PROBLEM TO BE SOLVED: To provide a vehicle communication device, capable of suppressing reduced communication quality of communication equipment and reduced operation quality of an on-vehicle apparatus, while suppressing a cost increase.SOLUTION: When on-vehicle apparatuses (14, 16) are in operation and the operation mode thereof is apt to be influenced by signal transmission from an on-vehicle communication device (20), the transmission output power of on-vehicle communication equipment is adjusted to reduce the influence. Also, when a signal exchanged between the on-vehicle communication equipment and out-vehicle communication equipment (50) is of a signal type having high importance or emergency, the transmission output power of the on-vehicle communication equipment is adjusted to hardly receive the influence of an operation noise from each on-vehicle apparatus. By this, it is possible to suppress reduced operation quality of the on-vehicle apparatus and reduced communication quality of the communication equipment. |
