorithm (54') which is different from the first algorithm (54).
Abstract:
The invention relates to a method for relaying a data packet (43) containing at least positional data (16), said data packet being carried in a transmission signal (18) and received via a vehicular ad hoc network (1). The method comprises the following steps: filtering (47, 48) the received data packet (43) based on a predetermined filter condition (54); and relaying (42) the filtered data packet (50) to an additional receiver based on an identification (39) of whether the filtered data packet (50) should be relayed to the additional receiver.
Abstract:
The invention relates to different methods for verifying the plausibility of GNSS position signals, including a method for verifying the plausibility of position signals (112, 14f) of a global satellite navigation system (100) in a vehicle (1), said navigation system comprising at least one detection system (2) for detecting objects (64, 66, 70, 72, 67) in the surroundings of the vehicle (1) as well as a reception device (10) for receiving the position signals (112, 14f), said method involving the steps of: - having the reception device (10) receive the position signals (112, 14f), and determining the actual position of the vehicle (1) on the basis of the position signals (112, 14f); - having the detection system (2) detect at least one object (64, 66, 70, 72, 67) in the surroundings, and determining the position of the object (64, 66, 70, 72, 67); - verifying the plausibility of the position signals (112, 14f) by comparing at least one position of an object (64, 66, 70, 72, 67) with the actual position of the vehicle (1).
Abstract:
The invention relates to a method for providing a global navigation satellite system signal (54), referred to as a GNSS signal (54) in the following, for determining a position (30) of a vehicle, said method comprising the steps of: - receiving an unfiltered GNSS signal (12), - filtering the unfiltered GNSS signal (12) on the basis of an ambient condition (20) around the vehicle (2), and - emitting the filtered GNSS signal (54).
