    Preferred embodiments are described in the dependent claims and in the detailed description.
    Brief description of the accompanying figures The invention will be described below with reference to the accompanying figures, of which: Figure 1 schematically illustrates a safety system according to an embodiment of the invention.
    Figure 2 illustrates a flow chart according to the method according to an embodiment of the invention.
    Detailed description of preferred embodiments of the invention The control system will now be described in more detail with reference to Figure 1. The control system is connected to one or more applications (App 1, App 2 ...) via a communication system. According to one embodiment, the communication system comprises a body control unit (BWS) which in turn is connected to said applications via cable or via wireless communication. According to this embodiment, the body control unit is adapted to control said application. The control system further comprises at least one activation unit which is adapted to generate an activation signal for activating an application. The activation unit may, for example, comprise a switch in the vehicle's instrument panel or on the application. The control system can also comprise a number of activation units that emit activation signals to activate various applications.
    The control system also comprises a coordination unit which is adapted to receive said activation signal and thereby activate a control function which comprises predetermined control rules for the vehicle. The coordination unit is further adapted to generate and transmit at least one control signal to one or more control units in the vehicle in dependence on said predetermined control rules, the vehicle being automatically regulated according to said at least one control signal. Thus, the vehicle will be automatically regulated when an application is activated. The vehicle thus gets a form of autopilot when an application is activated. The driver does not have to concentrate on both regulating the vehicle and handling the application, but can focus on only handling the application. If the vehicle is equipped with a body control unit, then the coordination unit is preferably connected to said body control unit.
    In order for the different units to be able to communicate with each other, a CAN (Controller Area Network) is used according to one embodiment. CAN denotes a serial bus system, specially developed for use in vehicles. The CAN data bus provides the opportunity for digital data exchange between sensors, control components, actuators, controllers, etc. and ensures that several controllers can access the signals from a certain sensor, to use these to control their connected components. However, other communication methods are also possible, such as FlexRay, LLN (Local Interconnect Network) or WLAN (Wireless Local Area Network).
    According to one embodiment, said control rules comprise rules for regulating the speed and / or direction of the vehicle. According to one embodiment, the control rules comprise rules for when an activation signal is received in the coordinating unit instructing the coordinating unit to generate control signals which are adapted to activate a cruise control in the vehicle at the current speed of the vehicle as setpoint. The control signals are then sent to a cruise control, which will steer the vehicle so that it automatically maintains the current speed.
    In order to automatically regulate the speed and / or direction of the vehicle, according to one embodiment, sensing means adapted to sense an area around the vehicle are used to identify objects, and generate at least one sensing signal depending on identified objects, said control rules comprising rules for regulating the vehicle depending on said identified object. In order to be able to identify objects, according to one embodiment the sensing means comprises at least one radar unit and / or a camera unit. From the images taken by the camera, different objects can then be distinguished with appropriate computer processing. When an object is identified, according to one embodiment, the sensing means emits a sensing signal which includes information about the object's location and possible speed.
    The coordination unit is adapted to receive this information and generate control signals to different control units based on predetermined control rules. According to one embodiment, the sensing means identifies road markings along the vehicle's current direction of travel in order to assess the course of the vehicle. According to another embodiment, the sensing means identifies the road edge, railings or the like that run parallel to the vehicle's current direction of travel in order to assess which direction of travel the vehicle should have. The vehicle can then be kept on a straight course or a course according to identified objects, which means that the driver does not have to steer the vehicle but can concentrate on handling only the application.
    If no objects can be identified that can be used to steer the vehicle, then according to one embodiment, the steering rules include rules for regulating the vehicle so that the speed of the vehicle's front wheel is kept the same. In this way, the vehicle can be automatically steered to continue straight ahead, even though no objects have been identified that can give the vehicle a steering course.
    If objects are identified which are in the way of the vehicle's progress, then according to one embodiment the control rules include rules for regulating the vehicle so that the speed of the vehicle is reduced. The vehicle can also be regulated to stop completely, or to change its course to prevent a collision with an identified object.
    According to one embodiment, said control function is adapted to be deactivated when the driver himself controls / regulates the vehicle. The driver can thus deactivate the automatic steering by, for example, pressing the foot brake, accelerator pedal or turning the steering wheel. The coordination unit is then preferably adapted to receive signals from these controls, ie front brake, accelerator pedal or steering wheel, and thereby deactivate control functions and thus the automatic control. In this way, the driver can quickly regain control of the vehicle.
    An example of an application is a water cannon on a fire truck. According to one embodiment, the control system comprises sensing means adapted to locate a fire and emit a locating signal comprising information about the location of the fire, the coordination unit being adapted to emit control signals to control said water cannon in accordance with said information. The control rules then include rules for controlling said water cannon. The sensing means may, for example, be an IR unit which locates the fire by its radiated heat. The driver is then helped to set the water cannon, which increases the driver's ability to extinguish the fire effectively.
    The invention also comprises a method for automatic control of a vehicle which comprises a control system connected to one or more applications via a communication system. The method will now be described with reference to the flow chart in Figure 2. In a first step S1, the method comprises generating an activation signal. In a next step S2, at least one application is activated based on the activation signal. This can be done, for example, by the driver pressing a switch connected to the application, which activates the application. In a next step S3, a control function is activated which includes predetermined control rules for the vehicle, based on the activation signal. In connection with an application being activated, a control function is also activated in order to regulate the vehicle in accordance with the said rules. In step S4, at least one control signal is generated and transmitted to one or more control units in the vehicle in dependence on said control function, the vehicle in step S5 being automatically regulated according to said control signal. Through this method, the vehicle can be automatically regulated and the driver can concentrate on using said application and performing a task.
    According to one embodiment, the method comprises regulating the speed and / or direction of the vehicle in accordance with said predetermined control rules. The control rules can be implemented in the form of program instructions, and based on input signals to the coordination unit, control signals are generated to the control units to control the vehicle.
    To control the vehicle, according to one embodiment, an area around the vehicle is sensed to identify objects, and generate at least one sensing signal in dependence on identified objects, and regulate the vehicle in dependence on said sensed objects in accordance with said predetermined rules. By identifying objects, it is possible to steer the vehicle after these objects to keep the vehicle on a special course, or to prevent a collision with an object in the vehicle's route. For example, road markings, road edges, bridge railings, etc. can be identified, and provide a steering course for the vehicle's automatic steering.
    According to one embodiment, said application is a water cannon, and the method comprises locating a fire and emitting a locating signal which includes information about the location of the fire, and controlling said water cannon in accordance with said information. The location can be done, for example, by using heat-sensitive IR detectors. In this way, the driver can get help aiming the water cannon at the fire.
    The invention also relates to a computer program product, comprising computer program instructions for causing a computer system in a vehicle to perform the steps according to the above-mentioned method, when the computer program instructions are run on said computer system. The invention also comprises a computer program product, where the computer program instructions are stored on a medium readable by a computer system.
