摘要:
The invention regards a method for computationally predicting future movement behavior of a target object and program comprising the steps of producing sensor data by at least one sensor physically sensing the environment of a host vehicle, computing a plurality of movement behavior alternatives of the target object sensed by the sensors, by predicting movement behaviors of the target object applying a context based prediction step using at least one indirect indicator and/or indicator combinations derived from sensor data, wherein in said context based prediction step a probability that the target object will execute a movement behavior at a time is estimated. A future position of the target object is estimated and a signal representing the estimated future position is outputted. In the context based prediction step at least one history indicator for at least one movement behavior alternative is generated for a current point in time using at least one indicator value of an indirect indicator at a point in time in the past.

The invention relates to a method for controlling the speed of a vehicle. According to the invention, the future traffic situation is predicted according to the acceleration of the controlled vehicle and is evaluated by means of a cost function which is defined in such a manner that the value thereof increases according to the number of relevant vehicles which drive in front of the controlled vehicle, and according to the relevance thereof. Subsequently, the value of said acceleration, wherein the cost function assumes the minimal value, is determined as an acceleration setpoint value and the acceleration of the vehicle is set to said value. The novel method increases the safety and comfort of the driver.

The invention relates to a system for automatic following-distance control, notably in congested traffic, in a motor vehicle (1) so as to facilitate driving in congested traffic by both taking over transverse steering by means of an automatic steering system and ensuring that a given distance is maintained to a vehicle driving ahead. The latter function calls for an adaptive driving and brake control system with a 'stop' and 'go' function. According to the invention selection and decision means (5, 6, 7, 8, 9) are provided for which are able to selected both control parameters and control types, for example following-distance control of the motor vehicle (1) in accordance with road markings recognized by video camera or in accordance with a detected leading vehicle. The system is divided into hierarchical levels (I-IV). The driver always remains in the monitoring and adaptation circuit assigned to the highest hierarchical level (IV) so that he has the highest priority and can overrule the system at any time.

Disclosed is an arrangement (1) and a method for mitigating a forward collision between a host vehicle (2a), having sensors (3) for monitoring a road ahead and wheel brakes (6, 7), and an oncoming vehicle (2b). The sensors (3) are utilized to estimate parameters of an oncoming vehicle (2b), such as the distance between the vehicles (2), lateral and longitudinal velocity and acceleration of the oncoming vehicle (2b), and relative longitudinal velocity between vehicles (2). The estimated parameters are utilized to predict a future path of the oncoming vehicle (2b), and host vehicle (2a) parameters to predict a future path thereof. The predicted future paths are assessed to determine if a forward collision is likely unavoidable assuming full freedom for performing avoidance manoeuvres for both vehicles (2). The wheel brakes (6, 7) are controlled to reduce a relative longitudinal velocity between the vehicles (2) at a predicted collision instant if determined that a forward collision is likely unavoidable at a determined relative longitudinal velocity above a first threshold.

摘要:
An adaptive cruise control system (100) for a host vehicle (260) includes a sensor (120) and a controller (105). The sensor (120) is configured to detect a vehicle (255) in front of the host vehicle (260). The controller (105) receives an indication of the detected vehicle (255) from the sensor (120) and is configured to maintain a speed of the host vehicle (260) at a desired speed, to determine a speed of the detected vehicle (255) relative to the host vehicle (260), and adjust an acceleration rate of the host vehicle (260) based on the relative speed.

Die vorliegende Erfindung beschreibt ein Steuerungs-System, das dazu eingerichtet und bestimmt ist, vorausfahrende Kraftfahrzeuge zu erkennen. Das Steuerungs-System ist wenigstens dazu eingerichtet und bestimmt, ein am Verkehr teilnehmendes anderes Kraftfahrzeug mit dem mindestens einen Umfeldsensor zu erfassen. Das Steuerungs-System ist wenigstens dazu eingerichtet und bestimmt, Positionen des anderen Kraftfahrzeugs für ein vorbestimmtes Zeitintervall zu ermitteln. Das Steuerungs-System ist wenigstens dazu eingerichtet und bestimmt, am Ende des Zeitintervalls zu bestimmen, ob a) eine aktuelle Position des eigenen Kraftfahrzeugs vor wenigstens einer der ermittelten Positionen des anderen Kraftfahrzeugs liegt; b) ein lateraler Abstand zwischen einer jeweils nächsten Position der ermittelten Positionen des anderen Kraftfahrzeugs vor und hinter der aktuellen Position des eigenen Kraftfahrzeugs einen vorbestimmten Wert nicht überschreitet; und c) eine Anzahl der ermittelten Positionen des anderen Kraftfahrzeugs, die sich vor der aktuellen Position des eigenen Kraftfahrzeugs befinden, eine vorbestimmte Mindestanzahl überschreitet. Das Steuerungs-System ist wenigstens dazu eingerichtet und bestimmt, aus den ermittelten Positionen des anderen Kraftfahrzeugs eine Trajektorie zu estimieren, wenn bestimmt wurde, dass a), b) und c) erfüllt sind. Das Steuerungs-System ist wenigstens dazu eingerichtet und bestimmt, das andere Kraftfahrzeug auszuwählen, um diesem zu folgen, basierend auf einem Abweichungsmaß zwischen der estimierten Trajektorie des anderen Kraftfahrzeugs und einer Trajektorie des eigenen Kraftfahrzeugs.
