ABSTRACT:
A method for reinitializing vehicle parameters stored in a memory of a controller in a motor vehicle after a power loss to the controller includes the steps of determining whether predetermined conditions are right for transferring at least one vehicle parameter stored in a volatile memory of a controller, transferring the vehicle parameter stored in the volatile memory to a non-volatile memory if the predetermined conditions are right for transferring the vehicle parameter, determining whether predetermined conditions are right for re-initializing the vehicle parameter after a power loss to the controller, transferring the vehicle parameter from the non-volatile memory to the volatile memory if the predetermined conditions are right for re-initializing the vehicle parameter, and initializing the vehicle parameter with a predetermined initial value stored in the non-volatile memory to the volatile memory if the predetermined conditions are not right for re-initializing the vehicle parameter.
