Method for determining relative horizontal angle between car and transmitter for car-to-X communication purposes, involves providing evaluation unit evaluating error function, and determining angle based on values of error function

摘要

The method involves providing an evaluation unit that evaluates an error function in dependence of an actual difference and a theoretical difference for a number of horizontal angles (alpha, beta), where the theoretical difference is a difference between a theoretical reception power of a reference range and another theoretical reception power of a remaining receipt range. The evaluation unit determines a relative horizontal angle based on function values of the error function. An independent claim is also included for a device for determining a relative horizontal angle between a vehicle and a transmitter.
