Method for authorization in a wireless vehicle network
A method for authorization in a wireless vehicle network is disclosed. In particular, the method is for authorizing communication between a mobile communications unit and a vehicle-based communications unit assigned to a control unit in a vehicle, wherein there is an unauthorized connection between the mobile communications unit and the vehicle-based communications unit. In the method, the mobile unit sends to the vehicle-based unit a request to authorize communication. Thereupon, the vehicle-based unit sends to the mobile unit from which the request came, an instruction to perform an action on the vehicle. An operator who has access to the mobile unit and to the vehicle performs the action. The control unit detects the performed action. The vehicle-based unit authorizes communication with the mobile unit.
1. A method for authorizing communication between a first vehicle-based communications unit of a first vehicle, the first vehicle-based communications unit being assigned to a first control unit, and a second vehicle-based communications unit of a second vehicle, the second vehicle-based communications unit being assigned to a second control unit, wherein there is a physical-mechanical connection between the two vehicles, wherein there is an unauthorized wireless connection between the first and second vehicle-based communications units, wherein the first vehicle-based communications unit sends to the second vehicle-based communications unit via the wireless connection a request to authorize communication, and wherein one of the two alternatives a) or b) is performed:
a) one of the first and second vehicle-based communications units prompts the other of the first and second vehicle-based communications units via the wireless connection for an acknowledgment, the acknowledgment is made on the physical-mechanical connection, and an authorized wireless connection is set up; or
b) one of the first and second vehicle-based communications units prompts the other of the first and second vehicle-based communications units via the physical-mechanical connection for an acknowledgment, the acknowledgment is made via the wireless connection or via the physical-mechanical connection, and an authorized wireless connection is set up.
2. The method as claimed in claim 1 wherein alternative a) is performed.
3. The method as claimed in claim 1 wherein alternative b) is performed.
