The present disclosure, in one aspect, provides a method for monitoring a vehicle environment. The method may include determining environmental data of a vehicle with an environmental sensor system, transmitting the environmental data to a mobile unit, determining a local position of the mobile unit with respect to the vehicle, and selecting a subset of the environmental data based on the local position of the mobile unit and depicting the subset of the environmental data on the mobile unit.

Position-dependent representation of vehicle environment data on a mobile unit

The disclosure relates to a pivot angle detection device and a method for detecting a pivot angle between a vehicle and a trailer coupling device that is coupled to the vehicle. A transmitter is hereby provided, which is designed for producing an electromagnetic field, as well as a receiver which is designed to detect a field strength of the electromagnetic field, whereby the transmitter and receiver are arranged towards each other on the vehicle and trailer coupling device in such a way that a change of the pivot angle produces a dependent change in the field strength that is detected by the receiver. Additionally, an evaluation device for determining the pivot angle based on the detected field strength is also provided. The disclosure also relates to a transmitter, a receiver and an evaluation device, that are designed for this purpose.

Device and method for detecting a pivot angle between a vehicle and a trailer device

The invention concerns a method for controlling a motor vehicle drivetrain which comprises a drive motor, a multi-step, automated change-speed transmission and an automated separating clutch arranged between the drive motor and the transmission, and a shifting device with a selector lever which can be moved at least from a particular position in an upshift direction ('+' direction) for manually initiating an upshift and in a downshift direction ('&#x2212;') for manually initiating a downshift, and in which the transmission and the separating clutch can be controlled by a transmission control unit which is connected at least to a speed sensor, a brake pedal actuation sensor and a selector lever actuation sensor, such that when the motor vehicle is rolling with its drivetrain open the closing of the drivetrain is initiated by actuating the selector lever. To improve the functional safety it is provided that when a first movement of the selector lever in a shift direction (&#x201c;+&#x201d; direction or &#x201c;&#x2212;&#x201d; direction) is sensed, this is interpreted as a provisional command to close the drivetrain, and if a second movement of the selector lever in the same shift direction (&#x201c;+&#x201d; direction or &#x201c;&#x2212;&#x201d; direction) is sensed within a specified confirmation time (&#x394;t), this is interpreted as a confirmation of the provisional command to close the drivetrain and, as an implementation command, initiates the closing of the drivetrain.
