Abstract
A method for an emergency call from a vehicle to an alarm centre, including receiving a wireless initiation signal from a portable alarm unit, evaluating the initiation signal, and sending, based on the result of the evaluation, a wireless alarm signal from a vehicle communication system arranged in the vehicle to the alarm centre. If the owner of the vehicle or some other person gets into an emergency, for instance is assaulted, in the immediate surroundings of the vehicle, it is thus possible to send an alarm signal to an alarm centre via the vehicle without first entering it. The personal safety for the individual is therefore increased. In addition, in the case of an assault, the perpetrator can be frightened away by sound and/or light signals emitted by the vehicle.
