Abstract
A method for authorizing the use of a motor, having at least one first vehicle antenna and one second vehicle antenna located at a spatial distance from one another, includes transmitting, by the first vehicle antenna, a first signal that is received by an identification provider antenna of a portable identification provider, and ascertaining, by the portable identification provider, at least one spatial component of a first electromagnetic field of the received first signal using an angle-resolving magnetic field sensor. The method also includes transmitting, by the second vehicle antenna, a second signal that is received by the identification provider antenna, and ascertaining, by the portable identification provider, at least one spatial component of a second electromagnetic field of the received second signal using the angle-resolving magnetic field sensor. An angle at least between the ascertained at least one spatial component of the first electromagnetic field and the ascertained at least one spatial component of the second electromagnetic field is then determined.
