Embodiment Construction

[0044] exist figure 1 A schematic plan view of a traffic node 1 is shown in , in order to illustrate the method 2 according to one embodiment. By way of example, the traffic node 1 is designed as an unclear traffic area of ​​a T-junction.

[0045] The first vehicle 4 follows the second vehicle 6 . The first vehicle 4 is designed, for example, as a vehicle that can be operated autonomously according to the BASt definition and is in a fully automated operating mode.

[0046] The first vehicle 4 has a control unit 8 which receives and evaluates the measurement data of the surroundings sensor system 10 . Here, the surroundings sensor device 10 is used in a simplified manner for one or more sensor units, which can have, for example, camera sensors, LIDAR sensors, radar sensors, GNSS sensors or the like.

[0047] The control device 8 is connected to a machine-readable storage medium 12 , on which one or more computer programs are stored, which can be executed by the control devic...

Abstract

The invention discloses a method for adjusting a safety distance between a first vehicle and a second vehicle preceding the first vehicle by at least one control device, in particular to a method foradjusting a safety distance between a first vehicle and a second vehicle preceding the first vehicle at a bunched traffic site by at least one control device, which includes receiving measurement dataof at least one sensor unit with the at least one control device; analyzing the measurement data of the at least one sensor unit to determine a bunched traffic site in front of the second vehicle anddetermining a safety distance of the first vehicle from the second vehicle in the event that a traffic node is detected in front and introudcing an adherence to the determined safety distance by thecontrol device, said adherence to the safety distance of the first vehicle from the second vehicle being used for possible receding of the second vehicle. A control device, a computer program and a machine-readable storage medium are further disclosed.

Description

technical field [0001] The invention relates to a method for adjusting the distance between a first vehicle and a second vehicle driving in front of the first vehicle, in particular at a traffic junction. The method of spacing between two vehicles. The invention also relates to a control device, a computer program and a machine-readable storage medium. Background technique [0002] Various methods are already known for the automated operation of vehicles. In particular, in the case of this method, the longitudinal and transverse guidance of the vehicle is controlled in such a way that the speed is optimally adjusted to the distance from the preceding vehicle. Depending on defined comfort conditions, traffic signs, lane markings and light signals, the safety distance of the vehicle to vehicles driving ahead can be adjusted. [0003] At traffic nodes, such as intersections or road exits, there may be only a limited overview of traffic events. For example, a stopped vehicle...
