Description

Method for wirelessly connecting an external device to a vehicle for enabling communication between the external device and the vehicle.
TECHNICAL FIELD
5 The invention relates to a method according to the preamble of daim 1. The invention relates to a system according to the preamble of claim 11. The invention also relates to a motor vehicle. The invention also relates to a computer program and a computer program product.
10 BACKGROUND
In vehicles such as trucks, external devices with wireless connection are today used to communicate with the vehicle. Such external devices are used to control functions in the vehicle, e.g. to set the heater of the vehicle, to raise and lower the vehicle, to control the tail lift of a vehicle equipped with such 15 devices, to control the lighting of the vehicle, to lock/unlock the vehicle, etc. A potential problem is that the user of the external device may not be authorised to control such functions in the vehicle.
OBJECT OF THE INVENTION
20 One object of the present invention is to achieve a method and a system for wireless connection of an external device for communication with a vehicle, which facilitates the determination of the authority of the user of the external device. SUMMARY OF THE INVENTION
These and other objectives, which are set out in the description below, are achieved with a method, a system, a motor vehicle, a computer program and a computer program product of the type specified above, and which also have the features specified in the characterising portions of the appended independent claims. The 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 according to the independent claim 1 and a system according to the independent system claim.
According to the invention, the objects are achieved with a method for wireless connection of an external device for communication with a vehicle, comprising the steps: to initiate the connection with the vehicle; to determine the identity of the current driver of the vehicle; to determine the identity of the current user of the external device; and to compare the thus determined identities in order to decide whether the current user of the external device is the same person as the current driver of the vehicle.
Hereby, it is possible to determine whether the user of the external device is the driver of the vehicle, which accordingly facilitates the determination of the authority of the user of the external device.
According to one embodiment, the method comprises a step of storing at least one driver identity in a server unit for this purpose. By using a server unit, it is possible for the vehicle owner to cancel a user's authority. With the server unit it is possible to change the status via the server unit, e.g. so that the external device no longer has access to the vehicle.
According to one embodiment of the method, the step of comparing the thus determined identities comprises encryption of the identities. Thus, unauthorised access of the external device to communicate with the vehicle is made more difficult.
According to one embodiment, the method comprises the step of requesting different provided functions with respect to the vehicle through the external device operated by the current driver. Thus the authorised driver may, via the external device, externally control functions in the vehicle, such as raising and lowering, tail lift, temperature control in the vehicle, lighting, locking/unlocking of the vehicle, etc.
According to one embodiment, the method comprises the step of connecting and specifying authority for the current driver of the vehicle to use the provided functions. Thus, when using the external device, the driver of the vehicle is able to use only those functions in the vehicle, which the driver is authorised to use. For example, all drivers in a haulage firm should be able to set the heater to a timer, whereas only the owner of the haulage should be able to unlock a vehicle.
According to one embodiment, the method comprises the step of performing, via the server unit, at least some communication comprising the vehicle and the external device. This makes it possible to have stored driver information, vehicle-specific information, authorisation information for specific vehicles, authorisation connected to specific vehicle owners in the server unit. According to one variant, a user account is created for a specific user/driver, wherein authority for specific vehicles and/or for specific vehicle owners is stored, so that the user of the external device may login to his/her user account, to access the vehicle in order to control vehicle functions via the external device. Certain communication comprising the vehicle and the external device accordingly relates to communicating, via the server unit, one or several of: driver information, vehicle-specific information, authorisation information for specific vehicles, authorisation connected with a specific vehicle owner. According to one embodiment of the method, the step of determining the identity of the current driver of the vehicle comprises detection of driver characteristics. This enables efficient identification of the driver, for comparison with the identity of the user of the external device. According to one embodiment of the method, said driver characteristics comprise biometric characteristics and/or driver card identity. This enables efficient identification of the driver, for comparison with the identity of the user of the external device.
According to one embodiment of the method, the step of determining the identity of the current user of the external device comprises detection of the user characteristics. This facilitates efficient identification of the user of the external device, for comparison with the identity of the driver.
According to one embodiment of the method, said user characteristics comprise biometric characteristics and/or personal code and/or driver card identity. This facilitates efficient identification of the user of the external device, for comparison with the identity of the driver.
The system requirements have advantages similar to the advantages mentioned above for corresponding method claims.
