DETAILED DESCRIPTION
Hereinafter the term “link” refers to a communication link which may be a
physical connector, such as an optoelectronic communication wire, or a non-
physical connector such as a wireless connection, for example a radio or
microwave link.
Hereinafter the term “mutually separated bus units” refers to bus units being
separated from each other such that there is no physical connection between
the vehicles.
Hereinafter the term “bus units being mutually wirelessly interconnected”
refers to the vehicles being interconnected via a communication link for
communication between the bus units for controlling drive of the vehicles
trailing the leading vehicle such that they follow the leading vehicle. The term
thus
communication between the bus units which is a non-physical connector, i.e.
“wireless interconnection” refers to a communication link for
a wireless connection, for example a radio or microwave link, Wi-Fi,
Bluetooth, or the like.
Hereinafter the term “predetermined route” refers to a route in the form of a
road on which the bus convoy for passenger transport is intended to travel
and make stops for allowing passengers to boarding and getting off the bus
units. The bus convoy is intended for regular traffic in e.g. cities along routes
with stops where there are many passengers entering and leaving the bus
units.
Fig. 1 schematically illustrates a bus convoy 1A for passenger transport
along a predetermined route R. The bus convoy 1A comprises two mutually
10

20
25
separated bus units 2, 3, a leading bus unit 2 and a trailing bus unit 3. Said
bus units are mutually wirelessiy interconnected. The bus units 2, 3 are
constituted by buses.
The leading bus unit 2 is interconnected with the trailing bus unit 3 via a
wireless interconnection 23.
The bus convoy 1A comprises and/or is connected to a system l, not shown
in fig. 1, for an emergency stop of a bus convoy for passenger transport
along a predetermined route, an embodiment ofthe system I being shown in
fig. 3. The system I comprises means for detecting control of the leading bus
unit and means for communicating said detected control to the trailing bus
unit 3 of the bus convoy 1. Hereby the trailing bus unit 3 will follow the
leading bus unit 2 at a start and along the predetermined route R and stop
when the leading bus unit 2 stops.
Fig. 2 schematically illustrates a bus convoy 1B for passenger transport
along a predetermined route R. The bus convoy 1B comprises three mutually
separated bus units 2, 3, 4, a leading bus unit 2, and a first trailing bus unit 3
trailing the leading bus unit 2, and a second trailing bus unit 4 trailing the
second bus unit 3. The leading bus unit 2 and the trailing bus units 3, 4 form
a vehicle train with the first trailing bus unit 3 running between the leading
bus unit 2 and the second trailing bus unit 4. Said bus units 2, 3, 4 are
mutually wirelessiy interconnected with wireless interconnections 23, 34, 24.
The bus units 2, 3, 4 are constituted by buses.
There are thus two or more bus units wirelessiy interconnected in such a way
depending on the need.
The leading bus unit 2 is interconnected with the first trailing bus unit 3 via a
wireless interconnection 23, the first trailing bus unit 3 is interconnected with
the second trailing bus unit 4 via a wireless interconnection 34 and the
trailing bus unit is interconnected with the second trailing bus unit 4 via a
wireless interconnection 24.

The bus convoy IB may also be interconnected to an external unit 200 via
wireless links 22, 32, 42 to the respective bus unit 2, 3, 4.
The bus convoy IB comprises and/or is connected to a system I, not shown
in fig. 2, for an emergency stop of the a bus convoy IB, an embodiment of
the system I being shown in fig. 3. The system I comprises means for
detecting control of the leading bus unit 2 and means for communicating said
detected control to the trailing bus units 3, 4 of the bus convoy I. Hereby the
trailing bus units 3, 4 will follow the leading bus unit 2 at a start and along the
predetermined route R and stop when the leading bus unit 2 stops.
The wireless interconnections and the external unit are according to an
embodiment comprised in the system I for an emergency stop of the bus
convoy IB for passenger transport along a predetermined route according to
fig. 3.
Fig. 2 illustrates the bus convoy IB at a stop S, which according to an
example is a stop where the bus convoy has been brought to a stop due to a
determined emergency stop situation of one of the bus units, e.g. the first
trailing bus unit 3. Thus, in this example an emergency stop of all bus units 2,
3, 4 of the bus convoy IB has been activated due to the determined
emergency stop situation of the first trailing bus unit 3, wherein all bus units
2, 3, 4 has been brought to a standstill at said stop S.
The stop S can be any suitable stop along the road on which the bus convoy
is travelling including bus stop for allowing passengers to get on and off the
bus units 2, 3, 4.
When all bus units 2, 3, 4 in this case has been brought to a standstill due to
the determined emergency stop situation of the first trailing bus unit 3, the
first trailing bus unit 3 is according to an example excluded from the bus
convoy IB and the bus convoy IB continues its travelling along the route R
by wirelessly interconnecting the leading bus unit 2 and the second trailing
bus unit 4, this being shown in fig. 2 with the bus units 2, 4 being dotted.

Alternatively, when all bus units 2, 3, 4 as in this case has been brought to a
standstill due to the determined emergency stop situation of the first trailing
bus unit 3, the emergency situation of the first trailing bus unit 3 is taken care
of such that all bus units 2, 3, 4 then can continue along the route R, this not
being shown in fig. 2.
According to another situation, not shown, only the bus unit subject to the
determined emergency stop situation has been brought to a stop due to a
determined emergency stop situation of one of the bus units, e.g. the first
trailing bus unit 3. Thus, in this example an emergency stop of only the first
trailing bus unit 3 subject to the determined emergency stop situation of the
bus convoy 1B has been activated due to the determined emergency stop
situation of the first trailing bus unit 3. ln this case the bus convoy 1B
continues its travelling along the route R without the first trailing bus unit 3 by
wirelessly interconnecting the leading bus unit 2 and the second trailing bus
unit 4, wherein thus bus unit 3 has been brought to a standstill.
ln the case where the leading bus unit 2 is subjected to an emergency stop
and is not able to continue, one of the trailing bus units 3, 4, e.g. the first
trailing bus unit 3, becomes the leading vehicle unit and continues by being
wirelessly connected to the trailing bus unit.
The bus convoy 1A, 1B in fig. 1 and 2 is according to an embodiment
arranged to be controlled by a driver. According to a variant the bus convoy
1A, 1B is arranged to be controlled by a driver in the leading bus unit 2.
According to a variant the trailing bus units 3; 3, 4 are controlled by the
leading bus unit 2. According to a variant the trailing bus units 3; 3, 4 are
autonomous and do not have a driver. According to a variant one or more of
the trailing bus units have an operator/driver supervising the drive of the
trailing vehicle.

4.
Here the trailing bus unit 3 of the bus convoy 1 is subject to an emergency
stop situation. The bus units 2, 3, 4 communicate via wireless links with each
other as described below. First a means 110 for determining the emergency
10
15
20
25
23
stop situation is activated. The means 110 determines the emergency stop
situation of the trailing bus unit 3. Based upon the determined emergency
stop situation a stop of all bus units of the bus convoy is activated by means
122 or only the bus unit subject to the determined emergency stop situation
by means 124.
The means 110 thus transmits messages via messages L4, L5 the
determined emergency stop situation informing all other bus units. ln
response to the received messages L4 and L5 the other buses 2 and 4 stops.
A means 180 in the leading bus 2 is adapted to determine to continue without
the bus 3 subject to the emergency stop. ln response to this determination by
the means 180, means 170 are activated to reorganizing the bus convoy
based on the information that a bus in the convoy (in this case bus 3) is no
longer to be part of the bus convoy. The new bus convoy organization is the
sent to the other buses 3;4 in messages L9, L10.
Hereby a new organization in the form of a new bus convoy is formed with
the remaining bus units 2, 4. When the bus units 2, 3, 4 have reorganized to
the new bus convoy with only bus units 2 and 4 forming a new organization a
means 190 for starting the reorganized bus convoy generates a message L9
transmitted to start the new bus convoy. The message L9 needs only be sent
to the buses forming the new bus convoy, in this case bus 4. The new bus
convoy with the remaining bus units 2, 4 being mutually interconnected may
then re-start and continue the drive along its route.
ln case the leading bus 2 is subject to an emergency stop. The capabilities of
the leading bus can be transferred to one of the trailing buses. One of the
trailing buses can then assume the responsibility as a new leading bus and
re-organize the bus-convoy for further travel along the route of the bus
convoy.
