摘要:
A driver assistance system that includes a RADAR system, a video system, a brake control unit, and a controller, such as an engine control unit. The RADAR system is mounted on the front of the vehicle and is positioned to detect the location of various objects. The video system captures video images. The controller receives data from both the RADAR system and the video system and identifies objects and their locations based on both the RADAR and the video data. The controller then adjusts the operation of the engine and the vehicle brakes based on the identified objects and their locations. In some embodiments, the driver assistance system also includes a human-machine interface that notifies the driver when an object is identified and located.

A method of determining a safe distance (dsafe) between a first vehicle (1) and a second vehicle (2) moving ahead of the first vehicle, each vehicle having a state which comprises at least one of a position (s1, s2), a speed and an acceleration of the respective vehicle, the method comprising the steps of:—collecting sensor data relating to the state of the vehicles (1, 2),—determining, using the sensor data and a time-dependent description of the state of the second vehicle (2), a state of the second vehicle (2) as a result of a maximum deceleration of said second vehicle,—determining, using a time-dependent model of the behaviour of the first vehicle (1) and said state of the second vehicle (2), a state of the first vehicle (1) as a result of said maximum deceleration of said second vehicle (2), and—determining, using said state of the second vehicle (2) and said state of the first vehicle (1), the safe distance (dsafe). Said state of the second vehicle (2) and said state of the first vehicle (1) involve uncertainties introduced by the sensor data, thus increasing the safety margin of the method.

A vehicle communication system (10) for cloud-hosting sensor-data from a plurality of vehicles where each of the vehicles is equipped with one or more sensors used to detect objects proximate to each of the vehicles includes a transceiver (20) and a controller (26). The transceiver (20) is used to communicate sensor-data from a first-sensor (22A) on a first-vehicle (24A) and from a second-sensor (22B) on a second-vehicle (24B). The controller (26) is configured to receive, via the transceiver (20), first-data (30A) from the first-sensor (22A) and second-data (30B) from the second-sensor (22B), and determine when the first-data (30A) and the second-data (30B) are both indicative of an object (16) proximate to the first-vehicle (24A) and the second-vehicle (24B), where the first-data (30A) is characterized by a first-confidence (34A) and the second-data (30B) is characterized by a second-confidence (34B). The controller (26) is configured to prevent communication of the second-data (30B) to the first-vehicle (24A) when the first-confidence (34A) is greater than the second-confidence (34B).
摘要:
The present invention relates to a method and a system for control of a cruise control, which cruise control supplies a reference speed v ref for control of a propulsion system. The reference speed v ref is here based on a set speed v set chosen by a driver of a vehicle which is provided with the propulsion system, and it is possible for said cruise control to allow deviation between the reference speed v ref and the set speed v set . The present invention detects whether there is at least one particular driving situation, this detection being based on how the driver acts when the vehicle is in motion. If there is at least one particular driving situation, a first limitation of the permissible deviation is applied during the at least one particular driving situation. According to the invention, a second limitation of the permissible deviation is also applied during a period of time T A after the end of the at least one particular driving situation.
摘要:
Die Erfindung betrifft ein Verfahren zum Betreiben einer Steuervorrichtung (20) zum autonomen Führen eines Kraftfahrzeugs (10), wobei als eine durch die Steuervorrichtung (20) einzustellende Fahrgeschwindigkeit (14) eine Sollgeschwindigkeit (16) vorgegeben wird und durch die Steuervorrichtung (20) mittels einer Erkennungseinrichtung (11) ein langsamer als die Sollgeschwindigkeit (16) vorausfahrendes Fremdfahrzeug (17) erkannt wird, wobei ein Geschwindigkeitsunterschied (19) einer Fahrgeschwindigkeit (18) des Fremdfahrzeugs (17) zu der Sollgeschwindigkeit (16) größer als Null, aber kleiner als ein vorbestimmter Höchstwert (G0) ist. Die Erfindung sieht vor, dass in diesem Fall ein Akkumulatorwert (A) auf einen Startwert eingestellt wird und in mehreren nacheinander durchgeführten Prüfdurchläufen (27) jeweils ein aktueller Geschwindigkeitswert (G) des Geschwindigkeitsunterschieds (19) erfasst wird und in Abhängigkeit von dem Geschwindigkeitswert (G) ein Vorteilswert (V) gebildet und der Vorteilswert (V) zu dem Akkumulatorwert (A) hinzuaddiert wird und falls der Akkumulatorwert (A) ein vorbestimmtes Überholkriterium (34) erfüllt, ein Überholsignal (23) zum Freigeben eines Überholmanövers (25) erzeugt wird.
