Abstract:
Die Erfindung betrifft ein Verfahren und ein Fahrerassistenzsystem (1) zur Unterstützung des Fahrers eines Fahrzeugs (F1) beim Halten einer durch Fahrspurmarkierungen (S1, S2) begrenzten Fahrspur (Se), bei dem die Fahrspurmarkierungen (S1, S2) und die Lage des Fahrzeugs (F1) in der Fahrspur (Se) erfasst werden und bei dem beim Verlassen oder drohenden Verlassen der Fahrspur (Se) in einem ersten Schritt eine Spurverlasswarnung an den Fahrer des Fahrzeugs (F1) ausgegeben wird und in einem zweiten Schritt ein dem Spurverlassen entgegen wirkender kurskorrigierender Stelleingriff durchgeführt wird. Der Stelleingriff wird dabei nur dann durchgeführt, wenn das Verlassen der Fahrspur (Se) aufgrund der Art der beim Spurverlassen zu überfahrenden Fahrspurmarkierung (S1, S2) unzulässig ist oder wenn das Verlassen der Fahrspur aufgrund von seitlich der Fahrspur vorhandenen kollisionsgefährdenden Objekte (F2, F3, O1) gefahrlos nicht möglich ist.
Abstract:
A stability control system for road vehicles comprising a limit handling assistance controller which uses video lane detection measurements in conjunction with vehicle dynamics information, including inertial brakes and steering measurements to control vehicle EPS and VSC systems to assist the driver stabilise the vehicle and correct for any lane offset prior to and/or during of understeer, oversteer, split-µ and heavy breaking conditions, and lane changes.
Abstract:
Die Erfindung betrifft ein Verfahren zur Beeinflussung eines die Position und/oder die Orientierung eines Kraftfahrzeugs bezüglich einer Fahrspur steuernden oder regelnden Systems. Der Kern der Erfindung besteht darin, dass das System dann deaktiviert wird, wenn eine Kollisionsgefahr mit einem Hindernis auf der Fahrspur detektiert wird und dass das System nur dann aktiviert wird, wenn eine bezüglich der Fahrdynamik des Kraftfahrzeugs potentiell gefährliche Situation detektiert wird.
Abstract:
A vehicle steering system, with multiple independent systems, employing different route referencing, such as a primary system (10), referring to a physical reference line (30), or multiple discrete markers; and a secondary system (20), referring to an independent reference store (18), expressed as a sequential instruction table, configured as an emergency backup, implemented upon failure of the primary system; the system allows co-ordinated vehicle steering and braking, for adherence to a prescribe route; multiple discrete route markers (66) allow route banding (62), and multiple routes (60A, 60B).
Abstract:
A stably braking system and a method using the same control wheels on a single axle of a ground vehicle. Firstly, at least one of a wheel deceleration and an actual slip of each of the wheels is calculated. Hydraulic control commands are generated when a braking operation is performed in response to a braking indication signal and it is detected that the wheel deceleration or the actual slip is higher. The hydraulic control commands are configured to control a hydraulic braking system to adjust the wheel speed. When the ground vehicle drives in a straight line or turns with a first pose physical quantity, the hydraulic control command with a low priority is replaced by the hydraulic control command with a high priority and the hydraulic braking system is controlled to adjust the wheel speeds based on the identical hydraulic control commands.
Abstract:
A steering control system for a commercial vehicle having braking and steering systems. The braking system brakes dissymetrically side wheels of the vehicle. The steering system steers the vehicle based on a steering signal. The steering control system includes selection and control modules. The selection module switches between first and second steering modes. The first mode indicates steering of the vehicle by turning vehicle wheels. The second mode indicates steering of the vehicle by generating a braking signal for at least one wheel providing a yaw moment applied to the vehicle. The control module generates the first signal indicating a steering demand in the first mode and a second signal indicating a steering demand in the second mode. The control module provides the first signal to the steering system and the second signal to the braking system to brake the vehicle dissymetrically to steer the vehicle with the yaw moment.
Abstract:
A method for open-loop or closed-loop control of a driver assistance system of a vehicle, including: a) using a first sensor device to detect from a roadway at least one lane and a roadway marking that separates the lane from an edge of the roadway; b) using a second sensor device to detect operation of at least one operating device of the vehicle that influences the driving dynamics of the vehicle by virtue of the driver; c) using steering actuators and/or brake actuators to influence the driving dynamics of the vehicle; and d) outputting, if there is a threat of the vehicle leaving the lane, as detected by the first sensor device, a first warning signal. A related driver assistance system is also described.
