Systems and methods for operating a vehicle that may be driven to or sold in different geographical locations that may have different engine emissions and fuel economy standards are described. The systems and methods may adjust vehicle operation to comply with standards that may be enforced where the vehicle is geographically located. The standards may apply to countries, treaty zones, race track areas, off-road areas, and other geographically related standards.

A method is for calibrating a pivot angle sensor of a hydraulic machine of a propulsion or working machine. A control device is configured to operationally control the hydraulic machine. The control device is also configured to process a sensor signal from the pivot angle sensor. The pivot angle sensor is calibrated, preferably in an automated manner, via the control device.

By using various feedback data on a sprayer system, such as engine speed, wheel speed, sensed temperatures and/or sensed pressures, an onboard logic controller can be used to fine tune parameters of the driveline system in an automatic calibration process. In one aspect, a controller can drive up engine speed and manipulate electrical current being sent to coils of propel pumps and/or wheel motors as current reaches a point where there is no more change in wheel speed as detected by the system, thereby achieving a. calibration setpoint. Additionally, during the automatic calibration process, the machine as a whole can be monitored with respect to several sensors, such as pressures, temperatures, and the like, so that if any parameter being monitored is out of a predetermined range, the calibration can be stopped and not set.

Method and apparatus are disclosed for vehicle calibration based upon performance product detection. An example vehicle includes a receiver to receive a wireless signal from a transducer of an performance product that includes characteristics of the performance product. The example vehicle also includes a product controller to authenticate the performance product based upon the wireless signal and send, upon authentication, a calibration instruction that includes the characteristics. The example vehicle also includes an electronic control unit to receive the calibration instruction and adjust a calibration to a target setting based upon the characteristics.

A system for determining a torque converter clutch is stuck in an engaged position includes a control module, an engine speed sensor, and a transmission speed sensor. The control module evaluates the torque converter clutch by determining a value of a torque converter clutch command. The torque converter clutch command indicates a position of the torque converter clutch. In response to determining that the value of the torque converter clutch command indicates the disengaged position, the control module calculates accumulated slip based on the transmission speed and the engine speed during an evaluation time. In response to determining the evaluation time is complete, the control module compares the accumulated slip with a calibrated threshold of slip. In response to the accumulated slip being less than or equal to the calibrated threshold of slip, the control module determines the torque converter clutch is stuck in the engaged position.

A method for determining the position of a first actuating element of an electrical parking lock device of a motor vehicle, wherein the first actuating element is mounted on a spindle in an axially mobile manner, where the method includes a step in which the first actuating element is moved in an opening direction to a stop, the spindle is then rotated to move the first actuating element in a closing direction, the current input and the energy consumption of a driver are captured at this point, provision is then made for identifying a first reference point if the current input of the spindle drive increases or decreases by at least a first threshold value, the first reference point is assigned to the energy consumption that has been captured, where the first reference point corresponds to the first actuating element coming into contact with an actuating pawl.
