Definitions

  • the invention relates to a method for evacuation of a vehicle according to the preamble of claim 1 .
  • the invention relates to a system for evacuation of a vehicle.
  • the invention relates also to a vehicle.
  • the invention also relates to a computer programme and a computer programme product.
  • One object of the present invention is to propose a method for evacuation of a vehicle which improves passenger safety.
  • a further object of the present invention is to propose a system for evacuation of a vehicle which improves passenger safety.
  • the objects are achieved with a method for evacuation of a vehicle, comprising the step of determining an emergency situation which calls for evacuation of a vehicle, and further comprising the step, when such an emergency situation is determined, of automatically adapting the vehicle for evacuation by ensuring the activation of cabin interior lighting and the activation of available escape routes.
  • a method for evacuation of a vehicle comprising the step of determining an emergency situation which calls for evacuation of a vehicle, and further comprising the step, when such an emergency situation is determined, of automatically adapting the vehicle for evacuation by ensuring the activation of cabin interior lighting and the activation of available escape routes.
  • This makes it easier for passengers to quickly make their way out of the bus, thus improving passenger safety. It also obviates any emergency door opening devices, since the doors will open automatically to provide escape routes for evacuation.
  • Available escape routes also comprise alternative escape routes in case the vehicle's doors are for any reason not available as escape routes, thereby further improving passenger safety.
  • Alternative escape routes may comprise windows which, upon activation, become accessible so that they open or are easy
  • the method further comprises the step, when such an emergency situation is determined, of also ensuring the activation of external lighting of the vehicle. Passengers are thus provided with good visibility during their actual escape and when outside the vehicle to facilitate evacuation and improve safety during the exit process and enable evacuated persons to see where they are going in the dark, but also enable other road users to see them. Activation of the external lighting thus further improves passenger safety.
  • the method further comprises the step, when such an emergency situation is determined, of activating warning signalling.
  • Such signalling improves safety for the surroundings and passengers by drawing their attention to the emergency situation.
  • the signalling may be visual, e.g. by flashing, and/or acoustic, e.g. by signal horn.
  • the method further comprises the step, where necessary in such an emergency situation, of activating backup systems for ensuring the activation of cabin interior lighting and the activation of available escape routes. Passenger safety is thus further improved.
  • the step, when such an emergency situation is determined, of automatically adapting the vehicle for evacuation comprises, where necessary, activating an automatic emergency stop process. Passenger safety is thus improved in that the vehicle is automatically and safely brought to a halt, e.g. in cases where the driver becomes ill such as to be unable to operate the vehicle. Improved safety is also made possible in that before the emergency stop process the driver can focus on it being safe to come to a halt by checking that there are no persons or other obstacles in the vehicle's path, and can take other measures before evacuation.
  • the method comprises the step of controlling the emergency stop process while catering for a passenger perspective which takes passenger safety considerations into account. Passenger safety is thus improved.
  • the method further comprises the step of determining passenger distribution and passenger positions in the vehicle, as a basis for controlling the emergency stop process.
  • passenger distribution such as where in the vehicle, e.g. a bus, the passengers are, and of passenger positions in terms of whether a passenger is standing, sitting, sitting in a wheelchair, lying in a pram or the like, makes it possible for the operation of the vehicle to be adapted automatically to passenger positions, thereby improving passenger safety and also passenger comfort.

Description

METHOD AND SYSTEM FOR EVACUATION OF A VEHICLE
TECHNICAL FIELD
The invention relates to a method for evacuation of a vehicle according to the preamble of claim 1 . The invention relates to a system for evacuation of a vehicle. The invention relates also to a vehicle. The invention also relates to a computer programme and a computer programme product.
BACKGROUND
There are various scenarios in which passengers, e.g. on board a bus, may need to be evacuated quickly. The driver may for example become ill such as to be unable to operate the vehicle, potentially leading to situations which may require evacuation, or the bus may catch fire or suffer an accident requiring rapid evacuation.
If any of the scenarios mentioned above occurs when it is dark inside and/or outside the bus and evacuation of the passengers is called for, problems and, in the worst case, injuries may occur, potentially making it difficult for passengers to quickly make their way out of the bus. It may for example be difficult to find emergency opening devices for the doors and also to understand how they work in such a panic situation. OBJECTS OF THE INVENTION
One object of the present invention is to propose a method for evacuation of a vehicle which improves passenger safety.
A further object of the present invention is to propose a system for evacuation of a vehicle which improves passenger safety.
SUMMARY OF THE INVENTION These and other objects indicated by the description set out below are achieved by a method, a system and a vehicle of the kinds indicated in the introduction which further present the features indicated in the characterising part of the attached independent claim 1 . Preferred embodiments of the method and the system are defined in the attached dependent claims.
According to the invention the objects are achieved with a method for evacuation of a vehicle, comprising the step of determining an emergency situation which calls for evacuation of a vehicle, and further comprising the step, when such an emergency situation is determined, of automatically adapting the vehicle for evacuation by ensuring the activation of cabin interior lighting and the activation of available escape routes. This makes it easier for passengers to quickly make their way out of the bus, thus improving passenger safety. It also obviates any emergency door opening devices, since the doors will open automatically to provide escape routes for evacuation. Available escape routes also comprise alternative escape routes in case the vehicle's doors are for any reason not available as escape routes, thereby further improving passenger safety. Alternative escape routes may comprise windows which, upon activation, become accessible so that they open or are easy for passengers to open for evacuation of the vehicle. Alternative escape routes may comprise roof hatches which, upon activation, become accessible so that they open or are easy for passengers to open for evacuation of the vehicle.
In one embodiment the method further comprises the step, when such an emergency situation is determined, of also ensuring the activation of external lighting of the vehicle. Passengers are thus provided with good visibility during their actual escape and when outside the vehicle to facilitate evacuation and improve safety during the exit process and enable evacuated persons to see where they are going in the dark, but also enable other road users to see them. Activation of the external lighting thus further improves passenger safety. In one embodiment the method further comprises the step, when such an emergency situation is determined, of activating warning signalling. Such signalling improves safety for the surroundings and passengers by drawing their attention to the emergency situation. The signalling may be visual, e.g. by flashing, and/or acoustic, e.g. by signal horn.
In one embodiment the method further comprises the step, where necessary in such an emergency situation, of activating backup systems for ensuring the activation of cabin interior lighting and the activation of available escape routes. Passenger safety is thus further improved. In one embodiment of the method the step, when such an emergency situation is determined, of automatically adapting the vehicle for evacuation comprises, where necessary, activating an automatic emergency stop process. Passenger safety is thus improved in that the vehicle is automatically and safely brought to a halt, e.g. in cases where the driver becomes ill such as to be unable to operate the vehicle. Improved safety is also made possible in that before the emergency stop process the driver can focus on it being safe to come to a halt by checking that there are no persons or other obstacles in the vehicle's path, and can take other measures before evacuation. In one embodiment the method comprises the step of controlling the emergency stop process while catering for a passenger perspective which takes passenger safety considerations into account. Passenger safety is thus improved.
In one embodiment the method further comprises the step of determining passenger distribution and passenger positions in the vehicle, as a basis for controlling the emergency stop process. Taking account of passenger distribution such as where in the vehicle, e.g. a bus, the passengers are, and of passenger positions in terms of whether a passenger is standing, sitting, sitting in a wheelchair, lying in a pram or the like, makes it possible for the operation of the vehicle to be adapted automatically to passenger positions, thereby improving passenger safety and also passenger comfort.
According to the invention the objects are achieved with a system for evacuation of a vehicle, comprising means for determining an emergency situation which calls for evacuation of a vehicle, and further comprising means, when such an emergency situation is determined, for automatically adapting the vehicle for evacuation by ensuring the activation of cabin interior lighting and the activation of available escape routes.
In one embodiment the system further comprises means, when such an emergency situation is determined, for also ensuring the activation of external lighting of the vehicle.
In one embodiment the system further comprises means, when such an emergency situation is determined, for activating warning signalling.
In one embodiment the system further comprises means, where necessary in such an emergency situation, for activating backup systems for ensuring the activation of cabin interior lighting and the activation of available escape routes.
In one embodiment of the system comprises means, when such an emergency situation is determined, for automatically adapting the vehicle for evacuation comprises means for activating, where necessary, an automatic emergency stop process.
In one embodiment the system comprises means for controlling the emergency stop process while catering for a passenger perspective which takes passenger safety considerations into account. In one embodiment the system further comprises means for determining passenger distribution and passenger positions in the vehicle, as a basis for controlling the emergency stop process. The system claims indicate advantages corresponding to those mentioned above for the respective method claims.
