Abstract
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.
