Linear pulling influence method for a vehicle comprises using an emitter for carrying out frequency modulation of the transmitted signal frequency of a number of transmitted signal frequencies

摘要

Linear pulling influence method comprises using an emitter for carrying out frequency modulation of the transmitted signal frequency of a number of transmitted signal frequencies. Independent claims are also included for the following: (1) Emitter with units for converting a signal into a code by selecting one or more signal frequencies and for transmitting a selected signal frequency to a receiver of a vehicle; and (2) Receiver with units for receiving a code in the form of one or more signal frequencies. Preferred Features: A square wave signal is modulated to the transmitted signal frequency, especially to one of the transmitted signal frequencies, by the emitter.
