Japanese Patent JP6751153
Kind Code:
B2
Abstract:
A motor includes at least a first and a second antenna, wherein the antennas are arranged spaced apart spatially from one another, by means of a portable identification signal generator which has an identification signal generator antenna. In order to improve the protection against tampering, the first vehicle antenna outputs a first signal which is received by the identification signal generator antenna. The identification signal generator determines at least one of the spatial components of the first electromagnetic field of the received first signal. The second vehicle antenna outputs a second signal which is received by the identification signal generator antenna. The identification signal generator determines at least one of the spatial components of the second electromagnetic field of the received second signal. The identification signal generator transmits the data to the vehicle. A computer determines the angle at least between the special components of the signals.
