The invention relates to an electronic control device for a vehicle, further to a system for activating program functions thereof, and to a corresponding method for the same. The invention allows subsequent activation, optionally at a cost, of program functions, particularly allowing commerce in such program functions. To this end, an electronic control device (2) for a vehicle (1) is provided, having an interface device for connecting to a data line (3), wherein the electronic control device comprises a plurality of program functions for performing control and regulating tasks in the vehicle, and at least a partial quantity of program functions can be deactivated, such that the electronic control device does not execute a deactivated program function, even if there is a corresponding need for control and regulating, wherein the electronic control device is set up for receiving and analyzing encoded activation information and, upon presentation of valid activation information, activates an associated program function that can be deactivated.
An electronic control device (2) for a vehicle (1) having an interface facility for connection to a data line (3), the electronic control device including a plurality of program functions for executing control and regulation tasks in the vehicle, and it being possible to deactivate at least a subset of the program functions such that the electronic control device does not execute a deactivated program function even when there is a need of corresponding control and regulation, the electronic control device being configured to receive and evaluate encrypted activation information, and a related program function, which can be deactivated, being activated on valid activation information.
The electronic control device according to at least one of the preceding claims, characterized in that the electronic control device (2) is configured to receive an activation key from an operator unit (4) installed in the vehicle (1) or from an external diagnostic device (6) that is connectable to the vehicle (1).
The electronic control device according to at least one of the preceding claims, characterized in that the electronic control device (2) is configured to receive an activation key transmitted via a wireless data connection.
The electronic control device according to at least one of the preceding claims, characterized in that the set of program functions that can be deactivated has a subset of safety-related program functions, the necessary deactivated safety-related program function being activated at least for a time when driving conditions occur for the vehicle (1) that call for control or regulation by a safety-related program function.
The electronic control device according to at least one of the preceding claims, characterized in that the electronic control device (2) is configured to control a braking system of the vehicle (1).
A method for activating program functions in an electronic control device for a vehicle, the electronic control device having a plurality of program functions for executing control and regulation tasks in the vehicle, it being possible to deactivate at least a subset of the program functions such that the electronic control device does not execute a deactivated program function even when there is a need of corresponding control and regulation, it being possible to supply encrypted activation information to the electronic control device, the electronic control device decrypting the encrypted activation information and on valid activation information, activating a related deactivated program function.
A system for activating program functions in an electronic control device (2) according to one of the preceding claims, with a database (9) for managing license information and/or activation keys for activating program functions in the electronic control device (2).
