A crop row detection system of the present invention includes: a sensor that outputs sensor data including position information of an object; and a processing device that detects adjacent crop rows based on the sensor data. The processing device executes: creating a map of crop rows in a vehicle coordinate system based on the sensor data; using the map to start an object detection search parallel to a second coordinate axis from a first coordinate point in the vehicle coordinate system to detect a left row and a right row of the adjacent crop rows. The processing device is configured to, when updating the first coordinate point, increase or decrease the first coordinate on the first coordinate axis of the first coordinate point, and align a second coordinate on the second coordinate axis of the first coordinate point with a second coordinate on the second coordinate axis of a crop row center point, where distances to the left row and the right row of the adjacent crop rows are equal.

An object of the present invention is to flexibly collect vehicle data before and after a vehicle data collection condition is satisfied while suppressing communication constraints and cost increases. A vehicle data collection device 5 includes a setting unit 40 which determines a collection setting that is setting information for each ECU corresponding to a collection request; a collection condition determination unit 51 which sets a collection condition based on the collection setting, and determines whether the collection condition is satisfied; a collected data output unit 52 which sets collected data based on the collection setting, and acquires the collected data from each ECU; a multi-stage holding unit 53 which holds collected data output before the collection condition is satisfied and collected data output after the collection condition is satisfied based on the collection setting; a transmission standby unit 60 which keeps the held collected data in a standby state for transmission; and a transmission unit 31 which transmits the collected data kept in the standby state by the transmission standby unit 60 to a request source. The collection request includes a set value related to the number of pieces of collected data held in a multi-stage holding unit 53. The setting unit 40 determines the collection setting by changing the number of pieces of collected data held in the multi-stage holding unit 53 from the set value.

Die Erfindung betrifft ein Kastenprofil 1 für ein Fahrzeugrückhaltesystem, ein Fahrzeugrückhaltesystem mit einem solchen Kastenprofil 1 und ein Verfahren zur Herstellung eines Kastenprofils 1. Ein Kastenprofil 1 weist einen im Querschnitt U-förmigen Kastenkörper 3 mit einem verjüngten Endabschnitt 5 auf. Die Verjüngung des Endabschnitts 5 ist durch eine, den Querschnitt des Endabschnitts 5 verringernde Sicke 12 erzeugt. Der Endabschnitt 5 wird durch das Einformen und die Ausbildung der Sicke 12 so verjüngt und im Querschnitt verringert, dass der verjüngte Endabschnitt 5 in einem nicht verjüngten Endabschnitt 6 eines weiteren Kastenprofils 1 formschlüssig aufnehmbar ist. Mehrere Kastenprofile 1 werden in einem Fahrzeugrückhaltesystem schussweise aneinandergesetzt.

The invention provides a method for identifying a vehicle and a system for carrying out the method, which can be used to check the identity of the vehicle quickly and reliably. This is achieved by virtue of a multiplicity of RFID transponders, but at least one RFID transponder on which data about the vehicle to be identified and/or the vehicle keeper are stored, and/or an RFID transponder that identifies a part of the same vehicle and at least one further RFID transponder mounted on the same vehicle being read by at least one RFID reader. The data thus read from all the RFID transponders of the same vehicle are stored in a central or local data memory (11), specifically together with the location and the time at which the data were read. The dataset that has been read is then analysed by an analysis device (10). The one dataset that has been read is rated with a Q factor by the analysis device (10).

La présente invention concerne un procédé pour la détermination d'un débit de véhicules sur un brin routier d'un réseau routier. On construit un modèle pour déterminer un débit de véhicules sur un brin routier de la manière suivante: pour chaque brin routier d'un réseau routier d'apprentissage, on détermine une séquence ordonnée selon un sens de circulation comprenant des descripteurs statiques du brin routier d'apprentissage et de ces voisins ; on entraine un réseau de neurones à mémoire court et long terme sur les séquences ordonnées et on concatène le résultat avec des descripteurs dynamiques des brins routiers d'apprentissage ; on entraine un réseau de neurones transformeur sur ces concaténations. Puis on détermine le débit de véhicules sur un brin routier d'un réseau routier d'intérêt en appliquant le modèle construit à des descripteurs statiques et dynamiques du brin routier et à des descripteurs statiques des brins routiers voisins.
