A system for delivering shipping items in vehicles includes a first communication module establishing a communication link to a communication terminal of a delivery person, the communication terminal receiving authorization data via a communication network; a first identification routine unambiguously identifying a delivery person; a second communication module establishing, via a wireless communication network, a communication link to a communication device of a control unit of the access arrangement on a vehicle; a second identification routine for unambiguously identifying the system by the access arrangement; a third communication module for receiving update request data from the driver; and an update routine for updating authorization data in a memory of the system. Upon updating authorization data, information is wirelessly transmitted relating to the successful delivery and the content of the delivery to the access arrangement. The driver assistance system displays an alert message about the delivery.

The present disclosure relates to automobiles and, more specifically, teaches methods and systems that may be used for wirelessly charging batteries used in vehicles. In one embodiment, a method for detecting a relative position between a vehicle-side receiving charging coil and a fixed transmission charging coil, may include: generating an alternating magnetic orientation field using one of the coils; detecting the orientation field using at least one coil provided for inductive excitation, wherein the orientation field is detected in a frequency-selective manner by the at least one coil; and ascertaining the relative position using an orientation receiving signal induced by the orientation field in the at least one coil.

A system for selectively opening a vehicle includes a first communication module for establishing a communication link to a service provider who obtains authorization data via a communication network, a first identification routine for unambiguously identifying the service provider, and a second communication module for establishing, via wireless communication, a communication link to a control unit of an access arrangement on a vehicle. A second identification routine allows the access arrangement to unambiguously identify the system. A third communication module receives update request data from the driver. An update routine updates authorization data in a memory of the system. When authorization is valid, the control unit receives a profiled control signal via the communication link, the profiled control signal causing the vehicle to be selectively opened via the control unit.

A system for transmitting baggage items in vehicles, having a first communication module for communicating with a communication terminal that requests authorization data via a network, an identification routine that identifies a supplier, a second communication module for communication to a control device of an access system for a vehicle, a second identification routine for identification of the system by the access system, a third communication module for receiving request information (AA) from the driver, and an updating routine for updating authorization data of the system. A baggage detection unit detects baggage items loaded into the vehicle. Data regarding the baggage items is transmitted to a logistics service provider and after executing the updating routine transmits information on the baggage items to the vehicle access system. The control device of the access system generates a message regarding the transmission of baggage items via a bus system in the vehicle.

A method for assisting in maintenance of a motor vehicle having a drive motor, an drive energy storage device, and a filling level measuring device. A request for a maintenance process is identified by a self-monitoring device with the maintenance request being transmitted as a maintenance indication to a driver by an information device. The maintenance indication is transmitted to the driver as a function of a switch-off filling level present when the vehicle drive motor is switched off and detected by the filling level measuring device. The maintenance indication is transmitted when the switch-off filling level is lower than a preset filling level threshold value or when a filling level difference between a switch-on filling level, present when the vehicle drive motor is subsequently switched on again and detected by the filling level measuring device, and the preceding switch-off filling level indicates a positive filling level value.

In an adaptive positioning method for an actuator, in particular, for a throttle butterfly on an internal combustion engine, during the adaptive positioning method, after a request for a set position and selection of a pilot value a corresponding pilot position for the actuator is adopted. The pilot position is adjusted until said position corresponds to the requested set position. The control value actually required or this set position is subsequently measured and recorded as corrected pilot value for the corresponding set position.

In an adaptation method of an internal combustion engine for optimized combustion, the actually supplied cylinder-specific air masses are determined by determining the change in speed of the internal combustion engine within a thrust phase and by assigning these changes in speed to the cylinder-specific compression phases. This enables the fuel quantity to be injected to be more precisely adjusted to the cylinder-specific air mass available.
