Embodiment Construction
[0096] figure 1 A schematic side view of a fleet 1 of vehicles loosely coupled to one another is shown according to a preferred embodiment. The convoy 1 includes a leader vehicle 2 as the foremost vehicle and further vehicles, a second vehicle 4 , a third vehicle 6 , a fourth vehicle 8 and a fifth vehicle 12 as well as the sixth and last vehicle 12 . Instead of the six vehicles shown, fleet 1 can also comprise more or fewer vehicles. figure 2 A side view of convoy 1 is shown as it travels along a left-hand curve of the route traveled by the convoy. The six motor vehicles 2 to 12 each represent a participant in the convoy 10 . It is assumed here that the convoy 10 has been formed, that is to say completed: the motor vehicles 2 to 12 agree with one another that they can all form the convoy 1 .
[0097] In the exemplary embodiment, the motor vehicles 2 to 12 are heavy-duty commercial vehicles, which each have an electrically controllable drive motor, which is embodied here, ...

The invention relates to a method for the open-loop or closed-loop control of the driving and braking behavior of a leading first vehicle (2) of a vehicle train (1), which is or should be loosely coupled and is composed of the leading first motor vehicle (2) and at least one second motor vehicle (4, 6, 8, 10, 12), during a trip of the vehicle train (1). The first motor vehicle (2) leading the vehicle train (1) and the at least one second motor vehicle (4, 6, 8, 10, 12) each form a participant of the vehicle train (1). The invention is characterized in that, already before the start of the tripof the vehicle train (1), participant data characterizing a driving and braking behavior of the participant (2, 4, 6, 8, 10, 12) in question existing at a time point preceding the start of the trip are determined or obtained by each participant (2, 4, 6, 8, 10, 12) of the vehicle train (1) itself and are transferred from each participant (2, 4, 6, 8, 10, 12) different from the leading first motorvehicle (2) to the leading first motor vehicle (2), and / or are obtained by the leading first motor vehicle (2) from infrastructure (X) that is external to the vehicle train (1) and that has previously received from all participants (2, 4, 6, 8, 10, 12) the participant data determined or obtained by all participants (2, 4, 6, 8, 10, 12) themselves.
Description
technical field [0001] The invention relates to a method according to the preamble of claim 1 for the control or regulation of a lead first vehicle of a loosely coupled or to-be-loosely coupled convoy consisting of a lead first motor vehicle and at least one second motor vehicle. A method of driving behavior during fleet driving. Background technique [0002] This loosely coupled fleet includes at least a first and last motor vehicle, and possibly intermediate vehicles. It is therefore known that motor vehicles are driven electronically, distance control and lateral control as closely as possible in succession. In this case, the respective following motor vehicle is oriented optically in front of the motor vehicle. All motor vehicles are equipped with sensors for blind spot monitoring and rear area monitoring and sensors for road orientation, as well as at least means for vehicle-to-vehicle communication. Such loosely coupled convoys or vehicle trains of motor vehicles ar...
