In the method at least one software component is exported from a software development environment for the operating software of the controller to be replaced by a data processing apparatus. The software component is converted into a code, which can be imported into a software development environment for the operating software of the functional and/or new controller, by the data processing apparatus. The code is imported into the software development environment of the operating software of the functional and/or new controller by the data processing apparatus. The operating software for the new controller is produced on the basis of the imported code. | 01-26-2012 |
| 20120016556 | METHOD AND DEVICE FOR DETECTING AND COMPENSATING FOR A TRANSVERSE INCLINATION OF A ROADWAY ON WHICH A VEHICLE IS TRAVELING - A method and a device detect a transverse inclination of a roadway on which a vehicle is traveling. The transverse inclination is detected on the basis of a transverse acceleration of the vehicle that is generated by the transverse inclination of the roadway. A transverse acceleration of the vehicle is measured with a measuring device. A transverse acceleration that is generated by driving maneuvers of the vehicle is determined by a transverse inclination observer. The transverse acceleration of the vehicle due to the transverse inclination of the roadway is subsequently determined by determining a difference between the transverse acceleration generated by the driving maneuvers and the transverse acceleration measured by the measuring device. A method and a device are also provided for compensating for the transverse inclination of the roadway on which a vehicle is traveling. A steering angle which compensates for the transverse acceleration of the vehicle that is caused by the transverse inclination of the roadway, by way of a transverse inclination compensator. The steering angle is set by taking into consideration the transverse acceleration of the vehicle caused by the transverse inclination of the roadway. | 01-19-2012 |
