Title:
ON-VEHICLE RADIO SYSTEM
Document Type and Number:
Japanese Patent JP2020120186
Kind Code:
A
Abstract:
To provide an on-vehicle radio system capable of reducing the influence of radio noise generated due to a carrier frequency used for controlling the rotation speed of an electric motor without lowering the efficiency of the electric motor.SOLUTION: An on-vehicle radio system includes a radio amplifier unit (10) that expands an audio signal carried by received radio waves such that the audio signal can be heard, and the radio amplifier unit includes an attenuation processing unit (11) that attenuates radio waves of a frequency value that is obtained by multiplying the integer of a carrier frequency included in the frequency band of the received radio waves on the basis of carrier frequency information obtained from a control device (100) that transmits a signal of the carrier frequency determined to drive a motor (120) mounted on an electric vehicle at a designated rotation speed to an inverter (110) connected to the motor, and the attenuation processing unit performs attenuation processing of attenuating a radio wave having a frequency in which the value of the frequency obtained by multiplying the integer matches the value of the frequency of the received radio wave.SELECTED DRAWING: Figure 1
