Method, apparatuses and arrangement for establishing a wireless connection between a vehicle and a vehicle accessory

A vehicle arrangement comprising:

• a vehicle comprising a vehicle wireless transceiver;
• an accessory comprising an accessory wireless transceiver;
• a wired communication channel between the vehicle and the accessory;
• a vehicle control unit configured to:
• detect the wired communication channel between the vehicle and the accessory;
• transmit a vehicle identifier from the vehicle to the accessory via the wired communication channel;
• receive an accessory identifier via the wired communication channel;
• derive a unique code based on the vehicle identifier and the accessory identifier using a predetermined function;
• broadcast the unique code;
• in the vehicle accessory:
• derive a unique code based on the vehicle identifier and the accessory identifier using the same predetermined function as used in the vehicle;
• receive the broadcast unique code;
• determine that the received unique code corresponds to the determined unique code;
• find the network broadcasting the unique code;
• and
• establish a wireless connection between the vehicle and the vehicle accessory using the network characterized by the unique code.

A computer program comprising program code means for performing the following steps when said program is run on a vehicle control unit of a vehicle and on a corresponding accessory control unit in a vehicle accessory:

• detecting a wired communication channel between the vehicle and the accessory;
• transmitting a vehicle identifier from the vehicle to the accessory via the wired communication channel;
• receiving an accessory identifier via the wired communication channel;
• deriving a unique code based on the vehicle identifier and the accessory identifier using a predetermined function;
• broadcasting the unique code by the vehicle wireless transceiver;
• in the vehicle accessory:
• deriving the unique code based on the received vehicle identifier and the accessory identifier using the same predetermined function as used in the vehicle;
• receiving the broadcast unique code by the accessory wireless transceiver;
• determining that the received unique code corresponds to the determined unique code;
• finding a network broadcasting the unique code by the accessory wireless transceiver;
• and
• establishing a wireless connection between the wireless transceiver of the vehicle and the wireless transceiver of the accessory using the network characterized by the unique code.

A vehicle control unit for controlling a vehicle wireless transceiver and an accessory control unit for controlling an accessory wireless transceiver to establish a wireless connection between a vehicle and an accessory, the vehicle control unit and the accessory control unit being configured to perform the following steps:

• detecting a wired communication channel between the vehicle and the accessory;
• transmitting a vehicle identifier from the vehicle to the accessory via the wired communication channel;
• receiving an accessory identifier via the wired communication channel;
• deriving a unique code based on the vehicle identifier and the accessory identifier using a predetermined function;
• broadcasting the unique code by the vehicle wireless transceiver;
• in the vehicle accessory:
• deriving the unique code based on the received vehicle identifier and the accessory identifier using the same predetermined function as used in the vehicle;
• receiving the broadcast unique code by the accessory wireless transceiver;
• determining that the received unique code corresponds to the determined unique code;
• finding a network broadcasting the unique code by the accessory wireless transceiver;
• and
• establishing a wireless connection between the wireless transceiver of the vehicle and the wireless transceiver of the accessory using the network characterized by the unique code.
